SASH-LGCK.

Toall whom it may concern: a Be it known that I, MICHAEL SMoLnN- SKY, citizen of the. United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful -Im rovements in Sash- Locks, of which the ollowing-is a specification.

This invention relates to sash holders or.

locks of that type which are provided with members engagmg the side frame of the window casing, and has for its object to provide an improved device of the kind stated, which is normally engaged with the frame to hold the sash in locked position, and which can be released when desired to raise or lower the sash.

The invention is illustrated in the accompanying drawings in which Figure 1 is a front elevation of a sash provided with the devices, parts being removed. Fig.2 is a top view thereof, the sash and casing being shown in section. Fig. 3 is a detail showing the parts in unlocked position. Figs. ,4 and 5 are respectively front and top views of a modification.

Referring specifically to the drawings, 7 indicates pivoted friction members, one of which is located at each end of the lower rail of the sash 10, in position to bear against the side frame 11 of the casing and hold the sash by wedge and friction contact with the casing. This wedge member is pivoted at -13, in a suitable recess formed in the bottom rail of the sash.

6 is a cam lever pivoted at 12, with its toe in position to bear against inner side of the member 7 and press the same against the casing. The inner end of the lever 6 is connected by a link 14 to a rocking plate or bell crank lever 15 which is pivoted at 16 to the lower rail. The rocking plate is connected by a pivoted link 17 to a rod 18 which is slidable lengthwise in a suitable guide 19 on the rail. The inner ends of the rods 18 are connected by pivoted links 19 to a lever 20 which is fulcrumed at 21 on the rail, and this lever is connected by a pivoted link 22 to a finger piece 23 which is slidable up and down, being guided in a slot 24in a plate 25 on the rail, and from which projects a fixed finger or lifting piece 26 at the front of the rail. A. spring 28 presses on the rocking plate or lever 15, and tends to swing the same to the position shown in Fig. 1, in which position the toe Specification of Letters Patent.

of the lever 6- presses the member: 7 to friction or binding contact with. the window casing. T e link 14 has a toe29 arranged to stop aga 'nst a projection 30 on theinner side; of the member 7 when said member 1s withdrawnfrom contact with the casing. The part 30 projects through an opening in the wedge late 7, from a plate 31 which fits' aga nst t e outer side of the plate 7, and whlch 1s provided with a spring pin 32 which tends to swing the plate 7 inwardly when the parts are released.

The operation is as follows :The spring 28 normally holds the plate 7 in friction contact with the window casing, as above described. To release the same, the finger plece 23 is'pressed down. This turns the lever 20 onits pivot 21, and by means of the connections described, the cam lever '6 is turned, withdrawing its toe from the plate "7 which is then lifted out of contact with the window casing by the spring pin 32, thereby releasing 'the sash so that it can be ralsed or lowered. The same action takes place at both sides of the sash. When the finger piece 23 is released, the springs 28 throw both members 7 outwardly into contact with the casing.

In the modified form shown in Figs. 4 and 5, the parts 6 and 7 operate in the same way.

but the lever 6 is connected by alink 40 to a lifting member 41 which has an eye 42 at its upper end, slidable on a pin 43, with a coiled spring 44 around the pin and tending to lift the member 41 and'throw the toe of the lever 6 against the plate 7. The members 41 and 42 may be pressed down by a sliding finger piece 45 which moves up and down on the pin 43, and when pressed down, it turns the lever 6 on its pivot and releases the plate 7. In this construction, one

of the devices is located at each end of the rail, with an operating member 45 for each,

so that both hands are used in manipulating the devices.

. I claim 1. A sash holder comprisin a pivoted plate mounted on the sash an adapted to engage the window casing, a spring-pressed lever pivoted on the sash and bearing against the inner side of said plate to press the same outwardly against the casing, and a finger piece mounted on the sash and connected to said lever and operative to release the same.

2. A sash holder comprising a friction plate pivoted at the side of the sash and adapted to bear against the window casing when swung outwardly, a cam lever pivoted to the sash and hearing at one end against the inner side of the plate and acting to swing the same outwardly against the sash, a finger piece slidable up and down on the sash and operatively connected to the other end of the lever to release the samefrom the plate, and a spring bearing on one of said parts and tending to hold the plate in contact with the casing.

3. A sash holder comprising a pivoted plate mounted on the sash and adapted to engage the window casing, a cam lever bearing against the plate and adapted to press the same against the Window casing, a rock plate connected to the lever, a longitudinally movable rod mounted on the sash rail and connected to said rock plate to turn the same, a finger piece mounted on the rail of the sash and connected to said rod. and operating to shift the same to release the first mentioned Slate from the casing, and a spring norma y holding said plate in contact with the casing.

4. A sash holder comprising a pair of pivoted friction plates located at opposite ends of the sash rail and ada ted to en gage opposite sides of the win ow casing, a cam lever bearing against each friction plate, a spring acting on each lever and tending to turn the same to press the plates into contact with the casing, a shiftahle rod mounted on the rail and connected to each lever, and a vertically movable finger piece operatively connected to the inner ends of the rods and acting to withdraw the same 7 and release the friction plates, In testimony whereof, I do hereby aflia my signature in presence of two witnesses.
