LOCK.

' Specification of Letters Patent.

Patented Apr. 20, 1915.

Application filed. December 26, 1914. Serial No. 879,084.

To all whom it may concern Be it knownthat I, CHAnLEs G. TAYLOR, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Locks, of which the following is a specification.

This invention relates to improvements in looks, and it is an object of the invention to provide a simple inexpensive lock which is provided with an interior locking means adapted to be shifted by certain movements for locking and unlocking the shackle portions of the look.

It is also an object of the invention to pro vide a lock with cooperating shackle portions and an interior shifting tumbler adapted to be moved in accordance with the position of the lock for controlling the 'action of said shackle portions. 7

It is a further object of the invention to provide a lock with shackle controlling members in which a gravity actuated member within the lock structure is employed to lock and unlock the shackle portion of the device.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawing: Figure 1 is a side elevation of alock constructed in the shackle portions in locked position' Fig. 5 is a side elevation of one of the shackle members with its controlling mem-' ber or disk. Fig. 6 is a similar view of the other shackle member.

It is a purpose of the present invention to provide a lock, usually of the padlock type which is a keyless lock and has separable shackle portions adapted to be brought together to form a complete shackle, the members or disks which carry the shackle member being controlled by a tumbler or disk which may be shifted for looking or unlocking the said shackle portions without the use of a key.

The details and features of the invention will now be more specifically described with reference to the accompanying drawing in which- 1 and 2 indicate cooperating shackle members, 3 and 4 disks carrying the same and 5 a tumbler or shifting member 'for locking the shackle members.

The members 3 and 4 are preferably flat disks or circular members adapted to be applied upon each other, though of course they may be made in other shapes if desired without departing from the spirit of the invention. The members 3 and 4 are pivotally connected at the center by a rivet or pivot bolt 6, so that they may turn upon each other. The shackle portions 1 and 2 usually project from the edges of the said members 3 and 4 and are generally offset at 7 and 8 so that the greater portion of the said shacklemembers will lie in the same plane as will be clearly understood by reference to Fig. 3.

The ends of the shackle members 1 and 2 are preferably made with portions which lap upon and pass each other sufiiciently to forma strong completed shackle when the said members are brought together. The said ends are usually bifurcated at 9 and 10 and one portion turned in one direction and the other portion in the other direction to form a firm joint between the shackle members. The portion '11 is bent parallel with the portion 12 upon the opposite shackle member so that they may lap in parallel position upon each other as shown in Fig. 3.

The other portions 13 and 14 of the bifur cated shackle ends lap upon each other in the other direction and thus extend diagonally across the portions 11 and 12 as shown in said Fig. 3. The shackle portions cannot be sprung in either direction with respect to each other when formed in this way and afford a strongand complete shackle for the lock when in closed position.

In order to lock the shackle members the disks. or members 3 and 4 are provided with openings or slots 15 and 16 which preferably extend radially with respect to the pivot 6 and which coincide or fit one over the other when the shackle members are closed, so that a tumbler member or disk 5, which is made of thicker material than the members 3 and l, may extend into both of the openings 15 and 16 and when occupying the lower portions thereof as shown in F gs.- 1 and t, will lock the said members place.

3 and 4 against movement upon the pivot pin 6. In order to be able to move the members 3 and 4 when it is desired to open the shackle members 1 and 2, the openings or recesses 15 and 16 are provided with offset extensions 17 and 18 at their inner ends, but extending in opposite directions with respect to each other. It will thus be evident that when the tumbler 5 is brought to the inner ends of the openings or recesses 15 and 16, the members?) and 4 may be turned upon their pivot to the extent permitted by the length of the offset recesses 17 and 18.

In using the look when the shackle members 1 and. 2 are brought together and the said lock is held so that the tumbler 5 will drop into the lower portion of the recess formed by the superposed openings 15 and 16, the members 3 and 4 will be locked and the shackle members 1 and 2 will be firmly held in their closed positions. When it is desired to open them, the lock must be turned into a'suiiiciently inverted position to permit the tumbler 5 to roll or drop to the inner ends of the openings 15 and 16, when as indicated in Fig. 2, the membersB and 4 may be moved on the pivot 6 as the tumbler 5 will engage the offset recesses 17 and 18-. The shackle members 1 and 2 may of course be pushed together when it is dedrop again so as to lock the said shackle members. The openings or recesses in the members 3 and 4 must of course be closed to properly hold the tumbler 5, movably in The said recesses need not of course extend entirely through the material ofthe members 3 and 4 as will be evident, but side or check plates" 19 and 20 are preferably used and applied upon the outer faces of the members 3 and 4 to provide walls for inclosing the said recesses 15 and 16 and their offset extensions 17 and 18. The said side enough to be used in the place of any ordi nary padlock. It is quickly and easily locked and unlocked and requires no key or member separate therefrom for accomplishing the locking and unlocking operation. The device may-also be employed as a nov- Copies of this patent may be obtained for The said plates may be shackle members.

elty or puzzle, there being nothing upon the exterior of the lock to indicate in any way, how the shackle-members are to be released and permitted to open. Thus only "those who learn the secret of the lock'can operate it and unlock the shackle. V

' What is claimed is: 1. A look having separable shackle mem bers and a gravity actuated tumbler adapted to be shifted by altering; the position of r dence, a tumbler disk movable in said recesses for locking the disks. against movement, the said recesses having offset extensions for receiving the tumbler when the partsare in unlocked position, and shackle members carried by'said disks.

3. A look comprising .shackle carrying members mounted to revolve with respect to each other and having shackle armsprojecting therefrom, the said arms having interlocking edge portions adapted to form a firm joint between the parts, the said mem-l bers having angular recesses adapted to be brought into coincidence and a disk of sufficient thickness to extend into both recesses for lockingthe shackle arms.

4. A look having a separableshackle, pivoted disks carryingthe members of said shackle and having superposed recesses "formed therein, said recesses havinglateral extensions pro ect1ng 1n opposlte directions with respect to each other from the inner erdsof said recesses, andg'ai loose tumbler end of the said recesses the shackle memberswill be locked, and when the lockiis inverted and the tumbler permitted to fall into the other ends of the recesses, the

shackles will be permitted to open.

5. A look having disks pivoted with re spect to each other and shackle members projecting therefrom,the ends of said members having split portions bent in opposite directionsfor forminga firm joint at the ends of the'said shackle members and means for preventing the'movement of the said disks on their pivot points to prevent the unauthorized opening of the 7 said .100 engaging said recesses, the structure being such that when the tumbler 1s at 'the outer;
