'
In-lieu of the usual carbon paper the present
invention contemplates the use of auxiliary rib
30 bons, one of the frames therefor being shown in
position in Fig. 1 at R.
Referring to Fig. 2 which shows the details of
the ribbon frame R, the frame may consist of a
unitary sheet metal stamping comprising a lon
35 gitudinal bar 20 extending nearly the length of
the platen, having downwardly extending arms or
legs 2| ‘at the opposite ends thereof, each equipped
lection of ribbon area exposed to impact. For this 15
purpose the support lug II, is provided with an
extension II therebeyond, affording a rest edge ll
therebelow preferably connected to the rest edge
22 by an inclined surface I2. Similarly the oppo
site support Ol which is near the outer extremity 20
of the frame, is equipped with an additional rest
ing edge N at lower level and adjacent arm 2|.
the two rest surfaces 23 and I4 being connected
by an oblique edge ‘I. Thus the frame affords in
addition to the rests l2 and 33 shown in operative
position in Fig. 2, additional rests II and I‘ at
lower level and to the left of the first rests. The
latter rests may be brought into operation by
simply shifting the frame as shown in Fig. 2 to
the dot and dash position in which the frame 30
would readily ride up along inclined edges l2 and
55 to bring rests II and 54 into operation, thereby
elevating the ribbon preferably through approxi
mately half the width thereof and shifting the
same to the right through a corresponding range. ' '
By a thrust to the left the ribbon holder ‘could as
readily be shifted from the upper to the lower
position shown in full lines in Fig. 2. In the shift

In either of the two positions shown in Fig. 2 it

thereof, and the metal above the notch 28 is bent is apparent that, the spring holders 36 are equally

