JOHN wEsLEY COOPER, OF NEW YORK, N. Y.

WINDOW.

SPECIFICATION forming part of Letters Patent No. 480,806, dated August 16, 1892.

Application filed August 311 1891.

To all whom it may concern.-

Be it known that 1, JOHN WESLEY COOPER, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in WVindoWs; and I do declare the following to be afull, clear, and exact description of the invention, such as, will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to windows.

The purpose of the invention is to pivot the sash to counterbalanced slides in the frame, whereby the sash can be readily raised and lowered after the manner of counterbalanced sashes and can be turned on pivots to facilitate the cleaning of the glass, thereby obviating the danger attendant upon mounting the window-sill to reach the outside of the glass for any purpose, whether for cleaning, painting, replacing broken lights, or for any purpose whatsoever.

A further purpose of the invention is to preserve tight joints between the edges of the sash and the said counterbalanced slides to exclude wet, dust, and wind.

The improvement consists of the novel features and the peculiar construction and combination of the parts, which will be hereinafter more fully described and claimed, and which are shown in the annexed drawings, in which Figure 1 is a front view of a Window embodying my invention, parts being broken away. Fig. 2 is a section of the frame on the line X X of Fig. 1, looking to the right, showing the upper and the lower sashes turned on their pivots. Fig. 3 is a cross-section of one side of the frame and thetwo sashes. Fig. 4. is an edge view of the sash. Fig. 5 is an edge view of the counterbalanced slide. Fig. 6 is a cross-section .of a side stile of the sash and the counterbalanced slide at the pivotal-point, showing the relative location of the pivot and the pivot-receiving plate.

The upper and the lowersashes A and B are similarly constructed. Hence a detailed description of the one will sufice for both. The meeting edges of the counterbalanced slides and the side stiles of the sashes are constructed substantially as shown in Figs. 3, 4.,

Serial No. 404,313. (No model.)

and 5. It will be understood that each sash will be provided with two counterbalanced slides, one for each side, and that the outer edges of the side stiles of the sash will be similarly constructed. The pivot G is headed and screwed into the counterbalanced slide and is braced by the plate g, which is let into the said slide, so as to come flush with the edge thereof, and which is centrally apertured to receive the said pivot. The plate F, let into and secured to the edge of the side stile C, 1s provided with slot f, which flares sllghtly. The wood immediately beneath the plate F and bordering on the edges of the slot f is cut away sufficiently to give clearance for the head of the pivot. The counterbalanced slide is rabbeted on opposite sides from near the pivot toward each end, the rabbets extending to a line midway between the sides of the sald counterbalanced slide. The side stile of the sash is correspondingly rabbeted on its opposite edges, so that when the counterbalanced slide and the sash are together a close Joint is formed between them, as shown in Fig. 3.

The meeting-line of the rabbeted edges of the counterbalanced slide and the said stile is oblique, as most clearly shown in Fig. 3, thereby insuring a close joint and preventing any binding until the parts are together.

The window-head is higher on the inside than on the outside to permit the top rail of the upper sash to clear the bottom rail of the lower sash when the lower sash is at the highest position and the top sash is at the lowest position, so that the said top sash may be turned on its pivots without interference with the lower sash in the said reversed positions. The sashes are held to the said counterbalanced slides by suitable catches P, which are mortised into the side stiles of the sash. The preferred form of catch is clearly outlined in Fig. 1 and comprises a base-plate M, elbowlever N, pivoted at the elbow, and spring 0.

The sash can be moved up and down in the frame in the usual manner, and to reach them for cleaning, replacing broken glass, or for any other purposes the catches P are operated and the sash turned on their pivots, as shown in Fig. 2. Obviously when the sash are in the position shown in Fig. 2, they can be removed by moving them endwise in the proper direction to disengage the slotted plates F from the pivots. It will be understood that the plate g and pivot G may be integrally formed; butit is preferred to have the pivot adjustably connected with the said counterbalanced slide, in that means is afforded to allow for variations in mechanical construction, so as to insure a close joint between the sash and the counterbalanced slides without binding.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a window, the combination, with independent counterbalanced slides and pivots projected from the opposing sides of the said slides midway of the ends thereof, of a sash and plates F, secured to the sides of the sash and having slots f opening downward through the lower ends of the said plates, substantially as set forth, whereby the sash is pivotally supported and adapted to be removably connected with the said slides.

2. In a window, the combination, with a sash and independent counterbalanced slides, of

plates F, secured to the sides of the sash and secured to the said slides and adapted to enter the said slots f and having heads to overlap the sides of the slots to lock the sash and slides together, substantially as described.

3. In a window, the combination, with the independent counterbalanced slides and the sash pivotally connected together midway of their ends, the meeting edges of the said slides and the side stiles of the sash being rabbeted on opposite edges from a point near the pivotal connection between the said slides and sash, of plates F, secured to the sash and having slots f opening downward, headed pivots G, adjustably connected with the said slides, and plates g to brace the said pivots, substantially as set forth.

In testimony whereof I atfix in y signature in presence of two witnesses.

JOHN WESLEY COOPER.
