GARBURETER.

Specification of Letters Patent. Patented 1 3 .12 1915 Application filed September 2, 1913. Serial No. 787,803.

Tb all whom it may concern."

Be it known that I, VILLIAM'iM. GENTLE, of Los Angeles, county of Los Angeles, and

State of California, have invented a cerp advantageous features, and in the novel and improved construction, arrangement and and which by its compactness andarrange' combination of parts as. will be apparent from the description and claims that follow hereinafter.

. Objects of the invention are-to provide a novel, new' and useful carbureterthat is simple in construction and operation, strong and durable, effective inaction, that enables quick adjustment of parts, that is economical in use and easily cleansed.

One object of the invention is to provide a gas generator that is outsideof the fuel bowl soas to avo d generating a gas therein and that will be a part of the carbureter ment will enable it to be combined therewith so that the device can be manufactured within the limit of size that is now generally allotted by engine builders tothe space for the carburetor.

Another object of the invention is to provide the carbureter with a preliminary electrical gas generator that'is also a part thereof and that can be dispensed with after the other gas generator hasbeenput into opera-y tion;'and whichwill heat only the fuel in thefuellnozzle and connections thereto.

Another object isto provide an air concentrating valve that will operateto converge the air passing through the carbureter around the fuel nozzle, and means for automatically reducing or increasing the converging force upon the nozzlefas the throttle valve is opened or closed, whereby.

a greater or less amount of fuel will be drawn by suction from the fuel nozzle.

causing the air. concentrating valve to operatein unison with-the-throttle valve and the auxiliary air valveto reduce the con sumption of fuel' as' thethrottle is opened;

1 and to combine all'these p'a'rts within the-- carbureter and be apart thereof.

Another'object of the invention is to"pro-' sufficient to reduceiit to a degree of rarefaction whereby its expansive property will be impaired and thereby diminishing its power producing quality when mixed with fuel and subjected to combustion.

,Another object of the invention is to provide ameans of adding to the 'carburet-er,

and which-when added to will be apart thereof, of an'auxiliary fuel supply mechanism, the function of which will be when added thereto, to operate as an engine starting and pr ming.- device; whereby the carburetei" can be used with a fuel,-that while cold, is of restricted explosive quality. The auxiliaryfuel receptacle being designed-to contain and to "supply tov the -fuel nozzle when needed a fuel, that while cold, is of high explosive quality; and that can be used to'sta-rt the engine or to invigorate the ac tionv of the other fuel whenever needed. Other objects and advantages of the'invention will be apparent to those skilled in the art from a consideration of the following description and claims, and of the preferred form of construction embodying it,

taken in connection with the accompanying drawings in which:

' is a section through the part 104 of the heating device shown in Fig. 7 with a cap 108 in section added thereto, the associated parts being omitted for the salve of clearness.

.The carburetor consists of a fuel bowl that is connected to a fuel tank not shown by a pipe 21 and coupling 22, the latter being of the usual construction used in joining the carbureter to the fuel supply tank.

The intake valve 23 and float 24 and the I parts thereof are also of usual construction and are shown in my prior Patent No. 1,0609% issued April 29th, 1913.

The fuel bowl 20 is provided with a tubular flange that-is centrally located therein and integral. with the bottom thereof. and extends upward therefrom to the top of the bowl, forming thereby an air passageway 26; and the opening'through the tubular flange is preferably made substantiaily'the diameter of the opening in the engine manifold to which it is to be at tached, but it may be madeof either greater or less dia neter.

The top of the fuel bowl 20 is closed by the'screw cap :27 that has centrally located thereon an upwardly extending tubularlike throttle valve casing 28 upon the upper end of which are flanges Z and holes 30 that are designed to fit a. similar construction on the intake end of an engine manifold and to be secured thereto by bolts passing through the holes 30.

A downwardly extending tubular flange .31 on'the cap 9? encircles a portion of the upper end of the tubular flange 25, the

opening between the two parts being reduced to a steam-t ght lit.

The diameter of the opening through the casing is the same as that of the air passageway Q6 and registers therewith, forming thereby a continuous air passageway.

A. throttle valve is secured by a screw 31 in a shaft 33 in a position to control the passageway The shaft 33 is mounted in the casing 28, and on one end thereof there is secured a throttle lever 35 that is adapted been rotated ninety degrees; thereby limit in; the movement of the throttle lever so that it can only move the valve 32 from its closed to its fully opened position and vice versa. A set screw. 42 is provided in the hub of the stop 37 so that it can be adjusted lug 45 is held against the auxiliary air,

valve 43 by the spring 43. The other end of the spring 48 abuts the not 49 that is screwed on'the end of the shaft 33. The lug 4 5 normally engages ,a lug 50 that is integral with and on the outside wall of the auxiliary air valve 13, and the lug 50'is normally held against the lug 45 by the ac-v tion of the spring 54: one end of which is secured to the edge of the valve 43 and the other end being secured to the ridged part 5%, see Figs. 6 and 7.

