Application filed May 17, i919. Serial No. 297,783:
To all whom it may concern:
Be it known that I, LoUIsSTnnenL, a citizen of the United States, and resident of New York, in thecounty of New York and State of New York, have invented certain new and useful Improvements in Explosive Engines, of which the following is a specification.
The invention relates essentially to nulticylinder four cycle engines, of the kind in which a tubular rotary valve controls the intake of the combustible and also the exhaust of the products of combustlon from the cylinders.
One of the objects of the present invention is to provide the valve with duplex ntake and exhaust ports tosuccessively register with the port leading to each cylinder so that the valve can be revolved very slowly to obviate breakageof the parts whilev the crank shaft is runningat'a high rate of speed. 7
Another object of theinvention is to. pro videa cylindrical valve of smaller diameter than the bore of the casing so as to compensate for the expansion, and contraction caused by the heat generated from the explosion Another object of the invention is to equip the valve with. devicesfor forcing it against theborein order to eliminate leakage of the combustible.
The invention also includes means connectedto-the device for automatically lubrieating the valve,
The invention resides in the novel combinations hereinafter described and claimed, reference being made to. the accompanying drawings inwhich Figure 1 represents a vertical longitudinal section of an engine embodying-this invention.
Figure 2 is a sectional end view showing the plunger. 4
' tion-of the-valve and its casing.
Figure 3 is a. horizontal longitudinal See Figure Lisa vertical longitudinal section of the valve. I
Figure 5 is-.-a-transverse section taken along the line- 5-5 of F igurez l.
Figure G'is' a: similar section taken along the" line 6-6 of the same. I, Figure 7 is a similar" section taken along the line:77 of thesame, showing the valve and its casing;
ports-29 are formed in the circumference and chambers 32,
taken along glue or motor having a series of cylinders 12 coupled together, each provided with a piston 13made to reciprocate in the cylinder by the explosion of a combustible. The pistons are connected by meansof rods 14' to the cranks l5 formedon a driving shaft .16 mounted to rotate in bearing 17 extending from the lower portions of the cylinders. A Water jacket 18 is provided for cooling the cylinder as is wellknown.
Surmounting the cylinders is located a cas1ng 19 having a longitudinalibore 20 open at each end. A water jacket 21 partly surrounding the bore is made to cool the casing.
he casing'is equipped with a plurality of ports-22 for connecting the interior of each cylinder 12 with the bore 20 the function of which will be scribed;
In the center of the a compartment 23 bore; and fuel from a carburetor into the compartmerit where the fuel is heated before it is distributedinto the cylinders.
A cylindrical tubular valve 25 for'conof the casing; hereinafter decasing 19is located partly surrounding the trolling the distribution of the combustible is loosely arranged in the hereof the easing and front andiear covers 26 secured to each end of the casing eliminate longitudinal movement of'thevalve. Duplex intakeports27 disposed in the central portion of the valve conduct the combustible from the compartment 23 into the valve. A series of duplex inlet ports 28 and exhaust of the valve to coact with the ports 22 inv the casing.
A number of windingpartitions 30 in the valve divide it into duplex passage-ways 31 the passage-ways being adapted to lead off the products of combustion', while the chambers constitute the intake for distributing the combustible mixture to the cylinders; A pipe '33 fitted to the rearcover 26. and communicating with t the passages.v will conduct. the products of a plpe connection2 t conducts the at predeterminedtimescombustion from the cylinder when one ei the other of the exhaust ports 291s in register with a cylinder port.
The forward end of the valve is eduipped with a journal 34 passing through a hole in the forward cover 26 and on its outer end ismounted a worm gear 35 meshing with a worm or tangent 36 fixed to one end of a vertical shaft 37 extending downward. The other end of the vertical shaft carries a small, worm 38 enga ed by a worm gear 39 on the forward en of'the crank shaft. The rotation of the vertical shaft is uniform with the crank shaft but the upper worm and gear have teeth of different pitch and the gear 35 being considerably larger than the'worm it will revolve the valve in theratio of one revolution to four revolutions of the crank shaft. In this arrangement each stroke of the piston will transmit one-eighth of a revolution to the valve. In other words two revolutions of the crank shaft will complete four cycles and transmit one-half a revolution to the valve.
