ROTARY ENGINE.
SPECIFICATION forming part of Letters Patent No. 388,522, dated August 28, 1888.
Application tilcd February 18, 1888.
To all 1071 0727, it um y con/corn:
Be it known that I, Josnrrr I antican- MIN, of Sore], in the county of Richelieu, lroviuce of Quebec, and Dominion of Canada, have invented a new and Improved Rotary Engine, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved rotary cngi ne which is simple and durable in construction, very effective in operation, and adapted to be operated by water, air, or steam.
The invention consists of certain parts and details and combinations of the same, as will be fully described hcreinat'ter,and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation of the improve ment, partly in section, on the line a: x of Fig. 2. Fig. 2 is an end elevation of the same with parts in section. Fig. 3 is a sectional side clevation of the improvement on the line 1 I/ of Fig. 4. Fig. 4 is a sectional plan view of the same on the line 5 z of Fig. .3. Fig. 5 is a face view of the cylinders and their axle. Fig. ti is a like view of the driving'wheel and its casing, parts being in section. Fig. 7 is an end elevation of the valve. Fig. 8 is a longitudinal sectional elevation of the same on the line 10 w of Fig. 7. Fig. 9 is an end elevation of the same, and Fig. 10 is a sectional end elevation of the same on the line a a of Fig. 8.
The improved rotary engine is provided with a casing, A, made in two parts, land U, of which the part, lis provided with an eccentric hub, 1;, held in a standard, X, and the part 0 is provided with a central hub, (7, held in a standard, X, located opposite the stand ard X. The hubs I3 and C are made hollow, and the hub ll supports a trunnion, I), on the inner end of which is secured a hub, 1), provided with a valve-seat, l V, i n which are formed the ports a, a, u), and a", and on the said huh I) are secured radially-extending cylinders I E, E, and F", placed at right angles to each other. Into the said cylinders open said ports a, a, a and a", respectively.
On the valve-scat 1) is held a fixed valve, F, provided with an inlet-port, b, registering Serial No. 261,471. (No model.)
alternately with the ports a. a, u, and a when the hub 1) is rotated. In the inner side of the val vc F is formed a U-shapcd exhaustport, 0, adapted to connect by one end successively with the said ports (1 a, (1?, and a, and the other end of the said exhaust-port 0 leads to a central opening, (1, formed in the valvc-seat I)". The central opening, (1, leads to an exhaust chamber, D, formed in the huh I), and from the said exhaust-chamber I) lead the openings (1 into the interior of the casing A,which thus forms a receptacle for the exhaust-steam. Into the casing A leads a pipe, for'carrying off the exhaust-steam to any convenient place.
The valve F is secured to one end of a pipe, F, passing through thehollow trunnion l) and through the hub t of the casing ll. The outer end of the pipe F is connected with a suitable source of steam, water, or air supply, and on the said outer end of the said pipe F is secured an arm, F", for turning the said pipe, so as to reverse the motion of the engine whenever desired.
The inner end of the pipe F leads to the openings c,for1ncd in the cylindrical extension F, secured to the outer face of the valve F. Said openings 0 are adapted to be opened and closed by a governor-valve, t provided with a cap, G, held to slide on the said extension F and on the said cap (1' is formed an inclined annular flange, (i engaged at opposite sides by a slot, H. formed in the slide H, passing through a slot in the offset D, formed on the huh I) and carrying the said governorvalve G. Each slide extends into a cylindrical offset, D secured to the huh I), and on the outer end of the slide H is fastened a weight, HF, held to slide in the said offset 1) and pressedinward by a spring, I, resting with one end against the said weight ll and with its other end against the setscrew J, screwing in the said offset 1) and serving to regulate the tension of the spring I. A pin, G, engages a central recess in the cap (H of the valve (i, so as to guide the latter in the offset D, and the said pin (1 projects from a disk, l, held in the outer end of the said offset 1).
