TYPOGRAPHICAL CASTING MACHINE
George P. Kingsbury, Hollis, N. Y., assignor to
Mergenthaler Linotype Company, a corporation
of New York
Application December 12, 1935, Serial No. 54,034
22 Claims. (01. 199-49)
This invention relates to typographical casting
In recent years, there has been an increasing
machines, such as linotype machines of the gen
demand for ‘larger faces and, in attempting to
eral organization represented in United States
patent to O. Mergenthaler No. 436,532, wherein
5 circulating matrices are released from a magazine
in the order in which their characters are to ap
pear in print, and then composed in line in an
“assembler” or “assembling elevator”, the com
posed
line transferred from the assembler
10 through an “intermediate channel” into a ver
tically movable transporter or “?rst elevator”
which presents the line to the face of a slotted
mold, the mold ?lled with molten metal to form
a slug or linotype against the matrices, which
15 produce the type characters thereon, and the
matrices thereafter returned through distribut
ing mechanism to the magazine from which they
started.
‘
_
In the commercial machines, the matrices are
20 of standard form and dimensions and are com
monly provided on their casting edges with two
superposed characters, ranging in size from 5 pt.
to a maximum of 14 pt. The letter characters
on the individual matrices are usually alike, the
5 upper one being roman and the lower one italic,
and the matrices are composed at one or the
other of two different levels to bring either the
roman or the italic characters into casting posi
tion. After composition, the matrices are main
tained at their respective levels by means of rails
which support them by their projecting ears dur
ing their circulation through the machine from
the time of composition until after the casting
operation. ‘In the assembler, the matrices are
35 supported by their lower projecting ears on upper
and lower rails and they are similarly supported
in the intermediate channel during the line
transfer; but when the line enters the ?rst ele
vator, those matrices standing at the lower level
40 are sustained by their upper projecting ears on
a pair of upper ?xed rails‘ while those standing
at the upper level are supported by their lower
projecting ears on a lower (single) retractible
rail. After the casting operation, and when the
45 ?rst elevator is raised to the "upper transfer
position”, the retractible rail is moved forwardly
from beneath the matrices standing at the upper
level, so that they may drop to the lower level
preparatory to the transfer of the line onto the
50 second elevator bar.
'
The retractible rail is con
trolled by cam surfaces formed on a ?xed over
head bracket, which constitutes part of the
framework and just clears the top of the ele-,
vator when the latter is stopped in the upper
55 transfer position.
meet this demand insofar as “two-letter” mat
rices are concerned, many serious di?iculties have
presented themselves. Thus, the distance be
tween the top of the lower character to the top
of the upper character (characters inverted) of
5
a standard two-letter matrix is the same through
out the various fonts, and in order to increase
this distance for characters above 14 pt. without
disturbing the location of the upper character
so that the latter character may still register as
usual ‘with the mold slot, it is necessary to utilize
part of the regular space between the lower pro
jecting ear and the top of the lower character. 15
Consequently, when these two-letter matrices are
formed with characters above 14 pt., they must
be supported in the ?rst elevator at a. correspond
ingly higher level to bring their lower characters
into registration with the mold slot. Ordinarily, 0
the space between the lower projecting ear and
the routing notch for the lower character is
seven-thirty-seconds of an inch, and it has been
found that this space may be reduced to three
thirty-seconds of an inch, thereby giving four
thirty-seconds of an inch additional character
space.
This means that when such additional
character space is fully utilized, the matrices
(which will hereafter be referred to as “special”
matrices) will have to be'supported in the ?rst
elevator at four-thirty-seconds of an inch above
the normal upper level. In reaching this new
high level, undue wear on the lower projecting
ears of the matrices should be avoided, since they
present surfaces by means of which the matrix
characters are aligned with the mold slot. Fur
thermore, changes in the assembler, intermediate
channel and other organs of the machine should
also be avoided for obvious reasons.
The present invention is intended to overcome
these and other di?iculties and contemplates
means whereby thespecial two-letter matrices
may be assembled at the two normal upper and
lower levels and retained at those levels until
they come to rest in the transporter. Then, as
the transporter descends to the casting position,
it is proposed to raise those matrices standing at
the normal upper levelto the new or higher level
so that the lower characters, notwithstanding
their greatly increased size, will register with 50
the mold slot in the required manner (the datum
or constant line of the mold being the same as
usual). Here it may be noted that the upper
characters, although likewise of increased size,
will register with the mold slot while standing
2,074,511
2
at the normal lower level, since the datum line
of these characters (a line drawn through the
tops of the inverted characters) has not been
changed, as has the datum line for the lower
characters. After the casting operation, the
elevator head at the normal upper and lower
levels;

matrices are all brought to a common level pre
tory to the casting operation;

