Improvements in or relating to Apparatus for the Manufacture of
Sugar-wafers and the like.
I, GEORGE SAMUEL BAKER, of 58, City Road, London, E.C., in the County of
Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to apparatus for the manufacture of sugar-wafers and
similar confections in which an endless chain carrying a series of pairs of
plates or tongs" upon which the wafers are baked is mechanically fed through
a gas oven or other heater, or in which the plates of a series radial to a central
spindle around which they travel are individually rotatable about their own
axes; the object of the present invention is to make such machines more auto-
matic, and to enable them to operate with a much smaller waste or scrap of
batter than in such machines as hitherto usually constructed.
According to this invention an automatic filler or feeding device is provided
for the plates, and also an automatic cutting-off device for getting rid of the
fringe of baked batter which hangs from the meeting edges of each pair of
plates. The cutting-off device may comprise knives provided on all the sides
of one plate in each pair and capable of being operated at the desired intervals
by a cam or other mechanism controlled by some projection on the frame
relatively to which the chain or series of plates has motion. These knives, er
strips employed in place of the knives, may be onerated in passing a stationary
projection to form a bead or edging for each plate whilst the fresh batter is
being delivered on to it and immediately thereafter, so as to enable the batter
to level itself upon the plate filling the corners and being kept from flowing
freely over the edges and subsequently producing waste or scrap.
As an alter-
native to these movable raised edges one of each pair of plates may have a per-
manent bead or edging of such height that only the very small clearance neces-
sary remains between each pair of plates when they are brought together
instead of the excessive clearance which has been provided heretofore.
A convenient construction of automatic filler according to this invention is
a receiver for batter in connection with a cylinder carried on the frame of the
machine and having a piston operated by a cam on the moving plates or on the
chain which carries them or on some part operatively connected with them so
that at the desired intervals a charge of batter is forced from the cylinder into
a device which delivers it on to the surface of a plate beneath it. The cam may
be so shaped or the mechanism it operates so disposed that it will move the
piston to vary the speed at which the batter is delivered on to different portions
of each plate. The device above referred to for discharging the batter on to the
plate should not begin the delivery of batter too soon or complete its delivery
until just before the plates of each pair are closed or brought face to face.
The delivery device may be connected with the cylinder whence it derives its
supply by flexible connections and be arranged to be caught by the travelling

page_text: plate and moved along in company with it during the delivery, against the
action of a spring or other quick-return device and released just before the pair of
plates closes, so as to withdraw the delivery device with a rapid motion.
The cutting-off device in the case of a four-sided plate may comprise knives
one upon each edge of the plate and all connected to constitute a rectangular
sharp-edged band which may be moved to bring the sharp edges up past the
junction of each pair of plates by means of levers pivotted at their ends to the
plate and to the knives and extending across a central cam or eccentric carried
on a shaft having a star-wheel which is turned at the proper intervals as it
passes a stationary projection on the frame.

Improvements in or relating to Apparatus for the Manufacture of
Sugar-wafers and the like.
I, GEORGE SAMUEL BAKER, of 58, City Road, in the County of Middlesex,
Engineer, 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;-
$6
This invention relates to apparatus for the manufacture of sugar-wafers and
similar confections in which an endless chain carrying a series of pairs of
plates or tongs" upon which the wafers are baked is mechanically fed through
a gas oven or other heater, or in which the plates of a series radial to a central
spindle around which they travel are individually rotatable about their own
axes; the object of the present invention is to make such machines more auto-
matic, and to enable them to operate with a much smaller waste or scrap of
katter than in such machines as hitherto usually constructed.
According to this invention an automatic filler or feeding device is provided
for the plates, and also an automatic cutting-off device for getting rid of the
fringe of baked batter which hangs from the meeting edges of each pair of
plates. The cutting-off device may comprise knives provided on all the sides
of one plate in each pair and capable of being operated at the desired intervals
by a cam or other mechanism controlled by some projection on the frame
relatively to which the chain or series of plates has motion. These knives, or
strips employed in place of the knives, may be operated in passing a stationary
projection to form a bead or edging for each plate whilst the fresh batter is
being delivered on to it and immediately thereafter so as to enable the batter
to level itself upon the plate filling the corners and being kept from flowing
freely over the edges and subsequently producing waste or scrap. As an alter-
native to these movable raised edges one of each pair of plates may have a per-
manent bead or edging of such height that no clearance or only a very small
clearance remains between each pair of plates when they are brought together
instead of the excessive clearance which has been provided heretofore.
A convenient construction of automatic filler or feeding device according to
this invention is a pump communicating with a batter supply-reservoir and
having a piston operated at the desired intervals by a cam or otherwise in such
a manner that the requi-ite quantity of batter is forced from the pump, through
a feed-nozzle on to the surface of a plate beneath the latter. The cam may be
arranged to so operate the piston that the speed at which the better is delivered

