19 Claims. (Cl. 197-126)
This invention pertains to manifolding appa
ratus and comprises carbon shifting means for
. repetitiously employing short-lengths of carbon
or transfer material with multiform continuous
series connected stationery.
0
Heretofore it has been quite common practice
to interleave continuous strips of multiple forms
with like strips of “one-time” carbon or transfer
material, which after being once used is dis
10 carded. Although effecting a saving of time such
method is expensive and necessitates ‘a great
waste of material. Numerous forms of carbon
shifting apparatus have been devised, wherein the
interleaved transfer material must be manually
manipulated and adjusted after each writing op
eration, or wherein either the transfer material or
the record material must be clamped or otherwise
held stationary while the other material is manu
v
ally adjusted relative thereto.
Although affording satisfactory results such
carbon shifters have been found quite expensive
to manufacture, difdoult to use, necessitating con
siderable loss of time and requiring skill and
- extensive manual effort by the operator.
The present invention provides an inexpensive
method and apparatus which overcomes the dim
culties of former carbon shifter mechanisms by
employing interleaved transfer sheets which are
advanced past the writing position in unison with
0 advancement of associated strips of record ma
, terial, and upon completion of the writing opera—
tion their advancement is automatically arrested
while the inscribed portions of the record strips
are further advanced independently of and rela
tive to the transfer to a tear-off position where
the inscribed portions are detached from the sup
ply strips.
_
a
- - During‘ the unison advance movement of the
manifolding assembly an automatic retractive de
vice is tensioned or energized to effect a subse
quent movement of the record material and asso
ciated transfer material into position for succeed—
ing writing operations. The relative advance of
the record strip independently of the transfer ma
terial at the completion of the writing operation,
positions the succeeding set of forms or record
‘sheets to be inscribed in registry with the trans
fer sheet, after which the entire assembly of
‘ transfer sheet and advanced record strips are re
50
ing means.
_
After the forms or record sheets
terleaved transfer sheets have‘ been
sitioned relative to each other, with
amount of care on the part of the
advancing the strips to the tear-off

and the in

a reasonable
operation in
position, in- 10
dependently of the transfer sheets, the registry
of the transfer sheets with succeeding sets of
forms will be automatically maintained.
The object of the invention is to simplify the
construction as well as the means and mode of
operation of carbon shifting devices of a mani
folding apparatus whereby they may not only be
economically manufactured but will be more e?i
cient in use, automatic in operation, uniform in
action, of increased accuracy, having relatively 20
few parts, and unlikely to get out of repair.
A further object of the invention is to provide
feeding means for uniformly advancing the trans
fer and record material an initial distance in uni
son and then automatically arresting the trans- 25
fer material while the record material is differ
entially advanced relative to the transfer mate
rial through an additional distance.
A further object of the invention is to provide
means for automatically re-engaging the transfer 30
material with the feeding means for retraction in
unison with the record material.
1
Another object of the invention is to provide
means to automatically retract the transfer and ,
record material in unison after the record mate- 35
rial has been advanced relative to the transfer ;
material to tear-off position and a succeeding set
of forms to be inscribed has been registered with
the transfer material.
A further object of the invention is to provide 40 1
an adjustable platen capable of lateral movement
to enable the record material to be shifted rela
tive to the type impacting position of the imprint-1
ing machine to insure columnar registration.
With the above primary and other incidental 45
objects in view as will more fully appear in the
speci?cation the/invention consists of the fea
tures of construction and the parts and combina
tions thereof and the modeof operation or their
tracted in unison to the initial writing position ' equivalents as hereinafter described and set forth 5°
preparatory to the succeeding writing operation.
The automatic retractive means may be e?ec
tive only to re-engage the transfer material with
the feeding means preparatory to reverse feeding