A timer 4.0 ofsuitable construction is interposed between the worm gear and the forward cover and it can be connected to operate in the usual manner. As indicated in Figures 3 and 4: the chambers 32 in the valve receive the combustible from the compartment 23 through the medium of the central ports 27 when adjacent to the compartment. Hence when one of 1 the'inlet ports 28 register'with a'port22 35.leading into a cylinder thecombustible will fiowinto that particular cylinderand be exploded. The rts are timed to permit the first cylinder to explode the combustible, .the second to compress, the third to exhaust,
mixture. Each cylinder has a single port leading to the upper part of the cylinder and cooperating with the valve toat times intake and at other times perform the funci145 tionslof exhausting the products of comv .bustion after the explosion. It will be readily understood that when one of the.
iexhaust ports is in the. cylinder ports .50 it through one of the alignment with one of the products will flow duplex passages 31 and wont of the conduit 33 at theend of the valve.
As indicated in Figure 10 the four'figures cfnom tdpito bottom illustrate cesswe strokes of the engine. Thelposition cc fiemflthe various-pistons and their relation to each otherwhen'the front cylinder is about to fiX'W IS :shown in'the ugper figurer The wplstons move downward uring' the explomien and strokes and they move-up-:
mfi ward-during the compression and exhaust 5 strokes *4 In this arrangementg the front cyl firesfi-rst, then the second cylinder,
ala ine fourth cylinder, and lastly the thirdt dfiyl nder. -='The four operations .of'wthe cycle 1 y a M wnamely nspctlbm compression,' explosion and and the fourth to intake the combustible the four suc- -moves radially against the fully compressed and ready for ignition, the
second piston is at the bottom of the suction stroke just at the beginning of. its comprcssion stroke and the valve 25 cooperating with the ports in both cylinders is closed. When the piston in the third cylinder starts moving up on its exhaust stroke. it will force the products of combustion out of the cylinder through one of the passageways of the valve. The piston. in the fourth cylinder is then. moving downward and when one of the intake passageways is adjacent to the port 2 2 it permits a charge of gas to be drawn into the cylinder from the carburetor.
By having the valve loosely mounted in 86 the bore of the cylinder it-compensates for the expansion and contraction of the valve produced by the heat generated by the explosion. The valve can thus revolve freely whether it is expanded by the heat or contracted when it 60015 of. Inorder to at alltimes press the valve against the bore a pair of plungers or buffers 41- are rovided as indicated in Figures 1 and 2. Each plunger is slidingly mounted in a '95 sleeve 42"projecting upwardly from the cylinder and it includes a stem 43 having a channel 44with a socketj45 above the channel. The lower endof the plunger carrise .a counter-sunk felt or asbestos ad or *1 wick 46 communicating with there annel.
A coiled spring 47 presses the plunger against the periphery of the valve, thus forcing the valve onto its seatto efi'ectively eliminate leakage of the combustible lietween the joints. "The upper portion of the spring strikes onto the inner surf'acelof a nut 48 having a central opening for the stem to slide, and the nut can be adjusted to expand and compress the spring thereby llo transmittingmore-or less pressure onto the plunger.
A vertically positioned oil suppl pipe 49 telescopes into thesocket of the p un er. The'socket of the plunger forms a mg connection permitting the pi e to remain stationary while the stem an itsplunger.

It should be noted that the valve is given one-half a revolution to four strokes and the valve intakes and exhausts once during the cycles. There are two intake and two exhaust ports circumferentially in aline with each other made to cooperate with the single port leading into the cylinder so that at a complete revolution of the valve each piston has made eight strokes while the valve has governed the admission and expulsion twice.
I claim:
1. An explosive engine comprising a plurality of cylinders each having a port to alternately intake and exhaust, a casing having an inlet, a tubular rotary valve with a pair of intake ports to at times register with the inlet, dual intake and exhaust passages in the valve for conducting the combustible, duplex peripheral intake and ex haust ports continuous with the passages to individually register with a port in acylinder and a port in the casing coacting with the exhaust passages.
2. An explosive engine comprising a plurality of cylinders each having a port to alternately intake and exhaust, a casing having an inlet, a tubular rotary valve with a pair of intake )orts to at times register with the inlet winding dual intake and exhaust passages in the valve independent of each other to conduct a combustible, duplex peripheral intake and exhaust ports continuous with the passages to individually register with a port in a cylinder, and a port in the casing coacting with the exhaust passages.
8. An explosive en ine comprising a casing having multi-cyhnders, a rotary cylindrical valve controlling the intake and ex haust arranged in a bore of the casing a plunger cooperating with the valve to press it against the bore of the casing, and means slidingly connected to the plunger for supplying oil to lubricate the valve.
