BY ATTORNEYS.

Patented Dec. 29, 1931 JOSEPH B. SOLOMON, F OAKLAND, CALIFORNIA wmmw SAFETY Lock AppIication filed January 25,1930, Serial No. 423,372;

My invention relates to improvements'in 7 window safety locks, and'it consists in the combinations, constructions and arrangements herein after described and claimed. In ofiicebuildings and inother types of buildings such as homes for the aged and insane asylums, someaneans should be provided for permitting the window sashes to be opened a slight distance for allowing air to enter and leave the room, but this means should limit the opening of the window sashes so as to prevent a person from accidentally stepping out through a window fully opened or from intentionally stepping out man attempt to commit suicide.

With the above objects in View, I have designed a window safety lock that will permit' the upper and lower sashes to be moved a predetermined distance and then be'prevented from further movement unless an authorized person temporarily releases the locking me chanism to permit the full opening of the win dow sashes; to permit the Window sashes to be opened a L slight distance or a greater distance.

It should further be noted'thatfthe device is especially adapted for use in homes to prevent burglars from moving the sashes into knows the secret combination.

Other objects and advantages will appear i as the specification proceeds, and the novel features of the device will be particularly pointed out in the claimshereto annexed.

My invention is illustrated in the accompanying drawing, in which:

Figure 1 is a front elevation of a window showing my device operatively applied thereto,

Figure 2 is a Vertical section througha portion of the device, and

The device is adjustable so as Figure 3 is an enlarged view of a portion To this window I securearod 4. that hasa number of recesses 5 therein equally-spaced from each other. These recesses may be arranged close together if desired, or they may be separated from each other a considerable distance. i The rod .L'is received in a socket 6 that 111 turn is secured to the window frame 1 and'in a second socket 7 that is also secured to the window frame. The rod 4 is preferably disposed adjacent to one side-of the frame so as'n'ot to obstruct the view, but it is obvious that it may be placed indifferent positions other than that shownin Figure 1. Each window sashcarries an arm, and I have numbered these-arms 8 and'9 respec tively. The arms have bores for slidably receiving the rod 4:, and carry rubber bumpers-10 and 11' for a purpose hereinafter-dc scribed. 1 I V fThe particular construction of the lock is shown in Figure 2. I provided two locks '12, one for each arm 8 and 9, and these locks are adjustable on the rod 4: soas to-determine the amount of opening of the

sashes

2 and 3. Referring to Figure 2, it will be noted l that the lock 12has a bore 13 therein for receiving the rod 4. A spring-pressed locking pinl l is carriedby the lock '12 andis full open position after the sashes have been partly opened. The device is extremelysimple in construction, and may be key-actu-. ated or actuated by an authorized person who" designed to enter any, one ofthe. recesses 5.

Pins 15 guide the locking pin 14:, and a spring 16 urges the locking pin into the 'recess 5.

When the pin is received in the recess,'the lock 12 cannot be moved on the rod 5.

I provide two means for releasing the looking pinl. I will first describe the keycont-rolled means. -A gear 17 is mounted within the lock 12 and meshes with a rack 18' formed onlthe locking pin 14. The gear andfreethe locking pin" 14 from the recess,

5. "The lock 12 maynow be moved into'any position desired, "and the freeing of the key (not shown). will cause the spring 16 to again :t seat' thelocking pin. 14. in the recess 5. for

any desired place on the rod a.

r the arms abut the locks.

preventing further movement of the lock 12.

A manually controlled means is also provided for releasing the pin 14.. At the bottom of the lock 12 I mount a collar 21 that is threaded upon the lock 12. When this collar is released from the lock 12, an arm 22 is exposed. This arm is rigidly connected to the lockng pin 14 so that a manual movement of the arm to the left in Figure 2 will free the locking pin from the recess. A spring clip 23 receives the arm 22 and yieldingly holds it in place with the bolt 14 retracted so that the lock 1 may be freely moved along the rod. hen the lock is disposed in the desired position, the arm 22 is moved to the ight and is freed from the spring clip 23. The collar 21 may now be screwed upon the lock 12 so as to hide the arm 22.

The collar 21 carries a resilient bumper 24 that abuts the

bumpers

10 or 11 when the arms 8 or 9 are moved into engagement with the locks 12. The bumpers prevent the shattering of the glass should too much force be used in raising the window sash.

Vhen the locking pin 14 is key-actuated, it also moves the arm 22, and'the arm is received in the spring clip 23 in the same man ner as already described. This holds the locking pin 14: out of engagement with the rod 4 until the key is again turned for freeing the arm 22 from the spring clip 23.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

The device may-be applied to any standard window, and the locks 12 positioned in The locks permit the window sashes to be opened until Further movement is. prevented unless the lock is released from the arm 4; by an authorized person who has a key or who has the knowledge of how to\ gain access to the arm 22.

Although I have shown and described one embodiment of my invention, it IS to be understood that the same is susceptible of various changes, and I reserve the right to employ such changes as may come within the scope of the invention as claimed.

The lock can be replaced with a new one without inconvenience to anyone.

I claim:

1. A window safety lock comprising a rod having recesses therein, locks adjustable on said rod and having plungers removably receivable in the recesses, arms slidable on said rod and being secured to the window sashes, said locks limiting the movement of the arms.

.2. A -window safety lock comprising a rod having recesses therein, locks adjustable on said rod and having plungers removably receivable in the recesses, arms slidable on saidrod and being secured to the window sashes, said locks limiting the movement of the arms, and resilient bumpers carried by said locks and arms for abutting each other when the arms are moved into contact with the locks.

3. A window safety lock comprising a casing having a bore for slidably receiving a rod having recesses therein, a spring pressed pin carried by said casing for entering the recesses, an arm carried by said pin for moving it, a collar normally covering the end of the arm and being removable from the casing for permitting the arm to be moved.

a. A- window safety lock comprising a casing having a bore for slidably receiving a rod having recesses therein, a spring pressed pin carried by said casing for entering the recesses, an arm carried by said pin for n1oving it, a collar normally coveringthe end of the arm and being removable from the casing for permitting the arm to be moved, and a spring clip for holding the arm and pin in retracted position.
