ST TES CHARLES PRESSLER, OF IDANNEMORA, NEW YORK, ASSIGNOR OF ONE-HALF TO JOHN VIVIANO.

SASH LOCK.

Application filed January 2, 1925. Serial No. 192.

T 0 all whom it may concern:

Be it known that 1, CHARLES Pnnssnnn, a citizen of the United States, residing at Dannemora, in the county of Clinton and State of New York have invented new and useful Improvements in Sash Locks, of which the following is a specification.

This invention relates to a lock for sashes, closets, cabinets and the like, the general object of the invention being to provide a lock member with manually operated means for holding the member in the keeper part so that the lock member cannot be withdrawn without first moving the manually operated means to inoperative position.

Another object of the invention is to pro vide spring means for moving the locking member to inoperative position as soon as the manually operated means is released therefrom.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a plan view showing the invention used as a sash lock.

Figure 2 is a section on line 2-2 of Figure 1.

1 ln these views, 1 indicates a part of the lower sash and 2 indicates a part of the upper sash. A bolt 3 is carried by the part 1 and a sleeve 4 is placed on the exposed part of this bolt to form a rest for the hook shaped locking member 5. A washer 6 and nut 7 hold the parts in position. A finger engaging member 8 is placed on the outer end of the locking member 5 and a spring 9 is placed on the sleeve and engages a part of the member 1 and the locking bolt 5 and tends to hold the member in inoperative position, as shown in dotted lines in Figure 1. A. base 10 is carried by the part 2 and this base has a tubular keeper part 11 having transverse holes 12 therein for receiving the hooked part of the member 5. The upper part of the keeper 11 is threaded to receive the threaded shank 13 of a turn screw 14, the shank having a reduced part 15 for engaging a hole 16 in the hooked part of the locking member.

From the foregoing it will be seen that when the locking member has been swung to a position where its hooked part will pass through the holes 12 in the keeper 11 and the turn screw ll turned to place its reduced part 15 in engagement with the hole 16 in the locking member, said member will be held in the keeper and it will be impossible to release it from the keeper until the turn screw is given a reverse rotation to with draw the part 15 from the hole 16. "When this is done the spring 9 will move the locking member to inoperative position as shown in dotted lines in Figure 1. A stop pin 1? may be provided for limiting the outward movement of the locking member. ll ith this device it will be impossible for a burglar to pry the two sashes apart and more the locking member with an object as is frequently done with the sash locks now in the market. The screw 14.- will positively hold the locking member in the keeper 11 until it is moved upwardly to release the locking member from the part 15. The finger part 8 facilitates movement of the locking member by the fingers of one hand.

it is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is z- A look of the class described comprising a support, a locking member having a hookshaped end rotatably mounted on the support, a spring for holding the locking memher in inoperative position, a keeper member for receiving the hookshaped part of the locking member and a turn screw in the keeper member for fastening the locking member therein.

In testimony whereof I aflix my signature.

' CHARLES PRESSLER.
