COMPLETE SPECIFICATION.
A New or Improved Matrix for Use in Type-casting.
I, Frederich Gustav Mour, of 1401, N. 29th Street, Philadelphia, Pennsyl-
vania, United States of America, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My invention consists of a type-casting matrix formed of metal superior to
that of the plate or bar in which the same exists, whereby many advantages are
attained as will be hereinafter set forth.
Referring to the accompanying drawing:
Figure represents a face view of a matrix and its holder embodying my
invention.
Figure 2 represents a section thereof on line - Figure 1.
Figure 3 represents a face view of the matrix removed from the holder.
Similar letters of reference indicate corresponding parts in the several figures.
A designates the matrix and B the bar or plate which holds the same.
In forming the matrix, the holder B is provided with a proper opening into
which the pattern die is inserted. Nickel of the thickness required for the work
is now electrically deposited around the die in said opening, the same filling said
opening and joining the walls of the holder, thus uniting the deposited metal with
said holder, and the die is removed, leaving the matrix of nickel.
The walls of the opening in the holder are formed with inclined or shouldered
sides so that the matrix is dovetailed or interlocked therewith as at C, and the
back of the opening is not entirely occupied with the superior metal, so that a
recess is left thereat, the same being filled as at D with a metal cheaper than
nickel but more serviceable than brass, such as copper, thus effecting a saving
of the superior metal while strengthening the back of the matrix.
It will be seen that the matrix will stand the greatest heat and pressure to
which it may be subjected, and endure the hardest metal that may be employed
in type-casting. It will preserve its original design without liability to burn-out,
thus avoiding frequent renewal, and as it is interlocked with the holder, it can-
not be drawn out nor loosen in casting the type. Its face cannot be scratched by
fitter's pointers and so the face of the type will not be marred and it will make
the type sharp and distinct, so that the printing will be better and furthermore
the type-height will be accurately maintained.
The holder is connected with a backing plate such as E by riveting or other-
wise, thus increasing the strength and durability of the holder proper and pro-
viding an additional support for the matrix at the rear thereof.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
Ist. A type-casting matrix formed of nickel electrically-deposited in the holder
therefor.

page_text: 2nd. A type-casting matrix formed of a metal superior to that of the holder
therefor and electrically-deposited in the latter.
3rd. A type-casting matrix formed of nickel electrically-deposited in the
holder therefor and interlocked with the wall of the latter.
4th. A type-casting matrix formed of nickel electrically-deposited in an open-
ing therein and interlocked with the wall thereof, and a filling in the back of the
matrix.
5th. A type-casting matrix formed of metal superior to that of the holder
therefor electrically deposited therein and interlocked with the wall thereof, and
a backing secured to the holder behind said matrix.
