JOGGLING TOOL,

Filed June: 11, 1943 Patented Nov. 28, 1944 I JOGGLINGTOIOL v @Qharles LrBeard, Lancaste Pa"- 1 I g 'p i gtio iun 11, 1943; Serial No. 490,471 iola m. (01. 1531-21) My invention relates to improvements in offset j dies, for forming oifset ordepressed portions in opposite endsjof pieces of metal of angular shape i or informpf strips, sothat a nurnber of such I pieces 1 may ,be secured together in overlapping "uniplanar arrangement. v I v p v Theprincipal object of theinvention is to providesuch a device having a minimum of structural parts requiring movement or. adjustment during the placing of work therein or removal ofthc same therefrom. j i

A furtherobject of the invention isgto provide an efficient die construction in. which flatstrips or right angularly bent. metal pieces can be readilyinserted and as ,readilyremoved therefrom.

A still further object is to provide a die construction adaptedto offset one end of a metal piece inserted in one side thereof and tooflset the other end of the piece when the latter is inserted in the opposite side thereof.

Objects and advantages, and features of invention in addition to those mentioned will appear from the constructiomand combination of parts hereinafter described and shown in the drawing,

wherein: l l

Figure 1 is a perspective view showing the dies in side by side relation assumed when used in a vise and showing in dotted and full lines an angle work strip before being joggled;

within the confines of the nuts, after the latter have been appliedfor a purpose hereinafter ex- The base or bottom die. member 3 is formed with spaced parallel and horizontally disposed threaded openings 8 at each side thereof. Bolts 9, extend into these openings andholda pair of sideplates II and H, in place. The plates II and I I. are formed along their inner lower ends with narrow flanges I I2 which serve to space the inner faces jof the plates a slight distance from the sides of the die member 3, thus forming nara purpose presently described.

The opposing upper and lower die members are respectively provided with workin faces I6 and I6 and adjacent recesses or cut away portions I1 and I1, these parts being staggered, that is, the working face I6 of the upper die memher 2 is opposed to thecut away portion I I of the lower die member 3, the working face I6 of v the latter being positioned opposite the recessed The conportion I! of the upper die member. struction thus described when placed in. a suitable vise 30, is readyto form ofi'sets in a piece of angle-shaped material I8, as illustrated in Figure 1. The jaws of the vise 30 are shown in side by side relation whereas it will be obvious that Figure 3 is a view similar to Figure 2, but showing the dies closed or in clamped position;

Figure 4 is a section taken on line 4-4 ofFigure 3;

Figure 5 is a section taken on line 4-4 of Figure 4 but with the dies reversed;

Figure 6 is a plan view of an angle strip joggled at both ends and showing straight angled strips overlapping these ends; and i Figure '7 is a detailed perspectiveshowin-g an angle strip joggled at both ends and showing a second angle strip placed in overlapping relation to one 'end of the joggled strip.

Referring more particularly to the drawing I denotes a die construction comprising what, for convenience, may be termed upper and lower rectangular die members 2 and 3 respectively. These members are formed with vertically disposedregistering openings 4, for loosely accomthese jaws could be vertically disposed and that the dieassembly could be placed in a conventional, press instead of a vise.

In practice one leg or web I9, of the angle work piece I8, which may be termed the horizontally disposed web, is placed between the die members. i

with its end overlying one side of the cut away or recessed portion I'I' of the lower die member, the other leg or web being snugly received within the side pocket I5, which for convenience i will be designated the right side pocket. The assembly is now placed in the vise and pressure in an obvious manner.

modating bolts 5. The bolts 5 are provided with threaded portions 6 at each end thereof to removably receive correspondingly threaded nuts I, and are somewhat longer than the combined applied to cause the working face I6 of the upper die member to force the end portion of web I9 downwardly into the recess I I of the lower die member 3, thus forming the desired offset 2|, The piece of material I8 is now removed and the opposite end of the web I9 inserted between the die members in overlying relation with respect to the other side of the cut away or recessed portion ll; of the lower die member, and the leg or web 20 snugly held in the left hand side pocket I5. The die members 2 and 3 are again clamped tightly torow open ended side pocketsl5 and I5', also for vise.

gether in the vise, and this end of the work is joggled at 22 in the same manner as the previously joggled end 2!. The depth of the recesses l'll1' is suchthat when the offset end of one piece of work is placed in overlapping relation with respect to theoffset end of a similar joggled piece, the connected sections will lie in a uniform plane. It will be obvious that the side plates H, l I can be adjusted within certain limits to increase the width of pockets l5l5' for the accommodation of work pieces formed from sheet metal of different thicknesses.

This is also true with respect to the spacing of the die members.

direction, with respect to the die members, ac-

cording to which end of the work piece is being offset or joggled, it being merely necessary to lift the upper die member away from the lower die member during these operations. Due to the fact that the pockets |.5-|5 are open at their ends they offer no obstacle to the insertion therein or removal of the" vertically disposed webs 20 therefrom.

It may be noted here that the upperside edges of the lower die member 3 are beveled at 25, to compensate for angle pieces of different radii, that is, eliminate the danger of disturbing the radius of the work piece when the j oggle is made.

While the die members have been described as being upper and lower members and the plates lI-l l as side plates it should be noted that these terms are relative and have been used rather loosely and as applying more particularlyto the parts priorto placing the die members in the When'the assembly is placed in a vise the jaws ofv which are; disposed in side by side relaunnecessary.

Having thus described'my invention: What I claim is:

' In an apparatus for deforming angle shaped strips of metal, a pair of opposed die members, means for securing said die members together for relative movement toward and away from each other, side plates adjustably secured to the sides of one of said die members, a flange extending along one edge of each of said side plates for maintaining them in spaced relation to said sides to form pockets, One of said pockets between said plates andsaid sides adapted to slidably receive one leg of an angle shaped strip when theother leg thereof is slidably inserted endwise' between the die members, at one side thereof, and the other pocket adapted. to receive said one leg when said other leg is slidably inserted between the die members at the other side thereof, said diemembers each having a working surface extending from side to side thereof and disposed in ofiset opposition to each other for joggling one or the other of the respective ends of said other leg upon relative movement of said die members toward each other according to which of theside pockets said one leg is inserted in.
