PROVISIONAL SPECIFICATION.
Improved Machinery for Cleaning Tin and Terne Plates.
We, WILLIAM WILLIAMS, of 1, Bryn, Pontardulais, Tin-house Superintendent,
JONATHAN WILLIAMS, of 2, Brookland Terrace, Pontardulais, Millwright, and
REES HARRIES, of Bolgoed, Pontardulais, Tin-plate Works Manager, do hereby
declare the nature of this invention to be as follows:-
:―
This invention consists in improved machinery for cleaning tin and terne plates.
According to this invention, the plates, after they have been passed through the
bran trough are fed to a pair of rolls carried in bearings in standards and coated
with india-rubber, gutta-percha, vulcanite or like substance. By these rolls, which
are made to rotate at the same speed, each plate is, in turn, impelled towards and
delivered between a pair of sheepskin-covered rolls situated at a distance from the
feed rolls corresponding to less than half the width of the smallest class of plate
which the machinery is designed to clean. In the passage of the plate between the
latter pair of rolls, which are rotated at a higher speed than the feed rolls, a part
of both faces is cleaned, the cleansing action continuing only while the plate is in
the grasp of the feed rolls. When freed therefrom the cleaning action ceases and
the plate is carried forward by the sheepskin-covered rolls and being delivered
into an inclined guide is thereby directed to descend to a second pair of feed rolls
similar to those first above described and similarly coated. The guide is so set
that the uncleaned part of the plate is first presented to the second pair of feed
rolls. These latter are set at an angle, and by them the plate is impelled towards
and delivered to a second pair of sheepskin-covered rolls set at a corresponding
angle to the second pair of feed rolls, the distance between the two pairs being
determined as in the pairs of rolls above. In the passage of the plate through the
second pair of sheepskin-covered rolls the previously uncleaned part of both faces
of the plate is cleaned in the same way as above described with reference to the
part first cleaned.
The bodies of the cleaning rolls preferably consist of wooden drums carried on
steel or iron spindles, and the various pairs of rolls are so geared that the feed rolls
and cleaning rolls in one set rotate at the same speed as the corresponding rolls in
the other set."
The upper roll of each pair of sheepskin-coated rolls is adjustable apart from
the lower by means of a spiral spring placed between the bearings and controlled by
a regulating screw.

Improved Machinery for Cleaning Tin and Terne Plates.
We, WILLIAM WILLIAMS, of 1, Bryn, Pontardulais, Tin-house Superintendent,
JONATHAN WILLIAMS, of 2, Brookland Terrace, Pontardulais, Millwright, and
REES HARRIES, of Bolgoed, Pontardulais, Tin-plate Works Manager, 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 consists in improved machinery for cleaning tin and terne plates.

page_text: According to this invention, the plates, after they have been passed, as is usual,
through the bran trough, are fed to rolls carried in bearings on a suitable frame.
By these rolls, which are made to rotate at the same speed, each plate is, in turn,
impelled towards and delivered between a pair of sheep-skin-covered rolls situated
at a distance from the feed rolls corresponding to less than half the width of the
smallest class of plate which the machinery is designed to clean. In the passage of
the plate between the sheepskin-covered rolls, which are rotated at a higher speed
than the feed rolls, a part of both faces is cleaned, the cleansing action continuing
only while the plate is in the grasp of the feed rolls. When freed therefrom the
cleaning action ceases and the plate is carried forward by the sheepskin-covered
rolls and, being delivered on to an inclined guide, is thereby directed to descend to
a second set of feed rolls. The guide is so placed that the plate is thereby
presented to the lower set of feed rolls with the uncleaned part leading. The said
feed rolls are set at an angle, and by them the plate is impelled towards and
delivered to a second pair of sheepskin-covered rolls set at a corresponding angle to
the lower set of feed rolls; the distance between the feed rolls and the cleaning
rolls being determined as in the sets above. In the passage of the plate through
the lower pair of sheepskin-covered rolls the previously uncleaned part of both
faces of the plate is cleaned in the same way as above described with reference to
the part first cleaned.
In the accompanying drawing, Fig. 1 represents in vertical section and Fig. 2 in
end view our improved machinery for cleaning tin and terne plates.
The plates as they are taken from the bran trough are presented in succession to
the feed rolls a carried on spindles & supported in bearings c secured on the frame d.
The rolls a may consist of wooden drums covered with india-rubber or the like.
They are rotated at equal speed. By the rolls a each plate is in turn impelled
towards and delivered between the rolls e which may consist of wooden drums and
are coated with sheepskin or the like. The rolls e which are carried on spindles f
supported in bearings g fixed on the frame d are situated at a distance apart from
the rolls a corresponding to less than half the width of the smallest class of plate
which the machinery is designed to clean. The rolls e are rotated at a higher
speed than the rolls a. In the passage of a plate between the rolls e a part of both
faces is cleaned, the cleaning action continuing only while the plate is still in the
grasp of the rolls a. When the plate is freed therefrom the cleaning action of
the rolls e ceases and the plate is carried forward by the rolls e and delivered to the
inclined guide by which it is directed to the lower feed rolls i set, as shown, at an
angle. The guide his so placed that the plate is thereby presented to the rolls i
with the uncleaned part leading. By the rolls the plate is fed to a second pair of
sheepskin-covered rolls k also set at an angle, as shown. In its passage between
the rolls k the previously uncleaned part of both faces of the plate cleaned as
above described with reference to the part first cleaned. The toothed gearing
through the medium of which the various rolls are rotated is so arranged and set
that the speed of the feed rolls a and i is the same, as is also the case, at a higher
rate, of the sheepskin-covered rolls e and k.
Between the bushes of the sheepskin-covered rolls are spiral springs m the tension
of which is controlled by the set screws n and the pressure exerted on the plates is
thus regulated.
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 :-
The improved machinery for cleaning tin and terne plates hereinbefore described
and shown in the accompanying drawing, that is to say in which the plates are in
succession presented by feed rolls such as a to rolls such as e and after having been
thus partially cleaned are through the medium of an inclined guide such as h

set but inclined or tilted towards the feeding end as shown.
