Be it known-that I, LOUIE citizen of the United'st'ates, residing at Kansas City, in the county of Jackson and State of Missouri, have inventedcertain new and useful Improvements in RotaryValves;
and I do declare the following to be a full,
, clear, and exact description of the invention,
such as will enable others skilled in the' art to which it appertains to make and use the same, reference being had} to the accompanying drawings, and to-"the letters and figures of reference marked thereon, which form a part of this. specification.
My invention relates to a rotary 'valvefor explosion engines, and has for tsprmcipal object to provide a device of that character whereby the intake and exhaust of the en gine cylinder is delivered through a common port in the valve member, at roperly spaced intervals relative to each ot erfand to the operation of the sparker device.
It is also an object of the invention .to provide the valve with a'packing member, which may automatically ad ust itself to 1nsure close contact against the cylinder Wall to prevent the escape of live or exhaust gases about the periphery of the valve at the sides of the valve por In accomplishing these objects I have provided improved details of structure; the preferred forms of which are illustrated in the accompanying drawings, wherein -Figure-I is a perspective view of an en-- gine equipped with a rotary valve, constructed in accordance with my invention. Fig. Ill is a' central, longitudinal section of the engine cylinder and valve, with its opcrating mechanism. Fig. 111 is an end view of the cylinder head detached from the cylinder. Fig. IV is a transverse section on the line Iv -IV, Fig, II. Fig. V is a detail perspective of the valve. Fig. V1 is a similar view of the expansible valve ring.
Referring more in detail to the parts 1 designates an explosion engine cylinder, which is mounted on a bed 2, and provided with a piston'3, having a connecting rod 4 leading to a crank shaft 5, which is pro vided with the ordinary fly-wheel 6. Fixed on the cylinder 3 is ahead 8, both the cylinder and head having water jackets 9 communicating through ports 10 in the head flange 11 and fed through the circulating pipes 12-13. The cylinder head is provided. with A. SHERMhN, a I
spaced from the intake port and provided an intake port 15-which communicates with a carbureter 16 and'has an exhaust port 18 watt conduit 19 for conducting the exhaust to a distance from the eng1ne.-
Revolubly mounted in the head 8 is a valve 21 comprising a ring which fits snugly :within the head chamber andhas an interior web 22 extending thereacross and preferably formed integraltherewithi Fixed rigidly to theweb 22, in any suitable manner,
is a rod 23 which extends. througha stuffing box 24 in the end of the head and is connected with a gear wheel25' that meshes with a pinion 26 on a shaft 27thatis journaled in bearing 28011 the cylinder head and the'bed of the engine, and has a beveled ge'arwheel 29 meshing with a mating 'gear 30 on the '1 crankshaft 5. 3 The valve ring 2l has an annular groove 32 therein, and located within the groove 32 is a port 33, adapted for registration with 'the intake and exhaust ports 1518. Integral with the ring 21, and pro-' jecting into the groove 32, from one edge, thereof, is a lug 34,. Seated loosely within the groove 32 is an expansion ring 35, having a socket 36 into which the lug 34 on the valve ring "is projected to hold the ring against rotary movement on the valve, but without interfering with its expansion and contraction. The ring 35 has a port 38 held in registration with the valve port 33 by the lug and socket connection between the ring and valve; the ring being preferably broken at the sides of the port, as illustrated in the drawings.
The head of the cylinder carries a spark ing device 40, having a circuit wire 41leading thereto and connected with any suitable source of current (not shown). Mounted on the cylinder head is an arm 43, having a brush 44 wiping a commutator 45 on the be exploded when the piston is in the proper position.
In using the device, presuming the parts to be constructed and assembled as described,
when the engine is in operation, the valve is. revolved through its driving connection with the crank shaft to bring the valve port into registration with the intake port in a the cylinder head to take in a charge. After the charge has been taken in, the secondary circuit is closed to explode the charge and drive the piston through its working stroke.
After the driving stroke of the piston is completed, the valveport registers with the exhaust port in the cylinder head to clean the cylinder. p v By providing the ,valve with the expansible ring, the ring takes up wear of the valve so that a tight joint. is always present between. the valve and cylinder, thereby obviating by-pass of the intake charge or exhaust from the valve port into the cylinder and about the rotary valve.
It is apparent that, with this construction, the valve may have a loose fit inithe cylinder to provide for easy reciprocation, as
' Copies of this patent may be obtained for the ring prevents the escape of live and exhaust gases between the valve and cylinder secure by Letters-Patent, is:
A. rotary valve comprising a cylinder, a separate head attached to the cylinder and having an intake chamber communlcatmg with the cylinder chamber and having spaced ports in its circumference, a body ring revolubly mounted in said head and havlng a single port adapted for communication with either of the head ports and having'a circumferential groove, an expansion ring seated in the groove and having an opening in constant communication with the ring port, and means for revolving the body ring from the exterior of the head.
In testimony whereof I aifix my signature in presence of two witnesses.