By this construction it will be readil seen that when the throttle lever is operate to move the shaft 33 and thereby open the valve 32 that the auxiliary air valve 43 will also be operated automatically to uncover the port 51 in the casing 28 and port 52 in the valve plate 53; see Figs. 6, 8 and 9. The valve 4-3 can also slide outw rdly on the shaft 33 to open the ports 51 and 52 and thereby relieve anypressure in the carburetor due to baclr fire from the engine, The plate53 is adjustable 'in the guide 5i by the set screw 55, whereby the port openings can be enlarged or diminished in size, thereby regulating the supply of air between the throttle valve and the engine. lhis auxiliary air valve was disclosed in my prior Patent 'No. 993,516, issued May 30th, 1911. and was made and successfully ouerated. The construction shown herein is substantially the same as that in a recent application for an improvement on carbureter filed by me lllay 26, 1913; Serial No' 770,049, and which has been heretofore referred to. The present construction while not departing from the principles disclosed in the prior patent is a more practical. economical, useful and expedient arrangement and operation of the auxiliary air valve. I

Within the air passageway 2G there is adjustably mounted on air concentrating valve 56. The body portion of this valve is tubular in shape and the outside. diameter is slightly smaller. than that of the air 'passageway so as to provide a slidable fit of the valve therein. The upper portion ofthe valve 56 is cut intoa plurality of isosceles triangular like spring points 57. each of which is bept inwardly about forty-five degrees toward a common center; forming thereby a restricted opening whereby only a part of the air necessary to operate the engine on high speed will pass through. This concentrating valve 56 is made of spring metal so zle, and consequentlya greater or less amount of fuelwill therefore be drawn from the fuel nozzle exactly in proportion to the opening of the throttle valve. In other words, it is necessary that a greaterjamount of fuel be mixed with the air when the engine is on low speed and operating with the throttle valve but slightly open, than when 1 the throttle is fully open and the engine running at high speed; consequently it is necessary to diminish the fuel as the speed of the engine is increased, and this valve operates to accomplish that result. It can be readily seen that with the points 57 extended inward over the fuel'nozzle that they would cause a greater concentration of air around it than they would if they were moved upward away from the nozzle and vice versa; and as fuel is drawn from the nozzle'by suction, the varied concentration will operate to vary the amount of fuel consumed. The points 57 also operate to give the air and fuel a mixing action. As seen in Fig;

5 the points can be slightly turned so that 'one edge of each is slightly higher than the next edge. to it whereby the air passing between the points will be given a rotary action as indicated by thearrows in this figure,

thereby producing a 'cyclonical suction on the fuel nozzle. a.

Integral with the body of the valve 56 are two downwardly extending arms 58 that are turned outwardly at the lower end thereof, and the'lower loose ends are mounted slidable in the guide plates 59. One end each of the guide plates 59 are secured to bosses 60 on the bottom of the bowl 20v'by screws 61. The other end of the plates 59 are secured by screws 62' to bosses 63 on a heat device or gas generator 83 that will hereafter be explained. The arms 58 are mounted slidable on the plates 59 by screws 64 said screws having free movement in the slots- 65 in the plates 59 so that an adjustment of the valve 56can be made relative to the concentration of air necessary" around the fuel nozzle of the carburetor.- This valve is shown in itslowest position in Fig. 9, the throttle valve 32 being closed, and in .its highest position in Fig. 7 with the throt- .of the engine decreases.

