THOMAS A. unison, an, or BURLINGTON, NEW JERSEY.

To all whom may concerns Be it known that I, THOMAS A. EDIsON,

Jr, a citizen ofvthe United States, and a improvements in means forsupplying the mixture of vaporized gasolene or other fuel to internal combustion engines.

In startinginternal combustion engines,

particularly in cold, weather, difficulties are frequently encountered in vaporizing the fluid fuel to an adequate e'ictent to cause the r p passed.

cylinders of the engine, and I have illustrated my inventionas an attachment adapt edto be secured between the carbureter flange and the flange of the induction pipe.

Referringparticularly to Figs. 1 to 6 inclusive, at'1 is. shown 'the neck of the carbureter or pipe leading therefrom, and at 2 the flangelof the same.- At 3. is shown the induction pipe and at 4 the flange of the same. A casting 7 isrprovided having ex tendingtherethrough a cylindrical opening 8 of somewhat greater. cross section than the cross section of the carbureter neck and induction pipe, and adapted to be secured between the'carbureter flange and the induction pipe flange with the opening 8 inline with the carbureter. neck and the induction pipe so as to constitute a. conduit connecting the two. .In the casting 7 and surrounding the opening 8 and separated therefrom by a thin wall is an annular opening 9 which is adapted to receive anelectric heating coil 13., The opening 9 is adjacent to the carbureter flange 2'. Adjacent to the induction pipe flange 4 is an annular opening or chamber 10 surrounding the opening 8 and separated therefrom by a thin wall. The electrical heating coil 13 and the chamber 10 adapted to receive heated fluid are therefore in'thermal'relation tothe opening 8. The casting 7 issecured between the induction flange 4 and the carbureter flange 2 by bolts 5 and 6 orother suitable means, and gaskets l1 and 12, .preferably of asbestos, are provided between the casting 7 and the carbureter fl'ange2 and induction pipe flange 4 said circuit 20 being provided with a switch 22 for controlling the same,

Surroundingthe thin wall ofthe casting 7 between the opening,8 and the annular opening or chamber 10 ,isjan annular baffie plate23 provided with openings or cutaway portions arranged in a manner hereinafter describedfl' The. opening; 8 is pro- 1 vided with wires or metallic filaments 24 so disposed as to have large portions of the same in contact with the walls of the casting 7 surrounding the opening 8. A single wire may, of course, be used. .This mass of wire is held in place between members 25 extended across the ends of the opening 8 and secured in any suitable manner. I have illustrated the opening 8 as slightly beveled at its ends, and the members 25 correspondingly beveled at their ends and held between the casting 7 and the gaskets 11 and 12 by the pressure produced by the flanges 2 and 4. An inlet pipe 26 is provided leading into the chamber 10 through its outer wall and located diametrically opposite thereto is an outlet pipe 27 leading from the chamber 1.0 through its outer wall. The pipe 26 is adapted to be connected to the exhaust of the engine or to be fed with water which has been heated by cooling the engine. The exhaust gases or heated water enter through the pipe 26, pass through the chamber 10 on both sides of the annular baflle plate 23, and flow out through the outlet pipe 27, the path of the heated fluid being indicated by the arrows in Fig. 2. The portion of the casting 7 containing the chamber 10 may be designated as a fluid heater. The openings 28 in the baffle plate 23 are so arrangedthat they increase in size in passing through a point opposite the inlet pipe 26 around the two halves of the baffle plate to a point opposite the outlet pipe 27. Or, the holes may be of the same size, but increasing in number from a point opposite the inlet pipe 26 to a point opposite the outlet pipe 27. The heated gas or water which enters through the pipe 26 has its maximum temperature at this point and has become cooled somewhat be fore flowing out through the pipe 27. The arrangement of openings in the battle plate 23 causes the inner wall of the casting 7 to be heated uniformly and causes a uniform distribution of heat through the deflecting wire or wires 24. An air inlet 46 is provided in the casting 7 at a point remote from the inlet pipe 26. From the air inlet 46 a pipe 29 leads through the chamber 10 throughout substantially one half of the same to a point substantially diametrically opposite the inlet 46, and leads into the opening 8 through the bafile plate 23 and the inner wall of the casting 7 at 30. Surrounding the air inlet 46 andsecured to the casting 7 is a hollow member 31 provided on its interior with a port adapted to be closed by the valve 32 and provided also with an opening 35 extending about half way around its circumference and communicating with the port. \Vhen the valve 32 is closed, no air can enter through the opening 35 into the space communicating with the opening 46. Surrounding theportion of the member 31 containing the opening 35 a cup-shaped member 34 mounted on the member 31 so as to be rotatably adjustable and having openings 36, 37, 38 and 39, one or more of which may be brought into communication with the opening 35 by adjusting the member 34 on the member 31. The openings 36, 37, 38 and 39 communicate with the external atmosphere and by adjusting the member 34 so as to have a larger or smaller number of openings 36, 37, 38 and 39 communicating with opening 35, the supply of air which enters through the air inlet 46 and pipe 29 into the opening 8 may be controlled. The adjustably rotatable member 34 is provided with a knurled rim 40 to facilitate adjusting the same. The member 34 has an opening extending through it which serves as a guide for the stem 33 of the valve 32. The end of the stem is provided with a nut serving as an abutment 41 and a lock nut 42, and a coiled spring 47 is located between the nut abutment 41 and the stem guidingportion 34, serving normally to keep the valve 32 in closed position. A protecting cap 43 is screw threaded on the member 34 so as to protect the extended end of the valve stem nuts 41 and 42, and the spring 47. A resilient open ring 45 shown in extended position in Fig. 5 is seated snugly in a groove circumferentially surrounding the stem guiding end of the member 31, and frictionally engages the inside of the member 34 and servin to hold it in adiusted position.

