ANDREW PHILLIPS, OF CONEMAUGH, PENNSYLVANIA.

REVERSIBLE ROTARY STEAM-ENGINE.

Specification of Letters Patent.

Application filed December 8, 1914. Serial No. 876,121.

To all whom it may concern:

Be it known that 1, ANDREW PHILLIPS, a British subject, residing at Conemaugh, 1n the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Reversible Rotary Steam-Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en-' able others skilled in the art to which it appertains to make and use the same.

This invention relates to steam engines, and more particularly to an engine of the reversible, rotary type.

The invention has for its object to provide a rotary motor having a novel arrangement of steam feed pipes and a valve controlllng the flow of steam through the pipes, whereby the direction of rotation of the rotor may be quickly and easily reversed.

Another object is the provision of a rotary steam engine embodying a'novel type of rotor having twin sets or series of blades separated by a partltion or wall to lncrease the power efliciency of the engine.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawings, in which,

Figure 1 represents a side elevation of the engine complete, partly broken away, and Fig. 2 represents a sectional view on the line 22 of Fig. 1.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates the base of the engine which is supported upon a suitable foundation 6 and on which is secured a cylinder 6 provided with removable side walls 7 secured thereto by the bolts 8. The side walls 7 of the cylinder are formed with axial openings 9 alining with the bearings 10 secured on standards 11 positioned upon the base 5, and rotatably receiving the shaft 12. A rotor is keyed on the shaft 12 between the side walls 7 and includes a body or hub 13, a partition 14 secured circumferentially thereon and arranged centrally between a plurality of blades 15 arranged in series on opposite sides of the partition 14. The base or inner portions 16 of the blades are concave and secured to the hub portion 13, and the outer extremities of the blades are formed with concavo-convex heads 17, the concave faces being arranged inwardly.

Nozzles 18 are secured in one side of the cylinder 6 and at an angle to a radial plane of the rotor to direct a spray of steam against the blades 15 to rotate the engine in one direction. The nozzles 18 are connected by a U-shaped pipe 19, which latter communicates with a branch pipe 20 secured in one of the outlet ports of a three-way valve 21. A pair of nozzles 22 are secured in the wall of the cylinder 6 at a point approximately diametrically opposite the nozzles 18 and are disposed at. an angle to a radial plane of the rotor to direct a spray of steam against the blades 15 to rotate the engine in an opposite direction. The nozzles 22 are connected by a U-shaped feed pipe 23, which latter communicates with a branch pipe 2 1 secured to the web portion thereof, and communicating with another outlet port of the valve 21. A steam feed pipe 25 is connected with the valve 21, and the latter is adapted to be 0 erated by a hand lever 26 carrying a pawl 2 adapted to engage the rack segment 28 to Patented one 8, 1915;

lock the lever 26 in adjusted position. By

proper adjustment of the valve 21 the flow of steam to the pipes 19 and 23 may beentirely stopped or steam may be admitted al- .ternately to said pipes to rotate the engine in the desired direction, as will be understood.

The lower portion of the cylinder 6 is formed with an opening communicating with an opening in the base 5 and constituting an exhaust port whereby steam is exhausted from the interior of the cylinder.

hat I claim is 1. A rotary reversible steam engine comprising a casing or cylinder, a shaft rotatably mounted in said cylinder, a rotor secured on said shaft within said cylinder including two sets of radially disposed blades, a partition separating the sets of blades, concavoconvex heads carried by the outer extremities of the blades, pairs of substantially diametrically opposed nozzles secured to the wall of said cylinder and disposed at an angle to a radial plane of said rotor, steam feed pipes connected with said pairs of nozzles, and means for alternately admitting steam to said feed pipes.

2. A rotary reversible steam engine comprising a casing or cylinder, a shaft rotatably mounted in said cylinder, a rotor secured on said shaft within said cylinder including two sets of radially disposed blades, a partition separating the sets of blades, concavoarranged in the second mentioned pipe, and convex heads carried by the outer eXtremia steam feed pipe communicating With said ties of said blades, pairs of substantially diathree-Way valve.