In the speci?c embodimentherein illustrated,
the retractible, rail of the ?rst elevator is em
10 ployed to support either the regular or the special
matrices by their lower projecting ears. When
regular matrices are in use, ‘the retractible rail
will function in the usual manner, but when spe
cial matrices are being handled, said rail is raised
15 automatically as the ?rst elevator (after receiving
the line at the normal levels) descends to present
the line to the mold. After casting, and as the
?rst elevator rises to its upper transfer position,
the rail is automatically restored to itsoriginal
20 lower position in readiness for the next composed
line, thus permitting‘ the special matrices sup
ported by it'to drop back to the normal upper
level at which they entered the elevator; and then
when the elevator ' reaches‘ the upper transfer
25 position, the rail is automatically withdrawn (as
in the customary way) 'to‘permit the matrices to
drop or be pushed ‘down to- the level of; the mat
rices standing at the lower normal level in the
elevator, whereby all of the matrices in the com
30 posed line are brought to a common level as usual
prior to the transfer of the line from the ?rst
elevator tothe second or distributing elevator.

,The regular matrices X and the special mat
rices Y are of standard form and dimensions, be
ing provided respectively with an upper pair of 3O
projecting ears s31, 11/1 and a lower pair of project
ing ears $2, 1112. On their casting edges, the mat
rices X and Y are each formed with two super
posed characters :03, 9:4, and 3/3 and 11/4, respec
tively, the characters 9:3 and m4 of the regular

matrices X having a range in size throughout the
various matrix fonts from 5 pt. to 14 pt., and the
characters 113 and 114 of the special matrices Y
having a range in size from 14 pt. up to, say,
20 pt. or 22 pt.
In Fig. 8 two of the regular and in Fig. 83 two 40
of the special matrices are shown standing at
their respective upper and lower casting levels
and in each instance with the lower character of
one matrix aligned With the upper character of
the other. It will be observed that while the

direction back to its original position. The
mounting of the rail is such that it is raised and
50
lowered in the required manner when thus shifted
3:2 and 112 of the matrices X and Y and the bot
tom walls of the routing notches containing the
upper characters 363 and 11/3 is exactly the same,
the space or vertical distance between the lower 50
ears g2 of the matrices Y and the bottom Walls
only when the machine is. handling the special
matrices, being rendered inoperative when the
regular matrices are in use, it being understood
that it is not intended to compose lines containing
both regular and special matrices. These auto
40 matic devices comprise,v generally, a projection on
the vise frame andia cam piece on the retractible
rail, these parts acting by their mutual engage
ment, as the ?rst elevator arrives in its casting
45
position, to shift therail endwise in one direction
endwise in opposite directions. -
The projection on the vise frame forming part
of the automatic devices referred to is in the form
of a pivoted block, which may be turned at will
55
into, and out of the path of the cam piece on the
space or vertical distance between the lower ears
of the routing notches containing the lower char
acters 11/4 is considerably less than that between
the lower ears m2 of the matrices X and the bot
tom walls of the routing notches containing the 55
lower characters m4. Consequently, both the reg
retractible rail, so that,-by a single manual ad- ' ular and special matrices may be supported at a
justment, the machine may be set for one kind of
matrices or the other, as desired. No changes
or alterations are required in the assembling ele
vator, ‘the intermediate channel, and the parts in
d the vicinity of ‘the upper transfer position.
' In the accompanying drawings, the invention
has been shown merely in preferred form and by
65 way of example, and obviously many‘changes and
variations may be madetherein and in its mode
of. operation without departing from its spirit.
It should be understood, therefore,’ that the in
vention is not limited to any speci?c form or em
70 bodiment, except insofar as such limitations are
speci?ed in the appended claims.
Referring to the drawings:
Fig. l is a side elevation, partly in section, of a
portion of the improved ?rst elevator and show
ing a line of the special matricessupported in the
common lower level to locate their upper charac
ters in casting position, but must be supported at
relatively different upper levels to locate their 60
lower characters in casting position, the matrices
X to stand at the normal upper level and the mat
rices Y to stand at the higher or new level, as
indicated.
.
In the normal operation of the machine, the
composed line of matrices is transferred, as usual,
to the vertically movable ?rst elevator or trans
porter A (Fig. 1), wherein the matrices composed
at the lower level will be supported by their up
per projecting ears on a pair of ?xed horizontal
rails a, and those composed at the upper level
will be supported by their lower projecting ears
on a single retractible rail B. Upon receipt of
the line, the ?rst elevator descends until it banks
upon a vise frame C (Fig. 2) and in this way po