tle fully open. The valve 56 is operated by' the throttle lever 85 to move it from its lowest toits highest position and vice versa; said movement is accomplished by the following means: Bell cranks 66 are shown pivoted at 67 one to each side of the gas generator 83. One of the arms of the bell cranks 66 are slotted at 68 to fit the screws 64: and to permit of-an upward and downward movement of said arms to move the screws in the guide .65 and thereby move the arms 58 to raise or lower the valve 56. A rod 69 yokes the two cranks together. A link 70 connects one of the bell cranks to one arm of a bell crank 71 that is pivoted at 72 on the side of the carbnreter bowl 2.0. A link 73 connects the other arm of this bell crank with one arm of a bell crank 74 that is pivoted at 75 on the upper end of the bowl 20, and a link 76 joins the other arm ofthis crank to the throttle lever 35. By this construction the air concentrating valve 56 would be moved upward away from the fuel nozzle 86 as the throttle valve 32 is opened by the throttle lever. This would result, as heretofore stated, in reducing the amount of fuel used as the speed of the engineincreases and vice versa in increasing the the amount of fuel consumed as the speed The principle involved in the operation of this valve was partly shown in my application for Letters Patent heretofore referred to by Serial N 0. 770,049 and filed May 26, 1913; but the present construction contains a plurality of new, and useful features that are not disclosed in the prior application, and that are especially adapted to and are indispensable in the present application. Extending downward from the bottom of the bowl 20 and to one side thereof is a threaded nipple 77 through which there is a fuel passage way 78, that, through connecting parts, leads to the fuel nozzle 86. The nipple 77 is connected to a valve casing 79 by a 1 ipe 80 and, coupling 81. The valve casing [9 has a threaded nipple 82 on to which is secured a cylindrical casing'83. The nipple 82 is bored out so as to form a blunted V shaped opening large enough to take in the end of a flexible pipe 84. One end of the pipe V8% is soldered into the V shaped opening in the nipple 82 soas to hold it securely in place in said nipple and to prevent leakage therefrom. The pipe 84: is turned at right angle to the end in the nipple and then coiled to form a cylindrical like coil slightly smaller in diameter than the inside diameter of the cylindrical casing 83; and the loose end of the coil is then bent in toward the center thereof and'turned' into alinement with the fixed end. The loose end is then inserted and soldered in a blunted V shape cross'pipe 85 there is screwed a fuel nozzle wires 101 and 102.

26 that extends upward through the casing 83 and through a boss 87 on said casing to a point slightly above the level of the fuel in the fuel bowl 20, the upper end of the nozzle being central in the air passageway 56. 'Qhe boss 87 is threaded to receivcthe packing ring 88 and nut 89 to prevent leakage from the cylinder around the fuel nozzle 86., Screwed into the lower arm of the cross pipe is a needle valvecasing 90 that has on the upper end thereof suitable packing to prevent leakage from the fuel passageway 7 8. The lower end of the casing 90 extends out 01" the cylinder 83 through a boss 91 on said cylinder, and said boss is threaded to receive the packing ring 92 and nut 93 to prevent leakage from the cylinder 83. A needle valve stem extends upward through the casing-9O and the cross pipe 85 and through the fuel nozzle 86 into a position to either open or close the port in the fuel nozzle 86. The needle valve stem is threaded through the casing 90 and is adjusted therein by the hur ill on the lower end of said stem. open end of the cylinder 88, and to this cap on the inside thereof is attached an electrical heater 98. The heater is tubular cylindrical in shape and is slightly smaller than the in side diameter of the cylinder. 'l he heater 98 is secured to the cap 97 by screws 39 and 100 that also serve contact post for the nected with a switch and hattery not shown, but n'hich will operate to pass electricity through the heater when desired to supply to the gas generator a preliminary heat. The electrical heater is insulated from the cap 97 and also from any heating" element entering into the cylinder 83.

Centrally outuardl extending train the cap 97 is a threaded tubular flange 103 through which one end of a pipe 1% is inserted into the cylinder 83 and screwed into the remaining arm of the cross pipe 85. A packing washer 105 is interposed between a head 106 on the pipe 104- and a nut 10? onv the flange 103 thereby preventing leakage from the cylinder around said pipe. The outer end of the pipe lO-l can'he closed by a cap 108 as shown in Fi 13 and the device operated without the audition of the priming attachment that will be described later.

The electrical heater 98 is for the purpose of supplying to the gas generator a preliminary heat as heretofore stated, to generate therein suliicient gas to give the cnglue its initial movement. After the engine is put inlo: operation another means is pro} ride'dior supplyingheat to the gas generalor'thatis constructed as follows: A pipe 109 is attached to either the hot water jacket or the exhaust pipeof the engine not shown, and connected to the cyl nder 83 as shown A threaded cap Q? closes the These wires are con pass from the engine into the cylinder 83 and around the generating coil 81; the! Ward passing from the cylinder by the discharge pipe 119. from howl 20 will be heated and after it has passed trozn the fuel bowl and generated into an explosive gas as it passes through the coil St and before it is discharged from the fuel nozale $6 into the air passageway 36 Where it can be taken up suction into the engine. The cylinder 83 is located directly below the intake opening of the air passage way '26 so that the air entering therein. will pass over the heated suri ace of the cylinder thereby tempering it so that it will no re readily mix with the fuel; but this change of temperature will not be suiiicient to impair its expansive. quality by ratification. 4

it will he seen from the drawings that the gas generator is located between the fuel bowl 20 and the fuel ncazle 86', and that a valve 111 is placed between the-gas generator andithe fuel bowl. The purpose of this construction is to limit the amount of gas generated to the exact quantity necessary to operate the engine. .Nith the valve 111 interposed as stated the engine operator can at will either increase or decrease the flow of fuel from the bowl 520 to the generator, thereby enabling him to gage exactly the amount of fuel necessary to give him the best results in operating his engine; it is ohvious to say that he can close the valve to entirely cut oil the supply offuel,

It can readily be understood from the foregoing description of the parts and their operation that they collectively form a complete carhureter that can be operated to'iperform all the functions of such device. in addition to the foregoing carbureter. there has been added theieto a priming and start- By this means, the fuel in; mechanism that when added to will he a part thereof, and operate jointly with the carburetor to perform a common function.v is desirable when operating an engine.

