INTERNAL-COMBUSTION ENGINE,

Specification of Letters Patent, I Patented May 30, 1916,

Application filed January 2, 1915. Serial No. 57.

To all whom it may concern Be it known that I, CLARENCE D. MILLER, a citizen of the United States, residing at the city of Philadelphia, in the county. of Phlladelphia and State of Pennsylvania, have invented certain new and useful Improvements in Internal-Combustion Engines, of which the following ,is a specification.

My invention relates to that class of internal combustion engines known as a rotary valve type, in which puppet valves are not used as I use a circular sleeve or ring in place thereof withan opening or port, the sleeve usually being slit or cut and when out it is usually at or near the said opening or port. This form of motor. and valve'is more simple in construction, cheaper to manufacture, and has less parts than other types of motors which use the puppet or sleeve valves.

The principal objects of the present invention are to improve internal combustion engines, more particularly in respect to the valves and their accessories; to reduce the number and simplify the construction of the valve parts and so to provide a, comparatively inexpensive internal combustion engine; to provide for holding comparatively high compression and thus elfectingeconomy in operation; to so construct and combine the parts that they will be quiet in operation, will not be interfered with bydeposition of carbon and will require comparatively few repairs which, as well as adjustments, can be readily made; and to avoid the use of parts which are expensive to make and require re-grinding at intervals to maintain. them in proper condition.

One object of my invention includes an internal combustion engine having a sleeve or ring or sleeves or, rings mounted upon a hollow stud or shaft with a collar either integral with said stud or shaft, or bolted or screwed to said stud or shaft. In referring to'the ring or sleeve I do not confine myself shaft being hollow, with an opening or port,

to allow an incoming charge of gas or vapor to enter to produce the necessary explosion,

erly and thus allow the expulsion of the ex with means for permitting the gas or vapor 55. after it has been exploded to' be expelled or passed out through the opening or port.

Another object of my invention covers the use of a ring or sleeve, being split as described, and in which the natural expansion 0 and contraction of the metal has the effect of opening or closing the valve. to produce and retain the described and requisite compression necessary in an internal combustion engine.

Another object of my invention is to have the sleeve or ring so mounted on the stud or shaft that when the gas or vapor is admitted through the opening or port, the sleeve or ringwill partially rotate or revolve with the stud or shaft in such a-manner, that when the charge of gas or vapor is admitted, the I sleeve will rotate or partially revolveprophaust gas or vapor after explosion.

Another object of my invention'is to have the sleeve or ring on the stud or shaft mounted in such a manner that the opening or port registers so that the two ports, namely the sleeve port opening and the port. so opening in the stud work in unison with the opening or port in said stud or shaft.

Another object of my invention is to have the stud or shaft with the opening or port have a collar bearing upon a thrust bearing over or under said collar, so that the partial rotary motion may be accomplished .without undue strain or wear on any of the parts. I

' Another object of my invention is to have the stud o'r shaft with the opening or port havmg a collar, and having means where- 'by a'gear or gears-may be attached to or fastened on the said stud or shaft, which 4 gear or gears are in turn connected with a shaft running at or about right angle thereto, the said latter shaft having gears which mesh with those on the stud or shaft for the purpose of proper timing of the revolutions and explosions of the. motor.

Another object of my invention is to have the sleeve or ring with the opening or port, the stud or shaft, the collar, and the gear or gears in such position that a cap or housing may be placed over the gears withoutv dis- 105 turbing, changing, or interfering with the alinement orproper working of the parts of the internal combustion engine, thereby a after described and specifically combined as fnot running.

producing a new, useful, and cheap method of manufacturing an engine of the type de-. scribed, that is accessible in all its working parts merely-by removing a cap or housing, either when the engine is in operation or My invention also covers the construction of an internal combustion engine as above described, but is not limited to the use of one sleeve or ring, but to any number that maybe desired to accomplish the same or' equivalentv purpose.

My invention also includes various im- I provements in the construction of internal combustion engines and in the parts herereferred to, and I do'not limit myself in either my specifications or claims to the Inthe drawings 1,is a valve casing proparticular forms of the parts described and illustrated, but other forms producing the same or equivalent results are covered by my y of an internal combustion engine embodying i 35 features of the invention. Fig. 2, isa sec:

tional view drawn to an enlarged scale and illustrating features of the invention. Fig. 3, is a perspective view of one of the parts detached, and Fig. 4:, is a transverse sectional view of Fig. 2.

vided with a cylindrical opening that extends clear through it and constitutes a valve seat and with an intake port 2, and an exhaust port 3. The valve seat is pro vided at the end thereof where it communicates with the cylinder 4:, and a contracted shoulder 5. At the top of the valve seat there is an enlarged shoulder 6.

7 is a stud provided with a collar 8, and with a hollow valve body 9, having a port 10,'formed through the wall thereof. The elements 7, 8, and 9, may be made integral or they may be suitably connected together so as to constitute in efi'ect one piece. The rim of the valve 9, near one-end has a bearing in the portion 11, of the valve seat beyond the shoulder 5, and the collar 8, has a bearing in the valve seat inside of the shoulder 6. p

12, is a bearing ring through which the stud 7 passes and which is seated upon the shoulder 6, and which is provided with an extension that is seated on the collar 8.

13, isa' locking ring that encircles a boss aieaeee on the bearing ring and has screw and thread engagement with the valve seat and serves to hold the bearing ring.

14, is a sleeve split as at 15, and provided with a port 16, alined with the port 10. This split sleeve '14, is arranged between the valve 9, and the wall of the valve seat and extends from the shoulder 5, to the inner face of the collar 8. This split sleeve is contracted when it is put in place and hence it tends by its resiliency or springiness to expand and hug the inner face of the valve seat. A pin 17, is shown as an example of a means for keeping the ports 10 and 16, opposite each other. is a worm gear 18. The drive shaft 19, is provided with a number of worms 20, one for the worm wheel of each valve, and the valve bodies 9, of the difi'erent cylinders L, are so set with regard to their ports 10, and the inlets and exhausts that the operation of the various pistons and cylinders are properly timed. The shaft 19, is shown as driven from the crank shaft 22, by means of a shaft 23, and gearing 24:.

25, is an oil feeder. The valve casing is provided with walls 26, which together with the removable cover 27, constitute an oil receptacle in which the valves and their accessories are arranged. When the cover 27, is removed, access may be readily had to the valves and their parts.

The split sleeve 14, is contracted when it is arranged in the valve casing and it tends to open so that it hugs the curved wall of the valve chamber in which it is arranged. The valve chamber is subject to expansion and contraction under the" heat to which it is exposed but the split sleeve by expanding and contracting compensates for this while at the same time properly holding the compression'in the cylinder so that the valves can be easily rotated and do not tend to stick or 3' am. The compression in the cylinder is not only held by the sleeve but also by the collar 8, in cooperation with the bearing ring 12.

It will be obvious to those skilled in the art to which theinvention relates that modifications may be made indetails of construction and arrangement without departing from the spirit of the invention, hence the latter is not limited as to those matters or in any way further than the prior state of the art and the appended claims may require.

What I claim is:
