Be it known that I,

FRANK L: Sessions, a citizen of the United States, residing at C0- lumbus, in the county of Franklin and State of Ohio, have invented certain new and use-' ful Improvements in Car-Axle Boxes, of

which the following is a'specification, refer ence being had therein to drawing.

This invention relates to improvements in the boxes in which are mounted'the' axles; of cars, it pertaining more particularly to the axle mountings of electric locomotive cars such'as are now largely used in mines and other places. I

The object of the invention-is to provide the accompanying a box or mounting and to so 'constructthe adjacent parts of the vehicle body that/the box can be readily removed endwise of the axle without requiring-the taking down-of b any of the heavier parts of the vehicle; and.

also relates to the combinationwith a box so removable of wearing plates which can be attached or detached as occasion requires.

In the drawings, Figure 1 is a side view .of an electric locomotive having its axle oxcs and adjacent parts constructed and re' lated according to my improvements; Fig. 2 is a/vi'ew partly in end elevation and partly in section of the same. Fig. 3 is a rear or inner view of the axle box. Fig. 4 is a side elevation of the box. Fig. 5 is a plan view of the box detached. tFlgS. 6 to 9 are details.

In the drawings the car body is shown at 1; The vehicle is of the class of electric locomotives such as are used in mines for haulage purposes and also used in other places. This body is formed of cast iron havingtwo side walls or parts 2' and connecting end parts 3. As shown, it is mounted upon two axles 4, to which are rigidly secured the trackwheels 4'.

At 5, 5 there are recesses in each of the side pieces 2, in which recesses are situated, the ends of the'axles and the boxeswhich support'them. Each box is indicated as a whole by 6, it having the side walls 7 and ()n the side walls there are guide ribs 10.

The side piece 2 of the vehicle. body is castwith a recess at 11 in the side edges or wall of the opening 5. At the inner edge of this there is aniuwardly projecting flange or wall piece 12, preferably cast integral tical side flanges 16. "Each which he plate is situated between with the metal of the surrounding part of the body. a

{At 13 there is a rabbet on each side of each opening 5. a

The guide ribs cesses or chambers at 11. They are allowed to move vertically therein, their vertical length being less than that of the recess.

movements of the box and the vehicle body, the one relatively to the other, I combine with the box bushings or wearing plates l4, eachof these having a back plate 15 and of these bushings or wearing plates 'fits' snugly in the recess or chamber -l1 and in turn receives snugly one of the guide ribs '10.

17 indicates a wearin block which is fitted in theupper art- 0 the chamber in the ox 6 proper. It as a concave surface at 18 fits against and bears upon the axle. It is detachable-and when worn it can be withdrawn and another substituted. It is 10 of'the box in the re- Inasmuchas there is wear caused by the ver- I held in place by means of the holding bar 19 which is secured in position by the screws 20. The front part of the box closed by the door-or cover piece 21, the latter having hinge cars 22 which are pivoted to the car 23 projecting from 'theupper part of the front wall of the box. The door or cover piece is held firmly in the closed position by means of the spring 24 bolted at 25 to the front face of the door and having its upper end 26 arranged to bear against the car 23.

27 is a car spring interposed between the box (5 and the top wall or edge of the opening 5. V v

On the rear side of the box there is a plate 28 detachably secured by means of pins or bolts 29.passing through lugs 30 on the plate and through an car 31 at the it'll) of the box and an ear at the bottom.

This plate 28 has a vertically elongated aperture 33 through which passes the axle.

track wheel 4' and the inner face of the box; consequently it takes all of the wear caused by the friction of the rotating wheel hub. After an' appreciable amount of wear has taken place there is a troublesome play of the vehicle body longitudinally of the body. This I obviate by removing the wearing plate or washer plate which has become worn and substituting anew one.

the hub of the flanges 12. By the removing of'the bars 34 from in front of either; box the latter is.

freed for removal longitudinally of ,the axle'. as are also the bushings or wearing plates 14. f

The advantages incident to the construction and arrangement of the devices which I haveshown will be readily understood. If at any time it is found necessary to'withdraw an axle box it is not necessary to ele-.

' vate the whole vehicle bbdvto a posit-ion which will be above the horizontal plane of the axles, as has been heretofore required, in

order to allow the boxes to be removed atthe bottor'nof'the opening 5. With my construction any boxcan be quicklyremoved by supporting the vehicle body upon one or two small- ]3.0ks, causing themto exert slight lifting action upon it so as to relievethe boxes and s rings of the weight. After the" jaek or .jac have been put in position the bars 34 are removed and thereafter the box and also the bushings or 'wearing plates 14 can bewithdr'awn longitudinally from the. end of the axle. If the wearing plates 14 are worn new ones can' be substituted. If the spring should'be broken another 'canbev applied. If the wear of the wheel hub ontlie. inner face piece 28 has become undesirably great the latter can be removed and another of suitable thickness can be substituted; after any of which the box can be quickly restored to its position on the axle, together with its guide bushings 14, and all the parts fastened in place by again securing the face bars 34.-

The guide ribs 10 have their bearing edges shaped so as to taper upward from the central part 36 and also so as to taper downward therefrom as shown at 37. The result being that avertical oscillation of the box is made possible around the central parts of the rib. f

' What I clalm is:

1. In a vehicle of the sort described the combination with the body having the opening 5 in the side thereof and havmg at each edge of the opening the chamber or recess with an inner wall and a removable outer wall, of the box movable on and oil from the end of the axle, and having the laterally projecting guides fitted in the said recesses 1 at the edges of the opening; the car spring interposed between the box and the upper edge wall of the opening, substantially as set forth. 1
