'To all whom it may concern:
mutation locks, and has for its object toprovide a lock'of the character specified and the like, wherein a boltis provided an a casing in which the bolt is mounted and adapted to be arranged on a fixed support adjacent to the wheel, the bolt having a shoe for engaging the wheel to lock the same, and wherein interlocking mechanism is provided in connection with the bolt and the casing, for holding the bolt in locked position: i
A further object isto provide a lock of the character specified adapted for use in any connection as al'ongitudinally movable bolt having locking means, as specified.
In the drawings:
Figure 1" isa side View of the improved lock, in locked position;
Fig. 2 is a front view in unlocked position' 3 is a section on the line 3-3 of Fig. 2, looking inthe direction of the arrows adjacent to the line;
Fig. 4: 1s a section on the line 4-4 of 23, looking in the direction of the arnff iwsadjacent to the line;
Fig. ,5 is a perspective view of the bolt, and
Fig. 6 is a similar viewof one of the tumblers. a
The present embodiment of the inven- -tion is shown in connection with a flywheel l of a motor 2, the fly wheel havin a series of peripherally arranged teeth 3 with which the lock coo crates. The lock comprises a bolt 4 of suitable length and cross section,
having at one end a head 5 and provided at the other with a shoe 6 having teeth for engaging the teeth 3. This shoe is shown as provided with a socket or recess for receiving the end of the bolt, and a set screw 7 isthrea-ded through the shoe into engage- -ment with an opening in the bolt to hold the parts in position. i The bolt is mounted to move longitudipally in a casing 8 which has a bore 9 for receiving the bolt. The bore extends entirely through the casing, and the casing is provided with a reamed-out or enlarged portion 10, the said portion opening at opposits sides and atthe front of the casing,
and being designed to receive the rotatable tumblers to be described. At the rear the casing has a lug '11 which is adapted to 'receive a clip or staple 12 on the motor 2.
A series of ring-shaped tumblers 13 is arranged within the recess or counterbored portion 10, 111 superposed relation, and with the bolt passing through the central opening of the tumblers. Each of these tumblers is provided on its peripheral surface with a series of symbols 14, letters in this instance.
Each of the tumblers 13 is provided on its inner surface with an inwardly extending lug 15, and these lugs are adapted to move in annular grooves 16 in the bolt and in a longitudinally extending groove 17 which intersects all of the annular grooves and extends to the end of the bolt provided with the shoe. The grooves 16 are spaced apart and fit and receive the lugs 15 when the tumblers are in superposed position, and it will be obvious that while the tumblers are in the annular grooves, the bolt cannot move longitudinally until all of the lugs 15 are in register with the longitudinal groove 17.
When this occurs, the bolt may be moved longitudinally into the position shown in' Figs. 1 and 3.
In use, when it is desired to lock the wheel with the parts in the position of Figs. 2
and 3, the tumblers are -rotated until all of the lugs 15 are in register with the groove 17. Blhe bolt may now be moved toward the wheel to cause the teeth of the shoe 6 to engage with the teeth 3 of the wheel. When now the tumblers 13 are-turnedto bring the lugs 15 out of register with the groove 17, and into the grooves 16; it will be obvious that the bolt will be locked against ion itudinal movement until the lugs are again rought into register with the longitudinal groove.
In order to permit the tumblers to be brought into a predetermined position, that is, with the lugs 15 in register, the letters on the periphery of each tumbler are arranged in a certain predetermined manner with respect to the lug, so that when a'certain predetermined arrangement of letters is brought into register with one edge of the opening 10 or with an indicator on the casing, the said lugs will be brought into register with the groove 17 .i For instance, the arrangement might be such that, when the lugs were in register with the groove 17, a certain word might be spelled by the letters with the tumblers at a predetermined point.
It will be obvious that without the shoe the lockmight be used as an ordinary bolt engaging a hasp on the door or an opening in the door, or in any other connection where a longitudinally movable bolt is desired.
lVhen the bolt is used for a door, for in-- stance, the innermost annular groove forms a guide for the proper placing of the bolt since the lug and the innermost tumbler cannot move beyond the "groove. The casing is )rovi .led with an inwardly extending lug 18 which moves in the groove 17 to prevent rotation of the bolt. 7
It will be observed that the bolt is rotatable in the casing and with respect to the tumblers, in either the position of Fig. 1 or that of Fig. 3, that is when the bolt is in locking position oe in unlocking position. Thus to prevent unauthorized locking of the bolt when it is desired that the bolt remain unlocked, it may be given a halt turn from the position shown in Figs. 1 and Q, and
before the bolt can be locked, itmust be returned to original position.
I claim A permutation lock comprising a casing having a bore enlarged at one end to form a tumbler receiving chamber opening at the front of the casing, a bolt slidable and rotatable in the bore, a series of ring-shaped tumblers in the enlargement and encircling the bolt each tumbler having an inwardly extending adial lag, the bolt having an annular groove for each tumbler and an additional annular groove, said grooves being spaced to correspond with the spacing of the lugs ot the tumblers and adapted tor engagement by said lugs to hold the bolt in locking or unlocking positioin and a 1011- gitudinall v extending groove intersecting the annular groove stopping short at the innermost of the grooves to provide a limiting means for the ()Hh 'ard movement of the bolt by the engagementof the lag of the innermost tumbler with the inner wall oi the innern'iost groove.
