Specification of Letters Patent. Patented May 24, 1910.

Application filed September 3, 1909. Serial No. 516,156.

, Fasteners and Lifters, ofwhieh the follow ing is a specification.

This invention is a combination sash fastener and lifter, and has for its object to provide an improved device of the kind which will be attached to a winddw sash and which can be used to lift the "same, and simultaneously engage or disengage. a locking bolt which will fasten the sash in position at the desired height. By providing a combined lifter and lock the use of two separate devices is avoided.

The invention is illustrated in the accompanying drawings in which Figure 1 is a front elevation of a window sash and frame provided with the device; Fig. 2 is a front elevation of the device with the front plate of its casing removed; Fig. 3 is a cross section on the line 33 of Fig. 2.

Referring specifically to the drawings, 6 indicates the lower rail of a window sash, which slide in a casing 7, the stile or jamb of the casing being provided with a rack or series of holes as indicated at 8. The attachment hereinafter described may be fastened to the front of the sash rail, but will preferably be sunken in a recess therein, so as to bring the face plate flush with the front of the rail.

The parts comprise a casing 9 made of sheet metal or the like and having a face plate 10 in which a recess 11 is formed to receive the fingers of the operator. This recess is conveniently formed by cutting out a section of the plate along the top and two sides, forming a. flap 12 which is bent back and serves to guide the fingers to the bolt operating device. The edge of the opening is rounded at the top, as indicated at 13, so as to avoid cutting or injuring the hand of the operator when the sash is lifted.

A bolt 14 is arranged to slide in a transverse bore in the bottom rail of the sash.

Or, if the device is applied to the front of the sash, suitable guides for the bolt will be provided. The outer end of the bolt is arranged to engage the rack 8 when it is advanced. At its inner end it has an eye 15 which receives the lower end of the depending arm 16 of a bent or bell crank lever the upper arm of which is flattened to form a' finger piece 17, said arm being located in the upper art of the casing, and the lever is pivote "at 18. A spring 19, attached to the top of the casing, bears on the arm 17 and normally pushes the same down to hold the bolt in engagement with the rack. The upper edge of the flap 12 forms a stop for the lever.

In the operation of the device, when the hand is inserted in the opening, 11, the ends of the fingers of the operator will press upwardly against the finger piece 17 and when the pressure is applied the lever will turn on its pivot, thereby drawing the bolt 14 inwardly, or retracting the same from the rack, and further pressure will lift the sash to the desired position; and when the pressure is released the spring will advance the bolt and cause the end thereof to engage the rack and thereby hold the sash in position. The bolt thus acts to lock the sash in any position desired, and the whole forms a sash lifter and fastener capable of manipulation with one hand. To lower the sash the fingers are pressed against the piece 17, with the thumb against the top of the casing or sash rail, in order to release the bolt, which is thus held released while the sash is lowered. A window may be left open with comparative safety, because the operating lever is concealed in the upper part of the casing and manipulation thereof from the outside of the window would be very diflicult.

I claim:

A combined window-sash lifter and fastener, comprising a casing fixed to the sash rail and having a face plate made of sheet metal with a flap cut therein forming a hand hole in the front thereof, said flap being bent backwardly from the lower edge of the hole to form a guide for the fingers,

a bent lever located in the casing and pivcasing, and a spring tending to advance the oted thereto and having a horizontal arm bolt. 10
