GAS-MANUFACTURING APPARATUS# Patented March 5, 1907.

Application filed May 26, 1906. Serial No. 318,826.

To (J1/ZZ whom it may concern:

Be' it known that I, JACOB J. BUsEivBENz', a citizen of the United States, residing at Chicago, in the countyof Cook and State of Illinois, have invented a new and useful Gas- Manufacturing Apparatus, of which ythe following is a specification. l

My invention relates particularly `to means for injecting air and volatile liquid fuel, such as gasolene or alcohol, in atom'izing relation* ship into the mixer-chamber or' gas-manufacturing apparatus. j j

My primary object is to provide an injecting devicek adapted for use in apparatus for the manufacture of fixed gas from the vola# tile liquid fuels, such as the hydrocarbon oils and alcohol, without the employment of heat in the manufacturing process. j

The invention is illustrated in its preferred embodiment in the accompanying drawing, which shows a sectional view of thedevice. l In the drawing, A represents a fragment .of one wall of a mixer-chamber, and A my improved atomizing and injectingdevice ap- The devlce A comprises a casing a, connected by cap-screws a with the chamber A; an injector-tube a2, having its innerend extending through a central opening in the inner end `wall a3 of the casing and held by nuts a, screwed onto the tube and clamping said wall between them; a gatevalve a5, controlling the injector-tube 'and having a stem a projecting through a lateral wall of the casing a; a nozzle a7, connected with the outer end of the casing a and having its pointentering theinjector-tube a?, and an air-conduit es, connected with the upper side of the casing and having communi-y f cation with the external atmosphere.

- to receive the cap-screws a.

The wall of the mixer-chamber A, with which the casing a is connected, isprovided with a relatively large opening a, which is covered bythe inner end ofthe casing. The casing is flanged externally at its inner end The threaded inner end ofthe injector-tube (L2 passes reelv through an opening (1,1 with which the wall i 'a3 of the casing is provided. The casing of ying-wall by cap-screws (L14.

Athe valve (L5 has a lateral extension a, which is received by a stufling-box a", provided with a flange a and connected with the cas- The body of the stuffing-box asses freely through an opening (1,15 in the ywa 1 of thecasing. The details of the valve a5 need not be explained, as the valve is of common construction. 'Ihe nozzle a7 comprises a tubular member al, having its inner end projecting through an opening in the outer end of the casing'a, the member a, which is connected by cap-screws as with the end of the casing; a tubular member al", extending within the member al and having threaded connection (11,20 with said member; an annular nut a, encircling the shank of the member al and having its inner end provided with internal threads engaging with member (116; a gasket (L22, confined between an internal shoulder of the member a21 and the outer end of the member am; a packingring (L23, having screw connection with the member am; a tubular member a, having screw connection with the member aw; a gasket c25, interposed between the member (1,24 and the member @23; a tubular member a2, having screw connection ai" with the mem- 'ber au; a pipe (L28, having screw connection with the membera'l, and a pipe a2", .having screw connection with a lateral opening in the member al and communicating with an annular chamber c3 between the member (L1Q and the member al".

The inner end of the tubular member am projects slightly into the vouter end of the injector-tube (L2, and the tube a2 is provided near its outer end with a set ci openings (1,31,

with a set of openings (1,32. a2 has a bore which tapers from its outer end to aA point just inthe rear ofV the opening (132 as indicated at a, and said bore then expands, as indicated atea, to a point just inside ofthe opening 0,32. The annular passage a3 between the internal surface ofthe memher a converges at the point of the nozzle, as indicated at (L35. The member al has a tapering point e36, which projects into the tapering bore at the inner end of the member a. successively-reduced diameters as the point ofthe memli er is approached, where a minute oriiice c is provided.. The point of the member a2 pro`ects slightly beyond the point of the mem er a1". 'The member (L19 is adjustable with relation tothe member a,16 to z vary the tapering annular orifice at (1,35, and

al being provided with an external flange` external threads on the outer ends of the and at a greater distance iromits outer end j The injector-tube The member a2 has a bore which is of ber al@ `and the external surface of the memroo the member a2 is adjustable .with relation to ithe member a to still further vary the ori- The conduit a8 is provided at its lower end with an external ange which is connected with the top of the casing a by cap-screws a. The casing is provided with a drainpipe a. l

In the operation of the device oil under pressure is introduced through the pipe t28 and internal nozzle a2, and air under pressure is introduced through the pipe a2 and the annular passage a3, the streams meeting at the tip of the nozzle in such relation as to thoroughly vaporizeor atomize the oil. The jet issuing from the nozzle into the injectortube a2 draws in air from the external atmosphere through the assages ai, and the augmented stream raws in additional air through,the passages a, the mixed a-ir and vapor in proportions suitable to form a fixed gas then passing through the injector-tube into the mixer-chamber, it being assumed that the valve a5 is open. In ractice the mixer-chamber is connected wit a gasometer which controls valves regulating the passage of oil and air through the pi es (1,28 and a2 andthe intake of air through t e conduit as. The device renders practicable the manufacture of gas from a volatile hydrocarbon oil or from alcohol without the employment of heat. In practice I subject the oil passing through the pipe L28 and the air passing through the pipe 0,29 to a common pressure controlled by a pressure-reducing valve, the source of comdpressed air being a tank containing air un er high pressure.

. It will be noted that the intermediate tubular member al has a straight reduced bore at its point, and the interior tubular member a26 has a non-tapering point portion entered in said bore; also, the outer end of the member a projects beyond rthe nut @23, so as tof.

facilitate adjustment when the nut a is disconnected and the internal nozzle member a2 is withdrawn. From this description it will be at once understood that the size of the annular passage at @35 may be readily regulated.

I have described my invention in .detail for clearness of understanding only.
