' INTERNAL-COMBUSTION 'ENGINE Application ined June 2i, 1927. sriai Nb. 200,410.

This invention relatos to an improvement in an internal combustion engine and has for its object to provide such a type of engine in which a minimum of moving parts will be utilized, thus greatly simplifying construction and the likelihood of wear orr breakage. y

A further object of this invention is to provide a novel form Vof construction in which many of the important parts found in internal combustion engines at the present date, suchas chains, gears and the Alike arev as may hereinafter appear, in view, I have devisedr the embodiment of my invention disclosed in the accompanying drawing and' more particularly pointed out in the claims appended hereto.

Reference is to be had tothe accompanying drawing, forming a part hereof, in which, f i

4Figure 1 is a vertical sectional view or my improved engine;

Figure 2is a sectional view at right angles to-that shown in Figure 1, suoli View being taken on the line 2-2 of Figure 1', looking in the direction `of the arrows;

Figure 3 is a sectional view on theline 3--3 of Figure 1, looking inthe direction of the arrows; and f Figure l is a sectional view on the line 1 -4150i Figure 1, looking inthe direction of the arrows. y, Throughout the various; views of the drawings, similar reference characters designate similar parts.`

In the embodime "t of my-.invention disclosed intheaccompanying drawing, I show my improved engine as being of the one cylinder type It willlbe understood however, that a multi-cylinder engine may be readily" constructed'by a duplication ofthe paitsand arrangements to be hereinafter described. Y n Y Itwill therefore be understood that in referring to the cylinder, `piston and other parts, this shall be .interpreted as applying may be employed in various types oit-en gines.

In the accompany drawing, 1 indicates an inlet manifold, which may be supported in any suitable frame or casing and which mayy be connected to a carburetor or other mixing device for supplying an explosive mixture through the internal passage 2 of the manifold l. This manifold 1 acts as a support for a stationary piston 3, said piston being connected to themanifold 1, by means ofa t-ubular arm 4. This tubular arrn/i may,.if Vdesired,'be formed integrally with the piston 3 or'it may be a separate piece bolted or otherwise secured thereto. Said armliL is provided with a bearing 5 which extends around the manifold 1 so that a pivotal connection is established between said "manifold 1 and the piston 3. The arm iis also provided with a continuous internal passage or Y.

bore 6, which has its upper end locatedin registration with an opening 7 so that the explosive mixture fed lfrom a carburetor through the passage 2 in the manifold l will pass through the opening 7 and down through the bore 6 and into the cylinder of the engine as willbe hereinafter explained. TheV lower end of the supporting arm 4 is normally closed by a valve 8 which is held upon its seat by a spring 9 until opened by suction to permit the entrance of explosive mixture into the cylinder 10, as will be hereinafter explained.

The cylinder 10 just mentioned is `arranged to reciprocate relatively to ,the stationary'or fixed piston v3, this action being just the reverse of the ordinary internal combustion engine, wherein the cylinder is usually stationary and the piston reciprocates therein.

The piston 3is providedwith the usual packing rings 11 which bear against the inner wallsof the cylinder 10 in the conventional manner and pre-vent leakage.

i The piston 3 is provided with a pair or inlet valves `12 which are normally heldin closed position bysprings 13. These valves are intended to be opened at the propery time to permit explosive mixture to enter below the piston 3 and thereaftery be compressed by an upward Amovement ofthe cylinder 10. their respective seats, tappet means 14-is provided, such means consisting of a cylindrical member having a central boss15, and a circumferential flange `16.

Said tappet member 14 is carried within and moved `with For raising the valves 12 'from lio i' be interposed between these two flanges so ttl . pipe 25, provide a number of spaced bale the cylinder 10. on its movement relatve to the piston 3. rlhe tappet member'lel is northe bossll and which bear against the outer face Yo't the arm or sleeve Ll and prevent leakage of explosive mixture between the part la and thetace of the sleeve 1l. l

lt will be understood 'tromthe foregoing that when the cylinder descends to substantially the pointed indicated in Figure 2, the part 14 will come in 'Contact with the upper endsot the stems on the valves 12 and will by a resilient, yet tirin pressure, force said valves from their seats and peinit. the entrance of explosive mixture to points below the piston The cylinder 10 is provided with cooling tins 22 and at its lower end it is provided with a circumferential ilange 23, against which rests a llange 2st, located on the upper end of a tubular exhaust pipe 25. Said flange 2.4 may bebolted or otherwise secured to the flange 23, and aV suitable gasket may that ya tight joint will result.

upper end or entrance with a valve seat intended to receive an exhaust valve 26 which is normally held on its seat or in which bears against a crossing 28 located in the pipe 25. The opposite end of said spring bears against a pin 29 extending through the valve stem 30.

y The outer surface of the pipe 25 is provided with cooling tins 31 and inside of said plates 32 for quieting the engine exhaust.

Adjacent to the lower end ot the pipe 25, is providedr a plurality of openings or holes 33 to provide the exit of exhaust gases in thev ordinary way. The lower'end oi' the pipe 25 is provided with'a bearing 84 which embraces the crank part of a crank shatt 36. lt will be understood that this crank sha-ft may be supported at its ends in the conventional kway upon suitable bearings which are not `shown and any of the well known types ot' oil feed or lubrication may be employed.

. At is shown a cam which islprovided on a part-oi the crank shaft so that at the proper time, said cam will come ink contact with` the lower end of the valvestem 30 and raise said exhaust valve 26 from its The tubular member 25, vwhich is in the. nature of an exhaust pipe is provided at itsA seatto'permit the' exhaust gases to enter into the pipe 30 and pass out` of the same through the openings 33. In order to permit free operation of the cam member 37, the bearing Blfon the end or" the pipe 25 is slotted or-split as at 38.

From the foregoing, the manner in which my improved engine operates will be readily understood. As was heretofore explained, the explosive mixture passes from a carburetor into the passage 2 and into the bore 6 of thek sleeve 4. At this point, the cylinder moving upward creates sutlicient suction to cause the valve 8 to be raised from its seat with the result that explosive mixture passes through the end of the bore 6 and into the cylinder above the` piston '3. Vhen the downward movement of the cylinder takes place, 4the tappet member 14 comes into contact with the upper ends of the valve stems l2and forces these valves from theinseats then movesupwardly, the valves 12 thenA closing and the explosive mixture is compressed between the piston 3 andthe lower end ot the cylinder 10; and exploded by means of the spark plug 39, which receives its spark from any suitable source ot; electric current. The cylinder thereupon begins' its upwardr movement, the exhaust valve `26 being openedby the cam 37 `to permit the escape of exhaust` gases through the exhaust pipe 25. n

It will be seen from the design of engine disclosed that a minimum of parts is used, the exhaust pipe 25 being utilized asa connecting rrodfor the reciprocating cylind-er 25. It will also be seen that the parts are so connected and assembled that the same may be dismounted readily for cleaning and renewing andv that the yengine is readily cooled since the cylinder rather than the pistonis movable and*` that the use of va* rious gears, Vdrive chains and the` like commonly employed in internal combustion engines is obviated.' i

Having described invention, it is obvious that the same is not to 'be restricted thereto', but is broad enoughL ton coverl all structures 'coming within the scope of the annexed claims. f
