WINDOW-LOCKING DEVICE.

Specification of Letters Patent. Patented Aug. 30, 1921.

Application filed June 24, 1920. Serial No. 391,267.

To all whom it may concern Be it known that I, EPHEEM A. RosEN- BERG, a citizen of Russia, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Window-Locking Devices, of which the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to a window looking device, and has special reference to that class of devices carried by window sashes for connecting the sashes together so that the sashes may be adjusted in synchronism.

My invention aims to provide simple and durable pieces of hardware that may be easily and quickly attached to window sashes to permit of a lower sash being automatically connected to an upper sash, when the lower sash is raised or opened, thus preventing excessive adjustment of the lower sash and any adjustment without moving the upper sash. The advantage gained by such a constructive arrangement of parts is that of limiting the opening movement ofthe lower sash relative to an upper sash and permitting of the operator of the lower sash adjusting the upper sash without using a sash stick or similar tool. Then again, proper ventilation of an apartment is had when a lower sash is closed, by reason of the upper sash being opened due to its connection with the lower sash. This connection, however, is optional and provision is also made to compensate for sashes of different thicknesses, thus permitting of the locking device being applied to any window sashes to prevent burglarizing.

The mechanical construction entering into my invention will be hereinafter more fully described, and then claimed, and reference will now be had to the drawings, wherein- Figure 1 is a perspective view of a portion of a window frame and sashes, showing the sashes articulated for movement in synchronism;

Fig. 2 is a vertical sectional view of a portion of the sashes in closed positions, showing the device to be automatically actuated by the lower sash, and

Fig. 3 is an enlarged detail sectional view of the locking devices articulating the window sashes.

In the drawing, the reference numeral 1 denotes the meeting rail of a lower window sash 2 and 3 is one of the side rails of an upper sash 4, these window sashes being adustable in a conventional form of window frame 5.

6 denotes a channel ratchet member vertically disposed onthe side rail .3 of the upper sash 4L, and connected thereto by screws 7 or other fastening means, said channel ratchet member being ositioned at a desired height above the meeting rail 8 of the upper sash.

The channel ratchet member 6 has its side walls 9 provided with a series of notches 10 and the lower ends of the side walls 9 terminate in stop members 11, which project outwardly from the member 6 and provide a central guide slot 12. Pivotally mounted in the inner end of the slot 12 is the slotted end of an arm 13, the slotted end of said the latch 17 to the arm 13 serves as a support in the side walls 9 of the member 6 for holding the arm 7 in approximately a vertical position with the lower slotted end of said arm protruding from the lower end of the member 6, as best shown in Fig. 2, and when the arm is in such position the latch 17 hangs from the upper end of the arm and partially within the channel member.

19 denotes a keeper mounted on the meeting rail 1 of the lower sash 2 at the upper end of the side rail of said sash, and this keeper is adapted to be engaged by the latch 17 when the lower sash is employed for lowering the upper sash, also when the sashes are locked together.

The normal condition of the locking device is shown in Fig. 2, and assuming that the lower sash is raised the meeting rail 1 thereof impinges against the inner end of the arm 13 and raises said arm so that the ends of the pin 16 will ride out of the notches 10 of the channel member. On account of the pivotal arrangement of the arm 13, the

sashes being locked together by the arm 13 and the latch 17 the lower sash cannot be lowered without lowering the upper sash nor can the upper sash be lowered without lowering the lower sash. It is therefore obvious that when an operator closes the lower sash 2 that the upper sash 4 is lowered for ventilating purposes, but should the operator desire to close the sash 2 without opening the sash 4 then the latch 17 is elevated and the arm 18 placed within the channel member 6, as shown in Fig. 2.

The pieces of hardware may be finished to harmonize with finish of the sashes 2 and" 4, and while in the drawing there is illustrated the preferred embodiment of my invention, it is to be understood that the structural elements are susceptible to such changes, in size, shape and manner of assemblage as fall within the scope of the appended claims.

\Vhat I claim is:

1. The combination of an upper sash, a lower sash, a keeper on the inner face of said lower sash, and an arm carried by a side rail of said upper sash above the meeting rail thereof and adapted to be shifted 'by the meeting rail of said lower sash engaging the lower end of said arm when said lower sash is raised to cause said arm to engage said keeper and connect said sashes so that the upper sash may be lowered with the lower sash.

2. The combination set forth in claim 1,

wherein a channel member supports said arm and is connected to the upper sash to support said arm in a position to be actuated by the meeting rail of said lower sash.

3. A window lock device comprising a channel member adapted for attachment to the side rail of an upper sash to limit the upward'movement of a lower sash, an arm loosely connected to said member, a latch carried by said arm, a pin connecting said latch to said arm and adapted to support said arm in said member to be engaged, and shifted by the rail of the lower sash and a keeper adapted for attachment to the lower sash to be engaged by said latch to articulate the sashes so that said sashes may 7 be lowered in synchronism.

4. A window locking device as characterized in claim 3, wherein the channel member is notched to receive said pin, and said pin adjustable relative'to said arm to compensate for sashes of different thicknesses.

5. The combination of an upper sash, a lower sash, and means carried by said upper sash normally supported to be actuated by the raising said lower sash to articulate said sashes so that said sashes may be lowered together.

In testimony whereof I afiix my signature in the presence of two witnesses.
