"IMPROVEMENTS IN
LOZENGE MACHINES." [A communication from abroad by Thomas Robertson, of
Toronto, in the Dominion of Canada, Mechanical Engineer.]
The Invention relates to the manufacture of printed, stamped, embossed, and plain
lozenges, and may be divided into six principal parts, viz. :-
First. Printing the paste as it lies on the cutting table. This is accomplished by
a printing block or head, with adjustable dies affixed, attached to sliding standards
and worked by a suitable arrangement of levers.
Second. Cutting the sheet of paste as it lies ou the cutting table, either after
printing or when plain, into lozenges of any desired shape or size. This is accom-
plished by the action of adjustable hollow dies or cutters affixed to a cutting head,
to which a reciprocating up-and-down motion is given by a pair of revolving wheels,
each having an eccentric channel sunk in its face, in combination with sliding side
standards, to which the cutting head is attached.
Third. 'Removing the lozenge, when cut, from the hollow dies, and placing the
regularly upon suitable drying frames. This part of the Invention is effected by
the action of pushers attached to a reciprocating horizontal frame, which push the
lozenges as they are crowded up through and above the top of the die at each cut,
[Price 8dl

page_text: on to a travelling shelf to conveyors which deposit each set of lozenges cut in each
revolution, on frames covered with bolting cloth or other suitable material.
Fourth. Feeding the cutting table and drying frames forward autimatically.
This portion of the Invention is performed by the action of an eccentric keyed to a
revolving shaft, in combination with and working within the end of a pivoted
lever, whose opposite end fits in a toothed track sunk in the bottom of the cutting
table.
Fifth. Embossing the faces of lozenges, after they are cut and printed, by means
of a reciprocating head.
Sixth. In the apparatus devised for receiving the lozenge frames as they pass
through the machine laden with lozenges, which apparatus consists of a portable
frame fitted as an elevator to move up and down at the delivery end of machine.
This frame is provided with castors, on which, when loaded, it can be rolled into the
drying room without any handling of the lozenges or lozenge frames.
The frame of the machine is constructed of iron or other material, and consists of
two sides, connected by bolts and girders. At or near the centre of the machine is
placed the mechanism for cutting the lozenges; at the front end the printing
apparatus; at the rear end the moulding mechanism. The paste is received on the
travelling cutting table in an evenly spread and regular sheet from a pair of rollers
placed at the front end of the machine.
The cutting table is rabbeted out near the edge, and fits on guides which extend
the whole length of the machine, and are fastened to a broad flange cast on the top
of the sides. In the centre of the bottom of the cutting table a toothed rack is
inserted. The printing head or block is fastened at each end to upright sliding
standards. To these standards are attached adjustable printing dies, having on their
under faces the mottoes or designs to be printed. The standards are connected by
a wide cross girder, which is attached in the centre to a lever by which the standards
and attachments are operated:
The driving shaft of machine revolves in suitable bearings, and on the shaft of
which are affixed a driving pulley with clutch coupling, fly wheel, and pinion gearing
into a wheel attached to a counter shaft. On the ends of the shaft, outside the
frame, are attached cam wheels. An eccentric channel is sunk in these wheels on
the inner face, in which are placed at the top of the channels, friction rollers,
attached by a pin in the usual way to standards. As the wheels revolve an up-
and-down reciprocating motion is imparted to the standards working within guides
and all their connections, the length and character of the stroke depending on the
shape of the eccentric channel. Where the friction roller pins connect, adjustable
sliding boxes are placed.
The tops of the standards are made to hinge, for convenience in putting in and
taking out the cutter heads. When the heads are in position they are secured by screws.
The hollow cutters or dies are attached to the head by screws.
The cutters may
be of any desired shape or size, but must be hollow in order that each lozenge as it
is cut may force the lozenges cut before it one thickness up. From this it will be
seen that each revolution of the wheels forces one set of lozenges above the cutters,
whence they are removed.
:
The peculiar shape of the eccentric channel is one of the features of the Invention.
By it I am enabled not only to lower and raise the cutting head, but also to
keep the cutting head stationary à sufficient length of time when at the top of
the stroke to enable the pushers to remove the lozenges and retire. The channel
operates both head and pushers, actuating the head when the pushers are at rest,
and vice versa.
The cutters are a peculiar feature of the machine. The base holds the lozenges
until they are forced up by each succeeding set above the rim. The holder is
attached to the head by stems, leaving the front and rear of the cutters open above
the base, thus allowing the pushers to pass above the base and between the stems,
shoving the lozenges out on the shelf.
