ROTARY ENGINE.

Specification of Letters Patent.

Patented Oct. 14,1913.

Application filed July 8, 1913. Serial No. 777,839.

To all whom it may concern:

Be it known that we, Jnssnr B. Nnnnnr and ROY E. NEELEY, citizens of the United States, residing at Bighill, in the county of Madison and State of Kentucky, have invented certain new and useful Improvements in Rotary Engines, of which the followin is a specification.

This invention relates to rotary steam engines, and pertains especially to double rotary pistons and means for mounting and operating the pistons.

The object of the invention is to provide a simple and inexpensive construction in a double or compound rotary engine involving novel construction and arrangement of parts.

A further object of the invention is to provide rotary pistons having peripheral steam pockets, with a special ring for dividing the pistons, and with special means against which the pistons revolve and for holding the ring fixed during the rotary movement of the piston.

A still further object of the invention is to provide a specially constructed steam chest in combination with the piston pockets for holding the dividing ring in fixed position during the revolution of the piston.

In the accompanying drawings forming part of this application :Figure 1 is a side elevation of the engine mounted for operation. Fig. 2 is a sectional end view. Fig. 3 is a central vertical sectional view, showing the dividing ring in elevation. Fig. 4 is a sectional View on the dotted line (4-6; Fig. 2. Fig. 5 is a detail perspective view of the dividing ring. Fig. 6 is an enlarged section taken through two pairs of the steam pockets. Fig. 7 is a detail perspective view of the steam chest. Fig. 8 is a top view of the steam chest.

The same reference characters denote the same parts throughout the several views of the drawings.

The engine may be transported to various positions, and therefore, it is preferably mounted on a bed 1, having brackets 2, on which a shaft 3 is journaled. The shaft has a key 2 and is preferably of such length as to permit the engine to be placed or adjusted lengthwise thereon as desired or as occasion may demand, and the engine casing 4 is secured to the bed 1 by means of slotted angle plates 5, which are adjustable on the bed 1 by bolts 6. The sides and the periphery of the casing are secured together by a plurality of bolt-rods 7 The casing is provided with exhaust ports 1.

The double piston is composed of a central hub 8, having disks 9 and 10. The periphery of each disk has steam pockets 12 and 13 respectively, the depth of the pockets alternate in the respective disks, and the piston is securely mounted on the shaft 3, within the casing 4, so as to revolve the shaft in either direction when the piston is under steam pressure.

The steam chest or head 14 is of special design which will now be described in detail. Said chest or head has an inner arc-shaped face 15 against which the piston revolves, an arc-shaped central projection 16 fitting over the hub 8 and between the cylinder disks 9 and 10, flanges 17 provided with bolts 18, slots 19 central of said flanges, and an induction. port 20 in each flange. The head 14 is attached to the casing by means of a pair of plates 21 fitting notches in the periphery of the casing and having the bolts 18 extending therethrough and provided with nuts 22. This arrangement securely fastens the head 14 in proper position and connects the head with the casing. A steam induction pipe 23 is coupled with one of said ports 20, and a like pipe 24 is coupled with the other port, both of said pipes being connected with a steam supply pipe 25, by pipe couplings 26 having suitable valves 27.

In order to separate the piston disks and to revolubly connect the piston with the head 14, a connecting yoke or dividing ring 28 is made to fit the space between the piston disks. Said yoke or ring is in two parts which are hinged together at 29, and the other end of said parts has a shoulder 30 fitting against the inner face of the flanges 1 7, and said shouldered ends have an ear 31, projecting therefrom and fitting the slots 19, and said ears are secured in the slots by suitable means such as pins 32. It will be seen that the ring or yoke not only divides the piston but said ring divides the easing into two separate and independent compartments for the piston disks, and that the piston is revolved in the ring.

Obviously the head projection 16 and the yoke or ring centralizes the piston with respect to the head 14, and the head being secured to the casing permits the piston to be revolved in either direction according to the induction of steam through either one or the other of the pipes 23 and 24, by operating the valves 27.

We do not wish to be understood as confining the invention to any particular size or material, nor for any particular purpose, neither do we limit ourselves in the location of the steam chest or head, as it may be changed to any part of the periphery of the casing with the same results, but we reserve the right to make such variations in construction and arrangement of parts in the practical construction and operation of the engine as may come within the scope of the appended claims without departing from the spirit of the invention.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is 1. In a rotary engine, the combination with a shaft, a fixed casing, and means upon which the shaft and the casing are mounted, of a double piston secured to the shaft within the casing, and having reverse pockets, a steam chest head secured to the casing and having steam ports leading to the pockets for revolving the piston in either direction, and means connecting the head with the piston for centralizing the latter with the head.

2. In a rotary engine, the combination with a shaft, a fixed casing, and means upon which the shaft and the casing are mounted, of a piston secured to the shaft within the casing and having two sets of pockets, a steam chest head secured to the casing and having steam ports leading to the respective pockets for revolving the piston in either direction, and a yoke secured to and depending from the head between the sets of pockets so as to divide the piston centrally and to centralize the piston with the head.

8. In a rotary engine, the combination with a shaft, a fixed casing and means upon which the shaft and the casing are mounted, of a piston having a central hub and a set of peripheral pockets on each side of the hub, a steam chest head secured to the periphery of the casing and having a projection fitting the hub space between the sets of pockets, and a yoke secured to the head so as to permit the hub to revolve in the yoke.

4. In a rotary engine, the combination with a casing, a piston revoluble in the casing and having a central hub, and a set of steam pockets in the periphery of the piston on each side of the hub, of a steam chest head secured to the periphery of the casing in contact with the piston and having steam ports leading to the pockets, and means for revolubly hanging the piston from the head comprising a yoke secured to the head and extending around the piston hub.

5. In a rotary engine, the combination with a pocketed piston having a central hub, and a fixed casing for the piston, of a steam chest head having flanges secured to the casing, induction pipes secured to and discharging through the flanges into the pockets for revolving the piston in both directions, and a yoke extending around the hub and secured to the said flanges for connecting the piston with the head.

6. In a rotary engine, the combination with a pocketed piston having a central hub, and a fixed casing for the piston, of a steam chest head having flanges secured to the casing, induction pipes secured to and discharging through the flanges into the pocks0 ets for revolving the piston in both directions, and a hinged yoke extending around the hub and having ears secured to the flanges.

In witness whereof we hereunto set our hands in the presence of two witnesses.
