Description

20 is another duct 22. These ducts 20 and 22 are connected at their inner ends and thus provide an opening in the wall of the cylinder and by this means a constant supply of oil to the bore l2 and to the face of the valve 14 is insured. An oil cup 23 is connected to the oil duct 22 and constitutes the oil supply for the valve 14, bore 12, piston 6 and wrist pin 5.l

.ln order to lubricate the surface of the piston 6, the valve 14 is apertured with a plurality of oil openings 24 near the bottom.

hese openings register at ltimes with the oil groove 18'and when in such register, oil flows through the openings 24 into the bore of the valve 14 and is in turn taken up by. The oil will the reciprocating piston 6. gradually work upwardly and cover the entire surfaces of the frictional parts. Some of the oil on the surface of the bore 14 will be collected by the edges vof the bore 7 in the wrist pin 5 as the piston travels up and down and the oil t-hus collected will gradually fill the bore 7 and furnish lubricant to the connecting rod bearinghead as before explained.

Formed on the bottom of the rotary sleeve valve is a gear 25 which meshes with a worm 26 fixed on a longitudinally yextended shaft 27 whichshaft is mounted in suitable bear ings in the casing as shown in Fig. 4. The shaft 27 has a sprocket wheel 28 on its end and a similar sprocket 29 is mounted o n the crank shaft 2. A chain 30 travels over both of these sprockets and serves to drive the shaft 27 and rotate the valve 14.

Cast integrally with the valve 14 and adjacent the gear 25, is an annular flange 31.

The flange 31 fits closely in the opening in` the top of the casing 1 and by its means the valve is held in place. The upper side of flange 31 lcontacts with the cylinder flange 9 andy-1s engaged by a two-part ring 32 at the under` side as shown in Fig. 1.i The ring 32 is made in two parts so that it can be fitted around the body of the valve 14 between the flange 31 and the base of the gear 25 and a part of eaqh of the abutting edges of the ringis cut away at one side.

ing 1 is out away adjacent the This is'done to permit access' of the pinion 26 to the gear 25 as shown. Suitable screw holes are rovided in the ring 32 so that Yit may be.v` astenedl -vintc place `and form a thrust bearing base forI the-valve 14 which` rests thereon throughV the-flange 31. The ,holdingring 32 is received in groovesp38, see Fig. 2. A portion of the top of the cas- -Y and sprocket 28 so as to accommo ate these parts when the device is assembled. The' opening referred to, is closed 'by a cover plate 33 as sho-wn in Fig. 1.

By reference to Fig. 2, it will be seen that the cylinder 10 is provided with intake and exhaust ` ports 34 and 35 which are arranged plosion chamber.

inion 26 port 34 until at the time-that thepisto'n' establish communication between the explo'- sion chamber of the engine and the' intake l..

and exhaust manifolds 36 and 37 at certain times. Such communication is out off by the wall of the interposed valve 14.u The valve 14 is provided with a single port 39 which is adapted to register attimes Witlv the ports 34 and 35 thus establishing com- Inunication` between these portsand the ex- This port 39 therefore performs the dual functions of inlet and exhaust port for the explosion chamber and is brought into registration with the ports 34 and 35 as stated above, at the propertime when the piston 6 is traveling its intake and exhaust strokes7 by the rotation of the valve 14. By reason of the rotation of the valve 14 in a horizontal plane while the) piston 6 travels vertically, the contacting surfaccsof the piston 6 and bore of'valve 14, are constantly changed. Therefore, should foreign matter become lodged between the piston and the valve, there will be no danger of the wearing of vertical grooves in the surface of the bore of the valve causing a means for gas leakage. A spark plug 40 is screwed into an opening in the head of the cylinder 10 and serves to ign-ite the explosive mixture when compressed by the piston.

Operation: From the foregoing descrip* tion of. the various parts ofthe device the operation thereby may be ureadily under-` stood. Attention is now directed to Figs. l, 2, 5, 6, 7 and 8 which illustrate the positions of the port'39 of the rotary sleeve valve 14 during one complete -cycle of operation of the engine or during two revolutions of the crank shaft. l The diagrammatical views Figs. 5 to 8 are composite views, the upper portion being a cross sectlon through the ports 34 and 35 and valve 14', v4

while the lower portion of each view is a vertical section the two parts of the views being joined by a dot and dash line and in-l tended to be read together. In Fig. lathe piston 6 is at the top of its stroke and is Just about to descend, the crank 3 turning in a clock-wisedirection. When the piston 115 is in thisposition the port y39 in the valve 14 is just 'midway of the exhaust shown in Fig. 2, but as the piston descends the valve 14.is turned so as to gradually register the valve port 39 with thetiltake port 34-so as to admit thenewcharge.` which is being reaches the bottom loit'sl 'stroke asfslrwmf uis-in, n
