CARBURETER.

SPECIFICATION forming part of Letters Patent No. 593,284, dated November 9, 1897.

Application filed April Y, 1896. Serial No.586,57l. (No model.)

To a/ZZ whom it may concern.-

Be it known that I, FRED W. SPACKE, a citizen of the United States, residing at Indianapolis, inthe county of Marion and State of Indiana,` have invented a new and useful Oarbureter, of which the following is a specication.

My invention relates to an improved carbureter for use in connection with gas-engines.

The object of my invention is to produce a device which may be easily attached to any formof gas-engine and which will supply said engine with an oil-vapor or gas.

The accompanying drawings illustrate my invention.

Figure 1 is a central longitudinal section of the carburetor. Fig. 2 is a view of the brush used therein.

In the drawings, 6 indicates a hollow cylindrical open-ended body provided with a suitable base 7, which is adapted to be bolted to the floor or to the engine-bed. A cap 8 is adapted to close one end of body 6, and said cap is provided with a central hollow boss 9, which carries at its outer end a bearing 10. A cap 11 is adapted to close the opposite end of body 6 and secured to or formed integral with said cap is a vertical oil-receiving chant ber 12. Said chamber 12 is preferably open at both ends, and its lower end is closed by a cap 13, which screws therein and is provided on its inner face with a pin 14, which projects a short distance into said chamber. A cap 15 is adapted to close the top end of chamber 12, and entering into the top of said cap is a suitable oil-supply pipe 16, provided with a valve 1'7. Cap 15 is provided with a central opening,into the lower end of which is screwed a short plug 18, provided with a passage 19, which extends therethrough and leads into chamber 12. The lower end of passage 19 is enlarged, so as to form a valve-seat 2O therein, said enlarged portion also acting as a guide for the upper end of a valvepin 21, which is adapted to slide vertically therein. The upper end of said valve-pin is formed so as to iit into valve-seat 2O and to thereby close the opening between chamber 12 and the oil-supply pipe, and the lower end of said pin is provided with a head which rests loosely upon the upper end of a float'22, mounted in chamber 12 and adapted to iioat in any liquid which may be introduced into said chamber.

A series of passages 23 is formed in cap 11 and forms a communication between the interior of body 6 and the interior of chamber 12.

A bearing 24 is formed in the inner surface of cap 11 opposite bearing 10, and mounted in said bearings is a shaft 25, on which is mounted a brush 26, said brush being preferably formed of bristles and substantially flllin g the interior of body 6 and being adapted to be rotated therein. The end of shaft 25 passes out through bearing 10 and the stuffing-box carried thereby, and secured to the said extended end is a pulley 27 by means of which the shaft and brush may be rotated.

Opening into the side of chamber 12 near the top thereof is an air-supply pipe 2S. The opening in boss 9 is considerably larger than shaft 25, and leading into said opening is a pipe 29, which leads to the gas valve or valves of the engine.

Pipe 29 of the carburetor is connected with the gas-inlet valve or valves of the engine, and a belt is passed around pulley 27 and any suitable shaft mounted on the engineframe.

The operation is as follows: Supposing chamber 12 and body 6 to contain no oil, float 22 then rest-s upon the upper end of pin 14, which is made sufficiently long, so that when the doat is in the position described the upper end of valve-pin 21 extends some distance into the lower end of passage 19. Valve-pin 21 rests upon the upper end of the iioat, so that when the float is in the position described the upper end of said pin is withdrawn from valve-seat 20 and communication is established between chamber 12 and the oil-supply. Valve 17 being open, the oil enters through pipe 16 through said valve, the upper end of cap 15, through passage 9 of plug 1S,and down into chamber, 12, the said oil continuing to flow until the oil, passing through the lower openings 23 into body 6, reaches the level indicated in Fig. 2. The oil as it rises carries float 22 and valve-pin 21 upward until the upper end of said pin rests in seat 20 and thereby shuts off the supply of oil. The belt being connected with some rotating part of the engine, brush 26 is rotated in body 6, some IOO of the oil in the bottom of said body clinging to bristles or wires of said brush and being carried into the upper part of said body thereby. By the action of the piston of the engine the air is drawn through chamber l2, passages 23, body 6, and out throughl pipe 29 in to the engine. As the said airpasses through the body 6 it 'passes through the brush and around the bristles thereof and thereby becomes laden with the oil-vapor. As the brush rotates and the air carries offy a portion of the oil the level of the oil in body 6 is lowered, and as soon as this happens float 22 drops, thus allowing the upper end of valve-pin2l to leave seat 20, and a sufficient amount of oil is allowed t0 enter to maintain the level. The entrance of the oil is entirely ycontrolled by the depth of oil in the body 6, and it is therefore possible to keep said depth uniform. It has been found preferable to make brush 26 of bristles or other slightly absorbent ma terial, the oil soaking into the said bristles and therefore carrying a greater portion of oil into the upper part of lbody 6, where it can be evaporated by the air. By passing heated air through body 6 a much more permanent gas is formed and said gas is much more easily exploded.

I claim as my inventionl. In a carbureter, having means for agitating the carbureting fluid, the combination with the hollow chamber having an oil-supply pipe leading thereto, a float mounted in said chamber, a valve-seat formed in the upper end of said chamber at the mouth of the oil-pipe and provided with a downwardly-extending guide, a valve-pin mounted so as to move in said guide, the upper end of said pin formed to lit into the valve-seat and the lower end of said pin resting loosely upon the upper end of the float, and means for preventing said pin from dropping out of the guide, substantially as described.

2. In a carbureter, having means for agitatin g the carbureting fluid, the combination with the hollow chamber l2, a cap 11 for the upper end thereof, said cap being connected with an oil-supply pipe which leads into the chamber, a plug 1S carried by said cap at the mouth of the supply-pipe, apassage 19 formed through said plug and provided with a valveseat 20, a ioat mounted in the chamber below the plug, a valve-pin mountedso as to move in the lower end of passage 19, the upper end of said pin formed so as to fit into seat '2O and the lower end of said pin adapted to rest loosely upon the float, and means mounted below the oat for engaging said iioat, whereby the said float cannot drop low enough to allow the valve-pin to drop out of the lower end of passage 19.

3. The combination of a hollow, open-ended body, a cap adapted to close one end thereof and provided with a bearing for a shaft, a shaft mounted therein, a brush mounted on said shaft and adapted to be rotated in said hollow body, a cap for the opposite end of said body, a chamber carried by said cap, a passage forming a communication between said chamber and the interior of said hollow body, an oil-supply pipe leading into said chamber, means mounted in said chamber for controlling the supply of oil, an air-inlet leading into the interior of the hollow body, and an airoutlet leading therefrom, substantially as described.

4. In a carbureter, the combination of the hollow body, a cap S for one end thereof, a cap 11 for the other end thereof, a hollow boss carried by cap 8, a bearingcarried by the outer end of said boss, a bearing formed in cap ll, a shaft mounted in said bearings and extending through the first-mentioned bearing, a brush mounted on said shaft inside the hollow body, a chamber carried by cap ll, a series of passages forming a communication between said chamber and the interior of the hollow body, an oil-supply pipe leading into the upper end of saidl chamber, a plug secured at the mouth of said pipe and having a passage formed therethrough, a valve-seat formed near the upper end of said passage, a float mounted in said chamber, avalve-pin mounted in the lower end of the passage in the plug, the upper end of said pin formed so as to fit into the valve-seat and the lower end of said pin resting upon the upper end ot' the ioat, all combined and arranged to coperate substantially as and for the purpose specified.
