normar ENGINE.

Specification of Letters Patent. Application filed February 27, 1909.

To all whom t 'may concern.'

Be it known that we, (1) Fnnnnron WUN- DEnLron vand (2) Louis Kenianen, citizens of the United States of America, residing at (1) Swissvale, county of Allegheny and State4 ol Pennsyh Vania, have invented certain new and useful mprovements in Rotary Engines, of which the following is a specification, reference being. had therein to the accompanying draw* ing.

This invention relates to rotary engines and the invention has for its object to pr0 vide a novel engine from which a high degree of efficiency can be obtained with a minimum eX enditure of entirety eing economically operated to dcvelep power.

Another object of the invention is to provide a .reversible rotary engine having a novel governor mechanism for controlling the speedoi" the engine..

A 'urther ol'ijei-.t ol the invention is to provide a steam turbine wherein the propeller Wheels are arranged to develop a high degree of power which through the medium of a train o1' gears is transmitted to a single power shaft.

` ment 5 is W ith the above and other objects in view which will more readily appear as the invention is better understood, the same consists in the novel construction, combination and arrangement ol parts to lie-presently described. and then'elaimed.

.ln the dra-wings, `Figure 1. is a vertical transverse seetional view of the engine, illustrating the valve thereof in position for driving the engine'in one direction, Fig. 2 is a vertical longitudinal sectional view of the engine, vFig. 3 is a vertical transverse sectional view oi," the engine illustrating the valve in position to drive the engin e? in an op posite direction, from that shown in Fig. 1, and llig. 4 is a similar view of the engine with the gear casing removed.

ln the drawings, 1 designates a base plate supporting a cylindrical casing 2, said casing having a detachable plate 3, and exhaust ports L atA the top and bottoni of said casing. 'lhe easing 2 is provided upon the rear side thereof with an extension (j, provided with a steam inlet port 7 adapted to connect with a suitable steam supply pipe S., The central enlargee fuel, the engine in itsv a centralenlargement 5 havingv (2) East Pittsburg, in the raten-ted muy is, 19,09. serial No. 480,446.

a valve plug 10,said block extending into the casing 2, and into a seat 11 provided therefor upon the inner side of the plate 3. The plug 1() is retained within the seat 9 by a stuffing box 12, and said plug is formed with two longitudinal cylindrical compartments 13 and 14, said compartments being se arated by a partition 15 provided with a va` ve seat establishing communication between said compartments. The outer end of the'eompartment 13 is closed, by a detachable cap 16 provided with a transverse opening 17 intersecting a portion of the valve plug l0, whereby a suitable instrument or wrench can be used for rotating the valve plug 10.

ln the easing 2 is secured a valve frame -comprising a central body 18, and radially provided lwith a tapering seat'Q for l governor mechanism disposed arms 19.` The body 1S of the frame surrounds the valve plug 10, and is provided with two sets ol tangentially disposed ports 20 and 2] Ythese ports being designed to communicate with two sets of radially disposed ports 22 and 23 formed in the valve plug 1U, and communicating with the compartment 14. The edges of the arms 19 of the valve traine are curved, as at 24, to provide eylinders for four sets of propeller wheels, each set comprising two wheels 25 and 26A mounted upon a shaft 27 journaled in the easing 2 and the detachable end plate 3, said shafts protruding through said end plate. The propeller wheels and 26 have lthe periphery thereof provided with tangentially disposed pockets 28 adapted to register with the ports 20 and 21.

The outer side ol the end plate 3 vided with acentral bearing ity of antifriction rollersl 3() supporting a large gear wheel 31 adapted to mesh with small gear wheels 32 mounted upon the outer ends of the shafts 27. The large gear Wheel 31 is provided with a tubular hub 33, closed by a detaehableslot 34 carried by a shalt 35, journaled in a bearing 36 carried by the base plate' l. The gear wheels 31. and 82 are i nclosed by a casing 37 secured to the end plate. 3, and by a collar 88 carried by the hub 33. Theeasing 37 is provided -with a stulling box 3S) through which one ofthe shafts 37 extends and is adapted to be j rovided with .a pulley i pro- ',wheel (not shown) w ereby machinery can be driven by the enefine.

y the tubular hub 33 the is used for .controlling In connection Wit 29 for a plurali nected to a valve rod 45 extending through the bearing 29, end plate 3, compartment 14 of the valve plug 10 into the compartment 13 of said plug, where a stem is provided with 15 and shut olli' a supply of steam to the compartinent 14, the steam being admitted to the compartment 13 through a plurality of radially disposed ports 47 formed in the valve plug 10 and communiczi-ting Wi th the port 7, through the medium of an annular groove 4S formed in the periphery oi the valve plug 10.

ln operation, the steam admitted to the fompartment 13 is adapted to pass through the valve seat 15 into the compartment 14, and through the ports 22 or 23 communicating with the ports 2O or 21, As shown in Figs. 1 and 2, the ports 22 communicate with the ports 20, consequently the four wheels 25 will be driven by steam entering the pockets 28 of said wheels. With the lour wheels 25 revolving in the 'same direction, the' large gear wheel 31 will be driven and power can bc taken from said wheel, either through the medium. of the prolonged shaft 27 or the shaft 35, the former being preferable.

Should either of the shafts revolve with too great a rapidity, the bell-crank arms 4() are swung outwardly by centrifugal force and through the medium of the cross head 42 shift the valve rod 45, and close the valve 46 until the speed of the engine is reduced.

To reverse the engine, the valve plug 10 is rotated, until the ports 23 register with the ports 21, and then steam is admitted tb the pockets 28 of the wheels 26, and the proonged shaft 27 and the shaft 35 are driven in an opposite direction.

It will be observed from the foregoing description that the various parts of the engine are compactly assembled, and that the operation of the engine is easily controlled by a single attendant.

It is thought that the operation and utility will be fully understood without further description, and While in the drawings there is illustrated the preferred embodiments of the invention, we do not care to limit ourselves to the exact manner of assemblage without departing from the spirit or scope of the invention. l
