This invention relates in general to apparatus
for making multiple duplicate copies of type-,
written matter in typewriters, or the like, but
more particularly it has reference to improve
-> merits in an apparatus which provides multiple
duplicate copies of typewritten matter substan
tially as clear, and of the same quality, as that
of the typewriting as appears on the ?rst or
original copy produced by the type from the
10 usual typewriter ‘ribbon ‘on, substantially, any
@make typewriter.
An important object "of the invention contem
plates the provision of a parallel series of‘ mov
able inked typewriter ribbons interposed in par
allel relation with and between the usual ribbon
and platen of ‘a typewriter to eliminate the use
of sheets of carbon paper and, fonmaking a
number of duplicate copies substantially similar
to the ?rst copy as produced by the type from
the ?rst or usual typewriter ribbon.
A further and important object of the inven»
tion contemplates the provision of hinged ribbon
guide arms which are adapted to receive and
guide the ribbon directly from and to the ribbon '
spools in a straight line.
A further important object of the invention
contemplates the provision of an arrangement of
a series of movable typewriter ribbons arranged
to travel in unison longitudinally with the typewriter platen carriage and in the manner of the
platen during the period of operating the type
writer, or instantly after each type-bar stroke.
Another important object of the invention con
templates the provision of an arrangement‘ of
a series of automatically movable type-writer
ribbons arranged to travel in a vertical plane and
in parallel relation to the longitudinal faceof the
type-writer platen, and in unison therewith and
in a like manner thereof during the period of
operating the typewriter, or instantly after each
type-bar stroke.

the ribbon or ribbons, in taut parallel relation to
the face of the platen throughout its entire length 20
during the period of operating the typewriter.
The ribbon operating mechanism contemplates
the provision of a series ‘of ratchet driving
clutches which may be arranged to operate the
ribbon or ribbons, in reverse directions across the 25
longitudinal face of the platen. The operating
mechanism also contemplates the provision of
means by which the driving clutches may be ar
ranged in a neutral or inoperative position. _
It is further contemplated to provide in this 30.
invention means for engaging the ribbon operat
ing mechanism to prevent thesame from paying
off ribbon while backing up the 'work on the
platen, and, to prevent the ribbon, or ribbons,
from being drawn with and between the work 35
while the same is being reversed on the backing
up of the platen.‘
'
-' A further and important object of this in
vention is to provide parallel inclined hinged
ribbon guide arms so arranged and constructed 40
as to carry the ribbon in as direct a path as pose
sible to or from the ribbon takeup spools to its

mit the arms to clear the hubs and the heads 45
of set screws that may be in the hubs, of the
platen on any make typewriter in order that the
ribbon, or ribbons, may be guided from the take
up spools to the above stated position before the
platen in, as before stated, as direct a. path as 50
possible. There being further provided on the
arms, at their outward extremities, means to
guide the inclined portion of the ribbon around
a lateral or outstanding angular corner to a ver
tical horizontal position and parallel with the 55
2
aroaavo
