I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E. do hereby declare the nature of this invention to be as follows:-
The object of the invention is to ensure great accuracy in the printing and
embossing of the lozenges and at the same time to impart a higher and more complete
finish to each lozenge and it consists more particularly in arranging a device by
which each lozenge after being cut from a sheet of paste is pressed into a mould
where it is embossed or printed and then deposited upon a travelling tray on which
the lozenges are arranged in rows, ready to be placed in the drying room.
The sheet of paste is fed by means of an endless apron to a series of vertically
reciprocating cutting knives which cut a row of lozenges from the paste at each
descent such row of lozenges being taken away from the cutters by a corresponding
row of fingers which place them within range of a series of push bars. The fingers
are connected to a head which is hinged to the push bar frame. When the lozenges
are within range of the push bars the fingers are raised from the lozenges which in
the event of their sticking to the fingers are removed by a series of spring plates.
The lozenges deposited in a row within range of the push bars are passed forward by
the latter until they reach the end of the table where a moulding apparatus is located
provided with rows of holes into each of which a lozenge is deposited. The moulding

page_text: apparatus consists of four bars mounted equidistantly around and parallel with a
central axis or shaft the ends of the bars being supported by cross heads fixed on the
shaft. In each bar is formed a row of holes to receive the lozenges which holes
extend entirely through the bars. Between each perforated bar and the central shaft
is a rod or bar which extends through slots or guides formed in the arms of the cross
heads. This rod is provided with pins or plungers which work in and completely fill
the holes in the perforated bar the pins thus forming movable bottoms to the holes.
The rods carrying the pins are provided at each end with anti friction bowls which
enter into cam grooves so shaped as to cause the pins to assume the required position
within the holes at different stages of the process. For brevity the moulding
apparatus above described will be hereinafter termed the cylinder or moulding
cylinder. The cylinder revolves between two horizontally reciprocating carriages one
of which carries a row of plungers and the other a row of cleaning brushes both the
plungers and brushes fitting when in use into the holes in the cylinder. The ends of
the plungers may be engraved so that when impressed upon the lozenges the design
will be stamped thereon. The moulding cylinder is operated by ratchet and pawl
mechanism and revolves a quarter of a revolution at each movement. Supposing the
cylinder to be stationary a row of lozenges are fed to the upper row of holes in
the cylinder by means of the pusher-bar. A quarter of a turn is then given to
the cylinder which places the row of holes containing the lozenges opposite the
reciprocating plungers which enter the holes and impress their design upon the
lozenges. A second quarter turn places this row of holes vertically downwards and
the lozenges are projected from their holes or dies on to a travelling table or apron
the motion necessary to cause this projection being imparted to the rod carrying the
pins which form the bottoms of the holes by means of suitable revolving cams levers
and rods. A third quarter turn places the empty holes opposite the cleaning brushes
and the fourth quarter turn brings them back to the starting point ready for another
row of lozenges. There are thus four stages in the cycle of operations and as there
are four rows of holes there are four rows of lozenges completed for each complete
revolution of the cylinder.
Beneath the reciprocatory plungers are mounted a series of brushes which are
capable of oscillating on a beam or beams. As the plunger frame reciprocates the
rear portion thereof comes in contact with an incline on one end of the rocking beam
and depresses it raising the other end with the brushes in front of the plungers the
ends of which come in contact with the brushes and are thoroughly cleaned thereby.
Other brushes are so placed as to clean the ends of the internal plungers or projecting
pins immediately after the discharge of the lozenges from the holes in the cylinder.
The different motions of the parts described are obtained from three principal
shafts one of which carries the cams or cranks for operating the cutting knives. A
second one by means of suitable levers and rods imparts the intermittent revolving
motion to the cylinder and reciprocatory motion to the pusher bars and from the third
shaft the necessary reciprocatory motions are imparted to the frames carrying the
printing plungers and the cleaning brushes.
Each of the printing plungers is attached to a spindle which passes through holes
made in the carrying frame and the amount of pressure exerted by the plungers is
regulated by means of spiral springs passing round the said spindles.
The cam or cams which impart the necessary movement to the internal plungers is
so shaped that the plungers when the plate is in position to receive the lozenges are
almost flush with the surface of the perforated bar so that when the lozenges are
deposited in the holes they will each rest upon their respective plungers. When the
bar thus filled is removed from its first position to the horizontal position opposite to
the printing plungers the cam is so shaped as to draw the internal plungers inwards
thereby permitting the lozenges to recede into the holes. During the next quarter of
a turn the plungers are drawn further inwards to clear them of the lozenges and then
projected outwards as previously described. They are then withdrawn entirely clear
of the bars to make way for the cleaning brushes after which they are returned to
their initial position.

