To all whom it may conccm:

Be it known that 1, JAMES TAYLOR, a citizen of the United States, and a resident of the city of New York, borough of Man hattan, in the county and State of New York, have invented a new and Improved Lock for Motors, of which the following is full, clear, and exact description.

The present invention relates to new and useful improvements in devices for locking motor vehicles, and itpertains more particularly to a mechanism adapted to render inoperative the fuel and ignition supply system of the motor of said vehicle.

It is one of the primary objects of the present invention to provide a device whereby the supply of fuel to a carbureter of the internal combustion motor may be entirely shut off, thus rendering the motor inoperative.

It is a further object of the invention'to provide means in combination with the fuel control :tor breaking the ignition circuit to further render the motor inoperative.

It is a further object of the invention to provide a device which includes a looking mechanism constructed in such a manner that after it ha once been opened, the key may be removeththe structure being such as to permit oil an automatic locking of the mechanism when moved to the inoperative position.

It is a still further object of the present invention to so construct a device of this character that the same will be readily adaptable to motor vehicles at present in use without materially changing their mechanisms or designs.

With the above and other objects in view, reference is had to the accompanying drawings, in which Figure 1 is a front elevation partly broken away of a device constructed in ac cordance with the present invention;

Fig. 2 isa longitudinal. sectional view thereof;

Fig. 3 is a detail top plan view;

Fig. 4 is a sectionl View taken on the line itof Fig. 2, with the several parts in their locked position;

Fig. 5 is a similar view with the parts in their. open position; v

Fig. 6 is a detail sectional view taken on the line 6-6 of Fig. 2, with the-parts of the locking mechanism in their locked position;

Fig. 7 is a similar View with, the parts in their open position;

Fig. 8 is a rear elevation or the device Referring more particularly to the drawings, the. gas line of the motor is indicated by the reference character 10, and mounted in said gas line 10, is a valve chamber 11. lhis valve chamber 11 has an inletpassage 13 and an outlet passage 12, and'has its bottom wall closed by means of a plug 1%, said plug serving to permit of access to the chamber 11 for the purpose of draining and cleaning the same. liteciprocatively mounted within the chamber 11, is a piston valve 15, and said piston valve is adapted to open the inlet 13 to the outlet 12, or to close communication between the inlet and outlet ports depending upon its position in the chamber or casing 11. Projecting vertically from the casing 11 is a tubular member 16, and fitting in the upper end of said tubular member 16 is a flexible tubular member 17, upon the upper end of which is secured another tubular member 18.

Mounted upon the upper end of the tubular member 18 is the yoke extension 19 of a housing 20, said housing being circular in cross sectional form. Mounted in the hous ing 20 is a rotating member 21, and said rotating member is provided with thumb pieces 22, by means of which it is grasped in order that it may be rotated.

Projecting from the rear face of the rotating member 21, is a pin 23 and pivotally connected to said pin 23, is a crank or lever 24. The lower end of this crank or lever 24: is bifurcated as at 25, and mounted in the bifurcated end 25 of said crank 24:, is a tubular member 26. This tubular member 26 is connected to a flexible shaft 27, the lower end of which is secured within a tubular member 28, which in turn is secured to the valve member 15 by means of a bolt or the like 29. I

By this construction it will be noted that as the member 21 is rotated within the housing 20, through the medium of the flexible sha t 27 and its several connections and the crank 24, the valve member 15 will be reciprocated in the valve chamber 11 to either open or close the outlet port 12.

The rotating member 21 has a tubular extension 30 and mounted in said tubular extension 30 is a lock 31, which look is adapted to be operated by means of akey inserted into the keyhole slot 32. The keyhole slot 32 is adapted to be protected from the -weather by means of, a cover plate. 33, and

' ected into .a recess 41 through one of the Walls of the rotating member 21, to prevent rotary movement of the said member 21 in its mounting." -This reciprocating member 40 .is rigidly mounted in a housing 42, and

interposed between said housing and a cup 43, is a coil spring 44, which coil spring serves to maintain the reciprocating mem ber 40 in the recess 41 when the same are in register with each other. In order to position the plunger 40 within the rotating member 21, a closing bolt 45 is employed, said bolt having screw-threaded engagement with an opening in the top of the housing 20.

The lock 31 is adapted to actuate a cam member 46 and in its rotation said cam member 46 is adapted to engage the housing 42 to move the reciprocating member 40 out of the recess 41 to permit of a free movement of the rotary member 21 within the housing 20. The housing 20 is provided at opposite points on its interior with lugs 52 and 53, and carried by the rotating member 21 in such position as to engage these lugs to limit the rotating movement of the member 21, is a projecting pin or lug 55.

The reference character 56 designates a rear closing plate for the housing 20, and mounted as shown in Fig. 6 on said rear closing plate 56, are two curved springs 57 and 58. These curved springs 57 and 58 are each retained in position by means of a screw 59 and are positioned adjacent the lug 52 in such a manner that as the pin engages said lug 52, it will pass between the springs 57 and 58 in contact therewith as shown in Fig. 7.

The screws 59 which secure the spring members 57 and 58 in position on the rear closing plate 56, project through said closing plate 56 as indicated by the reference character 60 and provide the terminals or binding posts for the wires of the igni tion circuit. 7

Assuming that the valve member 15 is in the position shown in Fig. 2 and the several parts of the locking mechanism are in their secured positions, the operation of the device is as follows:

The plate 33 is elevated and a key inserted into thekeyhole slot 32. Upon turningth'e key in the slot 32, the lock member 31 will be" rotated and through the medium of the cam 46, the reciprocating member 40 will be withdrawn from the recess 41 to the position which will permit of a free turn ing of the rotating member 21 within the housing 20. After. the reciprocating mem- Simultaneously with this operation, the

pin 55 passesbetween the springs 57 and 58 and completes the electrical circuit in order that proper ignition may be had. After this operation takes place, the key is rotated backwardly to a position where the cam is moved to the position shown inFig. 4. in this position, however, owing tothe fact that the rotating member 21 has not been moved, the free end of the reciprocating member 40 will engage the inner wall of the housing 20 and will not interfere with the proper rotation of the member 21.

When it is desired to lock thelnotor, it will only be necessary to grasp the thumb pieces 22, rotate the rotary member 21 anticlockwise until it reaches such a position that the end of the reciprocating member 40 will enter the recess 41 and hold all of the parts in their locked position. Simul taneously with this operation, the pin 55 will passfrom between the springs 57 and 58, thus breaking the electrical circuit and rendering the ignition system of the motor inoperative. I i

It is to be understood that the terminals 60 of the wire 70 of the ignition circuit may be suitably insulated in orderthat the proper results may be had.

While in the present instance the invention has been described as pertaining particularly to motors for motor vehicles, it is obvious that thesame is capable of use in connection with fluid lines and electrical circuits generally and is not. limited to: use

in controlling the supply of fuel and current r to internal combustion motors.
