Application led May 17, 1912, Serial No. 697,852. Renewed May 1, 1915. Serial No. 25,298,

To all 'whom it may concern.'

Be it known that I, HUGO C. WELL, a subject of the German Emperor, and a resident of the city of New York, borough of the Bronx, in the county and State of New York, have invented a new and Improved Internal-Combustion Engine, of which the following is a full, clear, andl exact description.

My invention relates to engines, and itv has for its object to provide one of the internal combustion type which has a piston with a rotatable valve member with a port which is adapted to receive the combustible mixturev through a port in the side of the cylinder, the rotatable valve member also having ports which are adapted to register with ports in the piston to permit of a quick circulation of air in the cylinder to cool the cylinder and clear it of all products of combustion.

Other objects of the invention are to direct air to one of the ports in the piston, to lead the air. from the other port in the piston and out of the cylinder, and to rotatethe valve member in the piston.

Still other objects of the invention will appear in the following complete specifica tion, in which the preferred form of the invention is disclosed.

Certain features of this invention are disclosed in applicants co-pending application having Serial No. 778,075.

In the ,drawings similar characters of reference indicate corresponding parts in all the views, in which- Figure l is a sectional elevation of my im'- p proved engine;

of Fig. l1; and

Fig. 2- is a sectional view on the line 2--2 of Fig. 1;

Fig. l3 is a-sectional view on the line 3-'3 Fig. 4 is an enlarged fragmentary vsectionalview showing haw the ratchet teeth portant that the cylinder be thoroughly cooled and cleansed of all products 'of comi' bustion before the admission of anew chargeof'the .combustible mixturev but with the "r'rapid'movement of the piston,` there is dii= i feulty in clearing theycylinder when'o'nly'an y exhaust valve is provided; *My invention includes means. for forcingf-alr'under pressure througihfthe cylinder after the explosion, and in 4thepreferred 'embodiment "of the invention, shown in the drawings, this air is led through a port in the piston and out of another port, the ports being commanded by a valve member mounted for `rotating on the piston, the valve member also being pro.-

member 9, this casing member 9 having a port 10, with which the pipe 11 communicates. The cylinder 5 isfprovided with an- `elbow 12 at the port 7, a tube or conduit member 13 being secured to this elbow for communicating with the ports 7. "The tube ort in the cylinder,

' at the outer side of the cylinder 5 by a casingor conduit member 13 is disposed longitudinally of the cylinder 5. In the cylinder 5' there is disposed a piston 14, having ports 15 and 16, which are commanded by the valve member 17, this valve member 17 having ports 18, with which the ports 15 and 16 are adapt'- ed to communicate. Integral with the piston 14, 'there are two conduit members .19 and 20, the conduit member 19 `communicating with the port 16, and the conduit member 20 communicating with the port 15. The lower terminal 21 of the conduit member 19 is dis` posed outwardly, affording communication between the scavenger ports 8 andthe conduit 19. The tube or conduit 1 3.4 is disposedy in and telescopes withthe'c'onduit 20. The

valvemember 17,v which is disposed on the 4piston-"14, is connected With a ratchet disk 22 by a stud 23, which is'dispgosed through an orifice 24 in the piston14. v 'This ratchet disk 'Y 22 is disposed at the underside of the piston 14, and'is provided for-.rotating the valve member 17.. The valve member 17 has a pe.-

ripheral-rim.25,.having.fports 26, which are adapted'- toregister with:the-portl 6 inythe 1 gaging the Aratchet disk 22 at one side pf its- -cylinder`, for-affording communication bel sleeve, 29 has athread' I center. There aslo't 32 in the ,sleeve 29, in

which is disposed a guide screw or pin 33, which is secured to the ratchet tooth 31, and limits the movement of the said ratchet tooth. The ratchet tooth 31 is held yieldingly extended by a spring 34, which is disposed' in the sleeve 29, the face of the upier terminal 35 of the ratchet tooth 31 being isposed obliquely relatively to the sides of the `rthe opposite direction, the sprin ratchet tooth', so that While it Avvill have a positive movement with the ratchet disk to rotate the valve member 17 in one direction, it will move freely over the ratchet disk in 34 assistingl in this return movement. pawl 22* may be provided to prevent the ratchet disk conduit 20, the conduit 13 and the port 7,

the pipe 11 being in communication with a supply of air under pressure so that as soon as one of the ports 18 in the valve member 17 registers with the port 16, one of the ports 18 in the valve member 17 registers with the port 15, and the lower terminal 21 of the conduit 19 is in communication With the scavenger orts 82 a supply of air under pressure will e recelved from the pipe 11 and will be transmitted to the cylinder 5 and out of the cylinder-through the conduit 20,

' the conduit 13 and the port 7. The cylinder is cooled by this circulation of air therethrough.

As will be seen by referring to the drawings the ports will be in this position after the explosion, and with the movement of the piston 14 in the direction of the cylinder ead the ports 15 and 16 will be closed by the valve member 17, when the piston is at the end of the return stroke. As the valve member 17 rotates on the piston 14 the port 26fwill be moved into position to receive the combustible mixture from the port 6 which combustible mixture is compressed by the movement of the piston toward the cylinder head when itis exploded in the usual manner. While I have shown my invention as applied to a four-cycle engine it will be understood that it may be used on. other engines.

. In the operation of the engine the ratchet tooth 31 moves the ratchet disk 22 and the valve member 17 one-eighth of a revolution at every revolution of the main shaft so that with every second revolution of the main shaft one of the ports 26 will be disposed opposite the port 6. In this way the cylinder is charged with the combustible mixture with every second revolution of the main shaft and the combustible mixture is compressed and fired as is customary in 4-cycle engines. When the pistonis moveddownl again the main shaft has made a complete revolutlon and the valve member 17 has made one-eighth of a revolution which hasl moved two of the. ports 18'into communication with the ports 15 and 16 to clean the cylinder of the products of combustion.
