SASH LOCK.

Application filed March 9, 1922. Serial No. 542,237.-

To all whom it may concern:

Be it known that I, CLYDE S. MORSE, a citizen of the United States, residing at De Kalb, in the county of De Kalb-and State of Illinois, have invented certain new and useful Improvements in a Sash Look, of which the following is a specification.

This invention relates to improvements in locks for sliding or slidable windowsashes, and has for its principal object, to furnish a highly efiicient, reliable, strong and durable lock, of an extremely inexpensive construction, with its parts so made, arranged and co-operating with one another, as well as with the window-sashes, as to enable it to be readily mounted in position for use, by an unskilled person, and when so mounted will be ever ready to hold or lock the sashes against sliding movement of eithen, no matter what positions they may occupy, and besides, will so hold the sashes with respect to one another and the sash frame, as tol prevent rattling.

Another object is to so construct the device that it will beautomatic in its locking action, yetmay be held in its released postion in order that the sashes may be freely moved when desired.

- A further object is to provide means whereby the face of the side rail of the sash With-which the locking member of the device engages, will not ordinarily be marred thereby.

Other objects and advantages of the invention will become apparent from the fol? lowing description and explanation.

The invention consists in certain peculiarities of the construction. novel arrangement and combination of the various parts thereof, as will be hereinafter more fully set'forth and specifically claimed.

In the accompanying drawing, which serves to illustrate an embodiment of the 'Figf 1 is an inner perspective view partly in section and partly in elevation showing a partof the jamb or side wall of a Window frame with portions of the upper and lower sashes mounted in a guide-way thereon and illustrating my improved sash lock supported on the side rail-of the lower sash in looking engagement with the side rail of the upper sash. Y

Fig. 2' is an inner viewpartly in section and partly in elevation of portions of the sashes and frame therefor showing the look by continuous lines in the position its parts will occupy when the sashes are looked thereby.

Fig. 3 is a, vertical sectional view taken on line 33 of Fig. 2 looking in the direction indicated by the arrows, and

Fig. 4 is a detached perspective view of the base plate of the device.

Like numerals of reference refer to'cor-- responding parts throughout the different views of the drawing.

Thereference numeral 5 designates a ortion of one side of a window frame w ich is provided with a vertically disposedguideway 6 for the upper and lower sashes one of the side rails of each of which is designated by thenumerals 7 and 8 respectively. Mounted on the upper end of theside rail 8 of the lower sash is the base plate of the device, which plate is designated as a whole by thenumeral 9 and by preference consists of a rectangular piece of metal provided near its corners withopenings 10 for the insertion of screws or similar fastening devices used for securing it to the top of one of the side rails. of the lower sash. The

plate 9 is provided with a pair of spaced by preference 1uprights 11. which are punched out of theplate 9 as shown in Fig. 4 and each of said uprights is provided with a transverse. opening 12 for the reor pivotally mounting thelocking member 14 of the device on said base plate.

As is clearly shown in Figs. 1 to 3 inclusive of the drawing, thelocking member 14 is provided at its front or'outer end with asocket 15 which is substantially rectangular in cross-section and is formed by bending downwardly the sides of the front portion of themember 14 and then bending said portions towards each other so as to form afloor 16 at a distance below the upper wall of the socket. Themember 14 also has extended downwardly from each of the side edges of its elongated part 17 aflange orextension 18 which are located in parallelism with one another and spaced at a suliicient distance apart to stride theuprights 11 as is clearly shown in Fig. 2 of the drawing. Each of these flanges or downwardextensions 18 is provided with an opening which register with theopenings 12 in theuprights 11 and are for the reception of thepivot 13 ception of apivot pin 13 used for tiltably' which serves to hold thelocking member 14 in position on theuprights 11 yet so that it can be rocked thereon.

Coiled around thepivot pin 13 is a spring 19 one end of which rests against the lower surface of an up-turnedportion 20 of thelocking member 14 while the other end of said spring rests a ainst theplate 9 below said up-turned portlon. This up-turned portion provides a thumb or finger rest by means of which thelocking member 14 may be tilted to about the position shown by dotted lines in Fig. 3 when ,it is desired to release the locking member from theside rail 7 of the upper sash. Located in thesocket 15 of the locking member is aplug 21 of rubber or other suitable resilient material, the free or outer end of which is adapted to impinge against the face of therail 7 of the upper sash. Mounted on theplate 9 near one side of the thumb rest or upwardextension 20 of the locking member for rotary movement, is acatch member 22 which is provided with a laterally extendedportion 23 so that when thelocking member 14 is positioned about as shown by dotted lines'in Fig. 3, thecatch member 22 can be turned on its pivot so that itslateral extension 23 will engage the upper surface of thethumb rest 20 and thus hold the locking member in its released position, when it is manifest that the sashes can be freely moved. i

From the foregoing and by reference to the drawing it will be readily understood and clearly seen that by means of my improved sash lock, when thelocking member 14 thereof is held in its released position as shown by dotted lines in Fig. 3, either by a eeaew E means of the hand of the o erator or by sponding portions of the window frame for I ventilating purposes, and that by releasing the lOCkiIlg member, its front end will en-.

gage the adjacent surface of theside rail 7 of the upper sash in such a way as to prevent the movement of either sash.- When thus positioned the lock will hold the sashes against the side walls of the guide-way in such a way as to prevent rattling.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is: I

In a sash lock, the combination with a base-plate having means to secure it to a sash and provided with a pair of spaced and apertured uprights, of a locking member having a socket at one of its ends and an up-turned portion at its other end, said member being provided with depending and apertured side flanges co-acting with said uprights to sup ort said member, a pivot pin located in t e openings of said flanges and uprights, a resilient plug located in said socket and extended outwardly therefrom, a catch member rotatably mounted on the baseplate near the up-turned portion of the look ing member, and a spring surrounding said pivot pin and, resting at one end against the base-plate and at its other end against the lower surface of the locking member near its end opposite its socket.
