Description
Descri~ton Notepaper Dispensing ~ray Technical Field . .
The present invention relates to an improvement in a tray for supporting notepaper, and in one aspect to a new configuration of a tray ~or supporting the stack of notepaper to permit dispensing single sheets from a stack of notepaper without separatin~ the stack from the support.
sackground Art Notepaper has become commercially available by the assignee of this application, Minnesota Mining and Manufacturing Company, St. Paul, Minnesota U.S.A. wherein the stack of sheet material comprises a plurality of sheets each of which are coated with a narrow band of readily releasable pressure-sensitive adhesive along one ed~e and the sheets are stacked with the adhesive coated edge of each sheet positioned above each other adhesive coated edge. The band of adhesive ranges between one-quarter and three-quarters of an inch wide~ The individual sheets may be readily withdrawn from the stack by peeling the sheet and its adhesive from the next adjacent sheet in the stack.
The adhe~ive is a readily repositionable pressure-sensitive adhesive such that the separated sheet may be attached to another sheet or other receptor sur~ace and readily removed withou~ tea~in~ the Eiber~ of the othcr ~h~t or r~c~ltor surface upon later separating the sheet.
A stack of this notepaper is adapted to be supported on a holder such as is disclosed in U.S.A.
Letters Patent No. Des. 273,798 issued May 8, 1984. This particular prior holder had a surface for supporting the stack of sheet material and relied on the adhesive on the surface o~ the lower sheet of the stack or on an additional strip o~ adhesive to secure the stack of sheets or pad to the support surface on the holder~ After several uses of the pad holder, it was noted that the surface would become ~ 76~2 soiled or the strip of adhesive applied to the holder became contaminated such tha~ the pad was no-t secure enough tc, the holder to permit separation or one sheet from the stack without the separating force being sufficient to also separa~e the entire stack from the holder, particularly as the number of sheets in the stack was depleted. Therefore, improvements in holders for dispensing the pressure-sensitive adhesive coated notepapers from a stack became desirable.
The present invention describes an improved notepaper dispenser which a-ffords a support surface for supporting a stack or pad of sheet material and on a surface which permits writing on the notepaper before the same is removed from the s-tack. Further, the holder of the present invention provides means for holding the bottom sheet in a stack against movement in the plane of the support surface. The holder for the notepaper is provided with abutment means which projects above the plane of the support surface supporting the notepaper to restrict movement of the stack during the separation of ~he uppermost sheet from the stack and peeling forces from being applied to the band of adhesive on the lowermost sheets.
_isclosure of Invention The present invention relates to an improvement in notepaper dispensers and particularly to an improvement in holders for pads of notepaper which comprise sheets held together with a narrow band of pressure sensitive adhesive material. The holder permits the sheets to be dispensed individually ancl holds a stack B f sheets such that the forces imparted to the stack during the sq~
separation of the individual sheets will not separate the stack from the holder.
The invention provides a dispenser for a stack of sheet material comprising sheets joined in the stack by a narrow band of pressure-sensitive adhesive on one side of each sheet ad]acent one end and affording dispensing of single sheets from the stack and separation of the adh~sive coated end of the single sheet from the remaininy sheets in the stack, said dispenser comprising: a support member having a generally planar support surface for supporting the stack of sheet material, clamping means cooperating with said support surface for engaging the lowermost sheet of said stack between said adhesive coated end and the other end opposite said coated end, and fixing said sheet in relationship to the support, and abut.ment means pro3ecting above the plane of the support surface for engaging said other end of said stack for cooperating with said clamping means for restricting movement of said stack in relationship to the support surface during separation of the top sheet from a said stack, wherein said clamping means cooperating with said support surface comprises a clamping plate adapted to be positioned over a lowermost sheet in a said stack and said clamping plate is formed with a clamp member comprising a flange connected to the forward edye of the clamping plate and extending transversely of the support member and a second plate member positioned beneath the support member which is normally spaced from the clamping plate by a distance less than the thickness of the support member to urge the clamping plate toward -the support surface to frictionally fix said lowermost 7 E;22 sheet onto said support surface.
