AN IMPROVED MACHINE FOR STRAIGHTENING AND ROLLING IRON OR OTHER METALLIC Banding
Year: 1871

page_text: LETTERS PATENT to Charles Wallace Chapman, of Liverpool, in the
County of Lancaster, for the Invention of "AN IMPROVED MACHINE
FOR STRAIGHTENING AND ROLLING IRON OR OTHER METALLIC Banding.”
PROVISIONAL SPECIFICATION left by the said Charles Wallace
Chapman at the Office of the Commissioners of Patents, with his
Petition, on the 6th January 1871.
I, CHARLES WALLACE CHAPMAN, of Liverpool, in the County of
Lancaster, do hereby declare the nature of the said Invention for "AN
IMPROVED MACHINE FOR STRAIGHTENING AND ROLLING IRON OR OTHER METALLIC
BANDING," to be as follows:-
My Invention for an improved machine for straightening and rolling
iron and other metallic banding, relates more especially to straightening
or flattening used iron bale banding, so that the banding can be again
turned to account, but the machine is also applicable to straightening
any kind of hoop, or other flat iron.
A machine constructed according to this Invention consists of two
pairs of horizontal rollers, placed one pair before the other, and carried

page_text: or supported on each side by brackets or framework. Each pair of
rollers are arranged in the following manner:-One roller runs in
suitable bearings fixed in the framework, the other roller is placed
over it and runs in bearings which form guide blocks, which guide
blocks work in slots or guides in the framework. On the top of the
guide blocks are suitable bosses or provisions provided with a spring
or buffer of wood, leather, cork, or other suitable material. The other
pair of rollers are fitted in a similar manner and are placed behind
the first pair, the object being for the first pair to straighten or flatten
the banding, the second pair to lead it and prevent it from bending.
Between the two rollers are a pair of parallel guide plates leading
the banding from one pair of rollers to the other, and thereby preventing
the banding running up or down between the rollers. Over the frame-
work on each side are suitable covers, having cast thereon bosses or
provisions through which pass adjustable screwed bolts or studs, working
on to the provisions on the guide blocks before mentioned, and according
to their position pressure is brought to bear from the upper rollers
to the under rollers. The framework or brackets carrying the rollers
may be of any suitable form, carried on a base or tied together by
suitable stays.
The surfaces of the first or front pair of rollers, which may be called
the straightening or flattening rollers are formed in the following
manner: The under roller has a groove or grooves of suitable size, say
about an inch and a quarter, and formed with a slightly concave sur-
face. The upper or pressing 'roller is formed with a collar or collars
which take into the groove or grooves of the under rollers; the collars
may be of about three-quarters or half-inch, or as found expedient in
practise. The surface of the collars is formed slightly convex, and
when the banding is passing through the groove the collar presses the
centre of the band only, avoiding thereby pressure on the sides of the
banding and thereby obviating the danger of lateral deviation. The
second or off rollers have plain surfaces. In some cases both front and
back rollers may be used with plain surfaces.
The rollers may be driven by toothed wheels in the following
manner: A shaft passing between the pairs of rollers carries two pinions
which respectively work into toothed wheels, keyed on to the shafts of
the under rollers on their alternate sides. The shaft passing between
the rollers also carries a larger toothed wheel, which gears into a pinion

page_text: driven by a pulley and strap or other suitable medium. The under
rollers thus being in motion drive the upper rollers by means of pinions
or toothed wheels, gearing the bottom rollers to the top rollers.. The end
of banding (say, used cotton bale banding, which becomes much bent
and crushed in the act of opening the bale) to be acted upon is inserted
in the grooves of the front under rollers, the collar of the front upper
roller pressing on the centre of the banding straightens it as it passes.
It is thence led by the guide plates through the second or back
rollers, which deliver it straight and free from bends."

for AN IMPROVED MACHINE FOR STRAIGHTENING AND ROLLING IRON OR OTHER
METALLIC BANDING," upon the condition (amongst others) that I, the said
Charles Wallace Chapman, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals, should
particularly describe, and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent..

page_text: NOW KNOW YE, that I, the said Charles Wallace Chapman, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
:-
My Invention for an improved machine for straightening and rolling
iron and other metallic banding relates more especially to straightening
or flattening used iron bale banding, so that the banding can be again
turned to account, but the machine is also applicable to straightening
any kind of hoop or other flat iron.
A machine constructed according to this Invention consists of two
pairs of horizontal rollers, placed one pair before the other, and carried
or supported on each side by suitable brackets or framework. Each pair
of rollers are arranged in the following manner:-One roller runs in
suitable bearings fixed in the framework, the other roller is placed over
it and runs in bearings which form guide blocks, which guide blocks
work in slots or guides in the framework. On the top of the guide
blocks are suitable bosses or provisions provided with a spring or buffer
of wood, leather, cork, or other suitable material. The other pair of
rollers are fitted in a similar manner and are placed behind the first pair,
the object being for the first pair to straighten or flatten the banding, the
second pair to lead it and prevent it from bending. Between the two
rollers are a pair of parallel guide plates leading the banding from one
pair of rollers to the other, and thereby preventing the banding running
up or down between the rollers. Over the framework on cach side are
suitable covers having cast thereon bosses or provisions through which
pass adjustable screwed bolts or studs working on to the provisions on
the guide blocks before mentioned, and according to their position
pressuro is brought to bear from the upper rollers to the under rollers.
The framework or brackets carrying the rollers may be of any suitable
form carried on a base or tied together by suitable stays.
The surfaces of the first or front pair of rollers, which may be called
the straightening or flattening rollers, are formed in the following manner:
-The under roller has a groove or grooves of suitable size, say inch and
a quarter, and formed with a slightly concave surface. The upper or
pressing roller is formed with a collar or collars, which take into the
groove or grooves of the under rollers; these collars may be of about
three-quarters or half-inch or as found expedient in practise. The
surface of the collars is formed slightly convex, and when the banding is

