To all whom it may concern:
Be it known that I, GEORGE W. SLAUGH- TER, Jr., a citizen of the United States, residing at San Augustine, in the county of San Augustine and State 01 Texas, have invented anew and useful Carbureter for Explosive- Motors, of which the following IS a specification.
This invention relates to carburetors forexplosive motors and more particularly to that ty e of carbureter arranged to enrich a body oi incoming air with a predetermined amount of liquid hydro-carbon.
'One object gt the invention is to provide an improved and simple form of carbureting valves.
Another object of the invention is to provide an improved means for more thoroughly mixing theliquid hydro-carbon and air.
A third object of the invention is to regulate the quantity of liquid hydro-carbon to be admitted, and that without reference to the condition of the atmosphere as to temperatureor barometric pressure.
The invention consists in general in a carbureting valve provided w.th a measuring chamber for the liquid hydro-carbon and an improved form of mixing chamber.
The invention further consists in certain novel details of construction, combinations of parts and improved arran 'ement theieol', hereinafter fully described, illustrated in the accompanying drawings, and specifically set forth in the claims. I
In the accompanying drawings like charactors. of reference lndicate like parts throughout the several views and Figure 1 is a vertical sectional view 01' the invention. 2 is a transverse sectional view taken through the center of the hydro-carbon valve. Fig. 3 is a top plan view with the cage and valve pro -r renioved. Fig. 4 is a detail elevation of t 1e valve.
The numeral 10 indicates the body of the valve. This valve body is provided with a threaded portion 11 arranged to receive'the end of an inlet pipe 12 which ail'ords communication .to the engine cylinder. The
valve body 10 ,is provided with a frustoconical valve seat 13 having an annular 'i groove therearound as indicated at 14.
provided with inlet ports 17, is held in this rabbeted portion. inlet end of the valve body to the top of the groove 14 is an air passage 18 the ends whereof are preferably displaced singularly with reference to the of the valve seat, as clearly shown in Pi 3. In the preferred form of the invention this air passage is spirally formed as shown in that 'li 'ure and Fig. l. The valve body is further provided with a threaded connection 19 adapted to receive a pipe leading from the hydrocarbon supply tank, the fuel being fed therefrom by either gravity or under pressure as may be found most convenient. Leading from this connection to the frusto-conical valve seat isa hydro-carhon passage 20 provided with a needle valve21 of the usual form. The valve proper comprises a frusto conical body portion 22 provided with an.
Extending from the air stem 25 runs upward through the cage 16,
and carries at the outer end a nut and Washer 26. A spring 27 is arran ed to be held between this nut and washer and the top of the cage 16, being pro erly tensioned to keep the valve tightly c osed except during the suction stroke. 1
In the operation of this device, the needle valve 21 havin been properly adjusted, the hydro-carbon tows through the assage 20 and into the annular groove 24. ow, upon the suction stroke of the engine, the valve is opened and the hydro-carbon flows down the side of the frusto-conical valve it being drawn in also directly from the assa e 20.
.At the same time air enters tiroug 1 the spirally formed passage 18 and imparts a rapid whirling motion to the body of air con tamed in the groove L4 and groove 23. Simultaneously air enters the annular passage formed by the opening'of the valve and the hydro-carbon is thus forced down and mixed,
by the combined whirling movement of the air in the groove 14 and groove 23 and the movement of the air down' -along the side of bon passage when the valve is closed.
.said valve seat wit 'terior of the body to said valve seat, said valve 'terior of the bodv to said valve seat, said.
the trusts-cone. There is thus obtained'a very thorough mixture of the hydro-carbon and air. I
l-lavin thus described the iiivention what is claime as new is z 1. In a carbureter, a valve body provided with a frusto-conical valve seat and having a hydro-carbon assage leading from the exterior of the be y to said valve seat, said valve seat being further provided with an annular groove formed therearound below the 0 ening of said passage and an air passage ironithe admission end of said valve body to said groove, and a frusto-conical valve yieldingly held in said valve seat.
2. In a carbureter, a valve body provided with a frusto-conical valve seat and having a hydro-carbon passage leading from the eX- terior of the body to said valve seat, said valve seat being further provided with an annular groove forrned therearound below the opening of said passage and an air passage from. the air admission end of said valve body to said groove, the inlet end of said air passage being angularly dis laced around the axis of reference to the outlet end, and a irusto-conical valve yieldingly held in said valve seat.
3. In a carbnreter, a valve body rovided with a frusto-conical valve seat and aving a hydro-carbon passage leading from the exseat being further provided with an annular groove formed therearound below the 0 en ing of said passage and a spirally former air passage from the air admission end of said valve body to said groove, in combination arr-filth a frusto-conical valve yieldingly held in said valve seat.
4. In a carbur'eter, a valve body provided with a frusto-conical valve seat and having a hydro-carbon passage leading from the exterior of the body to said valve seat, said valve seat being further provided with an annular groove formed therearoundbelow the opening or said passage and an air passage from the air admission end ofsaid valve body to said groove, the inlet end of said air passage being angularly displaced around the axis of said valve seat with reference to the outlet end, in combination with a-frusto-conical ,valve having an annular groove therearound arranged to position opposite said hydro -car- 5. In a carbureter, a valve body rovided wlth a frusto-conical valve seat and aving a hydro-carbon passage leading from the exvalve seat being further provided with an annular groove formed therearound below the opening of said passage and an air passage lrorn the air suinission end of said valve body to said groove, the inlet end of said air passage being an ularly displaced around the axis of said valve seat with reference to the outlet end, in combination with a frusto cdhical valve havin an annular groove therearound arranged to position opposite said hydro-carbon passage when the valve is closed, said valve further having a second annular groove therearound arranged. to post tion opposite the annular groove in lil'lGVtlV: seat when said valve is closed.
6. In a carbureter, a valve body rovided with a frusto-conical valve seat and avin'g a hydro-carbon passage leading from the exterior oi" the body to said valve seat, said valve seat being further rovided with an annular groove formed t \erearound below" the opening of said passage and a spir ally -formed air passage from the air admission end or" said valve body to said groove, and afrusto conical valve held in said valve seat provided with an annular groove therearound arranged to position opposite said hydrocarbo'n passage when. the valve is closed, said valve further having a second annular groove therearound arranged to position op osite the groove in said seat when said va ve is closed. v
7. In a carbureter, a valve body rovided with a frusto-conical valve seat and iaving'a hydro-carbon passage leading from the exterior of the body to said valve seat, said valve seat being further rovided with an annular groove formed tnerearound below the o ening of said passage and an air passage from the air admission end of said valve body to said recess, the inlet end of said air passage being angularly dis laced around the axis of said valve seat wit 1 reference to the outlet end, in combination with a frustoconical valve havin an annular greove' therearoun'd arrange to position opposite said passage when the valve is closed, said valve further having a second groove therearound arranged to position oppositesaid annular groove in the valve seat when the valve is closed, and a needle valve heldin said hydro-carbon passage to control the fiow of hydro-carbon therethrough.
' lin testimony that I claim the foregoing as my own, I have hereto aflixed my signature I in the presence of two witnesses. v
