Improvements in Machines for Applying Bronze or other Powder
to Printed or other Matter on Paper or other Material.
I, WILLIAM KLEINERTZ of 8 Fountain Street, Manchester in the County of
Lancaster, Lithographic Printer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to an improved machine for applying bronze or other powder
to printed or other matter on paper or other material, and has for its object; first to
improve the action and arrangement as a gripper, second, the employment of a
radially movable table, and third, to provide means for the better & variable
distribution of bronze or other powder, in order to increase the efficiency of
such machines as regards quality and quantity of work done in a certain space
of time.
The improvements consist in the first place in the arrangement and combination
of gearing, and mode of employment, and action of a radial gripper, which is as
follows:-
At the bottom and in the centre of the frame of the machine 1 attach two levers
which oscillate upon a rocking shaft. These levers have motion imparted to them by
two discs fixed upon each end of a horizontal shaft passing through the frame of
the machine.
On the upper end of this lever I attach a gripper for the purpose of holding the
sheet or other material, while it is being operated upon.
A most important and novel feature in the movement of this gripper is, that it
passes and re-passes steadily under the roller which applies the bronze or other
powder & the polishing roller, & above the radially movable table without any
variation, until it is outside the frame of the machine when it moves round a centre
until the mouth looks downwards, to allow the sheet, when the gripper opens,
to be laid and held in its position by a flyer, until the gripper begins its. return
motion.

page_text: This radial motion of the gripper I obtain by attaching a connecting rod joined
to the underlip of the gripper, and passing down the side of the oscillating levers,
into a fixed cam at the side and bottom of the frame, as the lever passes onto the end
of its path, the connecting rod is pulled down, by the action of the cam, and therefore
turns down the mouth of the gripper, so as to allow the sheet or other material to be
laid down, as said heretofore.
The second part of my invention consists in the employment of a radially movable
table, on which the paper or other material rests, while the bronze or other powder is
applied, running by means of four grooved wheels on rails, the forward and backward
movement of the table being obtained by two rods fixed on either end of the said
table, and worked by cams keyed upon the disc shaft.
The object of this motion is, that the aforesaid table shall move in the same
radius as the lever-gripper, which it follows, and retires before the return of the
lever-gripper.
Above the said table I suitably mount a roller which applies the bronze or other
powder and a polishing roller.
The first named roller has a reciprocating motion imparted, so as to move in the
direction of its length-;-while-the-sheet-or other material is being pulled through,
both rollers are made to stop and commence instantly at any desired position of the
sheet or other material under operation.
The important feature of this part of my invention, is, that the roller applying the
bronze or other powder, and polishing roller, are caused to revolve contrary to the
movement of the sheet or other material under operation and at a considerably higher
speed than heretofore has been the case.
This method of revolving will have a tendency to throw all the bronze or other
powder to the front of the machine.
The reciprocating motion of the roller which applies the bronze, or other powder I
obtain by means of a cam fixed on its end, in which, works a fixed tongue, and the
rotary motion by a crossed strap from the polishing roller.
In order to obtain-a- more steady running' of the latter I drive the same by
means of friction pulleys instead of a strap or tooth gearing as heretofore has been
the case.

I also have placed a brush at the top of the polishing roller, for the purpose of
cleaning the polishing roller when found necessary, which by means of a swivel.
fixed outside the frame, can be turned on and off the roller, at the will of the
operator.
i
I cover the roller which applies the bronze or other powder with a substance
called sponge rubber, having a soft and pliable body, over this I place a covering
of woollen material, and the polishing roller with thick brown felt, and over that a
covering of woollen material, the same as the roller which applies the bronze, or other
powder.

The third part of my invention consists in providing means whereby a variable
supply of bronze:or other powder can be effected according to the, size of the printed
surface to be.operated upon, so as to stop instantly as soon as the said surface or sheet
is leaving the roller which applies the bronze or other powder.
This I obtain by the application of a rod, placed at the feeding board side of the
machine, which has three cams or eccentrics on its periphery. Corresponding to each
of these, eccentrics are three studs screwed into the side of one of the driving discs;
and these studs are so placed, at the will of the operator, that the vertical rod can bo
set in several positions. In order to bring the corresponding stud into contact with
the eccentrics on the rod, it is turned around and thereby the bent lever drawn 'off'
the ratchet or cam. wheel, thus instantly stopping the supply of bronze or
other powder, for the sizes, as indicated upon a disc at the side, underneath the
feeding table, this. will also allow of cleaning, or re-filling, with bronze or other
powder.

