Similar letters of reference indicate like The nature of my invention consists in providing-the opening at the outer end of a railway axle journal-box with a coveror cap that may be readily opened for the purpose of inspecting the contents of the box and adjusting and removing'the same, and at the same time preventing the admissionof dnst, dirt, and

otherforeignsubstances into'the box.

I construct my nxle-boxin any of the known forms, and to its outer orfront end I attach a cover or cap, A, as shown in Figs. 1, 2, and 3. .At each side of-the axle-box thereis an ear,- A, having an opening in them' near their up- *per e'ndsto receive a ro'dor bolt, B.

The rodorpasses through an 'opening b, .in the. upper-'en'd'of the cover or"cap,.said'--opeuing bo ingot oblong form in itsftrans'verse section to;

admit of a certain degreeot playfor thec'overj' or'cap, sutficient to allow the lower'end of the latter to'work in and on by the lip a.

The cover or cap tof the recessforrned j is made-with apoclifetoir,

end of which bears on the bottomof said pocket or chamber and the other end against the rod or bolt B, as shown clearly in Fig. 4.. This spring, it will be seen, has a tendency to keep 'thelower end of the cover or cap within the j recess formed by the lip a. i

:Theiow-er outer surface of the cover or cap 'is beveled or-inclined, corfesponding' to the---- inclination of the lip a, as shown at a" inFig. 2. These inclined surfaces of the. parts re- I ferred to cause the cap or cover to be pressed snugly to the sides of the box, thereby preventing the admission of dust, dirt, and other foreignsdbstances. The oblong opening bis parallel transversely with the inclined sides of the box, against which the cover or cap'bears,