placement, it is at the same time, and for reasons
presently to appear, capable of a limited fore
and-aft movement from and to its normal matrix
supporting position shown in Figs. 1 and 2. Ad
ditional vertical support is furnished the bracket
piece G between its ends by a shoulder screw g3,
which passes upwardly through an angular slot
94 of the piece G and is threaded into the bottom
10
of the front side wall A3 (Figs. 3 and 7).
The fore-and-aft movement of the bracket
piece G is effected by a pair of vertical levers
A6 mounted on pivot studs (1.3 in recesses formed
in the front side wall of the elevator head A2
near the opposite ends thereof. At their upper
ends, these levers are provided with beveled nose
portions (1.4 and, between the nose portions and
the studs 09, they are connected by pull springs
A7 to the body portion A1 of the elevator (Figs.
1, 2 and 6). At their lower ends, the levers A6 2-0
engage in elongated apertures b1 formed in the
rail bar B1 (Figs. 3 and 7) and, through the con
nection of said bar with the tongues g of the
bracket piece G, hold the latter as well as the
bar B1 under tension of the springs A'’ in their
matrix supporting or unretracted position
in the vise frame.
_
The mold D (Fig. 2) comprises, as usual, a body
portion D1, a cap portion D2, and a pair of inter
mediate liners D3, the cap and body portions
forming the upper and lower side walls of the
mold slot and the two liners the end walls there
10 of. The body portion D1 of the mold D also pre
sents a pair of upper and lower aligning ribs D4
and D5, respectively, which are positioned di
rectly over and in engaging relation to the lower
projecting ears of the matrices when the mold
carrier F is advanced to force the mold against
the matrix line for the casting of the slug‘. In
this connection, it may be mentioned that due
to the higher level at which the matrices Y must
be supported in the ?rst elevator to bring their
20 lower characters into casting position, the upper
aligning rib D4 of the mold D (which is intended
only for the special matrices) is made propor
tionately thinner than the corresponding rib on
the regular mold used for the regular matrices X.
After the casting operation and the mold recedes,
the ?rst elevator is raised to the “upper transfer”
station (Fig. 6), where the matrices are caused
to assume a common level, and the line is then
against stop shoulders a5 (see Figs. 1 and 2)‘.
However, by pushing the upper ends of the levers
shifted horizontally by a transfer slide 0 onto
the second elevator bar (not shown), which car
ries the line upwardly to the distributing mecha
A6 backwardly (which is done when the ?rst
elevator rises to its upper transfer position as 30
tnism.
As: best shown in Figs. 1 and 2, the ?rst eleva
tor A includes the long vertical body portion A1,
which is slidably mounted in the vise frame C,
and the improved head portion A2 which com
prises, as usual, the front and rear side walls A3,
A4, and the intermediate connecting block A5
(Figs. 3 and 4) arranged at one end of the eleva
shown in Fig. 6), the bar B1 and bracket piece
G will be moved forwardly in opposition to the
springs A" and thus carry the rail B and lip g1
to the matrix levelling or retracted position
indicated.
A smoother action to the piece C
during its reciprocations to and fro is assured
by arranging the upper ends of the tongues g

