Specification of Letters Patent. Patentd ltalgll, 1919:.. mi Application ed April-21, 1916. Serial No.'92,"66. I l

invention is `more clearly understood from the following specification, the subject mat- -ter of the claims, and =the views illustrated in the accompanying drawings, in which:

Figure l 1s a `vertical sectional vlewv through the device, showing the detail con# struction thereof.

Fig. l is a perspective view `showing the shown Fig. 5 is a' view inl elevation of one of the '4 T-bolts used in connection with the yoke of Fig-4 for attaching the device to2-an engine.

Referring to the drawings wherein similar reference characters denote corespond` ing parts throughout theY several views, 1 denotes the upper portionof the cylinders of an engine, 2 the exhaustv manifold, and.

3 the exhaust pipe leading centrally therey from.

The exhaust manifold 2 consists prefer ably yof yan elongated cylinder provided with rounded ends and its exhaust pipe 3 extending from its lower side at a point midway between its ends and disposed obliquely therefrom for a portion of its distance. At onefside of the exhaust mani` fold 2 are formed the ported exhaust nipples el.' adapted to-be seated in the ends of-` the exhaust ports of the engine.

TWithin the exhaust manifold 2 is the in-v` take manifold 5 provided at one of its sides k with the intake nipples 6 which. project* through the side of the exhaust manifold?` and are adapted to be seated within the in;

take ports of the engine. f` The intake mani:-A

fold` 5 is also preferably formed of an elongated cylindrical construction provided with rounded ends, and 4is of less length and less diameter than the" exhaust manifold 2 to provide ample space therebetween, and extending from the under side ofthe intake manifold 5.' and from a point substantially midway between its ends is' the intake pipe y7 whichl is also disposed in oblique'direction {'ffrom the intake manifold 5 for a portion of :fits distance-and within and in spaced relaj vtion to vtheexhaust pipe 3,Ithe lower portion of th-intake pipe 7 being curved later- `ally in 'acute 'angular relation toprovide the attaching end 8 W'hich project'sthrough and ,i'beyond one 'of the side ,walls `of the exhaust 'p1pe.3.':Within the end 8 ofthe intake pipe attaching end l8 of the intake pipe'7 is any Lsuitable form of kerosene carbureter 1l) supwith oilvbythe pipe 11. Secured to thecarbureter l() is the Vhot air pipe 12, provided with the .butterfly-valve 13 operated 'byfany suitable means. The hot air pipe;

reter 10. As shown,`.'the open end of the hotair cas- 2 5 .ing 1svdisposed innermost and adjacent the juncture of the exhaust' p-ipe l3 with the exhaust 'manifold so vthat the heat radiated 1 from them and the surrounding warm air.

t ,'may'be drawn directly into the hot air casing and again superheated in its passage along "beneath the exhaust manifold just prior to itsfentrance into the kerosene ear- ,buret'en y .Y

The intake manifold ,5 and its intake pipe "7 are supported -in ,spaced relation to and '.Within'the exhaust vmanifold 2 and its exhaust pipe A3 tlnough the medium of the -intake nipples/6 which ,project from one side "of the intake'manifold 5 and open through one 'side wall of the exhaust manifold 2. The nipples 6 thus connect the intake manifold5. with the exhaust manifold 2, and at the oppositesside o f the intake manifold 5 vthere is a lletgor neck which connects -adjacent wall`of the exhaust manifold 2. Also extendingfrom the outer Wall of the intakepipe 7 at any suitable point is another llet or yneck'similar to the fillet or,

.neckj15 for securing this side of the intake pipe 7 tothe adjacent wall of the exhaust pipe 3.- l The intake manifold 5 and its intake pipe 7 are also additionally reinforced 4 and supported by the Vattaching end 8 of the ntake pipe 7 being rigid with and opening through one of the walls of the exhaust pipe .i s'th'ebuttery valve 9 operated through 'aiiysuitable means. 2,Suitablysecured to the this wall of thiintake manifold -5 with the screw threaded in the outer end ofl the neck 15 isthe tube 17 ofthe valve casing 18 provided With any suitable form' of valve 19 actuated by the valve stem 2O which extends .t0 the dash board of the automobile or other4 70 suitable point7 and connected to the valve casing 18 is the water pipe or hose 21 leadirg from' any suitable source of water supp .Y- i

F or supplying gasolene to the intake pipe 7 of the intake manifold 5`the lower fillet tends to the dash board of the automobile or other convenient point', and for supplying 85 gasolene to the valve casing 23 the pipe or hose 25 is provided which leads to any suitable source ofv gasolene supply.

