Sash weight

Application filed December 17, 1929. Serial No. 414,765.

In the cutting, shearing, punching and forming of metal sheets and bars, particularly those of the heavier grades, there is considerable waste material, and one of the ob5 jects of the present invention is to provide a means for successfully using some of this waste and at. the same time provide a counterweight for window sash and the like, which is not only practicable, but is actually advanm tageous over the well-known cast weights in that it is not apt to be broken and is relatively heavy in comparison to its size, or bulk.

A further and important object is to provide a novel structure in which portions or 1ύ sections can be readily removed to vary the weight. · i ί

While the invention is primarily intended for use in counterweighting window sash, it is obviously not restricted to such employ20 ment.

In the accompanying drawings:

Figure 1 is a perspective view of a form of the invention that is at present considered preferable.

Figure 2 is a side elevation with the upper portion in section, on the line 2—2 of Figure 1. ,

Figure 3 is a sectional view on the line 3—3 of Figure 2.

The invention as disclosed consists of a stack of metal plates 4, which are shown as rectangular and of equal size. These plates may be cut from waste or scrap steel bars and are therefore relatively heavy. Though in35 dependent pieces, they are permanently held together by lines 5 of electric welding, the welding tools being passed along the opposite sides of the stack and causing the metal of the different plates to flow together and unite in 40 a manner well understood. The topmost sheet of the pile, designated 4α, is provided with an opening 6 that is preferably elongated, and the plate below it, designated 45, is provided with a slot 7 . alined with the opening 45 or slot 6, but longer than the same so as to extend beneath the plate 4α at the opposite ends of the opening 6, as clearly shown in Figure 2. This affords an anchoring means for a hanger eye member which is preferably in the form of a staple 8, the closed or looped end of which projects above the stack and has its shanks 9 extending downwardly through the opening 6 with the terminals 10 offset and lying in the end portions of the slot 7 beneath the plate 4α. A simple, but very effective eye 55 is therefore provided in which the cable or other hanger can be engaged.

A trim and very compact counterweight is thus provided, the weight of which is relatively great for its size, making it particu- 60 larly useful· for metallic sash in metal window-frames. The structure furthermore permits a Variation in weight. That is to say, by employing a cold chisel and hammer, one or more of the lowermost plates can be removed 65 by cutting the welded portions.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without fur- 70 ther description and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the ad van- 75 tages of the invention.