page_text: Imp18. in or raniny w apparatus for the MTO Duger-wifer
on certain portions of the plate may be varied. The device above referred to
for discharging the batter on to the plate should not begin the delivery of batter
too soon or complete its delivery until just before the plates of each pair are
closed or brought face to face.
The delivery device may be connected with the cylinder whence it derives its
supply, by flexible connections, and be arranged to be caught by the travelling
plate and moved along in company with it against the action of a spring or
other quick-return device. The batter may be delivered not only during the
movement of the delivery device in company with the travelling plate, but also
whilst it moves rearwardly over the plate to its normal position of rest, or during
such rearward movement alone.

Referring first to Figures 1 to 3 the main frame A of the machine has mounted
upon it at one end the driving mechanism comprising fast and loose pulleys B
operatively connected with a train of gear wheels C. Tongs or plates D com-
prising each a lower plate having hinged to it a lid or upper plate are con-
nected by links E so that they form a chain which is made to travel round a
frame A by means of the driving mechanism B C. To enable the chain to
travel freely over the frame A¹, flanged wheels E¹ are provided at the ends of
axles D D. The axles D1 D2 carry the tongs D and also the connecting links E
so that the whole weight of the chain falls upon the flanged wheels E¹ which,
as the chain travels, roll upon the frame. The chain carries the tongs D
through an oven F heated by gas or other means and having a top plate FL and
flue Guide rods D³ ³ carried by supports 14 engage the lids or upper
plates of the travelling tongs 1) as they approach, in such a manner that the
lids are raised upon their hinges d and again lowered whilst their corresponding
lower plates pass under the guide rods. Before the lid is again lowered the
bottom plate of the tongs 1) is automatically charged with batter. To effect
this operation a cylinder G is mounted on a bracket G¹ supported by the frame A
and communicates with a batter supply-reservoir, not shown in the drawings,
by a pipe g and with a feed-nozzle G2 by a pipe gl. A piston having a rod G³
is mounted within the cylinder G and is normally held at the bottom of the same
by a spring g² which bears at one end against a collar g³ on the piston rod at the
other against the head of the cylinder G. On the axle D¹ of each pair of tongs D
is mounted a cam H (Figures 1 to 5) which as it is carried forward by the
travelling tongs D is brought into contact with the end of the piston rod G³. The
end of the piston rod G³ is furnished with a friction-roller g so that it is freely
raised by the approaching cam, and by means of its piston forces a quantity of
batter through the pipe g¹ and feed-nozzle G² on to the lower plate of the tongs D.