The invention also provides a dispenser for a stack of sheet material comprising sheets joined in the s~ack by a narrow band of pressure-sensitive adhesive on one side of each sheet adjacent one end and affordiny dispensing of single sheets from the stack and separation of the adhesive coated end of the single sheet from the remaining sheets in the stack, said dispenser comprising: a support member having a generally planar support surface for supporting the stack of sheat material, clamping means cooperating with said support surface for engaging the lowermost sheet of said stack between said adhesive coated end and the other end opposite said coated end, and fixing said sheet in relationship to the support, and abutment means projecting above the plane of the support surface for engaging said other end of said stack for cooperating with said clamping means for restricting movement of said stack in relationship to the support surface during separation of the top sheet from a said stack, wherein said clamping means cooperating with said support surface comprises a plate extending transversely of the support member, ~0 said plate having clamp members at the ends thereof which cooperate with ~he ends of the support member to frictionally engage the ends of said support member adjacent the edges of said support surface for holding the plate and the bottom sheet of a said stack against movement in the plane of the support surface, said plate havi.ng said abutment means affixed thereto to engage the sheets along the front edge of the support member.
The invention further provides a dispenser for a stack :~ 3 ~
" ~S7~22 of sheet material comprising sheets joined in the stack by a narrow band of pressure-sensitive adhesive on one side of each sheet adjacent one edge of the stack and affording dispensing of single sheets from the stack and se~aration of the adhesive coated end of the single sheet from the remaininy sheets in the stack, said dispenser compris.ing a support member having a generally planar support surface for supporting said one edge of the stack of sheet material, a plate member positioned on said support member and movable with respect to said support member, means afforcling limited movement of said plate member with respec~ to said support member for inserting the adhesive-free portion of the lowermost sheet in a said stack between said plate member and said support member, an abutment member formed along an edge of said plate member and projecting from the surface of said plate member supporting said stack to engage the edge of the stack of sheets opposite said one edge and projection means projecting from the opposite surface of said plate member for penetrating a said lowermost sheet in a said stack, said projection means being positioned on said plate member to penetrate a said sheet when said edge of said stack opposite saicl one edge is contacting saicl abu-tment.
The clamping action may be afforded by physical forces applied to the lowermost sheet, such as frictional forces applied by weight, by springs, by the use of magnets, or by physically bending the lowermost sheet such that increased forces are needed to release the lowermost sheet from the support surface.

Detailed DescriEtion Referring now to Figure 1 there is illustrated a dispenser for a stack of notepaper, which dispen~er iB
generally designated by the reference numeral 11 and compri~e~ a main Erame 12 which may be molded and formed of joined parts to have an inner cavity 13 which may be filled with a sand or other heavy material to weight the dispenser~ The frame 12 has a bottom plate 14, a rear wall ~ 7~i22 15, opposed side walls 16 and 17, between which extend a generally planar support 20 for a stack of sheet material.
The support 20 extends from the front edge 21 of the holder to a generally vertical member 22, which woul~ be at one end of the stack 30 of sheet material and which, at its upper end, connects with the top 23 of the frame 12. The top 23 is shaped to form a cradle for a writing instrument and con-tinues to a well 24 shaped to receive a refill stack of notepaper, paper clips, or the upper sur~ace surrounding the well 2~ may support a nameplate, etc.
Supported for pivotal movement relative to the frame 12 is a platen or planar clampin~ plate 25 which is adapted ~or clamping the lowermost sheet 26 of a stack of sheets 30 onto the frame 12 of the holder~ As illustrated in Figures 1, 2 and 3, the plate 25 is adapted to pivot relative to the frame 12 and cooperates with the support 20 to firmly hol~ the lowermost sheet 26 in a position between the support 20 and the under side of the plate 25 to restrict movement of the sheet 26 with respect to the plane of the support 20. Extending upwardly from the ~orward end of the plate 25 is an abutment 31 which engages the edge of the lowermost sheets in the stack. The abutment 31 serves to restrict movement of a stack of sheets with respect to the platen 25 and support 20 during separation of the uppermost sheet in the stack. During the peeling or stripping movement when separating one sheet from the stack 30 the stack ~ends to li~t adjacent th~ edge where the sheets are joined, driving the stack ~orward or to apply a rotational or torsional force to be transmitte~ to the stack. These forces will be absorbed by the abutment and restrict movement of the pad with respect to the support and translates the forces to shear forces on the bands of adhesive joining the sheet~ to restrict separation of the stack ~rom the lowermost sheet.
