For purposes of ready description a preferred
embodiment of the invention is disclosed in the
justified linea-that is to say, in lines having a '
common length so that both margins arev aligned.
This is accomplished' by varying the length of the
character spaces in accordance with the number
of characters in the line. 'I'he length of space
is varied with respect to what might be termed
a normal space length. The adjusted space
length for any line is established by reference to> 55

a proper space length relationship may be estab

In the form of type character spacing device
illustrated the carriage I2 is supported for move
ment upon the frame I I. As shown, one side of
the frame II is provided with a guideway 20 hav
ing a groove 2| that is cooperatively related to a
similar groove in the guideway 22 on the carriage
I2. A plurality of bearing balls 23 are positioned
between the guideway grooves and provide a free
moving support at one side of the carriage I2.
Additional support is afforded by a rod 25‘that is

The justifier provides the operating connection
between that part of a type character associat
ing device from which the type characters are
associated, and that part which is relatively mov

In the drawings, in which like characters of
30
reference designate like parts throughout the
several views thereof, the numeral I0 designates
the type character spacing device or justifier
which is shown as having a frame portion Il and
35 a carriage I2 which is movable thereon. The
justifier as herein shown is mounted upon a
common base I3 with a typewriter I4 although
it is to be understood that the justifier need not
be a separate part from the typewriter or other
40 character associating device. 'I'he typewriter
comprises generally a frame I5 and a carriage I6
that is movable thereon. The justifier is oper
atively connected to the typewriter for controlling
the movement of the typewriter carriage I6
45 whereby the type characters associated or im
printed in word or other sequence relationship
on the platen I1 of the typewriter carriage IE
may be spaced to produce lines of common length,
that is to say, so that the lines may be justified.

as is common and well known for the movement
of a. typewriter carriage. As shown', a stud 30
(Fig. 5) on the frame -I I carries a rotatable spool
3I upon which a ribbon 32 is wrapped. One end 35
of the ribbon is fixed to the'spool and the other
end is connected at 33 to the carriage. A suit
able spring is attached to the stud 30 and spool
3| to tension the spool for movement of the
carriage to the left.
The escapement which controls the space by
space movement of the carriage I2, and which is
shown at 35, (Figs. 5 and 8) may be of any suit
able type such, for example, as that illustrated
which is well known for controlling the move- ..
ment of a typewriter carriage. As shown, the
escapement is mounted upon a bracket 36 which
is attached to the frame II and comprises a
rocking member 31 pivotally mounted upon the
frame 36 by means of pivot members 38. The 50

the relatively movable justifier parts II and I2
so that the space length of a character movement
may be varied in accordance with the number of
characters that are to be associated in a justified
70 line. For any given justified line the character
spaces are of uniform length, and in the differ

and, as a result of the spring tension on the
carriage I2, is held by the tooth against the
adjustable stop 44. Upon pivotally moving the

upon. the carriage. As shown, the carriage is
provided with spaced blocks Bi and SS. These
blocks are notched on their underside to receive
the racks as indicated at t9 and position the
racks in alignment with the corresponding gears.
Each rack is slotted as indicated at 5l corre~
sponding to the spacing of the blocks, and each
45 is held for sliding movement within the blocks
through provision of pins 58 that pass through
the rack slots 5i (Fig. 7).
The racks are selectively engaged with the car

As shown, the cams are
formed generally circular and each has an in

movement whereby a notch lî'may engage its «
associated pin 19. lThe cams are íixed to the
shaft 81 so that the cam notches are equally
spaced in angular relationship, and so that only
one arm may .move to engaging position at a
time. The selecting movement of the cam shaft 35
is through provision of al readily accessible

To produce associated type characters in lines
of justified length the characters are first asso
ciated in lines of random length by using normal
spacing.
This copy is then used as an index or
guide for reproducing vthe characters in lines of
justified length. To use >the illustrated struc

to be reproduced in justiiied lines` is first typed
on the typewriter in the normal manner to pro

in Fig. 10. The unjustified copy is produced
within the limits of a predetermined line length
as indicated by the vertical guide lines |20 and

~
The device is prepared to produce justified
lines by moving the carriage to the right hand
position and by turning the selector knob 9I so 45
that the pointer stands in the position of the
predetermined line length. This corresponds to
the cam positioning in which gear 50 and rack
60 are cooperatively connected to the carriage I2.
The unjustified copy is then placed in the carrier 50
so that the right hand margin of the predeter- .
mined line lengthl stands in registration with the
pointer. This is readily accomplished by pro
viding the unjustified copy with guide lines or by
placing a reference mark on the copy in the po
55
sition of the right hand margin. Having placed
the copy in the carrier as described the selector
knob 9| is then turned to move the pointer 99 into
registration with the last letter of the line that
is to- be recopied in justified form. This selects
the proper gear and rack that will produce vchar
acter spacing of the justifier such that the num
ber ‘of 'characters in the selected line will be ad- '
justed 'to produce a like number of character
spaces to'justiñed length.

35 tioning so that when the carriage is in the ex
treme right hand position the arm end |35 may
drop down an amount suflicient to release the de
tent |3|. In this position the arm vend |35 oper
ates against the end of the bar I3! as a positive
stop whereby the carriage may not be moved un
til the arm |28 is rocked by depressing the handle
portion |36 to engage the detent |3| and release
the arm end |35. Upon making the proper gear
selection- the handle portion 636 is depressed
whereupon the carriage moves to the left an
amount just sufficient to cause the arm end |35
to override the bar |36. The selected line is then
_typed in, justified form and the carriage is re
turned for selection of character space length for
the'next succeeding line.
As mentioned above, the justifier drive `connec
tion incorporating the gear 5|! and rack 60 pref
erably provides a normal character space length,
' that is, a space length corresponding to the _nor
55 mal character spacing of the typewriter., The
„ original unjustified copy may therefore be typed
on the platen of the typewriter carriage I6 either
by using the typewriter escapement or the justi
fier escapement as desired.
The justifier may be arranged to Vjustify any
60
desired line length by a proper selection of gears
constituting the drive connection. That is, hav
ing determined the justified line length, gears are
ment on devices which will not permita- compact
mounting such as is illustrated in those figures of
the drawings showing the justifier as a closely
positioned typewriter attachment the justiner
may be mounted in any vdesired position remote 30
from. the device upon Which-type characters are
associated by provision oi’an- operating connec
tion such as is shown in Fig. 9 wherein the car
riage of the justifier and the carriage upon ,which
the type characters are associated are intercon
nected by means of a shaft.. As shown,fthe justi
fier carriage I2' has attached to it a rackl|4ll
which extends parallel to-the direction of travel -
of the carriage. A gear |4| which is fixed to
a shaft |42 meshes with ther` rack |40. The 40
shaft |42 is supported in suitable brackets on the
justiñer frame and on a fixed portion of the
device upon which the type characters are
associated; The shaft-end adjacent the type
writer, or whatever device is to be controlledy 45
by the justiñer, carries a gear |43 4that is in
meshing engagement with a rack |44 that is
mounted upon a carriage portion |45 of the type
character associating device. 'I'he shaft |42 may
be of any desired length, and the operating link
age which operates the justifier escapement is
proportioned accordingly. Also `the justifying
mechanism may be built right into the type
writer in place of the. regular escapement. And,
of course, the same mechanism is effective for 55
producing such predetermined spacing in suc
cessive lines of type characterscf varying se
quence and arrangement as will give a predeter- ‘
mined length for successive or succeeding lines.
And, obviously, when desired-the variable spac 60
ing mechanism may. be made applicable to de
vices other than the typewriter in which the type
or impressing characters are effective within a
