15 Claims. (Cl. 197-126)
This invention relates to improvements in ?at
bed typewriting machines.
An object of this invention is to provide means
on such a machine for automatically shifting or
5 moving the transfer or carbon duplicating paper,
relative to the form sheets. In the art, as at
present practiced, it is customary to use rolls of
carbon or transfer paper which are manually
moved across the writing plate between the. form
if) sheets to provide fresh transfer'paper, when that
in use has become worn out.
objections‘ are entirely eliminated in the action
of this invention.
Another object of this invention is to provide,
in a ?atbed typewriting machine, apparatus
adapted to produce better, more uniform, and
clearly legible sets of form copies with a rela
tively lighter, more economical grade of transfer
paper than is at present customarily used‘in the
art. In the practice of repeatedly usingv the

same area of transfer sheets for a plurality of 10

practice are unsatisfactory. As the transfer
paper is repeatedly used in the same position
relative to the form sheets, the form copies be
lS come progressively less legible, from a clear set
of copies for the ?rst set of forms to a set so
nearly unreadable as to compel a change of trans
fer sheets.
expensive grade of transfer paper, capable of
withstanding repeated use for a reasonable length
of time. If the cheaper grades are used, too
much; time is wasted in changing the transfer 15
'
It is an object of this invention to provide
99 means for automatically and progressively shift
in'g, in a step-by-step manner, the transfer sheets,
relative to the form sheets, as the sets of form
sheets are completed and renewed.
A result of the use of this invention is to- pro
37, vide absolutely uniform sets of form copies. As
the transfer paper is shifted. for each' set of
forms, a new surface is presented to the typefor
each set of forms, therefore, all the sets of form
copies will be uniform and equally legible, par

A further object of this invention is‘ to provide,
in a flatbed typewriting machine, means for auto
matically subjecting‘both form sheets and trans
fer sheets to a tensional strain, when inoperative
7, position on the writing plate, thereby drawing
them taut and insuring proper alignment and
registration of the form sheets. The result of
this action also provides’a flat, compact arrange
ment of form sheets and transfer sheets on the
.313 Writing plate, without air cushions between the
layers. This‘ result is impossible with mecha
nisms now in use.
When rolls of carbon are used,
it is. impossible to draw the several layers of
carbon paper taut, as the outside layer of carbon
paper, as it leaves the roll, is circumferentially
.5 Li
longer than the next adjacent layer. The result
of this condition is‘to provide, in the set‘of forms
and transfer sheets on the writing plate, a pro
gressive degree of looseness in the transfer sheets
50 fromthe bottom layer upward. This condition
provides air cushions between the layers, result
ing in poor copies. It also presents a “soft” re
sistance to the‘ type which often causes piercing
H
and'tearing of ‘ the original form sheet'and the
55 layers immediately beneath, bythe-type. These
paper.
'
These, and other‘ objects and advantages of
our invention, will be more completely disclosed
and described in the following specification, the
accompanying drawings, and the-appended claims. 20
Broadly, our invention comprises,’ in combina~'
tion with a flatbed typewriting machine, a mech
anism for drawing a plurality‘ of ‘sheets of‘ trans
fer paper across the writing‘ plate; a mechanism
for producing and releasing a‘tensional strain‘ on 25
the transfer paper; a mechanism for producing
and releasing a‘ tensional strain on the form
sheets, and means co-operating with the‘ usual
form-gripping apparatus of the flatbed typewrit
ing‘machine for‘ operating these mechanisms.
30
For purposes- of clear illustration of the in
vention, the typewriting apparatus has been
omitted from the drawings, as being old in the
art and formingno part of the invention, ‘except
in co-operation in its usual functions.
A‘ preferred embodiment of our invention is
illustrated‘ in the accompanying drawings‘, in

the pedal I2 is released, the soft rolls I8 move
downwardly and, by engaging the forms ‘I be
tween themselves and the hard rolls I'I, pull or
draw the forms backwardly in opposition to the
holding force of the hooks 6, thereby inducing
a tensional strain in the forms ‘I between the
co~operating rolls I1 and I8 and the hooks 6,
which tends to tauten the forms 'I, thus holding
them ?at on the writing plate 2 and maintaining
them in proper alignment and registration, for