The receptacle for the bronze or other powder consists of a V shaped box called
a hopper, being made of iron, and suspended (on-pivots. fixed in the frame; just

page_text: above, and a little in front of the roller which applies the bronze or other
powder, I also have made a second loose case of tin, which I place inside the
suspended hopper, for the purpose of changing the, or refilling with bronze or other
powder.
A shaking motion is imparted to the suspended hopper, by a toothed wheel, a right
angled piece of iron running onto it, which is fixed with one end onto the side of
the hopper. This toothed wheel, is keyed upon the same stud as the friction pulley
which drives directly upon the polishing roller.
To stop the bronze from coming out of the front slit I employ a thin roller, which
does not revolve, covered with felt or other material, running direct across the front
slit inside of the machine, suspended in two small brackets, so that when the gripper
comes forward to take the sheet, it raises this roller by passing under it, and allows
to fall immediately on returning, and so effectually closing the slit and preventing
the escape of bronze or other powder.
1
The escape of the latter through all the other apertures I have effectually prevented
by placing bristle brushes inside the machine, the waste bronze or other powder being
caught in a zinc funnel and thence conducted into a zinc drawer at the bottom,
which arrangement is placed underneath the table. The drawer can be pulled out so
as to empty it.
'
At the back of the machine & just above the opening, I employ a thin rod moving
in brackets, to which I attach laths of wood, for the purpose of laying & holding
the sheet in its position, until the gripper begins to return, when it rises and repeats
the same action on each sheet, or other material, that is pulled through by the
gripper.
The said rod is actuated by means of a toothed wheel, attached to one end
thereof, gearing into a rack, which is fastened to a rod actuated by a crank, moved
by a cam.

Improvements in Machines for Applying Bronze or other Powder to
Printed or other Matter on Paper or other Material.
1, WILLIAM KLEINERTZ of 8 Fountain Street, Manchester in the County of
Lancaster, Lithographic 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:—
My invention relates to an improved machine for applying bronze or other powder
to printed or other matter on paper or other material, and has for its object, first to
improve the action and arrangement of a gripper, second, the employment of a
radially movable table, and third to provide means for the better & variable
distribution of bronze or other powder, in order to increase the efficiency of
such machines as regards quantity and quality of work done in a certain space of
time.
And in order that my invention may be more fully understood I have caused to be
appended hereunto two sheets of drawings marked with letters of reference indicating
like parts throughout the figures.
Fig. 1 Sheet I is a vertical cross section, and Figs. 2 & 3 Sheet II, side views
respectively of my improved machine..
In carrying out my invention the improvements consist in the first place in the
arrangement or combination of gearing, mode of employment and action of a radial
gripper, which is as follows:-
At the bottom and in the centre of the frame a of the machine Iſattach two levers a³,
which oscillate upon a rocking shaft b.
These levers a have motion imparted to them by two discs c fixed upon each end
of a horizontal shaft & passing through the frame of the machine.
On the upper end of this lever a I attach a gripper e for the purpose of holding
the sheet or other material while it is being operated upon..
A most important and novel feature in the movenient of this gripper e is, that it
passes and re-passes steadily under the bronzing and polishing rollers o o' and o², and
above a radially movable table 1, without any variation, until it is outside of the
frame a of the machine, when it moves round a centre g until the mouth looks
downwards, to allow the sheet, when the gripper e opens, to be laid and held in its
position by a flyer h, until the gripper e begins its return motion.
This radial motion of the gripper e I attain by attaching a connecting rod c¹ joined
to the under lip 1 of the gripper e, and passing down the side of the oscillating
levers a¹ into a fixed cam at the centre & bottom of the frame a, as the levers at
pass onto the end of their path, the connecting rods e' are pulled down by the action
of the cam, and therefore turn down the mouth of the gripper e so as to allow the
sheet or other material to be laid down onto the receiving table i.

