"GEAR/ED LOGOMOTIVE.
T 0 all whom it may concern V Be it known that I, ELMER Ff. :Bnoxnn, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented new and useful Improvements in Geared Locomotives, Of
which the following is a full, clear, and exact description. 7
My invention relates to geared loo0n10-.
tives, and particularly. to .the means for supporting the crank-shaft thereof.
One of the difiiculties, which builders ofv this type of locomotives ha've 1'sou'ght to overcome isto obtain a perfect geared connection between the crank-shaft and driving-axle of the locomotive. This class of side to side, and this see-saw' movement,
together with the up and down movement of the bearings thereof-and tlie' jendthrust of the axle, has madeit necessary to devise some means for keeping the axes of the gears substantiallyfparallel and for avoid-" ing theexcessive wear and strain that would otherwise result. f Heretofore efforts have been made tov overcome this difliculty' by means of peouliar combinations and constructions of said gears. Q I
this difficulty by means that will always maintain the driving-axle and cra nk-shaft in their relative "parallel positions, while permitting the driving-axle-to-accommodate itself to the'rocking movement caused by its f wheels traveling over uneven tracks. This I accomplish by the means hereinafter fully described, and as in the claims, v

Fig. 4 is a longitudinal section of a fragment of the supporting-frame, taken on dotted line 4, 4, Fig. 1.
.My invention, broadly speaking, comprises means for suspending the elements that support the crankshaft of'a geared locomotlvefat three points; two of which polnts being located on the axle of the drivewheeland one on the underframe of the locomotive midway between the longitudinal side-sills thereof. By suspending the crank-shaft in this manner said crank-shaft Wlll always remain parallel to the axis of the drive-wheels. The principal elements embodied in my improvements are a thre'e-point-frame and a, gear-housing, which will hereinafter be more fully described.
The three-point-frame referred to consists of a V-shaped frame or structurethe apex of which is formed into a ball. 10, that is swiveled between anupper and a lower transversely disposed horizontal plate, 11 and 12 respectively, located midwa between the longitudinalside- sills 13, 13, of
the underfra-me or supporting frame of the locomotive. The lower plate rests upon a cross-bar or transom: connecting these side sills, and the legs 14,- -14, of the V-shaped frame or structure merge into the inwardly 15, 15, substantially as shown, and have corresponding parallel extensions 16, 16, extendv ing beyond said-bearings. A crank-shaft The object of myinvention is'to avoid 17, is journaled in said bearings, 15, 15, and the axle, 18, of the drive-wheels, 19, is journaled in bearings, 20. 20, substantially as shown, made integral with the rear ends of the extensions, 16, 16, substantially as shown in the drawings. These extensions, 16, therefore, extend from a suitable point in front of the crank-shaft to a suitable point atthe rear of the drive a-xle, and are inserted between and have their ends so formed as to engage thejaws 21 and 22 of a longitudinally elongated pedestal made in the side- sills 13, 13. The mouths of these pedestals are closed by the tie-bars 23, and the extensions 16, 16, are capable of a limited vertical play in said pedestals, and in addition permit of a limited lateral rocking movement, resulting form the condition arising from the travel of the Wheels, 19, 19, over the tracks.
The axle and the crank-shaft are connect ed, preferably at their oent'ersof length, by a large gear 24 on the axle, and a small gear 25 on the crank-shaft, and these gears are inclosed by a housing 26 consisting of an upper and lower corresponding section, the meeting edges oil which. latter; are: flanged outward and bolted or otherwise secured to gether. This housing has bearings 27' and 28 for thecrank-shait amhaxle-respectively, that are made one half? in the upper section and the-other half. in the-lower section, and
the axle has collars or flanges 29, 29, that bear against the outer ends of the-bearings 28, to prevent lateral movement ofithehousing;
The ends of the crankshaft extend asuitable distance beyond the-bearings 1'5, 1'5; andare provided" With: cranks 30; i the wrist pins oi? which are connected by suit'ableconnectingrods- (not: shown) to-the piston (not shown): of the engine. The drive wheelis may be situated outside ofthe side sills of the underframe ofthe locomotive; as-showir in Fig. l of the drawings, or thewvheels may be mounted on: the axle inside of said sidesilIauas-shownin Fig; 3 of the drawings;
My improvements permit the. perfectdom' of movement of the bearingelements of the axle of the drive-Wheels,- and insures a corresponding movement of the crankshaft and? the malntenance of theparallelismof? and the distance" betweenthe axes of shaft that imparts its motion to saidaxle;
and means in which said crank-shaftis jour naled that are" pivotally, mounted at oneiend on said axle; and pivotally supported at a: singlepoint' at its opposite end, said crankshaft being j ournaled'r in said? means and retained thereby in constant parallelism:
