INTERNAL-COMBUSTION ENGINE.
Application filed June 9,1924. Ser ia1,No. 718,838.
My invention relates generally to internal combustion engines and more particularly to the construction of cylinders and cylinder head for the particular type of engine that forms the subject matter of my co-pending application for U. S. Patent, filed April 17 1924, Ser. No. 707,103. i
The principal objects of my present inven-' tion are, to provide relatively simple and 9 practical construction wherein the two cylinders and head therefor, are separately formed. thereby eliminating the time, labor and expenseinvolved in the production of the complicated patterns, cores and the like that are required, where the cylinders and head are integrally formed; to provide a construction that will enable the cylinders and head to be readily bored machined and finished and. further, to provide an engine cylinder and head arrangement that will greatly facilitate the assembly, or taking apart of the members forming the engine block or body. i
A further object of my invention is to provide each of the separately-formed cylinders and head with a set of fins and to arrange the latter so as to utilize to the greatest advantage the blasts of air that are directed over said fins for the purpose of disseminating the heat developed within the combustion chambers of the cylinders during engine operation.
With the foregoing and other ob ects in view, my invention consists in certain novel features of construction and arrangement of parts that will be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which Fig. 1 is a top plan view of a pair of engine cylinders and cylinder head as contemplated by my invention.
Fig. 2 is a vertical section taken on the line 22 of Fig. 1.
Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 2.
Referring by numerals to the accompanying drawings, 10 designates a separately formed combustion cylinder, the internal working surface of which is of the same diameter throughout its length and formed integral with the upper portion of said cylinder and eXteriorly thereof, is a series of circumferentially arranged heat radiating fins 11.
cylinder and provides a bearing and point of attachment for the cylinder head as hereinafter more fully described.
Formed on the lower end of the cylinder is a flange 13 that is adapted to rest directly upon and be secured to the upper portion of a crank case (not shown).
A two diameter cylinder 14 having a comblnat'ion chamber 15 n 1ts upper portion and a gaseous fuel pumping or precompression chamber 16 1n 1ts lower portlon is formed in a single piece and formed integral with the upper portion of said cylinder 14 or that portion that encloses the combustion chamber is a series of externally ar ranged circumferentially disposed heat radi- 'ating' fins l7.
The internal diameter of combustion chamber 15 and which-is the same throughout its length is somewhat less than the internal diameter of the pumping or precompression chamber 16 and formed through the wall of the cylinder 14, just above the annular shoulder 18 between the chambers 15 and 16 is a series of gaseous fuel inlet ports 19.
Formed integral with cylinder 14, just below shoulder 18, is a laterally projecting tubular member 20 that serves as a gaseous fuel duct.
Formed integral with the upper end of cylinder 14 is an outwardly projecting flange 21 that serves as a bearing and point of attachment for the cylinder head and formed integral with the lower end of said cylinder is a flange 22 that is adapted to rest upon and be directly connected to the upper portion of a crank case.
The head for the cylinders 10 and 14 coinprises a plate or block 23 of proper size and shape to fit upon the head ends of said cylind-zr i0 and combustion chamber 15. Thus the chamber 25 serves as a common clearance, compression and combustion chamber for the combustion chambers in the cylind rs 10 and 14;
The narrow web or plate 26, that is formed integral with the head block and which eX- tends across the central portion of chamber 25, said web rests directly on the inner portions of the flanges 13 and 21, when the head is properly positioned on the cylinders.
Formed in the end of head block 23 above combustion chamber 15 is a threaded aperture 27 that is adapted to receive a spark plug.
Formed integral with block 23, on the upper surface thereof is a series of longitudinally disposed parallel, heat radiating fins 28. These fins 11 and 17, provide a relatively large area of heat radiating surface and the disposition ofsaid fin is such that practically all of their surfaces are adapted to be impinged by blasts of air from a suitably located fan.
Inasmuch as the two cylinders and head are separately cast or formed, production costs may be minimized and the machining and finishing of the separate parts may be more easily and quickly accomplished than if s id parts were of integral, one-piece structure.
Obviously, minor changes in the size, form and construction of the various parts of my improved internal combustion engine may be made and substituted for those herein described without departing from the spirit of the invention, the scope of which is set forth in the appended claim.
I claim as my invention:
In an internal combustion engine cylinder and head construction, a pair of separately formed cylinders arranged side by side, one cylinder having a straight bore and pro vided in its wall intermediate its ends with a port, a flange on the head end of said cylinder, the other cylinder having a two-diameter bore, the wall of the last mentioned cylinder surrounding'the chamber of smaller diameter being provided near its lower end with a port, which latter is in the same horizontal plane with the port in the straight diameter bore cylinder, a tubular inverted L- shaped member projecting laterally from the upper end of the'larger portion of the twodiameter cylinder, a flange on the head end of the cylinder having the two-diameter bore, a head block secured to the flanges on the head ends of the two cylinders, said head block being provided with a chamber that connects and serves as a common clearance, compression and combustion chamber for head ends of the chambers in the two cylinl ders, heat radiating fins on the cylinder having the straight bore, heat radiating fins on the wall of the second mentioned cylinder around the chamber of smaller diameter and longitudinally disposed parallel heat radiatgig 1fins on the outer surface of the head In testimony whereof I afiix my signature.
