Application filed Detober 7, 1914, Serial No. 865.530.

lie it known that l, (tinnitus ii. DIENER, a eitiaen ot' the l nited States, residing at lhiliulelphia, in the eounty of Philadelphia aial State at leimsyh'ania, have invented eertain new amt useful improvements in t'nrhureters, of which the following is a. speeilieation, retei'enee being lltttl to the ac- ,-ompan vin;, drawings.

This invention relates to improvements in earluireters, and has for its primary object to provirl'e a lleviee of this character adapted to be arranged in the exhaust pipe of an engine for heating, kerosene and other eom paratively heavy oils, whereby the expense in iilent to the operation of the engine may he reduced to a minimum.

The inventi n has. for a more partieular object toproi'ide an improved eonstruetion (if-the l'ieater body, and means fol-seeming the samein the'exhaust pipe, a earbareter .proper in eomn'innieation withthe gas passage, of the heater, and oil and water supply pipes in eonnnunication with the oarhuret- '5 mg chamber and-extending through theheater hotly whereby the same areheateil by the exhaust gasesfirom the engine.

'lhe invention has for another a,ml very important object ti'rprovide an improved "eonstrluition oi the carburetor proper, the same embodying a gasolene reservoir to contain the initial fuel supply, means for mounting said earhuretm' upon the exhaust; pipe and directing.heatotlair intothe ear bureting chamb r. a mixing valve opened by sueti'iih' upon the intake stroke of the engine piston' whereby the air is (ii-awn into the carbureting chamber. oil and water supply pipes, and a control valve tor regulating I the supply of oil and water through the earhuretiing ehamber.

The invention has i'or still another object; t generally improve and siiuplil') the oonstruetion ol' (leviees ol' the ab ve ehararter, to iuerease. their ellieieney ainl reliability in operation, and enable the same to be pro- (ha-ed at comparatively small manutaeturing ('ost.

With the above :illtl other ohjeets in view 0 as will heroine apparent as the ll(?S(.l'll)tl()ll proeeeils, the invention eonsists in rei'tain .ronstruetions, eomhinatious, and ;ll:lll,l0-

ments of the parts that i shall hereinafter fully (iescril'ie and claim. 1

l or a, full understaiuliug of the in\'en-' tion, reference is to be had to the following are integrally eonneetetl by a tube 12,

description and accompanying drawings, in which 7 Figure 1 i.' a vertical section through the earbureter showing the same ronneeted in the exhaust pipe of a gas engine; Fig. 2 is a section taken on the line of Fig. 1; Fig. 3 is a section taken on the line 33 of Fig. 1; Fig. i is a startion taken 011 the line 4 4 of Fig. 3; Fig. 5 15a seetion taken. on the line 5--:3 of Fig. 1: Fig. 6 is a sec- I .tion taken on the line (3(3' of Fig. 5; Fig. 7 is a top plan view of the liliXili; '(illtU1ll)8l'; Fig. 8 is a face view of the head of one of the needle valves.

Referring in detail to the drawings 5 and t3 designate-two seetions of the exhaust pipe of a gas engine which extend at right angles with respect to each other. One end of the horizontal seetion t) of this pipe is threaded for the eonneetion thereto of an elho\\'-joint member r. This member is formed upon its upper open end with a substantially annular outwardly projecting! flange H, thereby forming the upstai nlingz; annular shoulder t The body of the heater or minor. unheated at lth'incliules an elongated intermediate portion 11. the opposed end walls of which Below this tube the butlv 10 is contracted and formed with a eireular outlet 13 for the we haust gases. The edge of this outlet is adapted to seat upon the annular flange. 9 of the elbow joint member 7. The tube 12 is (centrally formed with a depending interiorly threaileal boss 14 in whieh the upper threal etl eml ot' a bolt 15 is adapted to beengaged. 'lhisliolt' is inserted upwardly through an opening proiiilettin the bottoin wall of the elbow 7. as elearly shown in Fig.

1. it will thus he a -iparentthat by turning the bolt Iii-the boilv lt) may be drawn down warilly into tight. engagement upon the upper end of the elbow and thereby rigidly so The bo l lti is also prri the upper end of the body may be eonneet-wl to the seetion 5 of the exhaust pipe; 'lhis nipple ineliules a polygonal shaped body portion having an outwardly projecting an- I nular flange 18 form d upon oneeiiti. This flange is adapted for engagement against the entl of the upwardly extending portion -16 screw of the body 20 and at the inner ed c of said flange or annular shoulder if) is ormed to lit within this reduced end 16 of the body. A coupling nut .50 is interiorly threaded as at -21 for engagement with the exterior threads on the body 10, and is formed upon one of its ends with an inwardly projecting annular flange 22, adopted for engagement over and upon the flange 18 on the connecting nipple 17. By threading this nut inwardly upon the upper end 16 of the body it will be apparent that the connecting member 1.7 is securely held in connection therewith. The body of the nipple 17 is also formed with a. reduced extcridrly threaded extension 23 for engagement with the threads formed upon the section of themhnust pipe. In this manner it will. be observed that the body ldmay be very easily and quickly arranged in the'exhaust pipe of the engine. In cases where the exhaust pipe is not provided with an elbow joint member,

it will, of course, be necessary to resort tosoiue slight modifications in theconnecting or attaching means for the body. As such changes will be obvious to the skilled mechanic, it will he understood that I do not desire to be limited to the precise details of construction above set forth.

