PADLOCK.

SPECIFICATION forming part of Letters Patent No. 304,453, dated September 2, 1884.

Application led December I2, 1883. (No model.)

.To all whom it may concern.'

Be it known that I, WILLIAM WARE Rion- Anns, a citizen of the United States, residing at Vashington, in the county of Wilkes and State of Georgia, have invented certain new and useful Improvements in Padlocks, of which the following is a description.

Figure l is a side Viewr of the padlock unlocked. Fig. 2 is a sectional view with a part oi' the face-plate removed, showing the position of the parts when locked; and Fig. 3 is a longitudinal section through the line w x of Fig. l.

My invention relates' to padlocks in which the shackle-bar is constructed in the form of a circular ring, with an opening or gate in the same formed by a removal oi'a segment of the ring, and into which opening a bolt is made to lock, and through which opening,

when the ring is turned, the shackle-bar is disconnected from the staple and hasp, which it serves to secure.

My invention consists, mainly, in the peculiar form of locking-bolt and its combination with a spring, tumbler, and key, as will be hereinafter fully described.

The frame of the lock consists of two sections, A and B, of which the section A is cast with a curved surface, a, and a central vertical bolt-recess, b, opening into the curved surface, this frame-section being hollowed out on each side at c c to make it lighter. The other section, B, of the lock-frame is formed as a plate with a curved lug, d, at the top, which section, when applied to the section A, leaves between the lug d andthe curved surface c cj room for the circular shackle-bar D. This shackle-bar is a circular ring having an opening or gate atc, which, when turned into the case, receives the lockingbolt, and when turned out of the case acts as a gate or outlet to release the staple, which' is secured by the shackle-bar. E is the locking-bolt, which slides in the middle recess, I), and is backed by a spiral spring, F, which always tends to throw the bolt upwardly and into the opening of the shackle-bar.

In the bottom part of the frame-section A, and in line with the` recess b, there is a swiveling tumbler-barrel, G, through whichQ is formed a slotted opening to receive the key H. The lower portion of the bolt is slotted with a narrow channel-way, f, for the key, and this slot opens at its upper end into wider recess f The key has a flat shank, with a narrow portion at g and awider portion, g', at its end, and the thickness of the flat key is such as to permit it to be passed through the narrow slot or channel-way f.

The operation of this lock is as follows:

`When unlocked, the opening in the shacklebar is outside of the case, as shown in Fig. l. Now, to lock it closed, the shackle-bar is simply rotated until the opening in the same passes into coincidence with the bolt, when the latter, acting under the tension of its spring, jumps into said opening and locks the shacklebar against turning, which shackle-bar, it will be seen, is firmly held between the lug d and the curved surfaces c c. To unlock the shacklebar, the key H is inserted through the swiveling-barrel, an d is passed edgewise through th e narrow part f of the channel-way in the bolt till the wide portion g ofthe key is in the wider recess f-. The key is then turned a quarter of a revolution, when its wide end or bit rests upon the shoulders formed between the wide and narrow portion ot' the channel. The key is then forcibly drawn down and brings the bolt with it, which moves back against the tension of its spring, and in passing out of the opening e on the shackle-bar leaves the latter free tov be turned to disconnect the lock -from the staple. As shown, there is but one recess, f in the bolt, and but one bit, g', on the key; but the bolt may be made with any number of locking-recesses,

and the key may be made with any number ot' I VILLIAM IVARE RICHARDS.
