Specification of Letters Patent.

Application filed March 27, 1918. Serial No. 224.976.

To all whom it may concern.'

Bc 1t known that we, Ricuauo lliccuuax and HERMANN 'onni-zrucx, subject of thc rotate about a fixed crankshaft.

I.The purpose of the invention is to,iin prove ,the construction and operationl .of such a rotary type engine by the provision Aof noval fuel-feeding devices, with a `view to increasing the power of the vmotor and also lessening its cost of operationl)y ohtaining a maximum o vver from the .fuel consumed per unit o time. `More specifically, the lnvention resides in feeding fuel Ito rthe outer ends of the cylindersthrough inlet valves located `at the outer ends 0f the cylinders. This is accomplished in a gen- Aeral Way by connectingveach cylinder', during a portion of its revolution, with a fuel chamber from which the Vcylinder is supplied. As the fuel chamber is independent of and entirely removed from the crank case or crank shaft, it is possible to secure u uniform mixture of fuel in its state of `original purity.

By having the fuel inlet valves located in the outer ends` or heads of the cylindcrs,the structure is rendered practicable for aeroplane application, in which cylinders must be made from fol-gings throughout, so as to ,obtain the necessary strength and equilibrium.

In the present structure, the intake chamber is separated from the exhaust so that the danger of backfire is eliminated. the exhaust taking place durin a different portion of the c linder`s revo ution from that of the fuelceding operation.

One method of carrying out the invent ion involves utilizing a Stationarysegmental channel section which coperates with a movable channel rin or section that travels with thc cylinders. he channel ring is nl circular forni and in communication willi term is ineant Vshow-,lng the position oft valve at ,the completion of the fuel-feeding cncli cylinder al thc outer end of the latter, and the iortion of the channel ring positioncd :Lilian-cnt to the stationary channel scure at any given moment, forms therewith flic fuel chamber, and serves to admit fuel to such ycylinders as have their valves in the open position and are in communication with ,the fuel chamber.

To theseiand other ends the invention consists inv certain improvements and Vcombinations of, parts as will be hereinafter more fully Vdescribed and pointed out inV the claiins following the specification.

The novel and nnderlyi u features of the improrenient inayvhe carrie ,out inra variety oiwaysand for the purpose ,of illustrating onepossiblel embodiment., the disclosure comprises a frame' A which supports a series of cylinders B. The several cylinders B and the frame A rot-.itc about a common center or fixed crank shaft (l. The latter has a conunou crank connected to cach one and the pistons B hv means of a connecting rod B2.

Each cylinder is provided at its outer end or head willi n port B3 controlled h v a valvc B. The lat-tcl' is inountedon u valve stein ll" and is opi-rated for opening und closing nfl lll

ating means, by

in a manner that will be described presently. V A

The frame A and cylinders B have connected thcreto a circular channel section E which rotates with the cylinders and is connected with the ports B3 by means of communicating conduits E. The channel E is continuous and uninterrupted and during a part of its rotation cooperates with a s ta tionary' complementary channel section which is in communication with a fuel supply and forms With the moving channel, a fuel chamber. y

To this end we employ the stationary segmental channel section F shown in Figs. 1 and 3. The channel section F is closed at its ends by thewalls F and is connected with a carbureter or fuel supply by means of a pipe F. The channel section F, which is' stationary",i is r` preferably provided with thin plates K in the form of extensions or flanges which `areattached by means of screws F3 and engage corresponding grooves E2 in the .channel section This ali'ords an effective' sealiiig means between the channels so as to constitiitea closed fuel chamber. between the eny wallsF 'of the stationary section. i'f

Assuming the cylinders and frame to be traveling in an anti-.clockwise direction, as shown in Fig."1,xat.the beginning of a cycle, the inlet valve is opene as tliecylinder reaches the topq position. As ittra'vels downwardly to the left and comes `in communication with" the'fuel fuel'is taken in while at thesaxne t'me'th'e piston travels inwardly and causes a suction. Asrthe cylinder, reaches the end of tlifuel chamber, its valve iszautoriiatically closed, as shown in Fig. 7, and compression'ftakesplaee by the outward movement of thepiston during the outward travel of the cylinder. When the latter again reaches its uppermostposition, as shown in Fig. 8the ex losiontakes place, forcing the piston inwar lyand causing the cylinder to travel from the position in Fig. 8 to that of 9. During this last mentioned'movement, 'which comprises the first half of the 'second vreaollition of one cycle, means rasa-ins closed unal' a reaches the position'f'of fFi'g. The valve then opens and the burntgase's are exhausted during the upward movementof the cylinder', acycle bein T"'rnpl'e'ted at 'theend of two 'comple-tc revo utio'ns Vof" a' cylinder. The' valve-operwhich the position ofthe valves is automatically governed, will now be described.

Mounted upon the fixed crank shaft C is apinion C2 which is also stationary and engagesA a gear G. The latter is journaled in the cylinder frame A and is geared tov the pinion C2 inthe ratio gf two to one so that the gear G will be rotated through one complete revolution only once for every two revmoving parts of the olutions of the frame and cylinders. There are a number of gears G, one for each cylinder andA valve, and they are mounted upon arbors (i2 which are also provided with lixed cams G3. The latter engage connecting rods G* which operate the valve levers i5. These are ivoted at G and have) end portions G1 which contact with theA outer ends of the valve stems B5. The valves are held normally closed by means of springs B. As the cylinders and frame rotate about the fixed crank shaft, the cams G are turned once for every two rotations of the frame and this causes each` valve Bto be opened and closed so as to complete the cycle, illustrated in Figs. '6 to 9, inclusive.

It is desirable that the fuel chamber be at no time in direct communication with the atmosphere, and to accomplishthis purpose, the end walls F" extend upwardlyintfsubstantial contact with theouter wall of the channel section E' and their edges extended peri herally to afford surfaces `F"whicl 1`ffare pre erably of at; least 4as grea'twidth Aas the openings E" ,in the section E. This'ar'rahgement prevents the' openings E` from being partially in communication withtlie 'stationary section "F and'partiallyin communication with the atmosphere; 'a'nd 'insures their being cut oil from atmospheric communication before 'theiinlet chamber is iincovered. fr .f

. YThe "overhead valve arrangement perriiits makingA the cylinders from forgings, rcsultingin a. balanced motor With'the equilibriuma that'4 is necessary, particularly tolaeroplane operation. The aseous fuel',mi'xtfureisi` readily Jed at all times in thecorrectlprportions without coming into contact with any lf the motor ,or' its lubricating oil, as is the case where the fuel is fed through a chamber surroiliulin' Lthecrank shaft. further important a vairtag'eof the invention rcsidcsin separating the intake chamber from the exhaust zone, as "this reduces and practically eliminates theypo'ssibilitv of backfire. Y Y f The essential features of ourV improve ments are considered to be the supplvmg of fuel directly to the outer ends of the walls of a rotary tvpc motor from a fuel cha'rnber which is independent of tlie crank" shaft and oil feeding devices, and acc'omplishing'this by periodically bringing each cylinder into communication with a fuel chamber and opening the supply valve at such time. lt is not intended to limit the invention to the structure described herein or any close approximation thereof, as the'purposcs cairbe equally well accomplishedby various modiicd arrangements of valve-operating means and communicating fuel feed instruxnentali ties without departing from the spirit of the invention or the scope of the following claims.
