PATENT OFFICE CARL D. SALISBURY, OF CLEVELAND, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE WINTON ENGINE CORPORATION INTERNAL COMBUSTION ENGINE CONSTRUCTION Application filed February 14, 1930. Serial No. 428,385.
This invention relates to multiple cylinder internal combustion engines of V t pe, of large size and particularly adapted o r marine service. More particularly the invention pertains to the construction and arrangement of certain principal parts of such an engine, namely the water box, crank case, crank shaft and securing means therefor.
The design of these parts in a V type engine presents peculiar difiiculties which are accentuated where the engine is a large one; and it is the object of this invention to provide a novel arrangement thereof improved in simplicity, strength, and adaptability to the necessary adjustments.
The exact nature of this invention together with further objects and advantages thereof will be apparent from the following description taken in connection with the accompanying drawing which is a sectional elevation of an engine constructed according to my invention, indicating in broken lines parts of the engine not particularly pertinent here. v With reference now to the drawing, 1 is the water box and 2 is the crank case of the enme. I g The water box 1 isaone-piececastingadapted to receive and position aipa'ir of angularly disposed rows of cylinders, and provide a cooling water space 3 thereabout, and is generally'in the form of two blocks each carrying its row of cylinders. Two of these cylinders 4 appear in the drawing from which it will be observed that the cylinders are secured at their head ends 5 with the upper water box walls and sealed near their crank ends 6 with the lower water box wall, all as will be familiar-to one skilled in the art. The two water box blocks are joined at their lower portions to form an arched wall 20, and are joined thereabove by a web 7 whereby water communication is had between the two cooling spaces 3.
The crank case 2 is, likewise a one-piece casting generally of U-section with side walls 8 and curved bottom wall 9. The crank case has outwardly extending mounting members 10, and is suitably ribbed and webbed interiorly as indicated to provide the lower bearing halves, as appearsat 11, for
the crank shaft 12 of the engine. A hearing cap '18 cooperates with the lower bearing half 11 to secure the crank shaft 12 which is immediately mounted in the usual bush mg 19.- It will be observed that the lower wall 20 of the water box cooperates with the crank case 2 to provide an enclosure for the space within which the cranks 16 move, this enclosure being generally of circular, or approximately hexagonal, section.
It will be understood that cylinder .heads 13 carrying suitable valves 14 and usual associated parts are mounted upon the two head ends of the water box according to usual practice, such as indicated in dotdas h lines in the drawing. Also, pistons 15 have connection with the crank 16 of the crank shaft 12 by means. of connecting rods 17 as usual.
The assembly of the water box and crank case is secured in a novel manner to distribute and equalize the operating stresses in these parts.
To this end parallel tie-rod means are spaced adjacent the crank shaft on either side thereof. Each tie-rod comprises a low er member 21 extending from the lower part of the crank case above and through the bearing cap 18; and an upper member 22 aligned with the lower member and extending therefrom to-the upper extremity of the water box portion on its side. The adjacent extremities of the tie-rod members are joined by a double nut 23, and the upper and lower extremities of the compound tie-rod means thus formed are provided with nuts 24 and the water box may be tightened upon the crank case by turning down the upper nut 24. Still thereafter the bearing cap 18 may be adjusted by adjustment of the nut 23. Likewise since the tie-rod members are separable by manipulation of the intermediate nut 23, disassembly of the parts may be had in a; minimum of overhead clearance. It will be noted that the tie-rods extend between the cylinders and are arranged approximately in the direction of the reactionof said members, and a nut joining said ary stresses between crank shaft and cylinmembers and providing backing for said der head. bearing cap.
Additional to the tie-rods I provide bolts In testimony whereof I hereby afiix my 26 immediately securing together the water box and crank case along the adjacent side edges of both. Thus the cylinder stresses are transmitted to the crank case on either side of each cylinder, from the upper extremity of the water box on one side and from the lower extremity thereof on the other side. The nuts 23 and bolts 26 are made accessible by the usual hand holes 27 provided with removable covers 28.
What I claim is: V
1. In a V type engine, a one-piece water box adapted to receive and position angularly disposed rows of cylinders, a crank case of U-section arranged to carry the crank shaft of said engine, and parallel tie-rod means spaced adjacent the crank shaft on either side thereof and extending from the upper part of said water box, between the cylinder rows to the lower part of said crank case.
2. In a V type engine, a water box adapted to receive and position angularly disposed rows of cylinders, a crank case of U-section secured to said water box and arranged to carry the engine crank shaft, and means securing together the water box and crank case and comprising bolts securing the parts along their sides and parallel tie-rods spaced adjacent the crank shaft on either side thereof and extending from the upper part of said water box to the lower part of said crank case, whereby operating stresses are distributed and equalized, from the upper extremities of the cylinders to the lower of the crank case and from the lower extremities of the cylinders to the upper of the crank case.
,3. In a V type engine, a water box adapted to receive and position angularly disposed rows of cylinders, a crank case of U-section arranged to carry the engine crank shaft, and tie-rod means adjacent the crank shaft for securing the water box and crank case assembly, said tie-rod means extending from the upper part of said water box to the lower part of said crank case and each comprising 'a pair of aligned members removably secured together within said crank case, whereby diassembly of the parts require a minimum head clearance.
4. In a V type engine, a water box adapted to receive and position angularly disposed rows of cylinders, a crank case of U-section arranged to carry the engine crank shaft, a
crank shaft bearing cap, and tie-rod means adjacent the crank shaft and comprising a lower member extending from the lower part of said crank case above said bearing cap signature.
and an aligned upper member extending from said lower member to the upper part of said water box, nuts at the opposite ends CARL D. SALISBURY.
