page_text: I THOMAS GREAVES, of Southbrooke Road Works, Lee, in the county of Kent,
Manufacturer 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 relates to the construction of an improved bronzing and polishing
pad for applying bronze or like metallic powder to printed engraved or like surfaces
and for subsequently polishing such surfaces so treated.
I have in the accompanying drawings shewn in Figure 1 a plan of my improved
pad the lid of the bronzing box being shewn removed. In Figure 2 I shew a
transverse vertical section of the same on line a b. A is a box of suitable size and
capacity and advantageously formed with hopper like sides as clearly shewn and
which box when filled with the bronzing or metallic or like dusting powder is closed
by a lid B which may slide in grooves in the box or be shut over it.
The bottom of the hopper like part of the box is covered by a plate C in which a
longitudinal slot D is formed. The hopper mouth itself is covered by a plate of
perforated metal E rigidly fixed to the box bottom. The bottom of the box has a
beaver or other fur or soft lining F applied to same as usual in bronzing pads.
On the plate C I arrange a plate G to slide to and fro so as to cover and uncover
the slot D accordingly as more or less powder has to be delivered.
To adjust this plate G I provide a lug or boss H carried thereon in which turns the
smooth end of a screwed pin I, the screwed part working in a boss or collar J fixed in
the side of the box, and the screwed pin being turned by hand wheel or nut K. On
rotating the screwed pin I the plate G can come more or less over the slot D in the
plate C, and so allow more or less powder placed in the body of the box Å to escape
from the hopper mouth to the perforated metal plate E and from thence to the surface
to be operated upon.
To enable bronzing pads to be used also as polishing tools I combine with such
pads a polisher of felt or other suitable material such as L provided on the side or
sides or end or ends thereof. By this means I provide a combined tool for bronzing
or applying powder and polishing or burnishing the work.
I am well aware that bronzing pads having a slotted slide covering slots in a plate
over the perforated delivery plate, such slide being moved longitudinally in relation to

page_text: the body of the pad; are in use and I do not claim such, but, by my invention I
ensure a much more even distribution of the bronze or other powder as the use of the
open slot D and the sliding plate G ensures this.
Furthermore the adjusting screw being at the side of the pad is very convenient to
handle.
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 :-
First: The improved construction of bronzing and polishing pad substantially as
described and illustrated in the accompanying drawings.
Second-In a pad for applying bronze or like powder to printed engraved or like
surfaces the combination of a body or box A, plate C having longitudinal slot D,land
sliding plate G moved over the same, and operated by a screw at right angles to the
axis of the said slot substantially as described.
Third In combination with a pad for applying bronze or like powder to printed
engraved or like surfaces, a polishing device such as L substantially as described.
Dated this 24th day of March 1888.
