To all fr0/wm may conce-rn.'
' Be it-known that I, EDWARD B. GaLLAHnR, a citizen of theUmted States, residing at Pontiac, in the county of Oakland and State ot Michigan, have invented certain ney rand' `u'seiul Improvements in Turbines, of which the following is a specilication, reference be ing had therein to the accompanying drawings.
This invention relates to a power generator, and the generator may take the torni oi' a turbine wherein steam, gas-or some motive fluid may be utilized for driving'the rotor of the engine, particularly the eXpansive torce of suoli tluid relative to abut ments disposed about the Jbody of the engine and the rotor thereot, the abutments being arranged so thatrthe expansive torce of the 4motive fluid may be completely expended in the engine, before such luid eventuallyrexhausts from the engine.
My invention aims to provide a `power generator that may be use/d for generalppurposes and be more elticient than internal combustion or othery types of engines. By being more efiicient a maximum amount of power may be obtained with a minimum eX- penditure of fuel, either in the from of `an y expansive fluid or a liquid under pressure.
My invention further aims to provide a power generator including a cylinder and a rotor that may be maintained liquid and fiuid tight and the arrangement of the rotor is such that easy access may be had to either.
My invention further aims'to provide a power generator which obviates the 'necessity ot using valves, springs or other movable parts, and the construction entering into the invention willbe hereinafter described and then claimed.
Reference will now be had to the' draw ings, wherein* Y l Figure l is a vvert-ical longitudinal sectional view of thepower generator taken on the line I-I ot Fig. 4;
Fig. 2 is a horizontal sectional view taken on the line II-II of 5, showing an intake port of the power generator;
Fig. 3 is a horizontal sectional view taken p on the line HIHI of Fig. 5;

viewota portion of the same taken on they line AV--V of Fig. 4; i
F ig. 6 is a cross "sectional view taken on the line VI-VI of Fig. 5, and
Figi 7 shows diagrammatic views` ot sets ot' passages inthe rotor of the power ,generator;
ln the'drawings, therei'erence numeral l" tained ior various purposes. y
The reference numeral 8 denotes `a `rotor having a hub'portion 9 mounted on the shatt 7, between the cylinder heads 3, and the periphery ot the rotor S perfect-ly fits inthe cylinder so that the same may freely revolve therein with a minimum spaceexisting be'l tween the 'periphery of the rotor and the Suitable pack` ing rings'or members 10 may be interposed between the cylinder heads 3 and theends of the rotor, and between the periphery oit the rotor and the inner annular wall o'lfthe cylinder. i The cylinder l is lrn'ovided with circum; tere'ntialiy arranged transverse chambers ll having 'tange'ntially ldisposed passages l2 communicating therewith, the f passages 'bef ing open 'at the innerrwall o'jthe cylinder and preferably tour in number tor each chamber. In the 'cylinder lare opposedl radially disposed intake ports 13 ander;-k haust ports Mathe intake ports being opposed relative to each other, also the e.\*hausty ports 14, so that the rotor 8 may be balanced in the cylinder. Theexhaust ports are twoin number at each side ot the cylinder, as shownin Fig. 3, `for the reason that the rotor is provided with two circumterentially disposed sets et pockets, there beingftwo exhaust ports for cach set. The sets ot' pockets, however, are served by a single intake port at eachk side of the cylinder and one of these intake ports is best shown, in Fig. 2.
Considering the rotor 8, it has its periph-rv y `oit the short pockets are in a common plane ot' rotation of the rotor 8 and the long pockets 16 are in a similar common plan-e at the inner side of the plane ot" the short pockets 15. The short and long pockets are open at the periphery ofthe rotor and the inner ends of the short pockets 15 communicate with the innei ends of the long pockets 16 by angularly disposed passages 1T, the passages beingdisl'wsed at angles' to the axis of the rotor as brought out by dotted lines in Figs. 2, 3, -1 and 6. t therefore possible to place the open ends of the longI pockets 16 in the same transverse plane as the short pockets 15 ot adjacent pockets. In other words. the'pockets of the rotor have overlapping portions and this permits a short pocket eoi'nmnnieating with an intake port allowing the motive fluid to pass through the long pocket and into a passage 12 of the chamber 11. The injection of motive fluid into the shortpockets 15 causes the motive fluid to impinge against the walls of the short pockets, the passages 17 and the walls of the passages 12 and the chambers 11, thereby causing the rotor to turn in a clockwise direction, and as each short pocket is brought'into registration with an intake port the rotor receives additional impulses.
Assuming that an expansive fluid, as steam, is vemployed for driving the rotor, the expansion of the steam in the pockets, passages and chambers will drive the rotor in a clockwise direction and if the expansive force of the steam .is not fully expended in the first cylinder chamber which it enters, the unexpended force will be utilized in the nent chamber entered by the steam.
l From the foregoing it will be observed that the short pockets o1 the rotor successively receive motive duid and consequently will keep Vthe rotor in motion. rlhe motive fluid not onlyA utilizes the short and long pockets of the rotor as abutments, but also the chambers ot the cylinder, and the arrangement o'f the pockets by which the intake ports will at times communicate with chambers ot the cylinder is very effect-ive especially in connection with an expansible fluid` as abutments are at all times coming into active relation for such fluid to impinge thereagainst.
It is thought that the operation and utility of the power generator will be apparent vithout further description, and while in the drawings there is illustrateda preferred embodiment o1 my invention, it is to be undei-stood that the structural elements are susceptible to such changes, in size, shape and manner ot' assemblage, as fall within the scope of the appended claims.
What I claim is 1. A power generator comprising a cylinder having opposed intake ports and opposed 'exhaust ports? said cylinder having transverse chambers therein coi'ni'nunicating with said intake ports, said cylinder having a plurality of tangentially disposed passages communicating with each chan'iber, and a iotor in said cylinder provided with tangentially disposed pockets adapted to communicate with the passages in said cylinder.
A power generator asin claim 1, where in the rotor pockets have overlapping portions and are placed in circninlerential sets in said rotor with the pockets corresponding in number to the passages of said cylinder.V
3. A power generator comprisi'g a cylinder having intake and exhaust ports and chambers circumferentially thereof', and a rotor in said cylinder having its periphery provided with short and lo-ng pockets, the long' pockets being in parallel planes be tween the planes of the short poclnitsv` said rotor having angularly disposed passages therein connecting the inner ends ot the long pockets to the inner ends of the short pockets, all of said pockets adapted to communicate with the intake and exhaust. ports and chambers of said cylinder.
f1. A power generator comprising a cylinder provided with intake and exhaust ports and transversely disposed chambers communicating with tangcntially disposed passages, and a rotor in said cylinder having' its periphery provided with tangentially dis! posed long and short pockets, the short pockets communicating with the long pockets and .adapted to communicate with the intake ports of' said cylinder7 the short pockets beingdisposed in a common plane, the long pockets being disposed in a common plane parallel to the plane ol the short pockets, and said long pockets overlapping each other with all of said pockets adapted to con'ininnicate with the passages and chambers of said cylinder.-
In testimony whereof I aflix my signature.
