MANIFOLDING SYSTEM FOR INTERNAL COMBUSTION ENGINES Filed May 23, 1930 2 Sheets-Sheet 2 v u ATTORNEYS.

Patented Jan. 5, 1932 UNITED STATES PATENT OFFICE ROBERT W. A. BREWER, F JENKINTOWN, PENNSYLVANIA Application filed May 23,

My invention relates to a novel construction of manifolding system for internal combustion engines, wherein I effect in a novel manner the distribution of the explosive mixture to banks of cylinders remote from one another and supplied by one central carbureter or by a multiplicity of carburetors.

To the above ends, my invention consists of a novel substantially rin -shaped inani-' fold or arrangement of passages positioned sage surrounding the crank case and supplied with explosive vapour. a

It further consists of a novel collocation of a crank case, a manifolding system surrounding said crank case, and a novel ar- 5 rangement of junctions therefor.

For the purpose of illustrating my inven tion I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrument alities of which my invention consists can be variously arranged and organized and that my invenr tion is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

In the drawings:

Fig. 1, represents a side elevation of a manifolding system embodying my invention;

Fig. 2, represents a side elevation of Fig. 1, view-ed from the opposite side;

' Fig. 3, represents on an enlarged scale a d vertical section on line 3-3 of Fig. 1, certain parts being shown in elevation.

Referring to the drawings, 1 designates an internal combustion engine comprising more than one bank of cylinders and having a body or block 2 equipped with my novel 1930. Serial No. 454,948.

manifolding system, wherein 3 designates the centrally disposed crank shaft bearing 'for the crank shaft 4, to the end 5 of which the propeller is secured. The engine portrayed in the present instance is of the eight cylinder type having four upper cylinders 6 opposed to four lower cylinders 7, but the number of cylinders can obviously be increased if desired. The carbureter 8 conducts the fuel into the chamber 9, which leads into the horizontal and vertical passages 10 and 11. The passage 10 leads into the chamber 12 which discharges through the upright passage 13 into the manifold 14, which discharges at the points 15 into the upper bank of cylinders 6. 16 designates a vertical passage leading from the chamber 12 to the chamber 17 from which the horizontal passage 18 leads to the chamber 19, into which the vertical passage 11 also discharges. 20 designates a passage leading from the chamber 19 to the manifold 21, which discharges at the points into the lower bank of cylinders 7. The

chambers

12 and 17 are closed by the

plates

23 and 24 respectively, and the chamber 19 is closed by the plate 25. The chamber 17 is also accessible through the bottom plate 26, and the chamber 9 is accessible through the top plate 27.

It will be seen from the foregoing that I am enabled to effect a suitable distribution of the explosive mixture to banks of cylinders remote from one another, and supplied by one central carburetor or a multiplicity of carburetors, by a substantially ring-shaped manifold of symmetrical design composed of the

passages

10, 11, 18, and 16 and their connecting chambers or junctions, positioned around the crank case, and in the ease of the eight cylinder engine, being provided with four junctions at either one of which locations explosive mixtures can be fed into the ring.

My novel arrangement further provides a very convenient means for local heating if desired by passing the vapour passages through the crank case or for the fitting of a vaporizer operated by exhaust heat. It will further be apparent that the banks of cylinders are symmetrically disposed adjacent to the crank case and that the inlet manifolds the various elements hereinbefore referred to,

' be symmetrically arranged with respect to the banks of cyhnders and to each other, all

of which I have accomplished by my novel devices. Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a manifolding system for internal combustion engines, a crank case, a continuous ring-shaped passage for the explosive mixture surrounding said crank case, and a plurality of junctions for said passage at each one of which junctions means are provided for attaching explosive mixture introducing means.

thereto, inlet manifolds attached to opposite sides of said cylinders, a ring-shaped passage for the explosive mixture surrounding sald crank case, a. plurality of symmetrically arranged junctions in said passage, closures for said junctions, and oppositely located symmetrically arranged connections leading from opposite junctions to said manifolds.

In an internal combustion engine, com- -means at said openings for the admission of air and local fuel.
