-verted into dry gas while the fluid mixture is on I the way'to the engine cylinders.
Otherobjects of the invention are to supply a ;manifold construction which will cause the englue to operate cooler than heretofore, will resuit in less dilution of the ,crank case 611, will decrease the formation of carbon, secure greater service from lubricating oils, give:longer life to theexhaust valves and will enable, the motor to 20 operate with less vibration.
With the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novelfeatures hereinafter described in detail, 11-
2t lustrated in the accompanying drawing and more particularly pointedout in the appended" claim.
In the drawing: I 1 4 Fig. 1 is a top plan view of the improved manifold..
80 Fig; 2 is aside elevation of the same. ,Fig. 3 is a longitudinal sectional view taken on the line 33 of Fig. 2.
' Figs. 4 and 5 are vertical se'ctional' views taken respectively on'the'lines d-t andb-t of Fig. 2. 35 In the embodiment of the invention illustrated in the draw n 6 designates a metal casting preferably. of box section and having closed ends I! and B. A plurality of-exhaust nipples will, ii and i2, pro;|ect from one side of the casting, and
40 of course, when the casting is secured to one side of an engine, the nipples will receive the exhaust gases from the engine.
An imperforate web it is positioned within the casting and forms one side and the bottom of an.
dd intake passageway M that is disposed entirely within the exhaust gas passageway it formed by the'cazting. I
As best shown in Fig. 3, the ends of the passage way It are closed by ver'ticalwvebs It and the fuel fill mixture is introduced into the intake passageway .through a port I! in the top of the casting "which is adapted to be connected to any suitable carburetor. However, as my improved manifold 55 in a most eflicient way, distillates heavier than takes advantage of the heat of'the exhaust gases 4 'gasolines may be used in'place of or in conjunction with gasoline asa fuel for the engine. The manifold is of such a character that the engine may be started with gasoline as a fuel and then as the manifold heats up theuse of gasoline may 5 be discontinued and the engine operated by means of a distillate fuel.
Intake nipples i8, i8 and 210 project from the same sideof the castirigas the exhaust nipples and the intake nipples communicate with the passageway it.
The exhaust gases are discharged from the pas- I sageway l5 by means of a nipple 2i arranged at the bottom of the casting, but before the gases are discharged, they contact with the web i3 and this '15 transfers the heat to the incoming fuel mixture.
In order to better utilize the heat units impounded in the exhaust gases I extend a tube 25 through the intake passageway. The ends of this tube are connected tothe ends of the intake passageway and the interior of the tube communicates with the exhaustgas passageway so that some of the exhaust gases can travel through the tube and heat thein'terior of the intake passageway; 1
. From the foregoing it is believed that the op- :eration of this manifold will be obvious, but 'brief- 1y it may be stated that when the engine is running, the hot exhaust gases will be introduced by the nipples 9, it, ii'and it into theexhaust gas passageway ligand will travel through this pas-' 'sageway until they are discharged'through the nipple ii which maybe connected to a suitable muffler. The fuel mixture. will be introduced through the port ll into the passageway It and will be gas'ifled before it is discharged through the nipples it,- it and it into the cylinders of' the motor;. a e I As shown in-Fig. 4, the web it has horizontal portions lt at the points where the intake ports as are located, and these horizontal portions are positioned about mid-May between thetop and bottom of the-casting to facilitate manufacture.
f NVhile I have disclosed what I now consider to;
be a preferred embodiment ofthe invention in such manner that it may be readily understood by those skilled in the art, I am aware that changes may be made in the details disclosed without departing from the spirit of the invention as'expressed in the claim. v
What I claim and desire to secure by Letters Patent is:
A combination manifold comprising an elongated hollow casting of substantially box section having a top member, a bottom member, side' walls and ends a web of less length than the casting arranged jwithin the same and connecting one of said members to one of the side walls, transverse webs positioned within the casting and rigidly united with the ends of the first-mentioned web, said webs dividing the interior of the casting into segregated intake and exhaust gas pas-. sageways, an exhaust gas conduit extending through the intake passageway and having its ends connected to the transverse webs and communicating with the exhaust gas passageway, in-
take nipples projecting from the first-mentioned web through the opposite side wall of the cast-.
ing for leading a heated explosive mixture from the intake passageway, a port for introducing an explosive mixture into said intake passageway, other nipples projecting from the last-mentioned side wall of the casting for introducing hot exhaust gases into the exhaust gas passageway, some of said last-mentioned nipples leading into the exhaust gas passageway at points between the transverse webs and the ends of the casting, and others of the last-mentioned nipples being arranged to direct hot exhaust gases against the firstmentioned web, and means for discharging exhaust gases from the exhaust gas passageway.
