ROTARY. STEAM-ENGINE.
SPECIFICATION forming part of Letters Patent No. 288,102, dated October-2, 1823. Application filed May 13, 1882. No model.)
T0 aZZ whom, it may concern.-
Be it known that I, AUGUSTUS B. 001), a citizen of the United States, and a resident of Fountain Hill, in the county of Ashley and State of Arkansas, have invented a new and valuable Improvement in Rotary Steam-Engines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.
Figure 1 of the drawings is a representation of a vertical cross-sectional view of my steamengine, and Fig. 2 is a side view of same with the one section removed.
This invention has relation to rotary steamengines; and it consists in the construction and novel arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claims appended.
In the accompanying drawings, the letter A designates the annular piston-chamber in the piston-cylinder B, which is made. in two sections, C 0, having flanges a, perforated at b for the passage of bolts 0, whereby the sections are secured together. Each section is provided with central enlargements, D, around the shaft 0, said enlargements being recessed and provided with pillow-blocks or brass bearings g, which are adjustable by means of setscrews h to take up the lost motion of the main shaft, which these hearings support. The main shaft carries the piston-plate or diskarm E and the eccentric D, whereby the slide valve F is operated. The disk-arm E is eircular, and turns in a narrow circular chamber, 9, around the main shaft, which communicates with the annular piston -chamber A. The marginof the disk-arm extends to the pistonchamber, and the piston-head G, which revolves around the annular chamber A, is secured to the edge of the disk E by means of an arm, h, of the disk, which extends through abearing in the head, and is secured by a nut. The pistonhead is provided with packing rings around its edge, and is made in wedge form, or wider at its outer than at its inner portion, in order that it may wear uniformly. Annular lateral recesses 71 are made in the walls of the narrow center chamber, 9, near ment K is of sufficient size to close the pistonchamber when seated across the same, and is provided with a stem, a, whereby it is con nected to a small piston, 12, which works in a small chamber, 1', in the projection H. In this proj eetion are formed, also, the steam-ports s and the exhaust-port 8, extending to the valve-seat.
L indicates the valve-chamber, which is secured to the section 0' of the cylinder, and F represents the slide -valve therein, which is connected to the eccentric D 011 the main shaft by means ofa connecting-rod, N. Small steamports 2 and z extend to the steamchamber r of the abutment-piston p, and serve to supply the steam for working the abutment. It may, however, be found advisable to work the abutment by means of a cam on the main shaft, having a connection extending to the stem of the abutment, and operating to move the abut ment quickly out of the piston-chamber just before the piston-head passes its seat, and then quickly back into position.
The movement of the engine is simple. The abutment being in position across the pistonchamber, steam entering by one of the steamports forces the piston-head to revolve. The steam has full power all the way around the piston-chamber, except for about one-eighth of its length, this space being taken up in the working of the abutment; or the steam may be cut off at three-quarter stroke and the expansion depended on for one-eighth. When the abutment is moved out of the pilston-chamher by its cam or by the pressure of steam under its piston, the main piston-head passes its seat, and the abutment is then quickly returned to its position acrossthe piston-chamber.
A reciprocating abutment operated by steam tions and forming small openings between the V faces of the teeth, through which the steam enters. p
Having described this invention,what I claim, and desireto secure by Letters Patent,
1. I11 a rotary engine, the annular pistonchamber A, and the abutment-slideway m and central narrow circular chamber g, communieating therewith, and having the lateral 'recesses k, packing-rings l, and set-screws, the main shaft 6, disk-arm E, piston-head G, and abutment-slide K, substantially as specified.
I p a p 296,102
2. In a rotary engine, the combination, with the piston-chamber and the piston-head revolving therein, of the transverse slideway m and the abutment-slide K, the center chamber, 9, its packing-rings l, and the disk-arm E, and the steam-ports s, leading from the pistonchamber to the valve seat, substantially as specified.
3. In a rotary engine, the disk-arm E on the main shaft 6 and the wedge-form piston-head G, secured'to the edge of said disk-armby the arm h and nut, substantially as specified.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
' AUGUSTUS BALDlVIN XVOOD.
