' Application tiled M129, 1926'. serialno. 105,472,
This linventionrelates to priming devices for internal combustion engines, and has for one offits objects, to provide a novel, simple 7. and inexpensive device of this character that a can be readily installed and connected to the gasoline discharge'port'of a vacuum tank and to'the spark plugs oft-the engine, that shall be safe against back pressure and back fire,
and that shall be'cap-able of being readily,
lo controlled from-the drivers seat of. an automobile f With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of 16 parts hereinafter fully described and claimed,
and illustrated in the accompanying drawing, wherein:
Figure 1 is a view partly in elevatlon and partly in vertical section illustrating the ap a plication of an engine priming device embodying my invention,
Figure 2 is a detail sectional view taken on the plane indicated by the line 2-2 of Figure 1,
25 Figure 3 is a detail sectional view illustrating the manner in which the priming device is adapted to be connected to the spark plugs of the engine,
Figure 4 is a detail sectional view taken on :0 the planeindicated by the line 4-4 of Figure 1, and Figure is a detail sectional View of one of the check valves of the device.
Corresponding and like parts are referred 35 to in the following description, and designated in the several views of the accompanying drawing, by similar reference characters.
In the drawing, 1 designates the cylinder block, 2 the sparklplugs, 3 the intake maniw fold and 4 the carburetor of an internal combustion engine. 5 designates a vacuum tank and 6 a tube leading from the vacuum tank to the carburetor 4. All these parts are of well known construction, and in addition 46 thereto there is shown in the drawing the dash 7 and instrument board 8 of an automobile. The priming device comprises a tank 9 which is secured to the dash 7 by brackets 10. The tank 9 is supplied with gasoline from the vacuum tank 5 by a tube 11 which communicates with the gasoline discharge port of the vacuum tank 5 and with the upper end of the tank 9 and is provided with a check valve 12. A tube 13 communicates with the intake manifold 3 and with the upper end of the tank9 and is provided with acheckvalve 14. The check valves 12 and 14 are similar in construction and open in the direction indicated by the arrows in Figure 1.. 'As shown in Figure 5, each of the check valves 12 and 14 comprises a casing 14 fullyopen at one end and provided. with a'rest'ricted opening'14 at the other. The opening 14 is of conical formation, and cooperating therewith is a needle valve 14 Whichi's carried by a head 14 slidably mounted within the casing14 and p-rovided with openings or ports 14 The needle valve 14 and its head 14 move withinthe casing 14 between that end of the casing provided with the opening 14 and a stop screw 14 which is removable to permit the removal of the needle valve and its head.
A vertical pipe'15 supported by a bracket 16 secured to the tank 9, communicates at its lower end with the corresponding end of this tank and is provided at its upper end with a distributing head Tubes 17 communicate with the distributing head 15 and with the interior of the spark plugs 2. The tubes 17 are of sectional formation and the sections thereof are connected with their adjacent ends in relatively spaced relation by means of sleeves 18 made of rubber or any other.
suitable material that is a non-conductor of electricity. The spark plugs 2 are provided with nipples 19 and the tubes 17 are connected to the nipples by coupling nuts 20. The tube 15 is provided with a valve 21 by means of which the amount of gasoline flowing from the tank 9 to the distributing head 15 can be controlled. A cut-olfva-lve 22 is also mounted in the tube 15, and is normallyheld closed by a spring 23 which is secured to an arm 24 carried by the bracket-16 and an arm 25 secured to the plug of the valve. The valve 22 may be opened from the drivers seat of the automobile by means of a rod 26 passing through the instrument board 8 and pro: vided at its rear end with a handle 27. The front end of the rod 26 is connected to the plug of the valve 22 by an arm 28. A downwardly seating check valve 29 is mounted in the pipe 15, and a screen 30 is mounted in the distributing head 15 As the tank 9 is in communication with the intake manifold 3 by way of the pipe 13, the
so i
engine will when in operation create a pargine, the valve 22 is opened through the me dium of the rod 26, and when this has been done the gasoline Will flow to the distributing head and from said head .to the engine cylinders by Way of thetubes 17 and screen 30 prevents the ignition of any gasoline in the distributing head.
It should be understood that the drawing islmer ely illustrative and does not pretend to give exact proportions. Furthermore, the. said drawing is illustrative offa preferred construction, it being my expectation that various changes and modifications may be made Withoutdeparting from the spirit and v scope of my invention.
What is claimed is In combination, an internal combustion engine and the spark plugs thereof, a tank, a vertically disposed pipe communicating at its lower end With the tank and provided at its upper end With a distributing head, a bracket for supporting-the pipe and secured to the tank, a downwardly seating check valve"arranged"within the pipe below the distributing head, a manually operable .valve located in the pipe below the'check valve, tubes coinmunicatingvvith' the distributing head and With the spark plugs, a sourceof fuel supply for the engine, a pipe provided with a check valve and communicatingjiyvith said source" and the top of the tank, and a se'c 0nd pipe provided with a check valve and communicating?yvith'the topof the tank and With theint'ake manifold of the engine. 7,
