vTo. all whom 'it 'may concern:

' Be it knownthat we, HENRY F. CRIM and WILLIAM C. LoY, citizens of the United reference,v

f vide a permutation 'padlock structed that access vide a permutation padlock, the interior and working 'parts ofwhch are readily accessibleV 3o 'Stews of `Fulton and State of Indiana, 'vented certain new exact description will enable others skilled in the art towhich it .appertainsto make and 'use the same, being had .to the accompanying drawings,A andtothe. letters and iigures'of reference marked thereon, which form a part 15 of-this speciication.

Our mventfonrelates'to locks, but more` particularly; tofa permutation pad-lock, and as for its object to provide ,a' device of this A iurtherobject of our invention is to pro# which is so concannot be had to the interior of the lock so long as the same is 'in a locked position.

Afurther object of our invention is to prwhen t e shackle is-in an unlocked position, in such manner that the combination ofthel lock can 4be readily changed at any time, and

this can be accomplishe without the use of tools or instruments and without disguring the lock in any way.

' With these objectsin view our invention j Vcc'msists in the combination of thelock casing,

will be herein-' after' fully described and specifically pointed i Fi 'that the'wall 10 of the casing is sinnshackle, tumblers and cap as out in the appended claim.'

Referringto the accompanying erspective' view. of 'our penna;

Figure 1 is a tation lock.- same. Fig 3' 1s at'op'p an view slic'xwingl shackle in an unlocked position. Fig. 4 is a similar view showing shackle in an unlocked position and illustrating the-screw capor top swung out of its norma position. Fig. 5 is a' plan view of the three circular ,tumblers 6 is a plan view showing casing with tumblers removed, .and Fig. longitudinal-sectional view through the lock.

Like numerals of reference indicate the same parts throughout' the several figures -in which;

class which is particularly simple in denonstruction, cheap and 4easy to manufacture',-

and strong'and durable.

shown 1n Fig. 6.

ig. 2 is ato plan viewgof the 7 is a vertical 1 1` indicates the pad-lock comprising the body or casing 2, .said body or casing beingl provided with an extension 3 to whichthe 5. Except for the shackle 4 is pivoted at extension 3 it will be seen that the body oi" casing 2 is circular, and by referrin to Figs. 6 and 7 it will be seenthat thesaiddiody 2 is recessed tumblers 7 8 and 9, the annular wall 10, face 11 and extension 3 .beingintegral-and 'preferably'formed out of a solidpiece 'of metal.

at 6 to accommodate the circular Upon the `face 11, as shown in Fig. 1, is

-formed a dial 1 2, said dial being provided with a series of-'numbers from one to twelve or more, and around the edge of said dial are provided a series of slight grooves or indentations incide with numberson the dial.

so to said 'shaft 15, by means of which button the pointer 14 moved over the face of theldial.

Secured to the 'shaft 15 or formed integral therewith and on the inside of the casing is a disk 17, said disk' being provided around its periphery with a seriesD of notches 18 as Referring to Fig."5, which illustrates the circular tumblers, it'will be'seen that the tumbler'7 is provided with a lug 19 upper face and ya similar lug 20 on its lower face, said lug The tumbler 8 is also provided with an upper and a lower lug 21 and 22; while the tumblei- 9 is provided only with a lower lug 23.

' It will also be seenfrom Fig. 5 that a portion of the periphery, ofeach 'of the tumblers, is cut away, forming in each tumbler a notch 24, and in this connection it will be seen from lar y cutaway at 25,'the notches 24 in the tumbler forming substantially a circular opening in connection with the cut away portion 25 in the wall '10 of the casing.

l11i indicates a pointer carriedon a'shat orspindle 15, and 'i6-isa turn button secured a on its 20 being shown in dotted lines. f

13, which groovesor indentation's co- '26 indicates the threaded cap or topoi the lock,.whicl 1as shownin Fig. 7 is provided with a flange 27?, said fiange being threaded, While thewall 10 of the casing is also threaded to receive said ilange.' A'. central tube 2S carried on the cap 26 accommodates the two circular tumblers 8 and 9, as shown in Fig. 7, While the lowest tumbler 7 is journaled on thefshaft 15 which isrotated by the turn button 16, as shown in ig. 7.

Referring seen that the threaded top' or cap 26 is cut now to Figs. 3,Y and 4,it will be away at 29 allowing the end 30 oi the shackle -to enter thelock, as shown in Fig. 7", .said end 30 of the shackle being` provided with three transverse 'grooves 31 within which the turnblers 7, 8 and 9 enter,` as shown in Fig. 7. i Having thus fully describedour invention, its operation is as follows: The .lugs having been assembled, the circular tumblers 7,. 8

and 9 are rotatedby means of the. turn button 16 on. the dial and 'any movement imparted to the turn button 16 rotates the disk 17 on the inside of the lock, andthe lower or underlug 2O 'on the tumbler 7 beingv in engavement with one of the notches 18 in said dis 17, as shown in Fig. 7, said tumbleris y,necessarilyT rotated in either direction; rthe central or intermediate tumbler' Shaving its lower lug 22 directly inthe path ,of the upper lug '-19 on the'tumbler-Z vsaid''tumbler Sis` rotated when'the lugsv 19 and 22 come t0- getherythe central. tumbler 8 being provided withan upper lug 21 andthe tumbler 9 being'providd with a lower lug 2 3, said` lugs being in the saine path the said tumbler .9 isrot'ated by the tumbler Swhen the said tln'order to unlockt e locker-release' theY i shackle 4 from engagement with the tnniblersf itis necessary that every one of the notches 24 inthe tnrnblers ,7,8 and 9 registerone above the other, and unless these; turriblers ht into this positionlon'eor more of' l and "thereby hold, the/shackle in a locked p'osition. The tumbles' are .placed ,within4 the lock so that the pointer 1 4 have .to
