gwvantoz [ffii] .ff/Wikia* Patented Aug. 19, 1930 UNITED STATES PATENTl OFFICE EMIL SCHEIBNER, F PATERSON, NEW JERSEY PERMUTATION PADLOCK Application filed December 22, 1928.

Serial No. 327,820.

1'7--17 adapted to engage in notches 18-18 in the entered ends of the shacklebolt 12 and are pressed into engaging positions by springs 19-19 disposed in the recesses 14-14.

' Passing through the inner shorter ends o f the levers 15-15 is a rod 20 on which are fixed collars 21-21 in contact with the levers, the'rod drawing the collars thereagainst by a coiled tension spring 22, one 60 of its ends being fixed to a projection on the rod 2O and the other attached to a lug 23, which, with the casing en d, acts to support and guard the rod.

The outer, rounded edge of the body 10 65 is machined to present a plurality of equally spaced uniform parallel slots 24a-24b-24L- 24d-24e-24 suited to receive discs 25a- 25b-25c-25d-25e-25, having on their circumference numerals reading from 0 to 9, 7o inclusive, these discs containing axial bores as at 26.

These several bores have polygonal recesses 27 in one side of the discs and fitted to enter therein are correspondingly shaped flanges 75 27 extending from sleeves 26 adapt-ed to enter the disc bores. i

Each sleeve contains a key-way as 28, through which may be passed a pin as 29a- 29b-29c-29d-29e29f, all being fixed ina so straight row in a spindle 30 having an extending knobbed head 31.

The spindle passes into the body from one of its end edges to have threaded upon it the several sleeves, the inner, reduced end of the 85 spindle having a bearing in an inreaching lug 32, its extremity making contact with the longer end of a lever 33, pivoted at 34, within the chamber 13, the shorter end 0f the lever being pivoted at 35 to the inner end 9o of the rod 20.

From the foregoing it Will be seen that the shackle 12 may be entered and engaged within the lock at any time quite irrespective of the position of the discs or pins on 95 the spindle, the springs 19-19 yielding to permit such engagement.

However, in order to release the shackle 12 the detent levers 15-15 must be retracted which is accomplished by the pull spring 22 100 padlock.

On such locks the liability of loss of a key is avoided because none is used; furthermore a greater degree of security is attained as the lock bar cannot be released except by persons familiar with the combination at which the discs are set, and each disc is capable of being changed so that a wide range of combinations may be made.

The foregoing advantageous object, together with others, such as compactness, simplicity and ease of operation are accomplished by the novel construction, combination and arrangement of parts as hereafter described and illustrated in the accompanying drawing, constituting a material component hereof, and in which Figure 1 is a sectional view of an embodiment of the invention, shown in locked position.

Figure 2 is an edge view of the lock.

Figure 3 is a transverse sectional view taken on line 3-3 of Figure 1.

Figure 4 is a partial side elevational view of the lock.

Figure 5 is an expanded view showing in perspective certain of the discs and spindle.

Figure 6 is a side elevational view of one of the permutative sockets as removed from a disc.

The body 10 of the lock is rectangular in profile and narrow in cross section, curved at its outer longitudinal edge, square in its opposite edge which contains two spaced apart openings 11 and 11, the same being receptive of the ends of a shackle 12.

Within the body is a chamber 13 with which the openings 11-11 communicate and on one side `of the openings are recesses 14 and 14 into which levers 15 and 15 extend, these levers being pivoted on pins 16 and 16 in the walls of the chamber 13.

The levers 15 have lock elements the when the spindle 30 is drawn slightly outward.

Obviously the spindle can not be retracted unless all of the several sleeves are so positioned as to cause alinement of their slots or keyways, obtained by turning the discs into a nown osition ascertained by their numerals'mnli) as each :libc is ea ble of several permutations by changing he position of the sleeves therein, a vast combinations may berbtained The fore oing disclosure is to be regarded as descriptlve and illustrative only, andnot as restrictive or limitative of the invention, of which obviously an'embodiment may" be constructed including.. many modifications Without departing from the general scope herein indicated and denoted in the appended claims.

Having thus described my invention, what I :chimes new and desire to secure by Letters Patent, is
