SPECIFICATION forming part of Letters Patent No. 531,246, datedDecember 18, 1894.
Application filed March 8, 18947. Serial No. 502,799. (No model.)
To aZZ whom, #may concern.- Y s i Be it known that I, OLIVER ARNOLD, a citizen of the United States, residing at Leicester,
Y gether with the accompanying drawings, is a specification suiiiciently full, clear, and exact to enable persons skilled inthe art to which this invention appertains to make and' use the same.
The object of my present invention is to provide an economical and efficient rotary motor'or engine adapted for operation either by steam, compressed air, water or other fluid under pressure; said motor provided with a system of sliding gates for receiving the motive force, with gate-actuating devices automatically controlled by pressure of the Voperating medium for bringing said gates into their operative and non-operative positions al1 arranged as more fully, hereinafter explained. These objects .I attain by mechanism constructed and organized for operation in the peculiar manner illustrated in they drawings, Wherein n Figure 1 is a vertical section perpendicular to the axis of rotation. Fig. 2 is aver# tical section longitudinal to the axis. Fig. 3 is a sectional view showing in detail one set of the operating parts. Fig. 4 is a face view of a portion of the lrotator head. Fig. 5 is a transverse section at line mon Fig. 3, showing the detail of the movable gate. Fig. 6 is a transverse section atline w w on Fig. 3, showing the detail of the actuator piston and the barrier. Fig. 7 is an exterior side view, and Fig. 8 is an exterior end view.
Referring to parts, A A denote the body, shell or frame of the motor, consisting of a circular or ring-shaped casing A lprovided with a base-foot or means for its stationary supportupon a suitable bedB, and side-plates A fitted' to and secured by'fscrew bolts upon the opposite parallel sides of said circular casingA;-these parts together forming or inclosing a cylindricalfchamber within which the operating mechanism is arranged, the same being mounted on a central axis or shaft C that turns in bearings a formed on the side plates A. The end of the shaft extends outside the casing and is provided .with apulley C2 or other suitable means for transmitting motion therefrom,`as required. The 4shaft C can beY provided with supporting bearings separate from the plates A when desired.
YThe ring casing A is provided with oppositely disposed inlet ducts or ports D and a corresponding number of exit passages E, which connect respectively with suitable snpply pipes D and discharge pipes E which can be arranged as shown, or in any convenient manner.
F indicates the rotator-head or power-wheel having a rim formed of such dimension that it will fit the interior of the, shell between the side-plates A closely, but so asV to allow it free running action; said rim being connected by a web or arms with a central hub supported and fixed upon the shaft C so that the rotator and shaft will turn together.
A circumferential channel G is formed about the periphery of the rotator between projectingV anges or annular side-plates f that diametrically fill the circle of the ringcasing A. The channel G serves as a space for the steam or actuatingiluid by which the motor is operated, and communicates directly with the inlet ports D and exhaust passages E.
Between each of the exhaust passages E and the next adjacent inlet port D there is a barrier Hrigidly fixed on the rin'gcasing A, and. extending inward so as to completely obstruct the channel passage at that position without interfering with the motion of the rotator-head. y Arranged at intervals about the rotatorhead there is a series of radially movable in- The inner ends of said pistons J are respect-k ively connected with the corresponding gatestems vby means that will impart an outward movement to the gate I by inward movement of the piston, and vice versa. The area of the face of the piston .I is made of such proportion, relatively to the area of the gate-stem, that it will receive preponderance of pressure sufcient to move the gate with the required degree of celerity.
The gate I and its actuator J are best shown in detail in Figs. 3, 4, and 5. Said parts are connected, by pivoted links fn or otherwise, with a rocker K having its fulcrnm or axis K carried on the rotator wheel; said rocker serving to transmit the motion of the pressure piston to the gate-stem and gate. A suitable spring L is preferably combined with the rocker to normally press outward the piston .I or retract the gate I; and a stop M, adjustable or otherwise, is provided for limiting the extent of movement of the parts. In the drawings Fig. 1 the spring is shown in two forms. The spring and stop are omitted ou some of the actuating sets, as either form may be used when preferred. When at outward position the face of the piston .I is flush, or nearly so, with the face of the rim or bottom of the channel G, (see Figs. 3 and 5) but not protruding. Hence it will pass the barrier I-I closely without interfering therewith.
In making the rotator F the rim is first formed with the narrow flanges f', and the pockets I2 then made therein by cutting transverse grooves across the rim. Then byiixing to the edges of the rim the annular platesf the ends of the slots are closed andcomplete pockets produced for the receptionof the bars or gates I; the spaces f2 cut in the tlangesf serving as radial guide-ways for the ends of the gate, while the front of the gate slides against the side of the recess. best provided with a packing strip t' along its outer edge where it strikes the inner surface of the casing. Small passages m formed at the back of the gates in the rear edge, and
leading to the bottom of the pockets I2 elects equalization of pressure belowand above the gate, so thatthe gate will move without undue resistance. The gate stem I and the actuating pistons .I can be provided with suitable packings P when desired.
