to the Surface of Paper or other Material.
I, WILLIAM BREWER SILVERLOCK, of Blackfriars Road in the County of Surrey,
Printer, do hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus used for applying bronze or other powder to
designs prepared upon the surface of paper or other material. It is applicablo more
especially to the apparatus for which I obtained Letters Patent dated June 20th
A.D. 1885 and numbered 7547, and also to that for which I have applied for Letters
Patent by application dated March 28th A.D. 1887 and numbered 4627, but it may
also be applied to other machinery or apparatus used for the like purposes.
In such machines or apparatus it is usual to employ a roller covered with a suitable
material, which is made to revolve in a trough or vessel containing the bronze or
other powder, so that as the roller revolves it takes up some of the powder and
transfers it to the surface of the paper or other material to which it is to be applied.
The paper is then made to pass over one or more similar rollers which not only have
a revolving motion, but also an endlong movement backward and forward, by which
the bronze or other powder is rubbed and made to adhere to the design upon the
paper or other material.
The latter then passes over or against one or more revolving rollers, or pads, by
which any surplus powder is removed from its surface.
By my present invention, I do not use an oscillating revolving roller for the
purpose of rubbing the powder upon the design as described, but instead I use a
bar extending across the paper or other material, and covered with a soft material
(such as sheepskin,) similar to that with which the rubbing rollers are ordinarily
covered, such bar having an oscillating movement backward and forward com-
municated to it.
I arrange the bar, which may be of wood or other suitable material, so that it is
supported near its ends in guides upon the sides of the box which contains the
bronzing rollers, so that it can move longitudinally backward and forward in the
guides. The surface of the bar next the paper may be provided with a metal or other

"
plate to which is attached the sheepskin or other soft material which is to be rubbed
against the paper as described, or the bar itself may be covered with such material.
At one end of the bar I arrange a projecting arin or stud, which may he provided
with a friction roller, and this stud enters a properly shaped groove or
campath
on the surface of a cylinder so that as the cylinder revolves the bar is driven back-
ward and forward in the direction of its length. The cylinder may be fixed upon the
axle of one of the bronzing or cleaning cylinders, which is driven in the way described
and shewn in the specification of my former Letters Patent already referred to, or
it may be driven in any other convenient way. Or, instead of a cylinder and
campath, a crank or cam may be used for the purpose of giving the backward and
forward movement to the bar.
One or more bars arranged and operating as described may be used, together with
or in place of revolving cylinders.
By the improved method of construction and arrangement described, the apparatus
is made more simple, cheap, and effective, and occupies less room, than in machines
as heretofore used."
It may be applied to machines in which the paper or other material passes over the
surface of one or more cylinders, or where it passes over flat tables.

to the Surface of Paper or other Material.
I, WILLIAM BREWER SILVERLOCK, of Blackfriars Road, in the County of Surrey,
Printer, 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, and accompanying drawing, (that is to say):
:-
This invention relates to apparatus used for applying bronze or other powder to
designs prepared upon the surface of paper or other material. It is applicable more
especially to the apparatus for which I obtained Letters Patent dated June 20th
A.D. 1885 and numbered 7547, and also to that for which I have applied for Letters
Patent by Application dated March 28th A.D. 1887, and numbered 4627, but it may
also be applied to other machinery or apparatus used for the like purposes.
In such machines or apparatus it is usual to employ a roller covered with a suitable
material, which is made to revolve in a trough or vessel containing the bronze or
other powder, so that as the roller revolves it takes up some of the powder and
transfers it to the surface of the paper or other material to which it is to be applied.
The paper is then made to pass over one or more similar rollers which not only
have a revolving motion, but also an endlong movement backward and forward, by
which the bronze or other powder is rubbed and made to adhere to the design upon
the paper or other material.
The latter then passes over or against one or more revolving rollers, or pads, by
which any surplus powder is removed from its surface.
By my present invention, I do not use an oscillating revolving roller exclusively,
for the purpose of rubbing the powder upon the design as described, but I use a bar
as illustrated in the accompanying drawing, in which figure 1 is an end view in
section, and figure 2 a plan of the improved arrangement. a is a bar extending
across the paper or other material, and covered with a soft material a¹ (such as sheep-
skin) similar to that with which the rubbing rollers are ordinarily covered. The bar a
which may be of wood or other suitable material is supported near its ends in guides
at b, b, upon the sides of the box e which contains the bronzing rollers, so that it can
move longitudinally backward and forward in the guides. The surface of the bar a
next the paper may be provided with a metal or other plate (as shewn) to which is
attached the sheepskin or other soft material a', which is to be rubbed against the
paper as described, or the bar itself may be covered with such material.
At one end of the bar a I arrange a projecting arm or stud c, which may preferably
be provided with a friction roller, and this stud enters a properly shaped groove or
campath" on the surface of a cylinder d so that as the cylinder revolves, the bar is
driven backward and forward in the direction of its length so that its soft surface a¹
rubs the paper or other material which is being bronzed.

page_text: The cylinder d may be fixed upon the axle of one of the bronzing or cleaning
cylinders, which is driven in the way described and shewn in the specification of my
former letters Patent already referred to, or it may be driven in any other convenient
way. Or, instead of a cylinder and campath, a crank or cam may be used for the
purpose of giving the backward and forward movement to the bar.
represents the roller by which the bronze or other powder is supplied to the
surface of the paper, and s is a roller by which any surplus powder is removed from
the paper.
One or more bars arranged and operating as described may be used, together with
or in place of revolving cylinders.
By the improved method of construction and arrangement described, the apparatus
is made more simple, cheap, and effective, and occupies less room, than in machines
as heretofore used. It may be applied to machines in which the paper or other
material passes over the surface of one or more cylinders, or where it passes over flat
tables.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is:-
In apparatus for applying bronze or other powder to the surface of paper or other
material the bar a covered or provided with a suitable soft material a¹, and made to
move backward and forward in the direction of its length by means of the stud c and
grooved cylinder d, or other equivalent means, substantially as and for the purpose
described, and shewn in the drawing.
