We, JOHN WALKER, of Beeston Hill, Leeds, Mechanical Engineer, and;
WILLIAM TATE, of West Ardsley, near Wakefield, Mining Engineer, both in the..
County of York, do hereby declare the nature of this invention to be as
follows:
"
The object of this invention is to construct axle boxes suitable for colliery tubs
and the like in such a manner that the axle rotating in the box may be
automatically lubricated; also to so arrange the boxes that, the axles may be
readily removed for examination and repairs.
We accomplish our object in the following manner :-We form an axle box or
pedestal having a receptacle placed in such a position that, on filling same with
lubricant, it is brought in contact with the axle by its own gravity or by aid of a
weight or spring acting on a plate in the receptacle..
The axle is secured in each box by a cap jointed at one end to the box, and
secured at the other end by bolts or other suitable fastening, the portion of the
cap engaging in the recess of the axle block being curved to allow for the easy
insertion and withdrawal of the same.
Dated this 22nd day of December 1892.

COMPLETE SPECIFICATION.
Improvements in the Construction of Axle Boxes.
We, JOHN WALKER, of Beeston Hill, Leeds, Mechanical Engineer, and
WILLIAM TATE, of West Ardsley, near Wakefield, Mining Engineer, both in the
County of York, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of this invention is to construct axle boxes suitable for colliery tubs
and the like in such a manner that, the lubricant is in constant contact with the
axle journal, thereby automatically keeping the same lubricated: also to so
arrange the boxes that, the axle may be readily removed for examination and
repairs.
In describing our invention in detail, reference is made to the accompanying
drawings, in which
Fig. 1 represents the side elevation of an axle box constructed according to our
invention,
Fig. 2 is a front view of the same, and
Fig. 3 a section through line a. b.
The axle box pedestal A, is prepared with a receptacle B for the reception of
the lubricant which is brought in contact with the journal portion of the axle C
when the box A is secured in an upright position by its own gravity assisted by a
weight W acting on a plate in the receptacle B, or when the box pedestal A is
placed flat under the colliery tub or the like, a spiral spring may be utilized for
the weight W for forcing the lubricant into contact with the journal portion of the
axle.
The axle C is secured in each box pedestal A, by a cap D, jointed at E, the
other end being attached to the box by a bolt F, or other suitable fastening, the

page_text: portion of cap D engaging in the recess of the axle block of box pedestal A,
being curved at D' to allow of the easy insertion and withdrawal of the cap D,
thereby facilitating the removal of the axles for examination and repairs.
By forming and connecting the cap D to the axle box pedestal A, in the
manner described, the axle journal is shielded, thereby preventing dust coming in
contact with the journal.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
An axle box pedestal A having a receptacle B communicating with the axle
journal combined with a cap D jointed thereto in a manner for keeping the dust
and other foreign matter from the axle journal, all arranged substantially in the
manner as shown and described.
