Improvements in Colliery Tubs or Corves and the like Tramway
Vehicles and in Apparatus and Appliances connected therewith,
also applicable to other classes of Vehicles.
I, JOHN MARSHALL of Hoyland Common, near Barnsley in the County of
York, Colliery Clerk, do hereby declare the nature of my invention for "IMPROVE
MENTS IN COLLIERY TUBS OR CORVES AND THE LIKE TRAMWAY VEHICLES
AND IN APPARATUS AND APPLIANCES CONNECTED THEREWITH
APPLICABLE TO OTHER CLASSES OF VEHICLES," to be as follows:-
ALSO
Although my invention is applicable to a variety of vebicles a description
of it as applied to a colliery corve will suffice. The objects of my invention are
threefold riz. :-
First. To construct a corve which shall run more easily and require less tractive
force to haul it, than is the case with corves as commonly constructed.
Second. To provide a more simple, effective and economical
lubricating the bearings than the methods at present in use.
method of
Third. To provide a stronger sole or framing than is commonly used in ordinary
Corves.
I effect these objects in the following manner:
First. Instead of the corve axle revolving in an ordinary bearing, 1 employ
specially constructed duplex or compound roller or ball bearings.
Second. These roller or ball bearings are constructed in combination with a
specially formed metallic frame or sole and
Third. The ball bearings and the metallic sole or framing are constructed in
combination with special apparatus and appliances for carrying the lubricating
substance and conveying the same to the bearings and although in some instances
ball bearings may be employed, I will confine myself in the present instance to a
description of my improvements where roller bearings are employed.
The metallic sole or frame which may be cast in steel or other suitable material,
I form in two parts one for each side of the vehicle the two parts being bound or
tied together by metallic or wooden stays in a similar manner to that employed
in the construction of similar vehicles made in wood.
Each metallic frame is formed with a recess or channel on its upper side for the
greater part of its length, this channel or recess being provided as a reservoir or
receptacle for the oil or other lubricating substance, and at each end the frame is
made of box shape to form the buffers, it is also provided with joggles, brackets, or
recesses to which the body of the corve may be secured, each frame likewise is
provided with four recesses to carry the roller bearings two of which are placed
above each journal of the axle on that side of the vehicle.
The roller bearings each carry a spindle and each spindle is fitted with two
runners or discs, one at each side the frame.
The journal of the axle is placed midway between the two roller bearings and
revolves under the four runners or discs on each journal.
A hole or notch may be formed in the frame for the axle to pass through and
revolve with clearance and the axle may be prevented slipping out of place when the
vehicle is tipped by means of a cap or strap or in some cases the axle may be
passed through a hole in the frame and afterwards secured by the keying on of the
wheels.
It will thus be seen that there will be two sets or four roller bearings in each side,
two to each axle and that there will be eight revolving discs on each side, four to

bearings and sixteen runners or discs.
The recesses in the frame for the roller bearings are formed or corved out so that
when the rollers are in place with their respective spindles they cannot come
out. These recesses which carry the rollers have a hole or orifice communicating
with the oil channel or recess above them, and the flow of the oil between the
oil channel and the recesses carrying the rollers, is regulated by means of a taper or
convex slide fitted along the bottom of the channel which may be likewise either
tapered or concave. This slide is kept in position by means of a spring or springs
placed between it and the cover of the oil channel.
a
In the last named slide, holes are formed to correspond to those communicating
with the roller bearings and this slide which really forms a false bottom to the oil
channel may be worked by a suitable lever or trigger from either or both ends of
the frame and the same lever, trigger or handle may actuate the oil slides on both
sides at the same time so that all the bearings may be lubricated simultaneously.
The oil channel which may be cast or cored out in the frame close by fitting
loose cover which may be made oil tight and easily removed for examination
of the oil slides and orifices or for cleaning out. Air tubes or openings would be
provided so as to ensure the flow of the oil through the orifices to the bearings and
may likewise be utilised for filling the oil receivers. The metallic framing may be
lightened or cored out and made of a section suitable to the size and kind of vehicle
with which it is to be employed.
In some cases as for example a small corve, the side frames and stays may be all
cast in one piece. The body of a corve or other vehicle fitted with the
improvements herein described may be made either in wood or in metal or a
combination of materials may be employed.

IN COLLIERY TUBS OR CORVES AND THE LIKE TRAMWAY VEHICLES AND IN

to be particularly described and ascertained in and by the following statement :-
Although my invention is applicable to a variety of vehicles a description of it

a description of my improvements where roller bearings are employed.
The metallic sole or frame which may be east in steel or other suitable material,
I form in two parts one for each side of the vehicle the two parts being bound or
tied together by metallic or wooden stays in a similar manner to that employed in
the construction of similar vehicles made in wood.
Each metallic frame is formed with a recess or channel on its upper side for the
greater part of its length, this channel or recess being provided as a reservoir or

The roller bearings each carry a spindle and each spindle is fitted with two
runners or discs, one at each side the frame.
The journal of the axle is placed midway between the two roller bearings and
revolves under the four runners or discs on each journal.
A hole or notch may be formed in the frame for the axle to pass through and

In the last named slide, holes are formed to correspond to those communicating

channel may be worked by a suitable lever or trigger from either or both ends of
the frame and the same lever, trigger or handle may actuate the oil slides on both
sides at the same time so that all the bearings may be lubricated simultaneously.
The oil channel which may be cast or cored out in the frame 1 close by fitting a
loose cover which may be made oil-tight and easily removed for examination of the
oil slides and orifices or for cleaning out.
Air tubes or openings would be provided so as to ensure the flow of the oil through
the orifices to the bearings and may likewise be utilised for filling the oil receivers.
The metallic framing may be lightened or cored out and made of a section
suitable to the size and kind of vehicle with which it is to be employed.
In some cases, as for example, a small corve, the side frames and stays may be all
cast in one piece.
The body of a corve or other vehicle fitted with the improvements herein
described may be made either in wood or in metal or a combination of materials
may be employed.
The nature of my invention will be better understood on reference to the
accompanying sheet of drawings, in which,
Fig. 1, represents the side elevation of a corve or similar vehicle fitted with my

page_text: improved metallic frame, roller bearings, and other improve.nents as, herein
previously described.