Working at the bottom of the eccentric channels are friction rollers attached to

page_text: pivoted levers which are connected to the frame. This connection, when the
machine is in operation, imparts a horizontal reciprocating motion, the length
of the stroke being regulated by the length of the arms, and is turned so that
the pushers come forward when the head has risen, and shove the uppermost
set of lozenges on the shelf, and retire again before the head begins to descend on
the next stroke.
The lozenge conveyors consist of a series of parallel bars attached to a recipro-
cating frame by a hinged joint, and working in connection with an inclined plane,
the lozenges are conveyed from the intermittently moving sliding shelf which receives
them from the pushers by the first of these travelling bars, which moves them a
certain distance on the inclined plane at one stroke of the machine; at the next
stroke, the second bar takes the row of lozenges left by the first bar, and moves
them the length of the stroke, while the first bar receives another from the
sliding shelf, and so on successively throughout the whole series of bars, until the
lozenges are deposited on the receiving frame which are fed from underneath the
inclined plane forward the width of a row of lozenges at each stroke of the
machine.
The action of the several operating parts is made to correspond one with the
other, so that the cutting of the lozenges and the feeding of them forward is one
continuous operation. The inclined plane upon which the conveyors operate, is
elevated to allow the cutting table and receiving frames to be fed forward under-
neath. Cam latches are placed at intervals on the inclined plane, corresponding
to the position of the rows of lozenges as they are left by the conveyor bars. These
cam latches lift the bars as they pass backward, and allow them to pass behind the
lozenges in order to draw the lozenges forward on the return stroke.
The lozenge frames are covered with bolting cloth or other porous material,
in order to facilitate the passage of air to the lozenges for drying. These boards,
when they are covered with lozenges, are slipped into the elevator rack.
The elevator rack which receives the lozenge frames is rectangular, and is hung
by a chain or rope in such manner that it can be raised or lowered as required, in
order to slide the frames in or out. The elevator can also he detached from its
guides, and by means of castors attached to it, be moved from place to place loaded
or unloaded.
In the centre of the driving shaft is affixed an eccentric, over which passes the
open end of a pivoted lever, which is pivoted on a bracket fastened to the girder of
frame. The upper end has attached a spring pawl with latch point fitting into the .
rack let into the bottom of the cutting table. The length of the upper and lower
lever arms is so arranged that at each revolution of the shaft. one notch of the
rack is fed forward. The length of these notches agrees with the width of the
lozenges, allowing some space, of course, for the cutters to clear themselves at each
stroke. The cutting table butts against the receiving frames, and the forward motion
is thus communicated to the frames, impelling them the exact distance required for
the clear deposit of each new row of lozenges. A system of levers worked from a
cam placed on the outside of the driving wheels operate a horizontal bar, giving to
it an up-and-down motion.
When the lozenges are shoved forward on the shelf by the pushers, from the nature
of the paste they are apt to stick to the pushers. This bar just at the turn of the
stroke, comes quickly down upon, and lightly but sufficiently presses the lozenges,
and holds them until the pushers begin to recede, when it is lifted out of the way.
When the lozenges are to be pressed or embossed, they are deposited upon a plate
or head on the inclined plane by the action of the conveyors. The moulding heads
are of such a length that they take in one entire row of lozenges. The head is
attached to outside sliding standards connected to the driving wheels of machine,
and worked in bearings attached to the frame.

the said Herbert John Haddan in the Great Seal Patent Office on the 27th April
1878.

<6 IMPROVEMENTS IN
LOZENGE MACHINES." A communication from abroad by Thomas Robertson, of
Toronto, in the Dominion of Canada, Mechanical Engineer.
My Invention has relation to the manufacture of printed, embossed, and plain
lozenges by machinery, and it consists,―
First. In the novel construction and arrangements of attachments, to the rolls
which facilitate the reduction of the lozenge paste to the required thickness, and
deliver it in a sheet upon the cutting table.
Second. In the means provided for printing the paste as it lies in a sheet upon
the cutting table.
Third. In the means provided for cutting the paste as it lies on the cutting
table, either after printing or when plain, into lozenges of any desired shape or
size.
Fourth. In the means provided for removing the lozenges from the cutters; and
conveying them to and placing them in regular rows upon drying trays.
-
Fifth. Of an embossing or printing head, which, moving to correspond with the
action of the lozenge conveyors, emboss or print the rows of lozenges as they are
passed under it..
