Improvements in Combined Folding and Wrapping Machinery or
Apparatus for Preparing Newspapers, Journals, Prospectuses,
and the like for Postal or similar Purposes.
We FRED WAITE 32 Mount Pisgah Otley in the County of York Printer's
Engineer JASON SAVILLE 106 Tennyson Place Bradford in the aforesaid county,
and JAMES STOTT 16 Jennett's Crescent, Otley aforesaid also Printer's Engineers
do hereby declare the nature of this invention to be as follows:-
This invention, relates to improvements in combined folding and wrapping
machinery, or apparatus for rapidly preparing newspapers, journals, periodicals
pamphlets, prospectuses, circulars, and the like, for postal or similar purposes; and
embodies improvements, whereby the same machine, may be readily adjusted to
fold and wrap papers of different sizes and thicknesses, giving them either one or
two folds, as may be desired to make a suitable form of product.
In previous machines, designed for this purpose, where the folding is accomplished
by means of pairs of rollers, and folding blades, the paper and wrapper, after
receiving the first fold, have been conveyed or guided, by tapes or switches, to a
second pair of rollers and folding blade, to receive the second fold.
In our improved machine, we dispense with the use of tapes and switches between
the two folds, as we mount three rollers in such a position, that the paper and
wrapper, are passed by a folding blade between two of them, to receive the first
fold, and, while still in the grip of these rollers, a second folding blade, which may,
by means of an adjustable cam, be adapted to strike the paper at any desired point,
strikes the paper and wrapper, and doubling them, presses them between one of the
rollers by which they are already gripped, and the third folding roller, so that one
roller assists in giving both folds, and the paper and wrapper are firmly gripped by
the first two rollers, when the second fold is made. Two of the rollers, one for
either fold, are mounted in adjustable spring bearings, so as to be regulatable to
fold thick or thin material.
After receiving the second fold, the wrapper and paper are conducted, by tapes
or their equivalent, into a flap turning device, the wrapper being round the paper
with the gummed flap projecting.
This flap turning device has a gripping side, operated by a tappet, and has a
reciprocating motion imparted to it, to carry the paper to a pair of sealing rollers;
the flap turning device, in its course, being partly rotated against a wiper, so as to
turn down the gunimed flap, when the wrapped paper is gripped by the sealing
rollers, and drawn out of the flap turning device, till the paper is about midway in
the rollers, when the rollers stop and the wrapped paper is held stationary, till the
flap turning device is advancing with another paper, the rollers only discharging
the paper, just in time to be at liberty to take the following paper. Holding
the paper gripped in this manner, keeps the paper from springing out before the
gum is set.
Should only one fold be required, the second folding blade may be disconnected,
and switches inserted, which guide the paper directly into the flap turner, after
receiving one fold.
An improvement embodied in this invention, is the substitution of a catch wheel,
and catch, with a releasing arrangement, for the clutch, as shewn in our previous
Patent (No. 18,810 A.D. 1891).
We have not mentioned the wrapper feeding mechanism, as it is described also in
the same Patent.

page_text: The various parts are relatively operated, by cranks, cams, or equivalent means,
and the folding rollers may be geared together, and all operated by the same spur
wheel.

COMPLETE SPECIFICATION.
Improvements in Combined Folding and Wrapping Machinery or
Apparatus for Preparing Newspapers, Journals, Prospectuses,
and the like for Postal or similar Purposes.
We, FRED WAITE, of 32, Mount Pisgah, Otley in the County of York,
Printer's Engineer, JASON SAVILLE, of Harris Street, Bradford, in said county,
Engineer, and JAMES STOTT, of 16, Jennett's Crescent Otley, aforesaid, Printer's
Engineer, 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 :-
Our invention relates to improvements in combined folding and wrapping
machines for preparing newspapers, journals, prospectuses, pamphlets, circulars
and the like for postal or other similar purposes and particularly to improvements
in the folding and wrapping machine for which Letters Patent were granted to us
on the 31st day of October 1891 Number 18810.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification in which similar letters of reference indicate corresponding parts
in each of the figures.
Figure 1, represents a side elevation of such parts of a wrapping machine as are
necessary to illustrate the application of our improvements.
Figure 2, represents a plan view of the same.
Figure 3, represents a sectional elevation on the broken line a, b Figure 2.
Figure 4, is a view of a detail hereinafter referred to.
The first pair of folding rollers R, R' are geared together by the toothed
wheels X, X and are driven by the broad stud wheel X³ loosely mounted on the
rocking shaft Z' and engaging the toothed wheel X¹ on the main shaft G. The
roller R is mounted in arms Z Figures 1 and 2 rigidly secured to the rocking
shaft Z and a screw stop Z is provided to adjust the distance between them, and a
spring spindle Zo is provided arranged as described in the Specification of the above
cited Letters Patent to bear against the arm Z and tends to press the roller R
towards the roller R with the pressure required. The rollers R and R³ may be fed
with the paper to be folded and a wrapper as described in the above cited Specifi-
cation but instead of passing from these rollers to an independent pair of folding
rollers to give the second fold the roller R is arranged in conjunction with the
roller R to form the second fold. The second folding knife S' is so operated that
as soon as the paper and wrapper has passed sufficiently through the rollers K
and R to bring the line of the next fold in position with the rollers R and R the
said knife doubles the paper and wrapper between them. The folding knife S¹ is
mounted on the arm W vibrated by the box cam W' engaging the anti-friction
roller w carried by said arm. The box cam W' instead of being rigidly keyed on
the shaft G is adjustably secured by the bolts a to the disc plate 6 rigidly fixed on
the shaft G. This construction admits of the cam being partly turned axially to
regulate the time when the knife operated by it makes the second fold. The
roller R is mounted in arms Z* (Figures 2 and 3) similar to the roller R³ and the
wheel X thereon also engages the wheel X.
In case the papers to be folded only require one fold the second folding knife is

