" PERMuTATloN-LOCK.
SPECIFICATION forming part of Letters Patent No. 431,450, dated July I, 1890. pplication filed November 18, 1889. Serial No. 330,706. (No model.)
To all whom t may concern.-
Be it known that I, BYRON J. DoUDs, of Kent, in the county of Portage and State of Ohio, have invented certain new and useful Improvements in Permutation-Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which .it pertains to make and use the same.
My invention relates to improvements in permutation-locks, and is designed as an improvement on a lock for which United States Letters Patent No. 896,273 were granted to me January l5, 1889, and to which reference 1s made.
The improvement consists, essentially, of a tumbler for locking the bolt, such tumbler being actuated and in turn locked by the vibratlng lever of the permutation mechanism, to the end that the lock patented as aforesaid 1s thereby adapted to mortise-locks and such other locks. as are provided with knob and knob-spindle for actuating the bolt. u
In the accompanying drawings, Figures l and 2 are corresponding plans with the cover of the casing removed and showing the position o f parts with the bolt and tumbler, respectively, in position locked and unlocked.
A represents the casing, which in the present instance is designed for a mortise-lock; but of course this casing may be varied to adapt the lock to other varieties.
B represents the knob spindle, having mounted thereon hub b, the latter having arms b projecting in opposite directions for withdrawing the bolt in turning the knobspindle in either direction.
C is the bolt, the same being' of the forked variety shown, the prongs thereof embracing hub b, and each prong having a toe c for engaging arms b aforesaid. The bolt is shot by the action of spring c', the parts thus far described being of well-known variety.
D is the tumbler, pivoted at D', the tumbler being notched at D2 to pass astride the adjacent arm b for locking the bolt. Thetumbler is blocked in such locking position, and is actuated in moving to and from such locking position by means of vibrating lever E, the latter being pivoted at E. The lever 'cam-shaped at e'.
is provided with a curved end e, the face thereof being concentric with the axis of the lever, such curved end engaging a corresponding seat or ledge d of the tumbler, the arrangement being such that the lever may vibrate a considerable distance, meantime blocking the tumbler in position and locking the bolt mechanism. The re-enforcing block d2, that is planted on the body of the tumbler,
the one edge thereof constituting seat (l aforesaid, is cut away cam-shaped at cl', and the extreme or toe of the lever is correspondingly Vhen lever E is moved outward to the eXtrem e of its throw, the curved end e of the lever is withdrawn from seat d of the tumbler, and simultaneously therewith lever E engages pin or stop cl3 of the tumbler, by which engagement the tumbler is retired to the position shown in Fig. 2, in which position of parts the bolt mechanism isleft free, and the bolt may be withdrawn by turning the vknob-spindle in either direction. When lever E is reversed or moved inward, cams d e being, if not in actual contact, in close proximity to each other, the engagement of these cams, caused by the rst slight inward movement of the lever, returns the tumbler to its locking position, (shown in Fig. 1,) and a triiie farther inward movement of the lever blocks the tumbler in such position, the blocking of the tumbler following almost instantly the shifting of the tumbler. The shifting inward and outward of lever E, caused by the engagement of the different cams of disk F with pin e2 of the lever, is fully shown and described in the aforesaid patent, and therefore need not be repeated. I will add, however, in the Way of a general explanation, that the arrangement is such that the disk having been turned forward and back, according to the combination thereon, a point will eventually be reached-such, for instance, as at fwhere the cams, by engaging pin c2, move the lever outward to the extreme of its throw for unlocking, and that when the disk is turned one notch from such point in either direction the lever is shifted inward far enough to return and block the tumbler in its position, securing the bolt mechanism.
The construction of the tumbler with a reenforcing block, as shown, is a mere matter of convenience, and the tumbler could be constructed in one piece, if preferred.
What I claim isl. In a permutation-look, the combination of rotating cam-disk and vibrating lever actuated by the cams of the disk with bolt and vibrating tumbler for looking the bolt mechanism, the said lever and tumbler having mutually-engaging members, substantially as indicated, for looking the tumbler pending the manipulation of the earn-disk and for shifting the tumbler with the extreme movements 1 of the lever at the terminal of the permutation combination, substantially as set forth.
2. In a look, the combination, with a disk having a series of cams thereon, and avibrating lever engaged by the cams on the disk, of tumbler engaged and operated by said lever, substantially as set forth.
In testimony whereof I sign this specification, in the presence of tWo Witnesses, this 9th day of May, 1889.
