engineer, do hereby declare the nature of this invention to be as follows-
"This invention relates to cleaning tin and terne plates after they are delivered
from the coating pot. It consists, firstly, in the employment of a pair of cleaning
tionghs arranged one behind the other, and containing the "bian" or other suitable
cleansing substance for cleaning the plates.

the bran to the opposite end of the trough, guides being fitted in the trough to
ensure the proper passage of the plates

brackets pivotted on a shaft extending transversely across the trough. These
brackets are tilted by the forked arms and the plates are thereby tuined over and
received by the forked aims in the back trough through the bian in which they are
passed reversed.

delivery-table by means of brackets similar to those above mentioned as used for
transferring the plates from the forked arms of the front trough to those of the back
trough

passage through the cleaning troughs, and for mechanically feeding the plates to the
forked arms. The rack is composed of a convenient number of spokes or arms
springing from a central boss in the same manner as the spokes of a wheel. The
plates as they are taken from the bath of coating metal are laid on the arms of the
rack which is centred on a transverse shaft towards one end of which is a recessed
boss in the recesses of which bears a flat spring tending to keep the rack stationary.

Improvements in Machinery or Apparatus for Cleaning Tin and
Terne Plates.
I, JAMES ABBOTT, of Chapel Teriace, 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 operation of cleaning tin and terne plates by dipping
the same in " bran or other cleansing substance for the purpose of removing the
grease adhering to them after delivery from the grease pot
It consists, firstly, in the employment of a pair of cleaning troughs placed one
behind the other and containing the bran by the passage through which of the plates
the latter are cleansed. Each trough is provided with forked arms centred on a
shaft extending transversely across the trough and rotated by bevel or other gearing,
or by other mean-.
The plates are fed into the front trough at the front end thereof
They are placed
in the forks of the arms and are thereby carried round through the bran to the
opposite end of the dough, guides being fixed in the trough to ensure the proper
passage of the plates
On arriving at the rear end of the front trough the forked arms engage with
biachets carried on a spindle extending transversely across the trough. These
brackets are tilted by the forked arms and the plates are thereby dislodged and are
received into the forks of the arms in the second trough through the bran m which
the plates are passed having that face uppermost which in the fist trough was undermost.
On arriving at the rear end of the back trough the plates are tilted on to the
delivery table by means of brackets similar to those above mentioned as used for trans-
ferring the plates from the forked arms of the front trough to those of the back trongh.
By passing the plates through two troughs in the manner described the plates are
mechanically cleansed uniformly on each face.
This invention consists, secondly, in a rack for holding the plates prior to then
passage through the cleaning troughs, and for mechanically feeding the plates to the
forked arme
The rack is composed of a convenient number of spokes or arms
springing from a central boss in the same manner as the spokes of a wheel.
The plates as they are taken from the bath of coating metal are laid on the arms
of the ack which is centred on a transverse shaft towards one end of which is a
recessed boss in the recesses of which bears a flat spring tending to keep the rack
stationary. The forked arms of the front trough are provided on the outside with
projections which, as the arms rotate, strike other prejections formed at the ends of
short aims connected with the rack.
The resistance of the spring is thereby overcome and the rack is rotated to a given
extent, the spring acting as a brake by taking into the next recess of the boss
and preventing further rotation.
The plates are in succession thus carried down and, are received into the forked
arns of the first cleaning trough.
This invention further consists in means for finishing the operation of cleaning the
plates as they emerge from the back trough.
Arranged at a suitable distance apart on a table at the delivery end of the back
trough are two pairs of rollers having their axes set transversely, that is to say,

