PROVISIONAL SPECIFICATION.
An Improved Machine for Cleaning, Rubbing, and Finishing Tin
Terne or any other Coated Plates.
JOHN HOPKINS Mechanical Engineer Station Road Llanelly. I do hereby
declare the nature of this invention to be as follows:
The invention consists in providing an improved machine consisting in the first
instance of a large drum revolving in a trough containing bran or other suitable
material to clean the plates. On the outside face of the drum are raised pieces onl
which are fixed series of clips or nippers to receive the plates as they drop (at a
suitable moment) from a box placed in front of the machine. Immediately the
plate drops the nippers actuated by a suitable arrangement closes and firmly grasp
the plate which is drawn (not shoved or otherwise forced) through the bran. On
the plate arriving at the other side of the drum the nippers are again actuated upon
and at a suitable moment open out and drop the plate on a table leading to a series
of rolls each pair alternately covered with india-rubber sheep-skin or asbestos or
other suitable material.

COMPLETE SPECIFICATION.
An Improved Machine for Cleaning, Rubbing, and Finishing Tin
Terne or any other Coated Plates.
JOHN HOPKINS Mechanical Engineer Station Road Llanelly. I 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:
My invention consists in providing an improved machine to clean tin terne or any
other coated plates with greater speed reduced labour and less cost.
The plate A to be operated upon is first placed by the boy in the box B.
By the revolving action of the drum C on which are fixed a series of tappet
brackets D coming in contact with the lever E pressing the same down opens the
two doors F and G thus allowing the plate to drop into the jaws of the clips or
nippers H which are fixed on raised pieces I secured to drum.
Immediately the plate drops into the clips the said clips are closed by the action
of the radial cam-ring acting through rods K and L. The cam-ring may be made
to any convenient diameter or equal to distance of L and L these rods would be
lengthened to work direct in groove of cam-ring and thus dispense with rods K.
The plate is thus firmly gripped by the clips and is drawn by the revolving
action of the drum through the bran or other suitable material which the pan or
trough M contains and is then thoroughly cleaned froin oil, grease &c.
When the plate arrives on opposite side of drum C the radial cam-ring J acts in
opposite direction and opens the clips H thus allowing the plate to drop on the
inclined table N leading to the finishing rolls.
The finishing rolls consists of a group of rolls O and P covered alternately with
india rubber sheep-skin or other suitable material-also of a pair of flying rolls Q
covered with sheep-skin or made in the form of a brush with fine hair or other
suitable material-revolving in opposite direction to clean the last pair of finishing
wool rolls.
The whole machine is carried and supported by two cast iron side cheeks R

of access.
The accompanying drawings will serve to show the whole improvements and
arrangements of various parts but I do not confine myself to the exact shape
size or proportions of parts shown as they may be varied increased or reduced.
Fig. 1 is a sectional elevation of machine.
Fig. 2 plan of machine.
Fig. 3 is another mode of grouping the rolls-whereby the plate as in Fig. 1 is
allowed to drop on inclined table N leading to the rolls-on leaving the top tier of
rolls the plate is again allowed to drop on inclined table S which returns the plate
to the rolls T to be again operated upon in reverse direction.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed-I declare that what I
claim is
:
First. The receiving box with its automatic gear for opening, both doors substan
tially as shown and for the purpose specified.
Second. The enclosed hollow drum with raised pieces substantially as shown and
for the purpose specified.
Third. The clips or nippers substantially as shown and for the purpose specified.
Fourth. The radial cam-ring and gear for opening and closin, the clips substan-
tially as shown and described and for the purpose specified.
Fifth. The flyers for cleaning the top and bottom of last pair of wool rolls
substantially as shown and for the purpose specified.
Together with the whole arrangements and application of the various parts and
movements to obtain the desired end.
