Year: 1878

page_text: LETTERS PATENT to James Taylor, of Gilroyd, Barnsley, in the County of
York, Engineer, for the Invention of "IMPROVEMENTS IN MINING CORVES AND
WAGGONS."
Sealed the 4th March 1879, in pursuance of an Order of the Lord Chancellor, and
dated the 27th August 1878.
PROVISIONAL SPECIFICATION left by the said James Taylor at the Office
of the Commissioners of Patents on the 27th August 1878.
JAMES TAYLOR, of Gilroyd, Barnsley, in the County of York, Engineer. "Iм-
PROVEMENTS IN MINING CORVES AND WAGGONS."
This Invention relates to improvements in the construction of mining corves and
waggons, in order to economize space and to obtain greater simplicity and ease in
working.
Hitherto corves as ordinarily constructed have been from 32 to 36 inches high,
thereby rendering it extremely difficult to work the same in mines where the
distance from the floor to the roof is only 3 feet, or sometimes less, as frequently
occurs. To obviate this inconvenience, I construct the corf so that it is only about
28 or 29 inches high, at the same time that its containing capacity is quite as great
as those hitherto in use. By so doing, not only is the corf much easier to fill but it
does not require so much of the roof of the mine to be brought down to allow of its
passing through.
I effect such improvements in the following manner:-I form the bottom of the
corf of a plate of malleable iron, steel, or other suitable metal, preferably cast in one
solid piece with the draw bars, pedestals, and buffers, and having suitable cavities
or recesses formed therein to permit of the wheels when placed in position pro-
jecting inside through the bottom of the corf for about one half of their diameter,
and thus partly running inside the corf.
In order to further economize space, and secure simplicity of construction and
ease in working the corf, I dispense altogether with the wheel axles, the wheels

and fastened therein by suitable metal pins or studs, and in order to allow of their
being so fastened, suitable sockets or lugs are cast about midway on cither side of
each of such cavities or recesses, or in any other convenient position, and are pro-
vided with suitable movable caps, which are affixed thereto by means of screws, or
otherwise, so as to allow of the wheels being removed from the vehiclo when
necessary.
The wheel and centre being cast in one piece, the incline pulleys for carrying the
rope can be placed much higher than ordinarily, there being no axles to interfere
therewith.
I impart increased strength to the bottom of the corf by fixing outside thereof a
broad flange made of steel, malleable iron, or other suitable metal, so as to run
all the way round the corf, the corners of which flange aro thrown up about
4 inches in order to firmly support the plates, and thus all necessity for any stay
bolts is avoided.
I also employ corner plates made of steel or any other suitable metal fitted to the
body of the corf by screws or clamps, or in any other suitable manner, so as to give
additional strength to the entire structure, and as the metal required is cast in solid
pieces and easily attached, I by this means avoid the labour and expense attendant
upon smith's work whether in fitting or otherwise.
The wheels being disconnected with each other go along the sharpest curves with
the greatest ease and freedom from oscillation when the corves are loaded with
10 cwts. each.
It is obvious that if the corf be constructed of the ordinary height (viz. about
36 inches) its containing capacity will be considerably in excess of those at present
in use.
I would here remark that the bottom of the corf may, if preferred, be constructed
of several sheets of metal instead of one solid cast sheet, and that the only wood-
work therein is the inch boarding formning the sides thereof.
My improved corf is not only simple in construction but possesses great strength
owing to the steel bands and plates, and the firmness with which the various parts
are put together, and its durability will be at least four times greater than that
of an ordinary corf owing to its ease in running and non-liability to get out of
repair.

