Year: 1871

page_text: LETTERS PATENT to William Bradbury Robinson, of Chesterfield, in
the County of Derby, Pill Box Manufacturer, for the Invention
of "IMPROVEMENTS IN THE MANUFACTURE OF THE CYLINDERS OR RINGS OF
BOXES MADE FROM WOOD SHAVINGS OR CHIPS, OR FROM STRIPS OF PASTEBOARD
OR PAPER."
Sealed the 30th January 1872, and dated the 28th August 1871.
PROVISIONAL SPECIFICATION left by the said William Bradbury
Robinson at the Office of the Commissioners of Patents, with
his Petition, on the 28th August 1871.
I, WILLIAM BRADBURY ROBINSON, of Chesterfield, in the County of
5 Derby, Pill Box Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF THE CYLINDERS OR
RINGS OF BOXES MADE FROM WOOD SHAVINGS OR CHIPS, OR FROM STRIPS OF
PASTEBOARD OR PAPER," to be as follows:-
It has been customary to make what are known as willow or chip
) boxes by hand by wrapping the shaving or strip around a mandril

page_text: Having a longitudinal suit in it, putting a little glue under one end of
the shaving and then fastening the ends together with a wire spring or
peg.
My Invention has for its object the more rapid production of the
rims, hoops, or rings of willow, chip, or pasteboard boxes, or for the
making of rims of boxes from shavings of any kind of wood sufficiently
tough to bend round a mandril. For this purpose I mount a mandril
(the proper size of the rim to be made and having a longitudinal slit
or recess on its surface) on a spindle or shaft fitted to suitable bearings
attached to the frame of the machine. On the mandril is carried a
finger, this finger is held down on to the mandril by a spring, and at
the proper time is held away from it by a cam, or is otherwise held
down and liberated at the requisite times. When the finger is being
held away from the mandril, a shaving or strip is passed a short
distance under it. The finger is then allowed to grip the shaving
to the mandril, and by the revolution of the mandril it is carried
round with it. Other fingers receiving motion from springs or weights
and cams, or otherwise actuated, press the shaving to the mandril, so
that it may be wrapped closely around it, and such finger or fingers also
hold the shaving fast after it has been wrapped around the mandril,
and whilst a wire spring or peg is forced over the overlapping ends
of the wood or cardboard strip, which wire peg is to hold the hoop
together whilst the glue sets. After the mandril has made ono revo-
lution and a strip has been wrapped around it as above described, it
remains stationary for an interval, whilst the wire peg is forced on
to the rim, which is done by a pusher or bolt which pushes the peg
before it. The wire pegs are brought up to the bolt which forces them
on the shaving one by one as required, by being placed side by side on
an endless band, or they may be placed in suitable trough and pushed
forward by a weight. The pusher or bolt has attached to it other 3
fingers or bolts which, after the peg has got a sufficient distance on
the rim or cylinder, push tho rim or cylinder with the peg upon it off
the mandril, the bolts are then withdrawn by a spring leaving the
mandril ready for forming another cylinder. The necessary alternate
revolving and stationary action of the mandril is caused by suitably 3
spaced toothed wheels, or by friction rollers or bands or straps with an
escape motion attached.

page_text: The shavings may be fed to the mandril by hand or by suitable
feeding mechanism. I prefer to employ for this purpose a pair of
rollers which are parallel to the mandril, these rollers receive an inter-
mittent revolving motion in the same manner as the mandril. One
of the rollers is hollow with a longitudinal slot in it, through which
the glue is passed to the shaving as it is being passed forward on to
the mandril.
Several methods of applying the glue to the shaving can be adopted.
Provision is made for throwing the glueing apparatus out of action,
should there be no strip of wood or paper or cardboard passing between
the rollers.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Bradbury Robinson in the Great Seal
Patent Office on the 26th February 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BRADBURY ROBINSON, of Chesterfield, in the County of Derby, Pill
Box Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of August, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Bradbury Robinson, Her
special license that I, the said William Bradbury Robinson, my
executors, administrators, and assigns, or such others as I, the said
William Bradbury Robinson, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN THE MANUFACTURE OF THE
CYLINDERS OR RINGS OF BOXES MADE FROM WOOD SHAVINGS OR CHIPS, OR FROM
STRIPS OF PASTEBOARD OR PAPER," upon the condition (amongst others) that
I, the said William Bradbury Robinson, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the

page_text: said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Scal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said William Bradbury Robinson, do
hereby declaro the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say :—
It has been customary to make what are known as willow or chip
boxes by hand by wrapping the shaving or strip around a mandril
having a longitudinal slit in it, putting a little glue under one end
of the shaving and then fastening the ends together with a wire spring
or peg.
My Invention has for its object the more rapid production of tho rims,
hoops, or rings of willow chip or pasteboard boxes, or for the making
of rims of boxes from shavings of any kind of wood sufficiently tough
to bend round a mandril. For this purpose I mount a mandril (tho
proper size of the rim to be made, and having a longitudinal slit or
recess on its surface,) on a spindle or shaft fitted to suitable bearings
attached to the frame of the machine. On the mandril is carried a
finger; this finger is held down on to the mandril by a spring, and at
the proper time is held away from it by a cam, or is otherwise held down
and liberated at the requisite times. When the finger is being held
away from the mandril, a shaving or strip is passed a short distance
under it; the finger is then allowed to grip the shaving to the mandril,
and by the revolution of the mandril it is carried round with it.
Other fingers receiving motion from springs or weights and cams, or
otherwise actuated, press the shaving to the mandril, so that it may
be wrapped closely around it, and such finger or fingers also hold the
shaving fast after it has been wrapped around the mandril, and whilst :
a wire spring or peg is forced over the overlapping ends of tho wood
or cardboard strip, which wire peg is to hold the hoop together whilst
the glue sets. After the mandril has made one revolution, and a strip
has been wrapped around it as above described, it remains stationary
for an interval, whilst the wire peg is forced on to the rim which is
done by a pusher or bolt which pushes the peg before it. The wire pegs
are brought up to the bolt, which forces them on the shaving one by

