Surfaces of Paper, Card, Fabric, and the like, also to Transfers for
the Retransferring on to China, Glass, Stone, Wood and the like.
I, WILLIAM BREWER SILVERLOCK, of 92, Blackfriars Road, in the County of
Surrey, Printer, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved machine for applying bronze and other
powders to printed surfaces of paper, card, fabric and the like, also to transfers
for retransferring on to china, glass, stone, wood and the like.
'
The machine has a large cylinder mounted on bearings in a suitable frame and
against or in touch with the cylinder I place coating rollers (taking their supply
of powder from a trough or hopper), oscillating pad or pads, rollers covered with
suitable material for cleaning, polishing and wiping the surplus powder from
the sheets, also a delivery roller having a reversible cleaning roller or brush on
top which first guides and then cleans the powder off the tail end of back of sheet.
There is another roller in frictional or other touch with this delivery roller which
nips the top of sheet and draws it away from machine into delivery tray.
All these rollers and pads have their adjustable bearings and the rollers are
made of different sizes and revolve at different speeds.
I use different hoppers or troughs also arrange their positions (in rotation to
the cylinder) to suit the work to be done.
The cylinder has one or more grippers,, there is also a feed table and all the
necessary mechanical arrangements for carrying the sheet through the machine
during the process of coating etc.
The sheets to be coated are first printed on a lithographic or printing machine
or press in some sticky ink or varnish, the sheets are then fed to the grippers of
coating machine. Sometimes a continuous roll of paper or other material has to
be coated in which case a special machine is used for printing the ink or varnish.
A special provision is made for keeping the dusting off (cleaning rollers) free
from powder also for preventing the powder from flying about the box in which
the rollers are placed.
The coating roller has a scraper or brush to regulate the powder. The cleaning
rollers have the same or some such provision.
The design or designs are first printed in the ordinary way upon paper or any
other suitable material in gold size or of a suitable varnish, and is then passed
through the apparatus.
" main
In carrying my invention into practice I construct the apparatus with a suitable
metallic frame having bearings in which revolves at a proper speed, driven by an
endless band from a steam engine or power, a cylinder, herein termed the
cylinder provided with the ordinary grippers of the kind by which sheets of
paper fed to it simply form a feed table are seized and carried round the main

page_text: cylinder and between rollers and brushes from which they are finally delivered
over, a number of various size cylinders or rollers, and brushes into a tray or the
like.
By the side of the main cylinder I provide a bronze box or hopper in which
the bronze powder is placed and in this said box or beneath I provide a coating
roller and a brush roller, also a brush roller going the opposite way to the cylinder
for brushing the spare powder off which falls into a drawer. There are two drawers
placed one above the other in the frame of the machine, so that when one is with-
drawn the other is in use to catch the spare powder. At the ends of the drawers
I provide a pad and below the said drawers a gridiron pad curved to the shape of
the circumference of the main cylinder. Below the aforesaid main cylinder and
drawers I provide three quick speed cleaning rollers with a portable tray or drawer
at the base. Also I place on the other side of the main cylinder two or more
large quick speed polishing and wiping rollers and small rollers, then a drawing
roller and reversible brush on top for cleaning the surplus powder from back
of sheet and the said powder will fall into a suitable catch on the exit of the said
sheet from the machine.
Also if preferable I make a machine with a hopper with a perforated bottom
having an upward or downward movement so that the powder is shaken through
the apparatus on to the colour or bronzing roller. This roller (or any other roller)
may readily be removed from the apparatus for cleaning purposes and in this
case I place the two drawers for catching the bronze in a case. Beyond the said
bronzing roller I place a pad and gridiron pad with a reversible roller going the
opposite direction to cylinder at the bottom of the main cylinder or box which has
bearings for the rollers mounted on wheels; also I place two or more large quick
speed polishing and wiping rollers on the other side of the main cylinder a small
roller all going the reversible way to cylinder, brush, and catcher above described.
Below the reversible dusting and large quick speed polishing and wiping rollers
I provide a series of channels by placing a number of plates parallel to each other
for the purpose of acting as shoots down which the spare powder will fall and be
discharged into drawers, troughs, or trays, portable or otherwise.
All the aforesaid rollers are placed parallel to and with the main cylinder and
are made to revolve in bearings attached to the frame or the box, also each roller
or pad is driven by a pulley or cam with endless bands so that the power from
the driver is conveyed to the followers on each roller to revolve forward or move
backward as required for the due performance of the apparatus.
The machine can be mounted on a suitable stand, boxed or cased in any desired
manner.

