"IMPROVEMENTS IN THE CONSTRUCTION OF APPARATUS FOR LUBRICATING THE
AXLES OF COLLIERY TUBS."
This Invention consists in improvements in the construction of apparatus for
lubricating the axles of colliery tubs, whereby that operation is performed in a
more simple and efficaceous manner than by the apparatus hitherto employed, whilst
at the same time a great saving in the amount of lubricating material used is
effected.
An axle mounted in suitable bearings is provided at each end with a pair of
wrought-iron discs, and between the discs forming each pair is a disc of india-rubber
or other suitable material possessing the requisite degree of elasticity and pliability,
the diameter of the last-mentioned discs being greater than that of the wrought-iron
discs.. The projecting edges of the elastic discs are provided with teeth having
spaces of a semicircular or other suitable form between them. On the axle and in
the space between the before-mentioned pairs of discs is mounted a metal wheel or
disc also provided with teeth.
The whole of the apparatus before described is mounted in a receptacle which is
sunk between the rails on which the tubs run to such a depth as to allow of the
teeth on the peripheries of the before-mentioned india-rubber discs and centre metal
wheel being acted upon by the axles of the tubs when the latter pass over the
same.
The receptacle is divided into separate portions, two of such portions serving as
reservoirs for the lubricating material, so that the lower portions of the india-rubber

page_text: discs passing through the same take up in the spaces between the teeth thereof a
portion of the lubricating material, whilst the centre metal wheel or disc works in a
clear space.
The action of the apparatus is as follows:-On a tub passing over the same the
axle of the tub takes into the spaces between the teeth on the peripheries of the
india-rubber discs, and takes up the lubricant contained therein, the axles of the
tubs being so arranged that the straps or other contrivances by which the same are
attached pass at the side and entirely free of the india-rubber discs. As the axle
comes in contact with the india-rubber discs it also acts upon the centre wheel or
disc, and causes the axle on which the discs are mounted to partially rotate, thus
presenting other lubricating spaces to the next tub axle.
When it is desired to remove one of the india-rubber discs the bolts which hold
together the pair, of wrought-iron discs containing the samé are unscrewed, and the
outer disc slipped off the axle, when the india-rubber disc can also be taken off
and cleaned, repaired, or another one substituted, as may be desired.
The-before-mentioned receptacle is provided with a cover to prevent as far as
possible the entrance of dust and dirt to the reservoirs and other parts of the
apparatus.
The lubricant employed, as before described, should be of such a consistency as to
ensure its always possessing a level surface, and of preserving the same notwith-
standing the action of the india-rubber discs.
It is manifest that this Invention can be applied to and used in connection with
vehicles other than colliery tubs.
The advantages of the apparatus constructed, as before described, is that it pos-
sesses great simplicity, is very efficaceous in its action, economical in the use of the
lubricating material, strong, and not liable to get out of order, and can be readily
cleaned or repaired.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said John Hallimond in the Great Seal Patent Office on the 30th
November 1877.

JOHN HALLIMOND, of Escomb, near Bishop Auckland, in the County of Durham.
'IMPROVEMENTS IN THE CONSTRUCTION OF APPARATUS FOR LUBRICATING THE
AXLES OF COLLIERY TUBS."
My said Invention consists in improvements in the construction of apparatus for
lubricating the axles of colliery tubs, whereby that operation is performed-in-a-more
_simple.and-efficaceous-manner than by the apparatus hitherto employed for that
purpose, whilst at the same time a great saving in the amount of lubricating material
used is effected.
An axle is mounted in suitable bearings, the same being provided at each end
-with-a-pair of wrought-iron.discs. Between the discs forming each pair is a disc-of
-india-rubber, leather,-or-other-suitable material possessing the requisite degree of
elasticity and pliability, the diameter of the last-mentioned discs being greater than
that of the wrought-iron discs. The projecting edges of the elastic discs are provided
with teeth having spaces of a semicircular or other suitable form between them. On
the axle and in the space between the before-mentioned pairs of discs is mounted a
metal wheel or disc also provided with teeth.

page_text: The whole of the apparatus before described is mounted in a receptacle which is
sunk between the rails on which the tubs run to such a depth as to allow of the
teeth on the peripheries of the before-mentioned elastic discs and centre metal
wheel being acted upon by the axles of the tubs when the latter pass over the
same.
The receptacle is divided into separate portions, two of such portions serving as
reservoirs for the lubricating material, so that the lower portions of the elastic discs,
in passing through the same, take up in the spaces between the teeth thereof a
portion of the lubricating material, whilst the centre metal wheel or disc works in
a clear space.
The action of the apparatus is as follows:-On a tub passing over the same the
axle of the tub takes into the spaces between the teeth on the peripheries of the
elastic discs, and takes up the lubricant contained therein, the axles of the tubs
being so arranged that the straps or other contrivances by which the same are
attached pass at the side and entirely free of the elastic discs. As the axle comes in
contact with the elastic discs it also acts upon the centre wheel or disc, and causes
the axle on which the discs are mounted to partially rotate, thus presenting other
lubricating spaces to the next tub axle.
When it is desired to remove one of the india-rubber discs the bolts which hold
together the pair of wrought-iron discs containing the same are unscrewed, and the
outer disc slipped off the axle, when the elastic disc can also be taken off, and
cleaned, repaired, or another one substituted, as may be desired.
The before-mentioned receptacle is provided with a cover to prevent as far as
possible the entrance of dust and dirt to the reservoirs and other parts of the
apparatus.
The lubricant employed, as before described, should be of such a consistency as to
ensure its always possessing a level surface, and of preserving the same, notwith-
standing the action of the india-rubber discs.
It is manifest that my said Invention can be applied to and be used in connection
with vehicles other than colliery tubs.
The advantages of the apparatus constructed as before described are that it
possesses great simplicity, is very efficaceous in its action, economical in the use of
the lubricating material, strong, and not liable to get out of order, and can be readily
cleaned or repaired.
Having thus declared and ascertained the nature of my said Invention, and in
what manner the same is to be performed, I would observe in conclusion that what
I consider novel and original and therefore claim as constituting the Invention
secured to me by the said herein-before in part recited Letters Patent is, the com-
bination and arrangement of parts and mechanism in the construction of apparatus
for lubricating the axles of colliery tubs, substantially as herein-before described and
set forth.
In witness whereof, I, the said John Hallimond, have hereunto set my hand
and seal, this Twenty-seventh day of November, in the year of our Lord
JOHN HALLIMOND. (Ls.)
