.To .all whom-it may concern.'

Be it known that I, JACOB I-InNDRionsoN,

a -citizen of the United States, .residing at Northport, in the county of Stevens and State of Washington, have invented a new and useful Permutation-Padlock, of which ithe following is a specification.

rThe present invention appertains to a permutation padlock, and .aims to provide Va -novel and limproved device of that character.

It is-the object Aof the present invention to provide -a' permutation or combination padlock, embodying a shackle and manually controllable tumblers within the padlock case, for normally maintaining the shackle in closed position, and for permitting the shackleto be slid when lthe tumblers are set properly.

A further object` of the present invention is to provide a :padlock of the nature indicated, wherein means-are provided whereby.

vchanges in the combinations of the tumblers may be eii'ected ina simple and convenient manner.

With the foregoing and other-objects in view, which will appear as the description proceeds, Vthe invention resides in the combination and-arrangement of parts and in 0 lthe details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention. The invention has -been illustrated in its preferred embodiment in the accompanying drawing, wherein of Fig. -2.

In carrying out the present invention, there is provided a ysuitable padlock case 1, which has its sides orfaces, bottom and top split or divided, to provide the ytwo sections 2 and 3, which have their bottom or lower end portions hinged together, as at E4, whereby the sections of the case may be :swung open and closed. 'The lower end or lbottom .portionof-the--section 3 preferably projectsl 'beyond the-sideor back portions,

.asnseen :in Fig. l', whereby the face or side portions of the section 2 may overlap the saidprojecting lower end or bottom portion when the sections are .closed or folded together, l

The face -orside portions of the section 2 are preferably larger or greater in extent, than those of the section 3, the sides or faces yof the case being divided at one side of the center of the case to` that end. Spindles or arbors v5 are journaled through the 'face or side portions of the section 2, centrally of the case, and have lknurled heads or knobs 6 at their outer or remote ends for permitting thespindlesor arbors to be readily rotated Aby hand.

Secured .to the inner ends of the spindles or arbors 5i, is a pair of tumbler disks 7, which have the inner bosses or hubs 8 keyed or .otherwise engaged upon the inner ends of the-spindles, it being preferable to pro- -vide the bosses o r hubs 8 with square or non- .circular vopenings engaging over the squared 0r non-circular inner ends of the spindles 5. The .tumbler disks 7 are provided with :the inturned or inwardly projecting marginal or peripheral flanges 9 which have their edges spaced slightly apart, each of the flanges or lips 9 being provided with a chordal notch or slotyfl() for the purposes which will hereinafter appear.

A dial disk 11 is mounted rotatably upon each of the vspindles or arbors 5, between the corresponding tumbler disk 7 and face or side of the case, the dial disks being slightly larger in diameter than the tumbler disks, so that their peripheral vportions project beyond the tumbler disks. The outer or remote sides ofthe dial disks are provided with graduations or indicia along the Inargins or peripheries of the said disks, and the face or side portions of the section 2 of the ca-se areprovided with openings or slots l2 adjoining the upper end or top of Jche case, through which the graduations or 1ndicia are visible from the outside, for enabling the tumbler disks to -be set properly, as will hereinafter more fully appear.

In order to adjustably connect the dlal disks 11 tothe tumbler disks 7 each of the dial disks is provided with an annular serres of apertures 13, which .are confined within the faces or sides of the case, when the case is closed, ascrew or key 14 being passed :through one ofthe .aperturesl-B of each dial disk and takinginto the threaded aperture 15 provided in the corresponding tumbler` disk. lt is evident, at this point, that each of the dial disks is made fast to the corresponding tumbler disk, by thel clamping screw or key 14, whereby the dial disks will be rotated with the tumbler disks, when the 'shafts or spindles 5 are rotated. It will also be evident that by withdrawing the screws or keys 14, the dial and tumbler disks may be rotated or swung with respect to one another, in order to change the combinations as will hereinafter appear, the screws -or keys 14 being passed through the proper -apeitures 13 so as to again engage he apertures 15 of the tumbler disks. Y

The free end or top portions of the sections 2 and 3 of the case, are provided with interengaging or intertttingv lugs or projections 16 whereby, when the sections are closed, they will be locked against springing or shifting laterally relative to each other, which would be objectionable.

. A latch o-r catch 17 is pi `otedl upon the free end or top of the section 2, adjoining one face or side portion thereof, and is adapted to swing over the upper end or top of the section 3, when the two sections are swung together, to thereby retain thecase in closed condition, under ordinary conditions.

