Patent N o. `1,479,918,`on, almulticylinder A general objectfof theninvention in so 'fair as this divisional application is conn. cernedis to provide in an-engineof'the type outlined a simple organiza-tion ofparts 1n whichL ther mvable'elements.. will. be ellif l ciently lubricated.
I'. Another Aobject of the invention andstill featuring simplicity of parts is to provide y for lubricating the movable parts effectively and' continuously with theutilization of the purpose and the adaption; as far as'possible,
of parts structurally necessary in the engine for /the 4additional function of providing parts ofthe lubricating system. l
, l Broadly, this latter object is attained 'by -allyof the driven shaft through one construction. A Varlous other ob]ects must necessarily Ibe V'made of relatively, solid and advantages of the invention will be in -pat obvious fromm I tion, and the invention alsoconsists in cer-l tain new and novel'features of construction and. combination Y cfa parts hereinafter -set forth and claimed. y

A ormed, inelfect, of three long, circular walls disposed cncentrically The .casting is about the axis fa-b and including anvinner wall 14, anV intermediate wall 15,' andan .outer1 wall 16. The space between the intermediate wall and the outer Wall -is divided longitudinal] physiln-thevfollowing C'description and in the claims, parts will identified by `specific ynames for convenience' of expression' butl they are intended tobe as genericin their ofthe axis --b to, -form a plurality of ongitudinally extend? csf Inj'the accompanying drawings, there ing explosive ychambers 17 disposed inja circle about the axis a--b and each having a relatively small cross-sectional area perpendicular tO the axis. The space between the intermediate wall 15 and the inner Wall 14 is divided by means of'a radial partitiori'j l 18 to form two annular gas conducting passageways 19 and 20. `The passageway 19 35 thereto.
ried inthe outer end of a centrallydisposedI `shell 65.
'As is usual with such engines the axially disposed shaft 26 is formed symmetrically wit l ya straight centralv portion. 63, aligned end portions 67"and 68'concentric with reference tot the .axis w-b and with two inclined portions C69 and l70 extending at the same angle andv in opposite directions to each other Lacross the axisa-b andconnectiiig' re'- spectively thel ends .of the` straight portion 63 with en portions 67 and 68 as is' usual `in such ty es ofwabbling plate transmisf sion devices. The.l shaft parts are connected by means of a pair of coating face plates one ofl which is Athe face plate 71 formed integrally with and disposed at an angle to the respective inclined ortions169 or' 70; of
l the `shaft. .The other ace lfate 72 consti plug 81 one end of the-tube is connected with the drilling 86. The outer end of each tube is connected with asupply intake passageway 89 drilled in the otherwise solid shaft end and in. the'plug 80. This passageway 89 is designed to receive lubricant from a source of supply such as the oil pump 91.
.The tube 87 is provided with outlet vents 93 to permit the passage .of the lubricant into' the hollow portion of the crankfpin. The crank pin is provided with outlet ports` 94 for supplying the bearings 95 and 96 of the wabble plate construction..
The central portion 63 of the shaft is provided adjacent opposite ends with inset 8o .plugs 99 which constitute supports for oppov i site ends of an oil 'conducting tube 100V axially disposed in the central portion of 1 the shaft and'extendin substantially for its entirelengthg' rThis tu e is of advanta e in tending to reducethe amountof .lubrlc'ant necessary when shafts having large xtubular -cayacity'are utilized. f f' he shank/vv portions at opposite' ends of the inclined crank-pins are enlarged to ex-l tendfoutwardl lbeyond the outlines of the .periphery of t e pinto' form abutments 101 atV oppositeends thereof..- A hollow," rela: ftively li ht. wabble plateconstruction of readlly emountable and .intertting parts is fitted between the abutments. 101 so as to tutes a flange from one en of a Sleeve 73. beheld against end play. This' construction includes two fnusto-conicalshells'102 and j 'which is slid fon the 'adjacent end ,of the straight portion 63 of the shaft and is held y The' parts forming the'shaft are m e hollow to accommodate the lubricating. ature ofthe invetioniand are made massive withrelatively thick walls so as to transmit the heavy strains imposed thereon .and atthe Sametime maintain their `true symmetrical osition with referenceto the axis'ab un er prolonged and severe work- 4in lconditions. rlhe central portion 63 is' rovided at opposite ends with closlng plugs .45 8 and'thus forms-aclosed lubricating reser'. vo1r/79 within the'lengthl ofthis 'straightportion in the ,embodimei1t of .disclosed in the figure.
