We THOMAS WHITE SMITH of the firm of Caslon & Co of the Caslon Letter
Foundry Chiswell Street in the County of Middlesex Letter Founder and RICHARD
JOSEPH CHITSON of 294 Old Ford Road in the same County and in the employ
of the said firm Foreman do hereby declare the nature of our invention for
IMPROVEMENTS IN APPARATUS EMPLOYED IN THE CASTING OF METAL TYPE to be
as follows:-
The object of our present invention is to further develop and increase the utility
and application of the invention for which Letters Patent were granted to me,
the said Thomas White Smith dated the 24th day of April 1879 N° 1611 for
'Improvements in apparatus employed in the casting of metal type and to
render the same applicable to the manufacture of apparatus for the casting of
Phrasotypes, Logotypes, or type combinations of several letters marks or signs and
to facilitate and cheapen the cost of manufacture of such types.
The formation or casting of logotypes has hitherto been attended with great
cost for punches and matrices especially when such cost and trouble is taken into
comparison with the comparatively limited demand for each particular description
of such type.
In carrying out our invention we form each letter, mark or sign which goes to
form the logotype or phrasotype in the manner described in the specification
aforementioned and then having obtained a set or collection of such copper
matrices reduced as therein set forth and placed side by side with a steel or other
sufficiently hard metal preferably steel piece on each outer side of the series or
each series we secure them in situ for the time being in a proper adjustable clamp
or holder.
Thus the mould or matrix of the phrasotype or logotype is composed of a set'
or collection of matrix moulds or type reverses for casting as readily as types
themselves are composed for printing and the steel, sides obviate the necessity for
"rubbing" with resultant economy of time, superiority of logotype or phrasotype
manufacture and avoidance of the enormous outlay that it would be requisite to
incur in order to place a type founder in a position to be able to supply on demand
logotypes not in stock and of all the possible combinations.

Improvements in Apparatus Employed in the Casting of
Metal Type.
I THOMAS WHITE SMITH of the firm of Caslon & Co of the Caslon Letter
Foundry Chiswell Street in the County of Middlesex Letter Founder and RICHARD
JOSEPH CHITSON of 294 Old Ford Road in the same County and in the employ
of the said firm Foreman do hereby declare the nature of our invention for
IMPROVEMENTS IN APPARATUS EMPLOYED IN THE CASTING OF METAL TYPE, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
"
The object of our present invention is to further develop and increase the utility
and application of the invention for which Letters Patent were granted to me the
said Thomas White Smith dated the 24th day of April 1879 N° 1611 for
Improvements in apparatus employed in the casting of metal type" and to
render the same applicable to the manufacture of apparatus for the casting of
Phrasotypes, Logotypes, or type combinations of several letters marks or signs and
to facilitate and cheapen the cost of manufacture of such types.
The formation or casting of logotypes has hitherto been attended with great
cost in the production of electrotype matrices for each separate word especially
when such cost and trouble is taken into comparison with the comparatively
limited demand for each particular description of such type.
In carrying out our invention we form each letter, mark or sign which goes to
form the logotype or phrasotype in the manner described in the specification of my
said Letters Patent aforementioned and then having obtained a set or collection of
such copper matrices reduced by the removal of the sides of such matrices as
therein set forth and placed side by side with a steel or other sufficiently hard
metal preferably steel piece on each outer side of the series or each series we secure
them in situ for the time being in a proper adjustable clamp or holder.

Figure 1 shews a face view and Figure 2 a section of a set or collection of such
copper matrices a (say) adapted to produce a Logotype Caslon Foundry
produced by the exercise of the invention set forth in the specification 1611
of 1879 and these separate matrices selected, each consisting in the example given
of a separate letter or sign i,e, C, a, s, 1, o, n, F, o, u, n, d, r, y, and with a space or
filling piece c¹ between the n, and the F, are placed side by side with a steel or
other sufficiently hard metal, preferably steel, piece c on each outer side of the.
series and this series with the steel pieces c and an end piece d are secured in a
clamp e¹ with under side or floor e and therein secured by screws e², e³.
Figure 3 shews a back view, and Figure 4 au end view of the same. Figure 5
shews the clamp e¹ with the matrices a removed. Figures 6 and 7 shew face and
side view separately of a matrix a adapted to produce the portion "C" of the
logotype instanced.

Figures 8 and 9 shew like views of one of the steel pieces c. Figures 10 and 11
shew like views of an end piece.

or collection of matrices, moulds, or type reverses, for casting (interchangeable
and capable of arrangement into words or otherwise at will) as readily as types
themselves are composed for printing and the steel sides obviate the necessity for
rubbing" with resultant economy of time, superiority of logotype or phrasotype
manufacture and avoidance of the enormous outlay that it would be requisite to
incur in order to place a type founder in a position to be able to supply on demand
logotypes of all the possible combinations.
"
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that we
make no claim to any portion of the invention for casting type described in the
specification of Patent N° 1611 dated 24th April 1879 separately but what we do
claim is
The improvements in apparatus employed in the casting of metal logotypes,
phrasotypes or type combinations of letters, marks or signs in manner substantially
as set forth.
Dated this 15th day of July 1885.
