mm M 1 5 5 J P r 0 T M m May 13, 1952 w. P. KESSLER SASH BALANCE Filed July 29, 1947 Patented May 13, 1952 UNITED STATES ATENT OFFICE SASH BALANCE Ward P. Kessler, near Bristol, Ind., assignor to Victor M. Langsett, Chicago, 111., as trustee Application July 29, 1947, Serial No. 764,402
6 Claims.
In double hung sash. it is common practice to usecounter-balances to offset the weight of the sash, and where spring balances are used, they are generally applied or installed without the perimeter of the window frame, for example, resting on the top member of the frame. This requires special treatment of the adjoining wall construction to accommodate the balances, and makes access difiicult after installation of the window has been completed. My invention relates to improved methods of installing a spring balance within the perimeter of the window frame, where the upper sash is fixed, directly over the sash track, resulting in reduction of friction and wear upon the balance tape, permitting ready access for repair or replacement, and making special treatment of the adjoining wall construction unnecessary. The window frame and sash are preferably made of formed metal or metal alloy by extrusion.
Further objects and advantages of the invention will be apparent from the following specification and the accompanying drawings, wherein a preferred embodiment of the invention has been shown and described.
In the drawings:
Figure 1 is a perspective view of the inner, upper-right hand corner of a formed metal window frame, with fixed upper sash, showing the spring balance in position and the face strip and sash guide and movable lower sash shown in part only.
Figure 2 is a side view of a portion of the face strip and sash guide showing the sash guide cut away to accommodate the balance.
Figure 3 is a perspective view of a cover plate used as another means of holding the balance in position.
The complete window has not been shown in the drawings, but from common knowledge and as indicated by the drawings, it is obvious that it consists of a frame, a fixed upper sash, and a vertically movable double hung lower sash.
Similar numerals refer to similar parts throughout the several views.
Referring to Figure 1 of the drawings, a formed main frame I with a plurality of angularly disposed walls, hereinafter called frame surfaces, including the frame surfaces 2, 3, 4, 5, B, I, 8 and 9, a plurality of obstrusions, including the obtrusions [0, ll, l2 and I3, and a plurality of channels, both L and U-shaped, including the L-shaped channels [4 and I5, is fabricated, preferably of extruded aluminum. The side and top members of the frame are joined at the corners, as at 22, by mechanical means, brazing or other suitable means. The glass 16 in the fixed upper sash formed by the main frame, abuts against the obtrusions I and II on the frame surface 6 and obtrusions I2 and i3 on the frame surface I, and is held in place and weather proofed by the putty H. A portion of the frame surface 4 is removed commencing with its end contacting the frame surface 3 for a distance substantially equal to the height of the balance, as shown at 18, forming the recess I 9. A standard spring balance 20 is inserted into this recess l9, one end side 2| abutting against the inner face of the frame surface 8, its bottom side 23 resting on the end 24 of the frame surface 4 and its sides 25 and 26, abutting against the inner faces of the frame surfaces 6 and 2, respectively, the balance tape 21 being attached to the upper right hand corner of the movable lower sash 43, by any suitable means, such as the screw 34. The balance tape 21 is hidden from view by the face strip 28. This formed face strip 28 has an inturned leg 29 serving as a guide for the lower sash and the lip 30, which conforms to and abuts against the channel l4 and the side 3! abuts against the inner face of the frame surface 2, where it is held in position by a plurality of screws, for example, the screw 32, passing through the hole 33 in the frame surface 2 and engaging a threaded receiver. The balance tape 21 extends downwardly behind the face strip 28 and between it and the sash guide 29. This face strip 28 and sash guide 29 extend upardly to the bottom 23 of the balance 20, which rests thereon. If desired, the face strip 28 may be continued upwardly, supporting and concealing the end side 35 of the balance 29 by removing a sufiicient portion of the guide 29 at 36 as shown in Figure 2 to accommodate the said balance 20. I prefer to conceal and further support the balance in position by using the angular cover plate 3'1 surfaces 6 and 5, respectively, and engaging threaded receivers. By use of this cover plate 31, the balance is wholly concealed, and is readily accessible for replacement or repair without removing the face strip 28 and sash guide 29. It is also apparent that the balance 20 1s contained, in part, in the recess I9, behind the glass It in the fixed upper sash and wholly within the perimeter of the window frame I and directly above the lower sash. While I have particularly described the invention in relation to the right upper hand balance application, it is obvious that similar application may be used in installing the upper left hand balance.
Also, while I have described in detail above the 3 application of the balance just below the upper frame surface I, my invention may be used in installing the balances in-simi1ar positions in the upper-sash below-the position described in,
detail in, orderto shorten the len th of thebalance tape. For example, in windows having the greater part thereof in the form of a fixed upper sash with a movable lower sash of lesser height, I have found it to be an advantage-toinstall the balance by means oftmrinventio iz; within the frame as described atza'distanceabove and substantially equal to the height: of the-mQv-.- able lower sash, thereby permitting a full vent opening upon raising the movable sash and'reducing the length of the balance tape required to suspend-said sash.
Changes maybemade in the form; construc' tion' and arrangement of *the parts without rde parting from the spirit of the-invention or sac; rificingeany of: its advantages,.- and-=the right is herebyereserved to make all such changes. as
fairly fall within the scope of the followingclaims.
