ROTARY ENGiNE.
SPECIFICATION forming part of Letters Patent No. 377,364, dated January 3l, 1888.
.Application filed August 17, 1886. Serial No. 211,094.
(No model.) Patented in Germany March, 1886, No. 37,424; in Italy December 111, 1886, No. 20,627; in Belgium December 15, 1886. No. 74,756, and in France February 7, 1587, No. 178.895.
T0 all whom, t may concern,.-
Be it known that I, PHILIP Janns XVEBER, of NeuOetting, Bavaria, Germany, have invented a new and Improved Ilotary Engine, (for which I have obtained the following Letters Patent: Geitnany,No. 37,424, dated March 28, 1886; France, No. 178,895, dated February 7, i887; Italy, No. 20,627, dated December lil, I886,and Belgium,No. 74,756, dated December 15, 1886,) of which the followingisa full, clear, and exact description.
rIhe nature of my invention consists in the arrangement of three or more pistons in the cylinder, revolving` concentrically behind cach other, connected to an axis passing through cach other, to transmit motion to a drivingshaft placed eccentrically to the cyliudershafts. Vhen motion is applied outward, the pistons can act as pumps or blowers.
rlhc invention consists of the various improvements hereinafter more fully described.
In the accompanying drawings, Figure I is a vertical crossscctiou through the cylinder, and Fig. II is a longitudinal section of the same.
A is a cylinder attached to a bed-plate, and provided with exhaust-passage e and inletpassages p, closed by a suitable slide-valve, h. The valve 1L is inclosed in a case, I3, in the usual manner. A is the cylindencover. The other end of the cylinder is cast solid and provided with along hub, A2. In the cylinder three or more shafts, cl, b c, are arranged, the central shaft, c, having a bearing in the cylinder-cover A', and the two other shafts, b a, being hollow, the shaft b passing over the shaft c and the shaft a passing over the shaft b. The shaft c extends in the cylinder through the whole width of the saine, while the shaft b extends only two-thirds into the cylinder and the shaft a only one-third. To the ends of these shafts the hubs of the pistons c', b', and a/ are secured, the piston c' extending over the hubs ot' the pistons b a, the piston b over the hubs ofthe pistons a and c', and the piston a over the hubs of the pistons b c', so as to fill the annular space between the respective hubs and the inside of the cylinder. At the outer ends the shafts a b c extend likewise some distance past each other, sufficient to receive the hubs of 5o their respective cranks a, b2, and ci. (See Fig. II.) The ends of these cranks a2, b2, and et are connected through rods r r r2 with pins s s si, secured in a wheel, \V, fast on the driving-shaft V, placed eccentrically to the shafts 55 a b c. The cranks a2 bl c2 are describing with their pins a circle which is less in dianieter than the circle which is described by the pins s s s?, lso that the first circle is almost wholly lyingI within the second. The different sizes 6o of these circles, combined with the application of more than two pistons, cause the avoidance of the dead-points in the rotary motion.
The end surfaces ofthe pistons are provided with the usual elastic packing-strips, a, such 65 as india-rubber or canvas. (Shown in dotted lines in Fig. II.) To facilitate the fitting of these elastic packings, each piston is provided with two side pieces, m m', ground to tit against the hubs of thc adjoining pistons and against 7o the inner surface of the cylinder, and secured to the body of the piston by screws 0*. When these elastic packings a pass the inlet-openings, they will be affected by the pressure and become ineffective. To obviate this difficulty, 75 packing-plates 7c are fitted into the end surfaces of the side pieces m next the cylindersurface, connected by the passages k with the interior ofthe cylinder. The steam, entering these openings 7c', will act upon the packing- 80 plate 7c, and forms thus a tight packing before the elastic packing is affected by the action of the steam-pressure.
To form always a tight fit between the hubs of the pistons ab c', as well as between the 85 ends of the hubs and pistons and the ends of the cylinder, a ring or disk, e, is fitted against the end of the hub of piston c, and a recess in the ring or disk c is provided with suitable packing, f.
The inlet-passage p is divided into a number of channels or passages closed more or less by the slide-valve h. At the same time the following piston (0 in Fig. I) can sooner or later shut oif the steam to the preceding piston, 9 5 (a in Fig. I,) according to the greater or less covering of the slide-valve 7L.
In Fig. I the piston c is just about to shut off the steam :from piston a. A further motion and piston c will receive the full action of the steam or other pressure, While piston a. operates then onlyby the action of the expan` sion of the steam. By connecting vthe slidevalve h with a suitable governor the motion ofthe pistons, and consequently of the driv- Ying-shaft V, can be regulated.
`is necessary that at any moment at least one piston is occupying a position favorable to the rotary motion. vWhen all pistons are at the same timein unfavorable positions, there results a dead-point, which recurs in each rotation as many times asl there are pistons.
The advantages of the construction herein described are due to thepeculiar relation between the circles described by the cranks of the pistons and by the pins s s s2 of the driving-shaft-that is, to the fact that the circles described by the cranks of the pistons are much smaller or much larger than the circles described by the pins of the driving-shaft.
I am awareof English Patent N o. 1,569 of 1853, which shows a rotary engine so constructed that the circles described by the pistoncranks are of the same diameter as the circles described by the driving-shaft cranks. In this construction, therefore, all the three pistons will at times occupy positions unfavorable tothe motion of the driving-shaft, and thus dead-points will occur. This construction I do not claim; but f I do claim 'as my inventionl. The combination, in a rotary-engine, of three or'more revolving pistons, which are with their shafts set centrally one Within the other in the cylinder, with the driving-shaft outside of the cylinder and lying eccentrically thereto and receiving` rotary motion from the pistons, all being so constructed that the crankpins describe a circle much less or much greater in diameter than the circle described by the pins of the-driving shaft cranks, substantially as specified. p
-2. In combination with the pistons rotating in a cylinder, A, the side plates, m m', with packing la in the plate m, connected through passages lc with the interior of the cylinder,
substantially as specified.
3. The combination of cylinder A and pistons abcQprovided with packing nk, and side plates, m m', With the head A and disk e, containing packing j', substantially as described.
