PROVISIONAL SPECIFICATION.
Improvements in and relating to Machines for Casting Type,
Linotypes, and other Units of Composite Printing Surfaces.
I, JOHN PLACE of No. 188 Fleet Street, in the City of London, Engineer, do
hereby declare the nature of this invention to be as follows:-
The present invention relates to improvements in and relating to machines for
casting type, linotypes and other units of composite printing surfaces and the
object of it is to expedite the rate at which the said units are produced as well
as to endow a machine of a given size with a capacity of production considerably
in excess of that of which it is capable so long as its construction is restricted to
the principles hitherto followed.
It consists broadly in combining with a single metal injecting pump, several
series of moulds, as many delivery jets, and mechanism for presenting one mould
of each series to the respective delivery jet, at one and the same time as well as
mechanism for working the pump and ejecting the cast units, the delivery jets
being brauched from the pump and terminating in as many jets as there are
series of moulds in order that each working stroke of the pump may fill oue
mould in each series.
Consequently, the invention is applicable to linotype machines as well as to
type casting machines.
I have chosen its embodiment on one of the latter for specification, as that will
best set forth the nature of the invention.
I prefer to arrange the moulds in tiers around a turret, the tiers being then in
horizontal planes parallel with each other so that the molds in the respective
tiers may register one by one with the metal jet intended to supply them."
The matrices proper are at the opposite ends of the moulds. The metal jets and
the matrices proper may be respectively on or near the outside of the turret or at
the opposite ends of the moulds, being then arranged within or communicating
with or operated from a central opening in the turret.
The ejecting mechanism and the co-operating galleys or races may be of any
suitable kind.
The turret arrangement above described is preferable because of the continuity
of circular motion, as compared with linear motion but the invention does not
restrict me to it, as the turret and its circular motion may be replaced by a
rectangular block having the moulds in it, and by a reciprocating linear motion.

page_text: Improvements in and relating to Machines for Casting Type,
Linotypes, and other Units of Composite Printing Surfaces.
I, JOHN PLACE of No. 188 Fleet Street, in the City of London, Engineer, 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 present invention relates to improvements in that class of machines for
casting type, in which the moulds are arranged in a rotating wheel or drum, and
includes the adaptation of the improvements to the casting of linotypes and other
units of a composite printing surface. The object of it is to expedite the rate at
which the said units are produced, as well as to endow a machine of a given size
with a capacity of production considerably in excess of that of which it is capable
so long as its construction is restricted to the principles hitherto followed in the art.
The invention consists in a particular and distinctive combination of several tiers
of moulds, as many metal delivery jets, mechanism for presenting one mould of
each tier to the respective delivery jet at one and the same time, a series of matrices
corresponding in number and respective position with the metal delivery jets,
mechanism for presenting the series of matrices to the opposite ends of the said
moulds at the same time that the latter register with the metal delivery jets, and
an ejecting mechanism distinct from aud not connected with the series of matrices.
I prefer to arrange the moulds in tiers around a turret, the tiers being then in
horizontal planes parallel with each other, so that the moulds in the respective
tiers may register with the respective metal delivery jets.
The turret arrangement just described is preferred because of the continuity of
circular motion as compared with the intermittence of reciprocating linear motion,
but it must be distinctly understood that the invention does not restrict me to
it but includes the substitution of a rectangular block having the moulds in it and
working with a reciprocating linear motion past the metal delivery jets, for the
turret with its continuous circulur motion.
Whether the invention is embodied in a machine for casting type, in one for
casting linotypes, or in one for casting any other units of a composite printing
surface, affects only the size and nature of the matrices, the size of the moulds,
and the size of the ejecting devices-the invention itself remains the same. Both
type casting machines and linotype machines have been known in this country
sufficiently long to make persons skilled in the art to which this invention belongs,
proficient in the distintive features of the casting and ejecting mechanisms of
them both. Such being the case, if a machine for casting linotypes is to be con-
structed according to the present invention, any ordinary mechanic will find
himself able to adopt the details of the casting and ejecting mechanisms of the
well known Mergenthaler Linotype machine -vide Specification of Letters Patent
14582 1890. If on the other hand, the machine is to cast types, the simpler
mechanisms of any type casting machines may be employed.
I have selected for illustration, the embodiment of the invention in the respective
members of a machine for casting type. But for the sake of emphasizing the
fact that the invention is not limited by the dimensions or nature of the thing cast,
the latter is designated by the generic term "unit," instead of by either of the
more specific terms "type" or "linotype."
Figure 1 is a diagrammatic sectional illustration, and
Figure 2 is a diagrammatic sectional plan corresponding therewith.
d' is the turret. It is supported upon a horizontal base upon which it is
rotated with an intermittent or step by step motion by any suitable mechanism.
dis an annular guide for the said motion. It consists of a ridge projecting

