This invention‘relates to typographical com
column, consisting of any desired number of
posing machines.
In such machines having’ a plurality of maga
zines arranged in superposed relation as’ a col
umn, it is usual to employ matrix entrance chan
nels (hereinafter called magazine entrances) ca

6 mounted on a shaft 1, and the shaft 1 carries
a handle 8 so that by turning the handle, the
magazinesrwill he adjustedgto different levels. 15
When changingover from one magazine to anoth
er, it’ is necessary for the shaft 1 to be turned to a
rotary change-over of the magazine entrances certain extent, (preferably to- the extent of one
to a particular magazine arrangement, ithas whole revolution for. changing from one maga
20 been proposed, when using a rack bar andpin
zine to the next), and in. order tobe able to lock. 20
In order to allow application of this automatic
ion’mechanism for the rotary change-ovento
make the rack bar interchangeable and to ?t it
to the magazine arrangement in use for the time
being. This arrangement makes it necessary
25 however to have different rack bars always avail
able and to interchange them when required.
The object of the invention is to overcome
these disadvantages in the known arrangements,
and to make the rotary change-overof the magae’
zine entrance entirely independent of the maga
zine change. According to one embodiment of
the invention the locking and the change-over of
the magazine: entrances, joined together into a
rotatable unit, is effected by the movement of a
handle, ‘operating the release of the magazine
shift, beyond the extent required for releasing
the magazines.
In the drawings, one constructional form of
the invention is illustrated by way of example,
4:0 and in the said drawings:—-

In the construction illustrated in the draw
ings, i is the machine frame, and 2 the magazine
the shifting frame after each shifting opera
tion, a disc 9 is mounted upon the shaft 7 and
carries on its periphery} a notch, in which engages
a ledge l9’ mounted. on a lever 52 ‘adapted to.
swing about a stud l i on the magazine frame. 25
Upon a pivot‘ i3 is located a three-armed lever,.
one arm ill of which is formed as a handle,_the
second arm 65 is articulated to a draw-rod l5.‘
and'third arm ll consists of a segmental por
tion, which is adapted to bear against a roller 50
i8 mounted on the lever l2. The lever i2 is also
provided with a cam is serving to move a lever
29, ?tted with a roller, which is loosely mounted
on the shaft l3 and serves to rock the releasing
rods 2| which operate the release of the matrices 35
from the magazine, but which must be moved
away from the magazines before the latter are
shifted. When therefore the lever I4 is swung
clockwise, i. e., when it is raised, the segment I’!
bears against the roller 28 and swings the lever 40
12, moving the ledge iii out of the slot of the disc
9 and thereby release. the shaft 1. Atlthe same
time the cam 59 acts against the: lever 25 and
swings the matrix releasing rods 2i away from
the magazine, so that the shifting of the maga- 45
zine can proceed.
According 'to the invention, ‘further rocking
movement of the said handle I ll causes the re
lease and the rotary change over of the maga
zine entrances,v and as shown this is effected by 50
means of the rod l6 attached to the lever arm
15. This rod i5 is linked by means of a stud 22
to a double lever 23 Which'is adapted to rock
about the pivot 24 located on the lever 25, the
lever 25 being itself capable of swinging about 55
' 2
a pivot 26.
On the lever 25 are two abutment
screws 2?, 28, which limit the rocking movement
of the lever 23 about its pivot 24.
Upon the shaft 26 is also mounted a toothed
CI wheel 29 which is in mesh with a toothed wheel
(ill, fast on the shaft 3| upon which is also ?rmly
secured the support 32 for the two magazine en
trances 33, 34. The shaft 3| is located. on a
swinging arm 35 which is adapted to rock about
10 a stationary stud 36 on the machine frame. On
leasing wrods return into their operative position,
enabling the compositor to proceed with his work.