Improved Machine for Applying Bronze and other Powders to Printed
Surfaces of Paper, Card, Fabric, and the like, also to Transfers for
the Retransferring on to China, Glass, Stone, Wood, and the like.
I, WILLIAM BREWER SILVERLOCK, of 92, Blackfriars Road, in the County of
Surrey, Printer, do hereby declare the nature of this invention and in what manner

page_text: the same is to be performed to be particularly described and ascertained in and
by the following statement:-
My invention relates to an improved machine for applying bronze and other
powders to printed surfaces of paper, card, fabric and the like, also to transfers
for retransferring on to china, glass, stone, wood and the like.
And in order that my invention may be thoroughly understood I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
The drawing represents a side elevation of the machine.
The machine has a large cylinder a mounted on bearings in a suitable frame b
and against or in touch with the cylinder a I place a coating roller c taking its
supply of powder from a trough or hopper d.
Oscillating pad or pads e, for rubbing the bronze or powder rollers of covered
with suitable material for cleaning, polishing and wiping the surplus powder
from the sheets, also delivery rollers g one of which has a reversible cleaning
roller which clean the back of sheets. Brush i guides the sheets to rollers g, h.
Two of the rollers
and nips the top of sheet and draws it away from machine
into delivery tray j.
All these rollers and pads have their adjustable bearings and the rollers may be
made of different sizes and revolve at different speeds.
The cylinder has one or more grippers, there is also a feed table and all the
necessary mechanical arrangements for carrying the sheet through the machine
during the process of coating etc.
The sheets to be coated are first printed on a lithographic or printing machine
or press in some sticky ink or varnish, the sheets are then fed to the gripper or
grippers of coating machine. Sometimes a continuous roll of paper or other
material has to be coated in which case a special machine is used for printing
the ink or varnish.
A special provision is made for keeping the dusting off (cleaning rollers) free
from powder also for preventing the powder from flying about the box 7 in which
the rollers are placed.
The coating roller has a scraper m or brush to regulate the powder. The clean-
ing rollers have scrapers n or.some such provision. n is the trough.
The design or designs are first printed in the ordinary way upon paper or any
other suitable material in gold size or of a suitable varnish, and is then passed
through the apparatus.
In carrying my invention into practice I construct the apparatus, with a suitable
metallic frame having bearings in which revolves at a proper speed, driven by
an endless band from a steam engine or power, a cylinder a herein termed the "main
cylinder" provided with the ordinary gripper or grippers of the kind by which
sheets of paper fed to it simply from a feed table k are seized and carried round
the main cylinder a and between rollers and brushes from which they are finally
delivered over a number of various size cylinders or rollers, and brushes into a tray
or the like.
Below the aforesaid main cylinder a and drawers I provide three quick speed
cleaning rollers f with a portable tray or drawer at the base. Also I place on
the other side of the main cylinder two or more large quick speed polishing and
cleaning rollers f¹ and then a drawing roller and then two reversible rollers the
top one for cleaning the surplus powder from back of sheet and the said powder
will fall into a suitable catch on the exit of the said sheet from the machine.
Beyond the said bronzing roller I place a pad and gridiron pad with a reversible
roller going the opposite direction to cylinder at the bottom of the main cylinder
or box which has bearings for the rollers mounted on wheels; also I place two
or more large quick speed polishing and wiping rollers on the other side of the
main cylinder a small roller all going the reversible way to cylinder, brush, and
atcher above described. Below the reversible dusting and large quick speed

page_text: polishing and wiping rollers I provide a series of channels by placing a number
of plates parallel to each other for the purpose of acting as shoots down which
the spare powder will fall and be discharged into drawers, troughs, or trays,
portable or otherwise.
All the aforesaid rollers, are placed parallel to and with the main cylinder and
are made to revolve in bearings attached to the frame.
The machine can be mounted on a suitable stand, boxed or cased in any desired
manner.
The table is raised and lowered by a cam p at lever 21. I sometimes have
two drawers o, o, so that one may be emptied whilst the machine is in motion.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is
--
1. In a bronzing machine, the combination and arrangement of the bronze or
powder trough which is easily and quickly emptied or cleaned out and in which the
powder falls into a drawer or catcher underneath, I sometimes have two
drawers o, o,, so that one may be emptied whilst machine is in motion, substan-
tially as herein described and illustrated in the accompanying drawing.
2. The combination and arrangements for cleaning the back of sheets, substan-
tially as and, for the purpose described and shewn in' the drawing.
3. The combination of the direct action lever and cam for raising and lowering
the feed table or "laying on "table, substantially as and for the purpose described
and shown in the drawing.
4. The bronzing machine substantially as above described in this specification
and shewn in the drawing.