the invention The inclined portions or crank of the ki0` shaft are likewlseformedof a hollow tubu v lar/structure and are closed at opposite ends bymeansof'plugs80 and '81, thus providing oil reservoirs `82 in each .of 'the inclined v'crank pin portimons of the shaft. ,Commu- A nicationis provided between the-lubricating reservoir and `the"reservfoins 82.y at opposite ends-thereof by means of drillings, one ofI which. 86 extends angularly from the reservoir 79, through the side of the` shaft 63, through `the sleeve 73, and .face plate"71.
-A lubricant conducting tube 87 lis positioned axially in the respective shaft portion 69 or 70, and has its opposite ends inserted inthe closing plugs and- 81^at opposite ends 65 ther-'cof and by means of a drilling 88 in the 103 with .their small ends projecting outwardly from each otherl and formed into -relatively long -hubs 104 engagingl the abutments ,and with their hollow sides 4facing Aeach other and spaced apart. The bearings and 96 are formed between the hubs and the ,portions of the.l pin encircled thereby. By this constructipn' 1t is possible to mount the wabble plate shells only at the ends of `free of frictional resistance'and permitting thev mountingof: an end Athrust bearing 105 inl the lubricant containing Aspace'106. The lubricant containing space enclosed by the shells is encircled by a relatively thick thrust ,.Ithe crank pin, leaving the intermediate part ion i lshells. 102 and-103. The spaceenclosed by the shells 102, 103 and the wall I108 forms the lubricant containing reservoir 106 which is' fed 'from -the ports 94 leading from the in'- terior of the pin and the piston rod bearings. It will be noted that the end thrust beariglO is positioned within the lubricant containingy reservoirand this construction is ofwmaterial importancefwhen. it is 'considered that the "thrust of the pistons on the shaft.A is usually transmitted through the .wabble plate with a decided tendency to distort the plate an'd'thus destroy the effective@ ness ofthe pre-designed organization. The ring 107 exteriorly of the wall 108 is formed of. outwardly extending shell walls 118, which are inclined towards each other and at the jointure of the walls is provided with a circle of spherical sockets 119 one for receiving each of the spherical heads 120 of the longitudinally` disposed piston rods 121. Lubricantconducting tubes 122 extend from the wall 108 through the hollow space between the shell walls 118 and open into the sockets 119 to supply lubricant from the reservoir 106 to the several .piston end sockets. The pistons 124 are of the conventional trunk type, are reciprocatorily mounted in the piston cylinders 45 and are demountably connected by means of the4 spherical sockets 125 with the inner ends of the piston rods 121 as is usual in such constructions. It will be appreciated that the lubricant leaking from the exposed front end of the sockets 119 will be splashed by the rocking wabble plate into the open ends of the piston cylinders to lubricate the same as well as the sockets at the piston ends of the piston rods. The wabble plate will also act to splash this leaking lubricant into the adjacent shaft bearings.
There is provided an attachment which includes the lubricant supplying pump 91 which discharges through the tubes 144 into the drilled conduits in the ends of the shaft. The pump is supplied from the bottom of the end shells through a return pipe 145.
In providing for the lubricatmg system every effort has been made to reduce the amount of lubricant carried and parts which were found necessary in addition to the power transmission parts have been made as light as possible. In general the invention features a refinement in structural organization of an engine of the type disclosed rather than in any improvement in functional operation.
While we have shown and described, and have pointed out in the annexed claims, certain novel features of our invention, it will be understood that various substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
