Application filed March 10, 1916. Serial No. 83,283.
To all whom it may concern:
Be it known that I, DANIEL APPEL, a citizen of the United States, residing at Cleveland Heights villa e, in the county of Cuyahoga and State of ()hio, have invented a certain new and useful Improvement in Internal-Combustion Engines, of which the following is a full, clear, and exact description, reference being bad to the accompanyingldrawings.
y invention relates to lmprovements in internal combustion engines of the two-cycle type, and the object of my invention is to eliminate .the use of the crank case as a pump chamber, to avoid leakage of the new charge through the crank shaft journals, and my improvement consists in employing the lower end of the cylinder and iston as a supply pump for the new charge fiy dividin the lower part of the cylinder into two $11 stantially semi-cylindrical pump chambers with a vertically extending slot between the chambers to provide operative movement of the-connecting rod between the piston and crank shaft.
My improved engine, which is preferably of the vertical three-port type, is hereinafter more fully described in connection with the accompanyin drawings which form a part of the speci cation. The same letters of reference indicate corresponding parts in the several views.
In the drawings, Figure l is a vertical central section of an engine embodying my invention, this section being in the plane in which the connecting rod operates; Fig. 2 is a vertical central section in a plane at right angles to Fig. 1, looking toward the left hand side of that figure, and showing the piston in its uppermost position and partially in outside elevation. Fig. 3 1s a cross section through the exhaust ports and upper transfer ports, as indicated by the line 3-3 on Fig. 1. Fig. 4 is a cross section through the intake ports and lower transfer ports, as indicated by the line 4-4 on Fig. 1. The remaining figures are details, on a larger scale, of the piston and the artition housing for the connecting rod; Figs. 5 and 6 are central vertical sections at right angles to each other through the piston; Fig. 7 is a transverse cross section, as indicated by the line 7-7 on Fig. 6; Fig. 8 is a transversevertical section of the housing; Fig. 9 is an inside elevation at right angles to Fig. 8, of one half of the housing, and Fig. 10 is a plan of the housing.
Referrin first to Figs. 1 and 2, 11 indicates the cylinder, 12 the piston, 13 the crank shaft, 14 the connecting rod, pivoted to the piston and the crank, and 15 a stationary tubular housing with a circular base, fitting into the bottom end of the cylinder. As shown the lower end of the engine cylinder is provided with an external flange 21 secured to an annular rim 22 of the crank case 20 by the usual means, while the housing 15 15 so secured to an inwardly projecting flange 48 of the crankcase as to permit it to aline with the piston. The crank shaft may be mounted in a two-part casing 20, as shown.
The piston has on its upper surface the usual deflector 31 and near the-top the packing rings 32. Below these is a transverse bearing 33 for the wrist pin 34, and below the wrist in the piston continues for a length'sligl ftly more than the stroke of the piston. The lower portion of the piston is ivided by a slot 35, diametrically across and at right angles to the wrist pin, and parallel fiat walls 36, form the sides of this slot and unite with .the circular walls of the piston adjacent to the walls of the cylinder, to form substantially semi-cylindrical downwardly projecting hollow plunger-s closed at their upper ends by the wall 37,'but communicating with the cylinder space below.
The stationary central partition for inclosing the connecting rod is of the form shown in Figs. 8, 9 and 10, and consists of a circular base 40 with an upwardly extending tubular partition 41, and rising therefrom for a distance slightly greater than the stroke of the piston, the partition and base being composed of two parts and joined vertically adjacent to their edges by inwardly projecting ribs 42, and secured together near the upper ends by screws 45. The housing thus provides a tubular partition which extends diametrically across the cylinder and provides a slot 43 in which the connecting rod can freely operate. It is to be understood that the inner' faces of the piston slot 35 and the outer faces 41 of the central partition must be in sliding contact with each other, similar to the circular face of the piston with the walls of the cylinder. It is also to be understood that any wear between the flat walls of the partition and piston may be taken up by separating the members of the two-part partitions. I
Referring now to the several ports in the cylinder and piston of the engine; these are preferably arran ed in palrs near the outside of the partltion walls of the tubular housing and the flat walls of the piston. In Fig. 2 at 50, 50, are shown two Intake ports through the lower portion of the cylinder leading from an intake passage 51. 52, 52 indicate lower transfer ports opposite the intake ports and leading to a transfer channel 53. This channel is shown on the outside of the cylinder wall, covered by a suitable plate 54. At its upper end the transfer channel communicates with two ports 55 leading into the upper end of the cylinder, and opposite these ports are the exhaust ports 56, 56, 'communicatlng wlth the exhaust port 57. In the-piston walls,
near the upper end of the semi-cylindrical. compression chambers, are two ports 58 adapted to register with the transfer ports 52 when the piston is at the lower end of its stroke, as shown in Fig. 1,
It will be seen from-Fig. 2 that when the piston is at the upper end of its stroke the intake ports 50 are entirely uncovered, and
as the piston moves downward, ports 50, 50
' will-be closed, than as the plston nears the lower portion of. its stroke, first the exhaust ports are uncovered, and then, wh1le the uncovering of these ports continues, the piston ports 58 are coming into registration with the lower transfer ports 52, and immediately thereafter the piston uncovers the upper transfer ports 55. The registration of the ports 58, with the ports 52, is slightly in advance of the uncovering of the ports 55. In the lowermost position of the pis: ton, shown in Fig. 1, both transfer ports and the exhaust ports are fully open.
Assuming that on the up stroke of the piston a partial vacuum is created in the semi-cylindrical pump chambers provided between the lower endof the cylinder and piston, and when the piston uncovers the intake ports 50, combustible mixture is drawn in from the carbureter, and as the piston descends, this combustible mixture is compressed in the pump chambers, and when the ports 58 in the piston reach the lower transfer ports 52 the combustible mixture flows into the transfer passage channel 53- and immediately afterthe piston uncovers the upper transfer ports 55, and the new charge is forced through these ports into the combustion end of the cylinder. The new charge, on entering the cylinder, is diverted-upwardly by the deflector 31, and passes the spark plug 61, and while turning nausea the exhaust port is being fully uncovered.
My improved engine is shown herewith as a three-port single air-cooled unit, with cooling ribs 60, but it will be. understood that my improvements apply equally well to other typesof two-cycle engines, and other forms of cooling may be employed, and that the cylinder may be arranged on the crank case in any desirable manner, without departing from the spirit of my inventlon.