Brie?y stated the present carbon shifter at
tachment comprises a frame extending upward
ly and rearwardly from the platen or the writ
ing position of the recording or imprinting ma
chine over which superposed strips of record ma
terial and interposed transfer material sheets are
progressively advanced beyond the writing posi
40 tion.
Associated with‘ such frame is a pin type
feeding device, the pins of which are progressive
ly engageablein longitudinally spaced holes in
, the record material for positively" advancing the
record material and with it the associated trans
45 fer sheet past the writing position.
.
Carried by such upwardly and rearwardly ex
tending frame are parallel endless beltsx having
therein successions 'of spaced feed holes registrable with those of the record material in which
the pin type feeding. device is engageable simul-'
taneously with its engagement in the marginally
_ punched holes‘ of the recordstrip. These endless
traveling belts which pass about the platen roll
at their lower ends and about idler pin wheels
at the upper limit of the supporting frame are
intergonnected by a carrier bar to whichv the
er sheets are attached in interleaved rela-_
tion between the record strips. The platen roll
- trans
and endless traveling belt engaged by feeding‘
pins associated with the platen roll are advanced
through step by step movement by the customary
‘ line space mechanism. The feeding pins carried
by the platen roll extend through the holes in the
“traveling belt into simultaneous engagement in
marginally punched holes in the record strip and
cause the record and transfer material to be ad
vanced in unison ' past the writing position.

Extending upwardly and rearwardly from the
platen roll I! is ‘a frame including jointed ex
tensible side bars, the lower portions 40 of which
are mounted upon the platen roll shaft 42. The 40
upper extensions“ of the side bars are adjust
ably connected with the portions 40 by’a clamp
bolt 48 engaging inyslots 50 vwhich enable'the
frame to be extended or retracted within the
limits of such slots. Journaled in the upper ends 45
of the frame bar extensions 46 is a countershaft
62 carrying spaced pin wheels 64 having radial
pins or studs 56. ,Mounted upon the extremity
of the shaft 50 beyond the sideframe member
is a revoluble spring housing 60 provided with a 50
peripherally notched ?ange "within a notch '14
of which a detent 62 upon the frame bar 46 en
gages to hold the housing in its adjusted position
of rotation.

Enclosed within the housing 60 is an involute 55
spring "one end of which is engaged. with a
stud or tongue 64 upon the interior of the housing '
60 and the opposite end 66 of which is engaged in
a slot 68 in the end of the shaft 52. The con- >
struction' is such that as the housing is held sta
60'
tionary relative to the frame, the rotation of
the shaft 52 by the advancement of the perfo
rated endless belts 32 serves to wind the spring
58 placing it under su?lcient tension, whereby its
subsequent reaction, when permitted to do so, 65
will drive the shaft 52 and pin wheel 54 carried

sheets are attached to transverse carrier bars 28
the terminals 30 of which are connected by rivets
38 to the parallel endless belts 32 for unison
travel therewith.
In the normal operation of making manifold
copies the initial forms of the record strips and
interleaved transfer sheets are progressively ad
vanced past the writing position through a step
by step movement incident to operation of the
customary line spacing mechanism, by the en
gagement of the feeding pins it carried by the
platen roll l2 in the spaced holes of the endless
belt 32 and simultaneously in the corresponding
spaced marginal holes of the record strips. Such
40 positive step by step advancement of the mani
folding assembly continues until the end of the
form to be'inscribed is reached at which time
the perforated endless belt will have been ad
vanced sui?ciently to bring the slots 85 thereof
45 into the pin engaging position. The pins lél
entering the slots 80 of the belts will rotate idly
30
therein while still maintaining their feeding en
gagement with the marginally punched holes of
the record strips. By the continued rotation of
step by step advancement of the, manifolding as
sembly and the belts 32 by the conventional line
spacing mechanism, the shaft 52 and pinwheels
56 are held against reverse movement under re
active influence of the tensioned spring 58, by
the pawl and ratchet 51 and 55. When the limit
of independent advancement of the manifolding
30
material has been reached and the inscribed por-,
tions of the strips have vbeen detached, the man
ual disengagement of the pawl 5'! by depression
of the arm 59 releases the spring for reactive
driving action upon the belts 32 by which the
platen roll is rotated automatically in reverse
direction to thereby automatically retract the
record and transfer material into writing posi
tion.
‘
At the limit of such retrograde movement the 40
carrier bars 28 for the transfer sheets engage a
suitable stop 35 adjustably mounted upon the
supporting frame, which arrests the belts 32 and
with them the platen roll and manifolding assem- _'
bly with the initial writing line of the record
material in the writing position, preparatory to
repetition of the writing operation and subse
quent advancement of the manifolding assembly
by which the spring is again tensioned.
