Improvements in Linotypes and Linotype Machines.
THOMAS PURVIS RITZEMA, Newspaper Proprietor, Quarry Glen, Blackburn, do
hereby declare the nature of this invention to be as follows:-
The nicking, bevelling, or tapering of slugs at the ends when being cast in
the moulds of linotype machines. A moving slide is inserted in the mould,
which opens when the slug is being ejected & closes automatically when the
mould wheel comes into position for casting.

Improvements in Linotypes and Linotype Machines.
I, THOMAS PURVIS RITZEMA, of Quarry Glen, Blackburn, in the County of
Lancaster, Newspaper Proprietor, 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:―
This invention relates to improvements in linotypes and linotype machines,
and consists of improvements in the manufacture of the slugs or types which are
cast with a bevelled or tapered recess or nick in their ends so that they can be
held in the fudge boxes with greater facility and with less likelihood of being
displaced. Nicks or recesses are formed in one or both ends of each slug or
type during the process of casting by employing in one or both ends of the
moulds a trigger-like slide mounted on a pin or stud, such slide being auto-
matically moved outwards from the mould when the slug or type is ejected in
the ordinary manner and closed or turned into the mould by the mould wheel
when the latter comes into position for the casting.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the annexed drawings, in
which:
Fig. 1 is a view in elevation of the interior of the mould for casting the slugs.
Fig. 2 is a similar view to Fig. 1, but the trigger-like slide is shewn out of the

page_text: mould and the slug or type is indicated by the dotted lines, being ejected
therefrom.
Fig. 3 is a plan view of the mould.
In all the views the mould is shewn constructed for casting slugs or types with
a recess or nick at one end only. If it is desired to have a nick or recess at each
end, there must be one of the trigger-like slides at each end of the mould.
According to this invention, in one half or side of the mould box 1 there is
formed a slight recess 2 in which is received the trigger-like slide 3, free to
move on the pin 4. The slide 3 has a nose or projection 5 corresponding to the
shape of the recess or nick to be formed in the slug or type. When the slug or
type is to be cast, the mould is closed, and the slide 3 is in the position shewn by
Figs. 1 and 3. The molten metal is run into the mould in the usual manner,
and the nose or projection 5 forms the nick or recess in the slug or type. The
slug or type when cast is ejected from the mould in the usual manner, the
trigger-like slide 3 being at the same time moved outwards to the position shewn
by Fig. 2. As the mould wheel moves to the position for casting, it comes into
contact with the projecting portion of the slide and presses same into the
mould (see Fig. 1) ready for the next slug or type to be cast.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I. declare that what I
claim is:-
(1) The mould box having the recess 2, and the pivoted trigger-like slide 3,
with nose or projection 5, in combination as and for the purpose herein described
and substantially as illustrated by the accompanying drawings.
(2) For casting slugs or type in linotype machines, the use in combination with
the ordinary mould box, of a trigger-like slide 3 pivoted & turning as herein
described and illustrated in the accompanying drawings.
Dated this 3rd day of November 1898.
