TED STATES WILLIAM J. KREIMER, OF ST. LOUIS, MISSOURI.
ENGINE.
Original application filed July 14, 1920, Serial No. 396,313. Divided and this application filed November To all whom it may concern:
- Be it known that I, WILLIAM J. KREIMER, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Engines, the same being a division of my pending application Serial No. 396,- 313, filed July 14:, 1920, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to certain improvements in engines and has relation more particularly to a device of this general character of a rotary type and wherein the rotor is caused to operate under the influence of a fluid under pressure, and it is an object of the invention to provide a device of this general character including a rotor of a novel and improved construction whereby the requisite operation of the engine is effected.
Another object of the invention is to provide a novel and improved device of this general character including a stator and a rotor and wherein the stator comprises two relatively movable sections enclosing the rotor, together with yieldable means for constantly urging the sections of the stator one toward the other.
The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved engine whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise o more convenient and advantageous for use,
as will be hereinafter more fully set forth.
The novel features of my invention will hereinafter be definitely claimed.
In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:
Figure 1 is a view in side elevation of an engine constructed in accordance with an embodiment of my invention; Figure 2 is an enlarged vertical sectional view taken through the device as illustrated in Figure 1 and taken substantially on the line A--A of Figure 4;
Figure 3 is a fragmentary sectional view Serial N0. 515,028.
taken substantially on the line 33 of Figure 2; and
Figure 4 is a sectional view taken substantially on the line 4-4: of Figure 2. As disclosed in the accompanying drawings, 1 denotes a supporting base or foundation of requisite dimensions and which is provided adjacent one end with the supporting structure A including two transversely spaced and horizontally disposed members 2 arranged substantially in parallelism. The structure A supports a stator S annular in form.
The stator S comprises two sections 3 and 4. The outer marginal portion of the section 4 is provided with an annular groove or channel 5 in which is slidably engaged the peripheral wall 6 integral with the section 3. The opposed faces of the sections 3 and 4 adjacent their inner margins are provided with the annular grooves or channels 7 to be hereinafter more particularly referred to.
The rear portion of the peripheral wall 6 below the horizontal center thereof is pro vided with eduction or exhaust opening 8 and the upper portion of such wall to one side of its vertical center is provided with an induction or inlet opening 9. In communication with the induction or inlet opening 9 is a pipe or conduit 10 leading from a suitable source of fluid under pressure. Interposed in the pipe or conduit 10 is a regulating valve 11 of any preferred type.
Rotatably supported by the members 2 is a transversely directed shaft 12 eccentric to the axial center of the stator S and which is provided at one end portion with the pulley P or the like for the transmission of power. Also supported by the members 2 are the transversely alined circular trackways 14, said trackways 14. being eccentric with respect to the shaft 12 and concentric to the stator S and arranged inwardly of the members 2.
Extending within the stator S through the inner open face thereof is an annular member 15 provided adjacent its inner face with the oppositely directed annular flanges 16 which engage within the grooves or recesses 7 hereinbefore referred to.
Connecting opposed portions of the member 15 at opposite sides of its center are the trackways 17 arranged in parallelism. The central portions of the trackways v17 are connected by the transverse member 18 and said member 18 midway its length is provided with a hub or bearing 19 fixed tothe shaft 12.
Slidably mounted between the opposite end portions of the trackways 17 are the blocks or heads 20. Each of theblocks or heads 20 is provided with a forwardly disposed extension 21 extending inwardly of the stator through an opening 22 suitably disposed through the member 15. The outer end of the extension 21 is provided with a substantially semicircular recess 23 in which is seated a member 24 having its outer face disposed on such configuration as to have snug contact with the inner face of the peripheral. wall 6 and in a manner whereby leakage is substantially eliminated.
The periphery of the member 15 is provided circumferentially therearoundwith a L groove or channel 25 in which seats an in:
wardly directed flange 26 carried by' each of the arcuate members 27. The members-27 are of a length to snugly fit between the extensions 21 of the heads 20 at opposite sides thereof and are positioned within the stator S and the ends of said members 27 are engaged as at 27 to provide increased bearing surfaces for the extensions 21 and-in order to receive said enlarged portions 27, the adjacent portions of the member 15 are cut away in a manner to snugly receive such portions 27 I The peripheral portions of the members 27 are adapted to have contact with the inner face of the peripheral wall 6 at a point in advance of the induction or inlet opening9 and each of said members is yieldingly held in applied position through the medium of an inwardly disposed pin 28 arranged substantially centrally thereof and which is disposed through an opening 29'provided in the member 15. The free or inner end of the pin 28 is provided with a head 30 and interposed between said head 30 and the adjacent face of the member l5is an expansible member 31 herein disclosed as a coiled spring encircling said pin 28. I i 1 Each of the heads 20 inwardly of but in close proximity to the member'15 is provided with an elongated opening 32 having its major axis extending longitudinally of the head. Arranged in each of the openings 32 for limited sliding movement longitudinally thereof is a block 33. The inner end portion of the block 33 has extending inwardly therefrom a pin'34 directed through an opening 35 in the'inner portionof the head 20. The free or innerend of-the' pin 34 is provided with a head 36 and interposed between said head 36 and the adjacent end portion of the head 20 is an expansible member 37 herein disclosed as a coiled spring encircling the pin 34. The member or spring 37 serves to constantly urge the block 33 inwardly.
Disposed through each of the blocks 33 at substantially the center thereof is a transversely directed pin 38 capable of rotary or rocking movement. Carried by the opposite ends of the pin 38 is an arcuate shoe 39 riding on a track 14 as is particularly illustrated in Figure ,2.
The member 15 and the parts movable therewith constitute the rotor and as the fluid under pressure is delivered into the stator S through the induction opening or inlet port 9, the extensions 21 of the heads 20, together with the members 24, operate as abutments whereby the desired rotation of the rotor is effected. As a member 24 passes over an opening 8, the fluid is permitted to exhaust.
The sections 3 and 4 of the stator are con stantly urged inwardly one toward the other in order to maintain the requisite contact between the rotor and the stator, yet said connections are capable of yieldable outward movement. As herein disclosed, this connection between the sections 3 and 4 of the stator S is accomplished in the manner-par- '7 ticularly illustrated in Figure 3.
At substantially diametrically opposed points, the sections 3 and 4 are provided with the outstanding and transversely alined ears or extensions 40. In threaded engagement with one of the extensions 40 is the head 41 of a transversely disposed shank 42, the opposite end portion of said shaft being rotatably held by a lug 43 comprised in a bracket 44 carried by the second section 3. This end portion of the shank 42 has fixed thereto a pinion 45. The pinion 45 meshes with a rack 46 supported for sliding movement by the bracket 44. The rack 46 is provided at one end with a stem 47 slidably disposed through an end 48 of the bracket 45 and terminates in a head or enlargement 49. Interposed between the enlargement or head 49 and the adjacent end 48- of the bracket 44 is an expansible member 50 herein disclosed as a coiled spring encircling the extended portion of the stem 47 whereby the shank 42 is constantly urged in one direction about its axial center and in a direction to constantlyurge the sections 3 and 4 one toward the other. 1
