PERM UTATlON-PADLOCK.

SPECIFICATION forming part of Letters Patent No. 585,013, dated June 22, 1897.

" Application filed October 16, 1896- Serial No. 609,099. (No model.)

To all whom it may concern.-

Be it known that I, THEODORE R. VINZENT, of Salem, in the county of Marion and State of Oregon, have invented a new and Improved Permutation-Padlock, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved permutation-padlock which is simple and durable in construction, cheap to manufacture, and arranged to enable the owner to readily change the combination to prevent unauthorized persons from tampering with the lock.

The invention consists of certain parts and details and combinations of the same, as will be fully described herein after and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a perspective view of the improvement. Fig. 2 is a sectional side elevation of the same. Fig. 3 is a face View of one of the tumblers. FigS-" L is a cross-section of the improvement on the line 4 4 of Fig. 2.

Fig. 5 is a side elevation of the several tumblers, and Fig. 6 is a broken perspective view of the bolt.

The improved padlock is provided with two heads A and B, provided with bars A B, respectively, of which the bar B has a reduced end B adapted to engage a correspondinglyshaped socket A formed in the end of the other bar A. From the head A extends parallel to the arm A a sleeve 0, the free end of which abuts on the head B and the said sleeve is adapted to be engaged by a bolt D, projecting from this end of the head B.

The bolt D is provided with a number of lugs D D D placed suitable distances apart and adapted to pass through a longitudinal slot O, formed in the sleeve Q, and into transverse recesses (3 ,0 0 respectively formed in the said sleeve, as indicated in Fig. 2. When the lugs D D D register with the said recesses O O 0 then the bolt D is partly withdrawn from the sleeve 0 andthe reduced end B of the bar B is then out of the socket A to permitof turning the head B, so as t open the bars A and B.

On the sleeve O are mounted to turn the on a shell H, mounted to turn at one end on an offset A formed on the head A, and at its 0, the said collar being formed with recesses 1, adapted to be engaged by pins B projecting from the head B for locking the latter against turning. The key H is. adapted to engage, with the end proj ecting beyond the inner face of the tumbler E, the end F of a bar F held in one of the recesses F formed on the periphery of the tumbler F. The bar F is adapted to be inserted in .any one of the recesses F according to the desired combination, and the bar is held in place in the corresponding recesses by a spring F in the shape of an open ring, fitted into an annular groove F formed at or near the middle of the tumbler F. The bar F has its other end F projecting beyond the other face of the tumbler F, as shown in Fig. 5, and this end F is adapted to engage the end G of a bar G held in one of a series of longitudinal recesses G formed in the third tumbler G". A spring G serves to hold the bar G in place in the corresponding recess G Each of the tumblers E F G is formed at its bore with a recess E for the passage of the lugs D D D of the bolt D, so that the bolt D cannot be withdrawn from the sleeve 0 unless the recesses'E? in the several tumblers registerwith the longitudinal slot C of the sleeve 0. The face of each of the tumblers is marked or graduated, preferably as indicated in Figs. 3 and 4-, a numeral being for each slot, so as tdihdicatethe location of the corresponding bar F or G relatively to the tumblers F and G and the key H relatively to the tumbler E.

It is evident that by the arrangement described the operator can set the key H to engage the desired numbered recess E in the tumblers E, F, and G, separated from each other by collars O secured on the said sleeve The tumbler E is formed in its periphery with longitudinal slots E, one of which is; adapted to be engaged by a key I-I,'formed other end on a collar 1, screwing on the sleevetumbler E, so that the turning of the shell II causes the key 11 to turn the tumbler until its recess E is in alinement with the slot 0'. As the key II is also in the path of the end. F of the bar F it finally moves into engagement with the said end to turn the tumbler F until the latter is brought in position with its notch registering with the slot 0. As the other end F of the bar I?" is adapted to engage the end G of the bar G the tumbler G is turned until its notch comes in register with the slot C. Of course the tumblers can only be turned into these positions if a person knows the combination at which the padlock is set, and when the several tumblers are in this position the head B can be moved outward, so as to disengage the reduced end B from the socket A and permit of turning the head IS, with the bolt D as the spindle, so as to completely open up the bars A and B. The outward sliding motion of the head B with the bolt D is limited by the first lug D abutting against the inner face of the collar I.

It will be seen that by the arrangement described the owner of the padlock can readily change the combination whenever desired, so as to prevent unauthorized persons from tampering with the lock. The shell II is formed at one outer end with a graduation II, reading off on a mark formed on the head A, so as to enable the operator to readily turn the shell II to bring the several tumblers into the proper position for opening the lock, as above described.

Having thus fully described myinvention, I claim as new and desire to secure by Letters Patent 1. A permutation-padlock, provided with a sleeve having a longitudinal slot, transverse recesses leading from the said slot, tumblers mounted to turn on. the said sleeve and formed with recesses adapted to registerwith the slot in the said sleeve, a bolt adapted to engage the said sleeve and having a series of lugs engaging the said slot, and recesses in the said sleeve and in the said tumblers, substantially as shown and described.

2.