In the cylinders E, 10, E", and W are held to slide the pistons K, K, K, and K, respectively, each being provided on its outer end with a plate, L, held to slide in a groove, N, formed in a wheel, N, said groove extending at right angles to its piston. K, K, K and K is arranged a central opening, K, through which a fluid can pass into the recess L, made in the outer face of the plate L, which is of about the same area as the piston, thus forming a cushion between said plate L and the rear wall, N, of the wheel N, which wall forms a back for the plate L. The wheel N is provided with a central ofl'set, N from which extends outward a shaft, N, having its bearing in the hub G of the part O of the casing, and carrying on its outer end the pulley 0, connected by a belt with the machinery to be driven.
The operation is as follows: A suitable fluid under pressure may be used to operate the machine. Preferably,however,steamisemployed. \Vhen the machine is in the position shown in Fig. 4, the fluid enters the pipe F and passes through the openings einto the offset 1) of the huh I), and from the latter through the port b in the stationary valve F to the port a in the valve-seat D entering the cylinder E at its bottom and exerting its pressure against the piston K, and then enters through the central opening, K in the recess L, which balances the pressure of the piston K, and then exerts its pressure against the back N of the wheel N, so that the latter is rotated, as it is eccentrically placed in relation to the hub 1), carrying the cylinders E, E, E, and E" and their pistons K, K, K", and K", respectively. The wheel N on being rotated carries with it the piston K, as the plate L, secured to the latter, travels in the slot N of the wheel N. The piston K thus also imparts a rotary motion to the huh I), as it is held in the cylinder E, secured to the said huh I). and when the latter is retated its port a is finally out off from the fluidinlet port I); but the next port, a or a", according to the direction in which the engine is running, then registers with the port b and the fluid is admitted to its respective cylinder. The same operation against the respective piston now takes place, as above described, so that a new impulse is given to the wheel N. XVhen the respective cylinder is in its inner most or outermost position,the plate L stands in the middle of the groove N as shown in Fig. 3. \Vhen the piston K, K, K, or K is nearing its outermost position, the port a, a, a", or a, respectively, registers with the U-shaped exhaust-port 0, so that the fluid on the return movement of the piston can pass through the ports aand 0 into the central port, (1, of the hub D, and then the fluid passes into the chamber D, and from the latter through the openings d into the interior of the casing A, from which the exhaust can escape through the pipe 0. Thus it will be seen that the cylinders E, E, E, and E alternately take the fluid under pressure through the port I), a, a, a", and a respectively, when the pistons K, K, K, and K are in or near their innermost position. Theexhausttakesplacesuccessively from the cylinders E, E, E and E when the pistons K, K, K, and K are in or near their In each piston l outermost position, as above described. The amount of fluid under pressure passingthrough the pipe E into the oflset I) is regulated by the governor-valve G, which, with its cap G, slides on the offset F so as to cut off part of the openings 0 whenever the speed of the engine increases over the normal speed. The governor-valve is operated on automatically by the slides II, which move the said valve G forward or backward on the oflsct F by the weights 11*, which move outward on an increase of speed of the engine and move inward on a decrease of speed. The inward or outward movement of the slides II causes a forward or backward movement of the valve (i as the latter, with its inclined flange G", travels in the inclined slots H of the said slides ll. it is understood that the weights II are moved outward by the centrifugal force, on the increase of speed of the onengine, andmoveinward correspondingly by a decrease of speed and by the action of the springs I. The tension of the latter is regu lated by the set-screws J, so as to set the governor-valve (r at whatever point of cutoff may be desired on the openings 6. The rotary motion of the wheel N is transmitted to other suitable machinery by the pulley O, or other suitable means, such as gearwhecls and the like. When it is desired to reverse the engine, the operator turns the handle or lever F the way he wants the engine to run until the inlet-port I) of the valve 1* has traveled its length and the length of the port (I, so that the port 1) opens when the engine runs the other way.
It will be seen that the fluid under pressure is admitted to the cylinders E, E, E", and E successively and in a manner similar to that used in the common slide-valve engine, and the exhaust takes place in a like manner.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
