PROVISIONAL SPECIFICATION.
Improvements in Spring Bearings for the Axles of Colliery Tubs,
Contractors' Waggons, and the like.
We, FRANCIS HOLLINS WARDEN, of 28, Lionel Street, in the City of
Birmingham, Iron Merchant, and RALPH HODGSON, of 47, Malvern Street,
Sparkbrook, Worcestershire, Mechanic, do hereby declare the nature of this
invention to be as follows:-
This invention consists of the hereindescribed improvements in spring bearings
for the axles of colliery tubs, contractor's waggons and other small waggons which
are constructed to run on rails. As these tubs or waggons as usually constructed
have no springs to their axles, it often happens that through the inequalities of the
rails one of the wheels will be riding some distance above the rails and may come
down on the wrong side of the rails thus throwing the tub or waggon off the rails
and thereby causing damage and considerable delay. By this invention we construct
a cheap and effective spring bearing for the axles of the said tubs or waggons which
has the effect of always pressing the wheels down on to the rails no matter what
the inequalities of the latter may be, thus effectually preventing the tubs or waggons
from running off the rails.
In carrying out this invention each of the said bearings consists of a top bearing
block adapted to fit on to the axle and provided with an upwardly projecting tubular
stem preferably of cylindrical shape fitting easily inside or outside a metal socket
which is fixed to the underside of the timber underframe of the tub or waggon. The
said tubular stem and socket contain a coiled wire or other spring which acts
between the top of the socket and the bearing block and forces the bearing block
downwardly so that the axle wheels accommodate themselves to the inequalities of
the rails and the tub or waggon is prevented from running off. In order to prevent
the axle from falling away from its bearings and also to prevent the bearing blocks
coming off their sockets each of the bearings has a wrought iron or other loop or
strap which passes underneath the axle and is fixed to the socket or to the wooden
underframe of the tub or waggon so that when the bearing block has forced the axle
down as far as it is intended to go the axle will come in contact with this loop and
thus be prevented from being forced out too far.

Improvements in Spring Bearings for the Axles of Colliery Tubs,

We, FRANCIS HOLLINS WARDEN, of 28, Lionel Street, in the City of
Birmingham, Iron Merchant, and RALPH HODGSON, of 47, Malvern Street,
Sparkbrook, Worcestershire, Mechanic, 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 consists of the hereindescribed improvements in spring bearings for the
[rce 8d.1

page_text: axles of colliery tubs, contractor's waggons and other small waggons which are con-
structed to run on rails. As these tubs or waggons as usually constructed have no
springs to their axles, it often happens that through the inequalities of the rails one
of the wheels will be riding some distance above the rails and may come down on the
wrong side of the rails thus throwing the tub or waggon off the rails and thereby
causing damage and considerable delay. By this invention we construct a cheap
and effective spring bearing for the axles of the said tubs or waggons which has the
effect of always pressing the wheels down on to the rails no matter what the
inequalities of the latter may be, thus effectually preventing the tubs or waggons
from running off the rails. Our said invention also ensures perfect lubrication of
the bearings.

This invention is illustrated by the accompanying drawing on which Fig. 1 is
cross sectional elevation of a spring bearing constructed according to this inven-.
tion; Fig. 2 is a front elevation of the same with the axle shewn in section and
Fig. 3 is a plan of the same.
The same letters of reference indicate the same parts in all the figures.
In carrying out this invention each of the said bearings consists of a top bearing
block A adapted to fit on to the axle B and provided with an upwardly projecting
tubular stem a preferably of cylindrical shape fitting easily inside a metal socket C
which is made with a base e fixed as by the two bolts g' 92 to the underside of
the timber underframe D of the tub or waggon. The tubular stem a and socket C
contain a coiled wire or like spring E which acts between the top c of the socket C
and the bearing block A and forces the bearing block A downwardly so that the
wheels on the axle B accommodate themselves to the inequalities of the rails and
the tub or waggon is prevented from running off. F is a cast steel or other loop
or strap shaped as shewn so as to pass underneath the axle B and bear against
the collar of the same this loop or strap F being made with feet flf fixed
to the underside of the base c¹. When the bearing block A has forced the axle B
down as far as it is intended to go the axle B will come in contact with the lower
part of this loop F and thus be prevented from being forced out too far or from
falling away from the bearing block when the waggon is lifted or tipped. The
loop or strap F. bearing against the collar b.also prevents the axle B from
moving endwise. The bearing block A is shaped so as to easily fit in the
loop which latter therefore forms a guide for the bearing block A as it moves up
and down.
The sockets a and C together form a convenient oil cup for lubricating the axle.
The oil can be poured into the cup a through the oil hole h in the socket C and the
ail runs on to the bearing through the oil hole i in the bearing block A.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The improved spring bearing for the axles of colliery tubs, contractor's waggons
and the like, said bearing consisting of the top bearing block A adapted to fit
on the axle and made with the tubular shank a taking into an inverted socket fixed
to the underframe, said shank a and socket e forming an oil box and containing
a coiled or like spring E which forces the bearing block downwardly, the said
bearing block being guided and prevented from moving too far by the loop F
which passes under the axle and forms a guide for the same, all substantially as
herein set forth.
