To all whom it may concern a citizen of the United States, residing at Cadillac, in the county of Wexford and State of Michigan, have invented a new and useful Engine, of which the iollowmg s a specification.
The present invention appertainsto engines, and aims to provide a novel and 1m-' proved engine operated by any siutable expansion or'pressure fluid. I i It is the object of the invention to provide an engine of such construction and operation, that the engine not only operate in an efficient and des1ra'ble manner, but will also operate without the usual pounding, jarring and vibrations incident in the operation of an ordinary englne, the present engine being balanced so as to operate smoothly and with little thrust against the supporting frame. With the foregoing and other objectsin view which will appear-as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, that changes in the precise embodiment of theinvention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the 1nvention. V
The invention is illustrated in the accompanying/drawings, wherein Figure 1 is a side elevation of the improved engine, portions being broken away. Figs. 2 and 3 are cross sectional views taken on the lines 22 and 3-8, respectively, of Fig. 1. Fig. 4. is a longitudinal section taken on the line H of Fig. 1.
In carrying out the invention, there is provided a cylinder 1 of suitable length and diameter, and having crank casing 2 at one end in which the crank shaft 3 is journaled for rotation, said crank shaft having an intermediate crank 1 and a pair of cranks 5 at the opposite sides of the crank 4. The cranks a and 5 project in opposite directions. The engine embodies a second cylinder 6 of suitable length and diameter alining with and spaced slightly from the cylinder 1, and an annular casting or coupling 7 is secured to the adjacent ends of the cylinders for spacing them apart and rigidly connecting them. The casting 7 has the it being understood opening 8. A piston 9 is mounted for re ciprocation within the cylinder 1 adjacent thecrankcase 2 and is connected by a connecting rod or piston 10 with the crank 4:. A second piston 11 is mounted for reciprocation within the cylinder 1 remote from the crank case 2. The cylinder 6 also has a pair of pistons 12 and 13 mounted for reciprocation therein and movable toward and away from one another during the operation 01" the engine.
' The pistons 11 and 12 of the two cylinders are connected by a piston rod'le which is terminally secured to the said pistons, and a cross head or yoke 15 has its intermediate portion secured to the intermediate portion of the rod 1 1 and projects through the opening 8 of the casting 7. Stems '16 are secured to the ends of the cross head "or yoke 15 and project toward the crank case 2, and the free ends of the stems 16 are provided with cross heads 17 working in longitudinal guides 18 provided upondiametrically opposite portions of the cylinder 1 adjacent that end of the cylinder remote from the crank case. Connecting rods, or pitmen 19 have their ends pivoted to the cross heads 17 and cranks 5. The pistons 11 and 12 being connected will be operated simultaneously in the same direction, and the pistons 9 and 13- are also connected to operate simultaneously in the same direction. 7 The piston 9 is provided with diametrically opposite outstanding arms 20;working in longitudinal slots 21 provided in op posite sides of the cylinder 1 adjacent the crank case 2, and longitudinal rods 22 each have one end secured to one of the arms 20. The rods 22 are located at opposite sides of the cylinders and project away from the crank case beyond the remote'end of the cylinder 6. The rods 22 are slidable through apertured guide ears 23 outstanding from that end of the cylinder 1 remote from the crank case, and through apertured guide ears 21 outstanding from the remote end of the cylinder 6. Those ends of the rods 22 remote from the crank case are connected The rods 22 t us connect the pistons 9 and i 13 whereby they move in the same direction. Each of the cylinders is provided with inlet and outlet ports 27 between its ends and between the pistons.
When the engine is employed as an internal combustion engine, suitable ignition means or spark plugs are provided for the cylinders between the pistons, and suitable" are also employed, which need valve gears not be illustrated'cr described in detail.
The pistons in each cylinder move toward and away from one another, so that when an explosionoccursin one cylinder, the pistons will be separated therein, .while the pistons of the other cylinder will be moved toward one another ior compressing the new charge. Assuming that the parts are in the position illustrated in Fig. l, when the explosion occurs in the cylinder 1, the pistons 9 and 11 will be separated, and the piston rod 10 will force daway from the cylinder 1, while the yoke 15 being forced away from the crank case by the piston 11 will cause the pit-men 19 to pull the cranks toward the cylinder 1. In this manner, the thrust created by the eX- plosion will be neutralized or balanced, to minimize the jarring or Vibration. Since the pistons 12 and 13 are moved in the same direction as the pistons 11 and 9, respectively, when the pistons 9 and 11 are separated, the pistons 12 and 13 will be moved toward one another for compressing the new charge within the cylinder 6. Then when the charge within the cylinder (3 is exploded, the pistons 12 and 13 will separate, while the pistons 9 and 11 will be forced toward one another for ejecting the burnt gases from the cylinder 1, and then when the pistons 9 and 11 separate, the new charge will be drawn into the cylinder 1, while the burnt charge will be ejected from the cylinder 6.
The engine may also utilize steam or other pressure fluid as a driving medium, and with the saine advantages as with the Copies. of this patent may be obtained for site directions,
the crank as may end remote from the other cylinder, a crank rotation withinjthe crank caseand having. a pair of cranks and shaft ournaled for an intermediate crank pro ecting in opp0- a pair of pistons working within each cylinder, a ineinberdisposed betweenqand secured to the adjacent ends of the cylinders and having an opening, a piston rod connecting the adjacent pistons of the two cylinders, yoke secured to said piston rod and working in said opening,
connecting ,rods connecting said yoke and said pair-of cranks, a connectingrod con.- necting the intermediate crankand that pi ton adjacent the crank -case,the first men tioned cylinder having longitudinal slots adjacent the crank case and the -last-n1entioned piston having outstanding arins working in said slots, longitudinal rods attachedto said arms, the cylinders having guides for the last mentioned rods, a yoke secured to the lastmentioned rods remote from the crank case, and a piston rod connecting the last mentioned yoke and that piston remote from the crank case.
within the scope of what is essential, without departing from:
In testimony that I claiin the foregoing.
as my own, I have hereto aiiixed my signae' ture in the presence of two witnesses.
