CYLINDER-DRIVE ENGINE.

Specification of Letters latent.

Application led January 5, 1914. Serial No. 810,521.

To all whom it may concern.'

Be it known that I, JAsrnR W. WOOD, a citizen of the United States, residing'at Needles, lin the county of San Bernardino and State of California, have invented a new and useful Cylinder-Drive Engine, of which the following is a specification.

This invention relates to internal combustion engines in which the engine transmits its power from the cylinder instead of from the pistons. I

An object of the invention is to provide an arrangement whereby to increase the efficiency of the internal combustion engine and to decrease the fuel consumption of the same. To these ends the engine is mounted to transmit its power in a direct line against the cranking shaft which `is made possible by mounting the cylinder of the engine to oscillate so as to transmit the power of the engine from the cylinder instead of from the pistons.

A further object of the invention is to provide a fuel feed into the firing and compression chambers of the cylinder; and this is done through a channel formed inside of the pistons of the engines and the cross head connected to the pistons about which the oscillating cylinder is adapted to-rock. With respect to this feature of the invention a carbureter is attached to the cross head or shaft to which the pistons are connected.

It is a still further object of the invention to provide an engine in which the engine member will operate with-the least resistance due to friction caused by side thrust or the like. This is accomplished by permitting the piston member and cylinder to operate relative to one another in a vdirect line, which particularly distinguishes it from a piston member connected toy an eccentric.

Another object of the invention is to provide an engine which is substantially yfree from liability lt0-knocks. To this'end adequate air cushions are provided in which the piston member operates.

Still another object of the invention is to provide a self-air-cooling engine.

Other objects of the invention are cheapness and simplicity of construction, minimum number of parts, minimum amount of machine work, ease and convenience of assembling and repairing and minimized liability of getting out of order.

:relation to each other and the rails.

The engine is provided with two cylinders fixed together and two pistons fixed together, the cyiinders working on the pistons and connected to a crank shaft.

rEhe particular feature of invention resides in the novel means of supplying fuel to the firing chambers of the cylinders. rlhis is effected through the pistons and the piston rod or rods connecting said piston,

the same being provided with a channel that' communicates at its ends alternately with by-pass passages in the cylinders; the arrangement being such that at the end of the compression stroke of one piston, fuel passes through such piston and the by-pass into the compression chamber for such piston while the by-pass into the combustion chamber for the other piston is closed by such other piston; and the exhaust port from the combustion chamber of the other piston, and a fuel passage into the combustion chamber of such other piston from the compression chamber therefor, are open; and vice versa, at the next stroke. The features, capabilities and advantages of the invention will become apparent from the subjoined detail description of one specific embodiment thereof.

The invention is illustrated in the accompanying drawings.

Figure 1 is a plan showing the cylinder drive engine mounted in position for use. Fig. 2 is an elevation in section on line `2-w2, Fig. 1. Fig. 2"* is an end elevation of the intermediate body -portion viewed from line .Qa- Q,Fig 2p Fig. S is an enlarged fragmental elevation in section on the staggered line w22-.r3 of Figs. 1 and 5.

Fig. 4t is an elevation of one cylinder in sec- I. tion on line art-mt, Fig. l, looking in the direction of the arrow. Fig. 5 is an elevation yon .line fc5-005 of Figs. 1 and 2, looking in the direction of the arrow.

In the embodiment shown a frame comprising two rails 1, 1, is provided with cross head bearing portions 2, 2, to support the cross head 3 on which the cylinderis slidably,rand by which it is pivotally, mounted to oscillate and rock. f'lhe rails 1, 1 are also provided with crank shaft bearing portions 4, i to support the crank shaft 5. IlLhe bearing portions 2, 2 and 4, L are in fixed rll`he cross head 3 is provided with a threaded transverse recess 6 to receive the inner threaded ends of piston rods 7, 7, which are Vscrewed into the opposite ends of the recess d aXls of the crank shaft.

` piston, the chambers being Yportion 21 of 15 as shown,

V11 forms with the end Each of the 'screw-threaded. Piston The piston rods 7 are connected with piston heads 22, 22 that operate in a double cylinder 8 to form firing chambers 9, 9, one

at each end of the cylinder 8. The cylinder is preferably composed of three portions; there being two end body portions 10, 10 and an intermediate body portion 11. The end body portions 10, 10 are each provided with suitable flanges 12, 12 to lit against corresponding flanges 13,13 of the ends of the intermediate body lportion 11 to form one continuous cylinder. The exterior end of one of the body portions 10 of the cylinder 8 is provided with an extension 14integral with said body portion to form a seat for a suitable securing portion to which the crank arm 15 of the crank shaft 5 may be pivoted,

as for instance (see Fig. 2) two bearing blocks 16, 16 provided with recesses to form a circular opening to receive the crank arm said blocks being held in place against the T-shaped extension 14 by means of the U-shaped binding rod 17 which is suitably bolted to the extension.

