WINDOW-FRAME A-ND WINDOW-SASH.

SPECIFICATIQN forming part of Letters Patent N o. 683,077, dated September 24, 1901.

Application filed August 24, 1899. Serial No. 728.326. (No model.)

To all whom it may concern; A

Be it known that I, HENRY C. SMITH, a citizen of the'United States, and a resident of Somerville, in the county of Middlesex' and State of Massachusetts, have invented a new and useful Improvement in Window-Frames' and Wiudow-Sashes, of which the following is a full, clear, and exact description, reference being had to the accompanying draw- Io ings, forming apart of this specification, in

explaining its nature.

The invention is an improvement upon that described in my application for Letters Patent of the United States (Case A) ezgeclxted of even date herewith; and it consists in a modification of the window-sashes in that one or both of the side rails of the sash is or are made in two longitudinal sections, the inner of which is united to the top and bottom rails 2o of the sash and the' outer of which is de- 3o site width to fill the spaces between the stop- 4o sections of the frame.

beads by means of separate pieces, which are then united or joined to the remainderof the sash by being slid vertically upon the incomplete edges thereof. These two sections of the side rails are so formed as to interlock, and this construction of the window-sash permits the side sections of the window-frame to be constructed with permanent stop-beads, which are integral with the rest of the side The side sections of the frame in all other respects are like those described in my said pending application.

In the drawings, Figure 1 is a vertical section of my improved window frame and sash. Fig. 2 is a vertical section on the line 2 2 of Fig. 3. Fig. 3 is a horizontal section on the line 3 3 of Fig. 2. Fig. 4 is avertical section of the weight-adjusting device. Fig. 5 is a detail perspective view of the frame. Fig. 6

5o is a detail perspective of a portion of the rail. Fig. 7 is a modification to which reference will hereinafter be made.

dow-frame, B the upper window-sash, and C the lower window-sash. The vframe is made 'of sheet metal and comprises the side sections d a', the sill-section 0,2, and head-section da. The sill and head sections are each made ot' one piece ot' sheet metal, substantially as describedV in my said application, and they are joined at each end with the lower and upper ends of the side sections. Each side section is also preferably made of one piece of sheet metal and varies from the side section of said application in thatit is provided with two additional integral stop beads-namely, the outer stop-bead a4 and the inner stop-bead a5. 'lhese are formed integral with the plate from which the section is made by bending. As these beads are made before the frame is set and are not removable, I have constructed the side rail of each window-sash in two parts, the inner of which parts is attached to the top and bottom rails of the sash and the outer of which parts is detachable and attachable. This provides a sash which can be narrowed for insertion into the frame and can then be widened by the addition of the detachable side sash-sections.

In the drawings,B represents one of the side rails of the sash, and b is the section of said side rail which is rigidly secured to the upper and lower rails of the sash.

b2 is the independent attachable section of the side rail. Y

The section l) preferably is made of two pieces of sheet metal-namely, a piece which is shaped to form the part b3 and thev piece which is shaped to form the glass-retainer b4. The piece b3 forms the sides b5 bs, the inner edge 57, and the outer edge bs. The inner edge has the shoulder b9, against which the glass is set, and a section blo of a lock for the retainer b4. The outer edge bs of the section is formed of the two ends of the piece, which preferably are bent inward to form the beveled section b, then outward parallel with each other, and then returned upon themselves to form part-s Z112 of a joint by which the detachable section b2 of the sash-rail is secured to it.

The detachable section b2 of the side rail A is made of one piece of sheet metal shaped to provide the continuous edge face 513, the innor and outer side sections b1* Z915, and the inner sections bw. These sections are shaped to abut against the parts bil--that is, they are formed outward at an obtuse angle to the sides and are substantially parallel with the diagonal faces of the section b. They are also formed to interlock with the locking parts of the section b by having their ends b turned inward parallel with each other. (See Fig. 6.) The parts of the locking-joints are thus so formed that the detachablesection b2 may be united to the section b by being-moved vertically from above or below in relation to it, the locking ends L17 of the detachable section being thus interlocked with the locking portions of the section b.

