U ITED A PATENT OFFICE.
AGHILLE PARISE, OF NAPLES, ITALY.
IMPROVEMENT IN COMBINATION-LOCKS.
Specification forming partof Letters Patent N 0. 186,268, dated January 16, 1877; application filed December 23, 1876.
To albwhom it may concern ,Be it known that I, AcHILLE PARISE, of
the city of N aples,;Italy, have invented a new i and Improved Combination-Lock, of which I Fig. 4, a vertical transverse section online a c, Fig. 2, of my improved combination-lock.
Similar letters of reference indicate corresponding parts.
The invention relates to an improved combination-lock for doors, trunks, safes, 850., that admits, by simple construction, a large number of combinations, and may be opened and closed in quick and convenient manner.
The invention consists of sliding tumblerplates, having longitudinal slots and a number of perforations placed at differentrelative positions to the slots of each tumbler. The trunks are connected by screw set-pins attached to face-slides, and passing through any one of the perforations, admitting the setting of the tumblers and opening of the look by outer projections or buttons of the slides to fixed exterior guides.
In the drawing, A represents the casing of my improved combination-lock, which may be made of any thickness and size, according to the purpose for which the lock is to be used. Any suitable number of sliding tumbler-plates B are arranged inside of the casing A, said tumblers having central or side recesses a for the entrance of the bolt, as desired. The central recesses ahave slotted extensions b,
which admit of the sliding in and locking of the tumblers to the bolt or catch. When the recesses are at the ends to be used in connection with a sliding bolt with extension-plates, the latter are prevented from being drawn back when the tumblers are not in the required position. Each tumblerB is provided with as many longitudinal slots d as there are tumblers, minus one, and also with a suitable number or series of perforations, e, which takes the place of a slot. The perforations and slots of all the tumblers register with each other, and are so arranged that the relative position of perforations and slots is difi'erent in each tumbler, the first tumbler having, for instance, the perforations above the slots, the second having one slot above, the other slots below the perforations, the third, two slots, and the others below, and so on, according to the number of tumblers.
The perforations e of the tumblers are preferably numbered symmetrically to the center same. The face slide-pieces D and guides D are either ribbed, as in the drawing, or provided with projections, lugs, or buttons, for the purpose of readily moving the slide-pieces and thereby the tumblers. V
The uniform grooving of the guide-pieces and slides, as shown in Fig. 1, is mainly intended for the purpose of rendering any attempts to open the lock futile and more difficult.
The tumblers are set by means of the slides to the ends of the guide-pieces, which serve as indicator-points, as many of the divisions or gradnations of the slides being moved either to the right or left of the ends of the guidepieces, according, as the corresponding screw set-pins are inserted into perforations at one side or the other of the center holes. When the slides are thus set to the correct figures, to which the screw-pins are secured, the recesses of all the tumblers will be in line with the bolt, so as to admit the detaching or sliding back of the same. The number of combinations increases with the number of tumblers and perforations of each tumbler, the latter, however, being limited by the length of the slots of the casing in which the slidepieces or screw-rods are allowed to move.
For satchels,trunks, and similar articles,-
dling and tampering as the common key-locks at present in use. The lock may also, in place of the sliding tumblers, be constructed with round tumblers turning on a center pivot, and having concentric slots and per-- forations for set-screw rods. This construc-' tion may be preferable in some cases, as less space is taken up thereby, the construction and operation being in other respects analogous to the lock with sliding tumblers.
- Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. Asz-combination-lock consisting of a number of recessed tumbler-plates with longitudinal slots and a series of perforations, and of ra ua ed a e sl deieces set o f ce guidepieces by screw set-pins passing through 'the slots and one of the perforations of each'tumbler, to be operated and adjusted substantially as and for the purpose set forth.
2. ln a combination-lock, the sliding or turning tumbler-plates. having as many slots, less one, as the number of tumblers in the lock, and a series of perforations arranged in each tumbler symmetrically to a central perforation, substantially as and for the purpose described.
3. In a combination-lock, a sliding or turning tumbler having as many parallel slots, less one, as the number of tumblers in the lock, and a series of perforations for the passage of the screw set-pins, said perforations registering with the slots of the adjoining tumbler, and having a different relative position to the slotsin each tumbler, substantially as and for the purpose set forth.
