GAS-ENGINE Specification of Letters Patent.

latei'ited Mar. 23,1915.

Appiication filed August 24,1314. Serial No. 358,178.

To all whom it may concern Be it known that I, FRANK Guns-Ecru, a subject of the Czar of Russia, residing at Passaic,'in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Gas-lilngines; and I do hereby declare the following to be a full, clear, and exact description of the invention. such as will enable others skilled in 1 the art to which it ap 'mrtains to make and usethe same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

The present invei-ition relates. generally, to improvements in explosive-or internal conilmstion engines; and the invention has reference, more particularly, to a novel construction of rotary explosive (iv internal combustion engine.

The said invention has for its principal object to nfovicle av simple. eliic-ient and econoii'iical rotary. explosive or internal. combustion engine. in nhich a casing:

and a. rotor-element are conihined and constructed in such a novel manner as to provide a plurality of combustion or firingchambers; and l'nrtherniorc each chamber is provided with a gas admission valve and port. an exhaust port, and a gate member, together "with means for properly ope ggaing the same to produce (.XPlOSlxG impulseskuccessively in each of said chambers whereby the rotor-ele1nent is rotated.

A further object of the said invention is to provide a/ novel construction of gatemember \vl'iich is adapted to enter each annula r firing-chamber Oil the engine and thus provide a. head or base against which the explosion of the gas reacts to drive forward the piston-vanes connected with the rotorelement; and, at the smnetime, a novel mechanism is provided for raising said gatemembers out of said chambers so that the said nston-vanes of said rotor-element may pass the same at the end of each rotation of said rotor-element. I i

"A further object of the present invention is to provide novel means for operating the gas ,cei-ssi've explosive impulses vtailed description of 'tion of the arrow cc,

admission valves and the gate-members of each firing-chamber in proner time relation relative to each other and to the rotation of the rotor-element, whereby the suc- W n are obtained and tln ed in the respective firing;chambers.

Other objects of this invention, not at this time more particularly enumerated will he clearly understood froni the following del the present invention. With the various objects of the present ihvention in view, the invention consists primarily, in the novel rotary combnstion ene gine hereinafter forth; and, the inven tion eon ists, 'l'iu'lherniore, in the novel er rangeinen'ts and combinations of the various and parts, ivell as in the details on the which. avili be more fullydescrihed in the 'lollowine specification, and then finally enihoilieil. in the claims which are appended to and which form an essential part of this specification,

The invention clearly illustrated in the accompanying drawings in which Figure l'is side elevation of the novel rotary internal combustion engine made according to and ei-nbodying the principles of my present inventiol'l. Fig. a vertical longitiulinal section of the same taken on line 2-2 in said Fig. 1, looking in the direction of the arrow (1,; 3 is a detail plan view of a portion of the top of the engine;

is a plan elevation of the rotor-element of the enginelrenioved from the casing; and illustrating more particularly the position of the pistoirvanes connected the'ith; and Fi 6 is a transverse section of rotorelement taken on line 6--6 Similar characters oi. refcrcnceareenif. i ployed n all (it the hereniaoove descr bed views to indicate corresponding parts;

istructiono'i the said partsallof said -15,.which leads from a suitable carhurcter or= gasproducing mechanism. Formed. in the interior of said gas port 43, and in connection with saidvalve casing 42, is a valve seat 46 upon which is normally seated a 'valve-member 47 which normally closes the said gas port -13. Connected with said valve member 47'is an outwardly extending valvestemiS which projects outwardly through an opening 49 in said cover-member 3% which also extends over and closes the outer end of said vg ilve casing 462. Said valvemember 47 is ormally retained in closing position or seated upon. its seat 46 by means of a valve-spring 50. Secured upon. the outer surface of said cover-plate 3i is a ful crum frame 51, to the standards of which is pivoted a lever 52 which engages the free .end of said valve-stem 48, said lever haiir'ipg an outwardly extending operating arm which, when properly engaged, oscillates said lever to depress said valve stem thus removing the valve 4? from its seat-46 and opening the valve-port 43 to the passage of gas thercthrou'gh into the firingrhamher a. Said admission valve and its g: 4

port is located on one side of the gate-mem her 33, and located on the other side of said gatemembcr is an exhaushport 5%]; in communication with said .[iring-clninibcr a, and communicating with said exhausoport 54B is an exhaust conduit Located beyond said gas admission valve is a spurioplug 56; which screws into the casing so that its terminals are located. in communication with said firing-chamber a. a

The reference character 57. indicates a vcrtical s1; indlc,the lower end o'l which is jour naled in a bearing opening formed in said face-plate 1.0, and a portion of which is further supported and journalo 'l in a bearinghracket 59 projecting from said housing ill. Also connectci'i with said 'tacc- 'ilatc .10 is a bearing member (30 in which is rotatably mounted. a horizontal spindle (31. Secured upon the inner end of sa d horizontal spindie 61 is a bevel-gear (32, which meshes with and drives a bevel-gear 63 connected with said vhrtical spindle 57. Secured upon the outer end of said horizontal spindle G1 is a sprocket-wheel 64 over which runs a driving-chain G5 twhich is driven by a sprocketwheel (36 secured upon said main shaft- 9. Through the above described transmission mechanism the said vertical spindle 57 is driven or rotated at the same speed as said mainshaft 9. llXQd upon the. upper end of said vertical spindle ,57 and driven thereby 55 isa cam-memberfit', the-same having agateoperating cam-portion 68 and a valve-operating cam-portronSQ. As said cam-member 67 is rotated synchronously with and at the.