page_text: The opening of the gripper e when at the feeding end near the slit of the machine
is performed by two cams d' see Fig. 1 keyed onto the disc shaft d one on each side.
These cams d' actuate two upright rods d², so that when the gripper e comes forward,
these rods d² are raised by means of the cams d', and come against bowls d³ placed at
the upper lip 2 of the gripper e, thus raising the same.
On the underlip 1 of the gripper e I place two bowls g¹ one on each end of the
gripper e. These bowls run into slots a³ cast on the ends of the frame a of the
machine, in the same radius as the gripper e, which prevents the gripper e from
straining when the upper lip 2 is raised.
The gripper e is made by placing two plates of steel or malleable iron 1 & 2 upon
a horizontal shaft, the under plate 1 being fastened to the gripper shaft g by means of
pins, & the upper plate 2 being loose thereon so that it can be opened. I have also
provided springs which I place upon the shaft g of the gripper, and let them come
into contact with notches cut into the side of the upper lip 2 so that when the gripper
opens and takes the sheet, these springs close the upper lip 2 firmly down upon the
sheet.
h
The flyer operates in conjunction with a receiving table i as follows:-
To the frame a on the delivery end of the machine two angular brackets a² are
attached, at the bend of which I arrange the receiving board or table i to oscillate by
means of the pivots i¹ and rod k connected thereto and to a weight lever k¹ fixed on
the shaft b. The free ends of the bracket a² are formed to receive a shaft h¹ carrying
the flyer which is actuated from a bowl d, attached to the end of the receiving
table and a trail lever h² fixed on the flyer shaft h¹ so that on the respective edge of the
receiving table moving down simultaneously with the gripper e, the bowl d depresses
the trail lever 2 and consequently brings the flyer h onto the paper and holds it down
while the gripper e begins its return motion.
In carrying out the second part of my invention my improvements consist in the
employment of a radially movable cylindrically shaped table on which the paper or
other material rests while the bronze or other powder is applied see Fig. 1.
Instead of actuating the same by means of grooved wheels and rails, I effect the
forward and backward movement of the cylindrical table by fixing the same on a
shaft m, which oscillates in the frame a.
The said cylindrical table is radially actuated by means of a cam
keyed upon
the disc shaft d which works a double rack n up and down, gearing with a segmental
pinion n' fixed on the end of the shaft m.
This rack n is jointed at the lower extremity to a lever n², and at the upper
extremities, works against the pullies n³, which serve to guide the rack n.
The object of this motion is that the aforesaid table shall move in the same
radius as the lever-gripper e, which it follows, and retires before the return of the
gripper e.
Above the said radially moving table I suitably mount a roller 0, which applies
the bronze or other powder, and a polishing roller o¹ and in front of the former, a
supply roller o².
The first named roller o has a reciprocating motion imparted so as to move in the
direction of its length while the sheet or other material is being pulled through, both
rollers o&o are made to stop & commence instantly at any desired position of
the sheet or other material under operation, the polishing roller o running
continuously.
The bronze supply roller o² may be arranged to work upon a roller placed directly
underneath, lying loosely in the frame a upon springs.
The important feature of this part of my invention, is, that the rollers applying the
bronze or other powder, o & o² and polishing roller o³, are caused to revolve contrary
to the movement of the sheet or other material under operation and at a considerably
higher speed than heretofore has been the case.
This method of revolving will have a tendency to throw all the bronze or other
powder to the feeding end of the machine.
The body of the polishing roller o¹ for lightness I form of wooden laths fixed into

