HENRY G. VOIGHT, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THE RUSSELL & ERVVIN MANUFACTURING COMPANY, OF SAME PLACE.

PAD LOCK.

SPECIFICATION forming part of Letters Patent No. 600,627, dated March 15, 1898.

Application filed December 1S, 189 7. Serial No. 662,373. (No model.)

To all whom t may concern:

Be it known that l, HENRY G. VOIGHT, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Padlocks, of which the following is a specification.

My invention relates to improvements in padlocks; and the objects of myimprovements are simplicity and efficiency of the article.

In the accompanying` drawings, Figure 1 is a front elevation of my padlock with one-half of the case and one lockplate removed and the key in transverse section. Fig. 2 is a like View of the same with the parts in a different position. Fig. 3 is an enlarged sectional view of my padlock on the line c m of Fig. 1, and Fig. 4 is a detached view of the combined dog and tumbler-carrier on the same scale as Fig. 1.

A A designate the two parts ofthe case, within which the lock-plates 5 6 and connected parts are held. The shackle B is mounted to swing 0n the pin or post 7 At its heel is a wing or extension 8, the rounded end of which acts in connection with the curved face 9 of the swinging bolt 10 to prevent said bolt from being prematurely forced into its position for locking, while the side face of said wing serves as a bearing for the spring 11, that forces the shackle to its open position. The shackle B is also provided with a nose 12 and locking-shoulder 13. The swinging bolt 10 is pivoted on the pin or post 14, and is provided with a locking end 15 for engaging the locking-shoulder 13 of the shackle and with a wing or lever 16 for being engaged by the nose l2 of the shackle. The other end of the bolt 10, in addition to the curved face 9 before specified, has an angular heel 17, the under face of which (in the position illustrated) is for engagement with the top of the wing 18 of the locking-dog and tumbler-carrier 19, as shown in Fig. 1, while its righthand face is for engagement with the lefthand face of said wing to hold the tumblercarrier 19 back, as shown in Fig. 2. The form of the tumbler-carrier and dog 19 is shown in Fig. 4. The talon 25 for the key 26 is fully shown only in this view. Said carrier is mounted on the pin or post 20, provided with a stud or lug 21 for the spring or springs 22 of the tumbler or tumblers 23 'and with the pin or post 28, upon which said tumbler or tumblers are mounted eccentrically to said carrier, whose aXis is the post 20. These tumblers are shouldered and slotted at their ends and act in connection with the xed fence 24. The key 26 is a iiat key and is guided and supported in the usual slottedA hub or barrel 27.

With the parts locked as shown in Fig. 1 the key is turned to lift the tumblers 23 for clearing the fence 24 and to engage the talon 25 of the combined dog and tumbler-carrier, also to swing the said carrier to the right and carry the tumblers bodily therewith until the wing 18 passes from under the wing 17 on the heel of the locking-bolt 10. This releases the lock-bolt, so that the spring 11, acting on the heel of the shackle,swin gs said shackle,which, pulling on the lock-bolt, swings said bolt into the position shown in Fig. 2. With the bolt in this position the heel of the shackle may pass along into its fully-open position when the end of its heel will be in front of the curved face 9 of the bolt and prevent the bolt from being forced to its locking position by pressure on its wing 16 or otherwise until the shackle is so nearly closed as to carry its heel off from the said curved face.

To lock the shackle, it is only necessary to force its nose against the lever 16 of the lockbolt for bringing the shackle and bolt into locking engagement, thereby withdrawing the angular heel 17 from the wing 18 of the dog and tu mbler-carrier 19. The springs 22 press the tumblers downwardly by one of their ends and press the lug 21 of the dog and carrier by their other end. The tumblers, when in the position shown in Fig. 2, are prevented from swinging downwardly under the iniiuence of their springs by their engagement with the fence 24, and consequently when the dog* and carrier 19 is thus released the tumbler-springs act to force the dog and carrier to the left, and in doing so the tumblers and springs are also moved bodily with the said carrier into the position shown in Fig. 1. The wing 18 is in engagement with the heel 17 of the bolt, so that said bolt cannot be moved until the dog and carrier is again forced back. This feature of the tumbler-springs acting to carry IOO themselves and the tumblers bodily along with the swinging dog or carrier is -believed to be a novel mode of operation.

It is apparent that in carrying out my invention some changes from the construction herein shown and described may be made,

and I would have it understood that I do not limit myself to the exact form shown, but hold myself at liberty to make such changes and alterations as fairly fall Within the spirit and scope of my invention. f

I claim as my invention- 1. The combination of the spring-pressed swinging shackle, the swinging lock-bolt, the combined dog and tumbler-carrier also mounted to swing in its case, and a tumbler eccentricallymounted on said carrier,substantially as described.

2. In a lock the combination of the iiXed fence, with the swinging tumbler-carrier, a swinging tumbler mounted on said carrier and a spring serving in a double capacity for moving the tumbler on its pivot and for moving the tumbler-carrier and carrying bodily therewith the said spring and tumbler, substantially as described.

3. The combination of the spring-pressed shackle having the heel extension 8, with the swinging bolt 10 having locking end 15, lever 16, curved face 9 and angular heel 17, the swinging combined dog and tumbler-carrier, having the lug 21, and wing 18, a tumbler mounted on said carrier, a spring 22 with one end acting on the tumbler and its other end acting on the lug 21 of the said carrier, and a fence for said tumbler, substantially as described.
