OKLAHOMA TERRITORY.

COMBINATION-PADLOCK.

SPECIFICATION forming part of Letters Patent No. 595,650, dated December 14, 1897.

Application filed August 30 1897. Serial No. 650,006. (No model.)

To all whom it mag concern:

Be it known that I, HENRY A. REDMAN, a citizen of the United States, residing at Guthrie, in the county of Logan and Territory of Oklahoma, have invented a new and useful Com-' bination-Lock, of which the following is a specification. Y

My invention relates to combination-locks, and has for its objects to provide a simple, strong, and durable construction and arrangement of parts, including the efficient mounting of rotary tumblers when used in connection with a lock of the class wherein a shackle is employed, and also to provide simple means for changing the combinations.

, Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a view of a lock constructed in accordance with my invention. Fig. 2 is a central sectional view of the same. Fig. 3 is a detail view in perspective of the frame of the lock, the tumblers being omitted. Fig. 4 is a detail view in perspective of the shackle detached. Fig. 5 is a similar View of one of the tumblers detached. Fig. 6 is a transverse section of one of the tumblers and the leg of the shackle.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

The body portion or frame of the lock embodying my invention consists of upper and lower caps 1 and 2, connected by front and rear connecting-cheeks 3, the upper cap being provided with twin shackle-leg openings 4, and the lower cap being provided with sockets 5, alined respectively with said openings. Arranged between the upper and lower caps and axially alined respectively with said openings and sockets are twin series of rotary tumblers 6, having bores corresponding in diameter with the shackle-leg openings and alined therewith for. the reception of the legs of a shackle 7. The tumblers are provided with inwardly-extending locking-tongues 8, which, when alined, are adapted to register with notches or kerfs 9 in the spaced circumferential enlargements 10 on the legs of the shackle, said tongues each being of a length equal to one-half of the length of the tumbler by which it is carried, whereby when the shackle is in its normal or locked position the tongues occupy positions in the transverse planes of the depressions 11 between said circumferential enlargements 10.

The tumblers are provided at their contiguous ends with interlocking or rabbeted joints formed by cylindrical extensions 6, formed on the tumbler at one end to fit in a rabbet formed in the contiguous end of the adjoining tumbler, the terminal tumblers being mounted, respectively, upon a rabbeted collar 11 and in a ring 12. exterior alternately-disposed rabbets 6 and longitudinal grooves or channels 6 to facilitate the independent turning of the tumblers and to insure the accurate alinement of the characters.

The circumferential enlargements 10 on the shackle-legs preferably consist of longitudinally grooved or kerfed sleeves fitted for revoluble adjustment upon the reduced port-ions of the shackle-legs and adapted to be secured at the desired adjustment by means of setscrews 13, terminally engaging circumferential grooves 14 in the shacklelegs.

When it is desired to change the combination, the tumblers are set to the combination necessary to allow the withdrawal of the shackle. The shackle is withdrawn and the set-screws 13 are loosened, after which the shackle is returned to a position in the lock which arranges the kerf 9 in engagement with the plugs 8 of the tumblers. The tumblers are then turned to arrange their peripheral characters to form the desired combinations, and, finally, the shackle is carefully withdrawn and the set-screws tightened to lock the sleeves at the desired adjustment. It will be understood that the turning of the tumblers will also cause the desiredrotary adjustment of the sleeves upon the legs of the shackle.

From the above description it will be seen that each leg of the double or hair-pin shackle is independently locked by a combination of tumblers and both combinations must be Each tumbler is provided with properly set in order to release the shackle, thus adding to the efiiciency of the lock and increasing the difficulty of opening the same without previously knowing the combination to which the tumblers are set.

Various changes in the form, proportion, and the minor details of construction maybe resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having described my invention, what I claim is 1. Alock havinga frame comprising spaced terminal caps connected by side cheeks and provided respectively with shackle-leg openings and a corresponding number of alined sockets, a series of revoluble tumblers permanently mounted in the frame between said caps in alinement, respectively, with the alined shackle-leg openings and sockets, and having their contiguous ends connected'by interlocking joints, and a double or hair-pin shackle having legs adapted to fit axially in the tumblers, and provided with circumferentially kerfed or notched enlargements for engagement by inwardly-extending lockingtongues on the tumblers, substantially as specified.

'2. A lock having a frame or body portion, a series of alined tumblers permanently mount-i ed in the frame, and each provided with an inwardly-extending lug and exterior combination characters, and a shackle having a leg adapted to pass axially into the bores of the tumblers and having notched or kerfed enlargements, said enlargements consisting of sleeves independently mounted for revoluble adjustment upon the shackle-leg, and means for securing each sleeve at the desired adj ustment, substantially as specified.

3. A lock having a frame or body portion, a series of alined tumblers permanently mounted in the frame, and each provided with an inwardly-extending lug and exterior combination characters, and a shackle having a leg adapted to pass axially into the bores of the tumblers, and having notched or. kerfed enlargements for engagement by the lugs of the tumblers,said enlargements consisting of split sleeves revolubly mounted upon the shackleleg, and independent set-screws for locking said sleeves at the desired rotary adjustment,

substantially as specified.

4. A lock having a frame or body portion, a series of alined tumblers permanently mounted in the frame, and each provided with an inwardly-extending lug and exterior combination characters, and a shackle having a leg adapted to pass axially into the bores of the tumblers, and having notched or kerfed enlargements for engagement by the lugs in the bores of the tumblers, said enlargements consisting of split sleeves mounted for revoluble adjustment upon the shackle-leg, and inde- .pendent set-screws threaded in the sleeves for having exterior combination characters, a

shackle having aleg extending axiallythrough the bores of the tumblers, interlocking means carried respectively by the shackle-leg and tumblers, the means which are carried by the shackle-leg being spaced apart to suit the interval between the tumblers and being mounted for independent. rotary adjustment upon the shackle-leg, and locking devices for securing said shackle-carried members of the interlocking means at the desired adjustment, substantially as. specified.

In testimony that I claim the foregoing as my own I .havehereto affixed my signature .in the presence of two witnesses.

HENRY A. REDMAN.
