v RAILROAD-CAR raver,

Application filed June 20, 1925. Serial No. 38,893.

The principal object of this invention is to provide-anovel and improved railroad car truck having means embodied therein for the ready removal and insertion of the wheels in the truck frame. ith the present types of trucks in use both of these operations are attended with great difficulty due to the necessity for removing bolts or other fastening means, or due to the special construction of the frame.

More specifically my invention resides in a frame so constructed that'when it is jacked up a comparatively small distance the journal box may be slid out of the frame lengthwise of the axle, and the wheels may be rolled along the track and thus disconnected from the frame.

Further objects reside in the arrangement of parts shown in the accompanying drawings and will become evident as the description progresses.

In the drawings 1 is a View in elevation showing a portion of a side frame of a truck constructed according to my invention, the view being taken on the line 11 of Fig. 2.

Fig. 2 is a section on the line 2-2 of Fig. 1.

Referring to the drawings the numeral 1 designates a portion of a side frame terminating in a bearing 2, within which is received a journal box 3. This journal box is formed with a transverse rib 4 normally disposed back of the top leg 5 of the frame and with a rib 6 extending on the sides and top in front of the frame.

The top leg 5 extends beyond the bearing 2 and downwardly to a point 7, this downwardly extending portion being sufficientto prevent movement of the journal box in the bearing lengthwise of the frame. Side frames are weakest in the portion designated 8 and by my construction it is possible to make the frame of additional depth at this point and thereby strengthen it. Extend ing beneath the journal box is a lowerleg 9 which curves upwardly at its end to the point 10 spaced from the end 7 of the top leg a distance sufficient to permit passage therebetween of the axlell of the wheel 12.

The journal box is normally in the position shown in the drawings and when it becomes necessary to remove the box or wheels or both to make repairs, the frame is jacked up in the usual manner until the bearing 2 is clear of the journal box, a sufficient space 13 being provided between the bottom ofthe box and the leg/9 for that purpose.- .The space -l'3' is' greaterthan the height of the ribs 4 and 6 on top of the box and therefore after the frame is jacked up the box may he slid out of the frame lengthwise 0f the axle. The opening between the ends 7 and 10 is so disposed that after the journal box is removed the axle 11 will be in substantial alignment therewith and then the wheels may be rolled out of the frame through this openin I From the above it will be evident that I have provided a novel and improved railroad car truck which will permit ready removal therefrom and placing therein of a pair of wheels, without any of the disadvantages present in known constructions and which are well known. It will be seen that no fastening means Whatever are required to retain the ournal box in the frame and that all that is necessary for removal is to jack up the frame and then the journal box may be readily removed. The jack is practically the only tool required, as there are no fastening means to be removed and after the frame is raised both the journal box and axle are in position to be moved out of engagement with the frame in a straight line.

I am aware that changes in the form, construction and arrangement of parts may be made without departing from the spirit' and without sacrificing the advantages of the lnvention and I reserve the right to make all such changes as fairly fall within.

the scope of the following claims 1. A railroad car truck comprising a frame, a journal box in said frame, an axle supporting said journal box, means on said frame and on said box engaging each other and preventing movement of said box lengthwise of said axle, said means being disengaged by raising said frame, and an opening in said frame through which said axle may pass after raising of said frame and removal of said box.

2. A railroad car truck comprising a frame having a bearing, a journal box contacting with said bearing to support said frame, a wheel axle in said journal box, said frame having a top leg extending being spaced apart a distance sufficient to permit- .the passage of said axle therebetop of said box and normally engaging tween.

A railroad car truck comprising a frame having upper and lower legs, a journal box disposed between said legs, ribs on top of said box and normally engaging the front and back of said upper leg, the

distance between said upper and lower legs being such that there is normally a space between the bottom of said box and said lower leg greater than the height of said ribs, for the purpose set forth.

4. A railroad car truck comprising a frame havingupper and lower legs, a journal box disposed between said legs, rlbs on the front and back of said upper leg, the distance between said upperand lower legs being such that there is normally a space between the bottom of said box and said lower leg greater than the height of said ribs, the ends of said legs extending t0- ward each other on one side of said box and spacedapart a distance a, sufficient for the passage of a wheel'axle the-rebetween, for the purpose set forth.
