IMPROVEMENTS IN ROLLING METALS AND IN THE APPARATUS TO BE EMPLOYED THEREIN
Year: 1884

page_text: I CHARLES CHESWRIGHT of Leith Villa, Parkhurst Road Holloway in the County
of Middlesex, Manufacturer do hereby declare the nature of said invention for
IMPROVEMENTS IN ROLLING METALS AND IN THE APPARATUS TO BE EMPLOYED
THEREIN (partly a communication to me from abroad by Henry Cheswright of
Floirac, Bordeaux in the Republic of France and partly my own invention) to' be
as follows:-
This invention which relates more particularly to the rolling or laminating of
tin foil or other metals required to be rolled thin and especially those metals rolled
in packs of sheets, has for its object the simplification of the apparatus and
economy of labour and consists in the application and use of a metal or other
shield or guide curved to suit the top roll, extending from end to end thereof and
covering a portion of its circumference the said shield or guide being firmly
attached in any convenient manner to the standards of the rolls and made
adjustable towards or from the roll surface so as to accomodate between it and the
roll, packs of sheets of different thicknesses. The metal to be rolled or laminated
is introduced between the top of the upper roll and the curved shield or guide and
is guided by the latter to the nip or line of contact between the two rolls and
automatically delivered, by the act of rolling, back to the hands of the workman
in lieu of as heretofore being passed direct between the rolls which necessitated
the employment of a reversing gear and the use of two attendants whereas by the
arrangement above described one workman at the rolls is enabled to do the work
of two. Antifriction rollers are employed in various parts of the shield to
facilitate the passage of the metal. By attaching to the said shield curved
adjustable guiding pieces or ribs of metal or other suitable material situate inside
or underneath the shield provision is made for rolling long or narrow packs of
metal sheets.

I CHARLES CHESWRIGHT of Leith Villa Parkhurst Road Holloway in the County
of Middlesex, Manufacturer do hereby declare the nature of said invention for
IMPROVEMENTS IN ROLLING METALS AND IN THE APPARATUS TO BE EMPLOYED
THEREIN (partly a communication to me from abroad by Henry Cheswright of
Floirac Bordeaux in the Republic of France and partly my own 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 relates more particularly to the rolling of tin foil or other metals
required to be rolled thin and which are usually, rolled in packs of sheets and has
for its object the simplification of the apparatus by dispensing, with the necessity
for reversing gear in connection with the rolls whilst effecting a considerable
economy of time and labour and consists in the use in combination with
continuously revolving rolls of a metal or other curved guide or guides following
the contour of a portion of the circumference of one of the rolls (by preference the
upper one) and extending along a portion or the entire length thereof said curved
guide passing round a portion only (by preference rather less than one half) of the
circumference of the roll at the back thereof and being so placed as to leave a
Bufficient space between it and the surface of the roll for the introduction and
passage of the pack of sheets or other article to be rolled. The said guide is to be
firmly held in position by being attached to any suitable fixed support such for
example as the standards themselves of the rolls and if desired may be made
adjustable towards or from the roll surface. so as to accomodate between it and the
roll articles or packs of different thicknesses. The article or pack to be rolled is
introduced edgewise from the front of the rolls into a mouth formed by the uppor
edge of the said guide above the top roll it is carried, down at the back of the roll
by the rotary motion of the latter, is directed by the guide, between the top and
bottom rolls and is finally delivered automatically by the continuous rotation of
the rolla back to the hands of the workman in front of the machine in lieu of as
heretofore being fed in direct between the rolls which necessitated the employment.
of reversing gear and two attendants to ensure its delivery to the front of the
machine, whereas by the arrangement above described one workman alone at the
front of the rolls is enabled to do the work of two. Antifriction rollers may if
desired be employed in connection with the said, curved guide to facilitate the
passage of the pack or other article but in practico this is not found necessary..
Curved guiding pieces or ribs either fixed or made adjustable towards or from each
other may also be fitted to the inner surface of the before mentioned curved guide
so as to form in conjunction. therewith a mouthpiece for the reception of the packs
or other articles, fed into the machine and to maintain the curved guide at a given
distance from the surface of the roll. These guiding pieces or ribs should be
suitably spaced to suit the length of pack or article to be operated upon.

Figure 1 of the drawings hereunto anuexed represents in vertical transverse
section a portion of an ordinary rolling mill having the aforesaid curved guide

page_text: combined therewith, the driving gear being omitted as being already well
understood. Figure 2 is a separate front elevation of the inner face of the curved
guide here shown as a metal plate, and Figure 3 is a partial horizontal section
and plan of the same.
A, B are a pair of rolls having a continuous rotary motion and mounted in the
usual standards C one of which only can be seen in fig. 1. D represents one of the
pair of screws for regulating the nip or pressure of the rolls actuated by hand
wheels or otherwise as is well understood. E is a table for receiving the rolled
packs a as they are delivered from between the rolls-b is a curved guiding plate
strengthened at the back by being attached at intervals to blocks of wood c
provided with bars d for firmly holding the guide in position-In the drawings
these bars are shown as screwed at their ends to the rear faces of the standards C.
ee are the curved guiding pieces or ribs attached to the inner face of the guiding
plate b and serving not only to keep the pack or article to be operated upon in its
place longitudinally whilst passing round the back of the roll but also to maintain
the desired space between the roll and guiding plate the said ribs e being held in
contact with the surface of the roll. In order to present a convenient mouthpiece
for the reception of the entering pack or article a¹ to be rolled the upper edge of
the curved guiding plate b and the inner sides of the ribs e at the front or entering
end thereof are by preference slightly rounded as shown,
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The combination of curved guide and continuous revolving rolls when arranged
and caused to operate together substantially in the manner and for the purpose
hereinbefore described.