The shackle 18 of the padlock, is of U- shape, and has a reduced extension 19 at one end which is' insertible into or through the socket or aperture 20 formed in the upper or free end of the section 2,- the extension or finger 19 being relatively short, so as not to engage the tumbler disks when the extension 19 is inserted through the aperture 20. Projecting from the other end of the shackle 18, is a relatively long projection or shank l21 which passes through an aperture or bore 22 formed in the upper end or top of the section 3 of the case, and which has its sides flattened, as at 23, from a point spaced from the end of the shackle 18, to apoint short of the free end of the shank 21, to provide the head or shoulders 24 at the free end of the said shank. The shank 21 is lprovided with a longitudinal slotl 25, and a retaining pin 26 is engaged through one side of the section 3 adjoining its upper end, in order that the yinner end of the pin 26 will engage theslot 25 so as to permit -the shackle to slideA inwardly and outwardly to a limited extent, but `preventingthe shackle from being removed, unless the pin- 26 is withdrawn.

The projection or shank 21 is of such a length that the head or shouldered portion 24 is proj ectable through the slots or notches 10 of the tumbler disks, when the said slots or notches are swung in alinement with the aperture or bore 22, in order that the head or shouldered portion 24 may lock within the flanges 9 of the tumbler disks under certain conditions, that is, when the tumbler disks are so swung, that the slots or notches 10 are out of alinement with the aperture or bore 22 to break up the combination.

In use, when the sections of the case are folded together, or closed, those portions of the dial and tumbler disks projecting from the section 2, as seen in F ig. 1,y will be housed within the section 3, the graduated portions of the dials being exposed through the openings or slots 12 in the sides or faces of the case. When the tumbler disks are swung to the proper positions, whereby the channels or slots 10 aline with the aperture or bore 22, this being readily accomplished by bringing the proper numerals or indications within the openings 12, will enable the shackle to be opened and closed. Thus, supposing the shackle to be opened or slid outwardly, the projectionor finger 19 being disengaged from the aperture or socket 20, and the projection or shank 21 being drawn outwardly out of engagement with the tumbler disks, to close or lock the shackle, it is merely necessaryto slide or force the same inwardly so that the projection `or finger 19 enters the aperture or socket 20, and so that the free or headed end of the shank 21 passes through the slots or notches 10 of the tumbler disks, to bring the headed' or shouldered portion 24 within the annular lips or anges 9. Then by'disarranging-the tumblers, by rotating the spindles or shafts 5, the flanges or lips 9 will engage over'the head or shouldered portion 24 of the shank 21, and will thus lock the shackle in closed position, the shoulders of the head or portion 24 engaging under the lips or flanges 9.

from between the tumbler disks. Thus, the

finger 19 may be withdrawn from the aperture or socket 20 to open the shackle, whereby the shackle may be detached from or applied to a hasp keeper, or any other object, the present device being employed in the same capacities as an ordinary padlock.

The pin or key 26 engaging the slot 25 of the shank 21 will prevent the shackle from being rotated, and will also limit the outward movement of the shackle,in order that the same cannot be detached, although it may be slid to the necessary extent in opening and closing the shackle.

Ordinarily, when the case is closed, the latch 17 is engaged to the free end of the section 3 of the case, and will lock the sections in closedposition.l To change the comdial disks.

bination of the lock, the sections 2 and 3 are opened, by iirst opening the shackle 18 so that the extension 19 is released from the section 2, the latch 17 also being released from the section 3, to permit the two sec-` tions to swing apart or unfold as suggested in Fig, 1. Then, by withdrawing the screws or keys 14, after the same have been eX- posed, as seen in Fig. 1, the dial disks may be set to dierent positions or to the new positions desired, in which event, the screws or keys 14 may be passed through the apertures 13 alining with the apertures 15 of the tumbler disks, to engage the said apertures 15 for againsecuring the dial disks to the tumbler disks. Thisenables a large number of combinations to be had, according Ato the number of indications upon the After the dial disks have been readjusted or reset with respect tothe tum- .bler disks, the sections 2 and 3 may be closed, and the latch 17 then engaged to the free end of the section 3 to lock the sections together under ordinary conditions when it is not desired to open the sections of the case.

From the foregoing, taken in connection with the drawing, the advantages and capabilities of the present device will be obvious to those versed in the art, without further comment, it being noted that the objects aimed at have been carried out satisfactorily,

Having thus described the invention what 1.