page_text: A stationary plate is provided close to which the plungers must pass after having
discharged the lozenges which plate will knock off any lozenges that may adhere to
the plungers. There is also a stop provided for the purpose of arresting the motion
of the cylinder. This stop is held in a suitable guide formed in the frame and is
operated by a cam on the axis of the cylinder. This cam is so shaped that the stop is
thrown out so as to extend beyond the periphery of the cylinder when it comes
opposite the printing plunger and is withdrawn in time to allow the next movement
of the cylinder. At each end of the carriage carrying the printing plungers a conical
finger is fixed which fingers enter holes in the cylinder and so adjust it in position to
receive the plungers.

page_text: I ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
M.I.M.E., 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 :-
The object of the present improvements is to ensure greater accuracy in the printing
and embossing of the lozenges and at the same time to impart a higher and more
complete finish to each lozenge; and it consists more particularly in arranging a
device by which each lozenge after being cut from the sheet of paste is pressed into a
mould where it is embossed or printed and then deposited upon a travelling tray on
which the lozenges are arranged in rows ready to be placed in the drying
room.
Figure 1 is a side elevation showing the position of the mechanism before the cutters
have been brought down upon the paste. Figure 2 is a sectional side view showing
the mechanism in the same position as in Figure 1. . Figure 3 is a side elevation
showing the position of the mechanism when the cutters have been brought down
upon the paste. Figure 4 is a sectional side view showing the mechanism arranged
as in Figure 3. Figure 5 is an enlarged sectional side view of the moulding cylinder
and its connections. Figure 6 is a perspective detail of the moulding cylinder.
Figure 7 is a perspective detail of the cam and its lever for operating the plunger in
the moulding cylinder. Figures 8 and 9 are perspective details partially in section
showing the means for lifting the fingers employed in drawing the lozenges out of the
cutters. Figure 10 is a perspective view of the machine.
In the drawings all parts marked A represent the main or stationary frame of the
machine.
B represents the travelling apron upon which the sheet of paste is conveyed to the
cutters.
C is the cutter head which is attached to or forms part of the table D which is
hinged at a to the frame A. This table D extends across the full width of the
machine, the said width being regulated according to the number of cutters in the
head C.
E is the main driving axle of the machine and derives motion from any primary
motor desired
All the moving parts of the machine are geared to and derive motion
from the axle E.

page_text: 12 is a connecting rod attached at its upper end to the table D and at its bottom
end to a crank connected to the axle F which is geared to and derives motion from
the main axle E as indicated in Figure 2.
c is a balance weight connected to the end of the lever d which is pivoted to the
main frame A and is connected by the rod e to the table D for the purpose of balancing
the weight of the said table.
When the axle F revolves the table D being hinged at a derives a vertically recip-
rocating movement which is designed to bring the cutters against and away from the
sheet of paste alternately cach downward movement of the cutter head C being
designed to cut out from the paste a row of lozenges. As the head ascends the
fingers (see Figures 8 and 9) draw from each cutter a lozenge. As these fingers are
attached to the frame which operates the push bars as fully described in the American
Patent issued on May 9th 1882 it is not necessary here to describe the construction
and operation of the said push bars it being merely necessary to say that the fingers f
draw the lozenges from the cutters to a position where they may be reached by the push
bars which operate and are constructed in the same manner as the push bars described in
said patent the present reason for referring to the fingers being merely to explain how
the fingers are cleared from the lozenges after they have been drawn by the said
fingers into range of the push bars which as before stated are operated as described in
'the former. patent. The fingers fit will be noticed are connected to a head
g which
is hinged at h to the push bar frame i. A cam finger or pawl; is secured on each
side of the head and is slightly longer than the distance from its pivot to the top of
'the ledge k. When the fingers have reached the position in which they are shown in
Figure 9 the lozenges have been drawn into range of the first push bar. At this
point the finger or pawl falls into a notch made in the ledge k and as the head
commences to travel back toward the cutter head C the pivoted finger j raises the said
head on'its hinge lifting the fingers clear of the lozenges and in the event of the
said fingers lifting any of the lozenges any so lifted will be pushed down by coming
in contact with the spring plates m. When the head y returns to obtain a fresh supply
of lozenges as indicated in Figure 8 the pawl falls into the slot m¹ made in the
platok which slot is sufficiently large to allow the pawlj to swing on its pivot without
raising the head g; or in other words, the pawlj swings freely on its pivot when over
the slot m so that on the return stroke of the head the pawl j assumes the angle it
is, indicated in, in Figure 9 so as to be in a position to act when the head returns.
The row of lozenges deposited within range of the push bars are then drawn forward
by the action of the said push bars until they reach the end of the table D at which
the moulding cylinder G is located. This is termed a "moulding cylinder" although
strictly speaking it is not a cylinder being merely four bars n running parallel with
the axle o and supported by heads p' which are fastened to the axle o. Each of these
bars n has a series of holes q pierced in it which holes represent the size and shape of
'the lozenges to be moulded and are 'the same distances apart as the cutters so that
each lozenge cut finds a corresponding hole in the particular bar n which happens
to be at the end of the table D when the lozenges are drawn from the said table
onto the top of the bar n. Consequently each lozenge so drawn is deposited into one
of the holes q.
On reference to Figures 2, 4 and 5 it will be noticed that each hole g is provided
with a plunger which plungers are attached to a bar s extending from one head to
the other and has friction rollers' journalled on each of its ends. The axle o is
supported at each end by a bracket H which is suitably fastened to the main frame A.
On the inside surface of each of these brackets a cam groove u is made so as to receive
the friction rollers t and is shaped so as to operate the plungers r in the manner and
for the purposes hereinafter described.
A carriage is supported in suitable guides on the frame A and extends across the
machine. A corresponding carriage J is similarly supported and is located on the
opposite side of the cylinder G.
An arm K is pivoted on each side of the frame A and its upper end is connected to
the carriage. by the link -L.-

