We, HERBERT JAMES SALMON, of Woodley Iron Works, near Stockport,
in the County of Chester, Engineer, JOHN CAPPER and JAMES DEAVILLE of
the same place, Engineers, do hereby declare the nature of the said invention,
to be as follows:-
In folding machines making three folds, when a fourth fold is to be made paralle!
to the third, our invention consists in combining a folding knife actuated by a cam
on any suitable rotary part of the machine and connected mechanism, with the
delivery rollers for the third fold, in order to make a fourth fold parallel to the
third fold.
Improvements in or applica
We, HERBERT JAMES SALMON of Woodley Iron Works, near Stockport, in
the County of Chester, Engineer, JOHN CAPPER and JAMES DEAVILLE of the
same place, Engineers, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
In folding machines making three folds, when a fourth fold is to be made parallel
to the third, our invention consists in combining a folding knife actuated by a cam
on any suitable rotary part of the machine and connected mechanism, with the
delivery rollers for the third fold, in order to make a fourth fold parallel to the
third fold.
Fig. 1, is an elevation partly in section, the section being in a plane at a right
angle to the axes of the third and fourth folding rollers, the latter making the
fourth fold downwards parallel to the third.
Fig. 2, is a sectional elevation showing a combination for making a fourth fold
parallel to the third fold, the sheet being folded upwards.
These views show so much of the mechanism of a folding machine as will be
necessary to illustrate our invention.
a, is the framing of the machine; b, is one of the hinged tables upon which the
paper to be folded is placed for the first fold the sheet descends vertically being
carried by tapes from the first pair of folding rollers until the fold comes against
a stop when the second fold is made, the knife for which drives it between the
second folding rollers, the axes of which are in a vertical position and it is carried
hy tapes along the vertical face of the plate a, having a slot a, in it, until it
comes against a stop when the third folding knife drives it through the slot a', and
between the third pair of folding rollers 1, from which the third folded sheet is

page_text: carried horizontally by tapes to the fourth pair of folding rollers and r¹, the
axes of which are horizontal and in the same plane as the third folding rollers
consequently the third folded sheet receives its fourth fold parallel to the third
fold.
When required the same machine is or may be arranged to give a fourth fold
either upwards or downwards at a right angle to the third fold by having folding
rollers arranged accordingly opposite a slot in the plate a', but our present invention
does not relate to the latter arrangement, but to making the fourth fold parallel to
the third fold either upwards or downwards.
The third folded sheet is carried by endless tapes over the surface of the
table aº.
The lower set of tapes ², extend from the lower third folding roller to the
nearest fourth folding roller (r) and the upper set ³, extend from the upper third
folding roller to a tape carrying roller, in bearings near the folding roller r.
The third folded sheet is carried by the tapes over the fourth folding rollers r
and, until it comes against an adjustable stop, on the table ad, when the knife s,
drives it downward between the fourth folding rollers and r.
This knifes, is carried on arms s', on a shaft s², in bearings on the framing.
This knife s, is or may be worked by an arm s³, on the shaft s2, shown in dotted
line connected by a rod indicated by a centre line s, with one arm of a bell crank
lever s, having its fulcrum so, on the framing, the other arm of the bell crank lever
being connected by a rod with a lever on a suitable fulcrum carrying a bowl acted
upon by a cam or crank on the cam shaft d³, or on the cam shaft d, at a right angle
thereto both in ordinary use in folding machines.
The cam and levers is or may be arranged to lift the knife s, and allow it to
descend by its own weight or assisted by a spring.
When the sheet descends through the fourth folding rollers, it comes opposite
the face of a pusher t, which moves to and fro on brackets a*, secured to the
framing to drive the sheet into a packing box, not shown, and when the sheet is
pushed into the packing box by the front edges of a series of vertical ribs t', on
the pusher, the prongs t², on bar, connected with a part t', that can slide on a
vertical guide to, to come into the spaces between the vertical ribs t', on the pushert,
and thus prevent the sheet pushed into the packing box from following the pusher
when it is moved back ready to receive the next sheet, the prongs being drawn
down a little after the sheet begins to descend in front of the ribs of the pusher.
This packing box arrangement and the pusher t, and prongs 2, and mode of
working them from the cam shaft of the machine is ordinary and well known and
does not require further description.
In the modification illustrated by Fig. 2-the lower set of tapes from the lower
third folding rollers passes round a tape carrying roller s³, nearly under the fourth
folding roller r, which is nearest the third folding rollers, and the upper set of tapes
pass from the upper third folding roller to the nearest fourth folding roller r, so
that the third folded sheet passes under the fourth folding rollers and then over a
table a", to an adjustable stop
The fourth fold is driven by the knife s, upwards, between the folding rollers r
and r¹.
There is a lower set of carrying strings or tapes from the folding roller r, to a
tape or string carrying roller, and another upper set of tapes or strings from
the folding roller r, passing against the roller r, then against the roller, under
the roller, and back over the rollers 8 and r, to the roller r.
Thus arranged the up folded sheet is carried to rollers, and, which pass it
vertically downwards in front of a pusher t, for a packing box with prongs 2, as
hereinbefore described in reference to Fig. 1.
The knife s, is operated to act upwards, and the cam, levers and connections
between the levers are arranged accordingly, the knife is or may be arranged to
act upwards by weights or a spring and to be drawn downwards by the positive
action of the cam.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The combination of mechanism with folding machines to give a fourth fold
parallel to the third fold with the fold either upwards or downwards, substantially
as hereinbefore described and illustrated by the drawings.
2. The combination of mechanism with folding machines to give a fourth fold
parallel to the third with the fold either upwards or downwards and with mechanism
for placing the folded sheets in a packing box substantially as hereinbefore
described and illustrated by the drawings.
