A. E. GERTSFELD LOCK Filed July 7. 1925 dg mzfy ly Patented Dec. 8, 1925.

UNITED STA ES PATENT OFFICE.

ABRAHAM E. GERTSFELD, OF NEW YORK, N. Y.

LOCK.

Application filed July 7, 1925.

Bronx, and State of New York, have in vented a new and useful Improvement in Locks, of which the following is a specification.

This invention relates to an improvement in looks of the character adapted for use upon windows, dumbwaiters, closets, doors of various kinds, and the like, and the object of the invention is to provide such a lock which will be simple in construction although extremely strong and sturdy.

A further object of this invention is to provide a lock of the character mentioned which cannot be readily picked or broken open.

With these objects, and such other objects as may hereinafter appear in view, I have devised the particular arrangement of parts hereinafter set forth and more particularly pointed out in the claims appended hereto.

Reference is to be had to the accompanying drawing, forming a part hereof, in which 1 Iigigure 1 is a plan view of my improved Figure 2 is an end view of the same;

Figure 3 is an end view of the lock keeper; and

Figure 4 is a sectional view on the line 44 of Figure 1, looking in the direction of the arrows, the lock in Figure 4 being shown in its open or retarded position.

Throughout the various views of the drawings, similar reference characters designate similar parts.

In the embodiment of my invention as desclosed in the accompanying drawing, 1 indicates the base plate of the lock and 2 indicates the base plate of the lock keeper. The base plate 1 of the lock is provided with screw holes 3 which may be positioned as desired so that screws may be passed through them to secure the lock to a door or window, a portion of which is indicated at 21 in Fig ure 4.

The keeper 2 is provided with screw holes 4 for a similar purpose and said keeper is also provided with ahead 5 which has a bore 7 for the reception of the bolt 10 of the lock. To add rigidity and strength to the keeper, I provide it with a downwardly Serial No. 41,942.

projecting flange 6 having a screw hole-8 through which a screw may extend to hold the keeper in position. The keeper is thus extremely strong and cannot be very readily pried from the door or window frame 22 to which it is adapted to be secured.

The lock is provided with a tubular boltcasing 9 through which the bolt 10 is mov able. It will be noted that the bolt-casing is open at both of its ends so that when the lock is in its open position, as shown in Figure 4, and the bolt 10 is drawn back or retarded, a part of said bolt is projected out of the back of the casing 9. Toenable the bolt 10' to be manually shifted, it is provided with a pin 11 which passes through it, and said pin moves in a slot 13 provided in the upper part of the bolt-casing 9. The upper end of the pin 11 terminates in a head which lies on the outside of the casing 9 so that it may be readily grasped to draw back the bolt against the tension of the spring 20 which surrounds the bolt within the casing and normally tends to thrust the bolt forward and out of the casing and into the bore 7 of the keeper, retaining the same in its locked position.

At 16 is shown a lock plate or latch member for the lock, said member consisting of a flat curved plate having one of its ends pivoted on a pin 15 which projects from an ear 14 integrally formed on the casing 9. The other end of the latch member is bent laterally as at 17 and said laterally bent portion frictionally engages with a hook-shaped catch 18 on the plate 1, said portion 18 being preferably formed by bending upwardly a portion of the base plate 1.

It will be seen that when the lock is in its closed position, with the bolt 10 projected out of the front of the casing, as disclosed in Figure 1, and the latch member 16 is in its closed position, as indicated clearly in Figure 2, the bolt cannot be forced backward as its rear end bears against the face of the latch member 16, 'which is so shaped that it partly closes the back opening of the boltcasing 9. It will thus be apparent that the lock can only be opened by a person on the inside who can manually raise the pivoted latch-member 16 to the position indicated in dotted lines in Figure 2 to permit the bolt to pass out through the back of the casing when the knob 12 is pressed.

To hold the lock in its open position, as

indicated in Figure 4, wherein the bolt 10 is held in a retarded position within the casing, I provide'the upper face ofthe'bolt 1 with a transverse slot 19 into which the latch member 16 can be moved. The lock can, by the means just described, be indefinitely held in its open position, until the latch member 16 is manually lifted out of the slot 19 to permit the spring 20 to act to force the bolt 10 outwardly and into the bore 7 of the eper- The latch member 1,6 is thereforeutilized to-hold-the boltin its locked or open position by acting as anabutment against the endofthe bolt or by engaging with the slot placed in said bolt.

Having described my invention, what I claim is:

1. An article of the class described comprising a lock casing, a spring pressed bolt therein, said bolt being capable ofhavingvits rear end moved out ofthe back of the casing, a hinged member adapted to act as an'abutment against the rear endof the bolt to prevent such movement, said bolt being provided with a transverse slot into which the hinged member may be positioned when a portion of the bolt has been projected out 'ofthe casing.

2. An articleoi the class described comprising a lock having a fiat baseplate, a tubular bolt-casing thereon, said casing being provided with two open ends, a bolt movable in said casing, a curved latch-plate hinged adjacent to one of the open ends of the easing, said latch-plate being provided with a laterally bent end, a hook member on the through; a spring for normally thrustingthe frontot said bolt outof its casing, .a-fiat plate hinged at the back of said vcasing, means for holding said plate across the back of said casing so thatoneof the faces of said plate partly closes the same anda slot in thetbolt into which the edge of the plate is adaptedto fit whena partofthe bolt is extendedout of the back of the. casing.

Signed atthe city, county and State of New York, this 3rd day of J uly,'1925.