page_text: An arm M is pivoted on each side of the frame A and is connected to the arm K by
the rod N its other end being connected to the carriage J by the link O. The
lower end of the arm K is connected by the rod P to a crank pin attached to and
operated by the shaft Q which derives motion as indicated in Figures 2 and 4 from the
main axle E.
A row of plungers R are supported in suitable journals on the carriage 1 and are
designed so that each hole q shall have a plunger R immediately opposite to it when
in a horizontal position. These plungers Rare shaped so as to fit the holes
and have their ends plain or engraved so that when they are brought into contact
with the lozenges within the hole q a corresponding impression will be stamped upon
the lozenges.
On the carriage J a series of circular cleaning brushes v are arranged so as to come
opposite to the holes 9 as indicated in Figure 5.
It will be noticed that there are four bars n set at right angles to each other so that
when two are vertical the other two are horizontal. These bars are made to change
places in the following manner: An arm S is pivoted loosely upon the axle o. One
end of this arm is connected by the rod T to a crank attached to the axle U which is
geared to and derives motion from the main driving axle as indicated in Figures 2
and 4. The other end of the arm S is connected to the frame of the push bars a
which as before explained operate in the same manner as that in which they are
described in the Patent before referred to. The revolving of the axle U imparts a
reciprocating motion to the frame of the push bar a and as the moulding cylinder G
is wished to revolve so as to operate in connection with the reciprocating motion of the
push bars a pawly on the arm S is placed and a disc V is secured to the axle o. This
disc V has notches cut in its periphery which notches are four in number and at equal
distances apart corresponding with the four bars n of the moulding cylinder G. At
each backward stroke of the arm S the pawl y is brought into contact with one or
other of the notches so that at the forward stroke of the arm S the disc V is caused
to make one fourth of a revolution thereby bringing the bar n which was standing at
the top of the cylinder down to its horizontal position opposite to the plungers R
each of the other bars simultaneously being changed in their position. It therefore
follows that when the holes in the top bar n are filled with lozenges by the action of
the push bar the said bar n is brought opposite to the plunger R which is then
actuated by the mechanism herein before described so as to press the lozenges into their
respective holes and thereby finish them as mentioned. By the time that the
mechanism herein before described is ready to move the moulding cylinder another
quarter of a turn the plungers R have been withdrawn from their respective holes and
when the bar which has thus been filled reaches its bottom position the finished
lozenges are deposited upon the tray W. As the lozenges thus pressed into the holes
would not fall out of their own accord a movable gate 2 is formed in the cam groove u.
This gate is exhibited in Figure 7 and it will be noticed is connected by the rod 3 to
the pivoted lever X the opposite end of which is provided with a friction roller
resting upon a cam Y attached to the axle U. This cam Y is so shaped that the lever X
is tilted just at the moment that the friction roller t enters the gate 2 and consequently
the plungers attached to the bar s provided with the particular roller entering the gate
as referred to are forced down so as to press out from the holes the lozenges which
had previously been pressed into them by the action of the plungers described.
The next time that the cylinder G is caused to revolve the plate n thus emptied of its
lozenges is brought opposite to the brushes which are forced into the holes simul-
taneously with the plungers R on the opposite side whereby each hole is cleaned out
preparatory to being brought into the vertical position ready to receive the next
supply of lozenges. When the carriage I is moved back as hereinbefore described
its end 4 comes in contact with the projection 5 formed on the end of the lever 6.
This lever is pivoted at 7 to some convenient point in the frame A. By coming in
contact with the projection 5 that end of the lever 6 is pushed down and of course
the opposite end is correspondingly moved up so as to bring the brushes 8 which are
attached to the end of the lever against the plunger R so as to thoroughly clean them.
U