Figure 3 illustrates in sectional view a stack 30 of sheet material on the dispenser 11 with the lowermost sheet 26 clamped between the platen 25 and the support ~;7~
surface 20. The clamp holds the lower sheet at a position adjacent the edge where the sheets are joined ~ogether as illustrated. This restricts a lifting and peeling force to be exerted between the lower sheet and the pad.
The pad or stack of sheet material illustrated comprises sheets of notepaper, approximately twenty pound bond paper, with each sheet coated along one edge with a readily repositionable pressure-sensitive adhesive. The adhesive is coated in a band about one-quarter to three quarters of an inch wide.
L~`igures 4, 5 and 6 illustrate the de~ail~ of the clamping plate and the support. The main frame 12 is provided at its forward end with a cut~away as illustrated at 34 to leave a narrow resilient finger 35 extendin~ along the lateral edge o~ the frame 12. Extending outward from the finger 35 is a fulcrum member 37 which defines the fulcrum for the pivoting clamping plate 25. Also extending outwardly from the lateral edge of the frame 12 is a stop member 39 which is spaced from the front edge of the frame 12.
~ s illustrated in Figures 4 and 5, the platen 25 is formed with depending side members 40 which cover the lateral edges of the frame 12 and the cover members 40 are provided with interior recesses cooperating with the fulcrum members 37 and the stop members 39 affording limited pivotal movement of the plate 25 and positioning of the plate 25.
As illustrated in Figures 2, 3 and 6, the under surface of the clamping plate 25 may be provided with transversely spaced pointed projections 45 which extend from the under surface of the plate 25 and cooperate with recesses 46 in the support member 20 such that upon insertion o~ the lowermo~t sheet 26 in the stack 30 the projection~ 45 will penetrate the sheet and hold the sheet securely against movement with respect to the support 20.
The clamping plate 25 could also be formed with a resilient detent similar to the stop ~ember 39 which would ~.~S7~
loc~ in a cooperating rece~s to frictionally hold the bottom sheet 26 securely between the support 20 and plate 25.
The dispenser 11 with the pivoted clamping plate 25 locks the lowermost sheet in position and holds the paper in a predetermined plane with respect to the support 20 and the plate 25 such that the user may write on the sheets of notepaper before separation from the stack down to the very last sheet without encountering an uneven writing surface beneath the next to the last sheet in the stack~
A second embodiment of the invention is illustrated in Figure 7 which illustrates a dispenser generally designated 51 comprising meAns defining a frame having means defining a support surface 52. Embedded in the support ~urface 52 and extending transversely thereof are a pair of permanent magnet~ 53 and 54 which are bars of a permanent magnetic material. A clamping plate 55 formed of a magnetic material may be inserted between the lowermost sheet 26 of a stack oE sheet material and the next adjacent sheet and the ~agnets 53 and 54 will clamp the sheet against the support 52 with sufficient force to hold the sheet 26 and the stack 30 against movernent with respect to the support surface. The magnetic plate 55 is provided with a raised and transversely extending abutment 57 which enga~3es one or more of the 3heets in the stack adjacent the front edge of the stack to hold the stack against movement.
~lso, the end 59 of the plate 55 may be bend downwardly acro~ the width of the plate to position the plate with respect to the front edge 60 of the holder, and position the opposite edge of the plate adjacent the adhe~ive band of the stack.
In a further embodiment of the invention as illu~trated in Figure 8 the dispenser 61 may have a frame formed of wood, stone, or other solid rnaterial and shaped to define a ~upport surface 62. ThG ~upport surface 62 may be formed on a surface recessed between edges 63 and 64 to ~762~
afford an improved artistic design for supporting the notepaper. In this embodiment the stack 30 of notepaper is positioned within the recessed area and the lowermost sheet in the stack is clamped between a clamping plate member 65 and the support surface 62 as illustrated in Figure 8~ The clamping plate 65 as shown more clearly in phantom view in Figure 8 and partially in section appears generally U-shaped comprises an upper support plate 66 that fits over the lowermost sheet in the stack and forms a support or wr.iting surface for the sheet material. Bent ~rom the surface of the plate 66 and extending upwardly therefrom is ~n abutment member 67 which engages the front edge of the sheets in the stack 30. The clamping plate 66 has a depending flange portion 68 which has a thickness equal to or slightly greater than the height of the front edge 69 of the holder 61 and has a lower locking plate 70 which fits beneath the holder 61 and the support surface 62 thereof.
