FREDERICK BARTHEL, OF DETROIT, MICHIGAN, ASSIGNOR TO FREDERICK E. WADSWORTH, OF DETROIT, MICHIGAN.
CARBURETER.
Specification of Letters Patent.
Application filed January 7, 1911. Serial No. 601,263.
To all whom it may concern:
Be it known that I, FREDERICK BARTHEL, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Carburetors, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to carbureters and an object of my improvement is to provide an improved carbureter, which will earburet the air as it passes into the combustion chamber of a two cycle internal combustion engine.
In the previous state of the art, carbureters have been constructed to deliver the hydrocarbon to the air as it passes from the atmosphere to an internal combustion engine, the spraying action being due to the current of air passing the delivery nozzle. And carbureters have been constructed to deliver the hydrocarbon to the air as it passes to the combustion chamber of a two cycle internal combustion engine. This latter kind has been designed to be actuated by a difference of pressure between the reservoir from which the hydrocarbon is drawn and the delivery nozzle. this diflerence of pressure being attained by connecting said reservoir with a part of the engine remote from that at which the delivery nozzle is located, so that the reservoir shall be connected with a portion of the delivery apparatus of the engine in which the air is at a greater pressure than it is at the point at which the delivery nozzle is located.
In my device, I arrange that the hydro. carbon shall be delivered to a two cycle engine by the action of the current of air pass ing the delivery nozzle, as in the first kind of apparatus above described. I therefore place the delivery nozzle at a point where the passing current of air shall spray the hydrocarbon therefrom and I connect the reservoir with a point of the air delivery apparatus of the engine closely adjacent to said delivery nozzle so that the pressure in the reservoir and at the delivery nozzle shall be practically the same, except for the spraying action of the assing current of air. I accomplish this 0 ject in the device illustrated in the accompanying drawings, which,
Figure 1, is a sectional elevation of a two cycle gas-engine having an apparatus embodying my invention attached thereto; said apparatus being partly in section on the same plane as the engine. Fig. 2, is a de tail view of the apparatus embodying my invention separate from the engine, the reservoir and immediately adjacent parts being broken away to show the internal construction. Fig. 3, is a plan view of said apparatus.
A, is the cylinder, and B the crank case of a two cycle internal combustion engine; the cylinder opens into the crank case and the latter serves as a compression chamber as in the usual construction of such engines.
S, is the intake .valve to the crankcase B.
'F, is the bypass for the air.
G, is the port through which the air is discharged from the crank case B through the passage, or by-pass, F in the combustion chamber.
E 0:, is the exhaust port, E, the piston, D, the connecting rod, and C, the crank of the engine.
N, is a reservoir for the liquid hydrocarbon.
0, is the supply pipe to the reservoir N.
T, is a check valve controlling the port between the reservoir N and the supply pipe 0 and automatically opening toward said reservoir.
n, is a float and t, is a ball or valve on a stem depending from. the center of the float n, the same acting to maintain an approxi mately constant level in the reservoir N, in the usual way.
X, is a casting, consisting of a horizontal cylindrical portion I, and a portion Y extending downward toward one end of the portion I.
h, is a screw threaded nipple formed on the end of the portion I.
y, is a screw threaded nipple extending laterally from the portion Y. a
The portion I is bored in from one end to form a comparatively large opening or bore, i, therein extending about two-thirds of the way through from end to end. .From the rear end of the bore 2' in the portion I an aperture extends upward which is internally screw threaded.
,P, indicate a series of pipes, one. endz'bein; fitted into the lateral aperture eonnnnnieating with. the bore and the other end of said pipes ('UllltiHLltittt'lllQ with the reservoir N above the level of the fluid thereinfthus formingan open connection bet weentsaid reservoir and bore.
llxtendine' in from the opposite end of the cylindrical portion l to that 'from which the bore 1' extends, is a coaxial cylindrical aperture ll. There is a partition K left between the inner ends ot the aperture'l. and bore i. sinall aperture coaxial with the apertures and l, i drilled through the partition K, and into this aperture is tightly fitted a small pipe J which extends through and out of the end of the bore leaving a space between its outer wall and tlieinner wall of the bore 1'.
is a needle valve adapted to control the opening to the pipe J. The nipple 7 is screwed into a screw threaded aperture in the reservoir N below the level of the fluid therein and the nipple h is screwed into an aperture It in the engine'wall, the end j ot the pipe J extending into the port G. The pipes are then coi'inected to form a cominunicatioii between the bore 7'. and the interior of the reservoir N, as above described.
There. is an aperture 7/ formed vertically through the portion Y and communicating with the aperture I) and there is an aperture drilled coaxial with the nipple Y t ltilii the outer end of said nipple and coininiinieating with the aperture 7). The lower end of the aperture 7) is closed by a plug, as
' indicated.
The operation of the above described device is as totlows:--lhe bore 6 communicatin; with the reservoir .1 throughttihc pipes l and with the engine at a point. adjacent to the nozzl keeps the pressure in said reservoir the same as at the end oft-the pipe J and the air rushing through the ihv-pasrs l and through the port (i acts to spray the hydrocarbon troin the end j, of the pipe in the usual way.
It will be seen that the device ma be ea ily and cheaply constructed. as there is but one casting X to be made which may be drilled into to form the varioi' s chamhers and api'irtures and may be readily eon net-ted with the usual cup or reservoir N and crewed into tin-aperture in the wallof the engine.
\Vhen the piston lfi ascends a partial vacliitlli is formed in the crank chamber l3, hjvpa s t. bore 7'. pipe l. and the reservoir N ahoie the liquid ther in. and a supply of iivdrorarbon is drawn through the pipe to .--u; pty an v sli;1'ht, deficiency that may be th nii it there i sulli ient liquid in the rewrroir the valve cheats the. apertur through the upply pipe and prevents any t'urther intlow at tiuid.
t agc. N, the tiout n, will he raised until The amountof hydrocarbon delivered .niay be regulated in the usual way by the needle valve M.
