Improvements in the Moulds of Linotype Machines.
We, WILLIAM HENRY LOCK, Manager and Secretary of the Linotype Company,
Limited, of No. 188, Fleet Street, in the City of London, and CHARLES HOLLIWELL and
WARWICK JAMES LEWIS, both of the Linotype Works, Broadheath, in the County of
Chester, Engineers, do hereby declare the nature of this Invention to be as
follows:-
The present invention consists in improvements upon the moulds described in the
Specification of Letters Patent 6170 of 1896. According to the invention described
therein, the coring of a linotype mould is effected by passing core pieces down into
the mould cavity through the cap plate just before the act of casting, and withdrawing
them soon enough to allow of the linotype being ejected. There was one imperfection
in that invention and that was this: the cap plate might be deprived of its minimum
necessary rigidity, by the width of the core pieces. Narrow core pieces left the cap
plate rigid enough, but as they became wider, they left it too weak to do its work
properly. In any case, there was a hole through the cap plate of the same size as
the core.
The present invention includes means for obviating the presence in and passing
through the cap plate, of the core pieces; and, consequently, it includes means for
coring the mould cavity to any extent in the direction of any one or more of its three
dimensions.
The present invention does not cut any holes in the cap plate. The integrity of
the latter is provided for by fastening the cores to its casting face or to that of the
bottom plate. The end liners too may be carried by either plate. There are combined
with the cap plate, automatic devices by which it is held away from the bottom plate
for a distance not less than the thickness of the linotype. Such a device may consist
advantageously of guide pins fast to one plate and working in holes in the other
one, and spiral springs around the pins and bearing upon both plates. The cap plate
is moved towards the bottom plate till the end liners are in contact with them both
and locked in that position just before the act of casting. This may be effected by
any suitable automatic device. One of the star wheel type is preferred, because it
lends itself so readily to the work of unlocking the cap plate just before the newly cast
linotype is to be ejected. When a star wheel is used, it is pivotted upon the face of
the mould wheel near enough to the cap plate for one of its teeth, when turned in the
right direction, which is one of right angles with the length of the mould, to hold
the Cap in the desired position. There is advantageously interposed between the
top of the cap plate and the respective tooth, a spring bar. This is made fast by
its ends to the top of that plate from which it stands away norinally at a short
distance, so that when the tooth has pushed the cap plate up to the bottom plate;
the spring bar being then in compression, exerts a spring pressure upon the said
plate.
The means by which the star wheel, or its substitute, is actuated, consists of two
fingers fixed at suitable distances apart upon some convenient part of the machine.

page_text: One finger engages a second tooth of the star wheel and turns the latter far enough
to make the tooth above mentioned, push the cap plate up and lock it in that position.
As the wheel moves up into the ejecting position, the second fixed finger engages a
third tooth of the star wheel and unlocks the cap plate, whereupon it is automatically
moved away from the bottom plate.
A substitute device for moving the cap plate away from the bottom plate, consists
of rods projecting from the former through or past the latter and presenting their
outer ends in a proper position for being engaged by the justifying apparatus at the
proper monent.
At the moment the cap plate is moved away from the bottom plate, there obviously
arises the necessity of supporting the newly cast linotype. This may be met by
the liners being fast to the casting face of the bottom plate, for then their ends would
align with the ends of the cores, but a better means consists of a device of the
nature of a finger or piece of any suitable formn fast to the bottom plate and projecting
into the mould cavity. It is proposed that such a piece should have the form of a
double V ridge standing parallel with the direction of ejection and extending for about
three quarters of the width of the mould cavity. The ejector blade is slotted to clear
such a piece.
In casting narrow linotypes such as one required for late news on machines whose
cylinders may not be cut away to make room for linotypes of full width, in a mould
cavity cored as above described, they are in fact cast the full width, but the core is
so shaped that the area of the linotype beyond the narrow width, is gradually
diminished from the standard thickness along the foot, to the smallest thickness
that will stand the push of the ejector during the act of trimming the sides of
the linotype. After the latter has reached the galley, it will be easy to snap off
the git.
The separation of git and linotype may be effected automatically as follows. The
git is held to the cap plate by means similar to those which hold the linotype
to the bottom plate. The ejector blade carries suitable projections which engage
the git and eject it without pushing it into the space between the knives.

