To all whom it may. concern";

Be it known that L FRA N Envo, "J12, citizen of the United States, residing-at Geyserville, in the county of-Sonoma and State of California, have'invented new and useful Improvements in- Engine-Primers, of

which the followingis aspecification...

This invention relates to internal combus tion engines, particularly to priming devices therefor, and has for its object the PI'OVlSlOIl of means'whereby a'charge of-gasolene may be allowed toflow into all theeylindersfst' multaneously'without the operators leaving the driving seat, whereby to-facilitate starting the, engine .in. cold weather.; -s 7 I An important object is the provision of a device of this character including very simply and easily operated means {whereby all the primingqcups associated. with the cylinders may be, simultaneously opened and separately controlled means. whereby. a

variable quantity of gasolene or other fuel may be admitted to'the cylinders. I

A further, ob'ect is the provision of a device of this characterwh-ich is provided with stop means whereby the operator may ascertain, without looking, whether ;or notthe ple and inexpensive in priming cups are intheir open or closed po- SltlOIlS. Ji' I Anadditional object'isEtheprovision of a device of this character which will 'be simmanufacture, highly efficientin service, durable in use, easily installed and a general improvement of the With the above and otherobjects and advantages in view ,'the inventionconsistszin the details of construction to be hereinafter... more fully described and claimed, and illustrated in the accompanying drawings in which V I Figure 1 is a side elevation of an internal combustion engine showing my device applied thereto.

Fig. 2 is a sectional view on the line 22 of Fig.1.

Fig. 3 is a front elevation of the priming tank.

Fig. 4 is a detail elevation of one of the primln cups showing the stop member as sociate therewith and Fig. 5 is a detail view of the priming cup ing the letter A designates the front portion of an automobile and B designates a n @siiefi ii eue re Patented Mar. 18,1919. Application filed A gustes, 1 18., Serial No. 251,177.

broadly-by the letter D communicating with the cylinders of the engine. Each of these primingicups D comprises a valve body 10 provided at its lower end with a nipple 11 threadedinto the cylinder head of the engine and having a valve stem 12 upon the end of which is mounted a sprocket wheel 13; .A chain 14 is trained about all ofthe sprocket wheels 13 and extends through suitable openingsin the dash E of the automobile and is trained about a sprocket 15 mounted upon a bracket 16, secured upon the .front of the dash. The sprocket 15 is secured upon a shaft 17 .to which is secured a treadle 18 de;

pressionof which will cause partial rotation ofthe shaft 17 and the sprocket 15. The shaft 17 further carries a shoe 19 which is engaged by a leaf spring 20 secured upon the dash for returning the shaft to itsoriginal position, after depression. From the above, it, will be seen thatdepression of the pedal ortreadle-18by the operator will result in movement of the chain 14 which will turn all of the sprockets l3 and consequently open the valves in the priming cups D.

I In order to provide means whereby the valves in the priming cups will be opened to the proper extent, I provide upon one of the sprockets 13an arm 21- which will engageagainst opposite sides of an upstanding nipple 22 formed on the priming cu body .110. -Engagement of the arm 21 with this ',;nipple will prevent further movement of the sprocket 13.

Each of the priming cups 10 is provided with the nipple 22 to which is connected by a suitable union 23 a pipe 24. All the pipes 24 extend in parallel relation to each other and extend through a suitable opening in the dash E and communicate with the bottom of a priming tank 25 suitably mounted adjacent the dash E. At the points where the pipes 24 enter the bottom of the tank 25, are formed valve seats 26 normally closed by valves 27 secured upon the lower ends of vertically extending rods 28 WlllOh'GXtBIlCl upwardly and terminate albOVe the top of the tank 25. The tank 25 is of course provided with a suitable filling opening closed by any ordinary form of cap and is adapted to contain the gasolene or other fuel with which the engine is to be primed. A coil spring 29 is disposed about each of the rods 28 and normally holdsthe valve 27 in a position to close the opening. At each end, the tank has secured thereon an upstanding bracket or yoke 30 which is bifurcated as shown'and which is provided'at one side with a plurality of teeth 31 meshing with pinions 3" secured upon the ends of a shaft 38 which extends -through eyes '34: formed on'the upper ends of the rods 28. Gneend of the shaft 33 is provided With-a crank 3et bymeans of which the shaft may be rotated.

In the operation of the device, after the opera-tor *has pressed atpon the treadle 18 to open the primin 'cups, :the crank 8% is grasped and turned, whereupon engagement of tl16plIllOl1S 32 with the teeth '31 on :the brackets will causethe shaft 33 tomove upwardly, pulling the rods 28 upwardly and lifting the valves 27 from the seats 26 against the resilience of the springs '29. The gasolene or other fuel stored 'Within the tank 25 'Will then pass "through the tubesQd: and be discharged 111t9'tl1BipIlH1l11g cups 'D from which it will pass into the cylinders of the engine. iVhen the engine has been primed, release of the crank handle 3d "will permit the springs to return Ethe valves 27 to their original positions closing the openings to the pipes 24.

From the foregoing description and :a study of the drawings it will be apparent that I have thus providedn very sim'pledevice by means of which the cylinders of an internal combustion engine 1118;) be very quickly and QilSllY primed to facilitate starting in eold weather o'r forany other desired purpose.

RVhil 1 have shown and described the preferred embodiment of my invention, it Will-of course be readily understood that It reservethe-rightto make such eh'a-irges-in'the form, construction and arrangements of Genius cfthispetent he obtained tori-five c rts e' nee'aeee parts as will not depart from the spirit of the invention nor the scope of the subjoined --cla-1ms.'
