PERMUTATION PADLOGK.
APPLIGATION FILED MAY 21, 1908.
Patented Nov. 10, 1908.
L @hmmag JAMES A. COWIE, OF CHESAW, WASHINGTON.
PERMUTATION-PADLOCK.
No. 903,680. Specification of Application filed May 21,
To all whom it may concern:
Be it known that I, JAMES A. CoWIE, 1- citizen of the United States, residing at Chesavv, in the county of Okanogan and State of lVasliington, have invented certain new and useful Improvements in Permuta-A tion-Padlocks, of Which the following is a specification, reference being had to the accompanying drawings.
My invention relates to improvements in permutation padlocks and consists of the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed.
One object of the invention is to improve and simplify the construction and operation of devices of this character and thereby render the saine less expensive and more durable.
A further object of the invention is to provide a device of this character by means of Which the combination of the lock may be readily changed Without altering` the construction of any of its parts.
The above and other objects of the invention are attained in its preferred embodiment illustrated in the accompanying dravvings, in Which Figure 1 is a side elevation of my improved permutation padlock; Fig. 2 is an enlarged sectional vievv through the lock; Fig. 3 is a transverse section taken on the plane indicated by the line 3 3 in Fig. 2; Figs, 4 and 5 are detail views of one of the tumblers; and Fig. 6 is a detail vieW of one of the tumbler rings.
My improved padlock comprises tvvo substantially U-shaped sections 1, 2 which form the shackle and Which are pivotally connected at one end, as at 8. The free end of the section 1 is formed with a reduced shaft 4 the outer end of Which is externally screw threaded, as at 5, and at the inner end of Which is an annular flange 6 forming a stop shoulder. The shaft 4 is also formed With a longitudinal groove or channel 7 to receive the shank or tongue 8 Which is carried by the free end of the section 2 and is in the form of a lat plate having its outer edge formed With a series of notches 9.
Arranged for rotation upon the shaft 4 is a series of tumblers 10 which are retained in position by a nut 11 engaged with the threaded end of the shaft and having a groove or channel 12 to register With the groove 7 in the shaft When said nut is screwed up upon the latter. Each of the Letters Patent. Patented Nov. 107 1908.
1908. Serial No. 434,154.
tumblers is in the form of a circular disk or plate having a central bore or opening'l to receive the shaft and a groove or recess 14 which corresponds in Width to the thickness of the tongue or shank S and which is adapted to be brought into register With the groove 7 in the shaft to permit said tongue or shank 8 to be inserted in and Withdrawn from said groove 7 to close and open the lock. In one face of each of the tumblers is formed a circular recess or cavity 15 which is concentric With the bore 13 and which is adapted to receive a spring 1G for holding the tumbler under tension and preventing it from being casually rotated. Each of the springs 16 is in the form of a curved or substantially semi-circular shaped piece of resilient Wire having one of its ends 17 bent at right angles and inserted in a radial socket 18 formed in the shaft 4 and its curved free end bearing against the Wall of the recess or cavity 15, as clearly shown in Figs. 2 and 3 of the drawings. By constructing the tumblers and springs in this manner and arranging the latter as set forth, it will be seen that the parts of the device may be produced and assembled at a small cost and will be exceedingly strong and durable.
The numbers, letters or other symbols Which form the combination of the lock may be suitably placed upon the outer edges of the tumblers, but in order to permit the combination to be conveniently changed Without altering the construction of the lock, I place such combination symbols 19 around the outer surface of annular bands or rings 20 which are removably and rotatably secured to the tumblers. Said rings 20 are adapted to tit the tumblers and the latter are formed adjacent to one side With annular radially projecting flanges 21 which serve as stop shoulders for` said rings. The rings may be rotated upon the tumblers to bring any combination symbol 19 opposite the groove 14 in the bore 13 of the tumbler and it may be then secured in such position by means of a small set screvv 22 arranged in a threaded opening in the ring and having its inner end pointed to impinge against the outer surface of the tumbler, as clearly shovvn in Figs. 2 and 5. It Will be seen that by means of this construction the combination of the lock may be quickly and easily changed by removing the nut 11 and the tumblers and then shifting the rings or outer sections 20 of the tumblers upon their inner sections or body portions, and then replacing the tumblers and the nut.
In operation, it will be seen that when the tumblers are so turned that their grooves 14; register with the groove 7 in the shaft, the shank or tongue S may be inserted in or removed froni said registering grooves to close er open the lock; and that When said tongue is inserted in said grooves, and its notches 9 register with the grooves let in the tumblers, the latter may be turned so that they enter the grooves 9 and lock the ,two sections l, 2 of the shackle together. A suitable arrow or mark may be provided upon the flange G and with which the proper combination symbols upon the rings 2O must be brought into transverse alinement in order to have the grooves lll register with the groove 7.
Having thus described my invention what I claim is:
l. A permutation padlock comprising tWo substantially U-shaped sections pivotally united at one end, one section having its free end formed with a shaft and a shoulder at the inner end of said shaft, the latter being formed with a longitudinal groove and With a series of seats or sockets, tumblers rotatably mounted upon the shaft and formed in their bores with grooves to register with the one in the shaft, one face of each of said tumblers being formed with a concentric cavity, curved springs arranged in said cavities of the tumblers and having angular ends inserted in the seats or sockets in the shaft and their free ends bearing against the Walls of said cavities to hold the tuinblers under tension, means for retaining the tumblers upon the shaft and a tongue or shank upon the free end of the other section and formed With notches to receive the tuinblers when said tongue or shank is inserted in the registering grooves in the shaft and tumblers, substantially as described.
2. A permutation padlock comprising pivotally united sections, one section having its free end provided With a grooved shaft and the other section With a notched tongue to enter the groove in said shaft, rotatable tumblers upon said shaft, each tumbler being in the forni of a circular plate or disk having its bore formed With a groove to register with the groove in the shaft and its outer surface formed upon one side with a radially projecting annular ange, rings carrying combination symbols rotatably mounted on said tumblers and engaged with said iianges and formed With threaded apertures, and set screws arranged in the threaded apertures of said rings and adapted to iinpinge against the tumblers to hold the rings in adjusted positions.
In testimony whereof I hereunto afiix my signature in the presence of two Witnesses.
