IHERON FROST, OF PIERMONT, NEW YORK..

Specification forming part of Letters Patent No. 136,232, dated February 25, 1 3.

To all whom yit may concern:

Be it known that I, THERON FROST, of Piermont, in the county ot' Rockland and State ot' New York, have invented a new and Improved Combined Sash Fastener and Tightener, and-I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure l is aperspective viewr from the rear side ot' the apparatus. Fig. 2 is a transverse vertical section, and 3 a top view ot the lower sash-plate.

Similar letters ot' reference in the accompan ying drawing denote the same parts.

The object ot' this invention is to combine a sash-lock and an anti-rattling device for windows in one simple, cheap, and convenient improved article of manufacture; and to this end the invention consists in the improved construction and combination of parts, substantially as I willnow proceed to describe.

In the drawing, A is the lower` rail of the upper sash, and B the upper rail of the lower sash. G is the plate for the upper sash, and D the plate for the lower one. The plate C is screwed directly to the upper side of the rail A, and has a vertical iiange, c, extending` upward from its inner edge and tlush with the inside ci the rail. To the outer side of theiiange c is secured, in any sufficient manner, a case, D', in which is pivoted a latch, E, which latch has a tooth, e, with an inclined upper edge, and extending inward through a slot in the Han ge c, and kept in this position by the weight of the latch, except when thrust backward. The plate D is screwed directly upon the upper side of the rail B, flush with the outside thereof, so that when either Athe upper sash, having been lowered, is raised, or the lower sash, having been raised, is lowered,- the inclined tooth e comes in contact with the edge of the plate D, and is moved back. At'- ter clearing the plate D the tooth e moves out again by its own weight over the plate, and thus locks the sashes. The tooth e is constructed with a shoulder, e, as shown in Fig. 2, which bears lagainst the tlan ge c, and takes from the pivot ofthe latch part of any strain that may be exerted upon the latter, either by pushing up on the lower sash or pulling down on the upper. F are lugs extending backward from the ends of the lower plate, and curving inward toward each other so as to form grooves -z of such width that the flange c lits them closely when both sashes are closed, so that these lugs preventrattling of the sashes.

A step, a, rising from the plate D ills the space between the latter and the-tooth e, and thus insures a tight lock.

The parts ot this device may be cast or struck out of any suitable metal.

Vhat I claim as new is- As an article of manufacture, the combined sash fastener and tightener herein described, consisting essentially of the plates C D, constructed, respectively, with the slotted flange c and lugs F, the case D', and the tooth E, constructed with the shoulder e and tooth e, all combined as described.

THERON FROST.
