GEAREDZLOCOMOTIVE.

Specification of Letters Patent. Patented NOV. 30, 1920.

Application filed June 21, 1920. Serial No; 390,530.

T 0 all whom it may-0011067 21.

Be it known that I, Emrnn F. BAGKER, a citizen of the United States, residing atDavenport, in the county of Scott and State of Iowa, have invented new and useful 1m provements in Geared Locomotives, ofwlnch the following is a full, clear, and exact de scrlption. p

My invention relates to geared locomotives and particularly to the type referred to in mypending application for Letters Patent of the United States filed September 22, 1919, Serial No. 325,347.

The object of my invention is to provide a three point support forthe crank-shaft of such a locomotive that will always insure the axis of the same and of the axle of the drive-shaft remaining in perfect parallelism so that the gears connecting them will always he in perfect mesh, substantially as hereinafter described and as'illustrated in.

the drawings, in which Figure 1 is a plan view of a broken away portion of the supporting-frame of a loco motive showing my improvements applied.

.the hearings in the pedestals of said frame for the axle 7 of the , drivewheels 8, 8. These bearings and the pedestals of theside-frames inwhich they are mounted are the same as those now in extensive use and a detailed description thereof is deemed unnecessary.

At its center of length axle 7 has a broad faced gear 9 securely mounted thereon and this gear is engaged by a pinion 10 of corresponding breadth that is securely mounted upon a transverse crank-shaft. 12, whose axis must always be parallel to the axis of the axle. In order to accomplish this result a housing consisting of an upper and lower section, 13, and lhis provided for said gears which is placed between the sides of the supporting-frame. These sections preferably correspond in construction and design and have their longitudinal edges 15 flanged and secured together by bolts and nuts 16, or

other suitable means. In vertical longitudinal section the housing is, preferably, pearshaped, and the larger end incloses the large gear on the axle 7 and the smaller end incloses the pinion on the crank-shaft. This housing has bearings, that are made half in the longitudinal edge of its upper section and half in the opposing edge of its lower section, for the axle to pass through, and has bearings in the sides of its smaller end in which the crank-shaft is journaled.

. lt'will be observed that the drive-shaft supports the larger end of the housing whereas the smaller end supports the crank-shaft. The ends of the crank-shaft pass out through guide blocks 17 that are supported and have a vertically sliding movement in suitable openings or pedestals in the supporting frame, and the vertical edges of said blocks are grooved and the edges of the pedestals entersaid grooves and retain the block in position.

The smaller end of the housing is, preferably, made slightly wider than the rear portion and each section has a corresponding V-shaped frame consisting of converging arms 20, 20, that project from each corner of said end and meet a suitable distance from V the housing at a point in alinement with the center of width of the latter and mer e into I n a b se1n1spherical members 21, 21, which, when the sections of the housing are secured together. form a spherical journal or hearing ball. If desired, the V-shaped frames can be reinforced by vertical struts 22 22 that are made integral with the adjacent ends of the upper and lower sections and extend in alinement with the center of the width of the housing to the crotch of said arms 20, 20,

The spherical journal. above referred to is ournaled between an upper and lower transverse cross-bar, 23 and 24, the opposing surfaces of which, where they areengaged by said semi-spherical bearing, are concaved sufficiently to retain and support the adjacent end of the housing, and to permit the rear end of said housing to move up and down synchronously with either or both. of the drive-wheels, and at the same time carry and maintain the crank-shaft absolutely parallel with the drive-axle at all times.

It is evident that the improvements hereinbefore described can be used in conjunction with geared locomotives of various designs. I do not, therefore, desire to be confined to the specific construction of the parts of my invention as hereinbefore described of any locomotive to which said improve v, H g

axle of the drive-wheels ournaled in said vious that they may be changed to meet the I requirements of the changes'in the design ments might be applied without departing from the principle of my invention. v

What I claim as new is: i "1 '1. In a geared locomotive the combination with a locomotive supportingsframe, and

the axle of the drive-wheels thereof journaled in the side members of said frame,.of

V a transverse crank-shaft which imparts its motion to said axle, gears connecting said axle and crank-shaft, and means. journaled at one, point at one end and at two points on the axle that retains said crank-shaft in constant parallelism with said axle.

2. In a geared locomotive the combination with a locomotive supporting-frame, the axle of the drive-wheel thereof, journaled in the side members of the same, of a trans-.

,verse crankshaft which imparts its motion to said axle, gears'connecting said axle and shaft, a gear housing therefor one end of ,which is .;pi otally mounted upon saidaxle and which has, hearings in its other end through which said crank-shaft extends, means provided with bearings for sald crank-shaft the end of which farthest from said axle has a'single journaling member, and a single bearing therefor supported midway between the side members of said supporting-frame.

In a geared locomotive the combination with-a locomotivesupporting-frame and the axle of the drive-wheel thereof ournaled in the side members of the supporting-frame,

of a transverse crank-shaft which imparts its motion to said axle, a gear housing one end of which is pivotally mounted at two points upon said axle and has bearings in its other end for said crank-shaft, a swiveled journaling device for supporting the oppositeend of-the said gear housing, and a H bearing therefor supported midway between the side members of said supportingframe.

a. In a geared locomotive the combination with the locomotive supporting-frame, and

the axle of the drive-wheels thereof, journaled in the side members of said support- 1ng-frame, of a crank-shaft, gearing mounted'on and connecting said shaft and axle,

a housing inclosing said gearing and pivotally mounted at one end on said axle at two points, and a universal omtconneetmg the supporting-frame, of a floating transverse crank-shaft, gears connecting the same to said axle, @journaled in said supportingframe, ahousing' for said gears, a substantially il-shaped' member the ends of which are connected to the end of the housing farthest from the axle, and a ball attachedto 7 the vertex of said member, and a bearing thereforin a cross-member of sald frame "thatis adapted to permit said crank-shaft to'moveparallel with said axle at all times.

In a geared locomotive the comblnation with the isupp'ortingsframe thereof, and the axle of the drive-wheels journaled in the supporting-frame, of a floatingl -transverse crank-shaft, gears connecting the'same tosaid axle, a housing for said gears which is mounted on said axle and has hearings in its sides in which the crank shaft' is journaled, a substantially V-sha'pedmember the ends'of which are connected to the end of the housing farthest from said axle, a ball made integral with-the vertex of said /member, and a stationary bearing made integral with said supporting-frame in-which said ball is journaled.

7. In a geared locomotive the combination with the supporting-frame ther'eof,and the axle" of the dri-veswheels the journals of which have bearings in the supportingme, of a floatingltransverse crankshaft,

gears connecting the same to said axle, a

housing for said gearszconsisting of anvupper and lower section one end of which is mounted on said axle and which has openings in itssidesthroughfwhilch the crank- V shaft passes a substantially V-shaped member supporting the end farthest, from the axle, a ball made mtegral with the vertex of said membenand a statlonary bearing made integral with E-said supporting-frame' in c which said ball is journaled.

In witness whereof, I. have hereunto set my hand and seal this1 5th day of June,-
