Specification of Letters Patent.

Patented July 14, 1908.

To all 'whom it may concern:

Be it known that we, GEORGE L. WALL, residing at 1103 l West High street, Lima, county of Allen, and State of Ohio, and LEWIS E. FEIGHTNER, residing at 715 South Broadway, Lima, county of Allen, and State of Ohio, both citizens of the United States, have invented certain new and useful Improvements in Locomotives, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

` The object of this invention is to furnish a means of wholly supporting a locomotive frame upon more than two pivoted trucks, so as to distributethe weight upon a large number of journals, and thus permit a locomotive of great weight to be sustained wholly upon truck-wheels which can follow a curved track independently.

In the present invention, swing-bolsters i are pivoted beneath the two ends of the locomotive frame, and the ends of both swingbolsters are supported upon separate trucks.

By thisv invention, four pivoted trucks can be used, two under each end of the locomotive frame, the center of the swing-holsters at each end of the locomotive being pivoted beneath a body-bolster connecting the sideframes of the locomotive. Only two swingbolsters are required, and the whole locomotive is thus supported upon two centerplates; which leaves all vthe trucks free to turn in any degree required by the curvature of the track, and enables each of the truckwheels to follow the track independently. The ilanges of the wheels may therefore be iitted properly to the rails, and may operate most effectively in guiding the locomotive,

which is of especial importance in a structure having a long wheel-base.

It is readily seen in the drawing, that the truck-bolsters are divergent from one another, as is necessary in turning curves; which is effected by a free connection with the ends of the swing-bolster.

The body-bolster is rovided with a center-plate to rest upon t e swing-bolster; and

each swing-bolster has center-plates under its vopposite ends to rest u on the truckbolsters; and all of the trucs are thus enabled to turn independently, and their wheels are enabled to follow the track-rails in turning curves. A locomotive having the -called Shay locomotive, in which vertical engines at the side of the boiler fireboX are used to propel a horizontal crank-shaft, and such crank-shaft connected by universal joints and slip-couplings with all the wheels in the different trucks. All of the truckwheels may thus operate as drivers, and all of the driving-wheels be furnished with flanges to hold them in place on the rails.

The trucks are shown herein provided with two axles and four wheels each, thus su porting the locomotive u. on sixteen wheelis); but more axles and whee s may be used in each truck, if desired. i

In the annexed drawing, Figure 1 is a side elevation of a locomotive provided with the improvements; Fig. 2 is a plan of the four trucks with the swing-holsters resting thereon,` and the crank-shaft with its connections to the truck-wheels. The locomotive frames are also indicated by dotted lines. Fig. 3 is a plan of the swing-bolster; Fi 4 a side view of the same; Fig. 5 a vertica section of the bolster through the central ivot-plate; Fig. 6 a vertical section ofthe bolter on line 6 6 in Fig. 3, through one of the end centerlates; Fig. '7v is a side view of the bodybolster with cross section of the swing-bolster beneath the same; Fig. 8 shows the under side of the bod -bolster; and Fig. 9 is a plan of the truck-bo ster and end frame. ct designates the left hand locomotive frame, and l) the right hand frame connected by cross-ties c and by the body-bolsters d which-have center-plates e to rest upon the pivot-plates f of the swing-bolsters. The swing-bolsters are shown in Figs. 3 to 6 inclusive, made with two parallel side girders g between the ends of which center-plates h are also secured to engage the pivot-plates upon the truck-bolsters i.

The swing-bolster is shown at the middle with a pivot-plate f having its circular face resented upwardly to support the bodyolster d by its center-plate e, and the swingbolster i's furnished at the opposite sides of such pivot-'plate with bearing-plates or brackets k having sockets formed upon the contact with segmental seats m upon the yunder side of the body-bolster.

The bearing-blocks furnish a means of using harder metal for the wearing face and to compensate for wear as the blocks may be readily renewed when worn, and the sockets are formed simply as a shallow recess with a marginal ange 7c to hold the bearing-blocks in place. The ends of the swing-bolster at the o posite sides of the end center-plates h are a so furnished with brackets n having bearing-plates o with their faces presented downwardly to rest upon bearing-blocks q seated in sockets r upon the top of the truckbolsters i at the opposite sides of its pivotplate. It will be noticed that the pivotplate f and brackets lc at the center of the swing-bolster face upwardly, while the center-plates 7L and the faces 0 upon its adjacent brackets project in a reverse direction.

The details of the truck construction are omitted in the drawing, as they form no part of the present invention, but they are each shown carrying two axles s, and the wheel at one end of each axle provided with a bevelgear t. The rebox of the steam boiler m swings between the frames, at the middle of their length, and four engine cylinders u are shown upon the side of the iirebox in Fig. l, with a crank-shaft e, having four cranks w journaled in bearings w/ which are supported upon the locomotive frame l).

The truck-wheels are all shown ianged to tit the track-rails y of Figs. 1 and 2, and each of the trucks is shown constructed, as is common in Shay locomotives, with bearings carrying a driving-shaft :c having pinions t meshing with the bevel-gears t upon the wheels of such truck. The ends of these driving-shafts and the opposite ends of the crank-shaft e are shown provided with universal joints u which arev connected by slipcouplings e', thus connecting the crankshafts with all of' the axles in the four trucks, and at the same time ermitting each truck to assume an indepen( ent position upon the track-rails y which are shown in Fig. l.

The locomotive frames are shown in Fig. l provided with a water-tank z and a coalunker .e/ at the rear of the iirebox, and as the entire frame is carried by the swing-bolsters upon which the body-bolsters d are pivoted, the whole weight is carried by the pivot-trucks, and all of the wheels which carry such weight may be utilized as drivingwheels by connecting them with the motive power, as shown in the drawing.

The center-plates e upon the body-bolsters d are shown in Fig. l set much nearer to the .frame b than the frame a, as the frame I) carries the engine, whose weight is balanced by thus arranging the center-plates d.

The essential feature of the invention is the supporting of the locomotive frames with the motor upon swing-bolsters pivoted under its opposite ends, each swing-bolster also having center-plates under its opposite ends and trucks supporting such end eenter-plates with wheels journaled in said trucks, and a part at least of said wheels having connections with a motor to drive the locomotive.

The construction is especially adapted, as stated above, for use in a Shay locomotive, in which all the supporting wheels are utilized as driving-wheels by a ilexible gear connection with a motor-shaft, thus permitting all the wheels to be iianged and all the trucks to turn independently in passing over curves. It is not, however, essential to the present invention that all of the supporting wheels should be connected with the motor, as a art of the wheels may be used as trailing or eading wheels, if desired.

The supporting of the entire weight upon swing-bolsters and pivoted trucks is equally a plicable to a locomotive employing an electric motor, a gas motor, or any other niotor agent.
