SASH-FASTENER.

SPECIFICATIONforming part of Letters Patent No. 280,400, dated July 3, 1883. r

h Application filed May 152, 1883. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM EDWARD Ruins, of Arlington, in. the county of Middlesex, of the Commonwealth of Massachusetts, have invented a new and useful Improvement inRailway-Gar Window-Sash Fasteners; and I do hereby declare the same to be described in the following specification, and represented in the accompanying drawings, of which Figure 1 is a side elevation, and Fig. 2 a vertical section, of afastener of my improved kind as applied to a window sash and its frame, such sash and frame bein gsh own in part in such figures.

In the said drawings, A denotes one of the side bars of the sash-frame, while B is the next contiguous part of the windowframe.

My invention is to fasten the window-sash when closed, and to sustain it when raised to anyaltitude within the range of its vertical movement.

In the drawings, 0 denotes the case of the fastener, such case being proved with perforated flanges a a. to enable it to be fastened to the sash by means of screws going through such flanges andscrewed into the sash. This case, arranged nearthe outer edge of the sash, has within its lower part a bolt or latch, G, which extends out of the case in manner as shown, and is provided with a spring, H, to A knee-lever, I, having its longer arm projecting through a slot, 1), in the case, is fulcrumed within the case, (the fulcrum being shown at g,) and has its shorter arm extended into a notch, c, in the bolt. This bolt is to operate with the triangular projection 11 of the catch K, fastened to the window-frame in which the sash runs.

Above the bolt there is an eccentric, D, which projects out of the case and bears against the window-frame. This eccentric turns on a pivot, e, and is provided with an arm, j, that projects from it (the said eccentric) in manner as represented. A spring, F, arranged in the case and with respect to the said arm f in manner as shown, serves to depress the arm in order to force the eccentric against the windowframe. A lever, E, fulcruined in the case (the fulcrum being shown at 71.) and having its shorter arm curved upward and extending out of the case in manner as represented, has its shorter arm projected underneath and against the arm f of the eccentric.

A person, in order to raise the sash, is to seize the longer arms of the two levers E and I between the first and second fingers of his hand, placing the first one-via, the thumbon the lever E, and the second or index finger under the lever 1. Next he is to force the levers toward each other, or simply pull upward the lower one. This will cause the bolt G to be retracted and the sash to rise. Having elevated the sash to the desired altitude, he should release his hold of the levers, or the lower one, in which case the eccentric D, by its action against the frame in which the sash runs, will hold the sash in its position. In order to depress the sash, the longer arm of the lever E is to be forced downward, in which case the eccentric will be borne away from the frame and the sash may be lowered. In the descent of the sash the bolt G- will be borne against the triangular projection d, and by such will be forced backward until such bolt may pass below the said projection, which having taken place the bolt by its spring will be shot forward underneath the projection, and with such will lock the sash down.

I claim- The saslrfastener substantially as described, consisting of the case 0, bolt G, spring H, knee-lever I, eccentric D, the arm f, spring F, and lever E, arranged and adapted essentially and to operate as set forth.

WILLIAM EDXVARD RINES.
