working through the adjusted spacing means,
moves the driving connection and connected type
writer carriage in desired amounts.
Both the operating connection to the key bars
and the driving connection to the typewriter
plate 44. The plate is closely held except for
free sliding movement in the direction of the
slots.
I
The justi?er carriage 45 is supported upon the
frame portion l5 for reciprocating movement in
the direction of rack travel.
As shown, the car
carriage are of such character that they are
readily made upon assembly of a typewriting ma
riage 45 has horizontally extending V rails adja
chine to the frame. The operating connection is
cated at 50 and 5|. The frame i5 has V rails 50'
and 5|’ facing oppositely to the carriage rails and 10
spaced therefrom an amount sufiicient to receive
10 arranged as a rockable ball 20 which lies within
the horizontal frame portion ii and extends
across it beneath the typewriter key bars which
are indicated generally by the numeral 2i. As
shown, the rockable bail 20 comprises parallel
15 side rails 22 which extend upwardly at their for
ward ends and are joined to a cross rail 23 which,
in the normal position of the rocking member,
' lies directly beneath the key bars and is of sum
cient length transversely of the typewriting ma
20 chine to underlie all of the keys, which have to
do with a spacing movement, that is, all of the
spacing or character keys. The ball 20 is sup
ported on a pivot shaft 24 carried by the frame
II and extending through aligned openings 25 in
the side rails 22. Toward the rear of the machine
the side rails are bent inwardly toward one an
other and are together bent to the rear to form
a rearwardly projecting arm 25 'to which a link
I‘! is pivotally attached by engagement in an
opening 25 formed adjacent the end of the arm
26. A spring I0 serves to urge the rockable bail
upwardly toward its normal position.
The cross rail ll lies closely adjacent the key
bars so that upon actuation of any one of the
35 named keys the bail '20 is engaged thereby and
is caused to rock and thus impart an upward
movement to the link 2‘! which has an operating
connection to an escapement mechanism on the
justifying device. The escapement, which may
be of any suitable character, is shown to be of
that type which is well known in the art and com
prises a star wheel to which step-by-st'ep move
ment is imparted by movement of a rock member.
In the present instance the rock member is actu
45 ated by movement of the ball 20. As shown, the
link 21 is adjustably connected to a vertically
slidable block 33 having an inclined forward face
34 that is engaged by the lower portion of the
Spring Dressed rock member 35 that serves as the
escapement release and controls movement of
the escapement star wheel 36. Reciprocating
movement of the link 21 rocks the member 35 to
release the escapement wheel 35 for movement
by the amount of one space step. A pinion 38
cent the upper and lower edges thereof as indi- “
bearing balls therebetween. A plurality of balls
52 are positioned between the rails‘ of each 'of the
rail pairs and are maintained in properly spaced
relationship by the provision of suitable spacing
means. The bearing balls are spaced by being
loosely mounted within star wheels 53 turning
on vertical axes of which the teeth engage the
teeth of ‘racks positioned on the opposite sides'of
each of the related rail pairs. The racks extend 20
vertically, are laterally spaced and are positioned
so that the teeth overlap in the plane of travel of
the star wheels 53. As shown, the rearward sides
of the carriage rails 50 and 5! have racks 54 while
the forward sides of the frame rails 50' and 5!’ 25
have racks 54’ attached thereto as indicated in
Fig. 1. The proportioning of the pitch diameter
of the- star wheels, the diameter of the bearing
balls and the arrangement of the rail grooves are
such that free rolling movement is afforded while 30
preventing the bearing balls from moving from
their properly related positions.
It is the controlled relative movement between
the rack supporting plate 44 and the justi?er car
rlage 45 that affords the space change necessary
in the stepped movement of the typewriter car
riage to provide justified writing, and mecha
nism is interposed between the plate and carriage

trolled movement may obtain‘. In order that the 40

escapement they are spring tensioned so that
they are constantly urged toward the left (as
viewed in Fig. 3) which is toward the right hand 45

spool 56, well known in the typewriter art for
this purpose, carries a tape 51 that connects at
58 to the carriage 45 to provide the desired ten

will now be apparent that vertical displacement
of the frame 9i controls the amount of total justi
40 fication produced in a line, and that this amount
of justi?cation is nota function of the line length.
That is, a line three inches long and three char
acter spaces short of justified line length will re
quire the same amount of justification as a line
45 eight inches long that is three characters short.
As shown, the segment has sufficient notches to
justify lines as many as six characters short of
justified length. ‘Practice has proven that this
is a su?lcient range of adjustment. It is be

The amount of justification per character space

is not limited to this precise form of apparatus,
and that changes may be made therein without
departing from the scope of the invention which
is defined in the appended claims.
What is claimed is:
.
1. A justifying device operable to different
justified line lengths and comprising a movable
‘platen, means for moving the platen by character
space steps, adjustably variable means for vary
ing the length of a character space step and
pivotally movable on a fixed mounting to a de
sired one of a plurality of positions having co
ordinated relationship to the unjustified line
shortage and to the justified line length, po
sitioning means .engaging the variable spacing
means and movable in a rectilinear path of travel
for the line shortage adjustment and in a trans
verse rectilinear path for the line length adjust
ment. and means for selectively attaching the 20
platen to the platen moving means at a desired
one of a plurality of positions spaced in. the di
rection of platen movement.

2. A justifying device operable to different line

It is pointed out that a-typewriter when as~ able in a plane and on a ?xed axis for varying

the length of a character space step and mov
30 out the justifying mechanism as desired. When
able to a desired one of a plurality of positions 30
used with the justifying mechanism the type
writer escapement is rendered inoperative ‘so that
the typewriter carriage movement is under con
trol of the justifying mechanism of the jus
35 ti?er unit and is actuated in accordance with
the operation of the justiiier escapement and ad
Justed setting. When so used the typewriter es
capement may be readily rendered inoperative
by merely providing a latch that will hold the
40 typewriter escapement rack bar in disengaged
podtion. When the typewriter is to be used in
the normal manner it may be so operated through
the justifying mechanism with the adjustments
set to a position of no justification (with the ad
45 lusting member ill in horizontal position) or it
may be operated from its own escapement upon
rendering the driving connection to the justifier
inoperative. This is accomplished by disengag
ing the latch 03 from the typewriter carriage to
50 the justifier carriage. No change is required in
the operating connection because in no instance.
is there a positive drive connection between the
typewriter and the justifier; it having been point~
ed out above that the operating connection exists‘

underlies the keys and stands‘ closely adjacent

is such that an existing typewriter may be read

to the standard typewriter and that when so as

desired one of a plurality of positions having co~
ordinated relationship to the unjustified line
