INTERNAL-COMBUSTION ENGINE.

namens.

To ali 'ib/'tom i may concern: I y Be it known that I, HENRI Vieron JULES Jourrnnr, engineer, citizen of the French Republic, residing at Paris, France, have invented certaing' 'new and useful Improvements in Internal-Combustion Engines, of which the following is a specification.

`This invention relates to motors of the type in which the crank shaft'is connected by a system of gearing tothe driven shaft and refers more particularly, among motors of the class in question, to those having cylinders arranged in the form of a V, in

" u cylinders.

the vcase of which the driven *shaft is located parallel to the crankshaft and between the two arms ofy the' 1' lt has for its principal object to enable motors of the class in question to be so con-` structed that the transmission of power from the crank shaft to the driven shaft vis effected more satisfactorily than is at-present the case.

It consists essentially in providing motors of the class in question with a crank shaft..

made in two parts placed end to end and in interconnecting them by means of a sleeve so constructed and arranged that the said sleeve constitutes one o'f the elements of the transmission gear between the crank shaft and the driven shaft. y

The invention comprises in' -addition to this principalfeature certain other features which will be more fully described hereafter.

It includes, in particular, certain constructions embodying the said features, and it includes, as new industrial products, mo-

tors of the class in question comprising the application of the said improvements, as well as special parts adapted for their construction.

t will be clearly understood with the assistance of the following description and fromthe accompanying drawings which, however, are given merely by way of example.

Figure l of the Said drawings shows, in

longitudinal section, a motor constructed ac-- cording to the said invention.

Fig. 2 shows the same motor in transverse section on the line Q-2, Fig. l.

The motor more particularly illustrated in the drawing comprises 16 cylinders, having the cylinders arranged in V formation the driven shaft being driven from the crank Specification of Letters Patent.

The general construction `and arrangement ofthe cylinders ofthe motorland'the valvemechanisni is of the ordinary descrip tion, but the cylinders are 'divided into two Patented oet. a, 191e.

The adjacent extremities of the two parts b and b1 constituting the crank shaft, are

interconnected by a sleeve d which is keyed to each of the said eXtrem-iies.

The said sleeve d is provided at the middle.

with a pinion do.

- On the axle c to be driven is provided a toothed wheel co engagingwith the toothed pinion do.

The casing that the'parts of the crank shaft, the sleeve l and thetoothed wheel co can be easily placed in position. It may for instance, be madein three portions, a lower portion, a middle portion and an upper portion.

The foregoing details of construction are sufficient foi` a practical engine but it is of the motor is constructed so i preferable to combine with them the whole y the bearings c, and@1 and forsimultaneously effecting the clamping of the bearings c and f and of the bearings el and f1 bolts g are used common to both.

The adjacent parts of the two pieces t and 1 of the driving' shaft are formed as truncated cones, decreasing in section t0- ward the extremities, and in order to insure the clamping of the sleeve d on these truncated parts, a screw threaded pin z is pro- I shaft transmits its effort directly tothegear each of said parts, a

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed I declare that what I claim is: 1. In a motor of the character described, in combination, a divided driving shaft comprising two alined parts, bearings for driven shaft, and gearing connecting said driving and driven shafts and'including a sleeve connecting the contiguous ends of the parts of said driving shaft, the extremities of said sleeve being journaled in the adjacent driving shaft bearings.

2. In a in combination, a divided "driving shaft Comprising two'alined parts, a driven shaft, bearings therefor, gearing connecting said driving and driven shafts and including;l a sleeve connecting the contiguous ends of the parts ofV said driving shaft, supports for the extremities of said sleeve, and bolts connecting said driven shaft bearings and sleeve supports.

3. In a motor of the character described, in combination, a divided driving shaft comprising two alined parts, bearings for each of said parts, a driven shaft, bearings for said driven shaft,gearing connecting said driving and driven shafts and including a sleeve connecting the contiguous ends of the parts of said driving shaft, the extremities of said sleeve being journaled in the adjacent driving shaft bearings, and bolts connecting said driven shaft bearings with said last-named driving shaft bearings'.
