GAS-ENGINE.
Specification of Letters Patent.
lPatented May 3, 1921.
' Application sied July 3, 1919. serial No. 308,377.
To all whom-t may concern:
Beit known that I, WILLIAM E. DEisoH, a citizen of the United States, residing at Portland, inthe county of Multnomah and State of Oregon, have invented n ew and useful Improvements in Gas-Engines, of which the following is a specication.
This invention relates to gas engines, particularly to those of the multi-cylinder tw o cycletype, and has for its object the `provision of an improved engine in which each cylinder is formed in sections of, different diameters and in which each cylinder has working therein a differential piston having one section operating in one section'of the cylinder constituting the explosion chamber and another section operating in the .other section of the cylinder and constituting a charge forming device for compressing a charge' and delivering it to the explosion seotion of the next adjacent cylinder, air automatically opened and closed passage. being provided for establishing communication between adjacentcylinders, action in the adjacent cylinders being mutual or reciprocal.
An important object is the provision o f an engine of this character which is provided a novel port and passage arrangement for effecting the transfer of a charge from the compressing and charge forming section of one cylinder to the explosion section of the next adjacent cylinder, the invention being adaptable for use in connection with any two cycle motor having an even number of cylinders set side by side in parallel'relation or arranged as in a V-type motor or also arranged in opposed relation, andthe structure may also be employed on engines using any of the well known types -of fuel. An additional object is the provision of an engine of this character which lwill be comparatively simple in construction and operation, which will be efficient and durable in use, and a general improvement in the art.
With the above andtother objects and advantages in view, the invention consists in the details of construction to `be hereinafter more fully described and claimed, and illustrated in the accompanying drawing, in which V Figure 1 isa longitudinal sectional view of an engine constructed in accordance with m invention, and c lig. 2 is a lon itudinal sectional viewv on the line 2-2 of ig. 1. Y
ing, I have shown an engine Referring more particularly to the drawcomprising cylinders designated broadly byl the numerals 10 and 11 arranged side by side in parallel relation, the engine being of the two cycle type. The cylinder 10 comprisessections 12 and 13 of different diameters,l the former being the smaller and constituting the explos1on section or chamber and the latter constituting a compressing or charge' formand not being essential to a clear understanding thereof. The cylinder 10 is also provided with a packing ring 19 at the lower end ofthe section 12 and this packing ring firmly engages the section 14 of the piston for making a fluid-tight joint. The cylinders are alsoprovided at their upper ends with the usual spark plug openings 20.
The cylinder 11 is identical in construction with the cylinder 10 and comprises the sections 21 and 22w1'thin which are movable the sections 23 and 24 of the piston provided -with the usual connecting rod 18.
.Formed in the `cylinders l0 and 11 are intake ports 25 and 26, respectively, and exhaust ports 27 and 28,respecti'vely, and
-these various ports are connected with the proper` manifolds, as shown, in the ordinary manner.d Formed in the walls of the sections 14 and 23 of the pistons are passages 29 and 30, respectively, which at certain times are adapted to register with the intake ports 25 and 26, respectively. Formed in the walls of the piston sections 15 and 24, are passages 31 and.32, respectively, which are at certain times adapted to register with openings or ports 33 and 34 formed in 'the sections 12 and 21'ofthe cylinders, Arespectively. The ports 33 and 34 communicate with a 4passage 35 lformed in a member 36 disposed between the cylinders 10 and 1-1.
When either of the passages 31 or 32 is in registration or communication with the opening 33 or 34 as' the case may be, communication will` be established between the cylinder section 13 and cylinder section 21 or between the cylinder section 12 and cylinder section 24, the former mentioned position being shown in Fig. 1. i
The operation of the engine is as follows Referring to the, drawing it will be seen ithat the piston in the cylinder 10 is at the top of its stroke and that the piston in c linder11 is at `the-bottom of its stroke.
hen the piston in cylinder 10 starts on its down stroke a partial vacuum will be caused in the cylinder section 13 until the piston approaches the bottom of its stroke, whereupon the port 29 in the piston section 14;'
. will register with the intake port 25, where-v the piston starts on its upstroke, the ports and 27 will be covered and the mixture within the cylinder section 13 will be compressed until the upper end of the passage 31 registers with the opening33 in the cylinder wall 'whereupon this compressed mix- 15 port 2G at the lower limit of the stroke, fresh ture will pass through the passage 35 in the member 36 and through the opening 34 into the cylinder section 21 .of the cylinder 11. The piston in the cylinder 10 upon reaching the top of its upstrokeisready to repeat its cycle of opera-tions. Nhen the Vpiston in cylinder 10 reaches vthe top of its stroke the piston in cylinder'll is at the bottom of its stroke and the charge whichwas previously compressed within the cylinder section 13 is then in the cylinder section 21. As the piston in cylinder 11v then moves upwardly the mixture within the section .21 will then be compressed. As the piston in `cylindervll subsequently starts on its down stroke and the port 30 registers with the mixture will bc supplied to the cylinder section 22 in exactly the same manner as it was supplied to the cylinder section 13 and 'the operation of the piston in cylinder 11 is identically the same as that of the piston in cylinder 10. It will be noted that thepistons and ports as well as the other parts, are so arranged that the action in each cylinder will bey reciprocal to that in the other cylinder. Another feature of the invention is that the top walls of the piston sections 14 and 23 are so formed that when a partially compressed charge is forced from either cylinder into the other, `the charge will, upon encountering the curved top'wall of the piston, b e deflected upwardly in the proper direction. j
. From the foregoing description and a study of the drawings it will be apparen that I have thus provided a simply constructed engine of the two cycle type which is adapted'to have its cylinders arranged,
in various wgaysand which is provided with novel means whereby each cylinder partially compressesa charge and forces it into the explosion chamber of the next adjacent cylinder, the arrangement being such that the cylinders are reciprocal.
While I have shown and described 'the preferred embodiment of my invention, it is of course to b e understood that I reserve the rightto make such changes in the form,
each cylinder formed in sections conform ing to said cylinder sections and slidable therein, each cylinder being provided in the smaller section thereof with an eXhaust'port and being further provided intermediate the ends ofthe smaller section with an inlet port, `the smal-ler section 'of each cylinder having further formed therein a port opposite the exhaust port, a passage member c0nnecting said cylinders and establishing communication between said last named ports, the upper portion of the smaller section of each piston having formed in one side thereof a longitudinally elongated depressed portionforming a passage adapted to register with the inlet port and to establish coin- I'nunication therebetween and the. larger section of the cylinder, said inlet port being arranged approximately at right angles to the exhaust port and said last named port, and the lower portion of the smaller section of each piston having formed in one side thereof a Adepressed portion forming a passageI adapted to ,establish communication between the larger section of the cylinder and the smaller section of the other cylinder throughsaid last named ports and said passage mcmber.