Sixth. In the apparatus desired to receive the lozenge drying trays as they pass
out of the machine laden with lozenges, which apparatus consists of a portable
frame fitted as an elevator to move up and down at the delivery end of the machine,
and provided with tray bearings, on which the trays can be placed one above the
other. This elevator frame is fitted with castors, on which it can be rolled in and
out of the drying room without any handling of the lozenges or lozenge trays.
In the accompanying Drawings,
Figures 1, 2, & 3 are side views of contiguous portions of a machine embodying
my improvements, the different views when taken together forming the whole side
elevation.
Figures 4 and 41 are cross sections.
Figure 5 is a longitudinal section through cutting head.
Figures 6, 7, 8, 9, 10, 11, & 12, details of operating parts.
A is the frame of the machine constructed, as shown, of iron or other material,
consisting of two sides, connected by bolts and girders. At or near the center of
the machine is placed the mechanism for cutting the lozenges; at the front end, the
rolling and printing apparatus; at the rear end, the embossing and elevating
mechanism.
Figure 2 shows the rolling mechanism for reducing the lozenge paste to the
required thickness. This mechanism is placed at the front end of machine, and
performs the first of a successive number of operations in the mechanical manufac-
ture of lozenges, by my process, in a single machine. The paste is received from the
kneader, and passed through the rollers B, falling upon a board, which is arranged
to slide forward as the sheet of paste is delivered; this board is then moved forward
and deposited upon a hinged frame B'. The frame is pivoted to the axle of the
next roller, and is arranged to be lifted up to and supported at an angle, from which
the paste is fed easily between the second and last pair of rollers B²; these rollers
are adjustable to vary the thickness of the sheet of lozenge paste as required. The
paste from the rollers B2 is fed directly upon the cutting table of the machine. B³
is a brush mounted on the end of the arms b, and revolved by a strap connection
from a pulley on one of the roller shafts. The weight of the brush and supporting
parts is counterbalanced, in order that it may be drawn up out of the way when not

page_text: in use.
The necessity for a brush occurs in the fact that in working lozenge paste
a large amount of starch powder has to be used to prevent the paste sticking; this
powder, before the lozenge sheet passes to the printing head, must be removed in
order to get a clear impression from the type.
The paste is received on the cutting table C in an evenly spread and regular sheet.
The cutting table C fits on slide bars A¹, which extend the whole length of the
machine, and are fastened to a broad flange cast on the top of the sides. In the
center of the bottom of the cutting table C a toothed rack C' is inserted. D is
the printing head or block, fastened at each end to the upright sliding standards D¹.
To D are attached the adjustable printing dies D2, having on their under faces the
mottoes or designs to be printed. Any convenient number of mottoes may be placed
on one die; d are die spindles, around which are placed spiral springs for regulating
the pressure on each die, and also the pressure that can be applied in printing the
mottoes on the paste. The compressive strain on these springs is regulated by a nut
on the spindle d above the printing block D³. The standards D¹ are connected by a
wide cross girder K, which is attached in the center to the lever D³, by which the
standards and attachments are operated.
The weight of the head, &c., can be counterbalanced by a weight or by friction.
E are bevel wheels attached to a shaft E3, and operated by a handle E¹. The end
wheels gear into wheels which are attached to short shafts, on which are placed spur
wheels, which fit into a toothed rack sunk in the bottom of the cutting table.
E is
a spring stop, which fits into notches sunk in the under side of the cutting table, and
is withdrawn by means of the lever e. These notches are sunk at regular intervals
to agree with the width of the dies D².
The object of the spur wheels and stop is to enable the operator to cause the
cutting table to travel regularly forward after printing a portion of the sheet, and
to stop exactly in the right place for the next impression on the sheet. The front
spur wheel propels the table forward nearly its whole length; the next wheel then
catches it, and forces it forward under the cutting dies.
F is the driving shaft of machine, revolving in suitable bearings, on which are
affixed the driving pulley F', with clutch coupling, fly wheel F2, F³, and pinion F*
gearing into the wheel F5 attached to the countershaft F. On the ends of the
shaft F, outside of the frame A, are attached the wheels G. An eccentric channel g.
is sunk in these wheels, in which are placed at the top of the channels the friction
rollers G¹, attached by a pin in the usual way to the standards G. As the wheels
revolve an up-and-down reciprocating motion is imparted to the standards G²
working within the guides G3 and all their connections, the length and character of
the stroke depending on the shape of the eccentric channel g. Where the friction
roller pins connect with G2 adjustable sliding boxes G4 are placed; these boxes are
adjusted by the screws G5, and are pressed down upon a rubber bearing Gº.
