SAsH-FASTENER.

SPECIFICATION forming part of Letters Patent No.` 295,530, dated March 25, 188e. Application filed January 4, 1884. (No model.)

To all whom t may concern: n

Be it known that I, SAMUEL FARQUHAR, of Newton, in the county of Middlesex and State of Massachusetts, have invented an Improved Sash-Fastener, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in whic Figure 1 is a perspective view of a portion of a window-frame and its sashes with my im` proved fastening device in .its locking position applied thereto. Fig. 2 is a perspective view" ofthe rear of my fastening device as seen from the pulleystile into which it is fitted. Fig. 3

Vrepresents a portion of the upper sash, with dotted recesses therein for the fastening-bolt tional elevation. Fig. 5 is ahorizontal section.

My present invention relates to that class of sashffasteners located within the pulley-stile, and has for its object to prevent the sashes from being clandestinely opened from the outside; and this invention consists in a springactuated or weighted lever pivoted within a frame or casing let in flush with the stile, in combination with a bolt connected with the top of the lever by an arm pivoted to lugs projecting from the casing, the lower end or heel of the lever having anunyielding bearing on the top ofthe contiguous side ofthe lower sash,

Y or upon a plate secured thereto, the correspending side of the upper sash being provided with one or more recesses for the reception of the bolt when the lever is in its locking position, the said fastening being simple and durable, and possessing the ability to resist any attempts to pry up the lower sash or force down the upper sash from the outside.

To enable others skilled in the art to understand and apply my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, A represents a portion of a window-frame; B, the upper sash; C, the lower sash; D, the pulley-stile, and E-thepart- Ving-bead, all of which are of well-known con` struction.`

G is a metal frame or casing, composed of a vertical portion, a, and a horizontal portion, b. Between the sides "of the vertical portion a is pivoted, at c, a lever, H, (of the form seen in Fig. 4,) having a slot, d, formed through its tal bolt, L, which passes through a guide, k,

formed in the outer end of the portion b of the casing, and enters one of a series of cylindrical recesses, Z, formed in the contiguous face of the upper sash, (see Fig. 5,) the said bolt being pressed into said recess by the action of a spring, m, Fig. 4, whose upper end is securedat a to the back of the lever, and whose lower end is free to slide against a stop-pin, p, eX- tending between the sides of the vertical portion of the casing, by which construction the lower end of the lever ispressed 'in the direction of the arrow, with its heel bearing on a plate, r, set in flush with the top of the lower sash, said lever being in its normal or locking position, Figs. l and 4, until pressure is ap- `plied upon its lower end against the resistance of the spring when the bottom of the lever is moved in fiush with the inner face of' its metallic casing, in which position either sash iS free to be moved. When the upper sash is lowered sufficiently to bring one of its recessesl in line with the bolt, the compression of the spring m is relaxed, the heel of the lever'is pressed by the expansionl of the spring inward upon the bearing-plate r, and, through the connections described, the bolt is caused to enter the recess in line, and the two sashes are securely locked, the said locking device being effectual in resisting any attemptsto raise the lower sash or lower the upper sash from the outside. When the upper sash is to be lowered, so as to secure the ventilation of the apartment, it is simply necessary to press in the lower end of the lever and lower the upper sash until another of its recesses is brought in line with the bolt, when the latter is pressed therein, and the upper sash locked in this position, the lower sash being simultaneouslylocked by the return of the heel of the lever upon its bearingplate r.

By pivoting the lever Gr and arm I-within' IOC the casing, the several parts constituting the device are always at hand, and may beremoved and applied at one operation. The spring m may be dispensed with 5 but in such case the location of the pivot c must be changed, so that l tion b of the easing A, and the bolt L, having the Weight of the upper end of the lever Will a slot, i, in its outer end, in combination With cause the lower end to project out of its easing over the lower sash; lout I prefer the construe- 5 tion rst described.

I claim- The Within-described sash-fastener designed to be looated in the pulley-stile, consisting of the lever H, pivoted to the vertical portion a 1o of the easing A, and having a slot, d, in its upper end, the connecting-arm I, pivoted t0 lugs 7L h, projecting` from the horizontal porthe upper sash, B, provided with recesses Z, i 5 and the lower sash, G, all constructed and arranged as Set forth.

Vitness my hand this 28th day of December, 1888. f l
