UNITED STATES PATENT OFFICE.
THO. L. PYE, OF NEW YORK, N. Y.
LOCK.
Specification forming part of Letters Patent No. 21,636, dated September 28, 1858i; Reissued October 16, 1860, N0. 1,063.
To all whom t may concern.'
Be it known that I, THOMAS L. PYE, of the city, county, and State of New York, have invented a new and Improved Lock; and I do hereby declare that the following is a full, clear, and exact d escription of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figures l and 2 are internal views of my improvement; the front side of the case being removed, as indicated by the line m, the lock in Fig. 1 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 m, fr', of Fig. 2.
Similar letters of reference indicate corresponding parts in the several figures.
This invention consists in the employment or use of a series of sliding slotted tumblers arranged with a shackel and spring bar, as hereinafter fully shown and described, whereby a very simple and eificient lock is obtained, and one that cannot readily be opened except by the proper key.
The invention is more especially designed for padlocks, but still is applicable to other forms of locks which have a bolt that enters the casing.
To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.
A, represents the case of a padlock, which may be of the usual form; and B is a shackel, which is also of the usual construction and applied to the case A, in the ordinary way. Vit-hin the case A, a series of sliding tumblers C, are placed. These tumblers are each slotted so as to leave a rectangular opening a, made through them, and an adjoining slot Z), the latter extending to the upper edges of the tumblers, so that the sides will form catches b, to work into the eye c, of the shackel, when the latter is in the case and the lock is in a locked state, as seen in Fig. l. The tumblers are placed one behind the other within the case, and their slots a, o, 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be moved to a different distance, in order to bring all the slots in line with each other and allow the shackel to be withdrawn from the case. Each tumbler C, has a triangular or V-shaped projection CZ, at its under side, which projection lits in a V- [FIRST PRINTED 1911.]
`is clearly shown in Figs. l and 2.
shaped groove in a bar D, which has a spiral spring e, bearing against its under side, as Each tumbler C, has an opening f, made through it to receive t-he key E, which key has bits g, projecting from it at opposite sides; said bits being of unequal length, corresponding to the varying positions of the slots a, b, in tumblers C.
The bar D retains the tumblers in proper position, so that the catches b, will be retained in the eye c, of the shackel. The ends of the catches Z2', are rounded, so that the eye when pressed into the case A, will lock itself; said eye pressing aside the tumblers as it enters the slots Z2, and the spring bar D forcing back the tumblers to their original position when the eye c, is in line with the catches 5. To unlock the lock, the key E is inserted in the openings f, of the tumblers; and as said key is turned, its bits g, move the tumblers c, in opposite directions; two moving to the right and two to the left, and the bar D is pressed or moveddownward; the projections el, forcing down the bar, and when the slots I), are in line, the shackel is thrown out from the case; the bar D, by aid of spring c, throwing 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 e, is made to suflice for all the tumblers, on account of the bar D, and the projections cl, on the tumblers C, and the lock is much simplified by this arrangement.
I am aware that sliding tumblers have been previously used, and provided with slots made in them at varying distances apart. Therefore I do not claim the tunr blers separately, but
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
The tumblers C, slotted as shown, provided with projections d, Iand used in connection with a shackel B, or its equivalent, in combination with the bar D, and spring 6,' the above parts being arranged to operate as and for the purpose set forth.
THOS. L. PYE.
