ROTARY ENGINE.
sPEojIFIoATIoN forming part (if Letters Patent No. 732,880, dated July '7, 1903. Application filed March 13, 1902. Serial No. 97,971. (No model.)
To all whom it may concern: I
Be it known that I, JEROM S. MOSELEY, of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Rotary Engine, of which the following is a specification.
My invention has forits object the production of a rotary engine which is particularly simple in construction, economical in manufacture, and highly efficient and durable in use; and to this end it consists in the devices and combinations hereinafter set forth and claimed.
7 shown in their positions assumed at the com- Figure 1 is an edge view, partly broken away, of a preferred embodiment of my invention. Fig. 2 is an elevation of the rotary engine seen in Fig. 1,-a portion of the casing for the intermeshing gears being removed. Fig. 3 is a vertical sectional view taken on line 3 3, Fig. 1. Fig. 4 is a view similar to Fig. 3, one side of the casing of the engine being removed and the piston-disks being mencement of the entrance of the motive fluid. Fig. 5 is anelevation of the lower portion of the parts seen in Fig. 4, the pistonsaid casing Fig. 3.
disks being shown in their positions assumed when theirprojecting arms are about to enter the cut-outs exteudinginwardly from the peripheries of said piston-disks. Figs. 6 and 7 are face views of the inner-sides of the sections of the casing of my engine, a portion of beingshown in section in Fig. '7. Fig. 8 is a sectional view taken on line 8 8,
-My rotary engine consists, essentially, of a casing A and piston-disks B B. The casing A is of any desirable form, size, and construction, is preferably composed of separable sections ac, united by suitable securing means a and isprovided with two substantially cylindrical parallel chambersa a merging together at contiguous sides, and inlet and outlet ports a a having diverging branches a a communicating with the chambars a a at opposite sides of their point of of the chambers a (1 than the contiguous ends of the grooves 01 in order that-said grooves a" or may conduct the motive fluid to the passages, presently described, of both piston-disks B B at substantially. the same time.
The piston-disks B B are supported, respectively, in the chambers a a and are arranged substantially concentric therewith, and, as best seen in Figs. 4 and 5, their peripheries roll in contact. Said piston-disks B B are each provided with a cut-out b, extending inwardly from its periphery, an armabutment b, projecting from said periphery and movable in engagement with the inner face of the corresponding chamber and into the cut-out of the opposite piston-disk, and a passage b ,opening through opposite sides of said piston-disk in alinement with the inletgrooves at a in the opposite walls of the corresponding chamber and also openingthrough the rear wall of said arm I). The cut-outs b and the arms I) are so relatively arranged that at the commencement of the entrance of the motive fluid the arm b of the piston-disk B is nearer the point of union of the chambers a a than the corresponding part of the piston-disk B, and consequently said arms I) readily enter the cut-outs 1) without any interference with each other.
The piston-disks B B are suitably connected to driving-shafts B provided with intermeshing pinions B which are arranged in a casing B and operate to cause the arms I) to always register with the cut-outs b. I
In the operation of my rotary engine the motive fluid admitted through the port (1 passes through its diverging branches at and the grooves a a to opposite sides of the piston-disks B B and thence through the pas- 1 sages b to the rear of the arms '5, effecting rotation of the piston-disks. As saidpistondisks continue their movement the inlet-openings of the passages 19 are rotated beyond the grooves a a whereupon the entrance of the motive fluid is cut 0E, and said motive fluid previously admitted within the chambers a a is then used eXpansively until the arms b pass the diverging branches a of the port a and permit said fluid to exhaust through the port a. The friction incidental to the rotation of thepiston -disks is reduced toa minimum,
owing to the rolling of said disks upon each other and the admission of the motive fluid,
therewith, said piston-disk being provided with an arm projecting from its periphery and engaging the inner face of the chamber and with a passage leading from opposite sides of said disk through the rear face of said arm, means for conducting the motive fluid to opposite sides of said passage, substantially as and for the purpose set forth.
2. Arotary engine comprisinga casing having two chambers therein,a piston concentrically mounted in each chamber, said pistons having their peripheries in contact and provided with abutments arranged one in advance of the other, steam-passages having their outlets arranged one in advance of the other, and steam-inlet passages for each chamber in said casing having their discharge-openings into the chambers arranged one in advance of the other, substantially as described.
3. In a rotary engine, the combination of a casing having two chambers, a piston mounted in each chamber having an abutment, the abutmentof one piston being arranged in advance of the abutment of the other, steampassages in each piston opening out through the sides thereof in radial alinement with its abutment, and a steam-passage in each chamber coact-ing with the passage in the piston associated therewith, the passage in one of said chambers having its outlet arranged in advance of the outlet'end of the passage in the other chamber, substantially as described.
4. A rotary engine comprising two substantially cylindrical parallel chambers merging together at contiguous sides, two piston-disks supported respectively in the chambers and arranged substantially concentric therewith, said piston-disks having their peripheries in contact and being each provided with a cutout extending inwardly from its periphery, an arm projecting from said periphery and movable into the cut-out of the opposite piston-disk, and a passage opening through op posite sides of the piston-disk and the rear face of the arm for conducting the-motive fluid to the rear of said arm, and arc-shaped grooves in opposite sides of each chamber for conducting the motive fluid to the passage of the corresponding piston-disk, substantially as and for the purpose set forth.
5. A rotary engine comprising two substantially cylindrical parallel chambers merging together at contiguous sides, two piston-disks supported respectively in the chambers and arranged substantially concentric therewith, said piston-disks having their peripheries in contact and being each provided with a cutout extending inwardly from its periphery, an arm projecting from said periphery and movable into the cut-out of the opposite piston-disk, and a passage for conducting the motive fluid to the rear of the arm, and inlet and outlet ports having diverging branches communicating with the chambers at opposite sides of their point of union, substantially as and for the purpose described.
6. In combination, a casing having companion chambers, and a piston provided with a radial abutment concentrically mounted in each chamber, said casing having a central inlet-passage provided with branches leading therefrom contained wholly within the side walls thereof, said branches terminating in passages opening out through said side walls and extending concentric to the axes of the pistons, substantially as described.
7. In combination, a casing having companion chambers, and a piston provided with a radial abutment concentrically mounted in each chamber, said casing having a central inlet-passage provided with branches leading therefrom contained wholly within the side walls thereof, said branches terminating in passages opening out through said side walls and extending concentric to the axes of the pistons, one of said branches opening out in one of said piston-chambers a less distance from said central inlet than the other branch, substantially as described.
In testimony whereof I have hereunto signed my name, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 1st day of October, 1901.
