PROVISIONAL SPECIFICATION.
Improvements in Machinery or Apparatus for Cleaning Tin and
Terne Plates.
I, JAMES ABBOTT, of Chapel Terrace, Blaina, in the county of Monmouth,
engineer, do hereby declare the nature of this invention to be as follows:-
This invention, which relates to cleaning tin and terne plates after they are taken
from the grease pot, consists, firstly, in an arrangement of rollers and troughs whereby
the plates are cleansed on both sides while vertically disposed.
On being taken from the grease pot, each plate is inserted, either by hand or
mechanically, between a pair of feed rollers by which it is fed in a-vertical position
into a trough above containing the "bran" or other suitable cleansing medium
Rotating in the cleaning trough are cleaners between which the plate passes. The
cleaners, which rotate at a higher speed than the feed rollers, may consist of rollers
clothed with sheepskin, or they may consist of arms radiating from a central boss.
By the cleaners the bran is raised and brought to bear against both faces of the
plate as it passes vertically through the trough.
Above the cleaning trough are a second pair of feed rollers by which the plate is
withdrawn from the trough and is delivered to a pair of dusting rollers of the usual
kindl It is thereby freed from any adhering bran. It is then passed through a
pair of delivery rolls on to a table
Above the cleaning trough aforesaid and between it and the dusting rollers may
be placed a second cleaning trough having cleaners, as above described.
This invention further consists in means for mechanically feeding the plates to the
first pair of feed rollers. Travelling around pullies or drums are a pair of endless
chains upon which the plates are conveyed from the grease pot to the feed rollers.
The plates rest at one end against brackets or stops provided therefor on the chains.
They are guided to the feed rollers by suitable guides.

COMPLETE SPECIFICATION.
Improvements in Machinery or Apparatus for Cleaning Tin and
Terne Plates.
I, JAMES ABBOTT, of Chapel Terrace, Blaina, in the county of Monmouth,
engineer, 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 relates to the cleansing of tin and terne plates after they are
delivered from the metal bath and grease pot.
According to this invention each plate on being taken from the grease pot is
inserted between a pair of rollers by which, as they rotate, it is fed to a cleaning
trough situated immediately above the said rollers and containing bran or other
substance usually employed in cleaning such plates Rotating in the cleaning trough
are cleaners consisting of arms or brushes radiating from a central shaft or boss.
By the cleaners, which rotate at a higher speed than the feed rollers aforesaid, the
bran is carried up against both sides of the plate as it passes vertically upwards.

page_text: From the cleaners the plate is fed by a second pair of feed rollers to cleaners situated
above, whereby the plate is again rubbed with bian.
Thence the plate passes upwards to "dusting" rollers to be freed from any adhering
bran. Above the dusting rollers is a pair of rollers for discharging the plates in the
cleansed condition
This invention consists, further, in means for mechanically feeding the plates to the
first pair of feeding rollers of the cleaning machine.
Travelling around pullies or drums are a pair of endless chains upon which the
plates are conveyed to the cleaning machine By means of guides the plates are
directed between the first pair of feed rollers
In the accompanying drawings, Fig 1 represents an end view and Fig. 2 a front
view of my improved arrangement of machinery and apparatus for cleansing tin and
terne plates. My improved means for mechanically feeding the plates to the cleansing
machinery is also illustrated in the said views
The plates may, however, be placed in the cleaning machine by hand.
As each plate is received from the grease pot of the tinning bath it is inserted
between the feed rollers a, a which are rotated by suitable gearing.
By the rollers a, a the plate is fed to the trough containing bran for cleaning.
Rotating in the trough 6 are cleaners c c consisting of arms or brushes extending
as spokes from central shafts or bosses By the cleaners the bran is carried up and
pressed against both sides of the plate which is thereby cleansed as it passes, while
vertical, upwards between the cleaners. Instead of being composed of arms or
spokes, as shown, the cleaners may consist of drums or skeleton drums clothed with
sheepskin or the like.
Similarly, by the feed rollers a¹ a¹ the plate is fed further upward to a second set
of cleaners c¹ c¹ rotating in a second cleaning trough 6¹, and thus subjected to further
cleansing.
Above the trough b' is a pair of rollers d, d by which the plates are carried up to
be seized between the "dusting" rollers e e by which any adhering bran is removed.
Thence the plates are delivered from the machine in the cleansed state by the delivery
rolls ff at the top of the machine. In some cases the plates may be passed through
one set of cleaners only and be delivered thence to the feed rollers which conduct
them to the dusting rollers.
The means whereby the plates are fed from the grease pot of the tinning bath to
the feed rollers a a consist of a pair of endless chains or jointed bars z arranged
around guide pullies k k².
Hinged on the chains are fingers which serve as rests for the ends of the
plates laid on the chains On arriving at the rollers a a of the cleansing machine
the plates are directed between the rollers by the guides m m fixed to the frame of
the machine. By the fingers on which they rest the plates are forced up to the
rollers a a between which they are gripped and so drawn up and passed into the
cleaning trough above, the chains being returned over the pullies k¹. n is a guide
for use when the plates are fed to the rollers a, a by hand.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
clann 15.
1 Cleaning tin and terne plates by passing the same, after delivery from the
grease pot of the tinning bath, through a pair of feed rollers to a trough situated
immediately above the rollers and containing bran or other cleaning substance, the
said trough being fitted with rotating cleaners such as cc, or their equivalents, thence
passing the plates by feed rollers, either directly to dusting rolls situated next above
the trough, or through a second cleaning trough similar to the first and thence to
dusting rolls, substantially as herein before described.

page_text: 2. The means hereinbefore described for mechanically feeding the plates to the
feed rollers of the cleaning machine, said means consisting of endless jointed bands
or chains such as fitted with fingers such as 7 and arranged to travel round pulleys
in such manner as to convey the plates to the feed rollers of the cleaning machine,
as hereinbefore set forth.
