PATENT OFFICE.

'ISAAC W. WEPPI O, OF CHICAGO, ILLINOIS.

LOCKING- JAWS.

Specification ofLetters Patent.

Patented Apr. 4:, 1922.

Application filed. November 15, 1920. Serial No. 424,255.

To all whom it may concern:

Be it known that I, ISAAC W. Wnrrro, a citizen of the United States, and resident of Chicago, in the county ofCook and State of Illinois, have invented new and useful Improvements in Locking Jaws, of which the following is a specification.

This invention. relates to a device attach able to relatively movable objects for the purpose of locking such objects against relative displacement.

The object of my invention is to provide a simple and inexpensive device of the character referred to, which may be attached to sliding doors or other similar mechanisms, without making special preparations for such attachment. To this end my invention consists in the combinations hereinafter described, and a drawing is hereto annexed, in which a structure embodying the invention is illustrated as applied in practice.

In the drawing:

Fig. 1 shows my invention locked in place on a sliding elevator door,

Fig. 2 illustrates the device as it appears when opened and removable, and

Fig. 3 shows a slightly modified torm of my invention.

The elevator door comprises an upwardly slidable portion 1, and a downwardly movable member 2. Such doors are usually made of corrugated. sheet metal, as indicated in the drawing by the reference numerals 3 and 4t, and the abutting edges are reinforced by securing an angle bar 5 to the bottom edge of slide 1, and a corresponding bar 6 to the top edge of the member 2. In the folds of the corrugations of said slides and within the flanges of the angle bars are thus provided pockets into which the structure of my invention may be inserted, as clearly illustrated.

This structure of my invention takes the shape of a pair of jaws 7 and 8, and these jaws may be identically shaped as indicated, in order to reduce the manufacturing cost of same. The jaws are pivotally combined by means of a rivet 9, and they are locked together in closed position by means of a suit able padlock 10. The shape of each jaw is important, as will be observed upon exami nation of the drawing, partly on account of its compactness and strength and also because the structure presents no projecting corners capable of causing injury to a person passing or stationed nearthe door to which the structure is attached.

Each jaw is substantially shaped like a capital L, and it is provided with a perforation 7 at the top and one 7" atthe apex, (it being noted that the L 7 in the drawing is shown inverted). The hooks 7, 8 are shaped to project over the edges of the angle bars, and the only requirement is that they must be at least as strong as the door structure, in order that the latter may break first, in case an intruder attempts to break the jaws away from the door. And the jaws may be made from hardened steel, such strength may easily be attained.

Now it may be said that not all doors, or similar sliding structures, are made from corrugated sheet metal. For the purpose of tire protection and in order not to make them unduly heavy they are mostly so constructed. But even wooden doors, as indicated in Fig. 3, may be locked by means of my invention. For this purpose I provide jaws 12, 13, with sharpened hooks 12 13. A few taps with a hammer causes said hook to penetrate into the wood, and to lodge behind the reinfor ing. bars lat, 15, with which such wooden doors always are provided. And once the jaws have been driven into place, they may thereafter be inserted in the pockets thus created.

I claim:

1. The combination with the abutting edges of a sliding door, of a pair of pivotally combined. jaws capable of engaging said edges, and means for locking said jaws against disengagement.

2. The combination with the abutting edges of a sliding door having reinforcing bars along said edges, of a pair of pivotally combined hooks insertable behind said bars, and means for locking said hooks together.

3. The combination with the abutting edges, of a sliding door having reinforcing bars along said edges, of a pair of pivotally combined jaws having hooks capable of insertion behind said bars when the jaws are closed,- and provided with perforations brought into registration when the aws are thus closed. and means engaging said aligned perforations for locking the jaws in closed position.

4. A. locking structure comprising two when the levers are swung into closed position 'for the accommodation. of locking means.

6. The combination With the abutting edges of a wooden sliding door having reinforcing bars along said edges, of a pair of pivotally combined jaws insertable behind said bars for the purpose of maintaining the door closed, said jaws provided with sharpened points capable of penetrating into the WOOCl behind said bars, and means for to ether.

I AAC \V. \VEPPLO.
