INTERNAL-COMBUSTION MOTOR.
Application filed June 11, 1925.
This invention relates to mot and has particular reference to certain improvements in the general construction and arrangement of the elements of an internal combustion motor.
In the common accepted forms of standard internal combustion motors, use is made of a cylinder with a reciprocating piston therein, a crank shaft and a connecting rod for transmitting rotary motion to the crank shaft, together with intake and exhaust valves controlled by a cam shaft operated from the crank shaft.
The present invention contemplates the simplification of the construction of a motor of the character set forth by the reduction to a minimum of the number of working parts by the elimination of crank shafts, connecting rods, pocket valves, and valveoperating` means.
The present invention aims for some of its principal objects to eliminate all reciprocating parts except the pistons; to provide pistons which are detached from the other elements of the motor except for a driving connection with the drive shaft; to )rovide a motor from which side thrust, wiping, or vibration is practically eliminat ed; to provide a motor in which acceleration is theoretically perfect; to provide fuel conduits from which angles which tend to impede the passage of the fuel, are absent, thereby permitting a straight flow; to provide a fluid-cooled motor in which the use of a pump is dispensed with and the flow of the fiuid is effected by centrifugal force; and to provide a motor in which the adjustment for compensating for wear may be readily had and this while the motor is running. j
The invention furthermore comprehends the production of an internal combustion motor in which the cost, weight, size and friction are greatly reduced, and in which the general etiiciency is greatly increased.
lVit-h the above recited and other objects in view, reference is had to the following specification and drawings in which there is exhibited one example or embodiment of the invention which is in no way intended as a limitation upon the scope of the appended claims as it is to be clearly understood that f'ariations and modifications which properly fall within the scope of said claims may be resorted to when found expedient.
Serial No. 36,497.
1n the drawings- Figure 1 is a longitudinal sectional View through a. motorl constructed in accordance with the invention;
F ig. 2 is a plan view thereof,
Fig. 3 is a cross sectional View on an enlarged scale;
Fig. 4C is a fragmentary sectional plan view of the piston, illustrating the driving connection between the same and the drive shaft;
Fig. 5 is a transverse sectional view illustrating the valve, and
Fig. 6 is a perspective view of one of the valves.
Referring to the drawings, the motor illustrated is of the two-cylinder type, it, however, being understood that the same may be made up of one or more cylinders without in any way departing from the spirit or scope of the invention. In the drawings, 10 and 1l designate the sections of each cylinder, which are provided with flanged open inner ends 12 adapted to be bolted or otherwise secured together by bolts or fastening elements 13. Each cylinder' section is provided with an outer closed cylinder head lat having therein circumferentially spaced substantially sector-shaped intake and exhaust ports 15 and 16. A drive shaft 17 extends axially through the cylinder or through the several cylinders where more than one are employed, the same having a bearing` in the cylinder' heads. A piston having piston heads 19 and 2O on its opposite ends, is mounted for beth reciprocating and turning movements in each cylinder, and defines between said piston heads, the opposite ends of the cylinder and the cylinder heads, combustion chambers 21 and Q2. The piston of each cylinder is splined to the drive shaft through the medium of a transverse key 23, which passes through a transverse opening in the drive shaft, with the outer terminals slidably engaging slots 2l in the connecting webs 25 of the piston heads 19 and The pistons 18, which are preferably of cylindrical construction, are provided with a circumferential continuous, sinuous or helical groove 2G having inwardly beveled opposite walls 27. At diametrically opposite points, the cylinders at the juncture of their sections 10 and 11 have mounted in the guideways 2S, a rotatably adjustable carrier 29. A pair of tapered abutment rollers 3() are mounted on the carrier 29 for engaging within the sinuous or helical groove 26, whereby each reciprocation of the piston imparts thereto a rotary motion for turning or rotating the drive shaft with the piston. The carrier members 29 are adjusted by means of a jack screw 3l, which threadingly engages a cover plate 32 for the guideways 28, and a binding nut 33 ic employed for maintaining` each carrier in its adjusted position. rlhe intake and exhaust ports l5 and 16 are connect-ed and communicate with the intake and exhaust manifolds or conduits 84 and 35.
`nately reciprocate the piston in opposite directions.
The spacing of the intake and exhaust ports is such that after the port 3T of the valve has established communication between the intake manifold and the combustion chamber, the piston moving in.` a direction away from the cylinder head, will have drawn inA a charge of fuel; the disk valve then. cuts olf communication so that the next stroke of the piston toward the cylinder head will compress the charge after which the ignition of the charge effects the power stroke of the piston in a direction away from the cylinder head. The next stroke of the piston toward the cylinder head causes the burnt gases to exhaust throu 'h the exhaust n'ianilfold, due to the fact tl t the port 37 of the disk valve registers with the .exhaust port' 15,4 after which the int: of the charge of fuel follows. is the charge being 1g;- nited in. one end of the cylinde1 and the piston bei-ng moved in a direc i on a way from the cylinder head, the opposite piston head will be moved toward the cylindre; head to exhaust the previously spent ch Likewise the next stroke inthe opposieV direction will* be drawing in: a fresh charge while the previously ignitedl charge is exhausted in the opposite end, and., subsequently, on the next stroke the intake of the charge will be compressed while a fresh charge will be drawn inthe opposite end and compressed by the ignition and explosion of thel charge at the opposite end. lt is preferable to employ at least two pairs of cylinders in order that each stroke of the piston will be partially effected by the explosion.
ln order to provide means for cooling and lubricatiine` the working; parts of the mot-or, an oil radiator 40 is provided, which is con- Lerares discharging` the oil from the oil radiator Ll0 into theV interior of the: piston for' cooling,-
the same, and, at the saine time,` applying` lubricant to the engaging faces of the abutment rollers 30 and the groove 26, while supplying the necessary lubricant to the outer walls of the piston and inner walls of.
the cylinder. rlv'he excess oil', due to the centrifugalY force, is thrown' outwardly through the groove or slot 2b', andl through an opening d? covered by an oil-return pipe d8, which lea-ds back to the oil radiator after passing` through a strainer screen 49. desired, as illustrated, an air inlet nozzle or hood may be provided and disposed in a' direction to cause a circulation of air within the piston.
l.. ln an internal combustion motor, a cylinder, a piston mounted therein for reciprocation, interengaging means on the cylinder an d piston for effecting rotary motion therebetween during` the reciprocations ofthe piston, and. a drive shaft extending,l axially through the cylinder andl piston, having` splined connection with the piston, the said cylinder having cylindrical heads at its opposite ends, each provided with circumferentially spaced intake and exhaust ports and disk valves keyed tothe drive shaft, disposed within the cylinder heads, eachk disk valve having a single port therein adapted to register with the intake ports during the inward movement of the pistons, to be disposed in a nonfregistering position` withthe cylinder head ports during the succeeding outward and inward: strokes and adapted to register with the exhaust port during the succeeding` outward stroke.
