No. 484,895. Patented Oct. 25, 1892.

UNITED STATES PATENT OFFICE.

EDWARD A. JUDD, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THE CORBIN CABINET LOCK COMPANY, OF SAME PLACE.

PADLOC K.

SPECIFICATION forming part of Letters Patent No. 484,895, dated October 25, 1892.

Application filed July 16, 1392.

To all whom it may concern.-

Be it known that I, EDWARD A. JUDD, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented a certain new Improvement in Padlocks, of which the following is a specification.

My invention relates to improvements in padlocks for bicycles, carpet-bags, and other uses; and the chief objects of my improvements are simplicity and economy of construction and general efficiency of the article.

In the accompanying drawings,Figure 1 is k a front elevation of my padlock with the free end of the chain disconnected therefrom. Fig. 2 is an enlarged front elevation of my padlock with the front half of the case, the front tumbler, and holding-dog removed. Fig. 3 is a like view of the same with the holding-dogin place and the swinging lock-bolt held back thereby, and Fig. 4 is a like view with both the tumblers and dog removed.

I construct the case of two parts A and B, the general form of said parts being the same. In the confronting edges of these parts I form notches or recesses in which to secure a T- head 5 for the attachment of the chain 6. The opposite end of this chain is provided with a shouldered head 7 for being engaged by the swinging lock-bolt 8. The padlock-case is provided with a circular recess or opening 9 at a point diametrically opposite that in which the T-head is received. The swinging lockbolt 8 is of ordinary construction and is provided with a spring 10 for forcing it into engagement with the shouldered head 7. It is also provided with the usual fence 11 for being engaged by the ordinary tumblers 12 and the holding-dog 13. The tumblers are acted upon by a spring 14 to force them into ongagement With the fence when not lifted by other means. I prefer to employ two of these tumblers 12, one upon each side of the holding-dog 13. This dog 13 is provided with a Serial No. 440,205. (No model.)

spring 15 for forcing it in the reverse direction from that of the tumbler-spring and said holding-dog is also provided with an upwardly-projecting portion 16.

By inserting the key and lifting the tumblers the swinging bolt may be swungoutwardly into the position illustrated in Fig. 3, and as soon as it reaches this position the holding-dog 13 under the influence of its spring will be forced upwardly to hold said swinging bolt in its retracted position, as shown in said Fig. 3. The holding-dog in snapping up to this position will bring its projection 16 against the inner end of the shouldered head 7 and force the same out of the padlock.

In order to lock the padlock, the chain is passed through the parts to be fastened and the end forming the shouldered head 7 pushed into the padlock, and in so doing its end will strike the projection 16 and push the holdingdog downwardly far enough to release the swinging bolt, so that it will snap into the position shown in Fig. 2, where it will engage the shoulder of the shouldered head for locking the chain Within the padlock; but at the same time the tumblers will engage the fence 11, as shown in Fig. 2, so as to positively hold the swinging lock-bolt in engagement until it is again released by lifting the tumblers with the proper key.

I claim as my invention The combination of the shouldered head 7, the swinging lock-bolt 8, its tumbler 12 for holding said lock-bolt in engagement with said head, and the holding-dog 13 for holding said bolt out of engagement from said head, substantially as described, and for the purpose specified.

EDWVARD A. JUDD.