It should be understood that the principle un
derlying the invention consists in arranging
means common for the operations of shifting the
magazines and of changing-over the magazine
entrances, so that these operations can be carried
out independently and in particular so that the
magazines can be shifted without necessarily
changing the magazine entrances. Within the
the same arm 35 is also located the stud 26, and
a further pivot stud 3'! for a double lever at
terms of this principle various modi?cations of
the form of the invention described above may
one end of which is attached a spring 38 whereas
the other end carries a pin 39. The latter, un
der the action of the spring 38 is capable of en
tering a recess 40 in a disc 4| positively secured
be introduced in order to meet different condi
tions and requirements which have to be ful?lled,
upon the shaft 26. A detent 45 also adapted to‘
engage in the recess 40, is pivotally mounted
upon a shaft 24 and by a spring, not shown in the
drawings, is pressed against the disc 4|. A stud
42 is also provided on the machine frame to come
without departing in any way from the scope
of the invention.
Having described my invention, I declare that
what I claim and desire to secure by Letters
Patent is:—
1. A typographical composing machine having 20
into contact with an abutment 43 on the arm 35
magazine entrances, wherein means common to
in order to limit the swinging movement of the
the operations of shifting the magazines and
arm 35 about the stud 36.
changing the matrix entrances are so arranged
as to allow said operations to be effected inde 25
The mode of operation of the present arrange
ment is as follows:—
When the operator desires to shift the maga
zines he ?rst swings the handle I 4 in order to
release the shifting mechanism. When the lever
30 I4 is raised to a certain extent the shifting shaft
‘l, as previously mentioned is released and the
escapement rods 2| moved away from the maga~
zine. Simultaneously, however, and by reason
of the pull exerted by the rod It, the arm 35,
35 which is held in its operative position by a very
light spring 44, is rocked until the abutment 43
comes into contact with the pin 42. When the
parts are in the said position, the shifting of the
magazines can be effected in the usual manner
40 without adjusting the magazine entrances. If it
is necessary to change-over the magazine en
trances, the operator swings the lever I4 clock
wise a little further. The pull exerted by the
rod l6 rocks the lever 23 about its pivot 24. A
rotation of the lever 25 about its pivot 26 does
not occur because, in consequence of the engage
ment of the locking pawl 45 with one of the
grooves 49, it is engaged with the disc 4| and the
latter is locked against rotation by the pin 39.
When, however, the lever 23 is rocked, the free
arm of the lever bears against the pin 39 and
raises the latter out of its locking position. The
parts then occupy the position shown in Figure 3
pendently irrespective of the number and relative
arrangement of the magazines.
2. A typographical composing machine having
adjustable magazines and interchangeable maga
zine entrances, wherein means for unlocking the
magazine shifting mechanism are adapted, upon
being moved beyond the extent necessary for said
unlocking, to effect a change-over of the maga
zine entrances.
3. A typographical composing machine com 35
prising a lock for the magazine shifting mecha
nism, means adapted to release said lock upon
being operated to a limited extent, a plurality of
magazine entrances rotatable as a unit for bring
ing one or other into operative position in rela 40
tion to the magazines, and a linkage system, con—
meeting said magazine entrances to said releasing
means, adapted to rotate the magazine entrances
when said releasing means are operated beyond
said limited extent.
4. A typographical composing machine accord
ing to claim 3, comprising a lock for said maga—
zine entrance unit adapted to be released upon
operation of said means to the extent necessary
for releasing the magazine shifting mechanism. 50
5. A typographical composing machine having
adjustable magazines and interchangeable maga
zine entrances, wherein common means are em
in which the disc 4| has been released so that any
ployed for unlocking the magazine shifting mech
further movement will cause the locking pawl 45
and the disc 4|, together with the shaft 25 and
the toothed Wheel 29 mounted thereon, to turn.
After a quarter of a revolution, the stud 39, under
the action of the spring 38, drops into the nex
notch 49 of the disc 4|; the parts are then in the
position shown in Figure 4. The transmission
ratio between the toothed wheel 29 and the
toothed wheel 30 is such that one quarter of a
revolution of toothed wheel 29 causes toothed
Wheel 39 to make half a revolution and thereby
turn the support of the magazine entrance 180
degrees. In place of the magazine entrance 33,
which in Figures 2 and 3 is in the operative posi