page_text: -discs at each end of the shaft, and the bronzing & supply rollers o & o² hollow,
of tin.
The reciprocating motion of the roller o which applies the bronze or other powder
I obtain by means of a camp fixed on its end, or to a vertical shaft p¹ the cam p
working. between a strap p² attached to the shaft of the roller o.
с
Rotary motion is imparted to the shaft of the roller o by à crossed strap p³ and
the pulleys g g and to the cam shaft p¹, by a cord & pulleys ¹², fixed respectively
on the stud s, shaft p' & shaft of the roller o, see Fig. 3.
If deemed necessary I may place a brush at the top of the polishing roller o for
the purpose of cleaning it which by means of a swivel fixed outside the frame, can
be turned on and off the roller o at the will of the operator.
I cover the bodies of the rollers o & o² which apply the bronze or other powder,
with a substance called sponge rubber, having a soft and pliable body, over this I
place a covering of woollen material, and the polishing roller o with thick brown felt,
& over that a covering of woollen material, the same as the rollers o & o² which
apply the bronze or other powder.
The polishing and bronzing rollers o & o¹ are both under the influence of screws
and springs
so as to subject the same to any required amount of pressure.
In carrying out the third part of my invention my improvements consist in
providing means whereby a variable supply of bronze or other powder can be
effected according to the size of the printed surface to be operated upon, so as to
stop instantly, as soon as the said surface or sheet is leaving the roller o which
applies the bronze or other powder.
This obtain by the application of a rod t placed at the feeding board end of
the machine, which is provided with two cams or projections t¹ actuated upon by
two studs screwed adjustably into the side of one of the driving discs c, these
studs being so set that at the will of the operator, the turning of the vertical rod t
can be effected at various intervals as follows:-
. The top-of this rod t I provide with a pinion t³, which I bring to gear with a
rack carrying a strap fork t³, which serves to move the cross strap p³, driving the
bronzing rollers o onto a loose pulley employed on the studs at the side of the
pulley on one of the studs t2 coming into contact with one of the projecting
cams on the rod t; thus stopping the bronzing rollers o and o², which also allows
of cleaning or re-filling the hopper with bronze or other powder.
:
The receptacle for the bronze or other powder consists of a V shaped box called
a hopper being made of iron, open at the top and bottom, and suspended on pivots v²
fixed to the frame a, just above and a little in front of the roller o², which supplies
the bronze or other powder, I also have made a second loose case of tin 2, with
a wire gauze bottom, which I place inside the suspended hopper v, for the purpose
of changing or re-filling it with bronze or other powder.
The case may be made of various lengths to suit the size of work to be
operated upon.
A shaking motion is imparted to the suspended hopper v, by a toothed wheel
or cam w, a right angled piece w¹ running onto it, the end of which is connected to
one end of the hopper v.
This toothed wheel or cam w is keyed upon the same stud from which is driven
the polishing roller o¹, or on the stud s, from which the supply and bronze rollers o & o²
are actuated.
The sides of the frame a are each formed with slots a³ which are covered with
bristles to prevent the escape of bronze or other powder, at the same time permitting
the gripper e to pass in and out of the machine.
The slit on delivery end of the machine is covered with a slip of cloth s² or other
material suspended vertically, and the feeding end being covered by the front board a',
hinged to the top, and can be opened and closed at will, and is furnished with a
window which enables the operator to see the paper or other material while introducing
it into the machine so as to ensure its proper position.
To prevent the waste bronze or other powder from being lost, the same is caught in

page_text: a zinc funnel or hopper æ and thence conducted into a drawer at the bottom, which
arrangement is placed underneath the cylindrical table i.
The drawer can be pulled out so as to empty it and the hopper x is provided with
a door to facilitate inspection of the interior.
For the purpose of preventing the agitation of the bronze in the machine I arrange
vertical partitions between the rollers o, o¹ and o².
At the feeding end of the machine I have arranged a row of pins el see Figs. 1 & 2 for
feeding the sheet against. When the gripper e comes forward to take the sheet these
pins el are raised by means of a rod e² see Fig. 2. and lever e³ which latter carries
the pins el while the whole length of the sheet is being operated upon, and descending
again in time for the next sheet.
The shaft d is rotated from the driving shaft by means of the spur wheels f¹ & f²,
and the polishing roller o from the driving shaft by means of a crossed strap g² see
Fig. 2. and pulleys g³ g³, g rotating loosely on a stud g³, and the open strap 9°, &
pulley g', keyed on the shaft of polishing roller o³, the supply roller o² being driven
from the pulleys on the studs, cords & pulley s see Fig. 3.
The driving shaft carries the driving pulley f3 and pulley, the latter trans-
mitting motion to the studs by means of the open strap fs and pulley f.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is
In machines for applying bronze or other powder to printed or other matter on
paper or other material:
1st. The employment & action of a lever gripper e for the purpose of holding the
paper or other material under operation and bringing the same out of the machine,
substantially as set forth.
2nd. The use of a radially moving table i in combination with a lever gripper e,
substantially as set forth.
3rd. The disc c furnished with adjustable studs t2, acting upon cams or projections t
fixed on a vertical rod t, for the purpose of interrupting and re-starting the rotation
of the bronzing rollers o & o2, and hopper v, substantially as set forth.
