UNITED STATES PATENT OFFICE.
SADER H. LEIKVOL, OF APPLETON, MINNESOTA.
PERMUTA-TloN-PADLOCK.
SPECIFICATION forming part of Letters Patent No. 265,107, dated September .26, 1882.
' Application filed July 7, 1882. (Model.) g
To all whom it may concern Be it known that I, SANDER H. LEIKVOL, of Appleton, in the county of Swift and State of Minnesota, have invented certain new and usefullmprovementsin Combination-Locks and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a view, with one side of the lcase removed, of my improved permutatioulock. Fig. Il is a cross-section thereof through line x x, and Fig. III is a section taken at right angles to the aforesaid section.
This invention relates to an improvement in permutation, otherwise termed combination,77 locks, which is simplein construction, cheap, and easy ofoperation; and it consists in the combination and arrangement of Y parts substantially as hereinafter more fully set forth and claimed.
To carry out my invention I construct the ease A with a circular chamber, A'.
B is the dial or disk, having a series of circularly-arranged numerals thereon, and disposed ,upon a spindle, C, next to the front plate of the case A. The shaft or spindle C, with which the dial turns, bears in. the front plate of the case A and passes through the chamber A', its opposite end resting in the` back plate of the case A. i
B' B2 B3 B4 are circular or annular tumblers, which consist each of a ring of suitablemetal. The spindle C has a tongue or projection, b, within the chamber A', preferably made in the f orm of a bail onstaple, and a knob, c, on its outer end,beyond the case A. Each of the ring-formed tumblers, which move in grooves in the circumference of the chamber A', has a projection upon its inner circumference. lThe projection D of the ring B traverses about two-thirds of its inner circumference, the projection D of the ring Bz about one-half of its same surface, the projection D2 about onefourth of the inner circumference of the ring B3, and the projection D3 about one-sixteenth of thesame circumferenceof thering B4. This arrangement of theprojections upon said rings or tumbler-s permits the latter to be acted upon separately and at different intervals by the projection or tongue b of the spindle C. In the outer circumference or periphery of each tumbler, including the disk B, is a notch, c', to receive and permit the sliding backward of the staple or bolt securing bar when the operation of unlockingis being performed. Vhen the notches c are in line with each other no vone of the projections of the tumblers is in line with the others, and each tumbler has an independent movement. Therefore, as said projections are acted upon by the tongue or projection of the spindle, said notches will be moved out of line with each other and with the shoulderor projection of the staple or bolt securing bar, and thus efl'ect the locking operation.
E is the bolt or staple securin g bar orslide, arranged to slide in a passage, d, in the case A, at one side of the pivotal or hinged point of the staple or bolt F. This bar has beyond this point a laterally-extended portion, Fi', having movement in a recess, d', openinginto the chamberA. Theextension E hasadown- Ward-projectin g tooth or lip,c, which bears upon the periplieries of the tumblers when the bolt ,is in a locked position, but drops into the peripheral notches c thereof when performing the unlocking operation. The forward end of the bar or slide E projects into a socket, j', in the case A, which receives the apertured end Gr of the bolt or staple F of the lock, and enters the apertureof said staple or bolt to effect the locking operation.
\ To perform the locking operation according to the combination as adopted at this time, it being capable of being changed by adjusting or changing ,the position of the tumblers with relation to one another, the following directions are observed: Turn the kncbbed spindle to the right until'the numeral 4 of a series of numbers marked on one side of the disk or dial-B can be viewed through an aperture, g, in the front plate of the case A. Then turn it to the left until the ordinal 2 comes into view. Next again reverse its movement to bring to view the numeral 8. Then turn in an opposite direction until the ordinal 1 comes into View,
roo
and,nally,turn back until the number l2 can be seen.v4 Now pull outward upon the slide or bar E, when the staple or bolt can be Withdrawn. It is obvious that by inserting the free end ot the staple or bolt and pushing n- Ward theslideor barEztnd turning theknobbed spindle in either direction the looking operation can be readily performed.
I claim and desire to secure by Letters Patent ofthe United States- 1n upermutzttionlook,theoombiuation, with the oircularlyohambered oase having the apertured front plate and the apertured staple or bolt, of the circular notched tulnblers having the varying-sized projections upon their inner oirournferenoes, the tongued spindle, thel slide or bnr having the tooth or projection bearing upon the peripheries of the tumblers and adapted to connect With the staple and the dial B, substantially as specified.
In testimony that I claim the foregoing as my own I have hereunto alixed my signature in presence of two Witnesses.
SANDER H. LEIKVoL.
