INTERNAL-COMBUSTION ENGINE.

Application filed February 9, 1924. Serial No. 691,687.

To all whom it may concern;

Be it known that I, PROSPER LORANGE, a citizen of Germany, and a resident of Mannheim-Freudenheim, Germany, have invented certain new and useful Improvements in Internal-Combustion Engines, of which the following is a specification.

My invention relates to improvements in internal combustion engines, and more particularly in engines which are constructed in such a way that to a large extent the same elements can be used for building right and left engines. Heretofore engines and more particularly marine engines have been constructed in such a way that all the main elements of the engine located at opposite sides of a plane of symmetry located longitudinally of the engine and passing through I the axis thereof are as far as possible alike in form, and that other parts which distinguish the right and left sides of the engine are mounted and shaped so that one may take the place of the other. Invconstructing on this principle for example a marine Diesel engineconsiderable difficulty is connected with the construction of the base plate having at one side the driving means for the cam shaft mounted thereon. But it is possible to. construct the base plate on the above principle, though a base plate is obtained which is less simple in construction. However, the construction of the frame and more particularly the uprights is more difficult particularly where the uprights have the guide ways for the cross head, driving means for compressors V and ship freeing and pumps, and means for V cooling the pistons mounted thereon, in which case the construction must be such that each of these parts can be fixed either to one or the other side, and it is necessary to provide the uprights at both sides with fitting faces and screw bolts.

,The difliculty in the construction is fur: ther increased in cylinders which are provided at one side with the cam shaft and at the opposite sidewith the exhaust and ad mission pipes, in which case the cylinders must be constructed in such a way that they can be individually turned around. But even when so constructing the cylinders there remain difficulties which are almost unsurmountable.

In any case, where the engine has been constructed so as to be symmetrical relatively to the said longitudinal plane, it can not be changed from a right to a left engine Without practically reconstructing the engine and subjecting the same to a new trial.

The object of the present invention is to provide an engine the elements of which may be completely manufactured and kept in stock and combined at will into a right or left engine. With this object in View I do not rely on the said symmetry relatively to alongitudinal plane, but I construct the engine symmetrically of a transverse plane, in which case there are only a few non-corresponding parts at the front and rear end, which parts can be readily exchanged.

For the purposerof explaining the invention an example embodying the same has been shown in the accompanying drawing, in which v i Fig. 1 is a partially diagrammatic'side elevation of an engine; Fig. 2 is a lan View of the engine shown in Fig. 1; ig. 3 is a view similar to Fig. 2 but showing. the

engine turned about through an angle of' 180 and theinterchangeable auxiliary connections thereto reversed in position; and

Fig. 4 is an end elevation of the engine shown in Figs. 1 and 2 as seen from the left hand end thereof.

As shown in the drawings the cylinder casting and basevplate o is constructed symmetrically relatively to the central transverse plane indicated by the center lines uv in Fig. 1 and w-y in Figs. 2'and 3.

Secured to the top of the cylinders is the cylinder head castin or ho lsing cl which carries, in an extension pro ect1ng laterally from one side thereof, the bearin s for the camshaft c; said cam shaft being riven from the main or crank shaft of the engine by means of the gearin a, vertical shaft 6 and bevel gearing b which is located within the gear casing at the top of said vertical shaft. j

Projecting laterally from the side of housing (l opposite to the cam shaft e is the exhaust manifold is having its branches Z leading to and communicating with the cylinders. The cooling water for the cylinders is supplied through a manifold m, the branches 1:. of which lead to the hollow cylinder walls between the upper and lowor ends thereof, said manifold m projecting head 0!.

laterally from the side of the .cylinders and being located below the manifold is as clear- 1}) of said manifold extending upwardly at an angle and leading throughthe cylinder head or housing (1. The cooling water is withdrawn from the engine through the manifold g, the branches 1- of which lead to and are connected with the cylinder Each-of the end standards 6 is provided with a hearing or seating surface to'which the valve regulator k may beinterchangeably connect-ed. In addition to the seating sur ces provided for of the end Walls of also provided with a seating surface to pump 9 may be interchange- Both ends of the crank shaft the gear casing a, each ably secured.

are provided with a disk or flange t which serves for connecting the flywheel .sto said shaft, or for the connection of, said shaft to the driven shaft.

In order to change the engine. from a right hand to a left hand arrangement 'it is only necessary to turn the engine about its vertical axis or center line and to change the parts a, b and f for driving the cam shaft, and the fuel pump gfrom one end wall of the thereof, and to also change the valve reguthe cylinder casting is engine to the other end Walllator /The interchanging of these parts can be accompli'shed very readil without involving the necessity for re-ad uSting the conductingnew' trialsof the engine.

of the engine are. disposed symmetrically with respect'to a median transverse plane and that corresponding fitting or seating faces a're'provided at'each end of the engine for the interchangeable elements.

I claim:

A vertical internal combustion having a number of fixed elements there- 'of disposed symmetrically ontboth sides qfa median plane extending transversely said engine, said engine being provided It will be noted that the'fixedfelements of at its front and rear ends with similar fitting faces and a plurality of diverse elements adapted to be interchangeably secured to the corresponding fitting faces provided at each end of said engine, whereby said ehgine may he changed from a right hand to a left hand engine or vice versa by rotating it through an angle of 180 about its central vertical axis and changing said diverse elements from the fitting faces provided at one end of the engine to the corresponding fitting faces at the other end thereof. a
