A further and particular object of the invention 18 to
provide a device wherein the pan is maintained in posi

which with the oil pan may be readily inserted, when
de?ated, into the standard journal box surrounding an
axle journal, and when in?ated urges the pan upwardly
into required position in relation to the journal.
Another object of the invention is to form the pan of

contact.
To insert the lubricating device in place the bag 13 is
de?ated by opening the valve 14 and the bag and oil
pan, which are relatively pliable, inserted into the journal
box 7 to a position wherein the oil pan underlies the
journal 4. The bag upon in?ation presses against the
inside faces of the sides and bottom of the journal box
and thus presses the ribs 9, 10 and 12 into contact with
pliable rubber-like material and to provide several semi
circular ribs upon its inner surface, the ribs engaging the 25 the face of the journal 4, the rib 9 constituting an oil
seal at the inner end of the pan. Oil is then poured into
