PROVISIONAL SPECIFICATION.
Improved Axle Bearing for Colliery Corves, Tip Wagons, and
the like.
I, EDWIN WILSON DRURY of Handsworth Hill, Darnall in the County of
York, Wheelwright, do hereby declare the nature of this invention to be as
follows:-
-
This invention relates to the metal bearings which receive the necks of the
axles of pit corves, tubs, wagons, tip wagons and the like vehicles, having for its
object to construct a bearing at once simple and effective.
Such bearings are usually composed of a casting to be fixed by bolts underneath
the body of the corve having a semicircular bearing part which rest upon the neck
of the axle, and a strap of wrought iron passing loosely round the axle and held by
the bolts which secure the bearing to the corve.
These straps are very liable to shake loose and hitherto have been found
troublesome from various causes.
I propose to make the bearing with two transverse recesses or grooves across the
face that is to be in contact with the body of the corve, say for example half inch
wide and half inch deep and a little wider apart than the diameter of the axle.
The central bearing portion of the casting extends on each side about half an
inch beyond the other or end parts.
I make the strap which passes round the axle of a U shape, and bend its ends
back so as to lie in the recesses across and flush in the face of the casting, and the
extreme projecting ends are bent sideways or hooked to prevent them being
drawn out of the recesses when the casting is bolted to the corve.
I may however vary the construction so far as the means of preventing the
withdrawal of the strap, and I may use transverse holes through the casting
instead of open recesses or grooves.

Improved Axle Bearing for Colliery Corves, Tip Wagons, and
the like.
I, EDWIN WILSON DRURY of Handsworth Hill, Darnall in the County of
York, Wheelwright 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 the metal bearings which receive the necks of the axles
of pit corves, tubs, wagons, tip wagons and the like vehicles, having for its object
to construct a bearing at once simple and effective.
Such bearings are usually composed of a casting to be fixed by bolts underneath
the body of the corve, having a semi-circular bearing part which rests upon the
neck of the axle, and a strap of wrought iron passing loosely round the axle and
held by the bolts which secure the bearing to the corve.
These straps are very liable to work loose, and hitherto have been found

page_text: troublesome from various causes, for instance, if the nuts of the bolts that keep
the straps in position should come off, the strap would also be liable to come off.
I propose to make the bearing with two transverse recesses or grooves across
the face that is to be in contact with the body of the corve, say for example half
inch wide and half inch deep and a little wider apart than the diameter of
the axle.
I make the strap which passes round the axle of a U shape, and bend its ends
back so as to lie in the recesses across and flush in the face of the casting, and the
extreme projecting ends are bent sideways or hooked to prevent them being drawn
out of the recesses when the casting is bolted to the corve, thus it will be seen
that even if the nuts of both bolts securing the bearing in position were to come
off, the strap would still remain in its place.
In the drawing hereto annexed, I show an axle bearing constructed according to
this invention, Fig. 1 is a plan view, Fig. 2 a side elevation and Fig. 3 an end
elevation.
The same letters indicate the same parts in each illustration.
A is the metal bearing, B the semi-circular surface upon which rests the neck
of the axle. D. D. (Fig. 2) are the recesses cast in the side of the bearing, which,
at right angles to this side, are continued transversely E. E. across the face that is
be in contact with the body of the corve, these recesses terminating in two small
square recesses F. F. on the opposite side of the bearing. G is a U shaped strap
of wrought iron or other metal which passes round the axle having its two free
ends bent at right angles, these ends being hooked H. H. (Fig. 1) at right angles
to the latter direction.
The general operation may be briefly described thus:-The axle neck is laid in
the semi-circular surface B, the strap G is passed over it and placed in the
grooves E. E. and the square recesses F. F. the free ends of the strap, when
thus placed, being flush with the base of the bearing. The bearing thus fitted is
then placed in its position and securely fixed to the body of the corve by the two
bolts C. C. The strap G is now securely held in position longitudinally by reason
of its two ends being bedded into the grooves E. E. and is likewise securely held
in position laterally by the hooked ends H. H. being bedded into the recesses F. F.
all risk of slipping or dropping out being thus rendered impossible.
The construction so far as the means of preventing the withdrawal of the strap
laterally is concerned may be varied, inasmuch as I may employ a screwed nut or
a cotter in lieu of the hook, and further I may use transverse holes through the
metal bearing in lieu of the recesses, securing the two free ends of the strap by
nuts or cotters or by riveting them over.
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 metal bearing having two recesses cast in one side which are continued
transversely along the base and terminate at the opposite side in two square
recesses substantially as described and shown in the drawings.
2. A strap of wrought iron or other metal and of square or other suitable
section bent in semi-circular shape, the ends of which are also bent at right angles
and terminate in a retaining hook substantially as described and shown in the
drawings.
