STEAM-ENGINE.

SPECIFICATION forming part of Letters Patent No. 409,155, dated August 13, 1889.

Application filed March 18, 1889. Serial No. 303,687. (No model.)

To all whom, it may concern:

Be it known that 1, CHARLES R. DELLEN- BAUCH, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Steam-Engines; and I do declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the IO art to which it appertains to make and use the same.

This invention relates to certain novel improvements in what I denominate automatic hi gh-speed rotary steam-engines, designed as I 5 a motive power for variouskinds of machinery, and especially for such machinery as requires reversal; and the nature of my invention consists in a high-speed reversible rotary engine constructed as will be fully understood from the following description and claims, taken in connection with the annexed drawings, in which-- Figure 1 is a front end elevation of my improved engine complete. Fig. 2 is an eleva- 2 5 tion of the same end of the engine, partly in section, with the head or cap plate and flywheel. Fig. 3 is a side view of Fig. 1. Fig. 4 is a central or diametrical section taken longitudinally through the engine. Fig. 5 is a perspective view of the piston-rin g detached from the engine-cylinder. Fig. 6 is a perspective view of the slotted front inside plate shown in its place in Fig. 4. Figs. '7 and 8 are steam oscillating valves. Fig. 9 is a View of the slotted back inside plate shown in section on Fig. 1. Figs. 10, 11, and 12 show the construction of a bucket or piston-stem and guide. Fig. 13 is a view of the cam-slotted plate which is applied on the rotative engineshaft for actuating the pistons. Fig. 14: is a diametrical section of the piston cylinder or ring, the main shaft, and the spider casting to support this bucket-cylinder. Figs. 15, 16, and. 17 are views of one of the compound pistons, the sectional detail view, Fig. 17, showing the steel springs interposed between the movable yoke and body of the piston. Fig. 18 is a section or part of the main shaft with its keyseat.

Referring to the annexed drawings by letter, A designates the main cylinder of my improved rotary engine; B, the back closed ring head; B, the front closed head thereof; C, the main rotative shaft, with its reduced portion C; D, the ported and valve-boX casting on top 5 5 of the main cylinder, and A the leg or base portion thereof. These parts constitute the main frame of the engine and are constructed substantially as I have represented in the annexed drawings, Figs. 1, 2, 3, and 4.

The shaft C bears on one end a fly or balance wheel A which serves as a belt-wheel for transmitting motion to various kinds of machinery, and this enlarged portion of said shafthas alongitudinalkey-seat a in it,which receives a stud a that connects this portion of the shaft with a casting or spider E, the object of which is to aid in supporting the piston cylinder or ring E, which latter, together with a circular inside head F, is rigidly 7o bolted to the spider E, as clearly shown in Figs. 4 and 14, and said head F is radially grooved at b b to afford guides for two sliding pistons G G, hereinafter described. On the inner side of the recessed portion of the head F is secured an annularly and peripherally packed ring F. At the opposite open end of the cylinder A, inside thereof, is the open ringhead B and also a packing-ring F which latter is inside of the ring-head B and is So slotted at Z) to afford guides for the back ends of the two buckets G G. The ring-head B is open, and it is cast with a bracket B, which extends inside of the cylinder 1, and is constructed with a journal-box C for the sleeve C which latter is rigidly secured to the journal-box C by a set-screw a (Shown in Fig. 4:.) Inside of the sleeve C the reduced portion C of the main shaft C rotates, and to the inner end of an enlargementof 0 the said sleeve a cam-disk H is rigidly secured, so that while the inner cylinder E, with its head F and rings F W, is free to rotate with the main shaft, the said cam-disk H is stationary.

The cam-groove c in the face of the disk H is ellipsoidal, as shown in Fig. 13, the upper portion being eccentric to the axis of the disk and the lower portion concentric thereto, the object being to give the proper radial reoip- IOO roeation to the pistons G during their revolution, so that during the operation of the engine live steam will act on one side of these pistons and exhaust-steam escape from the opposite side, as will behereinafter explained. Both pistons are alike in form and construction. Each rectangular body (Z has a groove in its outer edge and in its ends adapted to receive a waved spring (1', (shown in Fig. 17,) and this spring is covered by an angular packing (1 which is preferably of hardened steel and constructed with hooked retainingends (1, adapted to engage with the body of the bucket at its inner corners, as shown in Fig. 1.7. The packing (I) is springy, so that by the expansion of the waved springs (Z the outer surface of this packing will accommodate itself to and be held steam-tight against the inner surface of the cylinder A and the radial guiding-grooves for the ends of the pistons.

