COMPLETE SPECIFICATION,
Improvements in Bearings for the Axles of Corves, Trollies, Bogies,
Trucks, and the like Mining, Railway, and Tramway Vehicles.
I, MARK LITTLEWOOD, of Cwm Clydach, Swansea Valley, in the County of
Glamorgan, Mining Engineer, do hereby declare the nature of my said invention
for "IMPROVEMENTS IN BEARINGS FOR THE AXLES OF CORVES, TROLLIES,
BOGIES, TRUCKS
AND THE LIKE MINING, RAILWAY AND TRAMWAY
VEHICLES and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
23
Although my invention is applicable to a variety of railway and tramway
vehicles, a description of it as applied to a colliery corve will suffice.
The objects of my invention are to provide a self oiling bearing which can be
taken out and replaced without removing the gland, or the wheels and axle and one
where the wheels and axles can be changed without removing the bearings, and by
means of which
economize in lubricants and tractive force.
I attain these objects in the following manner :-
I construct the frame or pedestal of my improved bearing so that it may be
permanently bolted or otherwise secured to the frame or sole of the corve. This
pedestal I provide with a dovetailed recess for the reception of a loose bearing or
brass, the loose bearing or brass being formed with a corresponding dovetailed base
so that it can be placed or slided sideways into the pedestal, and when so placed
can be further secured by set-screws, bolts or their equivalents.
This loose bearing or brass I also construct with a recess or cavity for containing
oil or other lubricant with an opening or openings extending for some distance over
that portion of its circumference which comes in contact with the axle and by means
of which the axle and the bearing may be continually lubricated.
The gland or strap for retaining or securing the axle under the bearing I attach
to brackets or projections formed on one side of the pedestal, these projections being
provided with suitable holes or slots by means of which the ends of the gland may
be secured by split pins, cotters or other equivalent fastenings.
The nature of my invention will be better understood on reference to the accom-
panying sheet of drawings in which,
Fig. 1, represents a side elevation of the frame or pedestal, the loose bearing or
brass and gland being removed.
Fig. 2, being an end elevation, and
Fig. 3, a plan of the same.
Fig. 4, represents the loose bearing or brass before it is inserted into the frame or
pedestal.
Fig. 5, being a plan of the same, and
Fig. 6, a section on the line A. B.
Fig. 7, represents a side view of my improved bearing with the loose bearing or
brass and likewise the gland in position, as at work.
Fig. 8, being an end view of the same, and
Fig. 9, a section of the same also through the line A. B.
The same letters refer to similar parts throughout the several views.
",
is the pedestal or frame.
b, is the dovetailed recess for the reception of the loose bearing or brass.
c, c, are brackets or projections to which the ends of the strap or gland are
secured.
d, d, are the bolt holes by means of which the pedestal is secured to the frame or
sole of the corve, and
.
e, e, are the bolt holes by means of which the loose bearing or brass is secured in
the dovetailed recess;

page_text: fare holes or recesses for the ends of the strap or gland, and
9, 9, are holes or slots for the cotters or pins for securing the same.
h, is the loose bearing or brass.
i, the dovetailed base corresponding to the recess "" in the pedestal.
jare bolt holes corresponding to bolt holes, e, e, in the pedestal.
A, is the oil recess or cavity in the same.
1, is the strap or gland, and
m, m, are the split pins or cotters by means of which the ends are secured to the
projections, c, in the pedestal.
n is a strip of packing which may or may not be used as required, and
0,
is the axle.
It will be seen from the accompanying drawings and foregoing references, that
the loose bearing or brass, h, can be slided in or out of its position in the dovetailed
recess, b, in the pedestal, a, as soon as the bolts or set screws are removed from the
holes, e, e, without the necessity of removing the wheels and axle and it will also be
seen that when the loose brass or bearing, h, is secured into the dovetailed recess
in the pedestal by the bolts or set screws as previously referred to, that on removal
of the gland, /, the wheels and axle can be removed and changed without disturbing
the brasses or bearings.
In some classes of vehicles such as a platelayer's trolley a stiff grease may be
used in the oil space, k, similar to that employed in the axle boxes of ordinary
railway waggons.
In other classes of vehicles such as colliery corves or trams, detached self oiling
appliances similar to those in use at collieries and other mines may be employed
and by means of such appliances the axles of the vehicles fitted with my improved
bearings will take off the oil from such appliances in passing over the same and the
oil so taken up by the axles will be carried round with the axles into the recesses k, k.
from whence it will be again given off to the axles as required for lubrication.
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed, 1.declare that what I
claim is :
(1.) In bearings, for the axles of corves, trollies, bogies, trucks and the like
mining, railway and tramway vehicles the arrangement and combination of parts
and appliances comprising the frame or pedestal with its dovetailed recess, the loose
bearing or brass fitting sideways into the same, with its oil cavity or recess, the set
screws, bolts or other equivalent fastenings by means of which the last named parts
are further secured to one another and to the vehicle substantially as and for the
purposes herein set forth and illustrated on the accompanying sheet of drawings.
(2.) In bearings for the axles of corves, trollies, bogies, trucks and the like
mining, railway and tramway vehicles the arrangement and combination of parts
and appliances comprising the frame or pedestal with its dovetailed recess the
brackets or projections formed on one side of the same, the loose bearing or brass,
with its oil cavity, fitting sideways into the dovetailed recess in the pedestal, the
gland or strap attached to the brackets or projections formed on one side of the
pedestal, together with the set screws, bolts, cotters, split pins or other equivalent
fastenings by means of which the several parts may be further secured to one
another and to the vehicle substantially as and for the purposes herein set forth and
illustrated on the accompanying sheet of drawings.
(3.) Improvements in bearings for the axles of corves, trollies, bogies, trucks and
the like mining, railway and tramway vehicles substantially as and for the purposes
herein set forth and illustrated on the accompanying sheet of drawings.
