SASH-LOCK.

SPECIFICATION forming part of Letters Patent No. 762,595, dated June 14, 1904.

A lication filed December 12, 1903. Serial No. 184,901. (No model.)

citizen of the United States, residing in the city-and county of San Francisco and State of California, have invented new and useful Improvements in Sash-Locks, of which the following is a specification.

My invention relates to an improvedappliance for securely locking together the upper and lower sashes of windows.

Its object is to provide a cheap, simple, du-

rable, and attractive device which may be attached to either side of any sash to lock two sashes together and prevent their rattling and which will' permit the upper and lower sashes to be locked together, either when closed or when opened, and when so locked together in any desired open position the size of the opening cannot be enlarged by any one on the outside.

It consists of the parts and the construction and combination of parts hereinafter more fully described, having reference to the accompanying'drawings, in which Figure 1 shows my device applied to a window-sash. Fig. 2 is a detail of an individual socket. Fig. 3 is a detail of a' socket-plate. Fig. A is a detail of a rock-shaft. Fig. 5 shows a modification.

A represents a plate adapted to be secured to the upper rail of the lower sash adjacent to one side or the other of the window-frame. An unincased rock-shaft or bolt 2, having a longitudinal sliding movement, is suitably journaled in standards 3 on the plate and is adapted to be moved in and out by means of the arm 4 to engage the gimlet-pointed screwthreaded socket-pieces 5, which are disposed in line in the side rail of the upper sash at suitable intervals.

The arm L carries a projection 6, which is intended to engage in perforations 7 8 in plate A to hold the shaft against longitudinal movement.

Each socket contains a rubber bushing 9," against which the end of the shaft 2 is adapted to abut and prevent the window rattling when the shaft and socket are in engagement and the sashes in locked position. The sockets are adjustable relative to the movement of sashes.

the rock-shaft by means of a screw-driver engaging the notches 10. Consequently whenever the rubber packing 9 becomes compressed and there is any tendency on the part of the sashes to rattle suitable readjustment may be made.

By having a number of socket-pieces in the upper sash either sash may be moved relative to the other and locked at any position, so as to provide ventilation at top or bottom of the window or at both top and bottom. Furthermore, so long as the sashes are thus locked together the Ventilating-space cannot be enlarged by any one from the outside. The lock is secure against being tampered with through the medium of a knife-blade, wire, or other instrument passed up between the Accordingly with windows so safeguarded from marauders lodgers may feel secure in opening their windows for suitable ventilation even where rooms are in a more or less exposed position.

It is to be noted that the ends of the shaft or bolt 2 are symmetrical and that they each have substantially the same amount of movement outside of the standards 3, in which the shaft is journaled. Thisrenders the device interchangeable, so that it may be applied to either right or left of a sash. Hence the reason also for providing the double set of notches 7 8.

By having the bolt somewhat elevated from plate A and unincased it permits the operator when standing on the floor to see a socket above the edge of the top rail of the lower sash and not make it necessary to hunt around blindly with the bolt to find the socket.

In lieu of the individual socket-pieces 5 I may employ a plate, as 11, (shown in Fig. 5,) having the projecting lugs 12 for attachment .to either of the side rails of the upper sash and provided with sockets or pockets 5' at suitable intervals. These sockets would like- Wise contain a resilient packing material 9, as rubber, to prevent rattle when the sashes were locked together. This idea of interchangeableness, whereby the device is indiscriminately applicable to one side or the other of the window, is an important feature of the present invention.

Having thus described my invention, what 2.
