ROTARY ENGINE.

No. 882,591. Specification of Application filed October 4,

T 0 all whom it may concern:

Be 1t known that 1, WILLIAM Mosns SPEN- at Burns, in the county of Dickson and State of Tennessee, have invented certain new. and useful Improvements in Rotary Engines, of which the following is a specification.

My invention relates to a rotary engine, and the object is to overcome the loss of motion or leverage on the machinery, and by my invention 1 am enabled by the two wheels to prevent any dead center, for as one wheel reaches a certain point and having given the full power of its stroke by the steam or leverage on its machinery from start to exhaust, and as the exhaust of the steam which retates this wheel escapes the other wheel is receiving the full pressure of the steam and prevents any lost motion or dead center.

The invention relates to certain other novel features of construction and combinations of parts which will be hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View in front elevation; Fig. 2 is a sectional view; Fig. 3 is a view of one of the wheels, and Fig. 4 is a transverse sectional view.

A represents the frame, and 1 is the shaft mounted on the frame and having fly wheels B, B journaled thereon at each end.

A casing C is supported on the frame, and it is preferably cylindrical in form and has a central web 2 therein, the web preferably being hollow in the center. Received within the casing are wheels D, D rigidly mounted on the shaft 1 and having their hubs extending through or into the openings formed by the web. The rims of the wheels are provided with

buckets

3, 3 having inclined surfaces and at the tops of the buckets wings 4i, 4 are inserted, which are spring-actuated to tend to cause them to extend. outwardly and bear against the surface of the casing. The other side of the bucket is more abrupt but has a sloping surface whereby the gate valves can readily and easily strike the surface of the wheel. The sides of the wheel are provided with recesses 5, 5 on each side having

packing rings

6, 6 therein, which are held outwardly by means of small coil springs, and these rings bear against the side of the web, and ends 7, 7 of the cylinder, which prevents any leakage of the steam.

The

ends

7, 7 of the cylinder are secured to Letters Patent. Patented March 24, 1908.

the casing and into the flanged edges of the ends.

Mounted upon the casing C is a steam chest 9, having

valves

10, 10 therein,.which are connected by levers 11 and 12 to the rocker arms 13 of the shaft 14-. Mounted upon the shaft to similar rocker arms 15 are eccentric levers 16, which are connected to the

eccentrics

17, 17 on the shaft 1., whereby the valves are operated as the shaft is revolved and the eccentric for the different valves is caused to reciprocate it in the chest to close the port or ports 18 therein. These eccentrics are so mounted on the shaft to COIIOSPODd to the wheels that the valvebegins to close or closes the port 18 before the buckets 3 on the wheel reach the exhaust port 19 in the casing.

Gate valves

20, 20 are mounted on the easing just ahead of the steam chest and are received in a suitable casing 21, and are springcontrolled therein by means of coil springs 22. These gate valves extend through the casing and bear against wheels D, D, and as the wheels are rotated after passing the exhaust port 19, and the port 18 in the steam chest is closed, by one of the valves therein, it strikes a bucket 3 on the wheel, causing it to move upwardly, and as the bucket passes from beneath it, it strikes the sloping surface of the bucket and again becomes seated on the surface of the wheel, and the valve 10 is drawn from the port 18 and the steam is permitted to strike the bucket and force the wheel onward; these gate valves preventing the steam from passing in but one direction through the cylinder, and always causing the wheel to move.

The operation is as follows:Stcam is admitted from the boiler (not shown) to the cylinder, causing the wheel or wheels to revolve, and they are so timed that the bucket 3 on one is at the top or near the gate valve when the other is making its revolution and is about midway thereof. The pressure of steam against the wheels causes the shaft 1 to revolve, transmitting motion to the fly wheel and to the eccentrics, which eccentrics are connected to the eccentric levers 16, which are connected to the rocker arms 15 tion to the rocker arms 14, which in turn are connected to the lovers 11 and 12, to which the valves 10 are connected. The eccentrics do not run together, but permit one lever to transmit motion to the shaft 14 to cause one the casing by means of bolts 8, S passing over on the shaft 14, thereby transmitting mo' of the valves 10 to operate and cover the port 18 as the bucket 3 on the wheel D passes the exhaust port E, thereby closing the steam supply to this Wheel, and as the wheel passes around it strikes one of the gate valves 20, causing it to rise upwardly, and as the bucket passes from beneath it the valve again becomes seated on the rim of the wheel and after it passes the gate valve, and has traveled a short distance, the valve is drawn from the port allowing the steam to strike against the back of the bucket, forcing the wheel around as the'other valve is closing the other port by the other wheel which is now reaching the exhaust valve E. At the same time the steam is entering the port and forcing the first-named wheel around, thereby preventing the loss of motion or stroke and the strain naturally due to the jerking motion, as an even stroke is always given to the machinery.

It is evident that many slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact construction herein set forth, but

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a rotary engine, the combination with a frame, a casing mounted on the frame, of a shaft, wheels within the casing mounted on the shaft, buckets on the wheels, pivoted steam to the wheels, means for actuating the valves alternately, and gate valves for preventing the fiow of steam in more than one direction through the casing.

3. In a rotary engine, the combination with a frame, a casing mounted on the frame, of a shaft, wheels within a casing mounted on the shaft, buckets on the wheels, pivoted wings in the buckets, a steam chest mounted on the casing having ports therein for the admission of steam to the casing, valves in the chest for regulating the flow of steam to the wheels, means connected to the shaft for operating the valves, and gate valves for preventing the flow of steam in but one direction.

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

WILLIAM MOSES SPENCER.