Improvements in the Moulds of Linotype Machines.
We, WILLIAM HENRY LOCK, Manager and Secretary of the Linotype Company,
Limited, of 188, Fleet Street, in the City of London, and CHARLES HOLLIWELL and
WARWICK JAMES LEWIS, both of the Linotype Works, Broadheath, in the County of
Chester, Engineers, 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 :-
The first part of the present invention consists in improvements upon the
mechanism described in the Specification of Letters Patent 6170, March 19th 1896,
for coring the moulds of the linotype machines described in the Specification of
Letters Patent 14582 September 16th 1890. In that machine, the mould is built
up of four pieces, a cap plate, a bottom plate, and two distance pieces, the whole
held together by screws to form a mould block having a horizontal slot or mould
cavity for the body of the linotype, the cavity extending through
the block from the front to the rear of it. The said block is
carried by a gear wheel commonly known as the mould wheel and to which it is

page_text: fixed with its cavity standing parallel with a diameter of it, and in a hole in it so
that the said block extends through the wheel. The wheel is turned about its axis
through a certain are and moved forward to hold the mould cavity in the casting
position between the composed line of matrices and space bars in front of it and the
metal pot mouth piece behind it, whereupon the linotype is cast. The metal pot and
mould wheel are then moved back and the mould wheel is turned again to hold the
said mould block cavity with the linotype in it, between the ejector and the galley
and moved forward again, whereupon the blade of the ejector is advanced through
the said cavity and pushes the said linotype out into the galley.
According to the invention described in the first mentioned Patent, the coring of
the mould cavity is effected by passing a core or cores down into it through the cap
plate just before the linotype is cast and withdrawing them soon enough to clear the
advancing ejector blade. There is however, one imperfection in that invention, and
it is that the width of the core or corés (transversely of the mould cavity, that is)
may be and sometimes is sufficient to weaken the cap plate, thereby depriving it of
the degree of rigidity necessary to it as an operative member of the mould block.
So long as the cores are narrow, the necessary rigidity of the cap plate is not inter-
fered with, but as their width increases the cap plate is weakened, for in any case,
there must be holes through it large enough for the cores to work through.
The present invention like the one just mentioned, has been conceived and
developed with special reference to the machine described in the second Patent above
mentioned; and for that reason, its application to that machine has been selected
for illustration and detailed description. It does not require any core holes in or
through the cap plate, but provides for the integrity of it being maintained, by
fastening the cores as well as the distance pieces to the casting face-i.e., the face
that forms the respective side of the mould cavity-of the cap plates. The cores
being then a fixture within the mould cavity, it becomes necessary to open the mould
by moving the cap plate away from the bottom one for a distance not less than the
thickness of a linotype, in order that there may be room for the cores and the
linotype to stand clear of each other when the ejector blade advances. Preferably,
only the cap plate is movable, not the botton plate as well or as an alternative, but
only because for reasons outside this invention it is desirable that the bottom plate
be a fixture upon the mould wheel.
The newly cast linotype is held to the bottom plate when the mould is open, by
means of a double V-ridge standing across the face of that plate, the ejector blade
being slotted to clear it. The mould must be closed by moving the cap plate
towards the bottom plate till the distance pieces are in metal tight contact with the
casting face of the latter, and locked in that position before the mould wheel reaches
the casting position. The type of closing and locking device is varied according as
to whether it is outside the mould block or whether it is between the latter and the
axis of the mould wheel.
The invention includes improved means for casting narrow linotypes such as are
required for late news on printing machines whose cylinders may not be cut away to
make room for linotypes of full width. These linotypes are generally cored out,
either in their ends or in their feet. In either case the cores are made fast to the cap
plate as already described. While the narrow linotype is held to the bottom plate,
the sprue is held to the cap plate by similar means, so that it is broken off the
linotype when the mould is opened. The ejector blade is provided with a lateral
projection adapted to eject the said sprue from the mould cavity without pushing
it beyond, so that it drops therefrom instead of being pushed forwards into the
trimming mechanism.
