PROVISIONAL SPECIFICATION left by the said John Gedge at the Office
of the Commissioners of Patents, with his Petition, on the 22nd January
1855.
I, JOHN GEDGE, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN LAMINATING METALS, EITHER IN RELIEF OR BAS-RELIEF," (a
communication,) to be as follows:-
The difficulty hitherto experienced in laminating metals in relief is, that as
only few designs can be placed on a pair of laminators, it becomes necessary.
to use a great number of cylinders. I propose to obviate this inconvenience
by using but one pair of cylinders. On one cylinder I place collars and rundles
(rondelles).. The cylinder being turned true, a groove is cut therein in order
to let in a little square or pin, and a raised channel or reeding is made so as to
cut the cylinder, as it were, into two unequal parts. Near the extremity of each
of the cylinder faces are pierced several holes to receive a small puppet screw,
which projects! In fabricating flat iron, brass, or steel, printed or impressed
only on one side, I propose to take two cylinders. On the first will be placed
a-sufficient number of rundles (plain surfaces) made of tempered iron or steel;

page_text: A
this cylinder thus becomes a laminator with collars, when five rundels may
be seen on the right of the channel, and four on the left, which are firmly
joined the one to the other, while those on the left of the cylinder are not yet
attached to each other, although they are so before being brought finally into
operation, so as to make but two tables right and left of the reeding or raised
channel. The screw heads and pins aforesaid keep keep the collars, &c. in
their exact places, so forming, as it were, a laminating mass. Rundles are also
placed on the second cylinder; these are to be engraved with the designs
sought to be obtained, and this becomes also a laminator. Thus, a pair of
laminators will be found capable of laminating iron, copper, steel, or other
metal, and impress or print on one side only. I propose also to place on the
second cylinder a rundle with the name, &c. of the Inventor, by which the
laminated metal will bear such impress. I propose to carry the operation of
my Invention somewhat modified to manufacture sheet metal with designs in
relief or bas relief.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Gedge in the Great Seal Patent. Office on the
17th July 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GEDGE, of No. 4, Wellington Street South, Strand, in the County of Middle-
sex, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent,. bearing. date the Twenty-second day of January, in the year of our
Lord One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Gedge, Her special licence that I, the said John Gedge, my executors,
administrators, and assigns, or such others as I, the said John Gedge, 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 "IMPROVEMENTS IN LAMINATING METALS, EITHER IN
RELIEF OR BAS-RELIEF," a communication from Messieurs Tournel, Frérs,
of Saint Chamond, in the Empire of France, upon the condition (amongst
others) that I, the said John Gedge, by an instrument in writing under my
hand and seal, 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 John Gedge, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying Sheet of Drawings, and
to the letters of reference marked thereon:—
Various trials resulted in the application of moveable collars a, and in
projection a', either in iron or steel. The defects in the temper of cast rundles.
or collars, and the fact that only a few designs could upon one pair of laminators
necessitate the use of a great number. of cylinders. By this Invention the
necessity of using more than one pair of cylinders in laminating metals in relief
or bas is avoided,.. The type cylinder (marked B in the Drawing) is that on
which I place the collars and rundles (rondelles); it is turned to a given
diameter. A groove b is then made therein to allow of a little square or sort of
key b; during the operation of turning, a ridge c is reserved so as to divide the
table of the cylinder into two unequal parts near the extremities of each of
the (now) two tables of the cylinder. Several square holes d are made, bored,
destined to receive in each a small puppet screw e in projection e¹. When I
fabricate flat iron, brass, or steel, imprinted on one side only, I take two type
cylinders B; on the first I introduce a sufficient number of rundles a, (rondelles)
plain (or without designs graved thereupon), either made of tempered iron or
steel. This, cylinder is now transformed into what is termed a collared lami-
nator c, c, or laminator with collar, on which may now be seen five rundles on
the right, and one on the left of the false ridge c; four of those on the right
(in the Drawing) are joined the one against the other, and the two more to the
left are not so joined, so as to make it evident that, they are distinct the one
from the other; but in practice, or when the cylinders are at work, the whole are
firmly joined together, so as to form only two tables or surfaces, the one to the
left, the other to the right of the ridge aforesaid c. These rundles are, however,
couped or adjusted, and they are afterwards maintained in their positions by the
puppet screws e, e¹, fixed into the holes d; the square or key b hinders them
from turning otherwise than in conjunction with the cylinder, and serve also to
encounter the designs by the means of a losing point, and in passing by the.
cuts (a) of these rundles or collars in such manner that the whole of the afore-.
said garniture and, the cylinder forms, as it were, one mass. On a second
cylinder Bare introduced or arranged in a similar manner the circles or rundles,
on which are the designs desired to be transferred on to the plain circles or

page_text: rundles fixed, and then one has also the laminator c', and thence, consequently,
a pair of laminators c, c', to laminate iron, brass, steel, &c., printing them on
one side only. On the cylinder c I have placed a circle, ring, or rundle u, with
the name of the Inventor, to shew that names can be laminated on the nictals
aforesaid. To laminate iron, brass, or steel called "rounds or squares," trans-
form the two cylinders B into two cylinders E, E', of the Drawing. I would
observe, that if it be desired to impress all the four faces, the articles must bé
placed twice. The cylinders D, D', serve also to print on both sides' designs on
flat surfaces. To fabricate ornamental rods neither' flat, round, or square, but
half round, oval, or grooved, or sunken faces, the little table of each rundle
should be graved thereon. The collection of collars and rundles, as lettered b
to z, in the Drawing, are all couped interiorly, and have a hollow cut therein;
their table surfaces are more or less large. l, m, n, r, u, x, represent two
borders and accompanyments of designs. o, p, g, s, v, y, serve to vary or enlarge
these or other designs. As, for example, the collar may be placed to the right
or left of the collar y, and forms a single design. The three collars x, y, , are
seen in the laminator c², united and forming a single design, as aforesaid. I,
therefore, with few rings or collars effect considerable work, using their com-
binations to form many designs; a design stamped on a rod, which shall please
the eye in itself, but be found too narrow alone, may be enlarged by placing on
its right or left other collars, as m, n, or several plain collars, as u, and then
the width required will be obtained. For fine ornamental work I use centres
and angles, as g; the collars f,f", giving the middle or centres, and g the
angles of framing desired to be constructed with this stripe, and so with the
others. When the required design is difficult of execution by the engraver on
the collar because of the channelling or fluting, the channel should be divided
into two or three rings; as, for example, the channelled ring p may be
replaced by the two half channelled rings q; q'. The tempering or repair of
the collars or ring is rendered easier and less expensive by this Invention, as
seperate collars may be repaired or tempered with greater facility than an entire
cylinder can be operated upon. On the laminators D, D', are seen united
rings or circles, as u, 'u¹, of 'different diameters, forming male and female
laminators. In the fabrication of sheet iron, brass, or steel with ornamental
designs in relief or bas relief, I procced in a similar manner, as herein-before
described. At F, F are two cylinders for sheet metal, differing from the
cylinder C, B, only inasmuch as the ridge C, serving as support to the circles or
rings u, g, h, and others, is at the extremity of each cylinder, and thus the
cylinder shows only one table surface or outer periphery. These circles or
rings are kept in their places by the puppets e, e¹, and d¹, d", as aforesaid. In

F is a design g, g, and for F¹ another design, because on thin sheets a different
design may be printed on each side at once.
In witness whereof, I, the said John Gedge, have hereunto affixed my
hand and seal, this Seventeenth day of July, in the year of our Lord
One thousand eight hundred and fifty-five.
