PROVISIONAL SPECIFICATION.
A Machine for Cleaning Tin and Terne Plates.
I, ARTHUR JAMES MASKREY of Lion Tin-plate Works, Nantyglo, in the county of
Monmouth, manager of Tin-plate Works, do hereby declare the nature of this invention
to be as follows:-
This invention consists in a machine for "dipping" tin and terne plates, that is to
say, for passing them through bran or like material, whereby the grease adhering to
the surfaces after passing through the grease-pot is absorbed.
Centred on a shaft extending across a trough in which the bran is contained are a
pair of skeleton discs adjustable towards or away from one another on the shaft.
The skeleton discs have radial arms towards the end of each of which is a rod
secured at one end to the radial arm, the other end being free and terminating in a
hook or bend. These hooked arms are disposed at a right angle to the arms to
which they are attached. At one end of the trough-that at which the plates are
fed are a pair of supports through apertures in which project the free ends of
springs which at the other ends are bolted to the supports. Attached to each arm
of one of the discs is a curved striker.
Each plate as it is taken from the grease pot of the tinning machine is laid on the
supports and rests on the ends of the springs projecting, as aforesaid, through the
supports.
When, in the revolution of the discs, each striker is presented at the feeding end
of the trough, it is brought into contact with a lever on which are two cranks which
are forced against the springs aforesaid. By this means the free ends of the springs
are withdrawn from below the plate. The striker now having passed the lever, the
springs resume their normal position behind the plate.
On the outside of each arm of each disc is a bar which at the rear end is by a

front this bar, which may be, conveniently called a clip, is shaped as a hook.
Immediately after the free ends of the springs are withdrawn from below the
plate, as aforesaid, the pivotted tappets of each of the arms then presented opposite
the plate come into contact with rods or arms fixed to the trough. The tappets are
thus caused to turn on their pivots and the resistance of the springs attached to the
clips aforesaid is overcome and the ends of the hooks of the clips, previously in
contact with the extremities of the radial arms, are forced outwards to receive the
plate as it falls. When the tappet has passed clear of the rods or arms fixed to the
trough the springs of the clips again come into action and the plate is gripped between
the ends of the hooks of the clips and the outer extremities of the radial arms of the
skeleton discs which, continuing to revolve, carry the plate through the bran
contained in the trough for the absorption of the grease.

COMPLETE SPECIFICATION.
A Machine for Cleaning Tin and Terne Plates.
I, ARTHUR JAMES MASKREY, of Lion Tin-plate Works, Nantyglo, in the county of
Monmouth, manager of Tin-plate Works, 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 a machine for "dipping" tin and terne plates, that is
877

page_text: to say, for passing them through bran or like material, whereby the grease adhering
to the surfaces after passing through the grease-pot is absorbed.
Centred on a shaft extending across a trough in which the bran is contained are a
pair of skeleton discs adjustable towards or away from one another on the shaft.
The skeleton discs have radial arms towards the end of each of which is a rod
secured at one end to the radial arm, the other end being free and terminating in a
hook or bend.
These hooked arms are disposed at a right angle to the arms to which they are
attached. At one end of the trough-that at which the plates are fed-are a pair
of supports through apertures in which project the free ends of springs which at
the other ends are bolted to the supports. Attached to each arm of one of the discs
is a curved striker.
Each plate às it is taken from the grease pot of the tinning machine is laid on
the supports and rests on the ends of the springs projecting, as aforesaid, through the
supports.
When, in the revolution of the discs, each striker is presented at the feeding end
of the trough, it is brought into contact with a lever on which are two cranks which
are forced against the springs aforesaid. By this means the free ends of the springs
are withdrawn from below the plate. The striker now having passed the lever, the
springs resume their normal position behind the plate.
On the outside of each arin of each disc is a bar which at the rear end is, by a
spring, normally held against the lower end of a tappet pivotted on the arm.
At the front this bar, which may be conveniently called a clip, is shaped as a hook.
Immediately after the free ends of the springs are withdrawn from below the
plate, as aforesaid, the pivotted tappets of each of the arms then presented opposite
the plate come into contact with rods or arms fixed to the trough. The tappets are
thus caused to turn on their pivots and the resistance of the springs attached to the
clips aforesaid is overcome and the ends of the hooks of the clips, previously in
contact with the extremities of the radial arms, are forced outwards to receive the
plate as it falls. When the tappet has passed clear of the rods or arms fixed to the
trough, the springs of the clips again come into action and the plate is gripped
between the ends of the hooks of the clips and the outer extremities of the radial
arms of the skeleton discs which, continuing to revolve, carry the plate through the
bran contained in the trough for the absorption of the grease.
Referring to the accompanying drawings, Fig. 1 thereon represents a plan and
Fig. 2 a side elevation of my improved machine for cleaning tin and terne plates.
Centred on the shaft a extending across the trough in which the bran is con-
tained are a pair of skeleton discs c c adjustable on the shaft and having projecting
arms d d fitted with mechanism for assisting to feed the plates and for conveying
them through the bran.
This mechanism is represented in the drawing as applied to one arm only of each
disc, but it is to be understood that precisely similar mechanism is applied to the
other arins.
It consists of a hooked rod e fixed to the arm, a hooked bar g, spring h
and a tappet. The arms d of the disc c each carry, in addition, a curved striker f.
The
The hooked barg is secured to the arm by pins m passed through slots n.
spring his attached to the rear end of the bar y and to the arm. The tappet is
pivotted on the arm.
P
The plates to be cleaned in the machine are each laid in turn against the supports o
fixed at the feeding end of the trough. One end of the plate rests upon the free
ends of the springs p bolted at the other ends to the supports. Carried in bearings
secured at the back of the supports is a lever g on which are formed the two cranks q
When, in the revolution of the discs, through the shaft a and pulley a', the curved strikerf
of each arm of the disc c comes into contact with the lever g, the cranks force back
the springs and the plate, being no longer supported thereby, drops. Immediately
thereafter the front face of each of the tappets i is brought into contact with the
rods fixed at each side of the trough b. The tappets are thereby tilted on their
pivots and the springs being thus overcome, the hooked bars g are forced outwards.

page_text: The
The plate is received in the hooks and as soon as the tappets resume their normal
position, the bars are drawn back and the plate is gripped between the points of
the hooks and the outer ends of the projecting arms of the skeleton discs.
hooked arms or guides e assist to keep the plate in proper position as it is carried
round through the bran to the delivery tables at the other end where the tappets i
coming into contact with the short arms projecting inwards from both sides of the
trough cause the hooked bars
to be projected outwards from contact with the plate
which is then released.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The use, for cleaning tin and terne plates, of a trough or troughs such as b
having discs c, c rotating therein, such discs being furnished with projecting
arms d, d fitted with guides e, hooked bars g, springs h and tappets i, arranged and
operating to carry the plates through the bran in the trough, substantially as herein-
before described.
2. The means for holding and foeding the plates to the trough, consisting of the
supports o, springs », lever q with cranks g, and the curved strikers f for actuating
the said levers and springs, substantially as herein before described.
3. The provision of the short arms at the delivery end of the trough arranged
for actuating the tappets and hooked bars g for release of the plates after cleansing,
substantially as herein before described.
4. The combination of parts constituting the improved machine for cleaning tin
and terne plates, constructed, arranged and operating substantially as herein before
described and for the purposes specified.
