DRIVING-BOX MOUNTING.

Application filed August 25 1926. Serial No. 131,452.

The present invention relates to driving I between the driving box and the jawsof the frame pedestal.

The invention also relates to means for taking up lateral play between the wheels and driving box and for providing an improved construction which will assist in securing the pedestal binder to the frame.

Although the invention is intended primarily, for use with locomotive driving boxes, it is also applicable to the wheel and axle construction of engine and. trailing trucks and the like.

The driving box isordinarily positioned between two jawsof a frame pedestal and a binder extends between the jaws below the box which has end flanges disposed on opposite sides of the jaws. Between the driving box and each pedestal jaw. is arranged a.

shoe which has flanges extending on'oppo site sides of the pedestal jaws to prevent lateral movement between the shoes and frame. One of these shoes is usually of wedge formation, or has interposed between the same and the pedestal jaw a wedge ele ment which is vertically adjustable to take up wear.

The flanges on the shoes frequently break off and replacement involves considerable labor since it is necessary to drop the binder. This breakage is frequently due to the side thrust of the engine which develops particularly in taking curves, and defective adjustment of the compensating wedge, which is ordinarily provided with one of the shoes, on to improper vertical adjustment of the shoe itself when it is of wedge formation.

The present invention seeks to provide a shoe construction which will prevent wear upon the frame and which .will include more rugged and durable shoes.

The invention also seeks to provide means for readily taking up excess lateral motion between the locomotive wheel and the driving box. When excess. motion between a locomotive wheel and its driving box develops, it must be immediately reduced within certain limits. Heretofore, it has been necessary, in order to reduce this lateral play, to remove the wheel and axle from the locomotive, which entails considerable expense and delay.

The invention seeks to provide an improved shoe and wedge construction which will facilitate taking up of lateral play and render unnecessary the removal of the wheel and axle.

. Briefly, the invention consists in providing relatively flat shoes instead of the usual shoes which are substantially U-shaped in cross section and have flanges extending on opposite sides of the pedestal jaws. Upon the frame at each pedestal jaw is provided means, preferably in the form of elongated strips, which extend outwardly beyond the face of the jaws and at each side of the shoes, to retain the latter against lateral movement. These strips extend downwardly at the side of each pedestal jaw, between the frame and the driving box flanges and vertical movement of the driving box in the pedestal causes wear only upon the shoes and the strips, which may be readily'replaced. To take up wear one of the shoes may be formed as a wedge or may have positioned behind the same against the pedestal jaw a vertically, adjustable wedge element. "When the vertical strips which retain the shoes in position become worn, they may be readily.

vreplaced and thus there is no need for filling out the frame which is fully protected by I the retaining strips.

Furthermore, the strips are preferably constructed of different thickness from one another so that simply by transposing them it is possible to effect a lateral'adjustment of the driving box, and therebytake up any lateral motion between the wheel hub and the driving box.

The above and other featln'esand objects of the invention will become clearer as the description proceeds in connection with a preferred embodiment shown in the accompanying drawings, wherein V Figure 1 is a partial elevation and partial sectional view on the line 11 of Figure 3.

Figure 2 is a vertical sectional view on the line 22 of Figure'l. v

Figure 3 is a horizontal sectional view on the line 3-3 of Figure 1.

Referring to the drawings for a more detailed description, the invention is shown as applied to the frame of the locomotive having the usual spaced pedestal jaws 10, 11, the latter having an inclined face 11. Between the jawsis positioned a driving box 12 enclosing the axle 13 which carries and driving box as-the latter moves vertically inthe pedestal as will be understood. Each shoe is relatively flat as distinguished from the usual shoe which is substantially U-shaped in. cross section and has flanges fltting opposite sides of the pedestal jaws. In

.lieu of such flanges there is provided retaining means, preferably in the form of elongated strips arranged on opposite sides of each pedestal .jaw and extending beyond the face .of the-jaw toward the driving box.

These strips receive the shoes therebetween and prevent lateralmovement of the shoes.

ltwvill be observed further that they are arranged between the (ilriving box flanges 13 and pedestal jaws so that any wear resulting from vertical movement of the driving box takes placeupon the strips and not upon the frame, the strips being held rigidly on the frame against movement.

For the purpose of securing the strips they may be either bolted tofth'e frame, or, as illustrated in the drawings, extended upwardly and laterally over the top of the frame to provide supporting shoulders 22 and juxtaposed lugs 22 connected by a bolt 23. 1 The strips may be also lengthened downwardly to provide portions 24: adapted to receive a binder supporting element 25 in theform of a wedge which extends through the strip portions 24 and has a threaded terminal 25 receiving a. locking nut 26. This, construction provides an emergency. support for the binder should the retaining bolts break off.

' It will be observed that the outer strips are somewhat thinnerthan the inner.ones,-

which is their relative position when first installed. This arrangement 1s adopted in order to permit of outward adjustment of the driving box toward the wheel when excess lateral motion develops between ,the wheel and driving boxdue to wear upon thewheel hub liner 27 and the driving. box liner 28. By simply removing the strips and transposing the two pairs on opposite sides of the engine the-thicker strips will be placed between the outer flanges of the driving-boxes and the frame, thus throwing the driving boxes ioutwardly a sufficient distance tostake up any play: which may have developed. To remove the strips it is simply necessary to withdraw the bottom wedge 25 and draw them upwardly; This is, of course,

a much simpler and less expensive operation: than the usual one involving dropping of the wheels and axle and replacement of the wheel hub liner and the box liner. lVhen installed, they provide additional supports der portions which overlie the frame.

In the present embodiment of the invention the same is shown as used in connectionwith a shoe 19, which, instead of being itself fori'ned as a vertically movable wedge element to cooperate with the inclined pedestal jaw 11 has positioned between itand the jaw face 11 a vertically adjustable wedge 29. This wedge at its lower end has connected therewith an adjusting bolt 30 extending through the binder, and as'will be understood, is provided for the purpose of maintaining the. shoe closely against the driving box so that only vertical movement of the latter may take place. It will be understood, however, that the invention is applicable to. either this type of wedge con struction or that in. which the shoe and wedge are of integral construction.

The invention has a number. of very marked advantagesover the ordinary construction, wherein. the. shoes are'substantially U-shaped in-cross section) These ad- "antagesf briefly, are

'1; The elimination of shoe breakage which is the cause of considerablerepair work upon locomotives.

2.;The elimination of virtually all wear upon the sides of theframe pedestal jaws, since the strips cannot movenwith the shoes should any vertical movement of these take placedue to 'defective adjustment of the wedge.

3. Facilitates taking up of excess. lateral motion between the wheel and driving box byeliminating the necessity. for dropping the entirewheel and axle; and

4. Provides an additional supportfor the binder to take the place of the securing bolts should the latterbrealr ofl.
