30mm: ENGINE Application fil ed January 28, 1930. Serial Io. 454,015,
This invention relates to rotary engines and has: relation more particularly to a device of this kind adapled for usein connection with steam or other fluids; and it is an object '5 015 the invention to provide adevice of this character constructed in a manner to obtain maximum efliciency from the motive fluid.
Another object of the invention is to pro vide. a device-of this kind which in its asl sembly is compact without sacrifice of powcn An additional object of the invention is to provide a device of this kind comprising a stator-and a rotolgthe stator being divided. into a plurality of chambers and the rotor having a part working in; each of said chamhers, adjacent chambers being in communi cation one with the other whereby the motive fluid passes in succession from one chamber t the other; thus assuring, high efiic'iency.
The invention consists in the details of con. struction and in the combination and a1" rangeinent of the several parts of my inn proved: rotary engine whereby certain important advantages are attained and the de- 5 vice rendered simpler, less expensive and othc'rwise more convenient and advantageous for use, as will be hereinafter more fully set forth. p i Y The novel features of my invention will hereinafter be definitely claimed.
In order that my inveiiitionmay be the better understood, I will now proceed to de" scribe the same with reference to the accompanying drawings, wherein t-- Figure l is a View inside elevation of an engine constrl-icted in accordance with an embodiment of my invention, the side face plate being. removed; I
Figure dis a vertical sectional view taken 40 substantially on the line 2-2 of Figure I with both side face plates applied;
Figure 3 is? a side elevational iew ofrone oi the impellers as herein employed;
Figure & is a view in front elevation of the 46 impeller as illustrated in Figure 3;
Figure-5 is a sectional view'taken substan tially on the line 5--5 of Figure 2 looking in thedirectioni ofthe arrow; the rotor being omitted; I 1 V Figure 6 is n view inwtop plan of the in tel-nail Figure 7 is aview in side elevation of the partition or wall as illustrated in Figure 6;
Figure 8 is a sectional view taken substaqr 5:3 tially on the line 8--8 of Figure 1. As disclosed in the accompanying drawings, S denotes the stator comprising a substantially cylindrical shell or casing 1 having its end portions provided with the out' standing flanges 2', the lower portion of each i of such flanges being formed to provide a supporting means for the stator. It is to" be understood, however, that the stator may be held in desired working position in any way preferred.v c
Substantially midway the ends thereof the stator has tightly mounted therein a partition or wall 3 whereby the stator S is divided into two chambers X and Y, the chamber Y being of greater volumetric capacity than the chamber X The ends of the casing or shell 1 are closed by the end face plates or heads 4, each of which being shown as held in position by the removable threaded members or screws 5. k Each of the plates or heads 4: is also preferably provided atdiametrically opposed points with the inwardly directed pilot pins 6 for engagement within properly positioned openings 7 formed in an adyicent flange 2 whereby the roper application oi the plate or head 4 is facilitated It is to be understood that the screws 5 hereinbefore referred to are engaged with the remaining openings 7. o
Disposed through the stator S and sni ably supported by the applied plates or heads 4 and the partition or wall 3 is a shaft 8 from which power is adapted to be taken ofi in any manner desired. i c The opposed faces of the partition or wall 8 and the plates or heads l are provided with the outstanding circular bearing blocks 9 preferably integral with said heads and pertition or wall, These blocks 9 are coplanar 95 in a direction lengthwise of the shaft 8 and concentric to the center of the internal. chambars of the state! S.
Within each of the internal chambers of the stator S is trotor B comprising a rim l1 partition or wall of the StBtOI' IHIBP- i concentric to the shaft 8 and of a width to The rim 11 of each ofthestators is pro- Vided in its periphery and at diametrically opposedpoints with the transverse slot or groove 16 extending entirely thereacross and;
also extending down within the web 12.
-' Extending through each of these slots 16 is the-blade '17 "of an impeller A, said bladebeing of a width to snugly engage between the opposed facesof-the partition or wall 3 and a plate or- 'head 4' and'having its outer edge face sub'stantiall'y in contact at all times with the-internal peripheral wall of'the chamber of thestat'or in which-itope'rates.
One end portibnbftheblade 17 is pro v'ided 'with'an'inwardly disposed arm or shank l8 terminating in an annular member or'ring 19which is snugly engaged around a block 9 so that as the rotor revolves the blade 17 as a result of the coaction between a block 9" and the annular member or ring 19 will maintain thedesired contact of the outer edge of the-blade 17 withthe internal peripheral wall of the chamber in which the rotor is operating. This action,--how-ever, results'in "a slight rocking movement of the blade 17 and to compensate for this movement the slot '16 in which the blade 17 operates is gradually widened from its outer end in adirection inwardly of the rotor as is particularly illustrated in Figure 1. The opposed walls of the slot 16 ill-relatively close proximityto the periphery of the rim 11" 'carry-the rocking bars 20. As particu larly illustrated in Figure 1, each .of these bars'2O- h'as flat face constantly in contact with aflat side face of the blade 17. These bars 20 maybe madeof any desired material but preferably steel. These bars 20 constitute wear members and can be readily removed and replaced as the requirements of practice may necessitate. 4 v
I One of the chambers of the stator to one side of its vertical center has the casing or i v shell 1 provided with'an internalpocket'21 into which discharges a line 22 leading from a suitable source of fluid supply, such as steam, compresse'dair or water under pressure." v V This chamber of the'stator at the opposite side of its U vertical center is provided with a: second pocket 23 which communicates with a passageway 24' extendingthrough the up per portion of the partition or wall 3 in a direction substantially at right angles to its axial center. This pocket 23 registers with a circumferentially disposed pocket or recess 25 provided in that portion of the periphery of the partition or wall 3 coincident with the pocket 23.
The passageway or port 2% delivers within an internal pocket 26 in communication with the second chamber and at the same side of the vertical center of the stator as the pocket 21 hereinbefore referred to. This pocket 26 has in register therewith a pocket or recess 27 provided in the adjacent peripheral face of the partition or wall 3. This second chamber of the, stator has a second inwardly facing pocket 28 at the same side of the vertical center of the stator as the pocket 23. The pocket 28 has leading therefrom an exhaust pipe 29. I
Asthe fluid enters through the pipe line 22 its action will effect the desired rotation of rotor R in the first chamber and such fluid will pass out through the pocket 23 and passageway or port 24 and-through the pocket 26 into the second chamberfor' proper action upon the impellers in the second chamber of the stator, thus assuring a maximum of efficiency being obtained from the fluid.
From the foregoing description it is thought to be obvious that'a rotary engine constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and
it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason 1 do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed;
