PROVISIONAL SPECIFICATION.
Improvements in or connected with Machinery or Apparatus for
Polishing or Grinding Rolls used in Tinplate Mills or in Tinning
and other Machines.
We, JOHN HENRY ROWLAND RITSON, of Aberdulais Tin Plate Works, General
Manager, and WILLIAM JENKINS, of Tonna, Mill Foreman, both near Neath in the
County of Glamorgan South Wales, do hereby declare the nature of this invention to
be as follows:-
Heretofore it has been difficult to polish the rolls employed in tinplate mills or in
tinning and other machines when they become rough through wear or from other
causes, without stopping the mill and allowing the rolls to cool down; now the object
of our invention is to remedy this defect or disadvantage by providing means whereby
the roughness on rolls, (which causes the plates to stick and to give them a rough
surface thereby injuring them) is removed with facility, and without, if necessary,
losing time by allowing the rolls to cool down before commencing the operation of
cleaning and polishing the uneven and rough surfaces of the said rolls.
According to our invention we provide polishing apparatus brought up to a
pair of rolls and carried by an adjustable bracket to suit the particular angle to which
the rolls may be set. The polishing material or surface may be composed of any
material or composition suitable for the purpose such as emery. The polishing, block
is made to suit or is curved on each side to correspond with the contour of the rolls
to be polished, and means are provided for adjusting the position to suit the particular
rolls to which it may be required to apply the polishing pads or blocks. This block
may be conveniently carried by a mounting adjustable by set screws or other means,
and the mounting may be carried by a nut provided with suitable guides on a screw
driven by gearing actuated either by hand or power.

COMPLETE SPECIFICATION.
Improvements in or connected with Machinery or Apparatus for:
Polishing or Grinding Rolls used in Tinplate Mills or in Tinning
and other Machines.
We, JOHN HENRY ROWLAND RITSON of Aberdulais Tin Plate Works, General
Manager, and WILLIAM JENKINS, of Tonna, Mill Foreman, both near Neath in the
County of Glamorgan, South Wales, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described:
and ascertained in and by the following statement :-
Heretofore it has been difficult to polish the rolls in tin plate and other machines.
when they become rough through wear or from other causes without stopping the
mill and allowing the rolls to cool down, now the object of our invention is to remedy
this defect or disadvantage by providing means whereby the roughness on rolls,
(which causes the plates to stick and to give them a rough surface thereby injuring
them) is removed with facility and without, if necessary, losing time by allowing
the rolls to cool down before commencing the operation of cleaning and polishing
the uneven and rough surfaces of the said rolls.
According to our invention we provide polishing apparatus brought up to a pair
Poure 8.11

page_text: of rolls and carried by or from an adjustable bracket to suit the particular angle
to which the rolls may be set. The polishing material or surface may be composed
of any material or composition suitable for the purpose such as emery etc. The
polishing block is made to suit or is curved on each side to correspond with the
contour of the rolls to be polished, and means are provided for adjusting the position
to suit the particular rolls to which it may be required to apply the polishing pads
or blocks. This block may be conveniently carried by a mounting adjustable by set
screws or other means and the mounting may be carried by a nut provided with
suitable guides on a screw driven by gearing actuated either by hand or power.
In order that our invention may be fully understood and readily carried into effect
we will now proceed to further describe the same by reference to the accompanying
drawings.
Figure 1 is a vertical cross section of a pair of rolls used in tin-plate and other
machines shewing an arrangement of machinery or apparatus constructed according
to our invention applied thereto for polishing or grinding the said rolls, Figure 2
shews the block and traversing apparatus in plan view, and Figures 3, 4, 5, 6 and 7
are views of somewhat modified arrangements of machinery or apparatus for effecting
a like purpose. Similar letters of reference refer to like parts in all the figures.
A are the surfaces or blocks curved on their surfaces as shewn to adapt themselves
to the size of the rolls. B is the bracket in which the said polishing apparatus is
held, and CC are screws for adjusting the position of same therein. These polishing
surfaces A, bracket B and screws C composing the mounting are carried by and
jointed to a screwed spindle D working through a lug or projecting part on an
internally screw threaded collar or traversing head E on a screw threaded shaft F
the latter having keyed at one end thereof a toothed wheel G in gear with another
toothed wheel H the latter being driven by a handie J or in any other convenient
way. I is the framework in which the screw threaded shaft F revolves. By turning
the handle J the collar or traversing head E on the screw F is traversed length-
ways of the rolls and with it the polishing block and bracket A and B. A pro-
jection E¹ on the collar E takes into a longitudinal groove in the frame I and thus
the collar E and with it the polishing surface is guided longitudinally from end to end
of the rolls. The block A is adjusted towards the rolls by turning the screw Din
the head D' the latter being hinged to the bracket B in order to allow of angular
adjustment of the block A while the latter is itself adjustable in the bracket B by the
screw C.
At Figures 3 and 4 the screw F is arranged centrally in the frame I along which
latter the collar or traversing head E travels when the screw F is revolved. The
screw spindle D is adjustable lengthwise through a shaft K in the traversing head E
and angularly by turning the said shaft K which latter may then be fixed by screw
nut or in other suitable manner.
At Figure 5 the traversing head E is arranged to be worked along the frame I
by rack and pinion as shewn.
At Figures 6 and 7 the traversing head E is mounted and traversed in a similar
way to that shewn at Figure 4 but in this example the shaft K is formed as a
fork and is adjustable on the traversing head E. The fork K carries a spindle L
in bearings adjustable by screw K¹ in the said fork K. M is a pulley on the shaft L
driven by a strap from the roller N the latter being adjustable vertically. The
roller N may be driven by strap and pulley from the axis of one of the rolls also
the screw F may be likewise driven by gearing from the rolls when it is required
to make the apparatus act automatically.
Machinery or apparatus constructed according to our invention is capable of being
applied to grind and polish rolls generally or any particular part thereof.
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 machinery or apparatus for polishing or grinding rolls used in tin plate and

page_text: other machines the polishing surfaces or blocks mounted and carried by traversing
mechanism substantially as and for the purposes set forth.
2. In machinery or apparatus for polishing or grinding rolls used in tin plate and
other machines the arrangements of mechanism described and shewn for regulating
and operating the said polishing surfaces all substantially as herein before described
and illustrated with reference to the accompanying drawings together with any mere
modification or modifications thereof.