In operation, as the clamping plate 67 is inserted over the lowermost sheet and moved rearwardly with respect to the recess in the holder 61, the normal resilience of the material forming the clamping plate 67 pinches or binds and frictionally holds the lowermost sheet of the stack firmly on the support 62. The abutment 67 in the meantime enqages the front edge of the stack to restrict any rotational movement of the stack with respect to the ~upport plate 650 A similar embodiment for a notepad holder and dispenser is illustrated in Figure 9r This holder, generally designated 71, formed of a solid material and generally wedge ~haped, ha~ an wpper support surface 72 for 3upporting the tack 30 of notepaper. A clamping plate Eor clamping the lowermost sheet in the stack to the holder 71 and in po~ition on the support ~urface 72 compriqes a clamping member 73 comprising a clamping plate 7~ adapted to extend over the lowermost sheet in the stack and to suppsrt the stack and clamp the lo:.armo~t sheet against the support surface 72. Extending upward from and cut from the ~2576~2 _9_ plate 7~ defining the support platen i,s a bent flange portion 75 defining an abutment member engaying the stack 30 along the lower ~ront edge of the sheet material.
The plate 74 is joined to generally U-shaped clamping members including sidewalls 76 which are trapazodial in shape to conform substantially to the shape of the ends 77 of the frame forming the holder 71. To these side members 76 are connected reversely turned flanges 78 serving to hold the plate 74 to the holder 71 when the support plate is slid up over the ~rame between lowermost sheet in the stack and the next sheet to a position near the coating of adhesive on the lowermost sheet to clamp the lower sheet in place.
Figure lO shows a further embodiment which comprises a holder for notepaper which is a unitary member without detachable pieces or pivotally joined pieces. In Figure lO the d;spenser 81 comprises a frame 82 which may be molded of a suitable material and provided with a support surface 8~ for ~upporting the stack 30 of note-paper. In this embodiment the lowermost sheet 26 is heldtightly to the support surface 84 by the sheet being directly sharply back upon itself and then reversely directed again to bind the sheet in a narrow slot 85 defined by ~enerally parallel wall members Eormed in the support plate 8~ at an acute angle to support plate 84 which thus clamps the sheet 26 against vertical movement with respect to the support 84~ An abutment 86 is forrned at the front edge of the holder and of the support surface 84 to engage the lowermost sheet~ in the stack to re~trict movement of the stack as the result o~ the lifting and peeling forceA applied to remove a sheet -from the ~tack of sheets 30.
To place the stack of sheets on the holder 81, the lowermo~t sheet is peeled from the ~orward edge of the pad and then directed through the slot 85 and drawn forward again to pull the pad down onto the upper edge of the support surface 84. The ~rictional ~orces applied against _1~02~
the opposite edges of the bent or folded sheet restricts its movement on the support surface 84~
In each embodiment the clamping action applied to the lowermost sheet extends to a position adjacent the adhesive bonded edge of the stack. The edge of the clamping member is thus one quarter of an inch to one inch from the edge of the stack opposite the abutment, when on the support surface.
~laving thus defined the present invention with reference to a preferred embodiment and several other embodiments, it is to be understood that other embodiments may be formed which do not depart from the spirit of the invention or the scope of the invention as claimed in the appended claims.

Detailed DescriEtion Referring now to Figure 1 there is illustrated a dispenser for a stack of notepaper, which dispen~er iB
generally designated by the reference numeral 11 and compri~e~ a main Erame 12 which may be molded and formed of joined parts to have an inner cavity 13 which may be filled with a sand or other heavy material to weight the dispenser~ The frame 12 has a bottom plate 14, a rear wall ~ 7~i22 15, opposed side walls 16 and 17, between which extend a generally planar support 20 for a stack of sheet material.
The support 20 extends from the front edge 21 of the holder to a generally vertical member 22, which woul~ be at one end of the stack 30 of sheet material and which, at its upper end, connects with the top 23 of the frame 12. The top 23 is shaped to form a cradle for a writing instrument and con-tinues to a well 24 shaped to receive a refill stack of notepaper, paper clips, or the upper sur~ace surrounding the well 2~ may support a nameplate, etc.
