citizen y of the To all 'whom "it may conccm..

Be -it known that I, WILLIAM FARRELL, a United States, residing at Philadelphia, in thev county of Philadelphia and State of Pennsylvania, have invented an Electricl Engine; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make andV use Ythe saine.

My invention relates to electric motors, especially adapted for use in a power house to run dynamos. y In myiiivention the frame', armature and rheostat of `a motor are all mounted on one revolving--body so lthat 'the armature will travel around a stationary track when said body revolves. It is not my intention to interfere with the construction of the motor, but Inyidea is to mount theinotor itself upon a revoluble body by which the. revolutions of the armature of the motor areeX- changed on a stationary body for the revolutions of the frame of the motor secured to the revolving body The frame l, of the motor should of course be securely fastened to the revolving body. By placing the motorl in this position, it is givenO an enormous mechanical purchase and lis capable of ,30

making a full revolution around the center without a change or reversein movement as\ is required by the piston rod of anengine for example. The momentum of the revoluble body, which is made solid and heavy, is much greater than the band wheel of an engine. Furthermore, the use of my motor will diminish the load of friction by doing away withfcounter-shaft pulleys, belts and beltwtighteners.

My invention consists further in the features` of construction and combinations of devices hereinafter described and specified in the claims.

In the accompanying drawings, illustrating the preferred einbodimentof my invention: Figure 1 is aside elevation of a motor constructed in accordance with my invention. Fig. 2 is an enlarged plan view showing' the revoluble body in central section. Fig. 3 is an 'enlarged sectional view taken on the line :zc-w of Fig. 2 looking in the direction of the arrow and showing the con-` struction andarrangement Vof the trolley engaging the lcircular wires. Fig.' 4' is a broken detailed view showing the particular construction of the trolley and the arrangel nient of the two wheels contactingthereon fwith two-circular wires, and Fig. 5 is a plan view of a modiiiedconstruction, the revoluple body being shown in central section "as in Fig.' 1. y v

betweenwhich the revoluble body 3 is hung. Said revoluble body may be mounted to freely rotate upon a fixed shaft et as illustrated in Fig. 2 or it may beI keyed, as at 5,

shown in Fig. 5. When the 'shaft is revoluble, itfmay be'extended beyond its bear.- ings on the support-S and carry azdri've pulpown may be .taken from the revoluble body by Van auxiliary shaft 8'V carrying a pinion 9 engaging an internal gear 1.0 Xed tothe side of said revoluble-body as shown in`-Iv*`i,f i;,-`2. either'arrangei'nentthe ower of Vthe motor may be transmitteddirectly from the revoluble body, as for instance, by a belt 11- mounted'the'reon as illustrated in'Fig, 5, f

A stationary track or gear wheel 12 lis cast on or rigidly securedto one of the su ports and is Iarranged parallel tothe side face o f the revoluble body. y

An electric motor .13 of any ordinary or inthe revoluble bodyiwitli its frame or cas- .cured to ,said body. The armature of the motor carries a wheel or pinion 15 engaging or meshing with the stationary track or gear wheel 12. By this arrangement, it will be seen that when the armature of the motor revolves the pinion 15 will travel around the stationary gear wheel 12 and will cause the body 3 to rotate.

face of the stationary gear are arranged two These Wires are charged with electricity through the feed wires19 and 20 which, may be passed through the stationary gear and one of which carries a controlling switch' 21. A trolley 22 is pivotally mounted on the revoluble body and carries twn wheels 23 and 2&1 contacting respectively with the circular wires 17 and 18. Said wheels are kept pressed against these wires by means of a spring- 25v connected at its opposite ends to the revoluble body and trolley. The current collected by the wheels on the trolley from Referring more particularly to the draw-I suitable construction is mounted in a cavity' ing securely bolted as at 14 or otherwise se.

parallel circular wires 17 and 18 respectively.

ings, 1 and 2 designate stationary supports or otherwise iXed to a revoluble shaft 6, as

ley 7,' see Fig.- fwlien the shaft s'iXed,

Supported by brackets 16 on. the inner I 5 2. A device ofthe circular vwires is carried to the motor by means of the wires or connections 26.

From the foregoing description it will be seen that when the switch 21 is turned on the 5 current from'a source of supply will pass through the feed wires 19 and 20,.the circu-l 7lar wires 17 and18, the trolley and its wheels and the wires,26 to .the motor. The armarevolve and the gear carried thereby begin to travel around the stationary track or gear Wheel thereby causing the revolution of the body After said body has made a few revolutions it will develop a great mothe rotation of said revoluble body.

Where it is desired to .develop a greater .horse power than can be obtained from `the 20 use of a single motor, two or more motors may be mounted on the revoluble'body and connected with the stationary track and driven in a similar `manner as the single motor. In' Fig. 5 I have `illustrated two motors mounted on the revoluble body. In this `figure I have also shown two stationary tracks, one at each side of the revoluble body. The motors in this construction carry pinions on each of the ends of their armatures sov that the pinions at one side engage one-stationary track and those on the other side the other track..

' I am aware that other changes may be made inthe constructionsn shown and described in'this application without departing from theV spiritvor sacrificing the advantages of my invention. I, therefore, do not con- "nine myself to the exact constructions and `arrangements herein set forth. f

As illustrated in Fig. 1, a suitable automaticvrheostat 271, may be mounted on the revoluble body so that the three parts of the electric'motor are placed on said revoluble body and work together in the revolution thereof.

I claim:

1. The combination, with a revoluble body,
