PRIMING MEANS FOR INTERNAL-COMBUSTION 11,26)? ,iidd.
Specification of Letters Patent.
Application filed December 30, 1915; Serial noiseize.
T all whom it may concern Be it known that I, WiLLIAM B. Loxonsn.
a citizen of the United States, and a resident of Louisville. in
This invention'relates to improvements 111 priming devlces for internal combustion enginesf-one object of the invention'being to provide simple and eilicient priming means which will operate to assist in the easy starting of the engine especially in cold weather. y
A further object is to provide means for atomizing liquid "fuel with. air .directly into the manifold and in such manner as to avoid projecting the spray against the wall of the manifold and so that atomized fuel anda-ir. shall be drawn promptly into the engine cylinder. i
With these and otherobjects in View, the invention consists in certain novel features of construction and combination of parts as forth and pointed out in the hereinafter set claims. v In the accompanying drawings, Figure-1 is a view partly in elevation and partly in section showing one embodiment of my invention, and Fig. 2 is a similar view showing a modified construction,
1 represents the-intake manifold ofa'n internal combustion engine; 2 the intake pipe provided with a suitable throttle valve 3 and 4 is a diagr'ammatical representation ofa carbureter.
A comparatively small reservoir 5 may be supported by the intake pipe and for this purpose, the reservoir is provided with a threaded nipple 6 which passes through the wall of the pipe 2. The reservoir is intend.
ed to contain gasolene for priming purposes and may be supplied with gasolene from any convenient source of supply, through a pipe 7. A valve 8 is provided for the pipe 7 and may conveniently consist of a rod passing through the cover of the reservoir and formed at its lower end to close the inlet of the gasolene pipe 7,'-said valve being normally retained upon its seat by the action of a spring '9. The upper end of the valve 1 the county of Jefferson and State ofKentucky, have invented oer-- rod is made with agroove 10 to receive one arm of a bell-crank 11' pivotally mounted 1 Patented n ed,- rain;
upon the cover of the reservoir, and to the other arm of this bell crank, one end of a wire 12 is atta'ched,'-the other -,end' of said wire being located within convenient reach of the operator toenable him to manipulate the valve 8 when it becomes necessary to replenish the suppy of gasolene. in theresen voir5.
A tube 13 passes through and. is supported by the nipple '6 and is formed at its inner end with an upwardly projecting member 14 which passes tliroiugh; the cover of the reservoir 5 and is open at its upper end;
The free end of the tube 13 is located within the pipe 2 and is made witha nozzle outlet 15 disposed to discharge in line with the bore of said pipe and in a direction toward the intake manifold 1. Another and smaller tube 16- passes through the nipple 6 and its open beveled end 17 projects across the nozzle. outlet 15 of the pipe 13, within the intake pipe'2. The other end of the tube 16 depends within the reservoir 5 as at 18) so as to be immersed in the gasolene therein and is provided at a point somewhat below the normal level of the gasolene, with a; small hole 19. I
When. the reseri'oir is empty, the upper end ofthe'air pipe l3 -l4'will be closed by a valve 20. This mlve is carried by a rod 21 passing through the upright member 14: of the air tube and providedat its lower end. with a float 22. When the reservoir issupplied with gasolene, as indicated in the drawing, the float will cause the valve 20 to rise and thus apen the member 14- of the air pipe to the atmosphere.
In the construction shown in Fig. '2 the 3 reservoir may be provided with a removable cover 25 and the air tube made to terminate within or at the upper end of the reservoir' g' so as to be open to the atmosphere when the cover 25 has been remqy When the I engine is. v.
being started by cranking in the usual way, or by means of a ments afford means for supplying a rich ex plosive mixture, thus making starting very easy.-
-A very rich mixture of gasolene and air. w1ll|be provided until, the level of the gasolene descends below the hole 19' in the member 18, of the gasolene' tube 16. When said hole 19 becomes exposed, air will enter and thus the richness of the mixture will be re -duced,' 'thu's avoiding too, rich a mixture after the engine has' been started and speed- During the operation -of the form of the device shown in Fig.2,the cover 25 will, of
- course be removed, but after the engine shall has been started. Should it be found inconvenient to attach my improvement to the intake pipe.'2, the same may be attached didectly to themanifold, at 23 orQ l, Fig. 2, and so disposedthat the spray will be pro jected as indicated; by the arrows.
Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is: t
1. The combination with the intake of an internal combustion engine, of priming means comprising a liquid'fuel reservoir, a liquid fuel tube. projecting from said reservoir so as ,to' discharge into said intake, and an airtube having a nozzle opening adjacent to the discharge end of the liquid fuel tube, whereby an atomizer is formed, said liquidfuel tube having a hole somewhat below thenormal liquid fuel level in the reservoir.
2. The combination with the intake of an internal-combustion engine, of aliquid fuel reservoir having-a nipple to enter the intake, two tubes extending through said nipple and having their discharge ends arranged mouse in permanent and unobstructed atomizer relation to each other, the other end of one of said tubes adapted to enter liquid fuel in the reservoir, and the other end of the other tube being open to the atmosphere.
3. In priming means for an internal combustion engine, the combination with a liquid fuel reservoir, a liquid fuel tube having one end terminating within said reservoir and having its discharge end projecting from said reservoir, an air pipe open at one end to the atmosphere and having a nozzle outlet at its other end disposed at right angles to the discharge end of the liquid fuel tube, forming a permanent, unobstructed atomizer, and means for temporarily closing the inlet end of the air tube.
4:. In a priming device for an internal combustion engine, the combination with a liquid fuel. reservoir adapted for attachment to the intake of the engine, of a liquid fuel tube and an air tube projecting from said reservoir and having their discharge ends arranged in atomizer relation to each other, the inlet end of the air tube being open to the atmosphere, a valve for closing the inlet end of the air tube, and a float within said reservoir and connected with said valve.
5. In priming means for internal combustion engines, the combination with a liquid fuel reservoir adapted for attachment to the intake of the engine, an inlet pipe for liquid fuel communicating with said reservoir, a spring actuated valve for said inlet pipe, manually operable means for opening said valve, a liquid fuel tube and an air tube projecting from the reservoir and having their discharge ends arranged in atomizer relation to each other, the inlet end of the air tube being open to the atmosphere, a valve for closing said air tube and a float in the reservoir and connected with said valve.
In testimony whereof I have signed this specification in the presence of two subscrib v ing witnesses. I
