OF BELLAIRE, OHIO.

SASH-HOLDER.

SPECIFICATION forming part of Letters Patent N 0. 452,463, dated May 19, 1891.

Application filed March 3, 1891.

To all whom it may concern.- 7

Be it known that 1, CHARLES S. APPLE, a citizen of the United States, residing at Bellaire, in the county of Belmont and State of Ohio, have invented certain new and useful Improvements in Sash-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to various new and useful improvementsin sash-fasteners, by the use of which windows may be securely locked either in an elevated position when opened wholly or partly or in a lowered position The principal objects of my invention are to provide and produce asash-fastener which will firmly secure a window in a lowered or elevated position, which will be simple in construction, effective in use, cheap to manufacture, and capable of being easily and quickly placed in position.

To this end the invention consists, generally, of a right-angled plate, the vertical arm of which being intended to fit in the space between the sash and tile sash-frame, and a lever pivoted therein and extending a short distance above the horizontal arm of the plate for engagement with the under side of the sash, and provided with a friction-plate at its lower end for engaging with the side of the sash-frame, all as will be more fully hereinafter described and claimed.

For a better comprehension of the invention attention is directed to the accompanying drawings, forming a part of the specification, and in which Figure 1 is a perspective view of the invention; Fig. 2, a side elevation showing the fastener in position for holding the window in an elevated position, and Fig. 3 an elevation showing the fastener in position for locking the window when closed.

In all the above views corresponding parts are designated by the same letters of reference.

A is the right-angled plate, which has been before referred to. This plate is preferably made of sheet metal, which may be stamped or bent into its proper position, but it may be made of cast metal, if desired.

Serial No. 383,557. (No model.)

Bis a curved lever of the general shape shown, and which is provided with a pivoting pin a. This curvedlever is pivoted at the forward end to the plate A, preferably by providing the plate with two bifurcated portions, which are bent over the pivoting-pin a, as shown; but it may be understood that it may be pivoted in place in any other way. The curvedlever B is provided directly above the horizontal portion of the plate A with a small lug b, which bears upon the plate, and which will retain the lever B in a'normallyinclined position, so as to engage with the sash-frame, as will be presently described.

The lower end of the lever B is provided with a fiat bearing portion which bears upon the sash-frame. If desired, this bearing-face a may be suitably roughened, so as to engage more firmly with the sash-frame, or it may be provided with a rubber bearing-face for the same purpose; but I have found that it. is not necessary, and with a perfectly smooth bearingsurface every requirement is answered.

The operation of the deviceis substantially as follows: hen it is desired to hold the window in an elevated position,the window is first elevated to the desired height and the plate A is inserted in position with its vertical arm in place between the sash and the sashframe. The window upon being allowed to descend will bear upon the upper portion of the plate A and cause the lower portion of the bearing-face e to engage with the sashframe. In this way the lever B will be forced into an almost horizontal position, so asto constitute a toggle-joint, which will effectually prevent the further descent of the window. hen it is desired to lower the window, it is first elevated so as to allow the lever B to become disengaged from the sashframe, and the entire fastening is then redow will be effectually held in an elevated position and the smooth bearing-face will not deface or injure the sash-frame in any way. When it is desired to lock the window in a lowered position, the vertical part of the plate A is inserted in place between the top of the sash and the sash-frame with the device in an inverted position, as shown in Fig. 8. It will now be, seen that when an attempt is moved from its place. In this way the win-- ICO right-angled frameA and a curved lever B, pivoted therein and provided with the lug b, and with a flat bearing-faee c at its lower end, all combined and aranged substantially as set forth.