some speed as said shaft 9 and rotor-element 13', it is so positioned that, the rotor ele 31 and out oi 'said firing-chamber a said gate-member 33, so that said pistonwane 28 may pass said gate-member. As soon as said p'iston-vane 28 has passed beneath said gate-member. the cain-portion 68 has moved out of engagement with said lift-arm 41 and the springh? again returns said gatemember to normal position within and extending transversely across said firing-chamher a. As the piston-vane 28 continues its forward movement, the cam-portion" 69 en gages with and operates said lower-arm 53 to carry said lever 52 into depressing contact with said valve-sham 451, thus opening said valve 47 to allow anew charge of gas to enter said firing-chamber a between said gtli'lillfillflbhl 33 and sai piston-tans 28. As soon as the piston-vane 28. passes saidsparloplug 56 the ignition system is timed to causc.an i gnition spar]; at the ten n'iinals 01? said sparloplug which explodes the new chin-go oi? gas, the cam-portion 62) having in the meantime passed. out of contact ith said lcv'r-xrl-arm 53 so that the valvespring 50 has closed the valve .47. llnder the impulse of the exploded gas charge, the expansion oi which acts against the gateincniber 33 an impact-or )lO icllin im misc is exerted uponsaid .pistonwane 38 which drives around the rol 1-clcmcut 5 to make another rcrolution which is transmitted to the main-shaft 6), in the meantime the movement of the said piston-vane 25 propels the exhaust or spent gases o he previous explosion through the chamber a and out of the exhaust port 5 the gatc-oncmhor 33 preventing this exhaust from reaching or mixinn with the fresh and subsequently explod cd gas-charge; In this manner the cycles of operation are performed in the cylinder or tiring-ch11Inber a. r

Connected with said .l ace-plate, i0 is a housing containing a gatcancn'ibcr. and gas admissioi'r 'valvcauechanism together. with operating means therefor of the same con struction as alrcat ly above described, so that the same rei'm-encc characters will identify the respectivc.detail. parts of the same. Said face-plate also is provided with an exhaustport and spark-plugalso identified by simi lar reference characters. Thesedevices opcrate. in connection with the firing-chamber meat 5 in the same manner as do their counter-parts described in connection. with. the firing-chamber a and pistonwane 28. A cam-member having gate-operating cam-portion 71 and a valve operating camportion 72 is fixed upon and driven by said main shaft 9 to operate the said gate-memher and gas-admission valve of said firingehamher b. In iike manner connected with saidface-plate 14 is a housing containing a gate-member, and gas admission valvemechanism together with operating means therefor of the same construction as already above described, so that the same reference.

characters will apply to identify the same. Said faceplate 14 is also provided with an exhaust-port and spark-plug also identified by similar reference characters. These devices operate in connection with the-tiringchamber 0 and piston-vane 30 of the rotor element 5 in the same manner as do their counter-parts described in connection with the tiring-chamber (L and pistonane .28. A ca iii-member 73 har'ng a gate-operating camportion 74 and a valve-operating cam-portion 75 is fixed upon the opposite end of said main shaft 9 to operate said gatr-aucmbcr and gas-admission valve of said tiringchamber 1'.

The respective gate-members, gias-admission valves, exhaust. ports and spark-plugs are spaced one-hundred. and twenty degrees apart Whereas the (aim-members c7, 70 and 73, well as the iisimrvanes 2R. 3 and 30 are respectively in aiincuu-ut with each other, or so related as to travel together, consequently the cam-members respectively act upon their respective, gatemembers and Yul\O-lltlliliSHlfiil valves only when they pass them, hence the explosive impulse of the gas charges in the respective firing-chambers, act upon the respective piston-vanes 28, 2'2) and. 30 successively. It therefore follows that there occurs a power impulse upon said rotor-clement at every one-third revolution of the same, or three such impulses per revolution as the successive explosions in each firing chamber 0., b and 0 occur. In view of such arrangement and operation a przurtically eiiicieiit engine is the result which cozuhines in a rotary engine all the advantages of the multiple cylinder type of reciprocating engine in producing a plurality of power impulses per each revolution of the main or drivingshal't.

Of course, it must he understood that I. do not limit myself lo the use oi three firing chambers. since more or less than that umnher may be provided, With gas controlling mechanism spaced and operated to produce successive explosions (herein. in fact by incrcasmg the width of tho rotm-rlcment and easing the number of tiring-chambers may be increased; indefinitely as desired. and a plurality of such tiring-chambers at the cirmesses cum'ference of said rotor-element, may make it desirable to eliminate the side firing chambers. J I

It will therefore be apparent that Whiie the above description and the accompanying:

drawings show a preferred type illustrative oi the principle of construction. I desire to retain. i'. do not wish to limit myself eiitireiy to such form and arrangement thus shown and described. i: am also aware that some changes may he made in the geuerai ar angemciits and combinations of the various devices and parts of the novel rotary iutei nal combustion engiue,.as well as in the do tails of the construction of the said parts, .vithout departing from the scope of the present invention as set forth in the fore going specification, and as defined in the claims which are appended hereto. lience I do not limit my present invention to t" exact arrangements and combinations of if various devices and parts as described in said specification, nor do I confine myseif to the exact details oi. the construction at the said parts as iilostrateci in the acccmpauyinp; drawings.
