COMPLETE SPECIFICATION.
Improvements in Axle Boxes for Railway Vehicles and the like.
I, EDWARD WILLIAM MACKENZIE-HUGHES, of 33, Renfield Street, in the
County of the City of Glasgow, North Britain, Consulting Engineer, 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, that is to say :-
My said invention has for its object the construction of axle boxes for railway
vehicles and the like in an improved and simplified manner and comprises.
improvements in the invention described in my Patent Specification No. 14617
of 1890.
In carrying out my invention I have the body of the axle box made of pressed
steel or other metal and with external flanges to fit and slide on the horn guides.
of the vehicle framing as in my former arrangement. The improvement consists.
in making the crown of the box separate from the body and of one piece of
steel or other metal rolled and welded so as to enclose a space for containing
lubricant for the axle journal.
And in order that my said invention and the manner of performing the same.
may be properly understood I hereunto append a sheet of explanatory drawings to
be hereinafter referred to and showing an axle box as made with my improve-.
ments.
Figure, 1, of the drawings is an outside elevation. Figure, 2, is a longitudinal
vertical section and Figure, 3, a transverse vertical section. Figures, 4, and, 5,.
are transverse vertical sections of the piece forming the crown of the axle box,
before and after being welded. In these drawings the same reference letters are
used to mark the same or like parts wherever they are repeated.
As shown in the drawings the body, A, of the axle box is made of a piece of
steel or other metal rolled of a suitable section and pressed or bended into a
suitable shape. Its outer end is closed by a plate, B, bolted on and its inner
end is fitted with a dust guard, C. The body, A, of the axle box is also formed
at its middle part with flanges, D, to fit and slide on the horn guides of the
vehicle framing. The crown, E, of the axle box is made of steel or other metal
rolled to a suitable section such as is shown in Figure, 4, and then bended over
a mandrel and welded into a simple form such as is shown in Figures, 2, 3, and, 5,.
80 as to form a chamber, F, for containing the grease or other lubricant. The
metal for forming the crown, E, may be rolled of the required section in long
lengths and then cut to suit. The chamber, F, is closed at the ends by screwed
plugs, G, and, H, the outer one, G, of which can be unscrewed for filling the
chamber with lubricant. The crown, E, is fixed to the body, A, of the axle box
by screw pins, J. The brass, K, which bears on the journal, L, is fitted to the
crown, E, and an aperture, M, is formed in it communicating with the chamber, F,
and giving the lubricant access to the journal.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. The improved construction of axle box for railway vehicles and the like
substantially as hereinbefore described.

page_text: 2. Forming the crown of an axle box for railway vehicles and the like of a
separate piece of rolled steel or other metal so as to enclose a space for containing
the lubricant substantially as hereinbefore described.
