Rvilmlg? IN ROTARY -STEAM-EANGINS 'rhe schedule referme m me maar Patent and making pm of me sans.

To all whom 1t may concern:

Be it known that I, LEvI F. GOBN, of Spring Hill, in the county of Livingston, and State of Missouri, have invented'a new and useful Improvement in Rotary Engines; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable. othersskilled in the art to make and use the saine, reference being had to the accompanying drawings, forming part of this specification.

This-invention relates to vcertain improvements in what are known as rotary engines, and'it consists in the construction and arrangement of parts as hereinafter described.

Figure 1 is a sectional end elevation of showing the operating parts.

. Figure 2 is a. vertical section' of iig. 1, through the' line n: z.

Figure 3 is an outsitleview'of the engine.v

Similar letters of reference indicate corresponding the en'gine,

A is a. central cylinder,A which passes directl through the centre of the engine. Thiscylinder has wo longitudinal cavities or channels in its outer surface, into which the pistons on other revolving cylinders enter as they revolve.

B represents four piston-cylinders, which revolve in' contact with the cylinder A, the surface of which cylinder A forms a point of resistance to the stea'm when the engine is in motion.

; C represents the pistons on the cylinder B.

Each ofthe cylinders B operates in a steam-chamber, I), as rscen in the drawing.` The steam is admitted into these cylinders through the ports e, andsexhausted after the cylinder has made its revolution through the ports and out through the side of the engine.

The' steam-ports e are in communication witha hollow cut-off valve, which iaoperated by a crank,-g. h The revolution of the valve corresponds with' that of the cylinders B, so that the ports e receive steam at the right time to act upon the pistons. j

I is-the steamfpipe, and J is the exhaust-pipe.

The cylinders B, and the central cylinder A, are con-v n'ected together by gearing on the 'side of the engine, as seen at K, so that the power 'of the steam on the cylinders B is imparted to the central cylinder thereby.

They are also connected at the other side of the engine byarrns ''a'nd the crank g',"a's'seen in the drawing.

It will be seen that the steam acts continuously on the pistons, and that there is no loss of power from deadcentres. f

Having thus described my invention,

What I claim as ters Patent, is-

1. The construction of the central cylinder, A, with longitudinal channels adapted to receive the pistons C of the cylinders B, substantially as herein shown and described.`

2. The steam-chambers D, having ports e j, and adapted to' receive the cylinders B, provided with pistons C, substantially as herein shown and described.

3. The combination of the central cylinder, having longitudinal grooves, the cylinders B, provided with pistons O, and the steam-chambers D, with ports cj; all arranged within the case A, to operate substantially as described. y i

4.' The means for operating the cut-olf valve, conl sisting of the arms n n and crank g, all arranged to operate substantially 4as herein shown' and described.

The above specification of my invention signed by me, this 20th day of April, 1868.
