PROVISIONAL SPECIFICATION.
A Tin and Terne Plate Cleaning Machine.
I, EDWARD JONES, of Rhiwderin, near Newport, in the County of Monmouth,
Licensed Victualler and Timber Merchant, do hereby declare the nature of this
invention to be as follows:-
This invention consists in an arrangement of mechanism and apparatus constituting
an improved machine for cleaning tin and terne plates.
According to this invention the plates as they are taken from the grease pot of
the tinning bath are placed on a slide by which they are mechanically fed to a
chamber forming part of my improved apparatus and containing sawdust or other
substance such as is usually employed for cleaning tin and terne plates. The plates
are in succession drawn through the said chamber and the sawdust therein by a pair
of rollers coated with india-rubber. In their passage through the said chamber the
plates are rubbed by india-rubber vanes fixed to spindles rotating in the chamber
at a greater speed than the rate at which the plates travel. By the said india-
rubber vanes the sawdust is rubbed on both faces of the plates, and adhering
grease is in part removed. The plates are passed on to and seized between a
second pair of impelling rollers coated with india-rubber between which and the
first set of impelling rollers is a pair of dusting rollers having a coat of horse-hair
or like substance sufficiently stiff to brush the plates but not so rigid as to scratch
them. The roller brushes rotate with the plate which is passed on to a third set
of impelling rollers between which and the second set is a pair of roller brushes
similar to those above mentioned. The second set of roller brushes rotate against
the plate which passes between them and is delivered cleaned at the delivery end
of the machine by the third set of impelling rollers aforesaid.
The whole of the rollers are rotated by suitable gearing arranged at both sides
of the machine.

COMPLETE SPECIFICATION.
A Tin and Terne Plate Cleaning Machine.
I, EDWARD JONES, of Rhiwderin, near Newport, in the County of Monmouth,
Licensed Victualler and Timber Merchant, 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 an arrangement of mechanism and apparatus constituting
an improved machine for cleaning tin and terne plates.
According to this invention the plates as they are taken from the grease pot of
the tinning bath are placed on a slide by which they are mechanically fed to a
chamber forming part of my improved apparatus and containing sawdust or other
substance such as is usually employed for cleaning tin and terne plates. The
plates are in succession drawn through the said chamber and the sawdust therein
by a pair of rollers coated with india-rubber. In their passage through the said
chamber the plates are rubbed by india-rubber vanes fixed to spindles rotating in
the chamber at a greater speed than the rate at which the plates travel. By the
Baid india-rubber vanes the sawdust is rubbed on both faces of the plates, and
adhering grease is in part removed.

page_text: The plates are passed on to and seized between a second pair of impelling rollers
coated with india-rubber between which and the first set of impelling rollers is a
pair of dusting rollers having a coat of horse-hair or like substance sufficiently stiff
to brush the plates but not so rigid as to scratch them.
The roller brushes rotate with the plate which is passed on to a third set of
impelling rollers between which and the second set is a pair of roller brushes
similar to those above mentioned. The second set of roller brushes rotate against
the plate which passes between them and is delivered cleaned at the delivery end
of the machine by the third set of impelling rollers aforesaid.
The whole of the rollers are rotated by suitable gearing arranged at both sides
of the machine.
In the accompanying sheet of drawings, Fig. 1 represents a side elevation of my
improved apparatus for cleaning tin and terne plates. Fig. 2 is a transverse section
of the feeding slide and frame. Each plate as it comes from the grease pot of the
tinning bath is laid on the table a which, by operating the hand lever b connected
to the table by the link o and bracket d, is moved to the position shown, that is to
say, sufficiently far to enable the plate to be grasped by the first set of impelling
rolls e. When the plate has thus been grasped the table a is drawn back by the
balance weight to receive another plate.
Figs. 3, 4 and 5 represent respectively a front elevation, a vertical section and a
plan of the plate cleaning part of the apparatus. These figures, in which the
feeding slide is not shown, are drawn to a larger scale than Figs. 1 and 2. Each
plate is fed into the chamber which is charged with sawdust or other usual
cleansing substance. In this chamber 9 rotate a pair of spindles h fitted with
strips or vanes i of india-rubber. The plate as it is drawn through the chamber
h
by
the rolls e is rubbed on both sides by the vanes i which rub the sawdust against
the plate and thus remove adhering grease. The spindles or bodies à carrying the
vanes i are rotated at a greater speed than corresponds to the rate of progress of
the plate. Beyond the vanes i and between them and the rollse is a pair of guides k.
From the rolls the plates are directed by guides 1 to pass into the grasp of the
second set of impelling rolls m between which and the rolls e rotate a pair of roller
brushes n coated with horse-hair or like substance having hairs or bristles sufficiently
stiff to brush the plates but not so rigid as to scratch or mark them. The roller
brushes n rotate in the direction indicated by the arrows, Fig. 4. From the rolls m
the plates are passed between guides o and p to a third set of impelling rolls g
between which and the rolls m rotate a second pair of roller brushes r similar to
the roller-brushes n. The latter rotate in the direction indicated by the arrows,
Fig. 4, that is to say, against the line of progress of the plates. The plates after
passing between the roller-brushes are delivered in the cleansed state on to the
inclined tables by the rolls 9. Thence they are removed by an attendant.
The various rolls are driven by gearing situated as shown at both sides of the
frame which latter is preferably made in two parts hinged together as at t at the
delivery end so that the frame constitutes a box casing for the rolls.
At the bottom of the sawdust chamber g is an aperture for discharging the spent
sawdust. A slide u, Fig. 3, closes the aperture.
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
claim is :-
1. In a tin and terne plate cleaning machine, the provision of a chamber such
as g for containing sawdust or other cleansing medium, in which chamber are
arranged to rotate spindles or roller bodies such as h carrying india-rubber vanes
such as i, the said spindles being so set as to rub both faces of the plates as they
are drawn between them and to rub the sawdust or other cleaning substance against
the plates, as hereinbefore described with reference to the accompanying sheets of
drawings.
2. The roller brushes n and r covered with horse-hair or other substance having

page_text: bristles or hairs sufficiently stiff to remove the sawdust from the plates passed
between the said brushes, but not so rigid as to scratch or mark the plates, the first
set of such roller brushes, n, being arranged to rotate with the plates and the
second, r, to rotate against the line of progress of the plate, as hereinbefore
described with special reference to Fig. 4 of the accompanying drawings.
3. The sliding table a fitted in a suitable frame and arranged to move forward
towards the cleaning machine by actuating the hand lever 6 and to be drawn back
by the counterweight f, as hereinbefore described with reference to Figs. 1 and 2
of the drawings.
4. The combination of parts constituting the improved machine for cleaning tin
and terne plates, constructed, arranged and operating substantially as hereinbefore
described with reference to the accompanying sheets of illustrative drawings.
Dated this 9th day of August 1892.
