UNITED STATES CHARLES REINEKE, 0F NFUTV YORK, N. Y.

IN'rEaNAL-comBUsTioN ENGINE Application med Dctober 1. 1920. Serial N. 414,048.

To all whom it may com/ccm.'

Be it known that I, CHARLES RnrNnxE, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Internal- Combustion Engines; and I do hereby declare the following to be a full, clear, and exact description V'ofthe invention, such as will enable others skilled in the art to which it appertains-to make and use the same.

This invention relates to internal com-. bustion engines, and more particularly to the type of multi-stroke engine set forth in my co-pending application Serial Number 396,902,61edJu1y 17, 1920.

An object of the present invention is to produce a novel'power transmitting mechanism wherein the reciprocating movement of the pistons is converted into a relatively slow rotary movement by the interpositioning of gearing.-

Another object of this invention is the production of a multi-stroke internal combustion engine in which the yrelatively rapid reciprocating movement of the pistons is transmitted to a power shafty in a smooth and positive manner and without the interpositioning of the usual crank.

A further object of the invention is tov produce a multi-stroke engine having opposed pistons and means for synchronizing the movements of opposite pistons in adjacent cylinders .for evenly transmitting the power from said piston to a relatively slow moving shaft.

A further object of the invention is to provide a simple and easily constructed engine wherein advantages of assembling, re pair and low cost of production are important factors.

With these and other objects Ain view my invention further consists in the construction and arrangement of the several parts hereinafter described and pointed out in u the appended claims.

In the accompanying drawings, in which corresponding reference characters designate similar parts in the several views:

Figure 1 is a vertical sectional view through my.- improved engine;

Figure 2 is a vertical transverse sectional view;

Figure 3 is a horizontal sectional View on the line 3 3 of Figure 2; and

Figure 4 is a fragmentary view illustrating another form of gearing capable of transmitting power.

The present invention has been desi ed with a view to obtaining a. simple and direct transmission of the reciprocatory movement of the pistons to a power shaft. In marine internal combustion engines, for exam le, it is desirable to obtain a relatively s ow speed of the propeller shaft as compared with the' high speed Vpiston travel and to this end I have applied to my multi-stroke motor, a positive form of interconnected gearing for transmitting steady and maximum power. It will be understood, however, that my engine is equally applicable to other uses of either stationary or mobile character, such for example, as heavy duty power generating plants, automobiles and the like. 'It will be further understood that oil, compressed air, steam and other power mediums may be employed, and various other changes made in the design and construction ofmy engine to 'provide for these several' motive agents, and I do not limit myself totheexact disclosures herein shown and described.: t' v Referring to the-drawings, `in which I have shown -for example a two cylinder type of engine, the base 1 may be of any design, to which are secured at 24the cylinders 3.

Operable within the cylinders 3 are opposedA pistons 4 and 5, between which the fuel charge is admitted and red in any` approved manner. The fuel charge may be forced into the cylinders by means of auxiliary. or crank case compression, and any approved type of valve control for theinlet and exhaust'of said charges throu h ports 7 and 8, may be provide as will e understood.

The lower pistons 5 are each provided with freely revolvable' rollers 10 Ydesigned to operate ybetween cooperating arms or wings carried by cam elements 11 and 1 2. Frame sections 9 are connected to the upper piston 4 and are provided with rollers 10 designed to operate between cooperatingarms or wings ofthe cam elements. As shown, each cam element is formed with four arms o r wings, but it will be understood that this number may be varied to increase or decrease the number of strokes of the engine.

In operation it will be seen that as the pistons 4 and 5 are separated, the rollers 10 carried by the lower piston A4 will move or scissor downwardly between the cooperat-in arms of the cam elements 11 and 12; an the rollers carried by the frame sections 9 .connected to the upper pistons will move or scissor upwardly between other of said cam elements, thereby revolving Athe same -in is secured another worm 2O adapted to mesh with a worm gear 21 secured to the main or power shaft 22 of the engine.

The 4shafts 13 are arranged upm each side of the intermediate shaft 14, and are 1 journa-lled in bearings 23 provided on other I cross webs ofthe base 1.

Worms 24are secured to each shaft 13, and are designed to mesh with respective worm gears 25 se'cured to vertically disposed shafts 26. To the ends of the respective shafts 26 are secured other worms 27 which.

worm gears 28" are adapted to mesh with secured to the main or ower shaft 22.'

It will be obvious t at these res ctive sets of separated mechanisms are rig t and left arrangements -of worm gearing interconnected as shown upon opposite sides of the main shaft 422, thereby. serving to evenly balance the thrusts and associated movements of the several parts.

It will also be apparent that the opposite rotation of the cam elements and their supporting shafts is changed by the aforesaid gearing to a single direction of rotation in the main or power shaft 22.

In the form of gearing shown in Figure 4, wherein a series of ordinary spur ears is utilized, the respective shafts 13 an 14 are each provided with a single gear of a different size.4` For example the large gear 29 is secured to the shaft 14, and is adapted to mesh with a. similar gear 30 carried by the' main shaft 22. The associated shaft 13 has secured thereto a relatively smaller gear 31 designed to mesh with an interposed idler gear 32, which latter in turn meshes with a similar gear 34secured to the main shaft 22.

From this construction it will be seen that the opposite rotations of the shafts 13 and 14 are directly converted by this form of interposed gearing' so that the driven main shaft 22 rotates in a single direction.

Any type of mechanism can be connected to the main shaft 22 as will be understood.

The means for synchronizing the opposite pistons .of adjacent cylinders comprises a connection 35 suitably guided in a sleeve 36,

A -worm 16 is secured to the Vlng a single revolution and having-its respective ends connected to' the lower piston 5 in .one cylinder at 37 and the upper' piston 4 in an adjacent cylinder at 38. By `this construction the pistons are kept in timed relation and are prevented from dropping or setting in an uneven manner when the engine is stopped. v

From the foregoing it will be obvious that I have produced a highly eilicient and easily driven motor, the reciprocating piston travel of which i's bot-h. reduced and converted so that relatively low but maximum driving power of the main shaftl is obtained.-
