SPECIFICATION
Improvements in Bearings for Shafts, Axles, and for like purposes.
We, LAURANCE WORTHINGTON, Engine Fitter, and JOHN SOAR, Underground
Manager, both of Bolsover Colliery, Bolsover, in the County of Derby, do hereby
declare the nature of this invention to be as follows:-
Our invention has reference to an improved method of constructing bearings and
adapting them for use for axles to revolve in, when attached to a tramcar, mine
corve, wheel barrow, or other vehicle; also for enabling shafts to revolve in when
carrying pullies and the like upon such shafts. The object of our invention being
to provide an adjustable bearing and one which can be readily renewed while the
arrangement of the cap or holder is such as to take all the strain from the bolts by
which it is attached.
In carrying our invention into effect we form a strap or holder of cast or wrought
metal having a flange on each side preferably through which a hole. or holes are
formed for passing a bolt or bolts through, but on the upper surface of each flange
we provide ribs or projecting spike like ears which enter into and engage with the
wood or material of the truck vehicle or board to which it is anchored, so that when
the bolts pass through the holes these projecting beads prevent the strain being
solely taken by the bolts and obviate the vibration common to the ordinary type of
bearing in which the bolts alone carry the load.
We form a gap between our flanges into which we introduce a block for carrying
the brass or bush and we form the necessary seating within this block to suit the
shape of the brass or bush that is to be employed.
We provide recesses within the ends of the block to enable it to slide up and
down upon projections formed upon the gap sides of our strap or holder.
On the upper surface of our bush block we place a spring or springs preferably
of spiral form, and we allow the end or upper coil to enter into a thimble which we
drive into or attach to the train spending or framework to which the bearing is
attached, arranging on the thimble suitable spikes or rib pieces for preventing
motion within the hole which is bored for its reception. We lubricate the axle in
one convenient manner by means of a tube passing through the spring and leading
to the oil cup formed on the bush block.
We do not limit the application of our invention to any particular shape of
holder or to any special form of brass or bush, but we modify the shape of the
same to suit the purpose for which the bearing is intended and to suit the form of
vehicle or framework to which the bearing is to be secured.

We, LAURANCE WORTHINGTON, Engine Fitter, and JOHN SOAR, Underground
Manager, both of Bolsover Colliery, Bolsover, in the County of Derby, 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 :-
Our invention has reference to an improved method of constructing bearings and
adapting them for use for axles to revolve in, when attached to a tram car, mine
corve, wheel barrow, or other. vehicle; also for enabling shafts to revolve in when
carrying pullies and the like upon such shafts. The object of our invention being
to provide an adjustable bearing and one which can be readily renewed while the
arrangement of the cap or holder is such as to take all the strain from the bolts by
which it is attached.
In the accompanying sheets of illustrated drawings
Figure 1 is a sectional side elevation.
Figure 2 a sectional end elevation and
Figure 3 a plan of one form of our improved bearing.
Figure 4 is a side elevation and
Figure 5 an end elevation of another form of our improved bearing having no
spring or sliding block.
In carrying our invention into effect when constructing a bearing in the form
shown in Figures 1, 2 and 3 we arrange a strap or holder A of cast or wrought
metal having a flange a a' on each side preferably through which a hole or holes
are formed for passing a bolt or bolts B through, but on the upper surface of each
flange we provide ribs or projecting spike like ears c which enter into and engage
with the wood or material D of the truck vehicle or board to which is anchored;
so that when the bolts pass through the holes these projecting heads prevent the
strain being solely taken by the bolts and obviate the vibration common to the
ordinary type of bearing in which the bolts alone carry the load.
We form a gap between our flanges into which we introduce. a block E for
carrying the brass or bush and we form the necessary seating within this block to
suit the shape of the brass or bush that is to be employed or we may make the
block. E without a bush or lining forming the bearing surface in the block itself.
We provide recesses within the ends of the block to enable it to slide up and
down upon projections A' formed upon the gap sides of our strap saddle or
holder A.
On the upper surface of our bush block or pad E we place a spring F or springs
preferably of spiral form, and we sometimes allow the end or upper coil to enter
into a thimble Gwhich we drive into or attach to the tram spending or frame-
work D to which the bearing is attached, arranging on the thimble suitable spikes
or rib pieces g for preventing motion within the hole which is bored for its
reception. We lubricate the axle in one convenient manner by means of a
tube H H passing through the spring and leading to the oil cup e formed on the
bush block.
When constructing a bearing without a spring we sometimes make it of the form
shown in Figures 4 and 5 in which our sliding or separate bearing block E³ enters
between the strap or holder A' the holder having projecting guards or keeps a³ a
formed thereon of such a shape as to fit snugly upon the block E2 so as to take
up the side strains and to relieve the load upon the bolts. For instance if the
block E be cylindrical as shewn then the contact surfaces of the keeps as a will
be semi-cylindrical. The block E has the bed formed within its underside for the

page_text: shaft or axle to revolve in or a bush piece or liner may be used when preferred
instead.
We do not limit the application of our invention to any particular shape of
holder or to any special form of brass or bush, but we modify the shape of the
same to suit the purpose for which the bearing is intended and to suit the form of
vehicle or framework to which the bearing is to be secured.
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-
1. The improvements in bearings for axles spindles and for like purposes
substantially as and for the purpose herein before described and as illustrated in
the accompanying drawings.
2. In a bearing for a truck, wagon or like vehicle the arrangement of a strap or
holder to receive an independent block or bed piece for the shaft spindle to revolve
against substantially as herein before described and as illustrated in the accompanying
drawings.
3. In an axle bearing for a truck wagon or like vehicle the arrangement of a
holder or saddle having a spring for keeping the independent bearing block or pad
in contact with the shaft or axle substantially. as hereinbefore described and as
illustrated in the accompanying drawings.
