PRIMING-CUP FOR GASOLENE-ENGINES.

Specification of Letters Patent.

Patented March 16, 1909.

Application filed December 7, 1908. -Seria1 No. 466,224.

To all whom 'it may concern.'

Be it known that I, CHARLES ll. WisNER, a citizen of the United States, residing at Flint, county of Genesee, State of Michigan, have invented a certain new and useful Inipr `ve1nent in Priining-Cups for Gasolene- Engines, and declare the following to be a full, clear, and exact description of the saine, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which Jform a part of this specification.

My invention relates to a priming cup for gasolene engines, and an object of n iy improvements is to provide an improved apparatus for supplying the gasolene for starting the engine, or for causing a surplus of gaso- Iene to be removed from the cylinder.

In the accompzniying drawings :l `igure l, is an elevation of a two cylinder' gasolene engine, having a priming cup attached thereto embodying my invention. Fig. 2, is an elevation of the priming cup, the upper part of the reservoir being cut away, and the handle of the cup being indicated in different positions. Fig. 3, is a vertical section of the cook, longitudinal of the plug thereof, and the lower part of the reservoir, the plug being turned to i its completely closed position. Fig. 4, is a vertical section, similar to Fig. 3, but showing the entire reservoir, the plug of the cock being turned to a position at which both air and gasolene will be taken into the engine cylinder. Fig. 5, is a section similar V-to Fig. 3, the plug of the cock being turned to a position 1n which gasolene alone is being y fed tothe engine cylinder. Fig. 6, is a section similar to Fig. 3, 'the plug being turned to a posltion 1n which air alone 1s admitted to the engine cylinder. Fig. 7, is a section of" the cock and lower part of the reservoir, taken in a plane at right angles to that of Fig. 6, the plug being 1n the position of the latter figure.

The reference letter A indicates the entire priming cup, which is located between the carbureter and the intake' valveof the engine.

a., c, are the cylindersoi a gasolene engine.

b is the intake pipe leading from the carbureter e, and'extending in branches b1, b2, to the two cylinders. The priming cupl A is located adjacent to the junction of the branches t1, and b2, so that it delivers gason lene into the intake pipe where it will be taken into either cylinder upon. the suction stroke of said cylinder.

c is a reservoir for gasolene.

d, e, are apertures, or ducts, through the bottom of the reservoir c.

i is the casing of a cock upon the lower end of the reservoir c.

t is an intake opening for atmospheric air in the casing i, and g is a passage leading from said casing into the intake pipe to the engine cylinders.

f is a conical plug fitting into the 'casing i, and held with its surface contiguous to the inner surface 'of said casing by a spring f1, and washer f2, in the usual way.

g is an axial cylindrical aperture formed in the plug f from its larger end, and coin n'runicating with the transverse opening 7s at the center oi the plug f. The inner portion oi the aperture forms a duct for gasolenc.

7' is a valve seat formed in the aperture g.

is a needle valve stein having screw threads engaging threads in the aperture g, its inner end being adapted to close upon the valve seat j, or to regulate the size of the passage between the aperture g and thetransverse opening r is a passage or duct extending at right angles from the aperture g to the periphery of the plug f, its outer end being adapted to register with the aperture d in the bottom of the reservoir c. y

m is an axial, aperture or duct extending in line with the aperture y, upon the opposite side of the opening lr.

n is a radial passage or duct extending from the inner end of the passage 1n to the periphery of the plug f, its outer end adapted to register with the aperture e in the bottoni of the reservoir c.

s is aslnall passage, or duct, extendingiroin the opening k at the center thereof, radially to the periphery of the plug A1 is a nozzle located at the top ol the res ervoir c by which the same may be filled.

o is a stopper adapted to close the nozzle Al.

-wjs an eye formed at thc lower end oi' the stopper o. l bend a resilientJ wire to iorm two parallel legs r, fr, with their ends turned outward to 'forni lugs y, y, and pass it through the eye w. By pressing the legs x, together, the lugs y, y, may be passed through the opening of the nozzle A1, and when the legs fr, :11, spring` apart, said lugs will prevent the removal of the stopper, except so tar as necessary to perinit theiillingoi the reservoir.

The operation of the above described device is as 'follo\\fs:-During the ordinary operttionid the engine, the plug f is turned to the position indicated by p1 in Fig. 3, at which position the various passages are all closed, as indicated in Fig. 3. Should it be desired to 'leed both air and gasolene to the engine through this apparatus,j the plug f is turned to the position indicated by p2 in Fig. 2, at which position the passage lr will register with the aperture d, and the opening 7.x' will be in position to admit air ireely,as indicated in Fig. 7, although in the latter iigure, the plug fis turned to a-position 180 degrees from that at which it is located in Fig. 4. The rate at which the gasolene flows in this position will be regulated by the needle valve stem lz.. Should it be desired to ieed gasolene only to the engine, the plug f is turned to the posi-l tion "i oi Fig. 2, when the passages are in the position indicated in Fig. 5, the passage '1t registering with the aperture e, and the passage s con'iinunieating with the deliveryT passage q, so that gasolene will ru-n through n and' m into 7c, and be delivered to the engine through the passages s and q. Should too much gasolene have been fed to the engine, the plug f Will he turned to the position indicated in Figs` 6 and 7, at which there will be a free opening for atmospheric air to the 'cylindenand the passages for gasolene will be closed. Thus the engine will take in pure air and discharge air and gasoleiie, until the surplus gasolene is evaporated and removed.

'It desired, kerosene may be fedto the cylinden-for cleaning the same, by the above descri-bed apparatus.

' What I claim is 1. The combination with an engine having an intake passage and a carbureter and intake valve in said passage, of a priming cup having an air passage and a gasolene duct communicating with said intake passage between said carbureter and valve, and means for opening and closing said air passage, and means for opening and closing said duct.