page_text: passing through the groove the collar presses the-centre of the band only,
avoiding thereby pressure on the sides of the banding, and thereby
obviating the danger of lateral deviation. The second or off rollers have
plain surfaces. In some cases both front and back rollers may be used
with plain surfaces.
The rollers may be driven by toothed wheels in the following manner:
-A.shaft passing between the pairs of rollers.carries two pinions which
respectively work into toothed wheels keyed on to the shafts of the under
rollers on their alternate sides. The shaft passing between the rollers
also carries a larger toothed wheel which gears into a pinion driven by a
pulley and strap or other suitable medium. The under rollers thus being
in motion drive the upper rollers by means of pinions or toothed wheels
gearing the bottom rollers to the top rollers.
i
The before going being the nature and object of my Invention I will
now describe more in detail how the same is to be or may be performed
or carried out into practical effect, and in order that the same may be
more clearly and readily understood, I have hereunto annexed a Sheet of
Drawings illustrative thereof, marked with figures and letters of reference
corresponding with those in the following explanation. Like letters and
figures are used to denote similar parts :-
Figure 1 is a sectional elevation of a machine constructed according
to my Invention; Figure 2 is an outside elevation of the same; Figure 3
is a plan, and Figure 4 an end view.
It will be seen upon reference that tlie machine consists of two pairs
of horizontal rollers A, A, B, and B', carried and supported by brackets
'C and C. Each pair of rollers being arranged as follows:-The roller A
runs in suitable bearings D fixed in the brackets, which bearings form
guide blocks which work in the slots or guides E in the brackets C.
The roller A' runs in suitable brasses F fixed in the framework and under
the roller A. The rollers B and B are fitted and run in a similar
manner. On the top of the guide blocks D are fitted hollow bosses or
provisions G provided with a spring or buffer of wood, cork, leather, or
other suitable substance. Fitting into these hollow bosses are screws H,
which are screwed through strong covers I, which covers are bolted
firmly to the brackets C. Between the rollers are a pair of parallel

page_text: guide plates K and K leading the banding from rollers, A and A¹ to
rollers B and B¹. L is a guide piece which is fixed between the brackets
C and C¹ and has slots M for the banding to be passed through. N stays
holding or securing brackets C and C¹ together. The machine is driven
by a strap working on to pulley O, which pulley is carried on shaft P.
Q pinion, which gears into toothed wheel R, which is carried on shaft S.
This shaft also carries pinions T and T', which gear respectively into
toothed wheels U. and U', which are fitted on to rollers A and B
respectively. The under rollers being thus put in motion work the upper
rollers by means of the toothed. wheels. V and V₁ and X and X'. It will
be seen that the surfaces of the rollers A and A', which may be called
the straightening or flattening rollers, are formed in the following.
manner: The under roller. A¹ has grooves a, a, a; of suitable size, say
inch and a quarter, and formed with a slightly concave or flat surface.
The upper or pressing roller A has collars b, b, b, which take into the
grooves a, a, a, of the under roller: The surface of the collars is formed
slightly convex, so that when the banding is passing through the groove
the centre of the band only is pressed; avoiding thereby the danger of
lateral deviation. The second or off rollers B and B₁ have plain surfaces.
In some cases both front and back rollers may be used with plain
surfaces.
The action of the machine is thus:-The end of banding (say used.
cotton bale banding, which becomes much bent and crushed in the act
of opening the bale), to be acted upon is inserted through the slots M in
the guide L, thence to the grooves a of the front or under roller A', the
collars 6 of the front or upper roller A pressing on the centre of the
banding straightens it as it passes; it is then led through the parallel
guide plates K and K', and through the second or back rollers B and B',
which deliver it straight and free from bends.
Having, now described the nature and object of this, my Invention,.
and the manner in which the same is to be or may be performed or
carried out into practical effect, I would have it understood that I do not
limit myself to the exact dimensions and relative proportions of the
machine, as shown in the Drawings, as it will be seen that they may be
considerably varied without departing from my Invention, but what I
claim as the Invention, secured to me by Letters Patent as aforesaid
is, the construction, arrangement, and combination herein shown and
.

In witness whereof, I, the said Charles Wallace Chapman, have
hereunto set my hand and seal, this Twenty-ninth day of June,
in the year of our Lord One thousand eight hundred and seventy-
one.
