of Huntington, county of Huntington, end

State of Indiana, have invented a certain new and useful Lock forAutomobiles and the Like; and I do hereby declare that'the following is a full, clear, and exact descri tion thereof, reference being had to tl ie accompanying drawings, in \vhichlik'e nil-- rnerals refer to like parts.

The object otthis invention is to rovide a practical and effective means for coking automobiles and the like, so that they cannot be driveneway by any one who cannot release the lock; and especially for locking the steering apparatus thereof so that the lock will be accessible to the chauffeur and so that the belt. of the lock may be locked by him in both the unlocking and locking positions.

. The feature of this look consists in means for locking the bolt in both the locking and unlocking positions thereof. To that end. I provide in a suitable casing or stationary frame a key shalt having a diameter at least twice thevridth of .the key and pro vided with a set of holes or recesses carrying what is here called a middle set of tumblers or pins. in the stationary frame or casing there are two oppositely located series of tumblers or pins, one diametrically oneach side of the key shaft, and spring-pressed so that they will be adapted to enter the holes or recesses in the key shaft when the latter is turned in proper position and the is removed therefrom. v inserted in the key shalt, the middle set of tumblers carried by the key shall; hold the other tumblers out ol the path of movement of the key shaft, whereby it can be given rotary movement.

By reason of the foregoin "construhtion, when the key shai t is given a half revolution and the key is removed, the bolt will be locked and held locked by a set of tumblers, and when the kc shal t is turned another half revolution and the key' ren'ioved, the bolt will be locked in the unlocking YOSitiOn and held so by the other set of turn )lers.

Another feature of theinv'ention consists in mounting the bolt on a sliding frame hav ing a central opening into which the key she-ft rojects and which opening is larger than t 0 key shaft and the key shaft carries an eccentric operating in said opening for Fig. 1.

But when the key is- Inoving said frame and bolt and holding it in the position to which the same may be moved.

Another feature of the invention consists in providing said bolt frame with catches adapted to engage catches on the removable front plate so that when the bolt is in the locking ositioin, ssifl front plate cannot be.- reinove even if the screws extending through it are taken out, for it is locked to the bolt frame and the bolt frame is held place by the bolt and the eccentric.

The general nature of my invention will b understood from the accompanying drawings andthe following description and claims. Figurel is aside clove ion of the upper nart of the steering apparatus of an automobile, the lower portion being broken anvey. Fi 2 is a horizontal section on. the line 2-2 of Fig. 3 is a rear elcvsti n'oi' parts on the line 33 ci'lB-ig. 1, the k being in section and parts broken away. Fig. 4 is a" vertical section on the line e,4. of Fig. Fig. 5 is a section on the l 0 51-5 of Fig. 2. F'g. 6 is the same as Fig. with the key in.- serted, showing the center tumblers moved upwardly by the key to the pe iphery of the key shaft. Fig. '7 is the seine alter t e key has'had a half turn.- Fig. 8 is the same as Fig. 7 with the key removed and the p arts in position 'when the steering gear is locked. Fig. 9 is a front elevation of the lock with the front piste removed and. the tube and steering shaft shown. in vertical section, the bolt being in unlocking position. Fig. 1b is the SGJHO with the ooh in locking position. 'Fig. 11 is a horizontal section on the line 11-11 of Fig. 9, showing the parts in, unlocking n n. Fig; 12 shows the same "parts in looring position.

In the drawings there is shown Steering wheel 20 on the steering shaft 21 whichis tubular and is mounted Witlfifl the stationary r construction is as follows: The

L? sons to carry casing 23 has a chamber for the reciproca Fig. 9. -'lhe chamber 30 isclosed by the front plate 32 and it has extending inwardly from it catches 33 adapted to engage corresponding catches 34 from the bolt frame 31, when the bolt is operated and the parts looked, as shown in Fig. 12. The bolt frame 31 has a rectangular central opening in which the eccentric 0 crates, said eccentric being secured. on the ey shaft 41, which has a slot.

as for the key 43. When the device is unlocked, the frame 31 is withdrawn by 'a half rotation of the key and key shaft and eccentrio 40, as shown in Fig. 9. When the key is turned a half rotation the key shaft and eccentric 40 force the bolt into looking ongagement. In either looking or unlocking position, therefore, the bolt and bolt frame are firmly held in place by the eccentric 40.

its shown in Figs. 4: to 8, there are three sets of tumblers, the upper set of tumblers being mounted in the frame 23 and consist ing of pins or plates pressed downwardly by spiral springs 51, said s )rings being accessible by the removable top p ate 52;, There is also a lower set of tumblers 53 in said casing 23 and corresponding with the tumblers 50 but forced upwardly by the sprin s 54. Both sets of

tumblers

50 and 53 are ins normally pushed toward the key shaft 41. Said key shaft is provided with a ccntralset of tumblers 55 in suitable recesses or holes extending through the portion thereof 0 posite the key slot, shown in Fig. 4. no tumblers 55 and the holes in which they are mounted are adapted to register with the other tumblers 5t) and Before the key is inserted the tumblers are in the position shown in Fig. 4, the upper set of tumblers projecting into the recesses in the key shaft and thus locking it so as to hold the lock bolt 27 inthe unlocked position shown in Fig. 9. When the key is inserted as shown in Fig. 6, it forces the middle set, of tumblers 55 upwardly to the upper periphery of tho key shaft, whereby the key can be given a half rotation and bring the parts in the position shown in Fig. 7, which will cause the bolt to lock as shown in Fig."

16). In the position shown in Fig. 7, the upper set of tumblersare still held in their u )per positions by the periphery of the key laft, while the lower set of tumblers are held in their lower risengagingpositions by the middle fof tumblers, which are in this "hrs-canoe pressed downwardly. When the key" iii-removed fror'ii ,the position shown in jtlieilower' set of tumblers will be spring-pushed upwardly into the position shown 1n Fig. 8, and therefore, into locking engagement withv the key shaft, and thus the bolt 27 will be heldin its locking position.

When the bolt is in the locking position, as in Fig. 10, it is impossible to remove the front plate 32 even if the screws be taken out for it is in looking engagement with the bolt frame 31 which is held from backward movement by the bolt and the eccentric, and tho the plate 32 is held from the opposite movement by the shoulder 57.

What I claim' as my invention and desire to secure by Letters Patent is:

1. A look including a key shaft provided with a recess on one side thereof, oppositely located s ring-actuated tumblers adapted successive y to engage the recess in the key shaft as it given a semi-rotary movement, an eccentric on the key shaft, a sliding frame movable and hold by said eccentric, and a bolt connected with said frame.

2; A look including a casing, akey shaft mounted therein with a recess on one side, oppositely located spring-actuated tumblers adapted to engage said recess when the key shaft is given a semi-rotary movement, an eccentric on the key shaft, a bolt frame actuated and hold by said eccentric and having on its outer face suitablecatches, a bolt secured to said frame and extending through a part ofthe casing, a removable front plate provided with inwardly extending catches adapted'to engage the catches on the bolt frame when the bolt is moved to the locking position, and a shouldcronthe casing to no vent the releasing movement of said plate whereby said plate cannot be moved while the bolt is in the locking position, substantially as set forth.

3. A look including a casing, a key shaft therein provided with a longitudinal key slot and a radially extending recess from the eriphery into said key slot, oppositely ocated spring-actuated tumblers mounted. in the casing and adapted successively to enter said recess at each semi-rotary movement of the key shaft, a tumbler in the recess in the key shaft that is actuated and cont-rolled by the insertion or removal of the key, a bolt, and means actuated by the key shaft for moving and holding the bolt.
