MAX L. GORDON, OF LOS ANGELES, "CALIFORNIA, ASSIGNOR OF ONE- HALF TO CHAS. E. PACKMAN, OF LOS ANGELES, CALIFORNIA* SPECIFICATION forming part of Letters Patent No. 763,879', dated June 28, 1904.

Application filed July 1, 1908, Serial N0. 163,962. (No model.)

To (LM whom, t may concern:

Be it known that I, MAX L. GORDON, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Sash-Fasteners, of which the following' is a specification.

My invention relates to new and useful improvements in sash-fasteners; and its object is to provide a simple and inexpensive device which may be readily attached to a windowframe and which will securely lock a sash in any position to which it may be moved, thereby permitting sash balances and cords to be dispensed with. y

Vith the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the drawings, Figure 1 is an elevation of a portion of a window sash and frame, the same being broken away to show the sash-lock in elevation and to show the means for fastening the rack to the window-sash. Fig. 2 is an enlarged horizontal section through the sash-lock. Fig. 8 is an elevation of a portion of a window-frame having myimproved sashlock therein, and Fig. 4 is a vertical section through the lock.

Referring to the figures by numerals of reference, 1 is a bar having V-shaped teeth 2 on the outer face thereof, and the ends of this bar are provided with arms 8, arranged at right angles thereto. rIhe bar 1 is adapted to be placed upon one side edge of a windowsash 4, and the arms of this bar overlap the ends of the sash and are secured thereto by means of screws 5 or other suitable fastening devices. The inner surface of the windowframe 6 is slotted in alinement with the bar l, as shown at 7, and secured within the frame adjacent this slot is a slotted plate 8, having horizontally-extending arms 9, connected by a cross-strip 10. One of the arms 9 has a longitudinally extending slot 11, through which extends a revoluble rod 12v, which also projects through a slot 18, formed in the inner face of the window-frame 6. At the inner end of rod 12 is arranged an arm 14, which extends at right angles to said rod and projects through the slotted plate 8 and the slot 9, the inner end of this arm being tapered and normally engaging two of the teeth 2 on bar 1. A bow-springl is riveted or otherwise secured to the Vcross-strip 10, and the other end thereof is fastened in any suitable manner to a block 16, secured to the rod 12 in a plane at right angles to the arm 14. vThis spring serves to hold the rod 12 normally in position in the front end of the slot 11, and

`the arm 14 is therefore normally in engagement with the teeth on the rod 1. A suitable cap 17 is secured to the inner face of the window-frame 6 and forms a bearing for rod 12. A lever 18 is arranged at the outer end of rod 12, as shown.

When it is desired to lower the windowsash 4, the lever 18 is moved in the direction of the arrow shown in Fig. 3, and the arm 14 is thus swung downward out of the path of the teeth 2. The sash can then be lowered, and when it is desired to lock the same the lever 18 is released and is promptly thrown backward into horizontal or normal position by spring 15, and thereby rengages the teeth 2 and holds the sash. When it is desired to raise the sash, lever 18 is turned in the opposite direction, and the operation above described is then repeated. By slotting one of the arms 9 the rod 12 and its arm 14 can be moved within the frame 6, so as to permit said arm to engage the teeth 2, even though the sash does not fit snugly within the frame 6.

The device is very simple and inexpensive in construction and can be readily placed in position. The plate 8 can be fastened in the frame-by means of screws 19 or in any other suitable manner.

In the foregoing description I have shown the preferred form Yof my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes and alterations as may fairly fall within the scope of my invention.

the arm, a block secured to the rod adjacent the arm, and a bow-spring permanently secured at opposite ends to the block and crossstrip, respectively, said spring serving to hold the arm normally in engagement with the toothed rod, and a lever secured to the revoluble rod.

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