Referring now to the drawings in detaiL-in of the shaft I 4, engage bevel gears 28 and 29,
respectively. The bevel gear 28 is secured on a.
15 which like numerals refer to like parts through
shaft 35, which is revolvably supported in brack
out:—
A ?atbed typewriting table, or frame I, having ets 3i secured on- the lefthand track member 3,
as shown in Figs. 1 and 4. Arm members 32, ?xed
a writing plate, bed or table 2, and track mem
bers 3 and 4 for movably supporting, above the on the shaft 3!] for guiding the transfer paper
20 bed 2, a typewriting machine, (not shown), is
35, support, between their outer extremities, a:
guide rod 33 for the paper. A tension rod 34,
provided with a form. sheet securing 1 plate 5,
adjacent the shaft 38, is secured on and between
having a plurality of hook members 6 for engag
ing registering openings 8 in the form sheets ‘I the curved arms 35 which are pivotally supported
by projecting through the registering openings in at 36 on the arm members 32. Tension springs
25 the form sheets 7!. A clamping bar 9 is provided
with openings I8 which register with the hook
members 5, thereby permitting the bar 9 to clamp
the form sheets 'I tightly against the plate 5,
with the hook members 6 projecting into the
30 openings II). In the art, as at present practiced,
a clamping bar is used, but is not provided with
openings corresponding to the openings I8. Im
pingement of the clamping bar on the hook mem
bers 6 - prevents the clamping bar from forcing
35 the form sheets tightly against the plate 5.
The
clamping bar 5 is secured in the usual manner
tov actuating mechanism, (not shown), for rais
ing and lowering the same. This clamping bar
actuating mechanism is the same ordinarily em~
40 ployed on such machines, and is operated by a
foot pedal I2, pivotally secured in a bracket I3,
mounted on the frame I. (See Fig. 2).
An operating ordriving shaft I4, revolvably
supported in the track bar members 3 and A, is
as or operatively connected for oscillating, or rocking
movements, to the pedal i 2 by a crank arm I5
and connecting rod I 5. The form sheets ‘I are
normally gripped between hard rollers I‘! on the
shaft I 4 and soft rollers I8, of suitable material
such as live rubber, secured on a shaft I9, which
is revolvably supported in link, or arm members
20. The arm members 26 are pivotally secured
on bars, or links 2I, which are adjustably se
55
cured on the track members 3 and 4, as shown
in Figs. 2 and -3.
Guide rollers 22, revolvably
supported on a shaft 23, secured in the tracks
3 and 1-2, are adjustably spaced for varying widths
of form sheets by means of collars 24.
In operation, when the foot pedal I2 is de
60 pressed to raise the form-clamping bar 9 to re
lease the form sheets 1, lifting arms 25 secured
on the shaft Ill, engage} the shaft I9 and raise
or elevate the soft rolls I8, as indicated in Fig. 3,
thereby releasing'the form sheets ‘I from engage
65 ment between the rolls I‘! and I8. The prepared
forms on the writing plate may then be released
from the hooks or pins 5 and pulled forwardly
across the writing plate by the operator, until
the next set of form sheets is in position. This
70 next set of forms is then engaged on the hooks
5, the pedal I2 is released to bring the form
clamping bar 9downward onto the forms ‘I , and
the previously prepared forms, which have been
pulled through,‘ until free of the clamping bar 9,
37, secured at one end on the members 32 and at
the other end, to the curved arms 35, normally '
retain the tension rod 31% in close association with
the guide rod 33.
'
Edges 38, of the sheets 39 of transfer paper,
are guided between opposed faces 48 of the arm
members 32 and opposed curved arms 35.
transfer sheets 39 are zig~zag folded to form a
pack M, which is enclosed in a magazine 42 pro
vided with a slot 53, through which the transfer
sheets may be drawn, as indicated in Fig. 4. The
magazine 42 may be removably secured on a bar F."
M on the frame I, by means of clips 455, or, if
desirable, may be laid on the ?oor or on a shelf
adjacent the frame I. The pivotal mounting of
the curved arms 35, co-operating with the springs
3?, permits the tension rod 34 to automatically 40
adjust itself to variable tension on the transfer
sheets 39, relative to the rod 33.
The bevel gear 29 is secured on a shaft 46,
which is revolvably supported in brackets 47, se
cured on the righthand track member 4. A gear »1.

48, revolvably, or loosely supported on the shaft
46, between. a collar 49 and a ratchet gear 55},
meshes with a gear 5I ?xedly secured on a second
shaft 52, as indicated in Fig. 9. A pawl 53,
mounted on the loose gear 48, is normally held .i-i;
in engagement with the ratchet gear 58 by a
spring 54, so that when the shaft 46 is revolved
in an anti-clockwise direction, as indicated by
an arrow 55 in Fig. 9, the loose gear 48 will be
revolved with theshaft 45 and cause the gear 5i
to revolve in a ‘clockwise direction, as indicated
by an arrow 55, but when the shaft 55 is revolved
in a clockwise direction, the gears ‘t8 and 55 will
remain stationary. A gear 51, ?xedly secured on
the shaft 52, is normally in engaged relation with 21*:
a gear 58, secured on a shaft 59.
The shaft 59
is revolvably supported in link members 68 which
are pivotally secured on arms 6| and the shaft 59,
when in operative position, is supported in bear~
ing slots, or recesses 52, provided in the arms 6|.
(See Fig. 8.) In operation, when the shaft 52
'
and gear 57 are revolved in a clockwise direction,
the transfer sheets 39 are drawn between the
meshing gears 57! and 58, and are thus pulled,
or drawn across the plate 2. Thearms 68 are 70
adjustably secured on the brackets 4'! by means
of engagement of screws 63 in slots 84, and the
degree of engagement, or mesh of the

