PROVISIONAL SPECIFICATION.
Improvements in Colliery Corves and other similar Trucks or
Waggons.
I, JOHN GILL, of Saw Yard, Wakefield, in the County of York, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements in colliery corves and other similar
waggons, and its object is to provide cheaper and better means of securing the
wheel axles in the bearings formed in the bearing fixings or pedestals secured
beneath the corve.
For this purpose I form a lateral extension on each side of the fixings, that is
to say: I increase their breadth and I employ a U shaped clasp which may be
imade of iron of square cross section. This U" shaped clasp embraces the axle
and the ends pass up close to the side of the fixing and are bent round laterally so
as to hook over into a recess formed in the back or top of the fixing, consequently
when the fixing is attached it is impossible to unhook the ends of the clasp or
remove the axle from its bearings.
To enable the fixing to be turned on to its side when detached from the corve to
release the hooked ends of the clasp I round off the end of the bearing next to the
clasp sufficiently to clear the axle whilst the fixing is turned for this purpose.
Lugs or projections are preferably cast on the side of the fixing to form guides or
supports for the sides of the clasp.

COMPLETE SPECIFICATION.
Improvements in Colliery Corves and other similar Trucks or
Waggons.
I, JOHN GILL, of Saw Yard, Wakefield, 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:-
This invention relates to improvements in colliery corves and other similar
waggons, and its object is to provide cheaper and better means of securing the
wheel axles in the bearings formed in the bearing fixings or pedestals secured
beneath the corve.
To fully describe my invention reference is made to the accompanying sheet of

drawings forming a part of this specification, in which similar letters of reference
indicate corresponding parts in each of the figures.
Figure 1, is a side view of a corve axle-bearing pedestal made in accordance
with my improvements.
Figure 2, is a plan view of the same.
Figure 3, is a cross section on the broken line
Figure 1.
Figures 4 and 5, represent a separate side and end view of the "U" shaped clasp
employed to secure the axle in the bearing.
The pedestal or fixing A is made wider on the side A2 of the clasp B and a
recess is made in the top. The "U" shaped clasp B is preferably made of
iron of square cross section. It embraces the axle C and its upper ends 1ª are
hooked over round the side A+ of the recess A³. Consequently when the pedestal
is bolted to the framework of the corve in the usual way after the pedestal and
strap have been placed in position on the axle it is practically impossible for the
axle to be removed without the pedestal is first detached from the bolts securing it
to the corve.
Furthermore if the said bolts should be accidently broken, in all
probability, the axle would not escape from the pedestal for, even though the
latter swung round underneath the axle, the clasp B would support. it thereon,
as the hooked ends 132 are preferably made long enough to have sufficient hold of
the side A+ for this purpose.
To enable the hooks 12 to be hooked round the side A, when the clasp is on
the axle C. the pedestal is turned with its side A against the axle, then the side A+
of the recess is passed under the points of the hooks and the pedestal is turned
from its side to the position shown and by this movement the side A is passed into
the hooks. The end E of the bearing is rounded off as clearly shown in Figure 3,
to permit of the pedestal being turned in this way. The clasp B, is preferably made
large enough to permit of it being slightly raised whilst the pedestal is turned
and thereby facilitate the side A+ being passed into the hooks B. Of course this
is done previous to the pedestal being bolted to the corve, and before the axle can
be removed from the bearing E it is necessary to first detach the pedestal from the
corve.
Lugs or projections A5, A5 are preferably cast on the side of the pedestal to form
guides or supports for the sides of the clasps.
The framework of the corve is notched or recessed to receive the tops of the
hooks B projecting above the pedestal.
Having now particularly described and ascertained the nature of my said inven
tion, and in what manner the same is to be performed, I would have it understood
that I do not broadly claim a "U" shaped clasp but what I do claim is:-
1. The combination with a bearing pedestal or fixing of a corve or similar
waggon, of a clasp embracing the axle and having hooked ends adapted to engage
and be secured to the side of a recess formed in the back of the pedestal, substan-
tially as herein shown and described.
2. In a corve the combination with the pedestal A having a recess A³ and lugs A
of the clasp 1 made with hooked ends 12 for the purpose specified, substantially
as herein shown and described and illustrated in the accompanying drawings.
