COMPLETE SPECIFICATION.
Improvements in Machinery for Bronzing, Colouring, and similarly
Ornamenting Paper or other material in Sheets or Continuous
Rolls.
I JOHN BROMLEY of Belinda Street Hunslet Leeds in the County of York
Mechanical 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 :-
My invention refers to that class of bronzing colouring and ornamenting
machines (hereinafter for the sake of brevity referred to as bronzing machines)
described in the Specification of Letters Patent No. 5596 of 1887 and more
particularly to means for distributing the bronze or other powder in a uniform
manner over the sheet of paper or other material.
1.
For this purpose I provide in such machines a trough or box in which the
powder is placed ready for distribution on to the sheet or roll of paper or other
material. At the bottom of this box is a revolving delivery brush or roller
which feeds the powder from the box. In order to render more uniform the
delivery of the powder, I provide a laterally reciprocating brush which moves to
and fro across the exposed part of the delivery brush or roller. The laterally
reciprocating brush may be flat, and have only a laterally reciprocating motion.
Or this brush may be circular and have a rotary motion instead of the recipro-
cating motion, or in addition to the reciprocating motion. The laterally
reciprocating motion may be imparted to this brush by means of a cam or crank,
either directly, or by means of intermediate levers, links, or connecting rods.
The lateral motion may be positive, i.e. moved in both directions by the above
mechanism, or as I prefer the return movement may be effected by a spring or
springs or weight.
A mechanically equivalent arrangement of my invention would be to keep the
brush, (above designated as the laterally reciprocating brush,) stationary; and to
impart a laterally reciprocating motion to the revolving delivery brush at the
bottom of the box.
And in order that my invention and the nanner in which the same is to be
performed may be more readily understood, reference is given below to the
accompanying drawings, which are a reproduction of the drawings accompanying
the Specification of my former Letters Patent No. 5596 of 1887, and I have in
the present drawings retained the same reference letters.
Reference is given in the following description, only to such parts of the
machine as comprise or are more immediately connected with this my present
invention.
Figs. 1 and 2 are respectively cross sectional, and end elevations, and Fig. 3 is a
part side elevation, of a machine constructed according to my present invention.
b is the box containing the bronze or other powder.
J is the revolving delivery brush or roller.
1 is the laterally reciprocating brush, shewn in the drawings as a flat brush.
The lateral reciprocating motion is imparted to the brush 1 by means of the
hinged lever 2, the lower end of which catches against the upturned end 3 of the
shaft of the brush 1. The lever 2 is moved in one direction by means of
the revolving cam 4, and is moved in the opposite direction and kept pressed
against the cam by means of the spring 5 at the opposite end of the shaft 1.
The cam 4 is keyed on the shaft O.
The brush J is rotated by means of the worm N on the shaft O, worm wheel 6,
and gear wheels 7 and M; the latter being keyed on the end of the shaft of the
brush J.

page_text: When the brush 1 is circular, the rotation of the same may be effected by means
of gear wheels on the shafts of the brushes J and 1, with intermediate gear wheel
or wheels to obtain the proper direction of rotation for the brush 1.
If the brush 1 is kept stationary, the lateral reciprocating motion may be
imparted to the brush J by the cam 4 and hinged lever 2 in the manner above
described, but provision must be made by a sliding feather or key arrangement to
permit of the simultaneous rotation of the brush J."
I wish it to be understood that I do not limit myself to the arrangements just
above described and illustrated for imparting a lateral reciprocating movement to.
the brush 1 (or J), nor to the means for imparting a rotary motion to the same,
these being merely given as an illustration of the manner in which my invention
may be performed, but
Having now particularly described and ascertained the nature of my said inven-
tion and the manner in which the same is to be performed, I declare that what
I claim is :-
1° In bronzing and similar ornamenting machines the use and arrangement of a
laterally reciprocating brush moving across the exposed face of the powder delivery
brush or roller for the purpose of causing a more uniform delivery of the powder
substantially as herein set forth.
2° In bronzing and similar ornamenting machines the combination of a delivery
box, a rotating delivery brush or roller discharging powder from the box and a
laterally reciprocating brush (or a rotating brush rotating in the opposite direction)
moving in contact with the former substantially as and for the purposes herein set
forth.
3° In bronzing and similar ornamenting machines the combination of the powder
box b, delivery brush or roller J rotating without (or with) a simultaneous laterally
reciprocating motion, the brush 1 having a laterally reciprocating motion or a
circular motion (or fixed) and the mechanism for imparting the laterally recipro-
cating motion to the same substantially as herein set forth.

improved bronzing and ornamenting machine substantially as herein set forth and
illustrated in the accompanying drawings.