sheets relative to the manifold forms in a step
by-step manner, and means operated by the mov
ing means for automatically imparting a tension
effect to the transfer sheet when the moving
sheets 39, by movement of the arms 6 l , thus vary~
ing the distance between the shafts 52 and 59.
When it may be desirable to free the transfer
sheets 39 from engagement between the gears 51
and 58, or to install a new set of transfer sheets,
the shaft 59 may be thrown back out of the
slots 62 in the arms (if, as indicated in Fig. 8.
Rollers 65, mounted on the shaft 52, assist in
guiding and maintaining alignment of the trans

2. In a manifold printing apparatus, a clamp
ing device for securing one of the ends of the
manifold forms having openings therein, a pedal
10 fer sheets 39.
(see Figs. 1 and 12), ?xedly secured on the shaft
52, is engaged by a latch 61, fastened on the
frame I, to prevent anti-clockwise revolution of
the shaft 52, and serves, in co-operation with the
gears 51 and 58, to ?rmly hold the transfer sheets
39 in opposition to the opposite pull of the rods
33 and 34 on the opposite side of the machine
during their return movement, from the ele
vated position, indicated in Fig. 5, to the lowered
20 position, indicated in Fig. 4.
The operation, (see Figs. 2 and 3), of the mech
anisms described is co-operative, unitary, and ef
?cient. As the foot pedal I2 is depressed to raise
device for operating the clamping device, a grip 10
ping and releasing device for the manifold forms
operated by the pedal, means connected to the
pedal for moving the transfer sheets and for
holding the sheets when the pedal is released, and
the form lock bar 9 at the front end of the ma
chine, to permit the release of the forms I from
the hooks 6, the transverse shaft i4 is revolved,
thus lifting the soft rollers l8 with the hooks 25
and relieving the tension on the forms 1 to per
mit them to be drawn freely downward across
the table 2. As the shaft 14 is revolved, it in
turn actuates the shafts 3G and 616, as shown in
Fig. 1. As the transfer sheets 39 are drawn across
the table 2, by action of the gears 51 and 58 and
gears 48 and St, the arms 32 are raised to the
position, indicated in Fig. 5, thus relieving the
tensional strain on the transfer sheets 39, during
the period in which they are moved by the gears
51 and 58. With the pedal 12 in depressed posi
tion, the forms ‘I, which have been ?lled in by the
typewriter, are then removed from engagement
on the hooks 6 and pulled downwardly across the
table 2, until a new set of forms is in position on
the table 2 and engaged on the hooks 6. As the
pedal I 2 is permitted to resume its normal, or
raised position, the soft rollers l8 descend and
in co-operation with the hard rollers II, will
draw the new set of forms taut and flat on the
table 2. At the same time, with the gears 51
means for imparting a tension effect to the trans
fer sheets when the pedal is released.
3. In combination, in a manifold printing ma
chine, three interconnected gear mechanisms,
one for holding and tensioning manifold forms,
one for moving transfer sheets when the tension- 1
ing of the manifold sheets ceases, means for si
multaneously tensioning the transfer sheets when
the tensioning of the manifold sheets occurs
and a pedal device for operating said mecha
nisms.
4. In combination, in a manifolding machine,
a supporting frame, a movable shaft therein, a
pedal for operating the shaft, a roller on the
shaft, asecond shaft, means for raising the sec
shafts operably connected to the pedal, interen
gaging means on two of said shafts between
which the transfer sheets are inserted for mov
ing the sheets, driving means on another shaft
connected to one of the two shafts, ratchet
and 58 held against movement by the ?ne
means on the driving means operable in one
toothed ratchet 65, the arms 32 will move from
direction of rotation and free in another direc
tion of rotation, and means operatively connected
to the pedal for imparting a tension effect to
the transfer sheets.
6. In combination in a manifolding machine
the raised position, indicated in Fig. 5 to the
depressed position, shown in Fig. 4, thereby lat
erally drawing the transfer sheets 39 taut and flat
on the table 2. The amount of movement of the
transfer sheets across the table 2, during each
operation, may be varied by changing the ratio
of the bevel gears 21 and 29, or that of the gears
48 and 5!, or by varying the diameter of the gear
51. The movement of the transfer sheet 39 across
the table 2 may be reversed from that shown and
described by installing the shaft 46 and its co
operating mechanism on the track 3, instead of
the track 4 and installing the shaft 30 and its
co-operating mechanism on the track 4, instead
. of the track 3. This reversed movement may be
desirable in some cases, where it is of advantage
to maintain an unused area of transfer sheets, at
all times, under an important column of ?gures,
or other notations, at the righthand side of the
70 form sheets.
