PERM UTATlON-PADLOCK.
SPECIFICATION forming part. of Letters Patent No. 707,676, dated August 26, 1902.
Application filed May 18,1902. $erialNo.107,070. (No model.)
To all whom it may concern:
Be it known that 1, DAVID R. COUGHLEN, a
citizen of the United States, residing at (Joncordia, in the county of Cloud and State of Kansas, have invented a new and useful Permutation-Padlock; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The invention relates to a permutation-padlock; and it has for its object to provide a simple and inexpensive padlock of this character capable of a large variety of combinations and adapted to enable the combination to be quickly changed without varying the relative position of the tumblers.
A further object of the inventionis to provide a permutation-padlock in which the rotary tumblers Will be positioned in such a manner as to enable them to be readily manipulated for opening the lock.
The invention consists in the novelarrange ment and construction of parts hereinafter described and shown,and particularly pointed out in the claims hereto appended.
In the drawings forming part of this specification, and in which like numerals of reference designate corresponding parts, Figure 1 is a side elevation of a permutation-padlock constructed in accordance with this invention. Fig. 2 is a longitudinal sectional view of the same. tioual view of the same. Fig. a is a detailed view of the setting-ring for changing the combination. Fig. 5 is a detailed View of the blank key for holding the tumblers While changing the combination.
Referring to the drawings, 1 designates a shackle composed of two approximately U- shaped sections 2 and 3, connected at one side by a pivot 4, the section 2 being bifurcated at one end to receive the reduced end 5 of the other section or member. The pivot kwhich preferably consists of a rivet, passes through the sides of the bifurcated end of the section or member 2 and through the reduced end 5 of the section or member 3. The other end of the section or member 2 is provided with a round core 6, having alongitudinal groove 7 for the reception of a shackle arm or pin 8, and the latter is provided at its outer edge Fig. 3 is a transverse sec' with a series of transverse notches 9, adapted to be engaged by a series of rotary tumblers which are mounted on the core 6 and which are provided with notches or recesses 10, adapted to be brought into register with one another and with the groove 7 to permit the shackle pin or arm to be placedin and removed from the groove 7 of the core, as will be readily understood. The section or member 2 of the shackle is provided at the inner end of the core with an annular flange 11 to receive a rotary setting-ring 12, having a pointeror indicator 13 and adapted to be rotated on the annular flange to change the position of the indicator with relation to the rotary tumblers whereby the combination of the permutation-padlock is changed. The setting-ring is provided at its inner edge with an in wardlyextending annular flange 14,
forming a reduced opening of the same diameter of the round core and adapted to abut against the inner face of the annular flange 11, whereby the setting-ring is retained in place when the parts are assembled. The
setting-ring is secured in its adjusted position by means of a set-screw 15, mounted in a threaded perforation and arranged to engage the periphery of the annular flange 11 of the shackle. When it is desired to change the combination, the set-screw is loosened and the setting-ring is partially rotated to shift it from one set of characters on the tumblers to another. The tumblers, which may be of any desired number, preferably consist of a pair of innertumblers 16 and 17 of the same diameter and a pair of outer tumblers 18 and 19 of less diameter than the inner tumblers, whereby the'outer edges of the innor tumblers are caused to project beyond the outer tumblers to enable them to be readily grasped for manipulating them. outer tumblers are of slightly greater diameter than the setting-ring and a fixed ring 20, secured to the outerend of the core and retain- The i ing the tumblers and the setting-ring in place I of the tumblers in alinement.
same for locking the pivoted member or section 3 to the other member or section 2. The tumblers are provided at their peripheries with suitable numbers, letters, or other characters, which are adapted to be brought into register for arranging the notches or recesses When it is desired to lock the pivoted member, the shackle arm or pin is placed in the groove of the core and the tumblers are rotated to throw their notches or recesses out of alinement, and the padlock cannot be opened until the said notches or recesses 4 are again brought into register with the groove of the core.
In order to facilitate the manipulation of the lock in changing the combination, a blank key 22 is provided and is placed in the lock to hold the tumblers in register with the groove of the core while the setting-ring is being adjusted. This will enable the new combination to be readily ascertained, as the tumblers cannot possibly slip out of position.
From the foregoing it will be seen that the permutation-padlock is simple, strong, inexpensive, and durable, that the projecting portions of the tumblers enable them to be readily manipulated, and that the combination may be quickly changed by simply adjusting the setting-ring to shift the position of the indicator.
What I claim is v 1. In a lock the combination of a shackle having a movable member provided with notches, a series of rotary tumblers mounted on the shackle and arranged to engage the notches of the movable member, and a rotary setting-ring adjustably mounted on the shackle and provided with an indicator and adapted to shift the same to change the combination, substantially as described.
2. In a lock the combination of a shackle having a movable member provided with notches, a series of rotary tumblers provided with characters, a rotary setting-ring adjustably mounted on the shackle and having an indicator and capable of rotation for shifting the position of the same,and means for clamping the setting-ring in its adjusted position, substantially as described.
3. In a device of the class described, the combination with a permutation-lock having a series of rotary tumblers provided with characters, of a rotary setting-ring adjustably mounted on the shackle and provided with an indicator and capable of rotation to shift the position of the indicator to change the combination, and meansfor securing the setting-ring in its adjusted position, substantially as described.
4. In a lock the combination of a shackle having a movable member and provided with a grooved core, said shackle being also provided at the inner end of the core with an annular flange, a flanged setting-ring adjustably mounted on the flange of the core and provided with an indicator, a clamping device for holding the setting-ring in its adjusted position, a series of rotary tumblers mounted on the core and provided with notches or recesses and means for securing the tumblers on the core, substantially as described.
5. In a lock the combination, of a shackle having a grooved core, a series of tumblers mounted on the core and provided with recesses, a rotary, setting device having an indicator and a key for holding the tumblers while the setting device is being adjusted, substantially as described.
6. A lock provided with outer tumblers and having a pair of inner tumblers of greater diameter than the outer tumblers, the latter being of greater diameter than the adjacent fixed portions of the lock to provide projecting edges, substantially as described.
In testimony whereof I have hereto affixed my signature in the presence of two witnesses.
DAVID R. COUGHLEN.