Supported for pivotal movement relative to the frame 12 is a platen or planar clampin~ plate 25 which is adapted ~or clamping the lowermost sheet 26 of a stack of sheets 30 onto the frame 12 of the holder~ As illustrated in Figures 1, 2 and 3, the plate 25 is adapted to pivot relative to the frame 12 and cooperates with the support 20 to firmly hol~ the lowermost sheet 26 in a position between the support 20 and the under side of the plate 25 to restrict movement of the sheet 26 with respect to the plane of the support 20. Extending upwardly from the ~orward end of the plate 25 is an abutment 31 which engages the edge of the lowermost sheets in the stack. The abutment 31 serves to restrict movement of a stack of sheets with respect to the platen 25 and support 20 during separation of the uppermost sheet in the stack. During the peeling or stripping movement when separating one sheet from the stack 30 the stack ~ends to li~t adjacent th~ edge where the sheets are joined, driving the stack ~orward or to apply a rotational or torsional force to be transmitte~ to the stack. These forces will be absorbed by the abutment and restrict movement of the pad with respect to the support and translates the forces to shear forces on the bands of adhesive joining the sheet~ to restrict separation of the stack ~rom the lowermost sheet.
Figure 3 illustrates in sectional view a stack 30 of sheet material on the dispenser 11 with the lowermost sheet 26 clamped between the platen 25 and the support ~;7~
surface 20. The clamp holds the lower sheet at a position adjacent the edge where the sheets are joined ~ogether as illustrated. This restricts a lifting and peeling force to be exerted between the lower sheet and the pad.
The pad or stack of sheet material illustrated comprises sheets of notepaper, approximately twenty pound bond paper, with each sheet coated along one edge with a readily repositionable pressure-sensitive adhesive. The adhesive is coated in a band about one-quarter to three quarters of an inch wide.
L~`igures 4, 5 and 6 illustrate the de~ail~ of the clamping plate and the support. The main frame 12 is provided at its forward end with a cut~away as illustrated at 34 to leave a narrow resilient finger 35 extendin~ along the lateral edge o~ the frame 12. Extending outward from the finger 35 is a fulcrum member 37 which defines the fulcrum for the pivoting clamping plate 25. Also extending outwardly from the lateral edge of the frame 12 is a stop member 39 which is spaced from the front edge of the frame 12.
~ s illustrated in Figures 4 and 5, the platen 25 is formed with depending side members 40 which cover the lateral edges of the frame 12 and the cover members 40 are provided with interior recesses cooperating with the fulcrum members 37 and the stop members 39 affording limited pivotal movement of the plate 25 and positioning of the plate 25.
As illustrated in Figures 2, 3 and 6, the under surface of the clamping plate 25 may be provided with transversely spaced pointed projections 45 which extend from the under surface of the plate 25 and cooperate with recesses 46 in the support member 20 such that upon insertion o~ the lowermo~t sheet 26 in the stack 30 the projection~ 45 will penetrate the sheet and hold the sheet securely against movement with respect to the support 20.
The clamping plate 25 could also be formed with a resilient detent similar to the stop ~ember 39 which would ~.~S7~
loc~ in a cooperating rece~s to frictionally hold the bottom sheet 26 securely between the support 20 and plate 25.
The dispenser 11 with the pivoted clamping plate 25 locks the lowermost sheet in position and holds the paper in a predetermined plane with respect to the support 20 and the plate 25 such that the user may write on the sheets of notepaper before separation from the stack down to the very last sheet without encountering an uneven writing surface beneath the next to the last sheet in the stack~
A second embodiment of the invention is illustrated in Figure 7 which illustrates a dispenser generally designated 51 comprising meAns defining a frame having means defining a support surface 52. Embedded in the support ~urface 52 and extending transversely thereof are a pair of permanent magnet~ 53 and 54 which are bars of a permanent magnetic material. A clamping plate 55 formed of a magnetic material may be inserted between the lowermost sheet 26 of a stack oE sheet material and the next adjacent sheet and the ~agnets 53 and 54 will clamp the sheet against the support 52 with sufficient force to hold the sheet 26 and the stack 30 against movernent with respect to the support surface. The magnetic plate 55 is provided with a raised and transversely extending abutment 57 which enga~3es one or more of the 3heets in the stack adjacent the front edge of the stack to hold the stack against movement.
~lso, the end 59 of the plate 55 may be bend downwardly acro~ the width of the plate to position the plate with respect to the front edge 60 of the holder, and position the opposite edge of the plate adjacent the adhe~ive band of the stack.
