CONTROLLING MEANS Application filed January 22, 1.920, Serial No.
My invention is an improvement in ignition cutolfs, and has for its object to pro- Vide a device of the character speci lied. especially adapted for use .in connection with the ignition s vstems of internal combustion engines, for interrupting the circuit, and wherein the cutoff is controlled b v the pres sure of the oil in the oil line.
In the dra-wings:
Figure 1 is a vertical section through the controlling mechanism of the cutotl" Figure 2 is a section at right angles to Figure 1;
Figure 3 is a. section on line 3m?, of li ure 2;
Figure l1 is a sectional view'talten on the line 1--4 of Figure 1.
Tn the present embodiment of the inreu tion` a c vlinder 1 is provided having heads 2 and 3 at its opposite ends` and the cylinder is provided with bracket lugs 4. h v means of which it mav be secured to the dash sl'ioard 5 of a motor vehicle for instance.
A plunger 6 is arranged within the easing constituted bv the cvlinder and the heads. and this plunger which has the usual paching rings has connected therewith a stem or rod 7 which extends through a packing in the head 2.
A coil spring 8 is arranged between the head 2 and the plunger and acts noriuallv to force the plunger downward. The cylinder 1 is .interposed in the oil line of the motor not shown. and the said cvlinder has an iulet 9 and an outlet 10 for the oil. the outlet being spaced above the inlet. as shown` and when there is no pressure in the evliuder beneath the plunger the spring will force the plunger' down cutting olf the in take. from the outlet.
A shaft 11, which controls the cutoff switch not shown is iournaled in the dashboard 5. and this shaft has a crank arm 12 in front of the dash-board which is con i nected to the stem 7 of the plunger hv a link 13. As showiny the link is longitudiuall),Y Slotted, and the crank arm has a pin 111- engaging in the slot providing a lostmotion connection between the and the plunger. A head 15 is secured to the shaft 11 in front of the dash-board. and a coil spring 16 is arranged in the recess 17 in FOR GNITION CUT-GEES.

the front face of the dash-board about the shaft. the spring bearing at one end against stop on the Shaft. and at the other end against an escuteheon 18 on the dash-board. The spring holds the button or knob 15 in close contact with the escutcheon.
The operation of the device is as follows:
The ignition circuit not shown of the internal combustion engine with which the present device is associated should be so arranged or connected that upon the arm 12 being brought to a raised position as shown in Figure 2 of the drawings, the ignition circuit will be closed and upon this arm bedrawn downwardlj,T or lowered the ignition circuit should be opened. Assuming this to be the case when oil pressure exists in the lower end ofthe c vlinder 1 the plunger 6 will be forced upwardlv until the opening .10 is uncovered and will remain in this posi tion long` as the pressure of oil is maintained therebeneath. The spring 16 will vieldinglv hold the shaft 11 in its adiusted position. lVhen the pressure of the oil falls below a predetermined point the spring 8 will force the plunger downwardly shutting oli" the oil suppl)T through the opening- 10 and the linlr 13 will sin'iultaneousllv draw downwardh,7 the arm 12 to such a` position that 'the ignition circuit will be opened. So long as the pressure in the oil line is at a. predetermined degree the ignition circuit. ma)vv be maintaiiled closed. ltis therefore impossible to operate the engine of the motor vehicle unless there is suliieient oil for lubricating the different parts of the same. The present device also makes it impossible to leave the ignition Current on when the enginenot running.
l claim:
A device of the character described coinprising a c vlinder having an inlet adjacentits one end adapted to be connected to an oil pump of au internal combustion engine and having an outlet intermediate `its ends. a spring-pressed piston within the` @vlinder adapted to uormallv prevent communication between the inlet and outlet of the cylinder and adapted to move within the cylinder under influence of oil pressure from said pump and assmne :1 position for establishing communication between the said inlet and being of such length that when the arm is in one of its adjusted positions and upon the piston assuming its normal or closed position the shaft carrying said ai'ln will be 1'0- tatetl a predetermined degree.
