Year: 1874

page_text: LETTERS PATENT to Arthur Gilbertson, of Pontardawe, near Swansea,
and Ebenezer Gething, William Gething, and David Jenkins, of
Aberdulais, near Neath, all in the County of Glamorgan, for the
Invention of "IMPROVEMENTS IN CLEANING, FINISHING, AND COMPLETING
PRATS DWT on Than
Sealed the 16th March 1875, and dated the 28th September 1874.
PROVISIONAL SPECIFICATION left by the said Arthur Gilbertson,
Ebenezer Gething, William Gething, and David Jenkins at the
Office of the Commissioners of Patents, with their Petition, on the
28th September 1874.
We, ARTHUR GILBERTSON, of Pontardawe, near Swansea, and
EBENEZER GETHING, WILLIAM GETHING, and DAVID JENKINS, of
Aberdulais, near Neath, all in the County of Glamorgan, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN CLEANING,
FINISHING, AND COMPLETING PLATES COATED WITH TIN OR TERNE, AND IN
APPARATUS THEREFOR," to be as follows:-
According to the ordinary mode of cleaning, finishing, and completing
sheets or plates coated with tin or terne the sheets or plates are taken by

page_text: women, and cleaned by hand, and passed through several sets of troughs,
causing much time and labour, and involving the use of much bran and
sheep skins.
Now, according to this Invention, the same or an improved result is
obtained by the mode and means or machinery hercin-after described,
whereby a great economy in time, labour, and materials employed is
attained.
Machinery constructed according to this Invention consists of a
system of rollers and parts connected therewith arranged in or on
framework, the said rollers revolving at different speeds, and at different
pressures attained by adjustable springs, or equivalent means, and being
connected by tooth wheels, straps, or other suitable gearing. The power
required is obtained from the usual tin set engine, or any other suitable
or convenient motor.
In the usual way of working our apparatus the plates are by an
attendant employed at one or more tin or terne sets placed into or on a
revolving wheel, rack, or other suitable mechanical delivery apparatus,
which forwards the plates to a sliding table or endless band, or other
suitable appliance, which delivers them to the nip of the first set of
rollers (or the plates might be fed to the said rollers by hand, but we
prefer the first-named mode and means). The plates are then caught by
cach succeeding set of rollers, and passed through guides which may be
supplied with a polishing material. We also keep some of the rollers
covered with a polishing material, and bran or other suitable cleansing
substance is supplied to some of the rollers, the quantities being regu-
lated by a handle or handles accessible to the attendant.
By the use of rollers, as aforesaid, the contingent advantage is
obtained that the plates are freed from being bulged or puckered.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Arthur Gilbertson, Ebenezer Gething, William &
Gething, and David Jenkins in the Great Seal Patent Office on the
27th March 1875.

in the County of Glamorgan, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of September, in the
year of our Lord One thousand cight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Arthur Gilbertson, Ebenezer
Gething, William Gething, and David Jenkins, Her special licence that
we, the said Arthur Gilbertson, Ebenezer Gething, William Gething,
and David Jenkins, our executors, administrators, and assigns, or such
others as we, the said Arthur Gilbertson, Ebenezer Gething, William
Gething, and David Jenkins, our executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and
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 CLEANING, FINISHING, AND
COMPLETING PLATES COATED WITH TIN OR TERNE, AND IN APPARATUS THEREFOR,"
upon the condition (amongst others) that we, the said Arthur Gil-
bertson, Ebenezer Gething, William Gething, and David Jenkins, our
executors or administrators, by an instrument in writing under our or
one of our or their hands and seals, should particularly describe and
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 Arthur Gilbertson, Ebenezer
Gething, William Gething, and David Jenkins, do hereby declare the
nature of our said Invention, and in what manner the samo 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 of reference marked thereon, that is to say :-
According to the ordinary mode of cleaning, finishing, and completing
sheets or plates coated with tin or terne the sheets or plates are taken
by women, and cleaned by hand, and passed through several sets of
troughs, causing much time and labour, and involving the use of much
bran and sheep skins,

page_text: intermediate shaft c that again derives motion by gut and grooved
pulleys from the spindle of the lower roller E¹ of the first set of cleaning
or polishing rollers E, E'. From the wheel rack C the plates are passed
automatically to an endless band D, which may be of leather that is
kept on the stretch by a bell-crank lever and weight, as shown: B, B,
are side guides between which the plate passes on to the first set of
rollers E, E, thence through a guide, which is here made in the shape
of a box F, containing bran or other cleaning or polishing material,
which is thus supplied to both sides of the plate, and is rubbed over it
through a reciprocating movement imparted to the box F by a rod f¹
from an eccentric fon the main driving shaft I of the apparatus, which
shaft obtains its motion by strap or gearing from the tin set machine or
other motor.
The bran comes on to the upper side of the plate by its own weight,
but is pressed on to the lower side of the plate by a spring or springs
operating against a false bottom F' in the lower part of the guide or
box F, which has guide bars G for guiding the plates in their passage
from one set of rolls to the other. The edges of the guides or boxes,
where the plates pass through, may be covered with sheep skin, leather,
or india-rubber. The bran, after having been used, falls into shoots or
troughs L of tin plate or other material. The rollers E, E¹, of which
four sets are shown in this case, derive revolving motion by bevel
wheels e on the shaft I gearing into corresponding bevel wheels e¹ on the
spindles of the lower rollers E¹, which again by spur pinions communi-
cate revolving motion, but at a different speed to spur wheel S on the
upper rollers E; the plates are thus exposed to rubbing action, partly
by reason of the unequal speed of the rollers, and partly by reason of
the side movement of the guides F. The first roller E¹ has a weighted
scraper K for removing the dirt.
The rollers may be covered with leather, sheep skin, india-rubber, or
similar polishing material, or be of plain wood.
From the first set of rollers and the following guide F, G, the plate is
conveyed to the next or second set of rolls, which pass it through the
second guide F, G, to the third set of rolls, which again push it through
two pieces of sheep skin H, which are secured to two pieces of wood,
and finally to the last set of rolls, which deliver the plate on to a table M,
an attendant removing it, and finally, if required, dusting it with sheep
skin or other material.

page_text: The pressure on the rollers E, E', is regulated by means of the
springs n and regulating screws m.
And having thus fully described this Invention, wo declare that we
claim,―
Firstly. The mode of cleaning, polishing, and dusting tin and terne t
plates by machinery operating substantially as herein set forth.
Secondly. The general combination of machinery, consisting of sets of
rollers working at different speeds, and under adjustable pressure in com-
bination with guides placed between the sets of rollers, and supplied with
bran, or other polishing material, substantially as and for the purpose 1
set forth.
Thirdly. The rollers E, E, constructed and operating as and for the
purpose described.
Fourthly. The guides F, G, with the means for applying and rubbing
the polishing material on to both sides of the plates.
Fifthly. The rack wheel C, in combination with an endless band D
and guides B, for delivering the plates to the first set of rollers..
In witness whereof, I, the said Arthur Gilbertson, for myself and
on behalf of the said Ebenezer Gething, William Gething, and
David Jenkins, have hereunto set my hand and seal, this
Twenty-fourth day of March, in the year of our Lord One
thousand eight hundred and seventy-five.
