IMPROVEMENTS IN APPARATUS FOR LUBRICATING THE AXLES 6 OF COLLIERY CORVES' OR 'TUBS' WHEN IN MOTION
Year: 1870

page_text: LETTERS PATENT to Wilfred Creswick, of Rotherwood, in the Parish
of Rotherham, in the County of York, Mining Engineer, for the
Invention of "IMPROVEMENTS IN APPARATUS FOR LUBRICATING THE AXLES
6
OF COLLIERY CORVES' OR 'TUBS' WHEN IN MOTION."
Sealed the 11th January 1871, and dated the 21st July 1870.
PROVISIONAL SPECIFICATION left by the said Wilfred Creswick at
the Office of the Commissioners of Patents, with his Petition, on
the 21st July 1870.
I, WILFRED CRESWICK, of Rotherwood, in the Parish of Rotherham,
in the County of York, Mining Engineer, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN APPARATUS FOR LUBRICATING
THE AXLES OF COLLIERY CORVES' OR TUBS' WHEN IN MOTION," to be as
follows:-
This Invention consists mainly of a bush in which the axle works
as heretofore, together with a cast metal or cast malleable iron box or
receptacle to contain grease to lubricate the axle. This box is intended

page_text: to be fixed or secured on to the "sole" " piece" or "leg," or on any
other suitable place on the corf or tub, and the grease is supplied to
the axle by the force of gravity and percussion through a hole or opening
in the box communicating with the axle, and thus effecting the lubrica-
tion when the corves or tubs are in motion. This box is filled with
grease by means of an opening at the top, which latter opening is
intended to be closed by a spring.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Wilfred Creswick in the Great Seal Patent Office
on the 20th January 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILFRED
CRESWICK, of Rotherwood, in the Parish of Rotherham, in the County
of York, Mining Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of July, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-fourth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Wilfred Creswick, Her special licence that I,
the said Wilfred Creswick, my executors, administrators, and assigns, or
such others as I, the said Wilfred Creswick, my executors, adminis-
trators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS FOR
LUBRICATING THE AXLES OF COLLIERY * CORVES' OR 'TUES WHEN IN MOTION,"
upon the condition (amongst others) that I, the said Wilfred Cres-
wick, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of my said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
.
'
NOW KNOW YE, that I, the said Wilfred Creswick, do hereby declare
the nature of ny said Invention, and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by the
following statement in writing, and on reference being had to the accom-
panying Sheet of Drawings, that is to say:-
This Invention consists mainly of a bush in which the axle works
as heretofore, together with a box or receptacle of either cast metal or
malleable cast iron to contain grease to lubricate the axles.
The Invention will be readily understood by the following explana-
tion, and on reference to the accompanying Sheet of Drawings, on which
Figure 1 represents a plan view, and Figure 2'a front elevation of the
improved apparatus, the cover of the box being removed; Figure 3
represents a section through the line, A, B, Figure 1; Figure 4 shews.
a plan view of the cover of the box; and Figure 5 a side view of the
same.

The box 4 is fixed or secured on the sole piece or leg," or other
suitable place on the corf or tub, and the grease is supplied to the axle
by the forces of gravity and percussion through the hole or opening 12.
in the box communicating with the axle, and thus effecting the lubri-
cation when the corves or tubs are in motion. To prevent as much as
possible any irregularity in the greasing through the variation in the
consistency of the grease used, I insert (when required) in the hole or
opening 12 (communicating with the axle) a perforated plug 13 of copper
or brass, or other good conductor of heat, which on becoming heated by
friction will compensate for the variation by communicating the heat to
the grease, and so tend to liquify the same. The opening 9 through
which the grease is to be supplied to the box may either be in the top
(as shown in the Drawings annexed) or in the side of the box as con-
venience suits, and this opening is intended to be closed by a spring 10
(as shewn in Figure 4), which is rivetted at one end to the cover 8 of
the box, by the rivet 7 which passes through the hole 6. On this rivet 7
the spring is only at liberty to turn laterally. On each side of this
opening 9 studs, lugs, or projections 11 are formed so that when the
spring is in its place (as in Figure 4) it cannot be moved without first
being lifted off the face of the cover 8 of the box.
1 represents the part of the bush which rests on the upper portion
of the axle; 2, the holes through which bolts are passed to fasten the
bush to the sole piece; 3, a neck connecting the box 4 which contains
the grease with the hole 12; and 5, holes through which bolts are passed
to fasten together the box and its cover 8.

page_text: Having now particularly described the nature and object of my said
Invention for "Improvements in Apparatus for Lubricating the Axles of
Colliery Corves or Tubs when in Motion," together with the manner
in which the same is to be or may be performed or carried into practical
effect, I would remark in conclusion that I claim as my Invention, the
improved apparatus for lubricating the axles of 'colliery corves or tubs
when in motion, substantially as herein-before described and as illus-
trated on the accompanying Sheet of Drawings, or any modification
thereof operating in substantially the same or a similar manner.
In witness whereof, I, the said Wilfred Creswick, have hereunto :
set my.
hand and seal, this Eighteenth day of January, in the
year of our Lord One thousand eight hundred and seventy-one.
