We THOMAS COLQUHOUN of West Stanley Colliery, R.S.O. County of Durham
Mining Engineer, and JAMES ALLAN THOMPSON of West Stanley Colliery, R.S.O.
County of Durham, Colliery Engineer do hereby declare the nature of this invention
to be as follows:-
Our invention relates to improvements in the method of applying grease or other
lubricant to the axles of Colliery tubs and similar vehicles which cannot conveniently
be fitted with ordinary grease boxes or lubricators.
The ordinary methods of lubricating such axles either consist in applying the
grease direct to the axles with a brush or dab-stick when the tub is upturned in the
kick-up" or by means of wheels, revolving in a trough containing the lubricant
over which wheels the axles pass and by contact receive a charge.
Other methods have been tried by which the lubricant is contained in a reservoir
forming part of the axle bearing but none of these have proved successful in actual
working.
"
According to our invention the lubricant is contained in boxes inside the tub, one
over the bearing of each axle, secured preferably by bolts which also secure the
"train
to bottom of tub, the "cod" to the train and the strap to the "cod" and
these boxes are fitted with a cover to protect them from injury by the coals falling
into the tub and means by which they can be replenished and then closed against
being tampered with.
From each box a channel leads down through the bottom of tub, the train and the
"cod" on to the axle bearing and the lower portion of this channel we prefer to make
of an oblong shape and disposed diagonally to the axis of the axle so as to distribute
the lubricant equally along the length of the bearing.
When the tub is in motion the axles receive a constant supply of lubricant which
supply ceases when they come to rest or when upturned in the "kick up," thus there
is no waste and in actual work one charging of the boxes has been found sufficient
for a very long period of working.
The time and labour required to apply grease by band with the serious waste
involved are thus entirely avoided.

We THOMAS (OLQUHOUN of West Stanley Colliory in the County of Durham,
Colliery Manager and JAMES ALLAN THOMPSON of the same place Engineer do
hereby declare the nature of our said invention and in what manner the same is to
he performed to be particularly described and ascertained in and by the following
statement:
Our invention relates to improvements in the inathod of appplying grease or other
lubricant to the axles of colliery and similar vehicles which cannot conveniently be
Gitted with onlinary grease boxes or lubricators.
The ordinary methods of lubricating such axles either consist in applying the
grease direct to the axles with a brush or al-stick when the tub is upturned in the
"kick up or by means of wheels, revolving in a trough containing the lubricant
over which wheels the axles pass and by contact receive a charge. Other methods
have been tried by which the lubricant is contained in a reservoir forming part
of the axle bearing but none of these have proved successful in actual working.

and
According to our invention the lubricant is contained in boxes inside the tub, one
over the bearing of each axle, secured preferably by bolts which also secure the
tram to bottom of tub, the "cod" to the tram and the strap to the "cod
these boxes are fitted with a cover to protect them from injury by the coals falling
into the tub and means by which they can be replenished and then closed against
being tampered with.
From each box a channel leads down through the bottom of tub, the tram and
the "cod" on to the axle bearing and the lower portion of this channel we prefer to
make of an oblong shapo and disposed diagonally to the axis of the axle so as to
distribute the lubricant equally along the length of the bearing.
When the tub is in motion the axles receive a constant supply of lubricant which
supply coases when they come to rest or when upturned in the "kick-up" thus there
is no waste and in actual work one charging of the boxes has been found sufficient
for a very long period of working. The time and labour required to apply grease by
hand with the serious waste involved are thus entirely avoided.

page_text: A is the axle running in the half bearing or "Cod" B which is bolted to the
"tram" by the bolts C, the same bolts taking the flanges of the lubricant box D
in which is a cavity to receive the lubricant covered by a hinged lid E secured
by a nut F on a fixed bolt G. From the bottom of the cavity a round channel H
passes through the box D, the bottom of tub and the "tram" frame after which
it becomes an oblong channel passing through the "Cod" B and opening on top
of axle A at an angle so as to cause the lubricant to be distributed along the
bearing. At the junction between the round and oblong channels a shallow cavity
may be formed in the top side of the "Cod" as shewn to receive the lubricant
on its way to the axle but this is not an important feature.
When the tub is running the lubricant is continuously and regularly supplied
to the axle A from the cavity through the channel H but when at rest or when
upturned to discharge the supply at once ceases. The lubricant is supplied when
the tub is empty by unscrewing the nut F and turning back the lid. The lid
may instead of being hinged be screwed into the cavity by a suitable wrench key
or may be secured in any other way which will prevent it being mischievously
removed.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is-
For lubricating the axles of colliery tubs and similar vehicles the application of
receptacles for the lubricant placed within the tub or similar vehicle over each of
the journals and communicating therewith by channels so disposed as to supply the
lubricant continuously only whilst the axles are revolving, and thus to prevent waste;
Substantially as described and shown.