The tops G7 of the standards G2 are made to hinge for convenience in putting in
and taking out the cutter heads H. When the heads H are in position they are
secured by the screws h. I are the hollow cutters or dies attached to the head H
by screws; these cutters may be of any desired shape or size, but must be hollow
in order that each lozenge as it is cut may force the lozenges cut before it one
thickness up. From this it will be seen that each revolution of the wheels G
forces one set of lozenges above the cutters, whence they are removed, as herein-after
specified.
The peculiar shape of the eccentric channel g is one of the features of my Inven-
tion. By it I am enabled not only to lower and raise the cutting head H, but also
to keep the cutting head stationery a sufficient length of time when at the top of
the stroke to enable the pushers J to remove the lozenges; and retire. The channel g
operates both head and pushers, actuating the head when the pushers are at rest,
and vice versa.
་
The cutters I are another peculiar feature. The base I¹ holds the lozenges until
they are forced up by each successive set above the rim. The holder is attached
to the head by stems I2, leaving the front and rear of the cutters open above the

page_text: base, thus allowing the pushers J (see Figure 5) to pass above the base and between
the stems, shoving the lozenges out on the shelf J'.
Working at the bottom of the eccentric channels g are the friction roller K,
attached to the pivoted levers K', which are connected to the frame K², as shown
in Figure 1. This connection, when the machine is in operation, imparts to K2 a
horizontal reciprocating motion, the length of the stroke being regulated by the
length of the arms K, and is timed so that the pushers J, Figure 5, which are
attached to K2, come forward when the head H has risen, and shove the uppermost
set of lozenges on the shelf J', and retire again before the head begins to descend on
the next stroke.
The
To each end of the sliding frame K2 are attached the lifters K³ having the in-
flected slot K; K5 is the lifting bar, worked by means of the bearings K placed
within the slot K. This bar follows the cutters on their upward stroke, and,
pressing against their base, lifts up the lozenges, which are inclined to drop; Kare
rods attached to the lifting bar K5 at one end, the other end passing through a hole
cut in an upright standard. Around K7 are coiled spiral springs, pressing at .one
end against the bar K³, the other ends pressing against the standards. The object
of these rods is to cause the bar K5 to rise by means of the bearings Ke in the in-
flected slots. K before the frame K2 has reached the end of its forward stroke.
springs hold the bar K5 in position during the operation. The end of K7 is threaded
and fitted with a nut, so that the bar may be caused to rise at any part of the
stroke. To the front of the bar K5 is attached by thumbscrew a guard Ks. This
guard is so arranged and cut that, when the cutters I are down, it fits closely
around and between the cutters, and prevents the paste clinging to the cutters when
they rise. The position of this guard above the paste can be regulated by thumbscrews.
The delivery of the lozenges to the conveyors from the pushers is accomplished,
by an independently moving shelf J¹. This shelf is operated to move to and from
the cutters to the end of the inclined plane by the rod and bell-crank connection.
connected with the sliding standard G².
Lis an inclined plane over which the lozenges are passed in their delivery by con-
veyors from the cutters to the lozenge trays M. This plane is placed at an elevation
above the level of the receiving trays, so that the latter may be passed out from
underneath; being fed forward by suitable mechanism in unison with the delivery
of the lozenges at the end of the inclined plane. The end of the plane, next the
cutting head, is placed at or about a level with the top of the cutters, while the
other end is placed as low as possible to allow the lozenge trays M to pass out freely
from underneath. The plane L is supported in an adjustable manner upon side
girders L¹, L. On the upper face of the girders L', L', in suitable bearings, a frame
L2 is arranged to work with a reciprocating back and forward motion, which
motion is communicated from the wheels G, G, by crank pin and rod connection
L³, L. To the inside face of the bars L5 a series of conveyor bars L are pivoted in
such manner that they travel along the face of plane L, each drawing a row of
lozenges forward to the end of their stroke.
In order that a progressive movement may be given to the lozenges, a series of
cams L7, corresponding to the position and stroke of the conveyors, are pivoted to
the inside faces of the girders L, L. Over these cams the conveyor bars are forced
to rise on the back stroke clearing the lozenges which had been deposited on the
previous stroke, and dropping to the plane at their rear ready for another progressive
movement. On the forward stroke of the conveyor bars, the cams L7 are simply
lifted up, dropping into place again when the bars pass.
.
The movements of the several parts are arranged to coincide one with the other,
and the several parts are also made adjustable in order to insure correct work. The
use of the shelf could be dispensed with, if desired, by extending the bars L³ beyond
the cutter head, and fastening the lozenge pushers J directly thereto.