page_text: arallel with the shafts on which the forked arms of the cleaning troughs are carried.
a the space between the pairs of rollers are a pair of endless bands which are passed
round rollers fitted at each side of the table The bands, which travel in contrary
rections, extend transversely across the table, one band being arranged above the
her The plates coming from the back cleaning trough are passed in succession
etween the two pairs of rollers first aforesaid and in their transit from one pair
the other they pass between the bands and are thereby further cleaned on both
ces
Fig 1 is a plan and Fig 2 a side elevation of my improved machinery or apparatus
for cleaning tip and terne plates a and a¹ are two cleaning troughs for containing
the bran or other substance employed for absorbing the grease adhering to tin and
terne plates after they emerge from the grease pot. The troughs are placed in line,
one belund the other, as shown.
On the shaft b extending across the trough a and carried in bearings at each side
thereof are centred forked arms c.
Similar forked arms
are centred upon the shaft
extending across the
trough a¹.
The shafts with the arms c care rotated by bevel or other gearing or by
other means.
The plates are deposited in the forks of the arms c of the trough a as
they, the forks, are presented in rotation at the front or feeding end of the trough a.
The plates are thereby carried round through the bian to the opposite end of the
trough Guides, d-see Fig 1-are fixed in the trough to keep the plates in place
at starting
On arriving at the back end of the trough a the arms c come into contact with
the brackets e consisting of curved plates recessed or cut away at the middle, as
shown, and fixed on the spindle f free to turn in bearings at each side of the
trough
These brackets e are struck and tilted by the arms c as the latter rotate and,
coming into contact with the plate, the brackets dislodge the plate from the fork and
so cause it to he transferred to a fork of the arms c₁ of the trough a through the
bran in which the plate is then passed having that face uppermost which was under-
most in passing through the trough a
When the plate reaches the delivery end of the trough a¹ it is transferred to the
delivery table g by the brackets e¹ on the spindle f' in the same manner as that in
which the plate is transferred from the trough a to the trough a¹ By passing the
plates through two troughs in succession and with reversed faces, as above described,
they are cleansed mechanically on each face more uniformly than heretofore.
This invention consists, secondly in an improved rack for holding the plates prior
to their passage through the cleaning troughs and for mechanically feeding the plates
to the forked arms. The rack is composed of a convenient number of spokes or
arms springing from a central barrel i, as shown, and contained between two side
discs k and the former of which is furnished with short arms m bent outwards at the
outer ends to form projections. The plates to be cleaned are laid on the arms h of
the rack which is centred on the transverse spindle n towards one end of which is a
recessed boss o having a flat spring p bearing against it and tending to keep the rack
stationary.
As the forked arms c rotate, the projections s provided on the outside thereof strike
in turn the short arms m of the rack and rotate the latter causing the regular
transfer of the plates to the forks of the arms c The spring p acts as a stop to the
rack preventing it from rotating at one time more than to the extent of one recess
of the boss o
My invention further consists in improved means for finishing the operation of
cleaning the plates as they emerge from the second trough.
This operation is known as dusting.

page_text: Arranged at a suitable distance apart on a tablet at the delivery end of the
trough a are two pairs of rolls u u¹ disposed transversely. Between these sets of rolls
1s a pair of endless bands w to¹ of canvas or other suitable substance travelling
transversely each in opposite direction across the table t around rollers v arranged at
each side thereof. The plates are conducted by the inclined delivery table
rolls u and fed thence to the rolls u and in their transit from the rolls u to the
rolls they pass between the bands w w¹ by which they are dusted or finally cleansed
to the
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 the operation of dipping or cleaning tin and terne plates, the employment,
for containing the "bran or other cleansing medium, of two troughs placed
adjacent to one another through both of which the plates are passed in succession,
having that face uppermost in their passage through the second trough which i
their passage through the first was undermos:, substantially as her einbefore
described
2 The forked arms c. c¹ for conveying the plates through the troughs a, a', and,
carried on shafts, rotating with the said arms substantially as described.
3. The brackets e el, carried on spindles 1, ³, for transferring the plates from the
forked arms c to the forked arms and from the latter to the delivery table
respectively, substantially as herembefore described
4 In combination with the cleaning trough a. the rack for bolding the plates and
for mechanically feeding the same in succession to the forked arms c of the said
tough, substantially as and by the means herein before described
5 In combination with the cleaning trough a¹ the transverse rolls u and u¹ and
the endless bands w¹ for dusting or finally cleaning the plates, substantially as
described