page_text: The feed-nozzle G2 comprises a main pipe attached at one end to the pipe g¹
and closed, at the other. This main pipe is supported so as to project over the
lower plate of the travelling tongs D by a carrier or bracket H Fig. 3 and is
provided with a number of small nozzles g³ by which the batter makes its exit
on to the plate of the tongs. The carrier or bracket H' may be either fixed to
the main frame A so that the feed-nozzle G2 is held stationary whilst it delivers
the batter on to the travelling plates or it may be made to travel with each plate
whilst delivering batter and may also be returned in the opposite direction to
that of the travel of the plates, during the time of delivery by means of any
convenient quick-return device. In the latter cases the connection g' between
the cylinder G and the feed-nozzle G2 is made of flexible pipe or tube and the
bracket His carried by a guide H2 upon which it is free to slide in a line
parallel to that traversed by the tongs D. The guide H³ is secured at one end
to the face of the cylinder G and at the other is supported by a bracket H³
secured to the frame A.
On the axle 12 of each of the pairs of tongs D is mounted a bell-crank lever
forming part of the gear employed in moving the feed-nozzle as hereinafter
explained; it is pivotted at J (see Figures 4 and 5) and has arms J1 J2. The
end of the arm J2 is provided with a friction roller J and a spring J keeps the
arm normally raised, the arm J₁ acting against the axle D2 as a stop (Figure 4).
The carrier or bracket H¹ carries an inclined cam-plate H provided at one end
with a recess h (Figure 4) and below and forward of the inclined cam plate H* is
a second inclined cam H fixed to any convenient part of the frame A A¹. The
inclined cams H H are disposed in the same vertical plane as the series of bell-
cranks JJ and operate with the same as hereinafter described.
The carrier H₁ carrying the feed-device G2 and the inclined cam H has
attached a spring or a weight K (Figures 1, 2 and 3) which always tends to keep
it at one end of the guide rod H2.
The trimming device (Figures 6 to 8) for each pair of tongs D comprises four
blades or knives L which may be connected together at their corners as shown
in Figure 7 so that they form one rectangular blade. The blades or knives L
normally remain below the joint of the two plates or tongs 1), but may be
raised and made to pass over the joint at stated intervals by means of the
eccentrics L and operating rods L. The eccentrics L' are mounted on a shaft
carried beneath the lower plate of the tongs D and work within the frames / of
the levers L2. The levers L2 are arranged in pairs each pair being connected
to opposite ends of the rectangular knife band L formed by connecting together
the separate blades or knives L as suggested above. A fulcrum is provided for
the levers L2 by hinging their otherwise free ends to the bottom of the lower
plate 1 by links /. On the shaft upon which the eccentrics L are carried is a
gear wheel L³ and on the frame A' is fixed a rack L' (Figures 1 and 3). As the
tongs pass over the rack L the wheel L³ engages with the rack L which being
provided with the same number of teeth as the wheel L impart one revolution
to the same, and the eccentrics L' being carried round with the wheel L³ raise
and lower the knives L once. The frame A is provided with a second rack L
having half the number of teeth carried by rack L so that as the wheel L³ is
carried over it the wheel receives half a revolution. The knives L are thus
raised by the eccentrics L' and remain in this position until a third rack L
also carried by the frame A¹ is passed over which imparts a second half revolu-
tion to the wheel L³ causing the blades or knives L to be brought back to their
normal position.
The upper plates of the tongs I upon being lowered from the guide rods D³
on to the bottom or lower plates are locked by a catch piece M, (Figures 1, 2, 4
and 5) which passes through a projection Mi in the lid or upper plate and on
receiving a quarter of a revolution locks the upper and lower plates 1) together.
The quarter revolution is imparted to the catch-piece M by a star wheel M
attached to the lower end of the same. The star wheel M2 in passing a pin M³

page_text: conveniently mounted on the frame A is brought into engagement with the
same and is thus made to revolve a quarter of a turn. A similar pin M* un-
locks the plates just before the upper plate enters the guide-rods D³.
The operation of the machine is as follows:-
:-
As the lower plate D approaches a point beneath the feed-nozzle G2 the end
of the arm J2 of the bell crank lever JJ2 with its friction roller J³ strikes
against the recessed end of the cam H and causes the carrier H to which it is
attached to travel forward on the guide H2 against the action of the weight K.
The carrier H carries with it the feed-nozzle G2 the nozzles g of which are kept
directly over the forward end of the lower plate of the tongs D. This forward
movement of the carrier H and its attached parts is continued until the arm J¹
of the bell crank lever J J2 strikes against the end of the lower inclined
cam H³ when the forward movement being continued the arm J2 is forced down
in opposition to the resistance offered by its spring J and released from its
engagement with the recessed end of the inclined cam H*. At this movement
the cam H on the axle D¹ of the adjacent tongs commences to operate the
piston G³ and to force batter from the cylinder through the pipe g¹ and feed-
nozzle G2 on to the lower plate of the tongs D. Whilst the batter is being thus
delivered the bracket H' which carries the feed-nozzle G2 is returning to its
normal position under the influence of the weight K; its speed of return being
regulated by the arm J2 of the bell-crank J J which the inclined cam H* has
to force down, as it returns against the action of the spring J. The inclined
cam H is assisted in forcing down the arm J2 of the bell-crank J1 J2 by the
fixed inclined cam H which, as the bell-crank travels forward with the tongs D,
forces up the arm J and thus lends its aid to depress the arm J2 should the
inclined plane H have difficulty in doing so. From the above it will be
obvious that by adjusting the angles of the inclined cams H4 H5 relatively
to one another and particularly by adjusting the strength of the spring J4 the
speed at which the feed-nozzle G2 is returned may be regulated. A convenient
ratio for the relative speeds of opposite movement of the tongs D) and feed
nozzle G2 is found to be that of 1 to 4. The rate of discharge of batter may be
regulated by the proportions of the cam H and cylinder G, also the cam H may
be so constructed as to vary the speed at which the batter is delivered upon
different portions of the plate D. Just before the feed-nozzle G2 reaches the
end of the plate the cam H passes from under the piston rod G3 which is
immediately returned to its normal position by the spring and the discharge
of batter ceases. As the tongs continue their forward motion the lid or upper
plate D is lowered from the guide rods D' and closed down upon the lower
plate D, and the two plates locked together as above described.
The tongs are then passed through the oven F and no other mechanical
operation takes place until they arrive at the rack L. As they pass over the
rack L the knives L are raised and lowered as hereinbefore described and the
knives by thus passing over the joint of the plates I remove any "scrap" or
baked batter which may protrude from between the same. The tongs D in
passing the pin M are unlocked and the lid or upper plate engaging with the
guide rods D³ is raised upon its hinges d. When the tongs arrive at the top
of the machine the baked batter or wafer is removed and the plates pass on to-
wards the feed-nozzle G². As they pass over the second rack L³ the knives L
are again raised as before described and remain in this position whilst the
plate 1 is being charged with batter from the feed-nozzle G. The batter having
had time to spread, the tongs D arrive over the third rack, Lo, when the knives
or blades L are again lowered to their normal position. The lid or upper plate
is then lowered and locked as before and the same cycle of operations repeated.
Attention is directed to the double purpose to which the knives or blades L
are applied, riz.:-trimming off the scrap" batter and acting as a bead to
the lower plate of the tongs 1) whilst the same is charged with batter. In place