40 tor head. The ?xed rails a are formed integrally
' The rail bar B1 is moved endwise toward the 40
with the front and rear side walls A3, A4; where
as, the retractible rail B is formed on a bar B1,
which is arranged below the front wall A3 and,
according to the present invention, is mounted
45 for vertical adjustment on a pair of ?xed tongues
g rising from a supporting bracket piece G.
For a purpose later to be pointed out, the bar B1
(Figs. 3, 4 and 5) is provided with an upright
plate B2 secured to the front edge thereof and
presenting an elongated cam surface B3. The
plate B2 is arranged flush with the front face of
right by a pull spring B4, which is connected
the side wall A3 in a recess ‘a1 formed therein, so
as to escape the vise frame when the ?rst eleva
tor descends to casting position.
The tongues 9' (Figs. 3 and e) present inclined
upper and lower edges 91 and have a sliding ?t
in corresponding slots or apertures b formed in
the rail bar B1, so that by moving the bar B1
endwise in opposite directions it will be cammed
60 upwardly and downwardly by the inclined sur
faces gl. The amount of adjustment required in
55
a vertical direction for the rail B is so slight
that the inclination of the surfaces g1 may be
very gradual (about twenty degrees), and hence
said surfaces may absorb most of the downward
pressure on the rail during the normal machine
operation of aligning the matrix characters with
the mold slot. This pressure will be trans
mitted to the front wall A3 of the member A2
70 through the bracket piece G, which is sustained
‘ by means of integral upright end portions G1
from said wall. The end portions G1 are pro
vided with lateral fore-and-aft ribs or ?anges
92, which engage in corresponding slots 0.2
formed in the wall A3, so that while the bracket
to the bar at one end and is anchored in a
clearance slot g5 formed in the bracket piece
G (see Figs. 3, 4 and 7). The bar B1 will thus
normally be held in its lowermost position, 45
wedged by the tongues a down upon the piece
G under the influence of the spring 132 (see Figs.
1 and 3). In such position, the rail B will be
properly located to give support to either the
regular matrices X or the special matrices Y 50
as they are delivered to the ?rst elevator at the
normal upper level, the matrices X being main
tained at that level by allowing the rail to re
main at rest during the descent of the elevator,
and the matrices Y being raised to the higher 55
or new level required (see Figs. 2 and 4) by
adjusting the bar B1 a given distance upwardly
and toward the left along the beveled surfaces
of the tongues g during the descent of the ele
vator. To prevent other matrices Y of the line
which may stand at the lower level in the ele
vator head A2 from possible displacement verti
cally through frictional contact with those being
raised, the bracket piece G (Figs. 1 and 2) is
provided with a retaining lip g6, which projects 65
from the rear edge thereof above the lower pro
jecting ears y2 of said matrices.
Means are provided for elfecting the endwise
movements of the rail B automatically, so that
lines of the special matrices Y may be cast suc
cessively in the usual way without attention on
the part of the operator or interruption in the
normal operation of the machine. Such means
(see Figs. 2 to 5, inclusive) consists of a small
semi-circular block H, which presents a high con

best shown in Fig. 2, the block H is pivotally

When the block H is turned to its inactive
15 position (as in Fig. 5), the high surface 71.
thereof will be disposed out of the path of the
upright cam plate B2, so that the latter will
escape contact with the block as the ?rst elevator
banks upon the vise frame and thus permit the
20 rail B‘ to retain its lower or normal position
(shown in Figs. 1 and 3) where it is adapted to
serve as a support for regular matrices X com
posed at theupper level.

70 combination of a vertically movable transporter
provided with a vertically adjustable matrix sup
porting rail, a vise frame for supporting the
transporter in its lowermost or casting position,
and an actuating block mounted on said vise
frame and arranged to cooperate with the rail
in e?ecting its vertical adjustment.
17. A combination according to claim 16,
‘wherein the actuating block is movable to active
or inactive position as desired.
18. In a typographical casting machine, the
combination of a line transporter movable from
line receiving position to line casting position,
then from line casting position to line transfer
position and ?nally back to line receiving posi 10
tion, said transporter being formed with a pair of
?xed matrix supporting rails and with a re—
tractible matrix supporting rail, and said retract
ible rail being vertically adjustable from and to
normal matrix supporting position in the trans 15
porter.
