The present invention relates to a device for heating the manifolds of internal com` bustion engines and facilitating starting yof the same. r

Anzobject of the present invention is to vaporize the ordinary fuel forthe engine by bringing the fuel into4 contact with heat and igniting the vapor by an electric current vof the usual high tension.

. may

Another object 'of the present-invention is to provide a heater which may be controlled from the instrument board of an automobile, or the like, and which may utilize the electric energy of the storage battery of the automobile for setting the heater in operation.

A further ob'ect 'of this invention is to provide aA mani old heater wherein the fuel for the engine may be utilized for operating the heater, and wherein means is provided for cutting olf v the supplyi of fuel. tothe heater after the latter has been operated suiliciently to heat the manifold, and to thus prevent waste of fuel after the engine has been started.

The invention still further aims at the provision of a device of this character which be embodied in the construction of the manifold; which may be installed. upon an engine without altering the arrangement and construction of its parts; and which may be uickly and easily connected to the source of fuelsupply andto the source of electric energyof the usual automobile.l

Our present invention relates to certain apparatus similar to that described but not claimed in our oopending application,`Ser. No. 525,106, filed Dec. 27, v1921, and entitled Manifold heaters `for internal combustion engines.

With the'foregoing and other objects in view, the invention will be more fully `dand exact description of the `in scribed hereinaftenand will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts through out lthe several views,

Fig. 1 1s a vertical Sect-ion, partly diagrammatic, showinga manifold heater constructed according to the present invention.. Fig. 2 1s a vertical section taken axially at right angles to the showing in Fig. 1.

Fig. 3 is a side elevationvof a portion ofy i the lower end of the casing of the heater.

Referring to the drawings, the body part of thef device may be vmade in the form of lan integral casting, as shown, and which has a horizontal pipe or manifold portion 10 adapted to be connected to the side of an engine in theusual manner, and which has an intermediate branch and intake connection 11 which is arranged for connection with a carbureter or other source of supply.' Surrounding the juncture of the portions 10 vand 11 is a heater casing 12 which extends above and below the manifold and which, at its upper`end, is preferably reduced in cross sectional area and rounded to provide an annular flange 13 over` which is detachably threaded a cap 14. The cap 14 has a closed top and is preferably provided in its side with a circular row of perforations or vents 15 through which consumed gases and air may escape. The cap 14 also has a reticulated screen 16 therein placed below the openings 15, and which is adapted to prevent flame from passin upwardly through the cap.

The'V lower endofl the casing 12 is also reduced to provide an air inl/et 17, upwardly through which air may circulate forpromot-A ing combustion within the casing. The' cas- 4ing 12 has a large opening 18d in one sidel which is normally closed by a combined sup' porting and cover plate 19 held against the exterior side of the casing 12 by removable fastening devices 20, such as screws, as shown in Fig. 3. rl`he plate 19 carries upon Aits inner side a receptacle y21 which is open at its top and which is arranged to receive receptacle 21.

providing a measuring chamber 27 therebe tween of sufficient size to contain a single charge of fuel from the tank pipe 28 for heating the manifold.

Fitting over the upper end of the receptacle 21 is an electric resistance coil or heater 30 which is encased in a jacket or band 31 -of metal or other suitable material, and which at one endv is connected to an insulated binding post 32 detachably secured in the cover plate 19 and at its other end is grounded in the receptacle 21. A hood 33 surrounds the burner and is spaced about and slightly above' the upper end of the Vapor accumulating at the top ofthe wick rises in the hood 33 and spreads over the top of the wick 22 in moving upwardly through the casing 12. The plate 19 also carries a spark plug 34 the electrode of which projects into the hood 33 and in slightly spaced apart relation to the top edge of the receptacle 21. When the spark plug is closed in circuit, it isl adapted to ignite the gas or vapor in the hood 33. The burning vapor rising through the hood is brought into. contact with the top of the wick 22 and consequently the wick is lighted.

A control rod 35 is mounted in any suitble manner for controlling the closing of e electric circuits, and for controlling the feed of fuel to the receptacle 21. This rod 35 may be connected to a supporting arm 36 carried `upon a rod 37 which projects outwardly from the plate 19. The control rod 35 carries a stud 40 which operates in a slot 41 formed in one end of a bell crank lever 42, the other end of which is pivoted to a link 42a connecting together the arms of the -

valves

25 and 29, so that when the control rod 35 is pulled in a downward direction, as shown in Fig. 1, the valves will change position. When the Valve 25 is closed as shown, the valve 29 is open so that liquid from pipe 28 fills the measuring section 27, and when the valves change position the flow from pipe 28 is cut off and the liquid flows from the section 27 into the receptacle 21 and is raised through wick 22.

The control rod 35 also carries a spring contact 43 arranged to wipe the end of the post 32 and connected to a wire 45-which leads from a source of electrical energy, such as a storage battery 46, the circuit having therein a lamp 48 or other suitable indicator for showing when the circuit through the wire 45 is closed. The indicator or lamp 48 may be grounded as shown at 47.' Thev vibrating coil 50 may be connected by branch wire 44 to the end of the post 32 and include the coil 50 in the circuit when the contact 43 is closed. Also a high tension `lead 49 from vibrating Vcoil 50 extends to the spark plug 34.

It is apparent that when the parts are in the position shown in Fig. 1, the post 32 and Vibrating coil 50 Aare closed in the circuit with the battery 46, and the heating coil 30 getting to operate the control-rod after the engine was started to extinguish the heater. After the manifold 10 ,has been heated to the desired extent, the control rod 35 is drawn downwardly to open the electric circuit and to open the valve 29 'and close the valve 25. plenished with the fuel so that the device is automatically placed in condition for subsequent use.

With the foregoing and other .objects in view, the invention will be more fully de- The receptacle 21 is now red scribed hereinafter, and will'be more particularly pointed out in the claims appended hereto. 1