the said James Taylor in the Great Seal Patent Office on the 4th March
1870.
JAMES TAYLOR, of Gilroyd, Barnsley, in the County of York, Engineer. “Iм-
PROVEMENTS IN MINING CORVES AND WAGGONS."
↑ This Invention relates to improvements in the construction of mining corves and
waggons, and has for its object not only to economize space but to obtain greater
simplicity of construction and increased facility in working the corf or waggon.
Hitherto corves as ordinarily constructed have been from 32 to 36 inches high,
thereby rendering it extremely difficult to work the same in mines where the
distance from the floor to the roof is only 3 feet, or sometimes less, as frequently
occurs. To obviate this inconvenience, I construct the corf so that it is only about
28 or 29 inches high, at the same time that its containing capacity is quite as great
as those hitherto in use. One great advantage obtained by such construction is
that by so doing not only is the corf much easier to fill but it does not require so
much of the roof of the mine to be brought down to allow of its passing through.
And in order that my said Invention may be botter understood, I will now with
the aid of the accompanying Drawings proceed to more particularly describe the
same.
Figure 1 of such Drawings shews a plan view of the underside of the metal plate
forming the bottom of one of my improved corves or waggons; Figure 2 is a view
in side elevation of one of such corves or waggons shewing the flange and corner
plates hereafter described; and Figure 3 shows a view of the wheel of the corf.
I effect such improvements in the following manner :-I form the bottom of the
corf of a plate a of malleable iron, steel, or any other suitable metal (preferably cast
in one solid pieco with the draw bars, pedestals, and buffers), and having suitable
cavities or recesses 6 formed therein to permit of the wheels when placed in posi-
tion projecting inside through the bottom of the corf for about one half of their
diameter, and thus partly running inside the corf. If preferred, however, the
bottom of the corf may be constructed of several sheets of wrought or cast metal
instead of one solid cast sheet.
Another feature of my Invention relates to an improved corf wheel, which I
effect as follows:-In order to further economize space, and secure simplicity of
construction and ease in working the corf, I dispense altogether with the wheel
axles, the wheels being fixed independently of each other in the recesses or cavities b
before mentioned, and fastened therein by suitable metal pins or studs, and in order
to allow of their being so fastened, suitable sockets or lugs c are cast about midway
on either side of cach of such cavities or recesses, or in any other convenient posi-
tion, and are provided with suitable movable caps d which are affixed theroto by
means of screws or otherwise, so as to allow of the wheels being removed from tho
vehicle when necessary.
The wheel and centre are cast in one piece, of the form shewn in Figure 3, and
owing to this the incline pulleys for carrying the rope can be placed much higher
than ordinarily, there being no axles to interfere therewith.
The advantage and novelty of my improved corf wheels consist,-
Firstly. In the simplicity of moulding without boring, while the centre is
properly true and round without turning.
Secondly. Owing to their being made taper they sit in the pedestal and thus
allow, say, one third of the diameter to project beyond the top of the pedestal, so
that the patent revolving greasing apparatus can just grease the larger diameter of
the centre or axle (indicated by the arrow in Figure 3) as it runs over the greaser,
and yet allow the head of the set screw to catch on or project partially over the
smaller ends so as to prevent the wheel dropping out of its place, as also illustrated
in Figure 3 of the accompanying Drawings

page_text: By dispensing with boring and turning a considerable diminution in the cost of
manufacture is effected.
I impart increased strength to the bottom of the corf by fixing outside thereof a
broad flange e mado of steel, malleable iron, or any other suitable metal, so as to
run all the way round the corf, the corners of which flange are thrown up about
4 inches, as indicated at c¹, in order to firmly support the plates, and thus all
necessity for any stay bolts is avoided.
I also employ corner plates f made of steel or any other suitable metal fitted to
the body of the corf by bolts or clamps or in any other suitable manner, so as to
give additional strength to the entire structure, and as the metal required is cast in
solid pieces and easily attached, I by this means avoid the labour and expense
attendant upon smith's work whether in fitting or otherwise.
It is obvious that if the corf be constructed upon my improved principles of the
ordinary height (viz., about 36 inches), its containing capacity will be considerably
in excess of those at present in use.
One advantage possessed by corves constructed upon my improved principles is
that the wheels being disconnected with each other go along the sharpest curves
with the greatest ease, and with entire freedom from oscillation when the corves
are heavily loaded with coal or other material.
I would here remark that the only woodwork employed in the construction of
my improved corf is the boarding forming the sides thereof, indicated at g,
Figure 2.
Such improved corf is not only simple in construction but possesses great
strength owing to the steel flanges or bands and plates, and the firmness with
which the various parts are put together, and its durability and consequent
economy will be found to be at least four times greater than that of an ordinary
corf owing to its easy running and non-liability to get out of repair.
I would observe that if preferred my improved corf may be made without the
wheels projecting inwards partially in the bottom plate, as before described.
Having now particularly described and ascertained the nature of my said
Invention, I would have it understood that I claim as my Invention,―
1°. The improved construction of mining corves and waggons, substantially as
herein-before set forth and illustrated by the accompanying Drawings.
20. The improved construction of wheel and method of fitting the same, as
herein-before described and illustrated.
In witness whereof, I, the said James Taylor, have hereunto set my hand and
seal, this Twenty-eighth day of February, in the year of our Lord One
thousand eight hundred and seventy-nine.
JAMES TAYLOR. (L.S.)