page_text: gearing with a wheel dª, which has teeth omitted from a space in its
circumference. There is also a projection on the side of the wheel &,
which striking another projection on the wheel d', throws this wheel into
gear at the proper time. and are notched discs on the axes c and d.
The spring pressers c³ and & bear against them to retain the axes when
they are not driven by the gearing. 'is a cam on the shaft ; it gives
a to-and-fro motion to the slide e by means of a lever e¹, turning on an
axis at e¹. e³ is a link connecting the lever with the slide. The other
cams on the shaft & are the cam & for working the glucing apparatus,
and the cains bª, 67, and 6' for working the instruments which assist in
lapping the strip of wood or pasteboard around the mandril. This strip
is fed by hand into the machine to the nip of the feed rollers d' and d³,
the guide plate aiding the workman in presenting tho strip truly to
the rollers. The axis dª of the upper foed roller is pressed downwards
by a spring or weight, and is geared by the pinions with the axis d.
At the proper time the feed rollers start into movement, and the feed
rollers pass the end of the strip forward to the mandril g, and its end
enters under the gripping finger g', and projects beyond it a short
distance. The gripping finger g' is at this time lifted against the
resistance of the gripper spring g₁ by the lever h, which is raised by
the cam 6. The form of the gripping finger and its spring, and also
of the mandril is clearly seen in Figures 5. When the strip is under
the gripping finger, the gripping finger descends and scizes it, and the
mandril commences to revolve. The pressing finger i turns upon a
centre at ¹, and has a spring arm , bearing on the cam 67. This finger
being brought down on to the strip as soon as the gripping finger has
passed it, causing the strip to lap tightly upon the mandril. j is another
finger acting in a similar manner, but of a different shape; it is caused
by the cam 68 to press upon the mandril as soon as the gripper has
passed. When the winding of the strip upon the mandril is nearly
complete, the pressing finger i rises by the action of the counterpoise ³,
to let the following end of the strip pass under it, whilst the strip
continues to be held close to the mandril by the finger j, and this done,
it descends again, pressing together the two ends of the strip which
are then both beneath it. The following end of the strip is touched
with gluc before this part of the strip reaches the mandril as it leaves
the feed rollers. The lower feed roller is hollow and has a slit in it, and
the glueing lever & projects into it. This lever is mounted on an axis k³,
and when the lever is in its lower position, its end is immersed in melted

the slide m to be moved forward by a weight or spring connected with
it, and it then acts on an arm on the axis k', and lifts the end of
the lever / out of the glue into contact with the end of the strip; which
is held between the feed rollers. When the lapping of the strip upon
the mandril is completed the rotation of the mandril ceases; the
slido e advances, and the bolt e' which forms part of it pushes forward
a peg or clip n, which is then standing in front of the bolte. The
peg or clip is thus pushed over the two overlapping ends of the strip
upon the mandril. At this time the pressing finger i is caused to bear
heavily on the ends of the strip by the cam b', so that the strip' may
not be moved by the peg or clip being thrust upon it.
or clip is placed on the ring or hoop, the other bolts or pushers eª, e^,
also carried by the slide e have advanced up to the ring, and in their
further motion they push it off the mandril at the same time that the
bolts e, e', touch the ring, the figure g¹ is raised by the cam 6º and the
fingers ; & ; are released by the cams 6º, 6³; and lifted off the ring by
the action of springs or weights. The peg or clip n is of the ordinary
sort; it is shewn at Figure 6, which also represent a ring or hoop as it
is discharged from the machine, with its ends held together by the peg.
The pegs or clips are brought forward in succession in front of the
bolt e by the endless band o-and guides p on which they lie. This
band passes round a drum o¹ with a ratchet wheel o' on its axis, and a
pawl σ on a rod of drives the wheel and gives a slow step by step
motion to the band. The rod o' takes its movement from an eccentric.
on the axis b. In order that the upper feed roller d³ may not be soiled
by the glue when the workman omits to feed a strip into the machine, a
fecler q is applied. At cach rotation of the mandril it is raised by
a cam & and then allowed to descend. If the strip is in its place
between the feed rollers and passing on to the mandril the feeler is
soon stopped by coming against the strip, but if not the feeler descends
lower and a hook at its end then catches the arm ³ on the axis k¹ of the
glue lever k and retains the glueing apparatus out of action.
Having thus described the nature of my said Invention, and the
manner of performing the same, I would have it understood that I.
do not confine myself to the exact details described, but I claim as
my Invention of improvements in the manufacture of the cylinders
