I, ALFRED GERLACH, of 33, Moor Lane, in the City of London, Engineer and
Manufacturer, do hereby declare the nature of this invention (which has been
communicated to me by Friedrich Rehwoldt, of Liepzig-Plagwitz, in the Empire
of Germany, Manufacturer) to be as follows:-
-
This invention relates to improvements in connection with machines which fold
paper any desued number of times.
I will describe the invention as applied to a maclune alanged for folding the
paper either two, or three, times but the invention 18 applicable to tolding paper
other desired numbers of times.
According to this aangement three sets of folding blades and rollers are pio-
vided each set at right angles to the set next preceding, or succeeding, it in the
series, the rolleis being provided with tapes for conducting the papei from one
set of 1ollers to the next, all these may be arranged in the ordinary way
I provide a shaft on which 18 secured a cam (preferably a grooved cam) which, at
different parts of its operative surface, transmits motion to two hooked rods capable
of being engaged with the plunger of the trough, or hopper, which receives the
folded paper
This trough, or hopper may be pivotted so as to enable it to be
moved into different positions in one of which it receives the twice-folded papei
as it leaves the second set of folding rollers, and in another of which it receives
the thrice-folded paper as it leaves the thud set of folding rolleis
The hooked rod for actuating the plunger beneath, say for example, the second
set of folding rollers receives its motion from the before mentioned cam though
suitable 1ods, or links and levels, the first operated of these devices being guided
on the cam shaft by the said shaft passing through a slot therein
The hooked 1od for operating the plunger beneath, say for example, the third
set of folding-rollers is directly operated upon by the cam and is guided on the
cam shaft by the said shaft passing through a slot therein.
When the machine is at work both of the hooked rods are operated and according
as the paper is to be folded two or three times, the trough is adjusted beneath
either the second or the third set of folding rollers and the plunger is connected
to the particular hooked rod appertaining to that set

page_text: communicated to me from abroad by Friedrich Rehwoldt, of Leipzig-Plagwitz, in
the German Empue, Manufacturer) and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment.
-
This invention relates to improvements in connection with machines for folding
paper any desired number of times.
I will describe the invention by reference to the accompanying drawings in
which, as an example, I have represented a machine for folding papei either two, or
three, times; but the invention is applicable to folding paper either desued numbers
of times.
Figures 1 and 2 are sectional elevations taken at light angles to each other
with parts of the machine removed and Figure 3 18 a plan, with the work plate
removed
As shewn in the drawings I provide three sets of folding blades A, B, and C,
and rollers A¹ B and C respectively corresponding therewith, each set at right
angles to the set next pieceding, o succeeding, it in the series, the rollers A¹
and B being provided with tapes, a and b, respectively, for conducting the paper
fiom one set of 1ollers to the next. All these devices may be arranged and
operated in the ordinary way
On a shaft D supported in bearings in the standards E E¹ I secure a cam D¹
(preferably a grooved cam) which, at different parts of its operative surface, tians-
mits motion to two hooked rods f f', capable of being engaged with the plunger 9,
of the trough, or hopper, G, which receives the folded paper. This trough, oi
hopper, G, may be pivotted to a bracket e, rigidly secured to, or formed in pait
with, the standard E, so as to enable it to be moved into different positions, in
one of which positions, as shewn in dotted lines in Figure 2, it receives the twice-
folded paper as it leaves the folding rolleis B¹, and in another of which positions,
as shewn in full lines in Figures 1, 2 and 3, it receives the thrice-folded papei
as it leaves the folding rollers C¹.
The hooked 1od f, for actuating the plunger g (when the hopper G, is arranged
for receiving the twice-folded paper from the olleis B¹) receives its motion from
the cam D through a bell-crank lever f, link f³, bell crank lever ft and link f³
which latter is provided with an anti-fiction 1oller f engaging with the groove
of the cam D and is guided on the cam shaft D by the said shaft passing through
a slot in the link fo as shewn in dotted lines in Figure 1
The hooked rod fi for operating the plunger g (when the hopper G, 18 arranged
for receiving the thrice-folded paper from the 1ollers (") is directly operated upou
by the cam D', and 18 guided on the cam-shaft by the said shaft passing through a
slot therein as shewn in dotted lines in Figure 1
When the machine is at work the two hooked 1ods f f are reciprocated at right
angles to each other, and according as the paper is to be folded two, or three times,
the hopper G is adjusted beneath the folding rollers B or C and the plunger g
is connected to the hooked rod for f.
The tapes ab which, when the paper is being thrice-folded, conducts the latter
successively to the rollers B and C respectively, ae maintained taut by weighted
1ollers a and b acting on bights a*b* of the said tapes at the outside, or other
readily accessible part, of the machine. When the machine is adjusted for folding
the paper twice, the weighted olleis bare disengaged from the tapes 6 and the
latter are moved laterally to withdraw them from the path of the twice-folded paper,
so that the said twice-folded paper may fall directly into the hopper G which is
then beneath the rollers B₁ the tapes at this time being retained in their
inoperative position by a suitable clip e provided say on the standard E' as shewn
in dot-and-dash lines in Figure 2; the clip el is shewn in dot and dash lines in
Figure 1 in the position it occupies on the standard E¹ which is itself omitted
from that figure,
is a projection, or stop, for supporting the hooked rod fi when the latter is
disconnected from the plunger g.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I claim
18:-
1 In a paper-folding machine the combination with two, or more, sets of folding
1ollers, or devices, of a trough, or hopper, adjustable in relation thereto, sub-
stantially as, and for the purpose, herein before described.
2 In a paper folding machine the combination with two, or more, sets of
folding rollers, or devices, and a tough, or hoppei, adjustable in relation theleto,
of means for operating the plunger of the trough, or hopper, in either of the adjusted
positions, substantially as herein before described with reference to the accompany-
ing diawings.
3. In a paper-folding machine the combination with an adjustable tough, or
hopper, and two sets of operating devices, such as f¹ and f, f, f³, f, f³, of a
single cam, such as D' for operating both of such sets of devices substantially as
hereinbefore described with reference to the accompanying drawings.
4. The combination and arrangement of parts constituting the improved paper
folding machine substantially as here before described and illustiated in the
accompanying diawings