By means of its body wall the intermediate body portion 11 of the cylinder 8 forms Va longitudinal guide-way 18 running substantially through the body portion, the guide-way being adapted to receive the cross head 3 to permit the cylinder 8 to slide on said cross head when in operation. The intermediate body portion body portions 10, 10 19, 19, one for each separated from one another by partitions`20, 20, guide extensions 20 thereof, glands 41 and piston rods 7 working therein.

piston rods 7, 7 is provided with a diminished end portion 21 which forms4 a shoulder with the main body portion of its piston rod 7, the eXtreme end portion of the diminished portion 21 being heads 22, 22, each of whleh hasgan internal opening, having an enlarged portion 23 to lit upon the main bodyportionof thepiston rod 7 and a dimmlshed portion 24 to yfit the diminished the piston rod 7, are adapted be secured onto the ends of the piston rods 7, 7, being limited in their inward movement by the shoulders formed by the diminished body portions 21, 21 and diminishedy openings 24, 24. have recesses 25, 25, surrounding their diminished openings 24, 24, so that when the piston heads are mounted onto the piston rods, nuts 26, 26, which secure the piston entire middle of said compression chambers Athe bearing portion f ber 19. As firing The pistonV heads Y 22 heads from outward movement, being screwed onto the screw-threaded ends of the diminished body portions 21, 21, will be located in their recesses 25, 25. Cotter pins 27, 27 are provided to secure the nuts 26, 26 from movement.

The vaporized or other gaseous fuel is conveyed to the compression and liring chambers from the fuel source through the cross head 3, piston rods 7 7 and heads 22, 22. In Figs. 1 and 5 there is shown suitably mounted on one of the rails 1 adjacent to 2, a housing 2S to which a carbureter 29 is connected. The cross head 3 is provided with an internal channel or chamber 30, and the piston rods are provided with internal channels 31, 31 and with a port 46 to form a communication between the carbureter 29 to supply fuel to the internal channels 31, 31, formed in the piston rods adjacent compression chamber 19 a passage 33, communicating with channel 31, is provided in each piston head, which effects intermittent communication to its adjacent chamber 19 by means of a bent or U-shaped channel having an inlet 34 and an outlet spaced apart longitudinally of the cylinder. The respective body portions l0, 10 may bulge out to accommodate the U-shaped channels as shown in Figs. 1, 2 and 3. This intermittent communication is effected for eitherpiston when its piston head is in a position nearest to the outer end of the body portion 10 of the cylinder in which it operates. In this position, as shown by the right hand piston head in Fig. 2, the passage 33 registers with the inlet 34, and the outlet 35 opens into the compression chamtakes place in the firing chamber 9 the adjacent end portion 10 of the cylinder is driven away from its piston head whereby as shown in the left hand side of Fig. 2 the feeding communication to its compression chamber 19 is eut olf.

Similar to the compression chambers, when feeding fuel to the firing chambers, one is first fed and then the other, the feeding to the firing chamber 9 of either piston head taking place when the feeding to the compression chamber of such piston head is cut oli', and vice versa. As shown in Fig. 3, when firing has taken place at one end of the cylinder, and that end of the cylinder is in a position away from the piston head communication is made between the liring chamber 9 and the compression chamber 19 by the L-shaped passage having an inlet 37 and an'outlet 38. The -outer wall 39 of the L-shaped passage bulges outwardly from the main contour of its end body portion 10. As the fuel rushes into the firing chamber through the outlet 3S it will strike a deflector 40 which is provided to direct such fuel into the chamber 9. A deflector 40 is provided on the face of each piston head 22.

To prevent leakage from the compression chambers 19, 19 through the operation of the piston rods, suitable packing glands 41, 41 are provided which are located, one at each end of the guide Way 18.

Spark plugs 42, 42 are provided projecting into the firing chambers 9, 9, in the usual manner, .the spark plugs having a wire connection with contact members 43, 48 provided on the outside of the end body portions 10, 10. 0n the rails 1, 1, preferably on one of them, as shown in the present instance, contact members 44, 44 are provided in position to alternately Contact with the contact members 43, 43, respectively, on the outside of the end body portions. 'llhe arrangement is such that when the cylinder 8 is oscillated in one direction, one set of contact members Will register to fire one end of the cylinder, and when oscillated in the other direction, the other set of contact members Will register to fire the other end of the cylinder. The contact members 44, 44 are adjustably mounted to facilitate adjusting for various causes.

Openings 45, 45, are suitably located, one for each firing chamber 9, to pass off the exhaust.

It is obvious that various changes and modifications may be made in the details of construction Without departing from the general scope of the invention.
