MIXING-AND VAPORIZING DEVICE FOR MOTORS- A SPECIFICATION forming part of Letters Patent No. 761,192, dated May 31, 1904.

Application filed October 16, 1901. $erial No. 78,783. (No model.)

To all whom it may concern.-

Beit known that 1, JAMES E. BEAN, residing .at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Mixing and Vaporizing Devices for Motors, of which the follow1ng 1s a description, reference being had to the accompanying drawings, which are a a part of this specification.

My invention has relation to improvements in mixing and vaporizing devices for motors, more especially, although not necessarily, for

, gasolene-motors.

The primary object had in view is to provide a simple construction wherein the pump ordinarily used for sucking the gasolene or other vapor-gas liquid from a tank is entirely dispensed with'and a simple mechanism employed in lieu thereof, which shall'be capable of drawing the liquid from the tank and conducting said liquid to the mixing portion of the device, there to be mixed with and atomized by the inflowing air.

A further object resides in providing a simple construction wherein the supply of gasolene may be readily controlled and set to .feed a desired quantity of liquid into the mixinafter more fully set forth;

In the accompanying drawings, Figure 1 is a longitudinal sectional view of my improvements. Fig. 2 is a plan view of the parts above the tank. Fig. 3 is an end View of Fig.

2, andFig. 4 is an enlarged sectional view of the oil-feeding device.

Referring to the drawings, the numeral 4 indicates a tank for containing the gasolene or other vapor-gas-producing liquid. In the scale, as clearly shown in the drawings.

side of said plate.

extends for a desired distance downwardly in the tank, preferably to near the bottom of said tank. Within the coupling 9 is formed a valve-seat 11, against whiehan upwardlyopening valve 12 is seated, said Valve provided with a depending guide-stem 13.

Extending across the interior of pipe 7 and communicating with the nipple 8 is a tube 14. This tube is provided at diametrically opposite points with openings 15 15. If desired,

only one opening 50 may be provided and successful results obtained. Rotatably fitting in the tube 14 is a plug 16, said plug being tubular from its lower end upwardly for a desired distance to form a channel 17 The upper end of this channel is intersected by a transverse opening 18. The plug extends outwardly from the upper surface of the pipe and has secured to its upper end an index arm 19, which is adapted to work over the face of a segmental plate 20, said plate provided upon its upper face with a' graduated The end of the arm 19 is extended beyond the outer edge of the segmental plate and is bent around said outer edge and then upwardly, so that its extremity will contact with the under This contacting extremity of the arm on the under side of the plate works over a series of indented marks 21, as shown by dotted lines in Fig. 2, said marks being graduated to conform to the scale-marks on the upper side of the plate and serve as a rack to hold the arm at adjusted position.- Secured to the end of the pipe 7 is a coupling 22. This coupling may be secured in any desirable manner; but I prefer to connect it in the manner shown in the drawings, wherein the end of the pipe 7 is shown as having exteriorly threaded thereon a collar 23, said collar provided at its outer end with a shoulder 24. A connecting band or ring 25 surrounds the joint between the pipe and coupling, and one end of this band or ring is provided with a shoulder 26, which engages the shoulder 24E of the collar. The opposite end of said ring or band is provided with female threads which engage male threads on the end of the coupling. This particular form of connection provides a means for ready adjustment in case the fittings are not perfect.

Within the coupling 22 is a partition 27, the horizontal portion of said partition provided with an opening forming a valve-seat 28. Normally closing this opening is a valve 29,

which is provided with an upwardly-extending guide-stem 30, said stem fitted and guided in a tubular extension 31. The guide-stem is surrounded by a' coiled spring 82, which is confined between the upper side of the valve and the under side of the tubular extension. Connected to the outer end of the coupling 22 is a pipe '33, which connects with and conducts the mixture to the cylinder (not shown) of the engine and which cylinder may be of any of the usual and well-known forms of constr'ucti'on. I

In the operation of the invention the plug 16 is turned so that its opening 18 is brought intoregistration with the openings 15 15 of thetube 1 1. If the maximum amount of gasolene to which the device is capable of feeding is desired, theplug is turned so that the opening 18 is in full'registratio'n with the openings 15, or if it, is desired to feed a less quantityof gasolene the plug is turned so that there will be only a partial registration of said openings.

The graduated scale on the segmental plate determines the extent the handle 19 is required to be turned in order'to provide for the feed of a given amount of gasolene, and

when the handle is turned to the proper position it is held stationary in that position until it desired to change the feed. It is obvious that instead of the openings 18 and 15 extending through both sides of the plug 16 and tube 14c, respectively, they may extend through 'one side thereof only and such openings arranged to register at "any point where a suction would be produced therethrough.

When the engine mechanism is started, the

suction created by the piston on its reciprocation in one direction will overcome the tension' of the spring 32 and raise the valve 29. This suction will also draw in air through the open end 'of the pipe 7, and the air so drawn in andi-ushing past the tube l4will cause the gasolene to be drawn up in the'tube 10, the ascending gasolene raising the check-valve 12,

and flowing above said valve into the passage 17 of the plug 16, thence through the opening 18 of said plug, and'out of the openings 15 of the tube 14 and into the pipe 7. The checkvalve 12 of course serves to prevent the backflow of the gasolene. The air and gasolene now commingle in'the pipe 7, the air having the effect of atomizing and vaporizing the gasolene. The mixture now flows into the coupling 22, thence through the valve-opening 28 into pipe 83, and finally through said pipe to the cylinder of the engine.

From the construction above described it will be seen that I provide a simple means for drawing the gasolene from the tank without the necessity of employing a suction-pump,

. as ordinarily used, and I also provide a most 'efficient means for mixing gasolene and air and atomizing and vaporizing the gasolene, together with provision 'for accurately regulating the amount of gasolene drawn from the tank.

The small holes 15 15 and 18 are quite liable to become clogged up with dirt, and there by impair the working of the device. It is to guard against this that I provide for the removability of the plug 16. In order to remove said plug, all that is necessary to be done is to turn the handle 19 until the extremity thereof which is beneath the plate 20 has passed either end of said plate. The plug can then be readily removed and the passage 17 and the opening 18 thereofcleaned without difficulty, When this plug is thus removed, it is also evident that access may be readily obtained to the holes 15 by means of a wire or other device inserted through the end of the pipe 7 andthrough said holes 15.

The extremity of the handle 19,which bears against the under side of the plate 20,.not only forms a means icy-engagement with the indentations 21 for holding the handle in adjusted position, but said end of .the handle also prevents the plug frombeing removed until the handle is turned sufliciently far in either direction for the extremity thereof to clear either end of the plate 20. I would also call attention to the fact that by providing the coupling 9 at the upper end of the tube 10, said coupling having a threaded connection with the nipple 8, the distance the tube .10 extendsinto the tank 1 may be readily regulated. I would furthermore call attention to the fact that I- prefer to provide in the outer end of the pipe 7 a thin partition 34, the rear edge of said partition almost touching the tube .14; and being in line withthe outer opening 15 of said tube. Experience has demonstrated that by the employment of this partition the capacity of the device for drawing the gasolene upwardly into the pipe? is greatly augmented.
