PROVISIONAL SPECIFICATION left by the said Edward Kenworthy Dutton
at the Office of the Commissioners of Patents, with his Petition,
on the 5th April 1864.
I, EDWARD KENWORTHY DUTTON, of Sale, in the County of Chester,
Mechanical Engineer, do hereby declare the nature of the said Invention
for "CERTAIN IMPROVEMENTS IN APPARATUS FOR COATING OR COVERING THE SUR-
FACES OF KOLLERS OR CYLINDERS WITH LEATHER OR OTHER MATERIALS," to be as
follows:
"cotton
The apparatus is designed to cover the exterior surface of rollers or
cylinders with leather, or other similar required material, and is appli-
cable to the covering of rollers used in machines known as
gins," and more particularly to that description called the "Macarthy
gin," in which the rollers are covered with leather, wound spirally round
the roller.
The apparatus consists of two standards or supports for carrying the
roller to be covered, the journals of the roller revolving in bearings in
the top of the standards, an arrangement being made for readily insert-

the standards, or on the bed plate of the machine, and is caused by
means of screws, and bevil gearing, or otherwise, to slide to and from
the roller and parallel with the surface thereof. On this bar a carriage
slides carrying two rollers, one with its axis parallel to the roller to be
covered to press the leather on to the surface of the roller, the other
with its axis at right angles to the former to press the coils of leather
against each other, the pressure of the first-named roller being effected
by means of a handle or weighted lever on the shaft actuating the
slide bar, the resistance of the carriage as it slides on the bar affording
sufficient pressure to force the coils of leather together. The glue or
cement by which the leather is caused to adhere, may either be applied
to the leather or to the roller by hand or by self-acting means.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Kenworthy Dutton in the Great Seal Patent
Office on the 5th October 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
KENWORTHY DUTTON, of Sale, in the County of Chester, Mechanical
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of April, in the year of our Lord One
thousand eight hundred and sixty-four, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Edward Kenworthy Dutton, Her special license that I, the said
Edward Kenworthy Dutton, my executors, administrators, and assigns,
or such others as I, the said Edward Kenworthy Dutton, my executors,
administrators, 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 "CERTAIN IMPROVEMENTS IN
APPARATUS FOR COATING OR COVERING THE SURFACES OF ROLLERS OR CYLINDER'S
WITH LEATHER OR OTHER MATERIALS," upon the condition (amongst others) that
I, the said Edward Kenworthy Dutton, 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 the

page_text: 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 Edward Kenworthy Dutton, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement and accompanying Drawings (that is
to say):-
i
The apparatus is designed to cover the exterior surface of rollers or
cylinders with leather or other similar required material, and is appli-
cable to the covering of rollers used in machines known as "cotton gins,"
and more particularly to that description called the "Macarthy gin,"
in which the rollers are covered with leather wound spirally round the
roller.
The apparatus consists of two standards or supports for carrying the
roller to be covered, the journals of the roller revolving in bearings in
the top of the standards, an arrangement being made for readily insert-
ing and removing the roller therefrom. A planed bar is mounted on
the standards, or on the bed plate of the machine, and is caused by
means of screws and bevil gearing, or otherwise to slide to-and-from the
roller, and parallel with the surface thereof. On this bar a carriage
slides carrying two rollers, one with its axis parallel to the roller to be
covered to press the leather on to the surface of the roller, the other
with its axis at right angles to the former to press the coils of leather
against each other, the pressure of the first-named roller being effected
by means of a handle or weighted lever on the shaft actuating the slide
bar, the resistance of the carriage as it slides on the bar affording suffi-
cient pressure to force the coils of leather together. The gum or cement
by which the leather is caused to adhere may either be applied to the
leather or to the roller by hand or by self-acting means.
In order that the Invention may be better understood and explained
in detail, I have hereunto attached a Sheet of Drawings, made upon a
scale of about half the actual size, similar letters of reference being
marked upcu corresponding parts of the apparatus.
Referring to the Drawings Fig. 1 is a front view of the machine, shew-
ing the roller A, of the description used in the "Macarthy cotton gin,"
in process of being covered; Figs. 2 and 3 are end views, taken from
opposite ends of the machine; Fig. 4 is a plan of the carriage fitted with

page_text: the "bowls," for giving the pressure to the leather as it is laid on the
roller to be covered, and Figs. 5 and 6 are plans of a method of obtain-
ing the pressure with a different arrangement to what is shewn in the
other views.
In the several Figures the framing of the machine consists of two
standards a, a, bolted on a plate b, the upper end of each of the
standards is formed into a bearing, a portion of the which cis hinged at d,
so as to be thrown back for the introduction of the roller journals, being
afterwards secured by the screw e. The bar is fitted to slide on pro-
jecting portions of the standards, and is kept parallel to the roller to
be covered, by the racks g, g, working into the pinions h, h, on the
shaft i, and is moved towards or from the said roller by turning the
shaft. The bar f is a little longer than the roller to be covered, and
is planed from end to end, so that the sliding piece or carriage k, shewn
detached in Fig. 4, may slide freely thereon. The said carriage is pro-
vided with two "bowls" and m, the strip of leather s, which is to be
attached to the roller passing over the "bowls" m, which presses the
strip of leather to the surface of the roller, at the same time that the
bowl" presses the strip sideways against the coils of leather already
wound on to the roller by the revolution of the roller on its axis, effected
by the gearing and handle i, the surface of the roller or the strip of
leather being supplied with a suitable cement at the same time. The
pressure of the "bowls" m against the leather is given by the weighted
lever n acting on the ratchet wheel p, on the end of the shaft i, through
the "pawl" o, and forcing the bar f towards the roller, the side pressure
of the "bowl" being due to the force required to cause the carriage k
to slide on to the bar as it is pushed forward by the successive coils of
leather. The "bowl" is adjusted to the varying thickness of the coils
of leather by means of the screw q. In Figs. 5 and 6, the bar f is moved
by screws, its parallelism being maintained by connecting the screws
with bevil wheels and a cross shaft r.
Having now described the nature of the said Invention, together with
the method of carrying the same into practical effect, I wish it to be dis-
tinctly understood that I claim,―
First, the employment and use of two rollers, discs, fingers, or press-
ing surfaces to act upon the leather, (or material with which the roller
is to be covered,) at such relative angles to each other that the action of
one shall press the leather on to the roller, and the other shall simul-
taneously press the strips against each other.

page_text: Secondly, the general arrangement and construction of the apparatus,
and the method of obtaining the double pressure, with one weight or
power, as herein-before described, set forth, and fully illustrated in the
Drawings attached.
In witness whereof, I, the said Edward Kenworthy Dutton, have
hereunto set my hand and seal, this Fourth day of October, in the
year of our Lord One thousand eight hundred and sixty-four.
EDWARD K. DUTTON. (L.S.)