On the portion 0' of the main shaft a cylindrical boss or collar is rigidly secured, havin g radial stemsff suitably secured into its periphery diametrically opposite each other, as shown in Fig. 2. On these pins or guides ff slide radially sleeves or tubes ff", which are suitably secured at their outer ends to the inner edges of the two buckets G G at the middle of their length. The sleeves f f have toes or studs f which protrude into and engage these sleeves with the cam-groove c in the face of the stationary disk II, above de scribed. The sleeves f f pass freely, but

' steanrtight, through the wall of the cylinder E, so that when this cylinder is rotated either to the right or left the radial moven'lents of the pistons will coincide with the shape of the said cam-groove and will impinge against the inner side of the cylinder E during their revolution.

At the upper end of the annular steamchamber surrounding the cylinder E, and in the median line of the main cylinder E, is a stationary block A", which subdivides said chamber into what may be termed a livesteam compartment and an -exhanst-steam compartment, and the buckets successively pass beneath this block they are fully retracted, as shown in Figs. 3 and l. The live steam therefore acts directlyandflxpansively on the buckets in their rotation.

The casting or valve-box I) above referred to is constructed with a cylindrical valveehamher J, which is subdivided by a vertical partition g, and with. one of these chambers the live-steam pipe I communicates, and with the other chamber the exhauststeam pipe I communicates, as clearly shown in Fig. 4.

Inside of the steam-box is applied an endwise-adjustable hollow valve V, which is ported at 71. It, and which is provided on one end with a hand-lever M, the upturned portion Nof which engages with a stem n on the exposed end of the valve V, so that by vibrating said lever about its fulcrum at m the valve V can be moved endwise, the said lever being held after adjustment by a rack 1'.

(Shown in Fig. 3.) The said ported. valve V is applied inside of a cylindrical receiver \V, which ported, as shown at '1' i 1' i 'i, Fig. 4, the ports communicating with the steamspace between the cylinders A E, as indicated by dotted lines in Fig. 2.

In operation, when the valve V is adjusted so that one port 7t registers with a port '6, steam will pass through port 71., through valve V its port h, and through port '11 into the steanrspace 411, and rotate the cylinder E and its shaft 0 in one direction, the exhauststeam escaping through the ported valve-box and its outlet-pipe I \V hen valve V is ad justed so that the ports i 71, register, the engine will be reversed.

It is obvious that the valve V may be adjusted to admit a full head of steam or any desired quantity of steam, according to the speed required or the work to be performed.

liaving described my invention, what I claim is 1. The combination, with the main cylinder, of the inner cylinder bearing radially-reciprocating pistons, the grooved head and grooved ring at the ends of the inner cylinder adapted for guiding the pistons, the spider E, connected to the head F and inner cylinder and to the main shaft, the fixed cam-grooved disk II, and the sleeves secured to the pistons and guided by stems, all as specified.

2. In a rotary engine, the combination, with the main cylinder, of the internal cylinder having an open end and a closed end, the cylinder E, provided with radially-grooved flanges and the pistons working therein, the spider E, securing this cylinder to the main shaft, the sleeves f, secured to the said pistons and guided by rods f, the stationary camgrooved disk ll, for actuating the said sleeves and pistons, and the bracket secured to the open head of the casing or main cylinder and affording a journal for one end of the main shaft inside of the open-end cylinder E, all as specified.

3. In a rotary engine, the combination of the external cylinder A, having one end. open, the internal open-end cylinder E, rigidly secured to the outer cylinder, as specified, and provided with radially-grooved flanges having movable pistons, the stationary disk ll, having a cam-groove in one face, the radiallymovable sleeves secured to the said pistons, the guide-rodsf, secured to a boss on the main shaft C, the spider E, securing the cylinder E to the head thereof and itself socured to the main shaft C, and the bracket 13*, affording a journal-box for a sleeve all as specified.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES R. DELLEIBAUCII.
