CARIBURETER.

Specification of Letters Iatent.

Patented Apr. 3, 1917.

Uriginal application filed August 29, 1907, Serial No. 390,652. Divided and this application filed. July 16,

- 1912. Serial No. 709,747. 7

To all whom it may concern:

Be it known that I, RUSSELL HUFF, a citizen of the United States, and resident of Detroit, Wayne county, State of Michiing drawing, in which- Figure l is a vertical section through a carbureter embodying the invention;

Fig. 2 is a section taken at right angles to the section of Fig. 1 andembodying a slight modification;

Fig. .3 is a plan view partly in section on the line 22 of Fig. 1, and

Fig. 4 is a section on the line 44 of Fig. 1.

- Referring to the drawing, 1 indicates the gasolene filter well and 2 the float chamber. These parts are of ordinary construction and need not be described in detail. It will be understood that the gasolene passes from the float chamber directly into the nozzle 3, and that it is drawn from the nozzle periodically by the suction created in the cylinders by the working of the pistons therein.

Referring to the drawing, 4 indicates the primary air intake (shown more clearly in Patent 1,095,326) which is open at its outer end to the atmosphere and communicates at its inner end with a chamber 5 surrounding the gasolene nozzle 3. From the chamber 5, a tube 6, concentric with the nozzle and surrounding the same leads upward into the mixing chamber 7. The upper portion of the tube 6 is flared outwardly preferably above the outlet of the nozzle 3. It will be understood that at each cycle of operations of the engine the gasolene is drawn from jacket of the engine cylinder and conducted into the water-jacket .8 through the inlet 9. After passing through the water-jacket the water is conducted diametrically across the mixing chamber in the'tube 10 to an outlet 11. As shown, the tube 10 is formed with an enlargement 12 having a downwardly depending corrugated surface directly over the gasolene nozzle 3. This provides an enlarged heated surface against which the mixture of gasolene and air is projected, which greatly facilitates the vaporizing of the gasolene and increases the eiiiciency of the carbureter. The mixture is conducted from the upper end of the mixing chamber through suitable conduits to the cylinder or cylinders of the engine.

In Fig. 2, the outlet from the waterjacket 8 is through a tube 10 extending ;-diametrically across the mixing chamber directly over the gasolene nozzle. This tube 10 is preferably threaded to increase its surface and the gasolene is sprayed toward it. The tube thus acts as a panel to intersect any unvaporized gasolene and hold it in a current of air, and it also serves to vaporize the gasolene, due to its heated state.-

Within the mixing chamber is'a throttle valve 13 which is adapted to completely close the direct passage through the mixing cham-- passing to the motor which will permit the motor to idle or run at a minimum speed.

In the present instance I provide a by-- pass which is formed in the walls of the mixing chamber and which is accessible from the outside of the carbureter and adjustable to vary the minimum supply of mixture.

' 14, 15 indicate two bores or passages which intersect and which extend entirely through the wall of the mixing chamber and through solid metal extending across the watenjacket. One of these tubes is closed at the outside by a plug 16 while the other is closed by an adjustable valve 17, the said valve being adapted to close the by-pass 14, 15, or to leave same open to any desired degree. The valve 17 is provided with a lock nut 18 for holding the valve in any desired adjustment. lit will be obvious that the by-pass can be adjusted with ease from the outside and also that it can be readily cleaned by removing the plug 16 and the valve 17.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a carbureter for hydrocarbon engines, the combination of a mixing chamber having a hot water tube extending thereacross and formed integral with the walls of the chamber, a throttle valve arranged in said chamber and adapted to control the flow of mixture therethrough, and a by-pass formed in the wall of said chamber and providing a restricted passage for mixture when the throttle va'lveisclosed.

2. In a carbureter for hydrocarbon engines, the combination with a mixingchamber, of a valve therein, and a by-pass around said valve, said by-pass comprising two; intersecting passages through the wall of the mixing chamber, one of said passages being provided with a removable plug and the other being provided with a removable and adjustable valve, whereby the by-pass may be controlled and readily cleaned.

3. In a carbureter for hydrocarbon engines the combination with the mixing chamber of a gasolene nozzle discharging therein, an air intake for said chamber, a water-jacket for said chamber, a valve adapted to close the passage through said chamber, and a bypass around sa1d valve comprising two intersecting passages extending through from the interior of the mixing chamber to the exterior of the waterjacket, a removable plug in one of said passages, and an adjustable and removable valve in the other opening, for the purpose set forth.

4. A carbureter for hydrocarbon engines comprising a mixing chamber and a throttle valve therein, the walls of said chamber having intersecting openings affording a bypass around said throttle valve.

5. A carburetor for hydrocarbon engines comprising a mixing chamber and a throttle valve therein, the walls of said chamber having intersecting openings affording a bypass around said throttle valve, and removable closing means in the outer ends of said openings whereby the openings may be reached for cleaning.

6. In a carbureter for hydrocarbon motors, the combination with a mixing chamber comprising double cylindrical walls forming a water-jacket around the chamber, inlet and outlet .pipes for said water-jacket, a throttle valve in said chamber, a metal filling between said walls adjacent said throttle valve, said metal filling having a by-pass formed therein around said valve.

In testimony whereof I aflix my signature in the presence of two witnesses.

. RUSSELL HUFF.
