ROTARY iNTEBNAIfconBns-TION ENGrNE. w

Be it known that I, FREDERICK WrLF-RED GOYETTE, a citizen lof Canada, residing ati Los Angeles, in the county of Los AngelesA and State of California, have invented anew and useful Rotary Internal-Combustion Engine, of which the following is a speciii cation.

It' is of the provide an'iinprove'd practical internal c0in-.

ustion engine in which the eX ansive force' is applied to immediately impe a'rotary eleansinn4 may be taken; -to guard against eakage of' the -expanding medium; to provide for ready reversal ,of the engine; to-

make 'provision for v readyE stopping and starting of the engine, and also to provide for impeding the engine with cushion means for the purpose' of .holding back automobiles and like vehicles on hills, without'recourse to a brake.

This engine-is designed to v'be' sup lied -with compressedexplosiv'e gas, and sue gas' may be suppliedby any form of compressor either drivendirectly by the engine or by.

separate motive power, or J in some instances the engine may be o erated b coinpressed gas fed from a ho der in W ich it .maybe contained for transportation or storage). Y

t t \v Anobjec 'of the' invention is toprovide for the delivery fromv the compressedassupplying device to the eplqson; cham er, of appropriate Clmrges "Ofli'asfv .fmfl t0' cause the saine to explode at the Properttime to drive the rotary element, which foriconjyen- 5 ience I shall hereinafter term the psto j It will -be apparentthat 'some featur Sof the invention may be-einployed in r enginesA driven by expansive mediaAll than explosive niixtures,and I may e ploy the same in rotary steam engines.

1- is -an annular shell providedwith a cylindrical bore -2 that extends 4 entirel through the shell and provided in the wail of the bore with a channel 3 that is eccentric to the bore and Jforms a crescent-shaped cavit extending therearound approximate y 300 degrees more or ss, leaving an arched portion of the wal of the bore straight., .smooth and' uninterrupted from end to end ofthe shell. The bore 2 has par'- *allel Walls a, as clearly seen in Fig. 3, that .are unbroken except by the channel 3 and ,by two annular channels 4, 5, which are arh 'fisy ranged to receive packing- rings 6, ,7, `t0 -inake a tight joint between the rotaryhe'ad or piston S'and'the annular shell 1 toi revent escape of the expansive medium a ong the face of the piston. Said piston Slis cylindrical and is constructed to forma close running fit with the walls .a of the openin 2v 'of the shell, and is provided with annu ar' which 'is provided jivitl'i one or more radialV I'do not limit theinvetiwpn to the exact form shown, norto the character of @cpan-.

ways 1.157 a radial way being provided for each ofthe gates'. The periphery of the ro- -'tary piston5 is-smchth, solid and unbroken eirce'ptzat the mouths of'such. radial way or ways, each'of which extends along vthe piston face a' distance corresponding to the width of the crescent-shaped channel 3 into which each gate iswadaptedto project when the rc- 'ta'tion of. the pistonbring's it to that side of t le shell. The gates are duplicates, and the d ription of one applies to both.

16 designates a spring to project thegate outward to engage the shell and to form a barrier across the crescent-shaped channel.

- looseness or wear.

The gate'comprises two relatively movable sections b and c, and a wedge-shaped head 17 whereby the gate may expand to take up Said spring 16 o crates upon the wedge-shaped head 17 to orce it Y outwardly to act upon the loose sections l), c,

of the gate 14 to press said sections toward the lateral walls of the channel at the same time the gate presses against the peripheral AWall thereof to tightly close the'passage-way along the channel as the gates move therein.

19 designates a rotary valve at one edge of the smooth, uninterru ted arched wall and atx one end or tip of t e channel 3, and 20 designates a pipe-to deliver compressed gas'or explosive mixture to the rotary valve 19 which is provided with a ort 21 through which to receive the gas, and) through which to deliver the same or the roducts thereof, or both, to the tip of the c annel as the rotary valve 19 is turned on its axis for that pur ose. '22 designates packing rings for sai rotary valve.

23 designates a s ring-actuated igniter in said rotary valve, t e same being arranged in any vwellknown manner to produce a spark inside the cavityjof the valve at an appropriate time when the port 21 is closed to the supply-pipe 26, and 1s open or about to become open to the channel 3 behind one of the gates 14.

24 is an adjustableblock mounted on the shell 1 and carrying a tripper 25 for the dog 26 of the igniter. v

The valve 19 may able c ontrivance driven bythe rotation of the piston. In the drawings I have shown a cam 27 to which motion is imparted by the shaft 11, and which .cam engages a 'rod 28 y that actuates a crank 29 against the force of spring 30, the tendency of which is to normally hold the valve with its port 21 open to the, channel. f

31 designates an exhaust-port opening from the end ofthe channel 32 is a valve to close said exhaust-port. For the purpose of reversing the engine, the same is provided at"each end of the crescent channel with like gas su ply, ignition and exhaust devices, the

be rotated byv any suitrotate.

