CALIFQRHI.

To all who/Init may concern:

Be it known that We, Lnucnvzi. JoHNsoN and HARRY M. Marriens,' 'citiaens of the United States, countyo Siskiyou and State of California, have invented certain new and useful linprovenients in Primers, of which the following is a specification.; reference being had te the accompanying drawings.

for internal combustion engines and has for its principal object to produce a simple, eili- `cient and reliable hand operated device of this character particularly vdesigned for use 15 pon .motorcycles and similar vehicles,

whereby the'cylinders of the engine may be properly primed when necessary.

Our invention has for a further and more speciiic object to provide a spring pressed plunger operating in a suitable cylindera said cylinder being mounted upon a base7 provided with a passage for the gasolene., a

connection between the base and the intake manifold of vthe engi-ne, a connection between the base and the gasolene supply tank, Valves arranged in said connections and noi.1- mally closing communication between the same and the base and adapted to be alter- 'nately opened and closed in the movemento the plunger in opposite directionssaidplunger being providedwith an extension to normally close the passageway in said base,' and thereby prevent leakage.V of the gasolene through the same and the engine cylinders.

The invention has'for a furtherohject to produce a device for the above purpose i which may be easily operated., will occupy but small space upon the vehicle and can be manufactured at comparatively Small cost.

With the abo-ve and other objects in view, the invention consists in the novel features of construction andthe 'combination and ar- `rangement of parts'to be hereinafter more fully describedrpointed outin the claim and shown in the accompanying 'dra\ vings, in

A coil` spring 12 of the requisite tensile strength is located around the rod 8 within the casing land bears at its lower end against the plunger l() and at its upper vend against the cap 7 of the cylinder. Adjacent the upper end or' the cylinder,, the same is provided in'vits body Wall Wit-li a suitable air outlet opening 13. I 'i '4 i v f The hase 6 is centrally formed with a passage lll, the intermediate portion of which is relatively narrow, said passage being 'larecl at its upper end, as indicated at l5,- to proifide a seat for the needle point -ll ofthe plunger rod 8.v This 'upper flared'end of the passage'la opens into a circular chamber 16 formed in the hase@ in which the lower .end of the cylinder 5 is detacltably mounted. as above stated. v'lhelower end sage 14 on the opposite sideof -its narrow central portion is also dared as indicated at 17 to provide a seat for the Avalve ball 18. 19 indicates aconnec'ting nipple which has `in .the-head G and able connection with the intake manifold of the. engine.l an intericr annular shoulder 20 against which one end cfa lvalve spring :2l"seats.
