ENGINE.

raeaeeo.

To allwhom it may concern v Be it known that I, FRANK A. HILL, a citizen of the United States, residing at Rock Island, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Engines;

and I do hereby declare thefollowing'to be a full, clear, and exact description 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 engines, and more particularly to those of the internal combustion type.

The invention has for its object to pro vide means for utilizing the heat of the internal combustion engine in the production of steam to be conveyed to one side of the piston of'the engine to increase the power thereof. I v

With these and other objects in view, the

invention consists in the novel construction,

arrangement andformation of parts as will be hereinafter specifically described, claimed and illustrated in the-accompanying drawing, inwhich the figure represents a sectional view, partly broken away, through an engine constructed in accordance with this invention.

Referring to the drawing in detail the numeral indicates the cylinder of the engine,

which is formed with a plurality of external fins or flanges 6. A piston 7 is reciprocable longitudinally within the cylinder 5 and carries the piston rod 8 slidably mounted through the closed end 9 of the cylinder. .The opposite end or head of the cylinder is provided with intake and exhaust ports 10 and 11 respectively adapted to admit combustible gas to the explosion chamber 12 of the cylinder and to permit of the exhaust of the products of combustion. The

dome 18 is connected with a steam pipe 19 extending through the wall of the boiler 17 and communicating with the cylinder 5 on the side of the piston 7 opposite the explosion chamber 12. The steam admitted to Specification of Letters Patent.

Serial No. 869,687.

the chamber 20 of the cylinder 5 is controlled by a mechanically operated valve 21.

The water or other fluid within the boiler 17 is heated by the cylinder 5 and its flanges 6 when theengine is being operated by internal combustion of a suitable fuel. The exhaust port 11 for the explosion chamber 12 is connected with a header 22 in which is secured a plurality of pipes 23 which are coiled about the cylinder in spaced relation to the latter and to the boiler 17 and are connected at their opposite extremities with a pipe 24: extending through the lower portion of the boiler 17 and connecting the pipes 23 with a hollow drum 25 from which the products of combustion pass into the final exhaust pipe 26.

The escape of steam from the chamber 20 is controlled by a valve 27 connecting said chamber with a. pipe 28. The lower extremity of the pipe 28 is connected with an approved type of condenser 29, preferably provided with pipes 30 for conducting a relatively cool fluid to the condenser to assist in condensing the steam exhausted during the operation of the'engine. The con denser 29 connects with a centrifugal pump 31 by a pipe 32, and by means of said pump the'condensed steam is returned to the boiler 17 through a pipe 32. The pump 31 is provided with the usual shaft 33 adapted to be connected with any suitable driving means. The pipe is extended longitudinally through the heating drum 25 and that portion thereof which is disposed within said drum is indicated at 34.

The heating of the liquid Within the boiler 17 is materially assisted by the coiled pipes 23-through which the heated products of combustion from the explosion chamber 12 are conducted to'the drum 25. 2 It is also evident that the liquid in returning to the-boiler 17 through the' ciosing said cylinder, a plurality of pipes connected with said exhaust port coiled about said'cylinder and extending through the Wallof said boiler, a hollow drum connected with the outer extremities of said pipes, a dome carriedby said boiler, a pipe connecting-said dome with the closed endof said cylindeiya valve in said pipe, a eondenser, a'pipe connecting the closed end of said cylinder With said condenser, apipe connecting said condenser With said boiler and, extending through said hollow drum, and a pump connected with the last mentioned pipe for returning the condensed steam to said boiler.
