the casing sectionsupon the fly wheel and v To all whom it may concern:

Be it known that I, ARTHUR C. HALL, .a citizen of the United States, residing at Fulton, in the county of Oswego and State of New York, have invented certain new and useful Improvements in Engines, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to engines'and has for its primary object to provide means for utilizing the exhaust of the engine as an auxiliary driving medium whereby a combination reciprocating and rotary engine is produced and a maximum of power thus obtained from a minimum fuel consumption.

A further object of the invention resides in the provision of improved means for directing the exhaust from the engine cylinders against a plurality of cupped'blades arranged in the periphery of'the fly or balance wheel of the engine.

Another and more specific object of the invention is to provide a sectional peripheral band or casingwhich is so mounted upon the periphery of the fly wheel that the fullimpact force of the exhaust gases will be expended against the blades mounted in the.

wheel, thereby giving an additional rotary impulse to the engine shaft and materially increasing the Working energy of the engine.

A still further object of the invention is to provide a device of the above character which is simple in construction, strong, du-

rable and eflicient inpractical use and'may be manufactured and applied to the ordinary type of reciprocating engine at a minimum expense.

With the above and other objects in view as will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrangements of the parts, .that I shall hereinafter,

fully describe and claim..

For a full understanding of the invention, reference is to be'had to the following de-. scription and accompanying drawings, in

Figure 1 is a side elevation of anengine showing my improvements applied thereto; Fig. 2 is an enlarged vertical section through the rim of the flywheel and the sectional peripheral band or casing arranged thereon; Fig. 3 is a section taken on the line 3-3 of Fig. 2. Fig. 4: is a detail transverse 6 section illustrating the manner of mounting applying a lubricant to said wheel.

In reciprocating engines of the single or inultiple cylinder type using either gas or steam as the actuating fluid, the larger part of the fluid pressure is expended in moving the reciprocating pistons and in gas engines, the heat of the exploded gases is greatly reduced by the water jacket of the piston cylinder. Much of the power of the actuating fluid is also exhausted to the atmosphere. As above outlined, the purpose of the present invention is to provide means for utilizing this wasted energy and transmitting the same to the engine shaft, so as to materially inc'reasethe working power of the engine without increasing the consumption of fuel.

For convenience in illustration, I have shown the invention applied to an engine of the horizontal single cylinder type, but it will be understood that the invention is also applicable to double or multiple cylinder engines of either the horizontal orvertical type and also to steam or gas engines irrespective of their particular construction.

' With the above end in view I have illustrated one embodiment of my invention in the drawings, wherein 5 designates the engine cylinder and 6 the exhaustport thereof, from whichthe exploded gasor steam is exhausted after the same has acted against the engine piston; To this exhaust port one end of a pipe 7 is connected in any approved manner. The fly or balance wheel 8 is fixed upon the engine shaft 9. The periphery of this fly wheel is provided with a deep annular groove or channel 10, the opposed walls of which are'rabbeted' as indicated at 11, to provide annular shoulders 12. In the shoulders 12 and in the base of the channel 10 the blades or vanes 13 are secured. These blades are bent or curved as clearly shown in Fig. 2, so that the full propulsive effort of the steam or gas in its' impact against these blades will be utilized. Upon the fly wheel a band or casing is arranged. This casing consists of two substantiall semi-circular sections 14, the extremities 0 which are laterally flanged and apertured to receive the connecting bolts 15. The outer surfaces of these casing sections are preferably convex as shown to give a finished appearance to the fly wheel. The upper casing section is centrally provided with a port 16 to which one end of the pipe 7 leading from the exhaust 4 wheel to a minimum.

' the inner end of into which t of the engine is connected. These casing sections loosely en gle upon the spaced annular shoulders 12 0 t e y wheel and suitable 011 cups ,17 are mounted in the upper section 14 to'supply oil to these shoulders and thus reduce friction between the casing and fly The lower casing section 14 is centrally provided with a port 18 which communicates with radually' deepening pocket 19 e gases are discharged from the blades 13 on the-fly wheel. To the port 18, a discharge or exhaust pipe 20 is conn-ected. lVhile the pipes 7 and 20 may be relied uponto maintain the sectional casing sections 14 in a'stat-ionary position with relation to t-hefly wheel, I preferably provide the obliquely disposed braces 21 which are secured to the casing sections adjacent one of their ends and to the respective intake and exhaustpipes. It will of course be understood that If necessary, additional bracing means may be provided for the sectional casing. v I

From the foregoing it is believed that the construction, operation and several advantages of the invention will be clearly understood. I

It will be apparent that the device not only provides eflicient means for greatly inthe end of a creasing the operating efiiciency of the engine but also serves as a muffler for the exaust from the engine cylinder. The exhaust gases acting against the blades 13 on the .fiy wheel serve as an auxiliary driving medium for the engine shaft so that the engine may be operated at greatly increased speed over the ordinary type of reciprocating engine without my device applied thereto, while at the same time the consumption of fuel and consequent operating cost is not increased. Furthermore, it will be apparent that the invention is applicable to all types of reciprocating engines without necessitating any change in the form or arrangement of the working parts thereof. The device maythus be readily'applied in its proper operative position upon the engine at com-v paratively small cost.

-While I have shown and described the I preferred construction and arrangement of' the several elements, it will be obvious that the invention is susceptible of considerable modification without de arting from the essential features or sacrificing any of the advantages thereof.

Having thus described the invention, what is claimed is:

1. The combination with an engine, of a fly wheel for said engine having an annular channel in its periphery and an annular shoulder at each side of the-channel, spaced blades fixed in the walls of said channel, a two-part casing arranged upon the periphery of the fly wheel and loosely engaged upon said annular shoulders, a pipe leadlng from the exhaust of the engine cylinder and connected to said casing to direct the exhausted actuating fluid against the blades on said fly wheel, a discharge pipe connected to to the atmosphere, and brace bars connecting the casing sections to the intake and dis charge pipes.

2. The combination with an engine, of a fly wheel for said engine. provided with a deep annular channel in its periphery and annular shoulders at each side of said channel, a two-part casing arranged upon the periphery of the fly wheel and loosely contact-ing with said shoulders, a plurality of spaced blades fixed in the walls of said channel, a pipe connected to the exhaust of the engine cylinder and to one of the casing sections to direct the exhausted gases from the engine cylinder against the blades of said fly wheel, the other of said casing sections being provided with an outlet port, a discharge pipe connected thereto, the inner wall of said casing section being provided with a gradually deepening pocket to direct the gases from the blades of the fly wheel into the discharge pipe, and obliquely disposed brace bars connecting the respective casing sections to the intake and discharge pipes.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
