This invention relates generally to means tral' after the vehicle itself has been brought for controlling the supply of fuel such as to a standstill. One embodiment of my ingasoline to internal combustion engines of vention is illustrated in the accompanying motor vehicles and consists of certain novel, drawings, in which 5 features of construction, combinations and Figure 1 is a fragmentary elevation of a 55 arrangements of parts that will be hereinmotor vehicle with a safety device embodyafter more fully described and particularly ing my invention applied thereto; pointed out in, the appended claims.

is a box rigidly mounted on the engine block and containing an electrical switch of suit minally connected to the block 21 and gearshift lever 6 and adapted to be moved by the latter for reciprocating the block, 31 is a lever pivoted intermediate its ends on the engine block and having its lower end engaging the upper face of-the collar 25 on the stem 14, and. 32 is a link terminally connected to the upper end of the lever 31 and to the lower end of the starter .pedal 8v and adapted when the pedal is depressed to cause the lever 31 to depress the stem 14 and piston 12 and thereby cause thelever 26 through engagement with the arm28 to close the switch and establish an electrical connection between the ignition switch and primary interrupter to enable the engine to operate as usual.

In use, when the lever 6 is in neutral position shown in Figure 1 and the switch in the box 27 is held in open "position so that the supply of electrical current from the ignition switch to the primary interrupter is cut off and the engine is accordingly rendered inoperative. When the lever 6 is moved to any of the positions of second, reverse, or high,.etc., the block 21 is reciprocated bythe rod 30 so that the pointed upper end '20 of the head 19 is cammed downwardly out of the groove 23. This causes the stem 14 and piston 12 to be depressed in the dash pot 10 and causes the lever 26 to be rocked about its pivot by the collar 25 to raise the rear free end of the arm 28 and thereby cause the switch to be closed to establish an elec-- trical connection from the ignition switch to the primary interrupter of the engine and permit the usual operation of the engine. In this connection itwill be noted that on the down stroke of the piston'12 the spring 18 is compressed and the follower 16 will uncover the openings 13 in the piston and escribed are in the posi will allow the oil in the dash pot to flow freely through these openings. Then when the lever 6 is returned to neutral position the block 21 will be moved longitudinally so that the groove 23 therein will be in vertical alignment with the liead 19, thus allowing the stem 14 and piston 12 to move upwardly and enabling the spring 29 to lower the arm 28 and open'the switch in the box 27. Ac-

cordin ly the supply of electrical current from the 1gn1t1on switch to the primary interrupter is cut off and the engine becomes In this connection it will be the up stroke of the piston is inoperative. noted that much slower than the down stroke since the follower 16 on the up stroke closes the openings 13. Thus, the oil in the dash pot can not flow through the piston but instead resiststhe upward movement of the piston in the said dash pot. Moreover, the period of time in which the switch can be so cut off may be readily determined and regulated by fixing the tension of the spring 18. This is also true of the down stroke of the piston,

however, the area of the openings 13 also is a factor in determining the period of time in which the piston may complete its down stroke. Furthermore, the down stroke of the piston may be effected by any movement of the lever 6 from neutral position, since movement of the rod 30 by the lever 6 will causethe block 21 to slide either forwardly or rearwardly and in doing so will depress or cam downwardly the head 19 from the groove 20 and thereby cause the stemg14 and 00 piston 12 to move downwardly.

It will also be noted that the provision of the lever 31 and link 32 forming an operating connection between the starter pedal 8 and the piston stem 14 enables the switch in the box 27 to be readily closed by the depression of the starter pedal 8 in the event the motor vehicle would of necessity, for

example onaccount of stop lights, trafiic and be required to remain motionless the like, for a greater period of time than that in which the safety device would function to cut off the supply of electrical current to the spark plugs. In other words, with my construction, operative in such an instance it might be made operative quickly by depressing the starter 8 to cause the switch to close the cir-' 'cuit and establish an electrical connection between the distributor and spark plugs and permit the usual operation of the engine. This .means prevents confusion on the part of the'operator, particularly if he is an -inexperienced operator or not familiar with the operation of the safety device and also obviates service cost. It is the natural tendency .of the driver when an engine goes dead to press upon the starter, however, I have devised the connection comprising the lever 31 and link 32 between the starter 8 1 if the engine isrendered in- 115 v mobiles.

It will prevent an operator from leaving the engine of the vehicle running for any great length of time after the operator has left the vehicle, and this aside from the dangers of asphyxiation will tend to reduce accidents with children tampering with parts of the vehicles. It will also reduce gasoline consumption now wasted by many drivers of motor vehicles, particularly delivery trucks, who are inclined to let the "engines of their vehicles run from starting time in the morning to quitting time at night. It will also reduce fire risk in auto- ,While it is believed that from the foregoing description .the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may the scope of what is claimed.
