SAFETY-LOCK- To all whom it may concern: 5

Be it known that we, PIERRE L'IEVENS, a

subject of the Belgian King, and GUILLAUME JAHN, a subject of the German Emperor, residingat Brussels, Belgium, have invented new and useful Improvements in Safety- Locks; and we do hereby declare the following to be a full, clear, and exact description of the same.

nation-locks for V&l1SBS,'bOX6S, trunks, and the like, and has for its object the provision of a lock of this character wherein the locking mechanism is opened by a prescribed movement of a plurality of combination members wherein the lock may be retained in an open position by said members, and, further, wherein the parts may be so adjusted as to permit the owner of the valise or trunk to readilychange the combination.

The invention will be more particularly described in connection with the accompanying drawings and will be more fully ascertained "of Fig. 3.

' 5 of Fig. 3. Fig. 6 is a similar View showing the parts in a different position. Fig. 7 is a detail bottom view of one of the combination members, taken on line 7 7 of Fig. 8. Fig. 8 is a side elevation of oneof the combination members and the locking-nut therefor. Fig 9 is a lan view of one of the locking-disks embodied in the operative structure. Figs. 10 and 11 are detail plan views, respectively, of operative parts of the lock.

Like characters of reference designate similar parts throughout the different figures of the drawings. I

As shown, the invention comprises the lock proper, which is indicated as a whole by A and is mounted upon the frame A of the valise, and the lock-engaging member, which is indicated by B and is mounted upon the frame B.

Referring to the structure of the body of the'lock, the same comprises a stationary casing 1, whose top wall is slotted at 2 and provided with looking projections 3, which form one of the elements of the lock proper Specification of Letters Patent. Application filed July 29,1905. Serial No. 271,833.

I one direction. This invention relates to lmproved combi- Patented Oct. 30, 1906.

and will hereinafter be referred to as the stationary plate.

4 designates a disk-plate mounted upon the stationary plate 1 and provided with slots 5, terminating in enlargements 6. The slots 5 are adapted to fit over and operatively engage the projections 3, which latter limit the movement of the disk-plate 4' in It will also be obvious that the slots of the

plates

1 and 4 are approximately of the same when in the position shown in Fig. 3. A plurality of locking-disks 8, equal in number to the slots provided in plates 1 and'4, are mounted upon the latter and are provided with cylindrical shanks 7, which project through the enlargement 6 of plate 4 and also *through slots 2 of plate 1, the contracted slots 5 of plate 4 retaining-said shanks and disks in prescribed relation with the plate 4, but permitting rotary motion of the disk.

length and that they are adapted to register Said locking-disks are provided with lockin recesses 9, which preferably diverge from their bases outwardly, the base portions of said recesses being equal in width to the projections 3 and adapted to cooperate therewith in certain adjustments. One of said disks 8, preferably the center one, is provided with a concentric slot 22, registering with the base portion of its recess 9.

A plurality of combination members 'in the form of centrally-recessed knobs14 are provided, adapted to ijnclose the disks8 and the projections 3 and to extend downwardly toward the plate 4. Said combination members are provided on their upper faces 'with a plurality of numerals or Symbols or like designating-marks and with depending shanks 13 of poly onal cross-section, being reduced cylindrica 1y at 13 and having a further threaded reduction at 15, adapted to be engaged by nuts 16; The shanks7 of the disks 8 are hollow and are complemental in formation with the shanks 13 to provide nonrotative engagement between the 'lo'c'king members l4'and the disks 8. The which is indicated as a whole by A, is pro--v vided with slots 17*, through which the cyplate 17 lindrical portions 13* project, said slots 17 providing for movement of the shanks 13, looking members 14, and disks 8 in one direction. The nuts 16 enga e the lower face of the plate 17 and hold the ocking members 14,,

and therethrough the disks 8 and plate 4, in

position upon the plate 1. It will 'beobvious.

from the foregoing that the nuts 16 may be removed, thereby permitting disconnection of the locking members 14 from the disks 8 and readjustment of said members with respect to the disks 8 whenever it is desired to change the combination.

Below the plate 1 there is provided a locking-plate 10, through which the hollow shanks 7 project, said plate being yieldingly held in position by a spring 11, resting upon Washers 12, secured to shanks 7. Said locking-plate is provided with locking projections 19', as shown. in Figs. 3 and 4, adapted for en gagement with catches mounted upon a plate 20, constituting the lock-engaging member and secured to frame member B. Said catches project into the casing 1 through slots 21, formed therein, in a manner to be engaged by said projections 19. The locking-plate 10 is normally held in a locking or extreme right position by a spring 18, secured to lugs upon the

plates

10 and 1, respectively.

The operation is as follows: The parts in their normal position, as shown in Fig. 3 and as held'by spring 18, provide for a clearance between the projections 3 and recesses 9 of the disks 8, thereby permitting the latter to be freely turned through the locking members 14. Assuming that the parts are in the osition shown in Fig. 3 and it is desired to ock the valise, the frames A and B are operated together, thereby engaging the catches of plate 20 with projections 19, there being a sufiicient clearance between the projections 3 and the peripheries of the disks 8 to permit rotation of the latter. After the frames A and B" have been secured together, as described, the combination is fixed by turning the locking members 14 to bring the recess 9 out of register with the projections 3, this operation preventing movement of the plate 10 to the left a sufficient distance to disengage the projections 19 with the catches of the plate 20. In order to position the locking members14 in a manner to unlock the valise, it will be necessary to turn the locking members 14 to bring each of them into a registering position with the projections 3, and to do this the combination must be known to the operator. Assuming that the operator desires to unlock the valise, he will rotate the locking members 14 in a manner to bring the recesses 9 into register with the projections 3, and will thereupon move the parts to the left, thereby disengaging the projections 19 from the catches of the plate 20. If it is desired to retain the parts in position to prevent the spring 18 from bringing the projections 19 into engagement with the catches of the plate 20, the parts are moved to the left in the direction of the arrow shown in Fig. 6 until the bases of the recesses 9 are in engagement withthe projections 3, whereupon the central locking member 14 is rotated to engage the central projection 3 with the concentric slot 22, thereby holding the movable parts in an extreme left or unlocking position. If at any time it is desired to change the combination, any one or all of the locking members 14 may be disengaged from the disks 4 by first removin the nut 16 and replaced in a manner to change the relation of the recesses 9 With respect to the combination members upon the locking members 14.