which coacts therewith in either position of the
The frame supporting arm 2| has an oblique
edge 28 adapted to lodge in the sheath formed by
the turned over part 29 and has a latch 28' pro
56 truding through the notch 26 and thereby e?ect
ing the desired lock. The spring clip here dis
closed is, of course, of more general application to
ribbon holders of the type shown in my prior
patent.
The frame has lateral extensions 30 and II at
opposite ends thereof, affording supports 22 and
33 respectively to rest upon the side frames F,
with the bar R over the sheets and the ribbon
65 length 25 between two of the sheets, as best
shown in Fig. 1.
To retain the-frame in position with sufficient
security during typing, there are placed on each
of the side frames F of the carriage spring retain
70 ers best shown in Figs. 3 and 4. Each of these
retainers preferably comprises a blank 'of sheet
metal 36 extending longitudinally of the frame,
having lateral ?anges 31 overlapping the sides of
the frame and secured in position at one end by a
75 screw as which may be one of the screws that
holder will be at the same level.
By the present arrangement accordingly, after
a ribbon has become worn in one position of use
of the frame, the disposition at the other of the Q1 Gil
two alternative positions exposes to the type im
pact an entirely fresh area of ribbon at the lower
half of its width and at a different portion of its
length.
The present inventionalso admits of effective 60
use of two-color ribbons, the choice of color there
depending on the choice in the two alternative
mounts of the ribbon holder.
By the present arrangement it is immediately
apparent that two, three or more of the ribbon
holders could be used simultaneously to produce
a corresponding number of copies, the frames 20
of all of said ribbon holders extending in front
'of the platen and of the paper, the respective
ribbons extending between successive pairs of 70
sheets, and the spring ribbon frame retainers 36
all overlapping the entire series of ribbon holders.
In such arrangement it will be apparent that all
ribbon holders need not be used in the same
one of the two alternative positions but some 75
3
2,088,448
may be in upper and some in lower position, de
pending on the wear of the ribbon or the choice
of color type wanted for the respective copies.
As in the embodiment of the prior patent, the
ribbon will be of such length that when in posi
tion on the frame it will exert tension which the
resiliency of the frame will accommodate thus
to maintain the ribbon taut.
While the use of a metal frame is generally de
10 sirable, advantages are obtained by making the
frame of translucent or transparent composition
A such as celluloid, phenol product and the like.
The transparency of such composition affords the
distinct advantage of avoiding any obstruction
of vision at the cross bar 28.
In the embodiment of Fig. 6 a frame of the
general principle of that of Fig. 2 is shown, made
wholly of a unitary piece of wire, corresponding
reference numerals designating analogous parts
20 .in the embodiments of Fms. 2 and 5. The longi
tudinal run 20' is reversely bent at one end to
afford rests 33' inclined surface 55' and lower
rest 54’ adjacent arm 2|’. At the opposite end
the reversely bent wire affords rest 5|’ contigu
N) On ous to inclined surface 52' and rest 32' from
which extends the left arm 2|’.
The ribbon frame of Fig. 6 is of such negligible
width that it does not appreciably interfere with
visibility.
30
Since the ribbon mounting clip of Fig. 2 is
not adapted to the wire mounting arm, it is pre
ferred in this embodiment to use a clip such as
shown in Figs. 7 and 8.
The clip 68 is crimped as at 8| to the ribbon
length and has two integral protruding hooks 82
at opposite‘ edges thereof which become lodged
in corresponding notches 63 in the ribbon mount
ing arms of the frame.
In Figs. 9 and 10 is shown another embodi
40 ment of ribbon mount in which the end-of each
ribbon mounting arm 2la is flattened as at 84
and rivets 85, preferably two in number, a?lx the
ribbon end to the holder. In this embodiment
the ribbon is not removable in respect to the
- simple wire holder frame, the unit being so sim
ple and inexpensive that it is intended to be dis
carded in its entirety after the ribbon is spent.
If desired, a form of ribbon could be used which
admits of re-inking to regenerate the unit.
In Fig. 11 the ribbon is shown with a, unitary
loop 10 stitched to the main length of the ribbon
12 as at ‘H. The loop is to be telescoped over
the arm 2| b of the ribbon frame, which arm if
desired may be provided with a notch 13 at its
lower end to accommodate the width of the rib
bon, which again is of such length as to exert
strain upon the frame.
In Figs. 12 and i3 is shown an alternative em
bodiment in which the ribbon frame has a lon
60 gitudinal arm 88, ?nger tab 8| and ribbon carry
ing arms 82 with latching means 83 generally
similar to those of the other embodiments, ex
cept for the fact that the ribbon carrying armsv
in this case are curved for adaptation to the
65 platen as shown.
Integral with the frame and extending rear
ward from opposite ends thereof are spring arms
85 curved ‘away from the platen and preferably
provided with an indented portion or hump 88
to straddle the bar 81 or equivalent instrumen
tality which constitutes part of the standard
construction of a typewriting machine. The free
‘end of each of the arms 85 extends in direction
generally tangential of the platen and preferably
has a loop 88 at its free end to engage the
platen P.
’
Preferably the arms 85 are of such length and
con?guration that as the arm 82 is brought cor~
rectly to rest against the platen, looped end 88
is resiliently forced past the maximum bulge of
the platen and loosely engages the platen in
home position as shown.
Preferably the indentation 88 is somewhat
wider than the bar to afford some freedom of
back and forth movement for slight automatic
shift of the ribbon ‘during typing‘which move
ment is permitted due to the loose engagement
of arm 85 with the platen as just set forth. The
frame 80 is somewhat shorter than the distance
between the side frames of the machine, thereby
to permit freedom of displacement of the ribbon
frame.
In the preferred embodiment, in addition to
the hump 86, one or more further humps at 89 -
are provided. By this means there is afforded
the possibility of setting the frame in two or more
alternative positions relative to the platen to ex
pose to type impact at will, either of two or more
different regions of the ribbon width.
25
In this embodiment it will be seen that the
ribbon frame is applied in position by a single
thrust to retain the frame in coordinated rela
tionin respect to the typewriter platen and yet
to permit slight automatic shifting thereof dur
ing action, thereby to lengthen the life of the
ribbon by exposing to type impact ever chang
ing regions of the ribbon. The bar 81 retains
the ribbon frame however in such position as to
permit ready rotation of the platen as desired
without disturbance of the ribbon frame.
In the embodiment of Figs. 14 and 15 is shown
a conventional typewriting machine similar to
that of Fig. 1, the side frames 98 each having
the usual cover plate 9| which at its inner edge
92 protrudes beyond the carrying structure in
the customary manner.
The ribbon frame 93 is similar in general con
struction to that of Fig. 2 or of Fig. 12, the rib
bon arms 94 thereof being either straight or 45
curved to accommodate the platen as desired and
having the oblique conformation 95 for mount
ing of the ribbon clip (not shown). Integral with
the outer edges of the arms 94 are resilient mount
ing arms- 96 protruding forward and upward 50
therefrom with the free end 91 thereof to ex
tend above the side frames. These resilient arms
are corrugated as at 98 to resiliently engage ‘and
overlap the free edges 92 of the cover plates for
resilient mount of the ribbon frame as a body be
tween the two side frames, for coaction with the
platen. Preferably the upper edges of the corru
gations 98 are oblique, as shown at 99, and the
space between the successive corrugations is con
siderably wider than the thickness of the cover 60
plate 9|. Accordingly, the frame can yieldingly
shift to the left or to the right slightly within
the resilient limitations of the arm and can shift
upward and downward through a range limited
by the width of the corrugations 98, thereby to
vary the impact area of the ribbon. By affording
two or more of the corrugations on each arm 96,
as shown, choice of selection in the width of rib
bon exposed to impact is afforded, as is readily
70
understood.
While the ribbon frame is shown constructed
and arranged to afford both limited longitudinal
movement and limited peripheral movement, it
will be understood that the constructional fea
tures as described and claimed may be used’ to 75

advantage for either longitudinal movement alone
or peripheral movement alone, and the frame
.may be disposed even in relation immovable to
the typewriter frame during use.
'
It will thus be seen that vthere is herein de
scribed apparatus in which the several features
of this invention are embodied, and which ap
paratus in its action attains the various objects
of the invention and is well ‘suited to meet the re
10 quirements of practical use.
