LOCK.

Specication of Letters Patent.

Patented Mar. 14, 1911.

Application filed September 2, 1909. Serial No. 515,864.

To all whom 'it may concern.

Be it known that I, LoUIs R. HIBBARD, a citizen ofthe United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented Vnew and useful Improvements in Locks, of which the following is a specification.

This invention relates more specifically to a combination lock of the tumbler disk type, and more especially to that class of locks wherein one member is pivotally mounted on an immovable structure, and adapted to coperate with a stationary member mounted on a movable structure when in a locked condition, and a main object thereof is to provide a combination lock of the swinging type .that may be effectively employed in a variety of situations where keylocks have heretofore been employed thus dispensing with the use of keys.

Another and important object is to provide a novel form of lock of the two part swinging type in which the locking mechanism secured to the movable member will be maintained in an operative position during its disengagement from the lock engaging, or stationary member, thus permitting an instant engagement of the two members without necessitating the manipulation of the combination of the locking mechanism.

Another object is to provide a locking mechanism in which a change of an existing combination can be effected without the use of tools or dismantling the locking mechanism.

A further obj ect is to provide a lock which is simple in construction, reliable in operation, which is composed of few parts, and which will fulfil in a satisfactory and eilicient manner the conditions imposed upon it.

I accomplish the above objects by means of the device described herein and illustrated in the accompanying drawings in which F igure lis a rear elevation of the movable member of the lock. Fig. 2- is a cross section through the stationary member of the lock. Fig. 3- is a longitudinal section through the movable member, taken on line 3--3 of Fig. 1. Fig. 4:- is a side elevation of the two locking members in a locked relation to each other, parts being in 'section for clearness of illustration. Fig. 5- is a front elevation of the upper portion of the movable member, showing the indicating dial.

In a practical embodiment of my invention I have illustrated it as adapted for use as a trunk lock, but it may be employed in various other situations, such as maintaining a rotary member in a locked relation to a stationary member, and when used in this situation the locking mechanism is held in a stationary position and the stationary member in a removable position, in both `situations the operation of the locking mechanism is essentially the same.

Referring more particularly to the drawings 10 designates a bearing which is rigidly secured to a support 11, in this case the body of a traveling trunk, by rivets 12. Pivotally mounted in bearinglO is a movable lock member 13, which preferably consists of an elongated metallic hasp or shank ltcarrying on its inner face and at the top thereof a cylindrical head 15 in which is mounted a locking mechanism. The inner face of this cylinder is provided with a circular recess 16, and a centrally disposed bore 17 that opens therethrough for the reception of a spindle 18, that carries a portion of the tumbler mechanism on its inner end, and an indicating dial 19 on its outer end, the dial beingrigidly secured thereto and rotating therewith. The outer end of the spindle is provided with a knurled operating head 20 and the inner end is headed, the inner face of the head bearing against a face plate 21, which is secured by rivets or other securing means to the face of the cylindrical head 15. Plate 21 is provided near its periphery with an aperture 22, that registers with a cylindrical recess 23 formed in head 15, and whose diameter is the same as the aperture in the face plate. Mounted in this recess is a spring controlled bolt 24 the operation of which will be more particularly described farther on.

That portion of the tumbler mechanism which is carried by the spindle 18, and which has been referred to hereinbefore, consists of anapertured tumbler disk, 26,and an operating collar 27, held in frictional engagement therewith. Disk 26 is provided in its outer edge with a notch 28 of a segmental configuration, and it bears against 'the bottom of the cylindrical recess, itsperiphery being out of contact with the walls of the recess 23. Operating collar 27 is of smaller diameter than disk 26 and carries on its periphery an engaging lug 29. Interposed be- 'tween collar 27 and the faceplate 21, and

tumbler disk is then changed, the change being effected in subsantially the same manner as the first disk 30, with the exception that instead of rotating a collar to operate the disk, the spindle only is operated being rotated in a direction the reverse of its first rotation, the disk being held stationary by the bolt 34. When the new number, which has been selected is reached, for illustration l0, on the dial, it will be obvious that when unlocking member' 13 from its socket, that when the number 10 reaches the indicating point 50, that the notch 28 on this disk will be brought into a proper registering position with the Stud 43 and permit a disengagement therefrom.

If more than a two number combination is desired the number of tumbler disks may be increased, the operation of unlocking and resetting a combination being essentially the same in every particular, as for the above described construction. I

From the foregoing description it will be apparent that I have provided a simple and efficient combination lock that will admirably subserve the conditions for which it is designed.

What I claim is 1. A ycombination lock comprising a movable case, a plurality of tumblers mounted in said case, means for setting said tumblers according to a combination to lock and unlock, a spring pressed member coperating with said tumblers and movably mounted in said case normally locking said tumblers against rotation when said lock is open and a iiXed member removed from said case adapted to displace said iirst member when the lock is being closed to release said tumblers.

2. A combination lock comprising a case, a plurality of tumblers mounted therein adapted to be set to a combination, a keeper cooperating with said tumblers when the lock is locked and a movable bolt normally engaging said tumblers when the lock is unlocked and normally holding said tumblers in alinement, said keeper affording means for displacing said bolt when said lock is closed, whereby said tumblers are released.

3. A combination lock comprising a case, a plurality of tumblers movably mounted therein and adapted to be set to a combination, said case having a bore, a spring pressed bolt miivably mounted in said bore and nor-y mally engaging said tumblers to lock the same against rotation when said lock is open, and a keeper adapted to engage said bolt and displace the same when the lock is closed thereby releasing said tumblers, said keeper being adapted to vcooperate with said tumblers to hold the lock in a locked condition.

4. A combination lock, comprising a casing, a tumbler mechanism mounted therein including tumblers and means to operate the same from the exterior, in combination with a keeper cooperating with said tumblers to lock the lock and a member movably mounted in said casing and movable With respect to said keeper engaging both of said tumblers to prevent a movement ot the tumbler mechanism when disengaged from said keeper.

5. A combination lock comprising a stationary lock engaging member provided with a keeper, a movable lock member, tumblers mounted thereon, means for alining said tumblers to disengage the same from said keeper, and a spring pressed member adapted to be displaced by said keeper and normally engaging said tumblers when the lock is open to maintain the alinement of said tumblers.

In witness that I claim the foregoing I have hereunto subscribed my name this 28th day of August, 1909.
