PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Casting Lines of Type.
I, ARTHUR HERBERT ALEXANDER, of 55 Radnor Street, in the City of
London, do hereby declare the nature of this invention to be as follows:-
Lines of type are cast in moulds whose length is the length of the line, their
width the height of the type and their height the thickness of the type, the metal
being injected from the back of the mould against plates forming the front and in
which the letters are sunk. Such woulds as at present made are not adjustable
in size a different mould having to be used for each length of line or thickness
of type.
The object of this invention is to construct an adjustable mould in which the
length of line and thickness of type can be varied at pleasure.
The top and bottom of the mould are made of metal plates bolted together and
one end is formed of a flange fixed to one of these plates and entering a slot in the
other so that a tight joint is made whatever may be the distance of the plates
apart. The other end of the mould is formed of one or other of a number of slides
of different thickness according to the thickness of type desired. The distance of
the plates apart is preferably regulated by polygonal surfaces eccentrically
pivotted to the lower plate, the upper plate resting on one or other of their sides.
The mould is set for any thickness of type by slacking off the bolts, turning the
polygons until their proper side is uppermost, introducing a slide of the proper
thickness and then tightening the bolts.
The slides are attached to a rack gearing with a pinion pivotted to one of the
plates. By turning this pinion the slide is traversed along between the plates and
the length of the line is varied.
Preferably the slide has attached to it two tail pieces parallel to each other
throughout most of their length but slightly approaching each other at the end
remote from the slide. The rack is received between these tail pieces which are
sprung on to it.

I, ARTHUR HERBERT ALEXANDER, of 55 Radnor Street, in the City of
London, 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 :-
Lines of type are cast in moulds whose length is the length of the line, their
width the height of the type and their height the thickness of the type, the metal
being injected from the back of the mould against plates forming the front and in
which the letters are sunk.,
The object of this invention is to construct an adjustable mould in which the
length of line and thickness of type can be varied at pleasure.
The top and bottom of the mould are made of metal plates bolted together and
one end is formed of a flange fixed to one of these plates and entering a slot in the
other so that a tight joint is made whatever may be the distance of the plates
apart. The other end of the mould is formed of one or other of a number of slides
of different thickness according to the thickness of type desired. The distance of
the plates apart is preferably regulated by polygonal surfaces eccentrically
pivotted to the lower plate, the upper plate resting on one or other of their sides.
The mould is set for any thickness of type by slacking off the bolts, turning the
polygons until their proper side is uppermost, introducing a slide of the proper
thickness and then tightening the bolts.
The slides are attached to a rack gearing with a pinion pivotted to one of the
plates. By turning this pinion the slide is traversed along between the plates and
the length of the line is varied.
Preferably, the slide has attached to it two tail pieces parallel to each other
throughout most of their length but slightly approaching each other at the end
remote from the slide. The rack is received between these tail pieces which are
sprung on to it.
Figure 1 is a side elevation of the mould, Figures 2 and 3 are end views,
Figure 4 is a plan, Figure 5 a plan of the bottom portion and Figure 6 an under-
side view of the top portion. Figure 7 is a side elevation, Figures 8 and 9 are
end elevations, Figure 10a plan, and Figure 11 an underside view (partly in
section) of the rack piece. Figure 12 is an underside view, and Figure 13 a side
elevation of one of the slides. Figure 14 is a side elevation of another slide of
different thickness. In Figure 10 one of the slides is shown in place on
the rack.
a is the space in which the metal is cast. It is bounded on the top by the
plate b. (in which the usual grooves bare formed), on the bottom by the plate c,
at the right hand end by the flange d and at the left hand end by the slide e. The
flange dis, made in one piece with a base d', a back d and a lug d³. This piece is
secured to the plate c by screws f (Figure 5). The flange d, back t² and lug d³
enter recesses 62 63 64 (Figure 6) respectively in the plate b. The slides e have
spring tail pieces which fit over lugs g' on the underside of the rack piece g; in
Figure 11 one of these lugs is partly in section to shew that it is undercut at the
corners to receive the hooks or points e² at the ends of the tail pieces e¹. Notches e³
are also formed in the slides e to fit on the projection 93 on the rack piece. The
lugs g¹ are higher than the thickness of the tails e¹ and project beyond them into a
slot or recess c¹ in the plate c. The upper side of the rack piece also has lugs g³ g³
which fit into slots 6³ ³ in the plate 6. The plate 6 has a lug 66 which fits in the fork
of the rack piece g.
The rack piece 9 carries a spring g³ which lifts it when the plate bis removed so
that it can be readily taken hold of.

page_text: h is a pinion pivotted in a recess in the side of the plate b. This pinion gears
with the teeth 9 of the rack piece g and is turned by a key so traversing the rack
piece g and slide e. The pinion is covered by a sliding plate or door ; secured by
a catch j; in Figure 1 this plate has been removed to show it. The plates b and c
are secured together by bolts k and are kept at the proper distance apart by the
three polygons pivotted in recesses in the plate c and whose axes can be turned
by a key. The front right hand polygon is covered by a sliding plate m working
in dovetailed recesses 6' and c² in the plates b and c. The plate m is secured by a
catch m' and in Figure 1 it is removed to show the polygon 1.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In moulds for casting lines of type the combination of two ends, a top plate,
a bottom plate and polygons pivotted with their sides at different distances from
the pivots to one plate and forming distance pieces against which the other
plate rests.
2. In moulds for casting lines of type the combination of a fixed end, a moveable
end, a top plate, a bottom plate, a rack up the moveable end and a pinion pivotted
to one of the plates.
3. In moulds for casting lines of type the combination of a top plate, a bottom
plate, means for adjusting their distance from each other, an end fixed to one of
the plates and entering a slot in the other, a moveable end and means for adjusting
its distance from the fixed end.
4. In moulds for casting lines of type, the combination of a top plate, a bottom
plate, means for adjusting their distance from each other, an end fixed to one of
the plates and entering a slot in the other, a pinion pivotted to one of the plates,
a moveable piece carrying a rack gearing with the pinion, and end pieces of varying..
thickness attachable to the rack piece.
5. In moulds for casting lines of type the combination of a top plate, a bottom
plate, polygons pivotted with their sides at different distances from the pivots to
one plate and forming distance pieces against which the other plate rests, an end
fixed to one of the plates and entering a slot in the other, a pinion pivotted to one
of the plates, a moveable piece carrying a rack gearing with the pinion, and end
pieces of varying thickness attachable to the rack piece.
