AUTOMATIC IGNITION CUT-OFF" WHICH OPERATES WHEN OILING SYSTEM CEASES To FUNCTION Filed Dec. 6, 1932 Inventor.
Patented Sept. 3
TO FUNCTION Albert Thibault, Bonne Madcne, Saskatchewan, Canada Application December 6, 1932, Serial No. 645,899
1 Claim.
This invention relates to all internal combustion motors equipped with pump or other forced oiling system, and has for an object, to provide means whereby the ignition circuit will be automatically broken in the event of pump or forced oiling system refusing to function due to mechanical disability or any other cause.
A further object of the invention is to provide a novel oil pressure controlled switch which will automatically cut off the ignition should. the pump or forced oiling system refuse to function.
A still further object is to provide a simple oil pressure controlled switch, inexpensive to construct, which will not easily get out of order.
With these and other objects in view the invention consists in certain novel details of construction and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to without sacrificing any of the advantages of the invention.
In the accompanying drawing forming part of these specifications, Fig. 1 shows a view of an internal combustion motor with my invention attached as it would appear when in a position for starting the motor.
Fig. 2 shows a view of the invention when the motor is running and the oil functioning.
Fig. 3 shows a view of the invention when the oil ceases to flow and the device is in position to cut off the ignition and stop the motor.
Fig. 4 is a longitudinal section of the cylinder.
Referring to the drawing in which like characters of reference designate similar parts in the various views, B designates the distributor of the ignition system thereof and in these specifications the term oil pump is used. It is to be understood however, that my invention is as applicable to magneto systems of motor ignition as to distributor and coil systems and also to motors where the oil pressure is furnished by other mechanical devices than pumps.
In order that the general relations and assembly of parts may be readily understood I have indicated in Fig. 1 an internal combustion motor with the oil filler neck A; the distributor B; the dash panel C; the starter pedal D; the oil line from the motor to the gauge on the dash panel B.
The device is illustrated in the drawing in which I is a bracket formed from a piece of metal shaped to fit snugly to the motor and held in position by the stud bolts which hold the cylinder head to the block, and to this is attached the Working parts of my invention.
A cylinder 4 of suitable size is attached to the bracket I, and within the cylinder is a piston 5 and a piston stem 6, which projects through the upper end of the cylinder and a spiral spring I, which is coiled about the piston stem 6 and interposed between the piston 5 and the upper end of the cylinder.
The cylinder head 8 is screwed on to the bottom end of the cylinder and is removable. It is provided with a nipple to which is attached the oil line 9 which is connected by a T joint IE to the oil line E of the motor which connects to the gauge on the dash panel C. The cylinder is also provided as shown with a nipple to which is attached the pipe I I connecting to the oil filler neck A, and thus provides for the return of any oil that is forced past the piston 5 to be returned to the source of supply.
The breaker arm I6 is a metal arm which is attached to the bracket I by a bolt or pin and moves freely on the same and on the under side has a notch II.
The breaker arm lifter and latch I5 is attached to the bracket I by a bolt or pin and moves freely on same. The forward part is pointed so that when raised it will fit into the notch I! in the breaker arm I6 and hold it up as shown in Fig. 1. Attached to the breaker arm lift is the rod I2 which passes to dash panel C. There is a retard spring I3, one end of which is attached to the rod I2 and the other to the dash panel C.
The rod I4 is attached to the starter pedal D and the forward end passes through a guide which is formed by bending part of the bracket I at right angles and punching a hole through it.
The rod I is attached to the starter pedal D in such a way that when the starter pedal is pressed the rod is shoved forward and presses against the breaker arm lift.
An insulated point 2 is fastened to the bracket I and an insulated cable connects this point with the distributor B.
In starting the motor by cranking the rod I 2 is shoved forward and the breaker arm lifter I5 raises the breaker arm I6 and the forward part of the breaker arm lifter I5 fits into the notch II in the lower side of the breaker arm I6 and latches it up in the position shown in Fig. 1 so that the contact between the breaker arm I6 and the insulated point 2 is broken. When using the self starter when the starter pedal is pressed the rod I4 is forced forward and pressing on the breaker arm lifter raises it and latches it up.
When the motor starts the oil pressure from the pump causes the oil to flow through the pipe Mani 9 into the cylinder 4 and impinges on the piston 5 and causes the piston and piston stem 6 to rise. The piston stem on rising raises the breaker arm l6 and the breaker arm lifter i5 is released and the retard spring It draws the rod l2 back and the breaker arm lifter returns to the position shown in Fig. 2.
Should the pressure in the oil line at any time fail, due to oil being too low or' to the oil pump ceasing to function the spring 7 will force the piston 5 and the stem 6 downward and the breaker arm will come to the position shown in Fig. 3 and will make contact with the insulated point 2 and out oi? the ignition and stop the motor.
I claim:
In combination, an internal combustion. engine with ignition and starting means and oil pressure lubrication, and a device for grounding the ignition current in case of failure of oil pressure, said device comprising a bracket adapted for attachment to the engine casing, a grounded elbow lever pivotally mounted on said bracket, an insulated ignition contact supported by said bracket and adapted for engagement with a part of'said lever, said lever having a notch adapted for engagement by a second lever also pivotally mounted on said bracket, and second lever adapted to be actuated to disconnect said elbow lever from said contact during engine starting, together with an oil pressure device mounted on said bracket, and adapted only when actuated by said oil pressure to move said elbow lever away from said ignition contact.
