IMPROVEMENT IN PERMUTATlON-PADLOCKS.
Specification forming part of Letters Patent No. 183,214, dated October 10, 1876; application filed June 2, 1876.
To all whom it may concern:
Be it known that I, DEXTER A. R001, of Bay City, in the county of Bay and State of Michigan, have invented an Improvement in Permutation-Padlocks, of which the following is a specification:
The nature of my invention relates to an improvement in permutation-locks of the hasp and pad class, having tumbler-wheels operated by a dial-knob. The invention consists of the internally-notched tumblers and dialknob, in combination with peculiar indexwashers, for changing the combination, as fully hereinafter explained.
Figure 1, Sheet 1, is a perspective view. Fig. 2 is an elevation of the lock, with the dial removed. Fig. 3 is a similar View, but with the front plate of the case and the dialknob removed, the hasp open. Fig. 4 is a similar elevation to the last, but showing only the inner or last tumbler in position and the hasp locked. Fig. 5 is an inside elevation of the front plate, showing a wire hook introduced under the stop-button, to raise it up to permit the dial to be turned back and taken out. Fig. 6 is a horizontal section of the same at x m. Fig. 7 is a rear perspective view of the dialplate. Fig. 8, Sheet 2, is a vertical section at y 3 in Fig. 3. Fig. 9 is an elevation of the lock, with the dial-plate removed and replaced by a dial struck up on thin sheet metal, for
- the purpose of changing the combination.
Fig. 10 is a rear perspective view of the front plate of the lock. Fig. 11 is a front perspective view of said plate and the dial-plate. Fig. 12- is a perspective view of the inner end of the knob. Fig. 13 is an elevation of a tumbler at either side. Fig. 14 is an edge view of the same. Fig. 15 is a perspective view of the index-washer.
In the drawing, A represents the case of I there is pivoted, by a pin, 0, another part of the same, or a dog, 0, lying nearlyat a right angle therewith. This part 0 has a hook, c, pendent from its free end, and rests upon the tumblers of the look. When their notches come into line, this hook c is thrown down into them by a spring, 01, Fig. 4. A turn of the dial-knob t0 the right at this time would withdraw the hook c from the hasp, and the latter would be thrown out of the case by a spring, f.' At the center of the back plate there is a tubular post, g, flattened on one side, as seen in Fig. 1. On the postis first sleeved a tumbler-wheel, D, Fig. 4, having an internal spur-gear or notches, h, cut in a.
flange on its front edge, and a notch, 'i, in its periphery for the hook c to drop into. Then an index-washer, 70, Fig. 15, is slipped on the post, and its index allowed to engage with one of the notches in the tumbler-wheel. On this is slipped a non-rotating washer, and. then a tumbler-disk, D, is slipped over the post. This disk has a notch, 13, out in its periphery, and a pin, 1, projecting from each.
side, to engage with the index washers k at each side of it. Then a non-rotating washer is slipped on the post, and following it another index-washer, k. The spindle of a dial-knob, E, is then inserted in the socket of the post 9. The base of the knob forms a third tumbler, being notched like the others, and the indexwasher k last put on the post engages with its internally-geared flange.
F is the dial-plate of the case, being circular, with a flange projecting to the front by which to turn it. On the back there are two projecting flanges, m m, which pass through enlargements n n in the circular opening cut in the front plate of the lock, to receive the base of the dial, when, by giving the latter a quarter-turn to the right, it will be locked to the plate. A stop button, 0, pivoted to the front plate, when pushed down by the hasppoint as it enters, serves as a stop to prevent the dial-plate from being turned back, unless the hasp be first thrown open and a hooked wire be inserted under the stop-button, as seen in Fig. 5, to pull it up from behind the flange m of said dial. When the knob is turned, the index'k engaging with it strikes the pin l of the disk D, and rotates that with it until it in turn, through the lower index-washer, sets the tumbler D in motion. When the tumbler D has its notch under the book 0 0f the dog, itis left there by turning the knob to the left until the notch of the tumbler-disk D is in line with it, which disk is left there by turning the knob to the right until all three notches are in line and the hook 0 drops into them, when a slight further movement to the right will free the hasp from the dog.
The changing of the combination is efi'ected by taking ofl' thedial-plate and tumblers and setting the index-washer points into difi'erent notches in the tumblers. To facilitate this a thin dial-plate, 19,21, counterpart of the dial; proper, is provided, which is laid on the face of the case, as seen in Fig. 9, a line, r 'r, being drawn on the case to indicate its proper relative position, in which it is to be held by the thumb of the left hand, after changing ;stantially asdescribed and shown.