Referring to the accompanying figures which are to be taken as part of this
Specification and read therewith,

O, is the mould wheel; o³, the gear with which its driving pinion (not shewn)
engages; o, the cap plate; o¹s, the bottom plate; 013, 014, the two distance pieces,
the four last mentioned parts constituting the mould block; o, the horizontal slot
or mould cavity in it; o, the hole in the wheel O into which the rearwardly pro-
jecting portions of the mould block project and p, p, steadying sockets, all as
heretofore.
According to the first part of the present invention, the cores c³, c³, and the distance
pieces o¹³, o, are made fast to the casting face of the cap plate o17 as shewn in
Figures 1 and 4.
The provision illustrated in Figures 1 to 4 for the cap plate 017 being movable
away from the bottom plate 018, consists of a pin o fast to and projecting from each
end of the bottom plate ole in the direction of the cap plate 17, holes 0130 through the
latter to receive the said pins, and an expanding spiral spring 0131 seated in a circular
socket 0182 in the casting face of the bottom plate o18 about each pin 0129 and constantly
pushing against the distance pieces o¹³, 01. The pins o¹ are long enough to allow
of the cap plate o17 being moved away from the bottom plate o¹s for a distance not
less than the thickness of the linotype C as shewn in Figure 1. The cap plate o¹ is
prevented from being moved too far by the outer side of the hole 030, the rear portion
which stands in that hole being thinner than heretofore to allow of the above
described motion of the said cap plate. As the latter is moved away from the bottom
plate os, it leaves the linotype C unsupported. To prevent it falling over towards
the cap plate, there is an undercut or double V-ridge o extending transversely
across the casting face of the bottom plate 018 for about three quarters of the width
of the latter, more or less, and which holds the linotype C in its normal vertical
position close up to the plate o¹8 by reason of the linotype metal engaging behind
the said ridge as illustrated in Figure 1, the linotype C being drawn in section to
shew that engagement. The ejector blade 04 has a suitable longitudinal groove 05
in it to clear the said ridge o136, as illustrated in Figures 12 and 13. The ridge o136
may be replaced by under-cut grooves (70 described further on with reference to
Figures 5, 8, 9 and 10.
The preferred device for unlocking the mould and closing and locking it again,
consists of a star wheel 133 pivotted by a stud 0134 on the face of the mould wheel O
so as to turn in a plane parallel therewith as indicated in Figures 1, 2, 5 and 6. The
stud 0134 stands at equal distances from the two ends of the cap plate o" and the
length of the teeth of the star wheel 13 is such that if any one of them be set to
stand in the direction of the mould cavity o and at right angles with it, it will close
the mould by moving the cap plate o towards the bottom plate o¹s until the distance

page_text: pieces 13, 14, on the former, are in metal tight contact with the casting face of the
latter, and lock it there. There is advantageously interposed between the top of the cap
plate o and the star wheel 0133, a spring bar o185 made fast by its two ends to the
said top, from which it stands clear for a short distance as shewn in Figures 1 and 5,
so that when the said tooth has pushed the cap plate 17 up to the bottom
plate 18 in. the way described, the spring bar o135, being then in tension, exerts a
spring pressure upon the said cap plate c17 in the direction of the bottom plate o¹9
The device by which the star wheel 133 is moved to unlock the cap plate o17 and to
close the mould and to lock the said plate 017 again after the linotype C has been
ejected from the mould cavity o, consists of two fingers 0, 058, which are held to
the frame of the machine by any suitable means so that they shall both stand in
the plane of the teeth of the star wheel 0133 Both fingers are shewn as screwed
to a piece O which is fixed to the mould wheel slide of as shewn in Figures 6 and 7.
