Application Ji'ilcd Apri1'18, 1925. "Serial No. 24,109.

To all whom it may concern:

Be it known that I. MATTHEW HARRING- 'roN. a citizen of the United States, residing and State.

engine when it is to {be started, whereby the initial combustible charges are more readily formed, the engine being afterwards operated'by volatile fluid in usual manner.

In carrying out my invention I utilize a valved coupling preferably located .in the intake manifold of the internal combustion engine and forming anormally closed permanent fixture. In connection With the coupling I utilize a separate supplydevice for temporary attachment to the coupling for supplying the initial charges to the engine, and means are provided for automatically opening and closing the valved coupling to'the manifold.

The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully set forth and claimed.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention wherein one mode is illustrated for carrying out the principles of my invention.

Figure 1 is a view showing a portion of an intake manifold and a carbureter for an internal combustion engine with the device of my invention applied thereto.

Figure 2 is an enlarged detail sectional view of the valved coupling of the manifold showing the actuating nozzle applied thereto.

Figure 3 is a detail of the locking device for the gas spout and gas tank.

Figure at is a vertical sectional view of the acetylene gas tank which may be used for supplying the starting gas or charges for the engine.

In carrying out my invention I have shown I a carbureter 1 and intake manifold 2 in Figure l of usual type, and the manifold or other suitable intake device for the engine cylinders is provided with a permanent coupling 3 in the form of a tubular casting having exterior threads 4 for complementary threads in the Wall of the screwing into 1nanifold,and it will be obvious of coursethat the coupling is located between the can bureter and the engine.

The inner end of the coupling is provided witha valve seat 5 within the manifold, and this seat is normally closed by an inwardly opening valve 6 outwardly through the coupling. O-n the outer end of the stem is provided :an open head or ring 8 flxed as by a pin 9 tothe stem,

and this head is'slidable in the coupling .as'

the valve is opened or closedpas indicated by dotted lines in Figure 2.

Between the wall of the valve seat5 in'zthe coupling and the hollow head 8 is interposed a spring 10 coiled aboutthe stem and designed to normally force the headoutwardly and hold the valve on its seat. Onthefouter face of this open head is attached by su'it able, means a washer or gasket 11 to form a cushion and prevent leak of the starting gas from the coupling.

\Vhile any suitable gas may be employed for the starting combustible charge I find that acetylene gas is convenient and may be used with facility. I I prefer touse a portable, hand manipulated generator for the acetylene gas, in the form of a tank or cup 12, which has a top outlet opening and arouate locking flanges 13 about the opening.

A detachable spout 14 is provided for the tank and the spout is fashioned with arcuate flanges 15 so that the spout may readily be locked to the tank or unlocked therefrom when the tank is not in use.

The spout is of angular shape with a reduced nozzle and on the exterior of the nozzle I provide a hooked shaped lug 16 which is adapted for insertion in the curved flange 17 fashioned at the outer end of the coupling or hollow casting 3. The tank is manipulated by use of the handle 18, and it will be apparent that when the nozzle is entered in the open outer end of the coupling (as indicated by dotted lines in Figure 2 with the hooked-lug in the curved flange) and the nozzle turned 'down to dotted line position, this action will push in the head 8 and open the valve 6. In this position the valve spring 10 is compressed and gas is permitted to flow through the nozzle and couplingto be sucked into the manifold and engine cylinder. lVith the ignition system in operation the starting charges are exploded to operate the engine.

having a stem 7 extending After the engine is started the nozzle is Withdrawn from the coupling and the valve 6 is automatically returned to its seat, and the engine is operated in usual manner.

For generating the acetylene gas in the tank or cup I provide a cage 19 for the calcium carbide and a separate water tank 20 With a water passage 21 to the generating chamber. The generation of gas is controlled by use or a valve 22 having a hand wheel 23 outside the tank for manual control.

When not in use the spout is detached from the tank and a closure may be applied to its outlet, and the tank and spout may be carried on an automobile as an accessory. Under normal conditions the valve 6 is closed by its spring and retained in such position against access of air to the manifold.

The hollow slide head of the valve stem is normally held within the outer open end of the coupling and protected by the overhanging curved attaching flange 17 for the nozzle of the spout 14, and it will be apparent that this additional elementthe coupling may be attached to the manifold without disturbing the relative arrangement of the usual feed system for gas to the interior of the engine.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is- 1. The combination with the intake manifold of an internal combustion engine, a coupling fixed thereto, a normally closed valve in said coupling, and means on the coupling for receiving a supply nozzle, of a tank and means therein for generating gas, and a supply nozzle on the tank for coaction With the coupling for opening said valve.

2. The combination with an intake mani fold having a laterally extending cylindrical valve casing with a spring pressed normally closed valve having a stem extending through said casing, an annular head on said stem, a curved flange on the outer end of said casing, a supply nozzle adapted for insertion within said casing to move said head for opening the valve, and a lug on said nozzle for guiding engagement under the curved flange of said valve casing.

In testimony whereof I aflix my signature.

MATTHEW HARRINGTON.
