LOCK..

SPECIFICATION forming part of Letters Patent No. 759,432, dated May 10, 1904. Application filed May 9, 1903. semi No. 156,487. (No model.)

To all whom, it may concern:

Be it known that I, FRANK M. GALE TIN, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Locks, of which the following is a specification.

This invention relates to looks, and is designed to provide an improved seal-lock which is particularly adapted for application to sliding doors-as, for instance, the doors of freight-cars.

It is furthermore designed to have the invention embodied in a very simple and inexpensive form, with the parts thereof arranged for convenience in locking and unlocking and for the application of a frangible seal.

Another important object of the invention is to obviate damage and accidental breakage of the frangible seal by jolting movements of the hasp or locking member incident to the use of the look upon a car-door.

With these and other objects in View the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, porportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is an elevation of portions of a freight-car and the slidable door thereof with the lock of the present invention applied thereto. Fig. 2 is'adetail perspective view of a lock constructed and arranged in accordance with the present invention. Fig. 3 is a top plan view thereof, and Fig. 4 is a detail sectional view taken through the locking tumbler or detent.

Like characters of reference designate corresponding parts in each and every figure of the drawings.

Thepresent embodiment of my invention includes an attaching member 1, preferably in the form of an oblong plate having terminal perforations 2 for the reception of suitable fastenings 3 (indicated in Fig. l of the drawings) for rigidly securing the plate to the side of a building or to the side of a car 4. At about the middle and upon the front of the attaching member is a keeper 5 in the form of an integral boss or projection of substantially elliptical shape, said keeper being projected beyond one edge of the plate. Associated with this keeper is a rotatable tumbler or detent 6, corresponding substantially in shape and size to the keeper, with one end pivoted upon a fixed pivot-pin 7, projected from the front face of the keeper. Corresponding openings 8and9 are formed through the tumbler and the pivot-pin for a purpose as will be hereinafter more fully described. Near what'is normally the lower end of the tumbler a transverse opening or passage 10 isformed therethrough, and opposite edge grooves '11 lead downwardly from the ends of this opening;

The'locking member 12 is in the form of a hasp one end of which is provided with perforation 13 for the reception ofa pivot-fastening 14 (shown in Fig. 1 of the drawings) for pivotally mounting the hasp upon the door 15. The opposite free end of the hasp is enlarged and provided with an eye 16, corresponding in shape and adapted to receive or embrace the keeper 5, and thereby prevent accidental endwise movement of the door.

It will of course be understood that the hasp or looking member 12 has a loose pivotal connection with the door to permit of a suificient lateral or outward movement of the hasp in engaging the latter sidewise with the keeper. Prior to engaging the hasp with the keeper it is of course necessary to turn the tumbler 6 upon its pivot 7 until it has been alined with the keeper, and after the eye of the hasp has been engaged with the keeper the tumbler is permitted to drop by gravity, and thereby overlap and lie across the hasp to prevent lateral displacement thereof from the keeper; To disengage the hasp from the keeper, the tumbler is turned into alinement with said keeper and the hasp is then removed laterally from said members, whereby the door is free to be opened.

To indicate unauthorized unlocking of the lock, it is designed to equip the same with a seal, and this feature is carried out by inserting a Wire 17 through the alined openings 8 and 9 of the tumbler and the pivot-pins therefor, the opposite ends of the Wire being brought together across the top of the detent and thrust into or otherwise connected by means of the common or ordinary lead diskshaped seal 18. When the seal has thus been applied, any attempt to bring the detent into alinement With the keeper 5 Will result in a cutting or severing of the wire 17 by the shear-like action of the Walls of the openings 8and 9 in the detent and its pivot-pin. In addition to and also in lieu of the seal the shackle of an ordinary padlock may be passed through the opening 10 of the detent for the purpose of effectually locking the hasp against accidental or unauthorized removal from the keeper.

Having thus described the invention, What is claimed, and desired to be secured by Letters Patent, is

A look embodying a keeper, a hasp having an eye to embrace the keeper, a pivot-pin carried by and projected in front of that portion of the keeper to be embraced by the hasp and rigid with respect thereto, and a lockingtumbler pivoted to swing upon the pin as a center and capable of a'linement with the keeper and also of being turned across the hasp to lock the same upon the keeper, the movable tumbler and the fixed pivot-pin having corresponding seal-receiving perforations disposed in a plane at one side of the hasp.