The glass-retainer b4 is made from asingle sheet of metal, has thejoint-section D18, which interlocks with the joint b1 of the section b, the diagonal bracing edge b1, and hemmed outer edge Z920. It is bolted by the bolts b21 to the parts h. The mullion or center railD of the sash I prefer to make as represented in Fig. 3. l

E representsa sash-retaining spring united to the sash by fusible metal bearing against the casing and `designed to help balance a heavier inner sash against a lighter outer ysash and also to release both sashes in case of heat from a fire sufficient to melt the attaching-solder. I do not, however, claim this spring and its use here, as I have described andclaimed the same in the application above referred to.

l prefer that the sashes be hung as described in saidapplication-that is, that the sashes be connected by a tape or wire cord F running from the top of one over a fixed pulleyfaud to the top of the other. To permit both sashes to be closed, it is necessary that the connecting tape or cord should be of the proper length and have no slack or be too short, and as it would be difiicult tohang the sashes in a manner to provide this proper length without some means for the `adjustment of the length of the tape or cord I have provided one of the sashes with a cord or tape adjusting device consisting of alever G, to the outer end g of which the cord is attached, and which lever is fulcrumed at g and is adjusted to raise or lower the said outer end g by an adjusting-screw g2, accessible from the top of the sash and screwing through a threaded hole in the end g3 of the lever. By turning this screw the end g of the lever is raised or lowered with respect to the top of the sash, and the sash tape or cord is lengthened or shortened thereby.

To hold the detachable section Z22 of the side rail of the sash in place, I may use any locking device, and I have represented an an glo-iron I-I at the upper corners of the sash, which has a horizontal section extending over both ends of the two sections of the side rail onto the top rail, if desired, and a vertical section which extends along the outer or inner surface of the detachable section and which is united to the side sections by rivets or bolts. In lieu of adjusting the j end or ends of the sash tape orA cord the pulley over which it runs may be made vertically adjustable.

In practice, the detachable sectionsA of the sash being first set into the proper pair of r grooves in the side frames-for example, the 75 grooves a-the sash is then moved vertically so that the interlocking ends b slide into their appropriate grooves. It will thus be seen that the window-frame itself does not have to be taken apart in order to receive the window-sash, as is the case with the ordinary window frame and sash.

In Fig. 7 I have represented the windowsashes as counterbalanccd'by weights in the ordinary way, and when they are so 'hung I prefer to employ a metal window-frame having weight-holding metal cavities and to make engagement between the sashes and the weights in the cavities in the usual way.

The window-frame when so constructed 9o `may be made substantially in accordance with that described in my application for Letters Patent of the United States, filed May 31,1399, Serial No.7l8,794, and allowed August 7,1899.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United Statesl. A window-sash having a side rail made `in two longitudinal sections, one of each sections forming a permanent part of said sash, roo the other of which is detachably secured as described, said sections having a bearing against each other along their entire length whereby one section of said sash is rendered incapable of any swinging movement relative to the other and both sections are adapted to be moved together vertically in the windowa frame, as and for the purposes described.

2. A metallic window-sash having a side rail in two sections, one of which forms a 11o permanent part of the window-sash :and is formed to interlock with a portion of the other section of the rail, said other section of the rail being detachable from the iirst-'named section and having interlocking sections to engage the interlocking parts of the permanent section of the rail, the interlocking sections of the said removable section engaging the interlocking sections of the Iixed section by a longitudinal sliding movement of one upon the other.

3. The combination of a metallic Window; frame having permanent front and back stop beads and a permanent central stopbead, a metallic window-sash having a side rail in two parts or sections the outer of which is removable from the inner to narrow the same and is attached to the inner after the sash has been placed in position in the frame by a vertical movement with respect thereto, whereby the sash is made to ll between two of the beads.

4. The combination of awindow-frame hav-V ing permanent front and back stop-beads and 5. The combination in a metallic Windowsash of the side rail made in two sections or parts one of which is detachable by a longitudinal movement with respect to the other and attachable in the same way thereto, and means for locking the two sections of the sash together when in engagement.