In a further embodiment of the invention as illu~trated in Figure 8 the dispenser 61 may have a frame formed of wood, stone, or other solid rnaterial and shaped to define a ~upport surface 62. ThG ~upport surface 62 may be formed on a surface recessed between edges 63 and 64 to ~762~
afford an improved artistic design for supporting the notepaper. In this embodiment the stack 30 of notepaper is positioned within the recessed area and the lowermost sheet in the stack is clamped between a clamping plate member 65 and the support surface 62 as illustrated in Figure 8~ The clamping plate 65 as shown more clearly in phantom view in Figure 8 and partially in section appears generally U-shaped comprises an upper support plate 66 that fits over the lowermost sheet in the stack and forms a support or wr.iting surface for the sheet material. Bent ~rom the surface of the plate 66 and extending upwardly therefrom is ~n abutment member 67 which engages the front edge of the sheets in the stack 30. The clamping plate 66 has a depending flange portion 68 which has a thickness equal to or slightly greater than the height of the front edge 69 of the holder 61 and has a lower locking plate 70 which fits beneath the holder 61 and the support surface 62 thereof.
In operation, as the clamping plate 67 is inserted over the lowermost sheet and moved rearwardly with respect to the recess in the holder 61, the normal resilience of the material forming the clamping plate 67 pinches or binds and frictionally holds the lowermost sheet of the stack firmly on the support 62. The abutment 67 in the meantime enqages the front edge of the stack to restrict any rotational movement of the stack with respect to the ~upport plate 650 A similar embodiment for a notepad holder and dispenser is illustrated in Figure 9r This holder, generally designated 71, formed of a solid material and generally wedge ~haped, ha~ an wpper support surface 72 for 3upporting the tack 30 of notepaper. A clamping plate Eor clamping the lowermost sheet in the stack to the holder 71 and in po~ition on the support ~urface 72 compriqes a clamping member 73 comprising a clamping plate 7~ adapted to extend over the lowermost sheet in the stack and to suppsrt the stack and clamp the lo:.armo~t sheet against the support surface 72. Extending upward from and cut from the ~2576~2 _9_ plate 7~ defining the support platen i,s a bent flange portion 75 defining an abutment member engaying the stack 30 along the lower ~ront edge of the sheet material.
The plate 74 is joined to generally U-shaped clamping members including sidewalls 76 which are trapazodial in shape to conform substantially to the shape of the ends 77 of the frame forming the holder 71. To these side members 76 are connected reversely turned flanges 78 serving to hold the plate 74 to the holder 71 when the support plate is slid up over the ~rame between lowermost sheet in the stack and the next sheet to a position near the coating of adhesive on the lowermost sheet to clamp the lower sheet in place.
Figure lO shows a further embodiment which comprises a holder for notepaper which is a unitary member without detachable pieces or pivotally joined pieces. In Figure lO the d;spenser 81 comprises a frame 82 which may be molded of a suitable material and provided with a support surface 8~ for ~upporting the stack 30 of note-paper. In this embodiment the lowermost sheet 26 is heldtightly to the support surface 84 by the sheet being directly sharply back upon itself and then reversely directed again to bind the sheet in a narrow slot 85 defined by ~enerally parallel wall members Eormed in the support plate 8~ at an acute angle to support plate 84 which thus clamps the sheet 26 against vertical movement with respect to the support 84~ An abutment 86 is forrned at the front edge of the holder and of the support surface 84 to engage the lowermost sheet~ in the stack to re~trict movement of the stack as the result o~ the lifting and peeling forceA applied to remove a sheet -from the ~tack of sheets 30.
To place the stack of sheets on the holder 81, the lowermo~t sheet is peeled from the ~orward edge of the pad and then directed through the slot 85 and drawn forward again to pull the pad down onto the upper edge of the support surface 84. The ~rictional ~orces applied against _1~02~
the opposite edges of the bent or folded sheet restricts its movement on the support surface 84~
In each embodiment the clamping action applied to the lowermost sheet extends to a position adjacent the adhesive bonded edge of the stack. The edge of the clamping member is thus one quarter of an inch to one inch from the edge of the stack opposite the abutment, when on the support surface.
~laving thus defined the present invention with reference to a preferred embodiment and several other embodiments, it is to be understood that other embodiments may be formed which do not depart from the spirit of the invention or the scope of the invention as claimed in the appended claims.
