Adjustable Drying-frame for Stereotypes Produced by the Cold
Process.
A communication to me from abroad by HERMANN WEHMANN, of Bremen, in the
Empire of Germany.
I, EDMUND EDWARDS, of the firm of Edwards and Co., of 35, Southampton
Buildings, Chancery Lane, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows
In stereotyping the process known as the cold process has the advantage over
the warm process that the stereotype moulds or dies dry quicker, the originals not
requiring to be previously heated. Hence the former is the only process applicable
to wood cuts which would otherwise under the action of heat be liable to split or
crack and become useless.
In the cold process the drying of the moulds or dies is carried out in iron frames
between which the edge of such moulds or dies is firmly clamped. These frames
have hitherto been made rigid, that is to say unadjustable, so that only mould
plates of corresponding size could be fitted therein.
It was therefore necessary either to provide a large number of frames, or to
make use, when only a large frame was at hand, of suitable plates corresponding to
the size of such frame and enabling a small mould plate to be clamped or fitted in
the latter.
The present invention has for its object to provide an adjustable drying frame in
which mould plates of any size i.e. from that of a newspaper to that of the smallest
letter may be clamped or fitted, whereby the work is greatly facilitated and a great
economy of material is effected.
The frame consists of upper and lower parts between which the mould is held.
The sides of each part are provided with longitudinal slots in which slide projecting
ribs upon the adjoining sides which fit in the slots. These ribs terminate with
screws passing through the slots and upon the outer ends of which are screwed nuts
which serve to lock together the various parts of the frame when the sides have
been adjusted in the slots to the size required. Two of the opposite sides of the
lower frame are provided with pins projecting from their upper surface, and
entering into corresponding notches in the upper frame, and upon the upper ends of
the pins are arranged lateral projections under which wedges can be driven, which
hold down the upper part of the frame, so that the mould is firmly held between the
two parts.
In a modified form, the parts of the frame may consist of smooth rectangular
bars, one end of each of which is furnished with a notch through which passes and
fits the corresponding end of the adjoining side bar which is fixed in the required
position by a set screw.
In order to alter the size in either direction of the improved frame, the opposite
nuts or screws are first loosened and the corresponding bars moved in the grooves
in the required direction and the nuts or screws are then again tightened.

Adjustable Drying-frame for Stereotypes Produced by the Cold
Process.
A communication to me from abroad by HERMANN WEHMANN, of Bremen, in the
Empire of Germany.
I, EDMUND EDWARDS, of the firm of Edwards and Co., l'atent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, 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 and accompanying drawing, that is to say:-
In stereotyping, the process known as the cold process has the advantage over
the warm process that the stereotype moulds or dies dry quicker, the originals not
requiring to be previously heated.
Hence the former is the only process applicable to wood-cuts, which would
otherwise under the action of heat be liable to split or crack, and become useless.
In the cold process, the drying of the moulds or dies is effected in iron frames
between which the edges of such moulds or dies are firmly clamped. These frames
have hitherto been made rigid or solid, that is to say unadjustable, so that only
mould plates of corresponding size could be fitted therein.
It was therefore
necessary either to provide a large number of frames, or to make use, when only a
large frame was at hand, of suitable plates corresponding to the size of such frame,
the use of these additional plates enabling a small mould plate to be clamped or
fitted in the frame.
The present invention has for its object to provide an adjustable drying frame, in
which mould plates of any size, from that of a newspaper for instance, to that of
the smallest letter, may be clamped or fitted, whereby the work is very much
facilitated and great economy of material is effected.
Two modifications of these frames are illustrated in the accompanying drawing,
in Figures 1 and 2 respectively. The sides A A¹ and B3 B¹ of each part of the
frame are provided with longitudinal slots, in which slide corresponding projecting
ribs upon the adjoining sides which fit in the slots.
These ribs terminate with screws passing through the slots, and upon the outer
ends of which are screwed muts F, which serve to lock together the various parts
of the frame when the sides have been adjusted in the slots to the size required.
Two of the opposite sides of the lower frame are provided with pins projecting
from their upper surface and entering into corresponding notches in the upper
frame, and upon the upper ends of the pins are arranged lateral projections a,
which can be turned round upon inclined projections or wedges so that the
upper frame is held down and the mould is firmly clamped between the two parts of
the frame.
In a modified form, shewn in Figure 2, the parts of the frame consist of smooth
rectangular bars, one end of each of which is furnished with a notch through which
passes and fits the corresponding end of the adjoining side bar, which may be fixed
in the required position by a screw.
The pins with the lateral projections and wedges are similar to those described
in the first form of arrangement.
In order to alter the size of the improved frame in either direction the opposite
nuts or screws are first loosened, and the corresponding bars are then moved in the
direction required until the frames are of the required size, the screws or nuts being
then again tightened.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
In drying frames for stereotype moulds, the separate frames A A and B B

manner described and shewn in the drawing.
