4 Claims. (Cl. 199-53)
The present invention relates to a 'guard for
mold disc ll is mounted on a shaft I2 and is
use on Linotype machines ’for preventing the
provided with Water compartments, not shown,
spattering of molten metal during the casting of
for cooling purposes.
a blank or typographed slug.
As is well knownl in the art after the matrice
are set in a line, the line is carried to an ele
vator for supporting the same and carrying said
line to the casting part of‘the’machine. The
casting is accomplished thru the use of a pot
containing molten metal, and in the casting op
eration the molten metal is squìrted thru a re
stricted opening into the mold. The squirting
of the metal presents a hazard to the operator
of the machine since it frequently occurs that
_ the metal will spatter, which is caused primarily
when the matrices are loosely held or when they
become worn, when the line is improperly justi
fied, when the metal is too hot or too cold, when
The elevator mechanism for holding the mat
rices during the casting operation and for trans CFI
porting to and from the casting operation is indi
cated generally by the numeral I3, and comprises
a longitudinal frame I4 and channeled rails I5.
The channeled’rails I5 support the matrices I6
and space band I'I as clearly illustrated in Fig. l0.
l of the drawing. The justification mechanism
is indicated generally by the numeral I8. The
elements above described comprise a portion of
the usual Linotype machine with which the
guard is associated.
The guard indicated generally by the numeral

I9 is attached to a portion of the machine 20
known as the ñrst elevator stop, at which point
the line of type is transferred to the distribut
ing or second elevator, not shown. 'I‘he guard I9
is attached thru the bracket 2| being secured
thru bolts or the like 22, said bracket being
pivotally connected at 23 to permit the guard to
swing into and out of engagement with the ma
chine. By referring to Fig. 3 0f the drawing it
will be noted that the guard is formed of a chan
nel-shaped frame 24 that is substantially rec
tangularshaped. A shatter-proof glass 25 is
supported Within the frame on the front, top,
and two sides thereof, it being understood that 30
the back portion contacting the machine is open
tor mechanism should the occasion arise.
The invention will be fully and comprehensively
the side toward the operator there is provided
understood from a consideration of the follow
35 ing detailed description when read in connection
be necessary for the operator to have access to
small fragments of metal adhere to a matrice
2() or space band, when space bands slip off the jaws
which causes an opening therebetween, or when
a proper lockup is not obtained.
The primary object of the invention therefore
is to provide a guard connected to a Linotype
25 machine and so positioned that the operator of
the machine will be protected from the spatter
ing molten metal during the casting operation.
A further object of the invention is the pro
vision of a guard means for yprotecting the op
30 erator from spattering molten metal and at the
with the accompanying drawing.
Fig. 1 is a side elevation, partly in section, of
a Lintoype machine in position for casting a type
slug, the guard being shown in protective posi
40 tion.
Fig. 2 is a front elevational View and illus
trating the casting elevator with the guard in
position; and
Fig. 3 is a perspective view of the guard de
45 tached from the machine.
Referring to the drawing for a more detailed
description thereof, the Linotype machine herein
illustrated consists, briefly, of a pot 5 containing
molten metal, and having a spout 6 thru which
50 the molten metal is ejected into the slot 'l of
the mold B. The pot 5 is supported on the
main frame 9 and adapted to pivot thereon thru
the arm IE), the pivotal connection not shown.
Intermediate the pot 5 vand the frame 9 is the
55 mold disc II which supports the mold 8. The
as well as the end.
a hinged door 26.
On one side and preferably
For various reasons it may
the casting mold and surrounding parts and»
it is for this purpose that the door 26 is provided.
It will also be noted that the lower end of the
door is L-shaped as indicated at 2'I thru which
extends the adjusting mechanism, not shown, for
varying the measurements of the line to be set.
The L-shaped portion 2l permits the positioning
of the adjusting mechanism and .at the same time
allows for the guard to completely surround the
mold and casting parts to protect the operator 45
from spattering metal. The bracket 2| is also
provided with vertical slots 28 thru which the
bolts or the like 22 pass for attachment of the
guard to the machine, and by means of said
slots the guard can be adjusted toward and CIK
away from the channel rail l5, being adapted to
move a limited distance within said slots.
From the above description it will be apparent
that there is provided a new and novel type of
guard which protects the operator of a Linotype
machine from the spattering of molten metal
during the casting of a blank or typographed
slug. The provision of the guard does not in any
manner interfere with the normal operation of
the machine since all parts are visible and
readily accessible.
It is to be understood that this improvement
is capable of extended application and is not
conñned to the exact showing of the drawing
nor to the precise construction described and,
therefore, such changes and modifications may
be made therein to fit different models of type
casting machines as do not affect the spirit oil
the invention nor exceed the scope thereof as
expressed in the appended claims.
What is claimed as new is:
1. The combination with a machine for casting
type bars, comprising a holder for type matrices,
a mold cooperating therewith, and means for
forcing molten metal into a mold, of afn’ormally20
