THOMAS L. PYE, OF NEW YORK, NZ'Y.

IMPROVEMENT IN LocKsQ Specification forming part oi Letters Patent No. 21,6%,` dated September 28, 1858; Reissue No. 1,063, dated October 16', 1860.

To all whom it may concern Be it known that l, THOMAS L. Prin, of the city, county, and State of New York, have in-` vented a new and Improved Lock; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specification, in whicht FiguresV l and 2 areinternal views of my improvement, the front side of the case being removed, as indicated by the line fr x, the lock in Fig. l being shown in a locked state and in Fig. 2 in an unlocked state. Fig. 3 is a section of the same, taken in the line w fr of Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures. f The nature of my said invention consists in a series of tumblers moving in reverse directions in combination with a key having bits on two sides, whereby some tumblers are moved in one direction and others in the other to bring the notches or openings to the correct point for receiving or liberating the shackle or stud of the bolt or latch, whereby a very l simple and efficient lock is obtained, and one that cannot readily be opened except by the proper key.

rlhe invention is more especially designed for padlocks, but still is applicable to other forms of locks.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the case ot' a padlock, which may be ofthe usual form; and B is a shackle, which is also of the usual construction, and applied to the case A in the ordinary way. Within the case A a series of sliding tumblers,' C, Iare placed. These tumblers are each slotted so as to leave an opening, a, made through them and an adjoining slot, b, the latter extending to the upper edges of the tumblers, so that the sides will form catches b', to work into the eye o of the shackle when the latter is in the case and the lock is in al locked state, (as seen in Fig. l. rlhe tumblers are placed one behind the other within the case, and their slots a b are 'made in them at varying distances apart, so that each tumbler will'require to be moved to a different distance in order to bring all the slots in line with each other and allow the shackle to be withdrawn from the case. Each tumbler O has a triangular or V-shaped projection, d, at its under side, which projection ts in a V-shaped groove in 'a bar, D, which has a spiral spring, e, bearing against its under side, as is clearly shown in Figs. l and 2. Each tumbler C has an opening, f, made through it to receive the key E, which key has bits g projecting from it at opposite sides, said bits being of unequal length,

corresponding to the varying positions ofthe slots a bin tumblers O. The bar D retains the tumblers in proper position so that the catches b will be retained in the eye o of the shackle. The ends of the catches Zn are rounded,

so that the eye c, when pressed into the case A, f

will lock itself, said eye pressing aside the tumblers as itienters the slots b, and the springbar D forcing back the tumblers to their original position when the eye c is in line with the catches b.

To unlock thelock thekeyE is insertedin the site directions', two moving to the right and two to the left, and the bar D is pressed or moved downward, the projections d forcing down the bar, and when the slots b are in line the shackle is thrown out from the case. The bar D, by aid of spring e, throws the tumblers back to their original position, when the key is withdrawn or is slightly turned back by the hand.

By this improvement one spring, o, is made to suffice for all the tumblers, on account of the bar D and the projections d on the tumblers (l, and the lock is much simplified by this arrangement.l

It will be evident that my invention maybe adapted to different kinds of locks, as aforesaid, so long as the key with bits on opposite sides is combined with tumblers moving in the reverse direction to liberate the bolt, as set forth.

What I claim, and desire to secure by Letters Patent, isx 2. A series ot' tumblers provided with open- .ings or notches, into .which the shackle or stud of the bolt passes, in combination with a key having bits on opposite sides, by the turning of which said tumblers are moved in reverse directions to bring the notches'or openings into line for receiving or liberating In witnesswhercof I have hereunto set my the shackle or stud of the bolt, as set forth.` signature this 10th day of September, 1860.

2. A V-shaped sliding bar and spring, com- THOS. L. PYE. bined with said reverse moving tumblers, to Witnesses: restore them to a normal position when the THos. GEO. HAROLD, key is not in action, as set forth.. LEMUEL W. SERRELL.