page_text: of this second purpose to which the knives L are put a modified form of lower
plate D may be used having a fixed bead N (Figures 9 and 10). Openings N¹
are provided at the corners of the beading to permit the escape of air when the
lid or upper plate of the tongs D is closed down; these openings enable com-
plete distribution of the batter to occur over the whole interior of the tongs
when they close, for they permit the escape of air which otherwise would check
the flow of batter over the bottom plate when the top plate closes down on it.
The knives L in cases where, as aforesaid, they serve as beads, may have similar
escape-openings cut in them. It is obvious that the automatic feed device
and also the automatic trimming device could both be applied to any wafer
making machine in which the plates or tongs travel. Such a machine for
instance as that described in the Specification of Letters Patent No. 15115 dated
20th November 1886 granted to Joseph Baker and others in which the tongs are
described as revolving round a central vertical shaft each pair of tongs also
revolving upon its own axis, might be provided with either or both of these
devices by arranging the said devices to come into operation between the inter-
vals of the rotation of the tongs upon their own axes.
It will be understood that the above machine may be variously modified both
in its operation and construction. The feed nozzle G2 for instance, may be
arranged to deliver the batter whilst it travels forward with the plate D. To
effect this the feed nozzle would be arranged to travel forward at a slower
pace than the tongs D and might be provided with a quick return device to with-
draw it from between the plates of the tongs immediately before the upper plate
was closed down. Also the plates or tongs might be made in any form to suit
various requirements, the trimming knives being modified to suit the various
forms of plates or tongs.
The apparatus for distributing the batter on the tongs in various quantities
on different parts of the plate may be modified by varying the speed at which the
feed nozzle is returned to its normal position. This might be done by causing
the weight or spring which returns the feed nozzle to act through an eccentric
or link mechanism. As a further improvement the cams which operate the
piston to force out the charge of batter may be adjustable so that the amount
of variation of stroke given to the piston may be adjusted to suit the require-
ments of any particular machine. This would also apply to the mechanism used
for varying the speed at which the feed nozzle would be returned.
In the alternative construction of batter delivery device illustrated in
Figures 11 to 11 a pump cylinder is arranged to move to and fro in slides or
upon guide rods and to accompany each pair of tongs for a portion of their
travel and then to be quickly returned to the starting point. Upon the pump
cylinder approaching the end of a forward movement the pump piston and
cylinder are caused to move relatively with one another to expel the charge of
batter contained in the cylinder. The rearward or return movement of the pump
cylinder along the guide rods is performed by mechanism hereinafter described,
and when approaching the completion of this return movement relative motion
between the piston and pump cylinder again takes place causing suction which
fills the cylinder with batter from a reservoir. The pump is now ready to per-
form an outward movement in company with the next pair of tongs to be charged.
Upon the extremities of the rear axles D2 of the tongs D, are mounted pro-
jecting pieces 13 with teeth De formed upon them for a purpose hereinafter
described. Two brackets G₁ are secured upon the framing A of the machine
and supported between them are guide rods . The pump cylinder G may
be provided with tubular extensions or attachments G7 which slide freely over
the guide rods G The piston of the pump is secured at a point distant from
either end of the piston red which passes through both covers of the pump
cylinder G. A stuffing box Gs is provided in that cover which is in contact
with the batter.

