RENSSELAER REYNOLDS, OF STOCKPORT, .NEW YORK.

Letters Patent No.` 88,907, dated A11/ril 13, 1869.

mPROvlEilidENT-IN SASH-STOP AND LOCK The Schedule referred to in these Letters Patent and making To all whom 'it may concern:

Be it known that I, RnNssELAER RnYNoLDs, of Stockport, in the county of Columbia, and State of New York, have invented a new and improved Sash- Stop and Lock; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

The object of this invention is to provide for the retention of sliding window sashes at any desirable height when raised, and for. the locking of the same when down; and

The invention consists in a combined sliding wedge and falling tumbler, constructed and arranged for operating within the stile of a window-sash, vand acting against the jamb, or inner surface'of the window-casing, whereby the sash may he retained at any desirable height, by the action of the apparatus as a wedge when the sash is raised, and securely locked by the actionof the same as a tumbler whenthe sash is down. v

Figure 1 represents a side view of a sash and its casing provided with my improved stop and lock, and

Figure 2 represents the apparatus removed from the sash, and furnished with a different means of operating the same by hand.

Similar letters of reference indicate corresponding parts in both figures.

' C is a wedge, of an upward-tapering or inclined form, constructed of cast-iron, 0r other material, and `vertically arranged within a correspondingly tapering or inclined excavation or mortise, c, cut into the outer edge of the lower-portion of one of the stiles f, of the sash A. This wedge C is constructed tapering, or inclined upon its inner side," while its outer side remains straight i and even with the outer edge of the stile, but is so.

fitted within the correspondingly tapering or inclined mortise c, that an upward sliding of the said wedge within the-said mortise produces an outward lateral movement of the wedge, thereby causing its straight or perpendicular surface to project beyond the edge of the stile f, for a purpose hereinafter explained.

The said wedge C has provided upon its inner side, and near its lower extremity, a horizontal arm, b, which passes through the stile f, by means of a horizontal opening, o, near the lower extremity of the excavation c.

This arm b projects suiiciently. beyond the inner sash. The wedge being thus part of the :me

surface of the stile f for convenient manipulation of the same in operating th'e said wedge.

This wedge G also has provided upon the inner side of its lower extremity, a downward projection, d, upon which the said wedge C rests when not sustaining the supported upon its inner corner, its cen-tre of gravity-is thrown outside of or beyond the point of support, which gives the said wedge C a tumbler-like inclination to tilt over, and turning upon the projection d, as a pivot, to fall out of the mortise c, but is retained therein by the inner surface of the casing B, against which it rests.

q is an inverted notch, cut upon the inner surface of thecasing B, at a point opposite the location occupied by the wedge O, when the sash is down. When the sash is' brought to its lowest position, the said wedge C acting as a tumbler, falls by its own gravity into the notch g, and locks the sash.

When it is desired to open the window, the sash A is unlocked, by pressing down the lever b, which causes the wedge or tumbler C to turn upon the projection d as a fulcrum, thereby withdrawing the point of the said wedge, or tumbler O out of the notch g, when the sash may be easily raised.

When it is desired to retain the sashin a raised position, the wedge C is forced upward, by pressing upon the under side of the lever b, which engages the sides of the wedge C more closely with Athe adjacent surfaces of the stile f and casing B, thereby preventing the downward sliding of the sash. The same result is produced by retaining, or holding rm the arm of the wedge O, and releasing the sash, which, by dropping, securely fastens itself by sliding against the wedge.

Instead of the arm b, the apparatus may be furnished with a headed pin or bolt, on, passing through a slotted opening in the front sidelf the stile f, and screwedinto the wedge C at a point thereon most convenient for operating the same, as illustrated inl iig. 2.

What is here claimed, and desired to have secured by Letters Patent, isi The :wedge-shaped sash-stop C, constructed with a projection, al, on the inner edge of its but end, whereby it is made to lock automatically when the .sash is closed, substantially as shown and described.