The finger 058 projects nearer to the axis of the mould wheel O than does the
finger O for a reason which is explained farther on. The arcual distance between
them and their position with reference to the mould block will be clearly understood
from the following description of the way in which the invention constructed as
described above, works. When the mould wheel O is in the casting position, the
mould block is in the position and condition illustrated by the dotted lines in
Figures 1, 5 and 7. At that time, one of the teeth of the star wheel 0133 - say the
tooth 060 is holding the cap plate o locked down with its distance pieces 013, 014,
in metal tight contact with the bottom plate 18. After the linotype C has been
cast, the wheel O is turned in the direction of the arrows in Figures 1 and 5,
through an are of 270°, so holding the mould cavity with the linotype in it
between the ejector blade 0+ and the trimming knives. The said wheel is then
ready to be moved forward into the ejecting position. Towards the end of the
are of 270°, the tooth 001, being the one opposite to the then locking tooth co
and projecting farther than any of the four from the axis of the mould wheel O,
finds the finger 07 projecting into its path, sufficiently far to turn it through
an are of 45° which suffices to make the star wheel 0133 assume the position
illustrated by the full lines, thereby unlocking the cap plate o17 and allowing the
springs 131 to open the mould, as shewn. So long as the cap plate 017 is
unlocked, the teeth 000, 002 are in equal touch with the spring bar o, thereby
holding the star wheel o133 steady. The mould wheel is then moved forward into
the ejecting position and the linotype C is ejected as heretofore. The ejector blade 0+
is then retracted, and the mould wheel O, after having been moved back, is moved
through an are of 90° in the same direction as before. The tooth 003, then finds
the finger 08 projecting into its path far enough to turn the star wheel 133 to
make the tooth 02 close the mould again in readiness for the next cast, as
illustrated by the dotted lines in Figures 1, 2, 5 and 7. Each of the four teeth of
the star wheel 13 takes the several duties in turn. The radial distance of the tip of
the tooth (6 from the axis of the wheel O before its contact with the finger 057, is
greater than that of the tooth (63 before its contact with the finger 058; hence the
latter must be correspondingly longer than the finger (57.
Referring to Figures 5, 6 and 7, there is illustrated therein a modification of the
device for opening the mould. According to it, the pins o120 are replaced by pins 01
which pass through holes in the bottom plate 18 and project beyond the latter for
a certain distance when the mould is closed, where they meet a bridge piece 0% to
which they are made fast. These pins 06+ are sufficiently long to hold the mould
open when the bridge piece 003 is close up to the bottom plate 018 as illustrated by
the full lines in Figure 5, but no longer than that. The holes in the said bottom
plate o¹s are only large enough to allow the pins 04 to work through freely. Oce is
a recess in, and 007, a decline on the face of the bridge piece O next to the axis of
the mould wheel O, the two joining each other and standing in the respective
positions illustrated in Figure 5. 073 is a collar fast on each pin 0. To control
the opening motion of the bridge piece 065, a stop is provided. It is shewn in
Figure 5 as being the cheese head of a screw turning in the mould wheel O, notched

page_text: .
.
to facilitate the turning of it and having a flat side 074, the radial distance of the
said side from the axis of the screw being less than that of the arcual side 075 for a
reason explained further on. The side 07 stands opposite the bridge piece 005 when
the mould is to be opened and closed. The function of the flat side 074 is described
further on. Os is a projection fast on the justification rod ps. The projection OGS
and the decline 007 replace the springs os. This projection works vertically in
suitable guides in front of the mould wheel O as indicated in Figure 5. It receives
its notion a reciprocating one-from a bell erank lever which has its fulcrum
on a transverse rod 7,8 as illustrated in Figure 14. It is the front end of the said
lever that connects with the rod 8 near its bottom end. The full details of these
two last mentioned parts and the means for working them are not included in the
present Specification because they do not concern the present invention. They are
to be found in the Specification of Patent 14582 of 1890. 15 is the cam that works
the lever p through the constant engagement of its periphery and an antifriction
roller on the rear end of the said lever as illustrated in Figure 14. The cam pl
turns in the direction indicated by the arrow. As soon as the mould wheel O has
been brought into the position illustrated by the full lines in Figure 5 and before it
is moved forward ready for the new linotype to be ejected from the mould, the
justification rod p8 is raised by the antifriction roller being pulled into drop 7" in
the periphery of the cam p15, which drop the motion of the said cam has brought up
opposite the said roller. The projection 063 on the rod p is then opposite the
recess as shewn by the dotted lines in Figure 5. The inould wheel O is then
moved forward into the ejecting position, thereby placing the decline 007 immediately
underneath the projection 08. The rise 76 then engages with the lever pl through
the antifriction roller and rocks the front end of the said lever pl down, thereby
pulling the projection down the decline 07 and opening the mould by moving the
cap plate away from the bottom plate ots.