The body is interiorly formed above the tubelQ with the spaced converging walls 24 which produce a gas passage 25. v he oppo site ends of this passage are open, one of said ends bein interiorly threaded for the connection of t e intake pipe 26 thereto, the

body and into the nipple 7.

The carburetor proper, shown at 28, includes a cylindrical body in which is pruvidcd a gssol-sne reservoir 29. An interior cylindrical wall 30 constitutes the outer wall of the mixing chamber proper, and is formed with a lateral extension 31 which provides ufipassugc 32 uiiording communication between the mixing chamber and one end of the gas passage 25 in the body 10. This extension 31 is=prorided with ears or flanges adapted to he scoured by means of suitable bolts 83 to thcciul of the body. The body oi. the curbureter is also formed with, a depending unnulsr boss,or extension 3 which is adopted to.bc lltt-sd with r the split col- .lsr 35 ormed upon the internisdistcpoi-lion of a saddle plate 38. This saddle pliit e is of semicircular form in cross section and is provided upon its inner face with two series of ribs 37 which extend transversely and ininternal vs vs seat 40 is formed, upon which the valve disk/41 is normally and yieldingly held by a spring 42. This spring is arranged around the valve stem 43mm] also receives within its upper end the reduced portion 45 of a cylindrical extension 44 formed u on the head or cup plate 46. A shoulder 4 is thus produced against which the upper end of the coil sprin 42 bears. The head 46 includes 0. threads portion 48 for engugement.

withthe interior threads formed upon the upper-end of the interior wall 30 of the carbureting chamber. The extension" 44' is formed with a longitudinal bore 49 in which the valve stem 43 loosely fits. The head or cap member 46 is also provided with an enlarged circular disk 50 which extends over and closes the upper end of gasolene reservoir 29. Upon the 'hexagonlll body 51 of the head 46 a suitable wrench ma be applied in order to conveniently three. the extension 48 thereof into the upper end of the mixing chamber or remove the same. Through the closure head a series of spaced openings 52 are formed which communicate with the carbureting chamber. Upon the head 46 a circular valve plate 53 is arranged which is also provided with a series of openlugs 54. This valve plate is formed with a central relatively large opening 55 thr gh which the shank of a bolt 56 extends. his bolt is threaded for engagement in the threaded socket or recess indicated at 57 which is centrally formed in the head 46. Upon the bolt between the head thereof and the valve plate 53 a washer or bushing 58 is disposed.

59 designates a leaf spring also having a central opening; (30 to receive said bolt, said spring being disposed between the head of the bolt and the bushing 58. One extremity of this leaf spring is reduced and angular-1y bent as ut (51 for engagement in u notch or recess 62 formed in the periphery of the valve plate 53. The other end of said spring is formed with a finger ling or loop 63. It will be apparent from this construction that the adjustable valve plate 53 provides means for regulating the supplementary supply of gal-.4

wardly projecting interiorly and exteriorly.

threaded nipples (ii. A similar nipple is also termed upon the vvall of the earlnireter hotly at thelower end of the gasolene reservoir 29 and extends at right angles to the first named "nipples. At each 'of these points, the body of the carburcter is formed with a passage or orifice (35 which conmiunicates at: its outer end with the bore of the nipple. The inner end of the, oriticc is redueed in diameter, as indicated at 66, to receive the needle point (38 of an adjustable valve rod (39, This rod is threaded, as at 70, for engagement with theYinterior threads upon the nipple til. The outer end oi said rod is formed with a knurled head 71. A

. nut is also threaded upon the nipple and secures one end of a leaf spring 73 tightly against the wall of a earbureterill. The. free end of the spring bears upon theperiphery oi the knurled head 71. "he end edge of the nipple til is dished or concaved to receive a packing gland 74. A gland nut 75 is thread ed upon the outer end of the nipple to tigi'htly compress the packing 74 around the valve rod and a ainst the end face of the nipple. An open-in 7t} in the bottom wall of the gasolene reservo'ti 29 atl'ords conununication between the same and one of the orilicestlfi. The reduced inner portion tit; of each orifice opens upon the valve seat 40.

flhe lowenend ol' the llt)tl ol" the carhureter at one side of the mixing valve and below the lateral extension 3] is formed with a transversely extending longitudinally tapering valve bore '77. With one side of this valve hore and-adjacent theoppositcends thereof the obliquely extending passages 78 communicate. the respective passages counect-ing said bore with he diai-nctrically opposed supply oritiees (3 5..