An outlet or ventpipe o is provided from the interior of the rotator for the purpose of overcoming the effect of any leakage thereinto, and for maintainingnormal atmospheric or low pressure within the central space of the rotator-head.
The rin g-casing is preferably provided with inwardly inclined guides e at the exit passages in front of the barriers II, which` guides insure the retractive action of the gates` I as they approach said barriers and avoid,` any lia.
bility of derangement by non-action of the reciprocating parts. Plates Il2 attahed to the casings A at the exhaust passages serve for attachment of the pipes and for the connection to the circle when the casing is formed in separable parts.
The rocker devices at K, for connecting the The gate I is piston J and gate I, can be of any convenient form suitable for transmitting and transposing the inward movement of the piston to exert an outward movement of the gate, and
vice versa, by pressure of the steam or operating medium.
In my improved motor, as shown, I provide two barriers Il, two sets of inlet-ports D and exhaust-passages E, which are severally disposed within the circular-casing; diametrically opposite each other in pairs; and with these I employ four sets ofintercepting gates I and actuatolpistonsmJ in the rotator-head, it being essential to have two such gates representing each inlet-port, so that at least one of the gates will at all times be at outward position of adjustment, to intercept the passag'e of the steam or iuid in the channel G, between each inlet D and outlet E; thus balancing the action and pressures of the motive forces at opposite sides of the axis, and producing a better, more powerful and elliciently operative mechanism. It will however be understood that if in any instance desired the motor engine can be provided with a greater number of inlets, barriers and exit passages, and the rotatorhead furnished with a correspondingly increased number of intercepting gates and pressure actuated pistons, the sets of mechanism being each arranged in operative order substantially as those above described.
By increasing the number of inlets, barriers, exits, and intercepting gates the power of the motor is increased proportionally without increase in the sectional area of the channel G or material increase in the quantity of steam required for operating a rotator of given dimensions at a given speed of rotation; since the pressure acts upon a separate gate from each` inlet with equal force for driving the rotator, while the volume of steam used for each revolution equals only the capacity of the channel G whether two, four or more sets of inlets and gate mechanisms are employed in the circle of the rotator.
In the operation, the steam, water, or other medium entering under pressure at D D fills the space G, and its pressure acting upon the reciprocating piston J forces the same inward moving the rocker K and thereby projecting the gate I outward across the channel G and against the ring casing A; thus confining the steam between the gate I and the barrier I-I,` and the latter being rigidly Iixed to the casing the energy is exerted in moving forward the gate I and thus rotating the head Fin the direction indicated, according to the degree of pressure and proportional area of the gate surface; and this motion is` transmitted through the center shaft C to the drive pulley. AAs the first gate is carried forward a second gate passes the barrier II and as its actuating piston emerges from beneath the barrier to the steaminlet space it is instantly depressed and the second gate projected across the channel G to take the pressure of TOO IIC
the in-iowingsteam. This second gate cuts off the pressure from the first described gate,v
. the gate retracted into its pocket I in timeto drical chamber its circular casing having two pass the second barrier H Without interfering therewith.
In a manner similar to that here described the several gates and their actuating pistons pass the respective barriers and are consecutively brought to their outward position for holding the steam or Huid pressure andreceiving the motive force until a following gate is projected; then discharged and retracted while passing the exitduct and adjacent barrier and again thrown outward in their order as the rotator head is impelled forward, thereby producing a rapid and powerful rotation of the motor shaft and drive pulley.
lThe operation of a gate by means of a pressure-actuated piston connected therewith being old, I do not claim such feature broadly as of my invention.
I claim and desire Patent- 1. In a rotary motor the combination, as hereinbefore described, of the'inclosed cylinvto secure by Letters opposite barriers fixed on the interior of its circle, the induction and eduction ports opening to the interior adjacent to the front and back of said barriers, and disposed diametrically opposite each other, in pairs; the circumferentially channeled rotator-head .with the series of radially sliding gates and pressure-actuated gate-operating pistons therein, disposed atintervals that represent tWo gates relatively to each inlet, the leading gate sustaining the working pressure until, by the pressure exerted upon its actuating pistons, the following gate` is fully projected for controlling the channel, as set forth.
2. The rotary motor herein described, comprising the circular casingrprovided with a plurality of induction ports and exhaust passages, oppositely disposed in pairs within the circle, a plurality of inwardly projecting barriers fixed to the casing respectively adjacent to the induction ports and obstructing the steam channel, the rotator-head having a circumferential channel and flanged rim, its periphery fitting within said circular casing, the series of transverse pockets formed in said rim and radially sliding gates therein disposed at intervals that represent two gates to each inand stopsthat limit the movement` of the rockers and connected parts, all substantially as set forth.
3. In combination, as described, the inclosing casing formed of the ring portion, with close fitting side plates completely inclosing the rotator, the rotator head adapted for peripheral application of the motive force, radially sliding gates and pressure-actuated gateoperating pistons workin g in the rotator rim, and the relief-pass or means for exhausting the central space within said rotator-head, as set forth.
4. Ina rotary motor h/aving its rotator-head face of said rotator-rim, substantially as set forth.