page_text: from the top of the base and engaging the turret by standing in a corresponding
groove in the bottom thereof.
d, d are the moulds. There are four tiers indicated in the figures, but only
two series are illustrated. These two are shewn in plan in Figure 2. There
may be as many tiers of moulds as may be desired, the depth of the turrets being
modified accordingly. There may be as many series of moulds as may be desired,
the circumference of the turret being modified accordingly. The moulds of each
series stand over each other, and preferably vertically over ecch other as shewn
in Figure 1.
r is the mouth piece of the pump. This latter may be either a fixture or it
may be mounted so as to move up to the outer face of the turret side in time
for ecch casting operation, being afterwards meved away therefrom, after the
manner described in the above mentioned Specification 14582 1890; or it may be
stationary. In either case the front of the said mouth picoe in arcual, being struck
to the same radius as the said outer face of the turret side, both being finished
off so that when, and so long as, they are in contact, they shall fit metal tight to
each other, the mouth piece r then olosing all the moulds d in the series opposite
it. 0,0, are the metal delivery jets from the pump. They correspond in
number and respective position with the tiers of moulds d'.
dds are the matrices of one series. There is only one series in use at one
time with one series of jeta 10, The several matrices of a series correspond in
number and position with the moulds d' of a series, and are fast to the face of a
matrix carrying block . This latter occupies a position within the turret d'.
The front face of the Mock is arcual, bring struck with the same radius as
the inner wod opposite face of the turret side, and both are finished off so that
when, and so long as, they are in contact, they shall fit metal tight to each other,
the said face of the mould block closing all the moulds in the series opposite.
The length of one movement of the turret d' is equal to the distance of one
series of moulds from the next, centre to centre. During such movement, the
block must be moved away out of contact with the turret side, and back again
so as to contact with it agnin over the following series of moulds. The necessary
reciprocating radial movement of the block de is imparted to it by the combination
of a constantly rotating vertical shaft d standing up through the base and the
bottom of the turret ; a horizontal disc eccentric de about the said shaft and
having a groove d of the proper eccentricity in its top surface; a foot on the
block d fitted with an antifriction roller dlo to engage in, and to be engaged
smoothly by, the groove d; a horizontal socket on the top of the shaft d
and a horizontal arm a fast to and projecting from the block and fitting with
a sliding fit within the socket ". The shaft d rotates about its axis once during
que movement of the turret d. Either the disc eccentric or the socket dil
may be fast to the shaft d, but one of them must be held stationary. If the disc
eccentric is fast, the block de makes only a reciprocating radial movement.
If the socket d is feat, the block d makes a rotary motion about the axis of the
shaft in addition.
The step by step movement of the turret d' which has just beon described may
be replaced by an intermittent eiroular one, each rotation bringing up two series
of moulds d into the position illustrated in Figure 2. In this case the turret d,
disc eccentric d, and socket d would revolve with the shaft d. Such an arrange-
ment would permit of the series of moulds differing among themselves in size,
the turret d'and eccentric being adjustable upon the shaft d' so as to bring
any one series into working position.
The ejecting mechanism consists of a series of ejectors of the well known con-
struction and distinct from and not connected with the series of matrices . I
prefer that the series of moulds first filled with metal shall move away from,
instead of next up to, the ejecting mechanism, in order that the freshly cast unita
may have a fair chance of cooling thoroughly by radiation or otherwise. dis
is a unit receiver, It cousists of a vertical arrangement of holes d" each one

page_text: large enough to contain one unit. There is combined with this receiver suitable
mechanism adapted to present it to the series of moulds to be emptied, where-
upon the ejectors push the units out of the said series into the respective holes d
The receiver is then moved away and in its turn has the units pushed out of
its holes. The act of ejection of the units from one series of moulds takes place
whilst a cast is being effected in anether.
,, are vertical air passages in the turret side between the series of moulds,
to facilitate cooling of the latter and their contents.
The motion of the turret is spoken of above as circular. This must be under-
stood in the sense of circular as distinguished from the reciprocating linear
motion of the rectangular block described as an alternative for the turret. In
neither case would the motion be absolutely continuous. It must be intermittent
the series of moulds standing still during the act of casting, and possibly again
during the act of ejection according as to whether the actual ejectors work from a
base of operatious independent of the turret or are carried by it.
When the turret d is replaced by a rectangular black, the front of the mouth
piece and the face of the matrix block do are parallel with the respective sides
of the said rectangular block. The series of moulds in the latter are parallel instead
of radial and the mechanism for imparting the to and fro motion to the matrix
block d is modified accordingly.
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:
1. The hereinbefore described combination of moulds in tiers and series, having
an intermittent motion with reference to a series of matrices and a series of metal
delivery jets; a series of matrices having a to and fro motion with reference to
the then stationary series of moulds and adapted to register with the said moulds
at one end thereof; and a series of metal delivery jets adapted to register with
the then stationary series of moulds at the other ends thereof.
2. The herein before described combination of moulds in tiers and series; as
many metal delivery jets as tiers of moulds; a series of matrices corresponding
in number and position with the metal delivery jets; mechanisms for presenting
one series of moulds between the series of metal delivery jets and the series of
matrices and the three series metal tight to each other at a time; and an ejecting
mechanism distinct from and not connected with the series of matrices, adapted
to push the units from one series of moulds during the time that all the moulds are
standing whilst a cast is effected.
3. The hereinbefore described combination of turret having moulds in tiers
and series; mechanism for moving the said turret and moulds with an inter
mittent or a step by step rotary motion; a series of matrices; & series of metal
delivery jets; a series of ejectors; mechanism for making the matrices register
with the stationary series of moulds; and mechanism for making the series of
ejectors act on the units in another stationary series of moulds.
4. The hereinbefore described combination of rectangular block having moulds
in tiers and series; mechanism for moving the said rectangular block with an
intermittent or a step by step reciprocating linear motion; a series of matrices;
a series of metal delivery jets; a series of ejectors; mechanism for making the
matrices register with the stationary series of moulds; and mechanism for actuat-
ing the scries of ejectors or the unit in another stationary series of moulds.