page_text: thrown out of operation by moving the arm W along the shaft W' sufficiently to
disengage the anti-friction roller w from the cam W. The metal switch pieces d
are then slipped between the rollers R and R³ and lie in the annular grooves R'
formed in R and R for the purpose of guiding the folded paper from the
rollers R and R' to between the rollers R and R without again folding it.
The rollers are shown in section on a larger scale with the switch in position in
Figure 4.
On leaving the rollers R and R* the folded paper may be carried by tapes to a
third pair of folding rollers or may be passed directly to the flap folding
rollers R, R. These rollers are operated by the wheels X and X' and the latter
is driven by the spur wheel X which instead of being continuously rotated is
intermittently driven by the ratchet wheel X'. The wheel X is not in the same
plane as the wheel X' and is operated from the wheel X by the broad stud wheel x.
The object of driving the delivery rollers intermittently is to retain the paper with
the gummed edge of the wrapper pressed down for an appreciable time between
the rollers to enable the gum to more firmly adhère and the paper is not released
until the interval required to bring another paper into position to pass between
these rollers. The pawl X8 is kept in contact with the ratchet X' by its weight X'
and is mounted on the lever e fulcrumed on the shaft carrying the ratchet X'
and spur wheel X. The lever e is operated by the rod g coupled to the
lever provided with an anti-friction roller i engaging the cam on the shaft G.
Instead of employing the clutch D shown in the above cited Specification for
operating the bottom of the wrapper box to raise and lower the supply of wrappers
we employ a ratchet wheel D fixed on the shaft C* and operated by a pawl D'
mounted on a lever D¹ actuated in a similar manner to the pendent arm cited in the
above cited Specification. The ratchet wheel is moved in the direction of the
arrow (Figure 1) each time the wrappers are lowered to allow the top wrapper to
be fed into the machine and when the motion of the wheel D is reversed and it
has reached the limit of its motion in the reverse direction the pawl D is disengaged
from the ratchet teeth by the lever r. The lever r is provided with a weight at
one end normally resting upon the support projecting from the side frame F and
the inclined nose r of the outer end of the lever is arranged to lie in the path
of the stud projecting from the pawl D' so that on the reverse or return move-
ment of the pawl the said stud rides over the inclined nose and more or less
depressing it raises the other or weighted end of the lever. Immediately however
the reverse motion of the ratchet wheel is arrested, by the supply of wrappers reaching
their upward limit, the pressure of the pawl upon the ratchet teeth is relieved and
under the influence of the weight the lever r returns to its normal position thereby
raising the pawl and disengaging it from the ratchet. By this arrangement the
pawl is smoothly disengaged from the ratchet after each reverse movement and
instead of said pawl always re-engaging the same tooth of the ratchet it enables the
pawl from time to time to pass on to the next tooth as the wrappers are consumed
and the quantity reduced.
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. In a combined folding and wrapping machine, the arrangement or juxta-
position of three folding rollers adapting them to form two folds, substantially as
herein shown and described.
2. The combination with three folding rollers adapted to form two folds, of a
folding knife operated by a cam constructed to be adjusted axially, substantially as
herein shown and described.
3. The combination with three folding rollers adapted to form two folds, of the
switches d arranged to lie in grooves in the second and third rollers and guide the
paper between the first and third rollers without folding it, substantially as berein
shown and described.

page_text: 4. In a folding and wrapping machine, delivery rollers operated intermittently
arranged to retain the wrapped paper with the flap of the wrapper under pressure
for an appreciable time before delivering it, substantially as herein shown and
-described.
5. In the wrapper feeding mechanism of a combined folding and wrapping
machine, the combination with the pawl and ratchet motion of the pawl releasing
lever r, substantially as herein shown and described.
