DEVICE FOR LOOKING SCREEN DOORS AND THELIKE Filed Oct. 22, 1928 Patented Dec. 23, 1930 UNITED STATES O FIC JAMES E. TAYLOR, or oLEvELAnD, oHro DEVICE non LOCKING soannnnoons AND THE LIKE Application filed October 22, 1928. Serial 1T0: 314,016.

.This invention relates to locking devices, particularly those which are commonly used for locking screendoors, window screens and the like. One form of device heretofore used for this purpose has embodied a single hook member, which is usually fastened upon the screen or door and is adapted to engage an ye member upon the door or window jamb.

It is an easy matter for locks of this nature to be opened by unauthorized persons merely by the insertion of a tool through the screen and by raising the hook member out of conhook out of engagement with the cooperating 3 A further object of my invention is to make a locking device which is simple in construction and which may be readily made and easily operated when in use.

Referring to the drawings, Fig. 1 is a perspective view of a screen or door which is locked by the device embodying invention; Fig. 2 is a perspective View of the looking device removed from the screen, and showing the locked position thereof; Fig. 3 is a side elevation of the lock showing the keeper in two different positions; Fig. 4 is a side elevation of the lock in closed position; and Fig. 5 is a top'plan view of the lock.

The preferred form of my invention comprises a hook member 10 and a keeper-11., which is slidable along the hook and which cooperates with an arm 12 to lock the hook in lace. The hook and arm as shown are made of a single piece of wire, which is bent to form a loop 13 through which a fastening member 1.4 may extend forsecuring the hook to a 50 screen or door 15. The elasticity of the wire permits thearm to be moved slightly withreferenceto the hook whenever desired. Such movement :is sufficient for-enabling the hook to be passed through aneye 16 in thedoor or windowjamb as is "shown in Fig. 1. 8 I The open position -of the keeper is illustrated by the full lines ofFig. 3 wherethe hook and arm are illustrated as being moved apart a suflicient distance to clear the locking eye. After the hook is placed over the eye, the

.keeper is moved forwardly to a position shown at 11c bythe broken lines-in Fig. 3.

The keeper, as illustrated, is made from a single piece of :wire bent to the shape of a figure -8. The hookmember has a notch 20 into which the top loop 'of the-keeper may'extend. andthe arm 12 is also shown as having a notch 21011 the underside thereof intowhich the bottom loopof the keeper may extend. The notch 21 is {in a re-entrant portion 22, which is formed'bybendingthe arm first outwardly, as at23, theninwardly'as at 24, and

then outwardly again as at 19. Thearm thus has a substantial hump or shoulder over which it must pass before it can be withdrawn to theopen position. Moreover such hump prevents the look from being opened merely by forcingthe keeper backwardly along the hook. Notches 30 and31 also function to assist in holding the keeper in position. To openthe lock, it is'necessary to press the arm andkeeper slightlyitogether, until the bottom part of the keeper falls out of the re entrant portion22. .By making the notch21 nearer to the end-of the hook than the notch 20, the keeper occupies a position, when locked, extending obliquely to the direction of the hook. Thus, the action of gravity assists in making the'keeper clear thehump, whenever the arm is pressed toward the hook while the door is locked. In locked position, the looped portion 25 at'the end of the arm is sufiiciently close to the end 26 of the hook, that the lock cannot be opened when shifting the keeper to the open position.

I claim:

1. A locking device comprising a strip of wire bent to provide two arms, a keeper slidable along the arms, each of said arms having a notch therein adapted to be engaged by the keeper when the keeper is in locking position, said notches being oifset with relation to each other, whereby the keeper extends diagonally to the arms when in locked position.

2. In a device of the character described, the combination with a single strip of wire bent intermediately to form a loop, and having two arms extending from the loop in the m same general direction, the end of one of the arms being shaped to form a hook, and the end of the other of said arms being shaped to form an eye, into which the end of the hook extends, a member movable along said arms and being adapted to occupy one position when said arms are closed, and to occupy another position when said arms are opened, and means associated with said arms and acting upon the member for holding the arms in closed position, said means permitting movement of the keeper to open position when the arms are pressed together a predetermined distance.

3. A device of the character described, comprising in combination, a strip of wire bent intermediately to form a loop with two arms. extending from the loop and in the same general direction, one of the arms having the end thereof shaped to form a hook and the other of said arms having the end thereof shaped to form an eye to receive said hook portion when the arms are moved toward each other, said last mentioned arm having that portion thereof near the eye curved in two directions 5 to make a re-entrant portion, a keeper slidable along the arms and being formed of a single strip of wire looped to en age each arm, one of the loops of the keeper being adapted to engage one arm behind the hook and to engage the other arm within the re-entrant porion for holding the arms in locked position.

4. A device of the character described, comprising a strip of wire bent to provide a pair of arms movable with relation to each other, one arm having a recess facing outwardly, the other arm having an outward bend providing a pair of shoulders spaced apart, and a keeper slidable along the arms and adapted to occupy said recess and swing about it as a center into engagement with either of the shoulders of the other arm.

In testimony whereof, I hereunto aflix my signature.

JAMES E. TAYLOR.