The mould cavity for the linotype is, preferably, in the cap plate o, but it will be
frequently necessary to change the latter. To allow of this being done, the sockets 0182
are deep enough to allow of the collars Os being drawn into them far enough for the
pins 04 to be drawn out of the cap plate o ,-see Figures 8 and 9-the radial distance of
the flat side O being less than that of the arcual side 0% to allow of the bridge piece 005
being moved accordingly. When the stop is turned until its flat side 07 is opposite to
and parallel with the respective face of the bridge piece 05 the latter can be moved from
the bottom plate o¹s far enough to draw the pins 064 out of the holes 0130 in the cap
plate o, so leaving the latter free to be removed.
It should be noted with reference to the cores, that neither the number, the shape,
nor the position of them, nor even the width of the linotype, has anything to do with
the present invention-the only respect in which the latter affects them is their being
fast on the cap plate o17 instead of being passed through it. This is fully illustrated
in Figures 8 to 11 which shew a core c20 capable of forming a double V recess in the
foot of a linotype C26. The latter is a narrow one instead of one of normal width like
the one C illustrated in Figure 1. Here there is an instance of difference in number,
shape and position of the cores and also a difference in the width of the linotype, but
the means by which the core c is carried, are not changed-it is still fast to the cap
plate o
The second part of the present invention consists in means for casting narrow
linotypes, i.e., those of any width or height to paper, less than the normal, such as
are required for late news on machines whose cylinders may not be cut away to make
room for linotypes of normal width. In point of fact, this second part of the inven-
tion does cast them of full width, but there is a core for the excess width so shaped
that the area of the linotype beyond the desired width is gradually diminished from
the standard thickness along the foot of the linotype, to the smallest thickness along
the connection of the said excess width sprue or git, and the desired width or narrow
linotype, that will stand the push of the ejector during the act of trimming the sides
of the latter. This second part is illustrated in Figures 8 to 11. These figures
illustrate in addition to the said second part, the coring of the mould to form a

page_text: C21
double recess in the foot of the narrow linotype C220 is the core in question.
The linotype C is held to the bottom plate o¹s either by one or more ridges 0136 des-
cribed with reference to Figures 1 and 3, or by one or more double V grooves 070 in
the top face of the bottom plate ols. These latter will of course leave ridges upon
the respective side of the linotype but they will be removed by the trimming knife.
When the cap plate o" is moved up to the bottom plate o18, the core is separated
from the latter by a distance only just wide enough to pass metal for the linotype (26
into its mould cavity 0137. The metal flows into the latter between the ridges c",
on the ends of the core c. 138 is the mould cavity for the excess width above des-
cribed, sprue. Starting from the rear edge of the edge of the core c20, the mould
cavity o slopes rearwards away from its opposite side in the bottom plate ols, as
shown in Figure 11. 07, 071 are under-cut ridges standing across the sloped face of
the mould cavity o133, and adapted after the manner described with reference to the
ridge 136 in Figures 1 and 3, to hold the sprue to the cap plate o when the latter is
being moved away from the bottom plate o. The above mentioned slope on one
side of the cavity o3s produces an elevation on the cap plate o" along the junction of
the two cavities o¹s and o¹37 which has the effect of making the connection between
the linotype and the sprue so thin that they readily part by fracture along that
junction when the cap plate o17 is moved away from the bottom plate 18. Figure 5
shews the sprue parted or broken from its linotype and both still held to the
respective plate o, 17.
After both narrow linotype and its sprue have been cast, the mould wheel O is
moved through its are of 270° an the mould is opened by either of the devices
already described, thereby breaking the linotype and the sprue away from each other
along the junction of their respective mould cavities. This parting by fracture is
shewn in Figure 5. The ejector blade 0+ is then advanced and ejects the linotype C26
from the mould cavity o137, pushing it through the trimming knives into the galley.
The sprue is ejected by the studs 072, 072, which project laterally from the respective
side of the ejector blade O. They stand on the blade O far enough to the rear of
the nose of it to prevent them touching the trimming knives and eject the sprue to
one side of thein. The mould is then closed as the mould wheel moves through the
90° are into the casting position in the way already described.

tion and in what manner the same is to be perforined, we declare that what we
