To all whom it may concern.-

Be it known that I,- ALEXANDERMGCAHON,

. a citizen of the United States, residing at St.

I each revolution of the hub as the sparking-.

Joseph, in the county-of Buchanan and State of Missouri, have invented certain new and useful Improvements in Air and Vapor Rotary Explosive-Engines; and I do declare the following to bee. full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertaihs to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. I

The object of my device is to provide an; air and gasolene rotary explosive-engiue in which by means of pockets, plungers, and provision for striking electric. sparks and a} feed-pipe and ports located within the-hub the engine supplies its pressure 'tankwithg fresh air, mixes it with gasolene,"-drivesthe: '1'

mixed air into a chamber of the engine," at which chamber three explosions occur during points in each hub-pocket separate and cause an electric spark, thus securing great power from a given amount of, fuel and constituting an engine with a hub that is aself-fee'der.

In the drawings, Figure l is a view of a fresh-air pressure-tank, a gasolene-t-ank, the mixing-bulb, and their connections and an end view of the stationary axle, revoluble hub, the chambers, pockets, plungers and plunger-slides, and the electric sparkers, the end plate of the engine being removed to permit an interior view. Fig. ,2 is a vertical cross-section of the engine and its pressure and gasolene tanks, the mixing-bulb, and connections in elevation, the feed and air orslot way outside connections, the paddle-fan and its gear, and the drive-wheel for starting the engine. Fig. 3 is a detail end view of the stationary axle, the air and feed passages or slotways in the; axle, and the ports in the hub,

leading to the axle. Fig. is a detail of portions of the engine end plates, the hub and hub-rim, the electric plate out-side the engine, the sparker-pin .in a pocketof the hub, the connection between said sparkerpin and plate, the wire attached to the plate, and the.

wire screwed to the engine. Fig. 5 is a detail of a section of the hub, a plunger and its slide,

J is arpipe having a throttle-valve J and extending from fresh-air pressure-tank D to' chamber E to supply air for starting the mechanism.

K isan air-slotway in stationary axle B, extending along the periphery of the axle. This slotway is provided at one end with a pipe K, which passes up outside the engine and connects with the bnlb-baseohtlet I), through which it receives mixed'air and gasplen'e from bulb I and transmits and "feeds'it through slot K and into the pockets L I: through ports f f as the port of each pocket is revolved over said slotway. Pockets-LL are also provided with ports e e, and as each of these ports is revolved past the mouth of bulb-base outlet b said outlet also feeds said pockets through said ports with air and gasoone.

.where the 5 guideway, the plunger as it passesdraws its 'sparker down until .its point drags on and oil sparker-point P, causing an electric spark'as they separate,' .which ignites the mixed air and gasolzene in that pocket, resulting in an 0 explosion that drives the plungers forward.

, Q is an airway in the periphery of stationary axle B upon the side opposite feed-slotway K, and Q is an air-pipe forming'connection with an end of said airway.

R is a paddle-fan run by rubber frictiongear R, connected with an end of hub O for the purpose of blowing fresh air into pipe Q and airway Q and keeping pure air in pockets L L and also fresh 5o culation being secured through escape-ports S S. To prevent fresh air from chamber D or vapor from chamber guideways m m in the end plates, a pin V, with coil-spring V, is set at each end of each 5 of the guideways. As each plunger passes through the guideways it pushes thesepins power of the coil-spring. drives its pin back, thus closing the guideways against the pits- 6o sage. of air or vapor. Y

The tanks being provided with their supply of fresh air and gasolene, in order to start the engine it is only necessary to open throttlevalves 2 and h, thus permitting fresh air and gasolene to pass freely into mixing-bulb I, whence, having become mixed, the process offlowing or seeping through the channels alair in chamber D, cir-,

E passing throughready described into, the pockets begins. Valve J in pipe J is then opened, permitting fresh airto be forced from pressure-tank D into that portion of chamber E that is above that-plunger which at the time is in the upper half .of said chamber. This pressure of air forces said plunger-downward, thereby putting in motion all the revoluble mechanism;- Owing to the incline of guideway m in this upper portion of said chamber, as the plunger is pushed farther down it passes farther out of its slide'F until its sparker-point P touches sparker-point P in the pocket, and

as the hub revolves its plunger sparker' point drags on and 01f the pocket sparker-point,

causing an electric spark "as they separate. The air'and gasolene in that pocket is instantly ignited by the-sparkand'an explosion at once occurs. Throttle-valve J in pipe J may then be turned off, stopping a further flow through it of fresh air from the pressuretank. In the meantime ascending plunger F in the upper part of opposite fresh-air chamber D is driving fresh air up through pipe d into pressure-tank'D'. After the explosion just described occurs the plunger moves on down to air-escape ports S S,through which the burned v'apor passes out of the em gine. As the hub is revolved paddle-fan R constantly blows fresh air through air-pipe Q into airway Q in stationary axle B and thence through hub-ports ff into the hubpockets. The air passes thence out of the pockets through outer ports e e into chamber E and thence out through said escape-ports, leaving'nothing behind but fresh air. Every time a plunger gets past said escape-ports the escape-ports and fresh-air-fe'ed ports are all cut off. The plunger as it ascends chamber D presses the air that isabove it in said chamber up into pressure-tank D through pipe (1. It will beseen that as a plunger is moving down the incline in chamber E there is a decreased leverage on the plunger that is passing up'chamber D, compressing the fresh air in said chamber and pushing it up into the pressure-tank, and economy of power is thereby secured.

While I have not shown or described a water-jacket, it is quite evident that one may beused with my device and that changes may be made in the forms and arrangements described "herein' without departing from the scope of the inventionl What I claim, and desiretose'cureby Let- I tore Patent, is away; but the instant the plunger passes'the' 1.