The operation of my improved apparatus is as follows :Assuming that the plug contacts 17 and 18 are connected with the socket contacts 15 and 16, when it is desired to start the engine, the switch 22 is closed, which causes current to be supplied to the heating coil 13 from the battery 21 to heat the coil. The heat from the coil is transmitted through the thin inner wall of the casting and to the portions of the wire or wires 24 in contact with the wall. The wires rapidly become heated and readily communicate their heat to the mixture of air and gasolene or other fuel which flows from the carbureter into the opening 8 on its way to the induction pipe. By having a mass of metallic material of considerable area distributed throughout opening 8, such as wires 24, substantially all of the fuel mixture comes in contact with a heating surface, and the mixture is adequately heated to enable the engine to be easily started. After the engine has gotten into operation, the switch 22 may be opened. The exhaust gases from the engine or the hot water from the cooling chambers flows in through inlet pipe 26 into chamber 10 around the baffle plate 23 on both sides thereof and contacts with the thin inner wall of the casting 7 at points where openings in'the baffle plate occur. The exhaust gases or water flow out of the outlet pipe 27. The heat from theexhaust gases or water transmitted throughthe 3 thin wall of the casting 7 to the wire mass paratus.

and pipe 29 to the opening 8. The pipe 29' being surrounded by hot gases or Water, air

is introduced into the mixture in heated condition, thereby adding materially to the-efficiency and economy of operation of my ,ap- The cup-like member134: is ad-' justecl so'thatasufficient number of openings 36, 3 7, 38 and 39 communicate with the opening 35to furnish the necessary supply of air for this purpose. I

In F g. 7Ihave illustrated amodification ofmy' invention in which, instead of the wire mass 24, I employ a rotating helical de vice to throwv the mixture carrying the fuel particles against the innervva'll of the casting? to enable the heat fromthe same to be communicated to themixture. In this modification, ring-like members 50,..50 are threaded into the casting 7 at the two ends of the opening8,the ring-like members 50,

50 "havingbridging members 51, 51' which serve as bearings for the cone-like ends52, 52 of the shaft carrying the helical member 53. Ball bearings may also be provided,

Under the influence of the draft of the mixture," the, helical member '53 iscaused to rotate on its bearings and the fuel particles are thrown against the inside wall of the casting 7 and heated.

In F ig."8 I have illustrated a modified form of electrical heating device which may be utilized in any of the structures illustrated in the preceding figures. This form of electrical heater consists of a'plurality of radially disposed metal pieces 60 having their ends extended into the opening 8 and, 3 theportions ,without the opening 8 sur-' rounded by. heating coils 61. The ends of the metal pieces 60 which extend into the opening 8' are provided with perforated de.-- flectingmembers at an angle. to the normal line of flow'of mixture through theopening- 8, the deflecting members 62 serving to communicate heat conducted from the'wheating.
