ROTARY STEAM-ENGINE.

Application filed March 13, 1916.

To all whom it may concern Be it known that I, VAN EVERY EDWARDS, a citizen of the United States, a. resident of Decatur, in the county of Macon and State of Illinois, have invented new and useful Improvements in Rotary'Steam-Engines, of which the following is a specification.

My invention relates to improvements in steam engines and the principal object lsto provide a mechanism of that character which will develop high power and efficiency with a minimum consumption of steam. j a I To the accomplishment of the foregoing and such other objects as may hereinafter appear, my invention consists in the combination, construction and arrangement of parts hereinafter described and then sought to be defined in the appended claims, reference being had to the ings forming a. part hereof, and which show merely for the purpose of illustrative disclosure, a preferred embodiment'of my in vention, it being understood that various changes may be made in practice within the scope of the claims without digressing from my inventive idea.

In the drawings: Figure 1 representsan elevation of a plurality of engines constructed according to my invention, one of. the motors being shown in section; Fig. 2 is aside elevation plate being removed, and parts being shown in section to facilitate disclosure.

Referring now to the drawings, the numeral l designates suitable supporting memsecured to a concrete foundation or in any other suitable manner. On these supporting members are mounted. the casings of theengine and also the supports for the shaft. This shaft is designated by the reference character 2 having the bearings 3 on supports 1 and is preferably provided at an intermediate point with the clutch mechanism 5, whereby the two parts of the shaft may be coupled or disconnected as desired.

6 and 7 designate suitable fly wheels, 8 a governor driven by means of .thebelt and pulley arrangement 9.

10 indicates a steam header having the supply pipes 11 leading into the separate engines.

Each engine or motor includes the casing 12 which is bolted to the supports and which Specificationof Letters Patent.

has the cylindrical compartment 13 therein. In this compartment revolves the rotor 14- which is keyed or otherwise secured to the shaft 2, the shaft 2 running loosely within the casing 12. The casing 12 is provided with the side cover plate15 secured thereto by means of bolts 16, as shown. packing members 15 are provided between the wall of the casing and sides of the rotor so as to provent the escape of steam.

Referring now particularly to Fi 2, the numeral 17 designates the inlet connection and 18 theexhaust connection. On the in side face of the casing I provide a plurality of dove-tailed recesses 19, one of which is arranged between the inlet and exhaust connections. lVIounted in these dove-tailed recesses are the holding and guiding members 20 which have the dove-tailed portion 21 to fit the dove-tailed recess and also having the laterally extending wind portions 22 which rest against the inside of the casing. Adjustably mounted in each holding and guiding member 20 the pressure block 28, being located in the recess 24 in the holding and guiding member and adjustable by means of the screw member 25 having the squared head 26. This screw member has the loose connection 27 with the pressure block soas to permitits rotation therein.

The rotor is provided on its peripheral face with the plurality of buckets or recesses 28 which are formed as shown, having the abrupt edge 29 and the inclined face 30 leading to a feather edge. These buckets or recesses are arranged close together about the face of the rotor. V

The steam is lubricated before entering the engine so that all the bearings are thereby lubricated.

As shown in Fig. 1, I can use both high and low speed engines which may be coupled to work together or separately, according to working conditions. The governor controls or regulates the admission of steam. The

rotor will flow in oil, thereby lubricating the packing rings about the sides thereof.

he operation of this mechanism is as follows: The pressure blocks with the exception of the one between the inlet and exhaust Suitable orrron.

to restrict the circuit of the steam so that more and more of its force is exerted against the buckets 28 and particularly against the abrupt face or wall 29 thereof, thereby gradually increasing the speed of rotation of the rotor. ing under the pressure blocks and expands on passing each pressure block. The buckets are arranged so that when one is under a pressure block, the supply of steam thereto being cut OK, the next one will be subjected to the steam from the inlet connection. This is true in connection with all of the pressure blocks so that a maximum efficiency in operation is obtained.

W hat I claim is:

1. In combination in a rotary engine, a cylindrical casing, a rotor mounted therein, packing between the sides of the rotor and the casing, said casing having inlet and exhaust connections, a plurality of pressure blocks adjustably mounted in said casing and adapted to be moved toward and from the rotor, one being located between the inlet and. exhaust connection, said rotor having a plurality of buckets or sockets provided in the face thereof.

2. In combination in a rotary engine, a cylindrical casing immovably mounted, a rotor mounted therein, packing between the sides of the rotor and easing, saidrotorbcing provided with a plurality of recesses or buckets on its face, said casing having inlet and exhaust connections, a plurality of pressure blocks located at intervals about the casing, one being located between the inlet and exhaust connections.

3. In combination in a rotary engine, a cylindrical casing immovably mounted, a rotor mounted therein, packing between the sides of the rotor and easing, said rotor being provided with a plurality of recesses or buckets on its face, said casing having inlet and exhaust connections, a plurality of pressure blocks located at intervals about the casing, one being located between the inlet and exhaust connections, and means for adjusting the pressure blocks to and from the rotor.

Copies of this patent may be obtained for five cents each, by addressing the being provided with The steam is confined in pass-V cylindrical casing immovably mounted, a rotor mounted therein, packing between the sides of the rotor and casing, said rotor a plurality of recesses or buckets on its face, said casing having inlet and exhaust connections, said casing having a plurality of guideways, a guiding and holding member mounted in each guideway and a pressure block adjustably supported by each guiding and holding member.

5. In combination in a rotary engine, a cylindrical casing immovably mounted, a rotor mounted therein, packing between the sides of the rotor and easing, said rotor being provided with a plurality of recesses or buckets on its face, said casing having inlet and exhaust connections, said casing having a plurality of dove-tailedguide-ways on the inner face thereof, a guiding and holding member having a dove-tailed portion mounted in each guide-way and said guiding and holding member having asocket in its face, a pressure block slidably mounted in each socket and means extending through the guiding and holding member in casing IEOr moving the pressure block in and out to vary the distance thereof from the face of the rotor.

6. In combination in a rotary engine, a

cylindrical casing immovably mounted, a rotor mounted therein, packing between the sides of the rotor and easing, said rotor being provided with a plurality of recesses or buckets on its face, said casing having inlet and exhaust connections, said casing having a plurality of dove-tailed guide-ways on the inner face thereof, a guiding and holding member having a dove-tailed portion mounted in each guide-way and also having wing portions bearing on the inner face of the casing and said guiding and holding member having a socket in its face, a pressure block slidably mounted in each socket and means extending through the guiding and holding member in casing for moving the pressure block in and out to vary the distance thereof from the face of the rotor.