The trays M are covered with bolting cloth, or other porous material, in order to
facilitate the passage of air to the lozenges for drying.
In the center of the shaft Fe is affixed an eccentric N, over which passes the open

page_text: end of the pivoted lever N¹. N¹ is pivoted on a bracket N2 fastened to the girder n.
The upper end of N' has attached a spring pawl N³, with latch point fitting into
the racks C, let in the bottom of the cutting table. The length of the upper and
lower lever arms N¹ is so arranged that at each revolution of the shaft F6 one notch
of the rack C is fed forward. The length of these notches agree with the width of
the lozenges, allowing some space of course for the cutters to clear themselves at
each stroke. The cutting table butts against the receiving trays, and the forward
motion is thus communicated to the trays, impelling them the exact distance re-
quired for the clear deposit of each new row of lozenges. O is a system of levers
worked from and which operate a horizontal bar O', giving to it an up-and-down
motion.
When the lozenges are shoved forward on the shelf J by the pushers J¹; from the
nature of the paste they are apt to stick to the pushers. This bar, just at the turn
of the stroke, comes quickly down upon, and lightly, but sufficiently, presses the
lozenges, and holds them until the pushers begin to recede, when it is lifted out of
the way.
P is an embossing head; which can also be used for printing the lozenges after
they are cut. This head is operated from the channelled wheels G, G, by the
levers P¹ and rods P2, P3. The time of the stroke of this head is arranged so as to
press or print the lozenges while they are stationery on the plane L, a suitable
detachable platen Q being inserted in the plane immediately under the head, on
which one of the conveyor bars places the successive rows of lozenges in an in-
variable position at each stroke. The head proper is provided with a separate
embossing block for each lozenge, connected to the head in such manner that they
may be readily removed when a change of design is required. When the head is
used for printing, suitable stereotyped plates are attached, and either inked by
hand or by any of the usual automatic inking mechanisms. In order that the
position of the lozenges may be true with the dies and types, notches are cut in the
edge of the conveyor bars, which notches retain the lozenges in place during move-
ment. The conveyor bars are also made adjustable.
I do not confine myself to any particular position for the head P over the plane L,
or to any particular mode of operating it, as such points are capable of alteration
without departing from the spirit of my Invention.
R, in Figure 3, is the portable elevator frame, fitted within guides R¹, and capable
of being hoisted up, and let down from different floor levels as required. The hoist-
ing and lowering mechanism illustrated consists of a shaft S, worm S', worm
wheel S2, shaft and drum S3, S4, upon which drum the chain or rope connected with
the frame R is wound or unwound by turning the handle S³. Although the
mechanism shewn is convenient for the purpose required, it is obvious that this part
of the machinery could be much varied. The guides R' are placed at the delivery
end of the lozenge making machinery, and in the centre line thereof. The frames.
R (of which there are a number), are fitted with tray bearings R², corresponding
with the slide bars of lozenge machine, and placed at suitable intervals apart, up the
whole height of frame, to receive a lozenge board filled with lozenges in the
interval between each set of tray bearings. In operation, an empty frame is
hoisted up or let down, until the lower or upper set of tray bearings is level with
the slide bars of lozenge machine; a loaded lozenge tray is then slipped in, and
the frame R lowered or raised, until the next set of tray bearings correspond with
the machine slide bars as before, and so on until the frame is filled with trays,
as they are passed out of the machine. The frame is then hoisted up or let
down to the floor upon which the drying room is situated, and removed directly
thereto by means of the castors T on the bottom, without any handling of the
lozenge frames or lozenges.
Although I prefer to use a reciprocating cutting head and an intermittently
moving cutting table, believing this combination to produce the best results, my
machine could be arranged to work with an entirely stationery cutting head and
a reciprocating cutting table, or the cutting head could be dispensed with altogether

page_text: by attaching the individual cutters, either solidly or in a detachable manner, to the
end of the inclined plane. The essential point of this part of my Invention being
the mechanical delivery of the lozenges, as they rise one above the other in the
hollow cutters to the conveyor bars. When a stationery head is used the lozenge
sheet would be fed over the cutting table from an intermittently moving revolving
apron or travelling band.
The independent frame pusher and lozenge lifting mechanism could be dispensed
with if desired, by extending the bars beyond the cutter, and attaching the pushers
directly thereto by means of a suitable cross head. The pushers would in this case
be arranged to deliver the lozenges to the first conveyor bar direct..