A not St; is threaded upon tllt l'ttllltt'ti end Ht otthe valve member '(J and betvveen said not and the wall of the mixer a coil spring l" is arranged upon the cylindrical extension so i the valve member. This spring: acts to yield ingly hold the valve member against longb tudinal shifting movement; in the bore 77 so that the ports 82 are properly disposed for registration \vith'the passages 78 and open lugs 83 when said valve member is rotated. The opposite end of-the valve member is formed witlra suitable linger piece no whereby the same may be conveniently turned to the desired position. The end face of each of the heads 71 on the valve rod til) are provided with a circularly arranged series of numerals, from U to 5), whereby the approximate quantity of fluid flowing through' each of theorifices 65 to the. carhureting chamber may be ascertained by the operator. The valve rods are rotated until the desired numeral thereon is disposed immediately below the free end of the leaf spring 733-. V

The disk 50 of the closure head .46 is prel'- erably provided with a threaded opening 89 located above the open end of the gasolene reservoir 29. in this opening the neck of a filling funnel 90 is removably threaded. A suitable cap or cover plate Ell is hingedly mounted as at 92 upon the upperend ot' the funnel. By means of this tillingiiumiel at tachment, the gasolene reservoir may be conveniently tilled.

Having now described the construction and arrangement of the several parts oliny improved carbureter. its operation will be understood as follows: The. reservoir 29 having been su 'zp'lied "with gasolcne and the pipes 84' and 85 connected to a kerosene tank and a water tank respectively. the valve 78) he valve rod (35) controlling the supply of gasolcnc is then turncd'until the numeral (1 or 7 on the head of the valve is below the spring 5-), thus indicating that the valve is about three-fourths open. After the engine has been started on The outer ends of these.

lla)

the gasoleue as the operating fuel, the valve.

69 controlling, the kerosene supply isopened until the Indicating numeral"7 is -at the upper side of the valve head and the water,

control valve is also opened until the numeral 4 or 5 is uppermost. After the lapse of a short time or until the body It) is fairly hot, the valve 79' is turned to its open posi* two so as to admit both the water and kerosenc oil through the ports .82 and passages 78 to the orifices 65 at opposite sides oi" the car- 7 bureting chamber. The supply of gasolene is now,reduced anti the engine run on this entirely exhausted. gasolene supply requires only about eight or ten minutes after which the engine will opreduced gasolene supply until the same is he exhaustion of this erate "entirely upon the kerosene oil as a fuel. It will be understood that in the intake stroke-of the engine piston, the valve 41 is drawn open by suction and the heated air drawn upwardly between the ribs 37 of the saddle plate over the hot exhaust pipe and into the mixing chamber proper. As this air passes into the mixing chamber, the oil and kerosene entering through the orificesmixes therewith and the whole is then drawn into the gas passage 25 of the body 10. The flame and products of combastion from the engine exhaust striking upon the walls of this gas passage heat the same to a very high temperature so that the kerosene oil will be completely vaporized.

' This oil and the water, it will be understood,

is initially heated in its passage through the pipes 84 and 85 as said pipes extend through the tube 12, which is itself highly heated by the passage of the exhaust gases around the same. Thus, the complete vaporization of the kerosene oil in its passage through the carburetor body is assured and it is finally drawn through the intake pipe 26 and into the explosion chamber of the engine cylinder, in proper condition forcombustion.

The auxiliary air supply valve at the top of the-'inixer body' is completely closed when the engine is started. This additional air supply is only necessary when the engine-is operating under a heavy load.

' By providing a gas passage through the carburetor body ofthe particular form illus trated in the drawings, the mixture of air,

oil, or water is held in contact with the heated walls of said passages for a maximum length of time so that the complete vaporization of the oil is assured, My improved cab bureter may also be very easily and quickly I arran ed in the engine exhaust pipe or remover therefrom and n view of the accessibility of the several operating parts, the device may he' repaired and kept in thorough working condition with but little expense or anual labor.

The carburetor mayfof course, be constructed in various sizes and also in other terms than I have indicated in th, accompanying drawings in order to meet various;

circumstiinces or conditions which may arise in connection with the use thereof. The several cooperating parts of the mechanism may also be modified in many minor respects and I therefore reserve the privilege of resorting to all such legitimate alterations in the form, proportion, and arran ement of the several elements as may he airl bodied within the spirit and scope of t e'invention as claimed.