For securing the device upon an engine the yokes or U-shaped bolts v26 provided 90 with'the threaded ends 27 and the nuts 28 thereon are employed. These yokes 26 extend around and embrace substantially half of the circumference of the exhaust manifold 2 and have their threaded ends 27 se- 95 cured in the apertures 29 formed in the ends ofthe heads 30 upon the stems 31 of the T- bolts, the stems 31 of these bolts being designed to pass through bores formed between the cylinders of the engine and secured 101 thereon by the nuts 32 which engage the threadedends 33 of the T-shaped bolts at the oppositeside of the engine. This means of attaching the device upon the engine firmly Vsecures the same thereon with the exhaust nipples 4 of the exhaust manifold 2 securely seated in the ends of the exhaust ports of the engine and the intake nipples 6 firmly seated in the ends of the inlet ports ofthe engine, which connections may be efliciently sealed with any suitable form of gaskets or the like, the attaching end 8 of the intake pipe 7 being connected to the 'kerosene carbureter 10 in any suitable manner as at 34 and the exhaust pipe 3 having 115 its end 35 connected in any suitable manner with the exhaust conducting pipe.

The operation of the device is briefly described as follows:

To mart the engine the valve stem 24 is manipulated for actuating the valve in the valve casing 23 so that the gasolene will be drawn through the pipe 25 and into the intake pipe 7 and therethrough into the vintake manifold 5 and into the respective cylinders of the engine bythe suction' created therein and air may be admitted to the gasolene from the air pipe 12 by the proper manipulation of the butterliy valves 9 and 13 if desired.. The engine will now run 130 by the gasoline supplied thereto until the exhaust manifold 2 and its pipe 3 and the intake manifold 5 and its intake pipe 7 become heated by the exhaust gases of the engine whereupon the kerosene carbureter -10 will be so operated that the kerosene will the port 16 in the upper neck 15 inra fine stream and by the heat of the exhaust gases which'have heated the surrounding walls of the exhaust manifold 2, the intake manifold 5 and the fillet or neck 15 is readily 'converted into steam and commingles with the vaporized kerosene and gasolene, the gasolene, however, being gradually cut olf by manipulating the valve stem 24 inthe opposite direction until the gasolene is entirely cut olf and the engine now runs eiiicientlyupon the kerosene mixture, the kerosene having been thoroughly vaporized by the air heated in the casing 14 which passes through the hot air pipe 12 into the carbureter 10, the steam increasing the efficiency of the mixture. v

Having described my invention, what I claim as new and desire to secure by Letters Patent, is l 1. In an internal combustionv en 'ne, the

- combination with an exhaust mani oldhaving` a depending exhaust' pipe upon its lower side and middle portion, of an intake pipe, a part of which is `wholly within said exhaust pipe, while the remaining part of said intake pipe has on its receiving end a lateral extension fitted to the under side of the exhaust manifold and provided with a receiving opening immediately adjacent the exhaust pipe of said manifold, whereby initially heated air from the exhaust pipe will enter said intake.

2. In an internal combustion engine, the combination with an exhaust manifold having a discharge pipe and also having an intake manifold positioned within the exhaust manifold, of an integral hollow neck connecting said manifolds, a liquid supply pipel connected to the outer endof said neck, and a valve to regulate the supply of liquid to said neck.

3. The combination with an exhaust manifold operatively connected to the exhaust ports of the engine and having a depending exhaust pipe on its lower central portion, of .an intake pipe operatively connected with the intake ports of the engine and disposed vpartly within said exhaust pipe and manifold, said intake pipe having its exterior portion or receiving end shaped to fit the under side of the exhaust manifold and extended inwardly to apoint adjacent the point of union of said exhaust pipe with said exhaust manifold, whereby the only opening in the intake pipe will be immediately against said exhaust pipe.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.A
