Improvements in Machinery for Rolling Lead or other Ductile Metal
Strips for Glazing Purposes.
I, WILLIAM HENRY SUTTON, of 7, Bath Street, Birmingham, Warwickshire, General
Tool Maker, do hereby declare the nature of this invention to be as follows:-
This invention has reference to machinery for rolling those kind of lead or other
ductile metal strips for glazing purposes which in section somewhat resemble the
letter H the said strips being used for securing small pieces of glass together for
making stained and other ornamental glass windows or lights.
The object of rolling the said strips is to reduce them to their proper size in cross
section.
The machinery as at present commonly used for this purpose consists of two rolls
revolving in a vertical plane between which the lead or other metal strip is passed
these rolls acting upon the central web of the strip the sides of the strip mean while
being supported by a pair of fixed plates or checks which are grooved to suit the
required strip. These grooved plates are difficult to adjust and are expensive to
renew when worn.
According to my invention instead of supporting the sides of the strip by two fixed
grooved plates as heretofore I employ a pair of grooved rolls the axes of which
are at right angles to the vertical rolls above mentioned for acting upon the central
web of the strip.
Each of these horizontal rolls is free to revolve upon a pin carried by an arm
adjustably fixed to the frame of the machine so that the horizontal rolls can be
moved either nearer to or farther from the vertical rolls and fixed in the required
position to suit the strip which is being operated upon. The said horizontal rolls
inay either be loose on their axes so as to revolve as the strip passes between
them or they may be fixed by a central nut or by other means so that when one
part of these rolls is worn they can be turned round through a small space and
again fixed to bring a fresh part into use thereby enabling them to last for a long
time before they required to be trued up again.
In order to disponse with the necessity of employing a separate pair of rolls for
each of the different sizes of strips to be operated upon I sometimes divide the
periphery of the rolls into sections the groove in each section being slightly larger
than that in the preceeding one. The rolls are notched or otherwise formed so
that they can be fixed for any particular section to be used corresponding with the
size of strip to be operated upon.

Improvements in Machinery for Rolling Lead or other Ductile Metal
Strips for Glazing Purposes.
1, WILLIAM HENRY SUTTON, of 7, Bath Street, Birmingham, Warwickshire, General
Tool Maker, 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 :--
This invention has reference to machinery for rolling those kind of lead or other
ductile metal strips for glazing purposes which in section somewhat resemble the

page_text: letter H the said strips being used for securing small pieces of glass together for
making stained and other ornamental glass windows or lights.
The object of rolling the said strips is to reduce them to their proper size in
cross section.
The machinery as at present commonly used for this purpose consists of two rolls
revolving in a vertical plane. between which the lead or other metal strip is passed
these rolls acting upon the central web of the strip the sides of the strip meanwhile
being supported by a pair of fixed plates or cheeks which are grooved to suit the
required strip. These grooved plates are difficult to adjust and are expensive to renew
when worn.
According to my invention instead of supporting the sides of the strip by two fixed
grooved plates as heretofore I employ a pair of grooved rolls the axes of which are at
right angles to the vertical rolls above mentioned for acting upon the central web of
the strip.
On the accompanying drawings Fig. 1 is a front view, Fig. 2 a cross sectional
elevation, Fig. 3 is a back view and Fig. 4 a sectional plan of a machine for rolling lead
or other ductile metal strips for glazing purposes constructed according to this
invention; Fig. 5 shews a section of lead strip which is rolled by the said machine;
Fig. 6 represents parts of the machine on an onlarged scale; Fig. 7 shews a modified
form of the said invention and Figs. 8 and 9 represent a further modification.
The same letters of reference indicate the same or corresponding parts in all the
Figures of the drawings.
and
The two ordinary milled rolls, which act upon the central web of the lead or other
ductile strip a, are marked respectively 61 62, they are formed with spindles e revolving
in bearings in the side frames d' d' and geared together by the spur wheels ele as
usual. The lead or other ductile metal strip a to be rolled passes between these rolls
in the direction indicated by the arrows in Figs. 2 and 4. The two horizontal rolls
which I provide for supporting the sides of the strip are marked flf. Their axes g
are respectively carried by the forked arms which fit in holes i in the side
frames d' d' so that by the adjusting screw ; acting upon the end of the arm the
rolls can be moved either nearer to or farther from the vertical rolls
fixed in the required position by the set screws to suit the width of strip to be acted
upon. are two taper grooved guides each provided with a shank m fitting in a
hole in the side frame and there secured by the set screw n. By means of the
screws o¹ o² the guides 1 12 can be adjusted to the proper distance apart. The object
of these grooved guides 12 is to break down or reduce the strip before passing
through the finishing rolls ff. p is an adjustable guide behind the rolls for keeping
the finish strip straight. The rolls f¹ f2 have to be grooved at q to suit the shapo
of the strip which is required to be rolled as will be understood. These rolls may
either be loose on their axes as illustrated so as to revolve as the strip passes
between them or they may be fixed by a central nut on their axes which cramps
the jaws of the arms together so that when one part of the groove q in these rolls
is worn, the rolls can be turned round through a small space and again fixed to
bring a fresh part into use thereby enabling them to last for a long time before
they require to be trued up again.
In the modification illustrated by Fig. 7 the taper guides 11 12 are dispensed with
and instead thereof an additional pair of grooved rolls 2012 are used for breaking
down and guiding the strip these rolls being by preference mounted similarly to the
rolls f¹f
In order to dispense with the necessity of employing a separate pair of the
rolls for each of the different sizes of strips to be operated upon, as would be
necessary if the grooves 7 are turned therein, I sometimes divide the peripheries of
the rolls into sections, the groove in each section being slightly larger than that
in the preceding one. These rolls will thus be triangular, square or polygonal instead
of being round and they are notched or otherwise formed so that they can be fixed
for any particular section to be used corresponding with the size of the strip to be
operated upon. This modification is illustrated by Figs. 8 and 9 where each of the

page_text: rolls ff is divided into four sections each grooved slightly larger than the preceding
one so as to serve for four different sizes of strips. Their central pins are made square
to prevent them turning round. By first removing these pins either section can be
brought into use as may be required.
The side framed of the machine is made removable by the screws so as to enable
the various parts to be changed or renewed.
The rolls used as above described present a much larger wearing surface to
the strip which is being operated upon than do the grooved cheeks heretofore used and
consequently they last much longer in wear and they are also less expensive to make
than are the said cheeks.
The accompanying drawings illustrate what I consider to be the best way for
carrying my said invention into effect but it is to be understood that I do not limit
myself to the precise details illustrated as the same may be varied without departing
from the nature of my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what I
claim is :-
1. In a machine for rolling lead or other ductile metal strips of H section for
glazing purposes the combination with the two milled rolls which act upon the
web of the strip of a pair of adjustable grooved rolls f1 f arranged to operate on the
said strip as it is being rolled substantially as and for the purpose herein before
described and illustrated by the accompanying drawings.
2. The general construction and arrangement of parts constituting a machine for
rolling lead or other ductile metal strips of H section for glazing purposes as
hereinbefore described and illustrated by Figs. 1, 2, 3, 4 and 6 of the accompanying
drawings and the modifications hereinbefore described and illustrated respectively by
Fig. 7 and by Figs. 8 and 9.
