page_text: LETTERS PATENT to William Elmore, of 91, Blackfriars Road, in the County
of Surrey, Electric Engineer, for an Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF SHEET METAL PLATES, AND IN APPARATUS THEREFOR."
(Void by reason of the Patentee having neglected to file a Specification in
pursuance of the conditions of the Letters Patent.)
PROVISIONAL SPECIFICATION left by the said William Elmore at the Office
of the Commissioners of Patents on the 10th August 1880.
WILLIAM ELMORE, of 91, Blackfriars Road, in the County of Surrey, Electric
Engineer. "IMPROVEMENTS IN THE MANUFACTURE OF SHEET METAL PLATES, AND
IN APPARATUS THEREFOR.'
"
In the manufacture of tin, zinc, and other metal plates by the electro deposition
of tin, zinc, and other metals from their solutions upon plates of sheet iron or
steel difficulty has been experienced in producing an uniformly bright surface upon
such electrically coated plates, and the object of this Invention is to obviate this
difficulty by mechanical means, which I will now proceed to describe.
Upon standards and in bearings thereon is mounted a shaft, fitted in the middle
of its length with fast and loose pulley, and the ends of the shaft is collared and
screwed and provided with adjustable collar plate for purpose of securing upon the
shaft between the said collars cotton dollies or brushes for polishing or scratch-
brushing the surfaces of the plates to be operated upon. On the said standards in
a rearward position are provided other bearings for carrying a second cross shaft
carrying the band wheel for driving the polishing shaft, these said bearings being
one with the casting, and arranged so as that the driving band wheel will be out
of the vertical plane of the polishing shaft.
In combination with this polishing or scratch brushing device there is employed
in this mechanical process of polishing such plates as aforesaid a table mounted
upon a standard, the head whereof is capable of a compound action vertically by
means of hand wheel and screw, and sideways and end wise by handles and racks,
and pinions and slides, so as to bring the table which will carry the metal sheets
in any desired position under the cotton dollies or brushes.

page_text: In the initiatory preparing of the plates various compositions are employed, and
although preference is given to one on account of the very superior result obtained
from its use no description is here given, as it forms no part of the claim under
this Patent.
"
By using a wider or narrow size of "dolly" or brush a larger or smaller sized
plate can be polished, or sections thereof, even to the full size of the adjustable
table. In practice the dolly or brush is preferred to be of the full width of the
plates being treated, in which case the plates are laid on to the table, and the
pinion of the end wise movement thereof is actuated, and the plate is passed
underneath and in contact with the polishing surface of the "dolly' or brush,
which should be rotating at about 2000 revolutions per minute. The passage of
the plate against the "dolly or brush will take from one to three minutes,
according to the conditions of extent of surface operated upon, size of "dolly" or
brush, speed of rotation, and power employed, and is applicable for polishing Hat
surfaces of any kind of metal, large or small, and for treatment of irregular pieces
the table will be made with adjustable jaws for holding same.