.The spring 16 forces the gate outward to be expelled through the exhaust port 31.

connected 'with the levers 33, 33 by connect-.

ing rod 36, and controlled by the grip lever 37. -Said levers are connected with the valves 32, 32, respect1vely, which alternately close and open the exhaust ports, closing one at the sanieloperation that opens the other. Said levers 33 are also connected with latch- rods 38, 38", which are adapted to alternately hold out of commission the crank 29 or 29', as the case may be, of the rotary valve which is to be closed, and also holds said rotary valve closed,v at the saine time allowing the other rotary valve to play freely, and allowing the spring 30 to hold the cam-rod 28 thereof in position to be engaged by the cams 27.

In practical operation, the levers 33 will be the different parts to operate in a manner obvious from inspection of the drawings; that is to say, the cam-27 actin(r on the rod. 28 will move the crank 29, theretby throwing 'thrown into the position indicatedV in the v drawings, when it is 'desired to drive the pisthe valve 19 into position with the port 21 adjacent the port or pipe 20 through which the com ressed gas or other explosive mebe admitted to thevalve. y

As-the piston rotates, the cam 27 passes the crankrod 28, thus allowing the spring 30 to suddenly return the valve 19 into position Where its port 21 will open into the tip of the channel 3. At the same instant, or a moment prior thereto, the igniter will be caused to operate to produce a spark, thereby ig-A niting .the charge, whereupon the expansive -medium produced by the combustion of the gas will enter the tip of the channel 3 just after the gate .14 has passed the port 21 so that the gate receives the impulse of the ex-V pansive force,` thereby causing the piston to fill the-c iannel 3, and as the exhaust port 31 is opened to the atmosphere, the contents of' the gate 14 advances, the lrod 28 and its crank 29 are again operated byfcam 27 to l upon .the operation just described willl be repeated, vand .so on.

.37 lesignates a water-]acket through which vwater is circulated by the valved pipes 39, 39.

40 designates valves to throttle or cut o':

the compressed J"gas supply. The levers 33 are preferably connected by rods 4l with the valves 40 to open the one and closev the other-v valve, and vice versa as the levers are thrown into one or the other positionfor driving or reversing the engine. vided With a-plurality of notches, as 42, .43',

the former being designed toholdtheflatch' that the piston is still .rotating i'n the direction indicated by; the large arrow in Fig. 2,:

the vcontents ofthe channel 3 will be retained insaid channel and will act as'a cushion to retard or prevent the advance of the gate 14. It is evident that the extent to which the-retard ation takes place will depend largely upon the extent to which the exhaust port 3l is closed. the levers 33 may adjust them so as to throttle the exhaust to any extent required, but such throttling only takes place when the gas valves 40 have both been closed, and in any instance, When either of the gas valves 40 is open, the appropriate opposite exhaust-valve willl likewise 'be o )ened to allow free egress of the contents of t ile' channel 3 in advance of 4 4 1s a pet cock to draw oth any accumulation's that may occur in the channel 3.

and designate heads for'the shell removably secured by bolts 47.

The pistonprojects laterally beyond the sid'es of the channel 3 to form seats for a plnrality of spring packing-rings, as shown, in order to make a gas-tight joint.

be-rofsnch rings may be employed as may be Any numfound necessary or advisabl e.

The rings'and? are open, as shown at 43 in Fig. 4, and are compressible into the channels 9 and 10 therefor in the shell so as to allow the piston to Sbe Withdrawnfrom the shell. 'In order to give A access to the rings for contracting the same, each ofthe heads 45, 46, is provided with a`-collai` 49, and the shell is recessed'to allow'said collars tolextend in- Ward'suliciently to -form the outer Walls of the channels 4,'5, respectively.- l

50 designates set-screws in the piston adapted to be screwed in to clamp the gates when the same are compressed intoithe piston by the Wall of the shell oppositeA` the channel' When the .gates have' thus been rclamped in thelpiston 'and vthe rings have' been contracted as stated, then the piston .may be Withdrawn and replaced as desired The segment 35 is pro- The operator having control of :for repairs.' .After replacing the -piston the set-screws'will be loosen ed, ythus to allow 'the gates to freely move in their Ways as thel piston revolves.

. The inletjport 21 at one side and the exhaustport 31 at the other side are spaced apartin one direction about two-thirds, and

cirilmference of the internal chamber of the shell, so' that the time during whichl the charge of hot-gases is held between the two gatesis reduced to the minimum, and the straight, smooth space between said ports f opposite the channel 3 is of maxi-'mum length t'o pack against escape of -theggases in the wrong-direction. l