page_text: The brackets G₁ form stops for the extremities G5 G6 of the piston rod to
come against and prevent further movement of the piston whilst the movement
of the pump cylinder G is continued. By this means the pump cylinder Gon
nearing the completion of its forward travel will be moved relatively with the
piston to effect the ejection of the batter and upon nearing the completion of
the rearward travel the cylinder will again be moved relatively with the piston
to effect suction of the batter from a reservoir, through the port R. An
adjustable screw stop G9 may be employed to vary the piston stroke. The for-
ward movement of the cylinder G upon the guide rods is obtained by a projec-
tion D³ upon one of the axles D2 coming into contact with the depending block J
upon the cylinder. The depending block J is capable of being moved up and
down in a slide J upon the pump cylinder G. by means of pins J3 coming into
contact with inclines J2 formed upon the said block J. The pins J3 inwardly
project from an extension A¹ of the framing which is broken away at J Fig. 11.
The inclines and pins are disposed so that at any moment the upper pair shall
not be foul of the lower incline nor the lower pin be foul of the upper incline.
A blade spring may be adapted to bear against the rear of the sliding block so
that after it has been raised by the upper pin it is retained in such raised position
by the pressure exerted by the spring in order that it may clear the upper pin
and also the projecting piece and teeth upon the return movement of the pump
cylinder. Upon the pump nearing the completion of the return movement the
block J is moved down by the engagement of the other pin with the lower
incline, into the path of the succeeding projection D5.
The pump cylinder G requires to be moved rearwardly in a short space of time
in order that the upper plate of the tongs D which is brought down as quickly
as possible after the charge of batter has been deposited, upon the lower plate
shall not foul the discharge pipe. To accomplish this a lever K pivotted to
the frame A is provided upon its boss K³ with a projection K', and teeth K³
(shown in dotted lines) which correspond to and are engaged by the projec-
tions D and teeth D upon the axles D². As the axles move forward a small
rotative movement of the boss is obtained causing the outer end of the lever to
move through an arc and to effect by means of a suitable connecting rod K+,
(broken at K Fig. 11 its continuation and connection at the evlinder being
shown in dotted lines) the quick return movement of the pump cylinder.
The discharge pipe G10 connected at one end to a port in the pump cylinder
is provided at the other end with a number of branches carrying nozzles G2
three only of such branches being shown in Fig. 13. In order to prevent drip
after the discharge has taken place valves G₁ which can be hollowed below as
indicated in dotted lines (Figure 14) may be placed in the nozzles G². The
valves best seen in Figure 14, have stems G12 around which are placed spiral
springs G. When the valves open the springs G¼ exert pressure between
sockets G3 supported by webs in the nozzles, and the nuts and washers upon the
ends of the stems. The valves by these means are again seated immediatelv
the discharge of batter ceases. Other modes of preventing drip may be employed.
The operation of this batter delivering device is as follows:-The pump
cylinder G is moved along the guide rods G to the position shown in Figure 11
by the engagement of one of the projections 15 upon the travelling axles with
the depending block J. In the position shown in the figure, the end of the
piston G has been brought against the bracket-stop G, and the cylinder con-
tinuing its travel moves in relation to the piston which will eject the batter
through the discharge pipe G and nozzles G³. The upper incline upon the
block is now brought in contact with the upper pin J³, which raises the block
out of engagement with the projection D on the axle. At this instant the pro-
jection Kupon the lever K is engaged by another of the projections I³ an 1
causes rotative movement of the boss K³ of the lever, the movement being con-
tinued by the engagement of the teeth D upon the axle D2 with the teeth K

page_text: upon the boss of the lever.
It will thus be seen that a small movement of the
boss K³, causes the end of the lever to move through a large are; this movement
communicated to the cylinder, quickly returns it along the guide rods so that
the plate 1), which is being rapidly closed, does not foul the discharge pipe
carried by the cylinder. As the cylinder nears the end of the return movement,
the end G6, of the piston rod, comes against the adjustable stop G and the
evlinder completing its length of travel again moves in relation to the piston
thereby performing the suction stroke which draws in from the reservoir,
through the port R, a charge of batter for the next pair of tongs. During the
return movement also the descent of the contact block J is effected by the lower
incline coming into contact with the rear pin. The said block J will now be in
the path of the succeeding projection D5 by which it is to be carried forward.
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
