3.1 invention relates to gas engine primers ne ype wherein a small pump is mount on the dash eoardof en automobile and "Mous fuel .into the engine cylinders prenery 'lo sterling the engine ishereof. The

.i perle o' bhe invention, and alley alone hewn and described. is eroublesonie in primers of l'his type "ovide e simple and secure means of ing the primer closed to prevent; vany ge during, the normal operation of'the rlne., and thus the admission of an over )ply of gas to: elle engine. Furthermore en locking means as is provided should quick and sensible to the touch so that operator can tell when the primer is .osed by the feel, and so that lie can ecplish the closure with a partiel lern Zie plunger heed.

The cylinder l of the device is provided with screw-threads on which ere screwed the dash board nues 2 and 3. These' nts are adapted to engage one on one sidf` wendl the other on the other side or" the entende# bile dash fl, to hold the cylinder in piece en the said dash Within'ea-sy reach of lie operster of the machine. 'A plunger .5 having a knurled operating heed 6, is mounted in the cylinder so theft il, een he reciproeased lili to force e spray of ,qa-soleils ini lelie nieni.-

fold or any desiredperl'. oro elle engine of the cer-(not shown).

A fitting 7 is provided which is prelersblgf soldered ono the end or' the cylinder. This litting has a central chamber 8 surrounded by shoulder 9 to abut the cylinder, and lies an inlet pori'. 10 and an outlet pori? il. A lubular'extension l2 of the ittlng has communication with the inlet pori; end has n small ball check 13 and a screwtlireaded end ll to receive a, small union coupling l5.

avided and adapted to screw into the open end of the extension l2.

Another extension 1,7 formed in itting which communicates with elle cules port. above mentioned. and ellis enension has a. `like screwthreaded porlion 3.8 for ille union coupling 19. and lies likewise s. ehe-ol; 20. The check plus 2l. ci this ene, how- .As is cusornary, the checlr plug 16 is 'proever, enters et right angles lo elle tubular extension. lt is desired for purposes of clearance to lieve elle ener-lures yfor 'nlie 'check plugs undercue e622 (Fig. El).

The inner end of elle plunger is bored ourJ et Q4, and s springs 2o is mounted in the bored out portion. The pin 2li lies a disk 27 to slide in lie bored oni; pcrion, sind a cap :28 leaving an aperure lslirougli which the pin passes and-is guided., is secured over the end of the plunger., preferably by @breeding seid cec and plunger. The cap .also holds the disk at the end of elle ein from coming out of the plunger, and lie 'pin is of a length thai; it will seele in lie inlet, port 1G end close it oil' lielore the plunger is pushed into locking position as Will be described.

A Stalling box 29 is screvvthreaded ontolghe outer end of elle plunger and packing 30 lil@ iaV

3l as is customary. The box has a flange 3L) at its outer extremity, oft' asize to fit the plunger and has a notch 15S-cut in it to receive the pin *2-l on the plunger, The {iange around this notch is bent inwardly at 34?, 3l, so as to form a ratchet which will engage the pin once it' is pushed through ythe notch and given a slight turn so as to iride over the inward extension. A washer 31a, seated in the end of the cylinder, contines the packing, and also serves as a stop for the plunger by presenting an abutment to the edge of the cap 2S.

flhe depression on the outside also servers;

to guide the pin into thenotch by touch, the ratchet within also telling by-'touch when the plunger is lockedin, and prevent-l with a cylinder, a plunger therefor, the cylinder provided with a port, means for closing the port, means for mounting the port closing means in the plunger so as to be mov- .p'oi-t, said means beingv extensible and' spring-pressed so 'as to allow movement of the plunger after the said meansis in closing ing the pin from riding by the notch when' it is desired to release the plunger.

'It can thus be readily ap4 reciated that when it is desired to operate tieprnner; the

plungeiis released and pushed in and entf.

drawing liquid fuelin through` the inlet port and forcing it out" through the outlet. Then itis desired to lock the primer, the plunger is pressed in so that the liaiige and pin engage each other and turned until the pin4 rides down through the notch in the flange. By this time the "pin will'liave".

been brought to its seat the disk 27 will have been forced up in the bored out portion of the plunger. The plunger is turned slightly at thisjunctureso that the c pin will ride over the ratchet formed within the flange and the spring will prevent tlie plunger from jarring loose because it will work against the ratchet in its tendency to force the plunger outwardly.

ln the/absence of the ratchet, the spring will serve as' aineans for preventing the plunger from jarring out, and if the 'ratchet were omitted, a partially practical device would be furnished by reason-of the spring.

.in the bored out portion, and a spring in position andjmeans for locking the plunger, said port closing means adapted to seat bevfore the lock takes effect in the operation of the plunger.

4. ln a device of the character described, in combination with'a cylinder and a 'plunger therefor, the cylinder provided with a port, a bored out-portion in said plunger, a meansfor closing'said port slidably mounted said bored out portion to hold said means in extended position and means for locking the plun er, said port closing means adapted to seat efore the lock taires eect in the operation vott the plunger. c

5. In a device of the character described, in combination with a cylinder and a'plunger therefor,r the cylinder provided with a port, means on the plunger for closing said gaa port, saidineans being extensible and springpressed so as to allow movement oi the plun- `ger after the said means is in closing posil tion, a pin on the plunger, and a flange hav- Ho'wever, the ratchet is an additional se-.

curity as wel] as a considerable convenience.

Reference to specific details of construction without'mentioning alternative structures is not done with intent to limit the Aclaims that follow. said claims being intended to cover all mechanical equivalents where their wording does not specifically negative such' intent.

l-laving thus described my invention, what l claim as new and desire to secure by Let- .ters Patent, is f l.. In a gas engine primer, in combination with a cylinder', a plunger therefor, the cylinder provided with a port, means'for closing the port and means for mounting the port closing means in the plunger so as to be movable therein and means for locking the plunger, said port closing means adaptl ed to seat before the lock takes eifect in the operation of the plunger.
