Year: 1858

page_text: LETTERS PATENT to George Schaub, of Birmingham,, in the County of
Warwick, Electro-Metallurgist, for the Invention of "A NEW OR IM-
PROVED MANUFACTURE OF CERTAIN KINDS OF PRINTING TYPE AND OTHER
PRINTING SURFACES."
Sealed the 27th July 1858, and dated the 22nd February 1858.
PROVISIONAL SPECIFICATION left by the said George Schaub at the
Office of the Commissioners of Patents, with his Petition, on the 22nd
February 1858.
I, GEORGE SCHAUB, of Birmingham, in the County of Warwick, Electro-
Metallurgist, do hereby declare the nature of the said Invention for "A NEW
OR IMPROVED MANUFACTURE OF CERTAIN KINDS OF PRINTING TYPE AND OTHER
PRINTING SURFACES," to be as follows:-
My said Invention consists of manufacturing, in the manner herein-after
explained, the large printing types which are usually made of wood or of type
metal mounted upon wood, and also manufacturing by the same method blocks,
stereotypes, and such other printing surfaces as the said method is or may be
applicable to.
In carrying my Invention into effect, I prefer to make the head or printing
surface of the type of copper by the well-known process of electro-deposition.
I attach the type head to a body of cast iron, which said cast-iron body is
hollow on its under side; the type head is attached to the cast-iron body by
screws, pins, or otherwise; and I place between the type head and body gutta
percha or other cement, or composition, or soft metal, which fills up the type
head, and causes it to embed itself firmly on the body. The type head may:
be strengthened by tin or solder fused to its back. I give the type the
required height by placing it or a number together, face downwards, upon a-

page_text: plane surface, and by a planing machine cutting away the edges of the type
body until the type has been reduced to the required height.
Although, for convenience of description, I have only referred to a type, yet
the process described is the same whether I apply my Invention to the
manufacture of types, or ornamental blocks, or stereotypes, or other printing
surfaces, printed from after the manner of types. Although I prefer to make
the type head or printing surface by electro-deposition, as described, yet the
said type head or printing surface may be made from sheet metal by the well:
known process of raising in dies,
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Schaub in the Great Seal Patent Office on the
16th August 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
SCHAUB, of Birmingham, in the County of Warwick, Electro-Metallurgist,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of February, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant. unto
me, the said George Schaub, Her special licence, that I, the said George
Schaub, my executors, administrators, and assigns, or such others as I, the.
said George Schaub, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 "A NEW OR
IMPROVED MANUFACTURE OF CERTAIN KINDS OF PRINTING TYPE AND OTHER PRINTING.
SURFACES," upon the condition (amongst others) that I, the said George
Schaub, 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 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 George Schaub do hereby declare the
nature of the said Invention, and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:
My said Invention consists of manufacturing in the manner herein-after.
particularly described and illustrated in the accompanying Drawing, the large:
printing types which are usually made of wood or of the alloy called type.
metal, or of type metal mounted upon wood; and also manufacturing by the:
same method blocks, stereotypes, and such other printing surfaces as the same:
is or may be applicable to.
'
I will describe and illustrate my Invention in its application to a printing
type, from which description and illustration I believe the application of my:
Invention to blocks, stereotypes, and other printing surfaces printed from
after the manner of types will be sufficiently understood and readily carried
into effect.
In manufacturing printing types according to my Invention I prefer to
make the head or printing surface of the type of copper by the well-known
process of electro-deposition, I attach the type head to a body which I make>
by preference of cast-iron, which said cast-iron body is hollow on its under side.:
Although I prefer to make the hollow body of cast iron, yet any other suffi-
ciently hard and inexpensive material may be employed in place of cast-iron.:
The type head is attached to the cast-iron body by screws, pins, or otherwise,:
and I place between the type head and cast-iron body gutta percha, or other
cement, or composition, or soft metal, which fills up the type head, and causesi
it to embed itself firmly on the cast-iron body. The type head may be
strengthened by tin or solder fused to its back.

Figure 1 of the accompanying Drawing represents in plan a printing type
constructed according to my Invention; Figure 2 represents the same.
in longitudinal vertical section; Figure 3 represents an edge view of the:
same; and Figure 4 represents a transverse vertical section of the type taken
through the line a, Figure 1. The same letters indicate the same parts in the
several Figures; 6 is the type head attached to the cast-iron body c by the
pins d, d, the said pins being passed through holes in the said type head b and
cast-iron body c, and the said pins d, d, rivetted to the said cast-iron body cas
seen in the section Figure 4.
The cast-iron body c is represented in plan, longitudinal section, and trans-
verse section in Figures 5, 6, and 7, respectively.
The composition on which the type head b is embedded is marked e,
in Figures 2 and 4. In embedding the type head 6 on the cast-iron body c,
I prefer to employ the cement or composition known in commerce as Keene's
cement; the said cement sets hard and is well adapted to resist the pressure to

page_text: which the type is subjected in the printing press. As the composition of the
said Keene's cement is well known, and the said cement commonly employed.
for various purposes, I do not think it necessary here to describe its compo-
sition. I give the type, Figures 1, 2, 3, and 4, the required height by placing
it, or a number of the said types together, face downwards, upon a plane
surface, and by a planing machine I cut away the edges of the type body c
until the type or types have been reduced to the required height. As the
process of electro-deposition by which the head of the type is produced is well
known and commonly practised, and constitutes no part of my Invention, I do
not think it necessary to describe the same.
Although in carrying my Invention into effect I prefer to make the type
head or printing surface by electro-deposition as described, yet the said type
head or printing surface may be made from sheet metal by the well-known
process of raising in. dies.
Having now. described the nature of my said Invention, and the manner
of carrying the same into effect, I wish it to be understood that I do not limit
myself to the precise details herein described and represented, as the same may
be varied without departing from the nature, of my Invention; but I claim as
my Invention the new or improved manufacture of printing types and other
printing surfaces herein-before described and illustrated in the accompanying
Drawing, that is to say, manufacturing the large printing types which are
usually made of wood, or of type metal mounted upon wood, or of type metal.
wholly, also blocks, stereotypes and other printing surfaces printed. from,
after the manner of types, by first forming the head of the type or other
printing surface by electro-deposition or by mechanical means, and afterwards
fixing the said type head or printing surface upon a body of cast-iron or other
sufficiently hard and inexpensive material, the said type head or printing.
surface being made to embed itself on the body, and to assume its proper level
or nearly its proper level thereon by means of a cement interposed between the
type head or printing surface and the said body..
In witness whereof; I, the said George Schaub, have hereunto set my
hand and seal, this Fourteenth day of August; in the year of our
Lord One thousand eight hundred and fifty-eight.
Witness,
GEORGE SCHAUB. (L.S.)
