PATENT OFFICE.
LOCK.
Application filed May 19, 1925,
This invention relates to animproved padlock that is constructed so that the combination can be changed at will without any necessity oi? removing any part of the lock since the combination can be set at any desired series oi numbers or letters and when the lock is ciosed with that setting it can only be openedjat the re-setting of the same combination. C t course, the same combination would be used normally by a person using the lock but if desired the combination can he changed every'time the lock is locked.
The invention comprises a lock of this kind which is constructed so that'the shackle which has an arm in the casing, is held by a tumbler which fits in the shackle and is removable ther trom transversely only when all oi a series of slotted rings andtheir slots are aligned and the operating means for these rings are either in or out 01 operative relation with the operating means according to whether the shackle is in locked or unlocked position.
The invention is illustrated in the accompanying drawings in which Figure 1 is a side view of the lock made according to my invention. Figure?) is a front view thereof. Figure 3 is a central sect-ion taken through Figure 1. Figure 4 is a section on line i-4 in Figure 3. Figure 5 is a section on line 55 inrFigure 3. Figure '6 is a section on line 6-6 in FigureB. Figure 7 is a section on line 7-4? in Figured Figure 8 is a view similar to Figure 8 with the loci: in its unlocked position. a perspective View of the form of tumbler shown in the lock illustrated and Figure 10 is a view showing a ring and an index band therefor, in perspective.
The invention comprises a casing of any suitable form, the casing I show comprising a frame work 10 with a bottom plate 11 and suitable side plates 12, one end of the casing being rounded as at .13 to form a generally cylindrical portion into which the shackle 14 is placed, the shackle having an arm 15 extending down into the casing and movable longitudinally therein to a limited extent. The end 14 of the shackle is held,
when in locked position. in the opening 16 in the casing but when it is unlocked it can be swung around so as to make it easier to release it from an object towhich it is secured. The tubular part 13 has an opening 17in the frontto provide .means for Figure 9 is Serial No. 31,29 Renewed April 7, 1927.
operating the combination which will be hereinafter described.
The arm 15 of the stem has a slot 18 into which fits the tumbler 19. The tumbler is as long as the slot and can be withdrawn laterally therefrom by any suitable means but T show in the drawing a link 20 fastened to an arm .21 which is operable from outside the casing by the finger piece 22. and is held in its normal position by a suitable spring 23. The tumbler can slide to a limit extent on the link 20 and in the form I show it is possible by reason of the rod 24 which is slidable in the eye '25 of the link 20.
Surrounding the arm 15 and also the tumbler when it is within the arm, are rings 26 each ringhaving a slot '27 that can be aligned with the slot 18 in the arm and when all the rings, and in the form I show four of them, are disposed so that their slots 27 are all in line with the slot 18 the tumbler 19 can be withdrawn and the shackle is moved up into unlocked position and .in the form shown this movement is caused by'a spring 28 hearing against thecollar 29 which supports the series of rings 26, the topmost of 'the series resting against the collar or flange 80 or secured to the arm 15 01 the shackle.
Suitable operating means for turning the rings is provided and in the form shown these are typified by the index'bands 31 one of these being. arranged around each ring 26 and having suitable indexmarks 32 which can be placed in register with the index marks 38 on the casing to indicate the combination. I
When the shackle is unlocked as shown in Figure 8 and the spring 28 has pushed the shackle and its attached parts upward, the
The index bands 31- can, therefore,'be rotated to any combination desired and in the form shown it is 8472 and when the proper or desired marks are aligned the shackle is pushed down to its locked position and after it is pushed into the casing the arm 15 withits collar 30 presses the rings down so that the lugs 34 on each ring 26 slide into a recess 36 in its index band 31 and at the same time the tumbler 19 slides into the slot 18 as it is released by the end 37 of the slide 33 entering the slot 39 of the arm 15. The slide 38 is connected with the tumbler by any suitable connection such as the lip 40 slidable in the slot 41 of the tumbler.
lVhen the lock is locked as just described and one or all of the index bands 31 are twirled by passing the finger across them, the index bands turn the rings with them because they are rotatably connected by the lugs 34 and the recesses 36 and the rings have their slots out of alignment with the tumbler 19 and it cannot he slid from the arm 15 of the shackle by its releasing mechanism.
It will be evident that changes can be made in the particular form of parts illustrated herein without departing from the scope of the invention,
It will also be evident from this description that any time it is desired to change the combination the lock is opened, the new combination is set by the freely rotatable index bands 31, the lock is closed and the combination so fixed is the combination for unlocking the lock until by a similar manipulation the combination is again changed. This requires no tools and can be accomplished at any time when it is desired to change the combination.
I claim:
, 1. A lock comprising a casing having a shackle with one arm slidable in the casing, the arm having a slot'therein, a tumbler movable transversely in and out of the slot, a series of slotted rings surrounding the arm and the tumbler and adapted to release the tumbler only when all of the slots in the rings are in line with the tumbler, annular index bands surrounding the rings, and con nections between each ring and its band to permit tree rotation of the bands when the shackle is unlocked and to cause each band to rotate its ring when the shackle is locked.
2. A lock comprising a-casing having a shackle with one arm slidable in the casing, the arm having a slot therein, a tumbler movable transversely in and out of the slot, a series of slotted. rings surrounding the arm and the tumbler and adapted to release the tumbler only when all of the slots in the rings are in line with the tumbler, and annular index bands surrounding the rings, each ring having a peripheral lug and each band having a flange with recesses to rc-- and having connections for operative rotative connection when the arm is locked and for release when the arm is unlocked.
4. A look comprising a casing, a shackle with an arm slidable in the casing, a; trimbler iitting in the arm to hold its against lon gitudinal movement, rings rotatable around the arm and tumbler, the rings having slots to release the tumbler when all the slots are aligned, index bands around the rings and having connect-ions for operative rotative connection when the arm is locked and for release when the arm is unlocked, and a spring for forcing the shackle and its rings to unlocked position when the tumbler is withdrawn from the arm.

In testimony whereof I affix my'signature- 1 CARL ROSENHAHN.