It that is using'e fuel of restricted explosive quality while cold, toliave handy means for invigorating the action of the fuel and .also to make easy the starting of the engine, and to that end I recen ly madean, application for Letters Patent covering a carhurater of that nature. The application is known and heretofore referred, to as Serial pipe 104: and in its place is secured a valve fits into the groove 115 on the side of the fuel bowl 20, see Figs. 1, 6, 7, and'12. A ledge 116 on the bottom of the fuel bowl 20 maintains the other fuel bowl in its fixed position. A'nipple 117 on the bottom of the bowl 113 is joined to the valve casing 112 by a pipe 118 and a coupling 119. There is also a nipple 120 on the bottom of the fuel bowl 113 through which fuel is-supplied to said bowl by pipe 121 that is joined to the nipple by the usual coupling. The pipe 121 is connected with a fuel supply tank not shown; said tank being made to supply a fuel of high explosive quality. The fuel bowl 113 is provided with an inlet valve 122 and float mechanism 123 of usual construction. A screen 124 is soldered over the opening through the nipple 117 to prevent dirt from filling or obstructing the fuel passageway therethrough. This passageway 78 is continuous from both fuel bowls to the fuel nozzle through said valves 111 and 125, and when both valves are open fuel from both bowls will flow to the fuel nozzle: but

normally only one of the valves are open.

These two valves are provided with levers 126 that are joined together by alink 127.

One end of this link is extended and provided with an opening 128 that can be connected with a controlling means of common construction that can be located convenient to the engine operator. Therefore these valves can be operated to use either one or the other of the fuels exclusively or to use a greater or less amount of each just as the operator deems best to secure the most satisfactory results in driving his engine. Drain cocks 129. 130 and 131 are provided so that the contents of each fuel bowl can be drained oil and cleaned.

In cleaning the bowl 20 and its associated parts, the cap 132 is removed and the valve 111 opened and the valve 125 closed.

The,n the two drain cocks 129 and 130 can be opened and the bowl 20 flooded with a cleaning solution that will drain off through the drain cocks. The bowl 113 can be cleansed by removing the cap 133 and opening the drain cock 131 and flooding the bowl with a cleaning solution. After the bowl is sufficiently cleansed the passage way through the nipple 117 and its associated parts can be cleaned by opening the valve'125 and the drain cock 130 and allowing the cleaning solution to flow through the drain cock. A screen 134 is provided in' the fuel bowl 20 to prevent foreign matter from passing throughfrom the upper to the lower part of the fuel bowl and thereby obstruct the-fuel passe eway 78.

In openation, the carbureter would be attached to the engine manifold as heretofore hot water jacket or the-exhaust pipe of the engine and the levers connected to control ling means and made handy to the engine operator, the arrangement and construction of said control 'and connection being well understood by those skilled in the art, and not here shown. Assuming that the caroureter is to be used without the priming attachment, then the pipe 104 would be capped as heretofore described and the valve 111 would be opened to permit the fuel from the bowl 20 to flow downward through the passageway 78 into the pipe 104. The electrical heater would be put into operation to heat the pipe 104 and the associated parts and thereby generate a gas suflicient in quantity to start the engine. After the engine has been put into operation the electrical heater can be continued in use until the other generator is active and supplying sufficient gas, when it can then be discontinued. Y In operating the carbureter with the priming attachment; and with the fuel bowl 20 supplying a fuel of restricted explosive quality and the fuel bowl 113 supplying a fuel of high explosive quality, the operation would proceed as follows. The valve 111 would be closed and the valve 125 opened and the electrical gei'ierator put into operation to generate gas from the fuel from the bowl 113. After the engine has been put into operation and 1151s continued to run long enough to put the other gas generator into operation, then the operator can gradually close the valve 125 and open the valve 111 whereby the engine will continue to run and eventually operate alone on the fuel of restricted explosive quality when the valve 111 is fully opened and the valve 125 fully closed. If after the highly eX- plosive fuel has been discontinued and the engine should begin to lag or lose power, it can be invigorated by slightly opening again the valve 125. If the engine has been stopped while using the fuel from the bowl 20 and the fuel passageway 78 stands full of the fuel of restricted explosive quality and the operator desires to start up the engine again; the fuel can be drained from the passageway 78 by closing the valves 111 and 125 and opening the drain cocks. After the fuel has drained from the passageway the drain cocks can be closed and the valve 125 opened and the engine started. as heretofore described. 125
