To ell whom it may concern I Be it mown thatwe, HARRY H. ABBOTT and 7 Hanson L. DEAN, citizens of. the United Eitates of America, residin at Coldwater, in the ceunty of Branchv and tate of Michigan; have i vented certain new and useful .Im-
\ provernents in Explosive-Engines. of which the following is a specification, reference be ng had therein to the accompanying draw l In the internal combustion engine the velocity with which the charge is injected into the compression end of the cylinder does notvary as the speed increases or decreases,- but is necessarily constant.
This invention relates to a two-cycle internal combustion engine wherein provision" is made to vary-the time of the intake of the charge in proportion-to the speed of the engine and wherein also the amount' 'o'f the charge can be varied at will.)
pointed out in the appended claims.
In the drawings, Figure l is a view in sectional elevation through one pair of cylinders and the adjacent parts of a motor embodying features of the invention; Fig. 2 is a View in section taken through the cylinders and a supply cylinder on orabout line of Fig. l and with-the partspro jected in the same plane; Fig. 3 .is a-view 111 detail ofthe supply cylinder operatingshaft; Fig. 4 is 'a View in longitudinal sec. tion through a supply cylinder taken on line g g of Fig. 1; Fig. 5 is a view similar to Fig. 2 of a modified form of the device;
and Fig. 6 is a view in longitudinal section of the supply cylinder ofthe' modified form. As herein indicated the motor is shown a four-cylinder type in which cylinders other.
are disposed in pairs at 90 degrees to each A crank shaft 1 has a pair of op ositely disposed crank pins 2, in the same plane and consequently 180 degrees apart or diametrically opposite. A pair of opposite cylinders 3 and 4 are" disposed at 90 degrees to each other. ,Eachhavc their usual arrangement of a two-cycle.

A spur pinion 35 is journa'led on the pin 32 in mesh with the internal gear 33. The pitch diameter of the pinion 35 is one, half the pitch diameter of the. internal gear 33, and a pin 36 is mounted on an arm 37 carline thereof. .The pin is journaled in a earr inflsr rist n $9. a

the other cylinders in a line parallel to the crank shaft 1. A plair-of oppositely disposed .15 at one end 'of the cyl of the cylinders 9 and 10. As shown in. Flg.

A piston 27 playing in the cyIinder-13-is driven froin the mainsha ft l through anyigo 31 and wrist p1n'32. The latter revolves ing at the end of a piston rod 38 connected cylinder piston the pin rotates the pin 36 travels back and forth along the diametrical line indicated at Z that is an extension substantially of the axis of the supply cylinder 13. -vents.any sidemovenient of the piston and gives the required stroke thereto.
In the operation of the form of motor just described, if the parts are in the position shown inF-ig. 1, the movement of the piston 27 of the supply cylinder half-way toward the ports 14 and 15 thereof forces one-half of the contents of the supply cylinder through the inlet port 11 and into the cylinder 4, the position of the pistons in relation to the inlet ports 11 of the main cylinders 3 and 4 being so disposed as to permil: this. \Vhen this one-half stroke has been completed the piston of the cylinder 4 has closed its inlet port 11 and at the same time the piston of the companion cylinder 3 commences to open its inlet port 11 so that the completion of the stroke of the supply 27 forces the remaining half of the supply-cylinder contents into the cyl inder 3. At the same on the other side of the supply cylinder piston and consequent tendency to cause a vacuum, has drawn a full charge into the supplycylinder 13 through the carbureter valves and the inlet port 23 at that end of the supply cylinder. The reverse stroke of the supply cylinder piston for half its length forces one-half of the contents of the supply cylinder through the inlet port of the cylinder 9 which is uncovered during this time by the piston of the latter, and during the remainder of the stroke, is filling the cylinder 10 through its inlet port.
To increase the effectiveness of the intake of the cylinder the piston heads have bafiles disposed as indicated at directing the incoming charge against the head of the cylinder and allowing theeXhaust charges to be scavenged or driven ahe d and cut through the exhaust ports indicated at 12.
If it desired to diminish the amount of carbureted air that is indrawn, the closure '25 controlling the bypass indicated at 26 is opened to a greater or less extent therebv allowing the charge displaced by the supply cylinder piston to be moved from one end' of the supply cylinder to the other end with out wholly entering the main.
In the modification shown in Figs. 5 and 6, asupply-cylinder 39 is provided of the same capacity as the main cylinders. Its piston 4:0 is driven from a transverse shaft 41 turning at twice the speed of thomain shaft 1 as through the medium of suitably proportioned bevel gears 4:2. The stem 43 of the piston may be driven by the same device as shown in Figs. 2 and 3, or may have other suitable connections such as a slotted yoke 44 engaged by a pin 45 on a wrist plate 46. The inletvalves may "be arranged This pretime the displacement as indicated at 47 and by-passes shown at 48 j may connect the main cylinder inlet ports 49. i The disposition of the cylinders minimizes the number of crank shaft connections and bearings While rigidity is obtained by the arrangement of the cylinders, in which the supply cylinder acts as a strut connect ing the diverging bodies of the main cylinders.
Obviously, changes in the details of construction may be made without departing from the spirit of the invention and We do not care to limit ourselves to any particular form or arrangement of parts.
