binations of parts as will be hereinafter described and claimed.

In the drawings, Figure l is a side view, and Fig. 2 is a vertical cross section on about line 2-2 of Fig. 1. Fig. 3 is a detail sectional view showing one of the abutments in connection with one of the plates of the piston. Fig. 4 is an enlarged section partly broken away showing the valve mechanism and drawn on the same line as Fig. 2. Fig. 5 is a detail cross section on about line 5-5 of Fig. 2. Fig. 6 is a detail cross section on about line 6 6 of Fig. 4. Fig. 7 is a cross section on about line 77 of Fig. 4. Fig. 8 is a detail view illustrating the connection between the valve plates and the means for operating and adjusting the same. Fig. 9 is a sectional view showing a somewhat different construction whereby to especially adapt the engine for use with gasolene.

, The engine piston A and the abutments B within the casing C may be substantially like those shown in my former patent No. 838,460, dated December 11, 1906. In my present engine, I employ a steam pipe D having branches D and D for conducting the steam to the diametrically opposite inlets d and e. The pipe D may have a suitable throttle d, and valvesare provided for cutting off the steam at the islets so that after the steam has been admitted to the casing the supplyof steam may be cut off so that the steam which has been admitted can operate expansively, thus securing the benefit of the expansion of the steam, and I also make the cut-off valves in two parts in the form of disks overlying each other and having openings which may be adjusted into full register or partially out of register in order to control the amount of steam fed to the engine, and I adjust these valve plates relatively by mechanism which will be presently described, operated from the piston of the machine, so that the feed of steam may be regulated by the speed of the engine.

As shown, the casing G is provided with lateral Wings 0 and 0 whose faces are recessed at C and C to receive the cut-off valves, and cover plates G and G are may be adjusted into full register, or partially, or entirely, out of register by the operation of the devices presently described, said disks operating across their respective inlets a and d and the openings in the valve plates being in position to register at intervals with the said inlets, as will be understood from the drawings.

The cut-off valves are operated from the main shaft H of the engine through the gear H and the pinion H the latter being secured upon the shaft I, whereby the cut-off valve will be operated in correspondence to the speed of the engine, as more fully described I hereinafter.

The valve shaft I is made in sections fitting one within the other, the main section I being tubular and having its bore enlarged at its ends at I and I to receive the spiral sleeves J and J, which are mounted upon the tube K which is movable longitudinally within the main section I of the shaft I, and has a square or other noncircular bore in which fits the rod L, which forms a connection for the governor arms to enable the operation of the tube K which carries the spiral sleeves, as more fully described hereinafter. The main valve sections F and F are keyed upon the ends of the main shaft section I in the manner best illustrated in Fig. 8, in which the said valve plates are shown as having central rectangular openings fitting over correspondingly angular portions at the ends of the shaft section K, so that these valve plates F and Gr turn positively with the shaft section I and have no turning movement independent of the said shaft. The tube J it will be noticed is keyed within the shaft section I, so it turns therewith but may move longitudinally within the shaft section I, and it is provided at its ends with the spiral portions J and J, which turning in spiral bearings in the valve plates G and G, operate to give the said valve plates G and G a turning movement independent of the revolution of said plates with their mating valve plates F and F, which latter turn only with the shaft section I i For convenience in assembling the parts, the spiral portion .T may be integral with the lower end of the tube K or suitably secured thereto, and the upper end of the tube K is preferably threaded as best shown in Figs. 2 and 4, and the spiral portion J is screwed down thereon to proper position, so it may operate within the threaded bearing of the valve plate G in the use of the invention. A governor is provided for moving the tube K longitudinally within the shaft section I, in correspondenceto the speed of the engine. As shown, the governor has balls M connected by arms M with the upper end of the tube K through the medium of the threaded portion .I, and also having arms M connected with a suitable support, shown as the rod L extending through the valve operating shaft and suitably stepped at its lower end as shown in Fig. 2.

In the operation of the described construction, it will be noticed that as the engine begins to speed, the

" relatively to their respective valve plates F and F,

balls M moving outwardly under the impulse of the speed of the engine, will tend to lift the tube K within the valve operating shaft, and through the spirals on the portions J and .l shift the valve plates G and G in such manner as to control and regulate the passage of steam to the engine, and cause the same to slow down, and as the engine slows down, the governor will permit the parts to readjust to feed more steam until the desired balance is secured, which will be maintained in the operation of the engine.

In Fig. 9, the disks 1 and 2 are made to reach to the steam inlets as shown in the said figure, so that in case it is desired to use the engine with gasolene, the disks may be arranged to revolve just outside of the space for the operation of the fluid power in order that the gas may explode in order to secure the desired action of the fluid pressure upon the piston.

I claim:

1. The improvement in rotary engines herein described, comprising the piston and its shaft, a casing having a lateral wing and an inlet, a cover plate fitting over said wing, a cut-off valve turning between said cover plate and wing, and having openings movable into and out of register with the inlet, whereby to admit and cut-off steam, a shaft for operating said cut-olf valve and gearing between the said shaft and the piston shaft, substantially as set forth.
