To all whom 'it may concern:-

lBe itAv known that l, yWAsHiNG'roN I. PHIIER, a citizen .of the United States of America, residing at Collinsville, in the county of Madison and State of Hlinols, have'invented certain new and useful llmprovements in Engines, of'which tlie f ollowing is a full, clear, and exact description, reference being` had to the accompanying drawings, forming part'of this speciiication.

This invention `relates to engines havin istons reciprocable under pressure derive rom any suitable duid which is introduced into cylinders within which said pistons are operated, and has for its primary object to provide an improved construction, ycombination and arrangement of parte in devices of this character.

One of the objectsv of this invention is to provide an improved construction according to which an engine of this character may be simply and economically manufactured and rendered durable and ecient in operation.

Other and further objectswill appear in the specication andbe specically pointed out in the Aappended claims, reference being had to the accompanying drawings exemplifying the invention and in which, Figure .l is a longitudinal section through my engine. Fig. Il is a vertical cross section taken on line H--L Fig. l. Fig. lll is aside elevation of the cam wheel carried by the engine shaft. Fig. llV is an edge view of the cam wheel. Fig. V is a cross section through the cam wheel, taken on lines V--V, Figs. HI and lV.

inasmuch as my engine is designed to be operated by Huid motivepower of diil'erent descriptions either in the nature of an explosive agent, or steam, for example, l do not in the accompanying drawings show means for delivering. the motive power to the cylinders of the engine, nor the valves or other ap urtenancesv b which the dei livery. andischarge of t e motive power to and from the engine is controlled. Such elements may be an of those ordinarily used, as will be readi y appreciated upon an understanding of the vice to which my invention relates.

ln the drawings: l designates Athe shell of'niy engine, this; shell being closed at its ends by cylinder heads 2, thniagh which the motive power to be used in the engine is admitted and discharged.

Patente ct. i7, i911.

3 designates cylinders arranged in batterf ies within the shell l at the ends thereof, and which abut against the cylinder heads 2, one battery of cylinders appearing most clearly in Fig. lll, while the location of the cylinders longitudinally of the shell is shown in Fig. I. The cylinders in each battery are parallel with each other, and are connected by spider arms 4 extending radially from a central: hub 5. around the cylinders, which are separated from each other, as seen in Fig. Il, is closed at the outer end of each battery by thead-` jacent head 2, and such space is closed at the inner end of each battery by a suitable wall, thereby providing a `water jacket chamber A, making it possible to prevent,

overheating of Athe cylinders in which pistons operate, as will hereinafter more fully Y appear. Each cylinder 3 of the engine is closed at its outer end, except for inlet and exit ports, by the adjacent head 2, while thev inner ends of the cylinders are in open com-J munication with a central chamber B.

6 designates pistons operable in the cylinders 3 and movable through the open inner ends of said cylinders. '-'lhese pistons are arrangedin pairs longitudinally of the engine so that a piston in one of the batteries mates with a piston of the other battery, and the airs of pistons are united Iby'connecting ars 7, each of' which is supplied with an anti-friction roller 8.

9 designates a shaft extending longitudinally df the engine, and rotatably fitted in the shell heads 2 and, the hubs 5 disposed centrally of the batteries of cylinders. rlhis shaft extends through the central chamber B and it has fixed to it a cam wheel 10. The cam wheel 10 is disposed diagonally of the shaft 9 so that during its rotation its side face will, at different points, approach and recede from the inner ends of the cylinders 3. In the riinofthe cam wheel is a helical runway. 1l in which the anti-friction rollers 8, carried by the piston connecting bars 7, operate.

In the practical use of my engine, the pis-- tons u on their forward strokes carr `with them .the connecting bars 7, uniting t epistons in pairs longitudinally of the engine, and during such ibrward strokes of the pistons, the anti-friction rollers 8 by bearing the roller naturally tends to move in the direction of recession of such runway wall. And it is due to this fact that power is transmitted from a piston to the cam and the shaft carrying it. It is obvious that while any given'piston is operating in the manner stated to drive the cam on the engine shaft, the piston mating with the drive piston works idly during its backward stroke in so far as power action by the shaft is concerned, and it will be apparent that when the idle piston has completed its backwardy stroke, it is ready in its turn to perform the oince of imparting a reverse movement to the connectin bar 7 attached to it for the operation of the cam 10 in the same manner as such oiiice was previously performed b the iston at the other end of the engine. I pre er to employ six cylinders and six pistons in each battery of such pistons and -cylinders, this being the number illustrated in the drawings, but it is evident that the number of cylinders and pistons may be other than that shown without departing from my invention.

The essential characteristic features in my engine in so far as the operation of the engine shaft bythe pistons is concerned, are the provision of the cam wheel on the engine "shaft having a runway or track-way face arranged obliquely relative to the shaft, and means to which power is communicated in the operation of one or more pistons to the runway or track surface to -cause rotation of the cam wheel and engine shaft by travel of the means referred to along the runway or track surface.

The chamber B in my engine, in which the cam 10 operates, is intended to be supplied with a quantity of oil in which the cam moves during its rotation. The oil present in this chamber is continually agitated by the cam, and as a result of a limited degree of heat radiating rfrom the cylinders, the o'il is in a measure vaporized so that it will be rendered a most perfect lubricant which is constantly delivered to the working parts of the engine operating in the chamber B.y

This lubricant, upon being caught by the pistons, is transferred from them to the interiors of the cylinders 3 withoutthere being any Waste of lubricant, and without any opportunity of mixture of dirt or foreign matter W-ith such lubricant. Moreover, the presence of the oil bath. in chamber B,

ing of the cylinders and the pistons operatv ing in them, and I make use of Water delivered into these chambers for swabbing the interior walls of the cylinders upon each stroke of the piston, by producing in the walls ofthe cylinders, ducts 12 (see Fig. I), that lead to the interiors of the cylinders, and provide the pistons with annulargrooves 6 that receive water from said ducts when the grooves are brought intoregistration therewith. In this manner, rings of water are caused to be constantly present in the annular groovesl in the pistons,l which act with cooling effect upon thevinterna'l faces of the cylinders, assisting in lubrication of such faces, and further serve asrpacking rings between the pistons and the internal faces of the cylinders.

The herein described construction and arrangement of parts, adapts the engine to develop a maximum amount of power by reason of the large leverage of action upon the engine shaft, due to the connecting bars 7 being disposed on the walls of the pistons farthest from the engine shaft, with the periphery of the cam 9 running between the oppositely disposed pistons.

I claim: g

l. In an engine, the combination with an outer shell, of batteries of cylinders disposed at opposite ends of said shell with an oil containing space between said batteries, a shaft rotatable on an axis centrally disposed with respect to said cylinders, a cam eyed to said shaft in said oil space, said cam having its outer periphery extending around said shaft in a plane inclined thereto and the outer peripheral face of said cam being provided with a runway, a hollow cylindrical piston reciprocable in each c linder, a connecting member for each pair of oppositely disposed pistons, said member being secured to the inner cylindrical walls of said pistons, and an antifriction roller carried by said connecting member and running into said runway.