page_text: A brush 9 which extends across the machine at the point indicated brushes off and
cleans the ends of the plungers as they are carried past when moving with revolving
cylinder G. By this arrangement the faces of both plungers R and are kept clean
to insure their perfect action.
It may be mentioned here that each plunger R is attached to a spindle which passes
freely through holes made in the carriage I and is provided with a spiral spring 10
arranged to hold the spindle sufficiently stiff to enable them to perform their work
while at the same time give a little where the necessity occurs.
From the foregoing description and on examination of the drawings it will be
evident that the cam u is shaped for the purpose of imparting the necessary move-
ments to the bar s on which the plungers are attached; but in order to make the
matter clearer it may be mentioned that the said cam u is so shaped that the plungers
when the plate is in position to receive the lozenges are almost flush with the surfaces
of the barn so that when the lozenges are deposited in the holes they will each rest.
upon their respective plunger.
When the bar thus filled with lozenges is moved from its first position to the
horizontal position opposite to the plungers R the cam is so shaped as to draw
the plungers into the platet hereby permitting the lozenges to recede into the
holes q
After the plungers R have entered the holes 7 and compressed or moulded the
lozenges within them the plate n with the lozenges so moulded moves the next quarter
of a turn and the cam u is so shaped that during the movement from a horizontal to
the downward vertical position of the plate n the plungers will be withdrawn slightly
back so as to clear them of the lozenges.
7'
So soon as the gate 2 is reached the plungers return against the lozenges and push
them out as before described onto the tray W. After having so discharged the
lozenges the cam is so shaped that the ends of the plungers shall remain outside
of the plate n until they have passed the brush 9 after which they are retreated until
they are clear of the plate so that the brushes v pass entirely through the said plate
when cleaning the holes. After this point the cam is shaped so as to bring the
plungers back into their initial position.
2°
There are two other points of importance that I have omitted to refer to the first
one of which consists in placing a stationary plate 13 in such a position that the
plungers must pass close to the plate after having discharged the lozenges from the
plate n. This plate 13 is provided for the purpose of knocking off any lozenges
which may happen to adhere to the plungers r. By this plate the positive delivery
upon the tray W of every lozenge is insured. I have not referred to any mechanism
for moving the tray W as the means for doing so is fully described in the former
patents referred to in this specification. The second point of importance which I have
not referred to before is a stop 14 provided for the purpose of arresting the motion
of the cylinder G. This stop 14 is held in a suitable guide formed in the frame A and
is operated by a cam 15 placed upon the axle o. This cam is so shaped that the
stop 14 is thrown out so as to extend below the plate n when it comes opposite to the
plungers R and is withdrawn by the action of the cam in time to allow the next
movement of the cylinder. At each end of the carriage I a finger 16 is fixed. The
end of this finger extends slightly beyond the plungers R and is tapered so that when
the carriage I is thrown forward toward the bar n the tapered ends of the fingers
enter holes made in the bar n so as to hold the said bar stationary in its exact position
ready to receive the plungers R. My correspondent is aware of the English Patent
No. 711 of 1857 in which the lozenges are cut in proximity to the cylinder and make
no claim to such construction. He deems it important that the lozenges be cut at a
distance from the cylinder and that the carrier convey nothing but the lozenges-not
the scrap to the cylinder. When the lozenges are cut in close proximity to
the cylinder the scrap is liable to interfere with the perfect operation of the
machine.
My correspondent is also aware of the patent to Fairlamb and Dunott June 13th

page_text: 1831 in which a spring scraper is used; but said scraper is liable to distort the
crackers and does not deposit them in their proper order on the tray. By arranging
the stationary plate 13 substantially under the axis of the cylinder the lozenges should
any adhere to the plungers, are removed in perfect condition into their proper place
on the carrier.
