LOCKING DEVICE FOR AUTOMOBILES.

weaves.

Application filed March 26, 1917.

To all whom it may concern:

Be it known that IRA 'YELTON and RAY- MOND C. SIRY, citizens of the United States, residing at Grants Lick, in the county of Campbell and State of Kentucky, have. in vented certain new and useful Improvements in Locking Devices for Automobiles, of which the following is a specification, refer ence being had to the accompanying drawings.

This invention relates to automobile attachments, and particularly to means for locking automobiles to prevent their being stolen or used, without authority.

The general object of the invention is to provide a very simple, cheaply constructed, and easily applied device for the above stated purpose, which will prevent the steering mechanism from being used while the locking device is in applied position, and a further object in this connection is to provide means for also locking the starting crank.

A further object is to provide a device of this character so constructed that it does not have to be removed from the machine in order to permit the machine to be steered and operated.

Other objects will appear in the course of the following description.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of an automobile locking device constructed in accordance with our invention, the axle and steering rod being shown in section;

Fig. 2 is a top plan view of our device;

Fig. 3 is a longitudinal sectional view thereof;

Fig. 4 is a vertical sectional view thereof, the member 25 and the sector gear 22 being in elevation;

Fig. 5 is a section. on the line 5-5 of Fig. 3.

The device, as illustrated in Fig. 2, consists of a block or a body 10 having a relatively thick head 11 at one end, this head being longitudinally slotted parallel to the face of the body, as at 12, and this slot being of sufiicient width to permit the connecting or steering rod, which connects the steering knuckles, to be inserted in the slot and moved freely therein. The end of the slot 12 is closed by a removable block 13, whose inner face is concavely rounded, as at 14, This block may be held in place in any Specification of Letters Patent.

suitable manner, so that it cannot be readily removed. The opposite end of the body 10 from the head 11 is longitudinally slotted as at 15, and operating in this slot is a rack bar 16, having teeth 17 upon one face. This rack bar constitutes a plunger rod and is angularly bent, as at 18, and extends down ward, and is then again angularly bent to provide a plunger 19, which extends through a passage 20 formed in the front wall of the head 11. It will be understood that the plunger is reciprocable in the opening 20 toward and from the rear wall formed by the block 13. Formed upon the upper face of the body 10, on each side of the slot 15, are the ears 21, and mounted between these ears is a sector-gear 22 having trunnions 23 which pass into the ears 21. These trunnions may be formed by a pin driven through the bearings 23 and through the member 22. This sector gear 22 has an arm 24: extending radially therefrom, this arm at its extremity being formed with a laterally disposed jaw 25 and a portion 26 of an opposed jaw. Pivoted to the portion 26 is a section 27, which completes the jaw opposed to the jaw 25, thisjaw section 27 being formed with a forwardly extending lug 28. This lug 28 and the forward end of the jaw 25 are adapted to lie flat against each other and are formed with transverse perforations 29, for the reception of the hasp of a pad lock 30.

In order to attach the body 10 to the front axle of theautomobile, I provide the downwardly extending stud bolts 81, which may be formed with the body 10 on each side of the slot 15, these stud bolts being screw-threaded at their outer ends for engagement with nuts 82, and mounted upon each pair of stud bolts is a longitudinally extending bar 33 adapted to extend beneath and clamp against the under face of an axle. The under face of the body 10 on each side of the slot is slightly recessed, as at 34:, to provide for engagement with the upper face of the axle.

It will be noted that the arm 25 is formed on its under face with a stop lug 35, which abuts against the end of the rack bar 16 when the rack bar is jammed against the connecting'rod 36 and this takes the strain from the teeth 17 when the rack bar 16 is locked. It will also be noted from Fig. 2 that the ears 21 are cut away as at 37 in order to allow the arm 24; to lie flat on the upper faceof the body 10 whenshifted rearward.

In the practical use of this invention, the block 13 is removed and the. connecting rod 36, connecting the steering knuckles of the automobile, is disposed within the slot 12. The block 13 is then replaced and engaged with the body 10. When it is desired to lock the machine, the arm 24: is rotated toward the front of the machine in a position to engage with the starting crank 37. This rotation of the arm 24: causes the rack 16 and the plunger 19 to move rearward. and bind against the connecting rod 36, holding this steering rod or connecting rod from longitudinal movement, and thus absolutely looking the steering mechanism of the ear. Furthermore, the

jaws

25 and 27 embrace the starting crank and are locked by the padlock 30 and, under these circumstances, the starting crank cannot be turned to start the machine. It is to be understood that the crank is to be pushed in against the crank shaft and turned straight down in order to lock it within the

jaws

26 and 27. When the device is unlocked, the arm 24 is shifted rearward, so as to lie upon the upper face of the body 10 and this retracts the plunger and releases the steering rod which may then be reeiprocated through the slot 12, without difficulty. It will be seen that this device makes it impossible to start the engine or .even guide the car when it is locked and will thus render impossible, the stealing of cars or the unauthorized use of cars. The device is very simple, can be easily applied to any automobile of ordinary make, and is thoroughly effective in action.

Having thus described the invention, what is claimed is 1. A locking device for motor cars, comprising a body adapted to be attached to the front axle of a motor car, the body being formed to receive the steering rod of the car, a plunger shiftable through the body into engagement with the steering rod to prevent its movement, and means for looking the plunger in its applied position.
