Year: 1874

page_text: LETTERS PATENT to Henry Carrick and John Dobson Wardale, both
of Gateshead-on-Tyne, in the County of Durham, for the Invention
of "IMPROVEMENTS IN THE CARRYING WHEELS OF REVOLVING VESSELS USED
IN VARIOUS MANUFACTURES."
Sealed the 28th August 1874, and dated the 4th March 1874.
PROVISIONAL SPECIFICATION left by the said Henry Carrick and
John Dobson Wardale at the Office of the Commissioners of Patents,
with their Petition, on the 4th March 1874.
We, HENRY CARRICK and JOHN DOBSON WARDALE, both of Gates-
5 head-on-Tyne, in the County of Durham, do hereby declare the nature
of our said Invention for "IMPROVEMENTS IN THE CARRYING WHEELS OF
REVOLVING VESSELS USED IN VARIOUS MANUFACTURES," to be as follows:-
This Invention relates to the wheels for carrying the revolving
cylinders of revolving ball furnaces, or other revolving vessels for

page_text: chemical paper or other manufacture, and consists in forming the peri-
pheries of such carrying wheels of a V shape, concave, convex, flat, or
any other suitable shape, used either simply or in combination with a
flange on each side; for the purpose of preventing the lateral motion in
the revolving cylinders caused by the carrying wheels hitherto used,
which are generally formed with parallel or conical edges having a
flange on one side only, the consequence being that the revolving
cylinder is at liberty to move endways without resistance until brought
up by the flange.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Carrick and John Dobson Wardale in the
Great Seal Patent Office on the 4th September 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
CARRICK and JOHN DOBSON WARDALE, both of Gateshead-on-Tyne, in
the County of Durham, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of March, in the year
of our Lord One thousand cight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Henry Carrick and John Dobson
Wardale, Her special license that we, the said Henry Carrick and
John Dobson Wardale, our executors, administrators, and assigns, or
such others as we, the said Henry Carrick and John Dobson Wardale,
our executors, administrators, or 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 THE CARRYING WHEELS OF REVOLVING VESSELS USED IN
VARIOUS MANUFACTURES," upon the condition (amongst others) that we,
the said Henry Carrick and John Dobson Wardale, our executors or
administrators, by an instrument in writing under our hands and scals, or
under the hand and seal of one of us, should particularly describe and

page_text: ascertain the nature of the 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Henry Carrick and John Dobson
Wardale, do hereby declare the nature of our said Invention, and
in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference
being had to the accompanying Drawings and to the letters and figures.
marked thereon, that is to say :-
This Invention relates to the wheels for carrying the revolving
cylinders of revolving ball furnaces or other revolving vessels for
chemical paper or other manufactures, and consists in forming the peri-
phery of such carrying wheels of a V shape concave, convex, flat, or
any other suitable shape, used either simply or in combination with a
flange on each side for the purpose of preventing the lateral motion in
the revolving cylinders caused by the carrying wheels hitherto used,
which are generally formed with conical edges having a flange on one
side only, the consequence being that the revolving cylinder is at liberty
to move endways without resistance until brought up by the flange.
And in order that our said Invention may be fully understood, we
shall now proceed more particularly to describe the same, and for that
purpose shall refer to the several Figures on the annexed Sheet of
Drawings, the same letters of reference indicating corresponding parts
in all the Figures.
Figure 1 represents a side clevation of the cylinder of a revolving
furnace mounted on our improved carrying wheels, and Figure 2 an end
clevation of the same.
A represents the revolving cylinder of a revolving ball furnace, the
said cylinder being encircled by the rings or hoops a, a, which are made
of cast iron, wrought irou, or other suitable material, and are secured to
the outside of the cylinder by bolts, screws, rivets, shrinking or other.
wise; B, B, are carrying wheels secured to spindles b, b, mounted in the
bearings of the plummer blocks or carriages C, C, which are arranged as
shewn beneath the cylinder A, and are bolted or otherwise secured to a

page_text: suitable bed or foundation. The sections of the peripheries of the carrying
wheels B, B, arc of a
shape with flanges on both sides, while
the peripheries of the rings or hoops a, a, are of an inverted or
shape, so as to correspond with the peripheries of the carrying wheels
B, B, on which the said rings or hoops, with the cylinder A, are carried
or revolve. By the shape thus given to the peripheries of the said
wheels and hoops all lateral movement or oscillation in the revolving
cylinder A hitherto experienced when revolving on the ordinary carrying
wheels is prevented.
The peripheries of the latter wheels are generally formed of a flat or
conical shape, with a flange on one side only, in consequence of which
the revolving cylinder has considerable play endways without resistance
until brought up by the said flange.
Figures 3, 4, 5, 7, and 8 represent sections of the peripheries of
carrying wheels, each of which peripheries is of a different shape accord-
ing to our Invention; that in Figure 3 is of an inverted
shape,
with a flange on cach side; in Figure 4, of a convex shape with double
flanges; in Figure 5 of an inverted flattened
shapo with doublo
flanges; Figure 7 shews a concave periphery with double flanges, and
Figure 8 a flattened
shape with double flanges.
In each of these cases the peripheries of the rings or hoops revolving
with the furnace upon the peripheries of the carrying wheels are of a
reversed shape so as to correspond or fit into the shape of the latter with
the view to prevent oscillation in the furnace.
The foregoing description is not confined to the revolving cylinders of
revolving ball furnaces, but is equally applicable to the carrying wheels
of any other description of revolving vessel used in various manu-
factures, neither do we bind ourselves to any particular form of revolving
vessel, nor to the application of a flange or flanges, either to the peri-
pheries of the carrying wheels or revolving rings or hoops, but what wo
do claim as the Invention secured to us by the herein-before in part
recited Letters Patent is,-
Forming the peripheries of the carrying wheels of revolving furnaces
or other vessels of a concave, convex, or other shape in combination or

page_text: not with a flange or flanges, substantially as and for the purpose herein-
before described and illustrated by our Drawings.
In witness whereof, we, the said Henry Carrick and John Dobson
Wardale, have to this our Specification set our hands and seals
this First day of September, One thousand eight hundred and
seventy-four.
