MEANS FOR CHANGING THE lVIAGAZINES
OF TYPOGRAPHICAL COMPOSING MA
C‘HINES
Richard Henry Scott, En?cid, England, assignor
to Linotype and Machinery Limited, London,
England, ‘a registered company of England
Application February 10, 1937, Serial No. 125,029
.
In Great Britain February 14, 1936
7 Claims.
This invention relates to means for changing
the magazines of typographical composing ma
chinesof the kind wherein a column of super
posed magazines is adjustable between distribut
ing mechanism and assembling mechanism to
bring a selected magazine, or selected magazines,
into operative relationship with the said mecha
nisms, or to bring a selected magazine into a
position in which its delivery end is located above
the assembling mechanism to enable the maga
zine to be removed frontwise over the assembling
mechanism.
’
More particularly, the invention relates to ma
chines comprising an adjustable magazine-sup
15 porting frame including a plurality of base~frame
members one appropriate to each magazine of
the column, and a ?xed frame having side mem
bers between which the magazine supporting
frame is adjustable.
The object of the invention is to provide im
20
proved means for supporting during removal any
magazine of the column selected for removal by
adjustment of the column, and which is auto
matically brought into active position for sup
porting the magazine at the front of the assem
2
bling mechanism through the forward move
ment of the selected magazine.
With this object in View, the invention con
sists in a typographical composing machine pro
30 vided with an adjustable column of magazines,
comprising, on a ?xed frame in which the column
of magazines is adjustable, extensible arms
adapted to provide support, during removal, for
the magazine which is, for the time being, in the
35 plane of said arms.
The invention will be clearly ‘understood from
the following description of one form which it
may assume (given, however, merely by way of
example), and the description will be more easily
40 followed by reference to the accompanying
drawing, wherein:—
Figure 1 represents a side view, and
Figure 2 represents a plan View, of the relevant
parts of magazine supports in a typographical
45 composing machine according to the invention;
Figure 3 represents a section along the line
A--A of Figure 2, and
Figure 4 represents a detail modi?cation which
may be employed in a device as shown in Fig
30 ures l and 2.
In carrying the invention into effect in one
convenient manner as shown in the drawing
herewith, a rail I parallel with the magazines
is secured along each inner side of the ?xed
55 frame and a magazine supporting arm 3 is
(Cl. 199-46)
mounted to slide against the inner side of each
such rail I. For this purpose each arm 3 is
formed at its upper end with an outwardly offset
portion 4 dovetailed or grooved to embrace the
top and bottom edges of the rail 1.
5
The lower end of each arm 3 is formed with
an extension 5 offset inwardly, the upper sur
face of said extension having a groove 6 ?ared
at its upper end, as shown, and located in align
ment with a lug l on the respective side of the 10
adjacent magazine of the column.
The grooved
extension 5 of each arm terminates in a hook 8
which arrests the forward movement of a mag
azine being removed and permits such magazine
to hang from the arms in a vertical position as 15
shown in Figure 1.
The rail 5 is provided at its lower end with a
stop 2 serving to limit the downward movement
of the arm by engagement with the outwardly
offset portion 4 at the upper end of the arm.
20
Each rail i also carries at its upper end a latch
or detent 9 which normally retains the respective
arm in its innermost position.
When it is desired to remove a magazine, the
magazine supporting frame is raised or lowered 25
to bring the desired magazine into the plane of
the arms 3, and the operator slightly tilts the
magazine at its front end to disengage a cross
bar such as It on its underside from a recess H
in the base frame, and draws the magazine 30
downwardly over the base frame until its lat
erally projecting lugs "I" engage with the grooves
6 in the lower part of the arms and contact with
the hooks 8 thereof.
Further withdrawal of the magazine causes the 35
arms 3 to move outwardly therewith, the weight
of the magazine thus being transferred during
the forward movement from the base-frame to
the supporting arms. When the arms have
reached the limit of their outward position as 40
determined by the stops 2 at the lower ends of
the rails, the magazine is clear of the magazine
column and free to pivot in order to hang ver
tically from the hooks of the supporting arms.
The ‘reverse operation takes place during the 45
replacement of a magazine, except that the sup
porting arms 3 do not necessarily follow the
rearward movement of the magazines, and may
be returned to normal position by hand.
When the invention is applied to machines 50
?tted with split magazines, (and more especially
when this form of magazine is in any position
in the column except at the top) it has been
found that there is some danger in drawing for
ward the front portion of the magazine for re 55
2

moval, that it will slide off its supporting frame
before the lugs have properly engaged the grooves
6 for support. In order to avoid this danger
the arms 3 may be modi?ed as shown in Fig
ure 4. In this arrangement there is mounted
upon a pivot l l on the outer side of the offset
portion 5, or on the arm 3 adjacent thereto, a
platform I2 which can be swung by hand to the
position shown in full line, and thus provide
intermediate support when the front portion of
?xed frame, and. arms on said ?xed frame for
supporting one or another of said magazines
during removal or insertion, a slidable or tele
scopic member of each arm being adapted for
engagement by, and outward movement with, a
selected magazine being removed.
3. A typographical composing machine com
prising a ?xed frame, a plurality of magazines
in a supporting frame movably mounted in said
?xed frame, and arms having parts in slidable 10
a split magazine is being removed. When the
arm is in its innermost position the platform I2
engagement with a rail of said ?xed frame, adapt
ed to support one or another of said magazines
‘is swung forwards to rest over the offset portion
5 as shown in dotted lines in Figure 4. When
15 in this device a full size magazine is being re
during removal or insertion.
4. A typographical composing machine com
prising a ?xed frame, a plurality of magazines in
a supporting frame movably mounted in said
moved, the platform must clearly be swung to
the back (full line) position before the lugs 1
can enter the grooves 6, but this need not be
done until the arms 3 have reached the outer
20 most position determined by the stops 2 as the
lugs bear against the edges of the platforms I2
(in the position represented by dotted lines)
and thus move the arms.
It must be understood that the invention is
25 not restricted solely to the constructional de
tails of the forms described above, since various
modi?cations may be introduced as they become
desirable or necessary in order to carry the in
vention into effect under diiferent conditions and
30 requirements which have to be ful?lled, without
departing from the scope of the invention.
Having described my invention, I declare that
what I claim and desire to secure by Letters Pat
ent is:
1. A typographical composing machine pro
vided with an adjustable column of magazines,
comprising, on a ?xed frame in which the column
ofv magazines is adjustable, extensible arms
adapted to provide support, during removal, for
40 the magazine which is, for the time being, in the
plane of said arms.
2. A typographical composing machine com
prising a ?xed frame, a plurality of magazines in
a supporting frame movably mounted in said
?xed frame, and arms on said ?xed frame for
supporting a magazine during removal or in
sertion, a slidable or telescopic member of each
arm being adapted for engagement by, and out
20
ward movement with, a magazine being removed,
and grooved members on the outer ends of said
arms adapted to receive lugs projecting from the
magazine being removed.
5. A typographical composing machine as 25
claimed in claim 2, wherein said arms have hook
like extremities in which a magazine can pivot
in its outermost position.
6. A typographical composing machine pro
vided with an adjustable column of magazines, 30
comprising, on a ?xed frame in which the col
umn of magazines is adjustable, extensible arms
adapted to provide support, during removal, for
the magazine which is, for the time being, in
the plane of said arms, and auxiliary supporting 35
means positionable between the foremost sup
porting part of the magazine base, and the sup
porting elements of said arms.
7. A typographical composing machine accord
ing to claim 6, wherein said auxiliary means
comprise platforms pivotally attached to said
arms.
