PROVISIONAL SPECIFICATION.
Improvements in or connected with Colliery Tub and other
like Wheels.
I, WILLIAM FREDERIO BUTLER, of Highfield Road, Wrexham, in the County of
Denbigh, North Wales, Colliery Proprietor, do hereby declare the nature of my
said Invention to be as follows:-
This Invention relates mainly to the wheels on which colliery tubs and like trucks
or vehicles are mounted and run and in which the axles are stationary, and the
wheels mounted on the ends thereof and revolve freely thereon. This Invention is
very applicable to colliery and other tub or like wheels, where the curves of the
track on which the carriages have to run have small radu, and more especially where
these radu are small and the rate of speed at which the carriages travel is com-
paratively high, say from 8 to 10 miles per hour.
A colliery or like tub or truck wheel with improvements according to my invention
applied thereto consists as follows
annular or
The rim of the wheel is constructed in the ordinary way and provided with an
ordinary flange, and at the centre of the wheel I provide a hub in which the end of
the fixed axle is placed and on which the wheel works. Disposed between the hub
and the 1m of the wheel I provide an annular or suitably shaped web running
from front to back of the hub and parallel thereto and at the back of the wheel I
provide a disc or web connecting the hub and outer ring thus enclosing the
space between the hub and the outer ring and forming it into an
other suitably shaped box open at one end. This box I use as a lubricant box
and I provide in the open end a cap which serves to keep in the lubricant and
also as a means of gaining access to the interior of the box and the axle fittings, and
holding on device. The lubricant may be introduced into the box through a suitable
stoppered feed aperture or cup, placed conveniently upon the outer surface of the
outer box ring.
The rim of the wheel and the interposed ring, and the ring and the hub are
respectively connected together by arms, or webs, which are by preference so
arranged, as are also the rim ring and hub, that these parts may all be cast in one piece
by a simple and plain pattern and mould; the only separate part therefore being the
lubricant box cap. By this construction the wheels may be constructed very quickly
and cheaply either in cast iron or steel.

COMPLETE SPECIFICATION.
Improvements in or connected with Colliery Tub and other
like Wheels.
I, WILLIAM FREDERIC BUTLER, of Highfield Road, Wrexham, in the County of
Denbigh, North Wales, Colliery Proprietor, do hereby declare the nature of my said
Invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This Invention relates mainly to the wheels on which colliery tubs and like trucks
or vehicles are mounted and run, and in which the axles are stationary, and the
wheels mounted on the ends thereof and revolve freely thereon. This invention is

page_text: very applicable-to colliery and other tub or like wheels, where the curves of the track
on which the carriages have to run i have-small. radi, and more especially where
these radu are small and the rate of speed at which the carriages travel is comparatively
high, say from 8 to 10 miles per hour.
A colliery. or like, tub or, truck wheel, with improvements according to my; Invention
applied thereto, consists as follows:
The rim of the wheel is constructed in the ordinary way and provided with an
ordinary flange, and at the centre of the wheel I provide a hub in which the end of
the fixed axle is placed and on which the wheel- works. Disposed between the hub
and the rim of the wheel,I provide an annular or suitably shaped web, running from
front, to back of the hub and parallel, thereto, and at the back of the (wheel, (pro-
vide a disc or web, connecting the hub and outer ring, thus enclosing the space
between the hub and the outer ring and forming it into an annular or other, suitably
shaped box open at one end. This box, I use as a lubricant, box,, and I provide in
the open end a cap which, serves to keep in the lubricant and also as a means of
gaining access to the interior of the box and, the, axle fittings, and, holding on device.
The lubricant may be introduced into the box, through a suitable stoppered, feed
aperture, or cup, placed conveniently upon the outer surface of the outer box
ring.
The rim of the wheel and the interposed ring, and the ring and the hub,, are
respectively connected together by arms, or webs, which are by, preference, so
arranged, as are, also the rim, ring, and, the hub, that, these parts may all be cast in
one piece, by a simple, and plain, pattern,and, mould; the only separate, part therefore
being the lubricant box cap. By this construction,, the wheel may, be, constructed
very quickly and cheaply, either in cast, iron, or steel.

I will now proceed to describe my Invention by the aid of the, accompanying
Drawings, which make a part of this specification, and, illustrate a colliery tub wheel
provided with improvements according to my. Invention. The Drawings are marked
with letters, and figures of reference, which correspond with those used in the following
explanation.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front view of the wheel, with the cap or cover of the lubricant box
removed.
Figure 2, is a sectional, end elevation of the wheel, taken, at, a.a, Figure 1.
With reference to, the Drawings; a, designates, the rim, of, the wheel,, which is
constructed in the ordinary way and provided with an ordinary flange, a'. At the
centre of the wheel I provide a hub, b, in, which, the end, of the fixed axle,c, is
placed, the wheel running on the part, c', of the axle. Between the; hub b and the
rim a of the wheel, and connected to the rim a by, arms or a web, I provide a ring
web d, which runs from the front to the back of the hub b, and is connected to the
back of the hub by a webb, thus forming an annular chamber or box, e, open at
the front. The box, .e, I use as a lubricant box, and I provide it with a cap or
cover h, which serves to keep, in, the lubricant, and, also as a means of getting at the
interior of the box and 'the axle holding device. The cap h is screwed into or
otherwise attached to the ring-web-d, and is provided with a pin.i,to prevent it from
turning and coming off. There is provided a stoppered feed aperture, k, in the web d,
through which the lubricant may be introduced into the box ce, by removing the
plug or stopper, ¹; or the-boxe may be filled with grease by removing the cap.
It will be seen that the construction of the wheel is such, that the rim :a,iweh.or
ring d, and the hub b,-together with the connecting, arms, or webs, may be cast all
in one piece, and, the, only separate part is the cap h, thus providing for a simple, and
cheap construction, and at the same time providing an axle hox in which the axle
fittings are encased and protected.

page_text: 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. A colliery tub or other like wheel, substantially as described, that is to say, a
wheel having a chamber round the hub thereof and adapted to serve as a lubricant
chamber to the axle on which the wheel works.
2. A colliery tub, or other like wheel, comprising an outer rim, a hub, and an
intermediate ring or web, and a cap or cover, the chamber formed between said
hub and said ring or web being constructed and adapted to be used as a lubricant
box, and whereby a casing or covering is provided and the axle fittings protected as
set forth.
3. A colliery tub or other like wheel, having a lubricant box, e, and cap, h, arranged
and adapted to be used substantially as herein described.
