Improvements in Machines for Manufacturing Jujubes and other
Sweetmeats.
I, ANDREW DEAS, of 67 Sydney Street, Glasgow, Engineer, do hereby declare
the nature of this invention to be as follows:-
1
This invention relates to machines for moulding jujubes and, or, stamping or
moulding other confections and it has special reference to that class of such
machines in which a tray containing starch or like material is traversed along a
table, and as it travels it is first passed under a device for stamping out moulds in
the starch and then under a device for casting the semi-fluid or viscous material of
the sweetmeat in these moulds.
In my present invention each mould box or tray is carried by one or more
endless chains or bands, which is or are caused to move forward intermittently by
means of ratchet mechanism fitted at one end of the table or frame. The ratchet
mechanism is driven by suitable levers or connecting rods from a crank or driving
wheel made or fitted on the driving shaft which latter is, or may be, rotated by
power or by hand.
Moulds are stamped in the starch by means of a (or more than one) series of
stamps which is carried by a (or more than one) cross head arranged across the
table of the machine. The cross head has dove-tail pieces at each side which
slide in dove-tail grooves made in two vertical standards, one at each side of the
machine. The dove-tail grooves may be made adjustable by using, at one side of
each groove a sliding piece which can be adjusted by means of a screw or pin.
The cross head is caused to move up and down by means of a cam motion,
consisting of an egg-shaped, preferably grooved, cam driven from a cross shaft.
This cam, as it revolves, pushes up and pulls down a connecting rod fitted or
pinned to the cross-head. There may, if preferred, be two cams fitted on the same
shaft, one at each side of the machine, which work connecting rods at both ends of
the cross-head. The egg-shape formation of the can gives a slow movement
to the stamps when they are just about to make impressions in the starch and when
the impressions are being made they are for a inoment stationary but a quick
movement is given to them when they are being lifted up.
A "knocker" for vibrating the stamps slightly when they are in the starch is
or may be provided. This "knocker" consists of a bell crank lever one arm of
which projects out horizontally and the other down vertically. The horizontal
arm has or may have a hammer shaped end on it which, when the stamps are in
the starch is made to strike a pin or stud on the cross head or its connections and
vibrate it. The vertical arm has or may have a curved lower end provided with a
catch at its extremity. This catch is normally held just below or in engagement
with a pin projecting out from the side of the frame, but, when the stamps are
about to leave the starch, a pin or projection on the cam strikes the end of the
lever and disengages the catch thereby vibrating said stamps. The curved end
of the lever may be made of spring steel.
Fitted preferably on an arm or bracket projecting out from one of the standards,
is the dropper actuating mechanism. This mechanism consists of a screw which
passes through a nut on the said arm or bracket and is capable of vertical
adjustment. Fitted at the lower end of this screw is a crank from the underside
of which projects a pin. This pin, so long as the dropping mechanism is in
operation, strikes on, at each fall of the stamping cross-head, a spring pin which
projects up through a plate extending across the machine. The plate is capable

page_text: of sliding in dove-tail or other guides fitted at each side of the machine. The
lower end of the spring pin projects down through the bottom of this sliding
plate and rests on one end of a lever fulcrumed at or about its centre to the side
of the machine framing. This lever is, at its other end, connected, by a rod (or
rods) to the cross head carrying the dropper spindles. With this arrangement
when the stamping cross head rises the adjustable screw rises with it and the
dropper spindles by their own weight or by the action of a spring fall down and
close the valve boles in the bottom of the dropper tin (hereinafter referred to).
When the stamping cross-head falls the screw strikes on the spring pin and forces
it and its end of the dropper actuating lever downwards, thereby raising the other
end of the lever and the dropper spindles and allowing some of the viscous or
seni-fluid sweetmeat in the dropper tin to fall through the holes into the moulds
in the starch tray.
To throw the dropping mechanism out of gear all that is necessary is to turn
the screw, by means of a short handle, and move its cranked part so that when the
cross-head falls said screw will not strike on the spring pin.
In order to prevent the dropper acting when there is no board under it or
when an edge of the board is just below the dropper holes, a cross shaft having a
cam on it is provided. This cam has a zig-zag groove cut in it and into this
groove a pin or stud on the aforesaid sliding plate works. Fitted also on the
shaft is a star wheel. Stops or catches are also fitted on or between the travelling
chains of which there are preferably three. The arrangement is such, that,
when the front of the board comes over the star wheel, a stop on the chain
catches said wheel and turns it through a quarter of a revolution, and, of course,
at the same time, turns the zig-zag cam. The movement of the cam causes the
pin and sliding plate to move laterally either in or out. When it is moved
inwards the actuating pin for the dropper lever is withdrawn from under the screw,
and, as a consequence, the dropper is thrown out of action. When the plate is
moved outwards the pin is again moved under the screw and the dropper is again
thrown into action.
The movement of the cum and plate may be reversed.
The dropper tin may be made or divided into two or more parts having a series
of holes or valves at the bottom. Spindles carried ou a cross-head and
reciprocated up and down by the movements of the aforesaid dropper lever, open
and close said holes or valves. The tin may have a steam jacket surrounding it.
When two divisions are used in the tin, or when a double tin is used, one for a
different mixture to that in the other, and, when, as in the case of making
fondants, it is necessary to open the valves in one tin before or after those in the
other. Then it is necessary to have two sets of independently acting dropper
spindles, one set operated by the cam mechanisin aforesaid and the other set by a
second zig-zag cam. This second cam may be fitted on a sleeve carried at the
opposite end of the cross shaft to the first cam. The sleeve has also a star wheel
on it for actuating the cam. Additional stops or catches are male or fitted on or
between the chains either in advance of or behind the others according as it is
desired to actuate the second set of dropper spindles either in advance of or
behind the other set. There would also, preferably, be two sliding plates one for.
each set of cam niechanism and these plates would throw into and out of gear
dropper actuating screws and levers fitted at each side of the machine.
Springs may be used to retain the star wheels in position.
The stamp cross-head is provided with a (or more than one) downwardly
projecting knife or plate to retain the starch in position when being stamped and
if necessary to divide off the rows of moulds.
The starch boards instead of being fed into the machine by hand as usual, are,
preferably, fed in continuously by means of suitable mechanism fitted on the
inachine. The mechanism may consist of four pillars or standards, two at each
side of the machine. Each pair of pillars carries two longitudinal shafts having
chain wheels at their ends. One shaft is fitted at the top and the other at the

page_text: bottom. Over the wheels endless chains run and these chains have angled pieces
of metal secured to them. The boards to be fed to the machine are supported in
tiers on the angled pieces, and, of course, as the chains revolve they are lowered
down gradually. When the lowest board of the series arrives at the level of the
table it is deposited on guides or slides and a catch on the longitudinal carrying
chains of the machine immediately catches and pushes it forward to the stamping
and dropping mechanism. As fast as one board is fed forward, another one, in its
turn, is lowered and fed forward. New boards are placed on top of the tier as
fast as those below are fed forward.
In order that the boards may be fed forward at the proper intervals a pawl and
ratchet mechanism is fitted in the machine. This mechanism is actuated at the
proper intervals by means of a lever which has a roller at its end and as the front
of the board travels forward it pushes up said roller and moves the lever so that a
pawl on it is drawn over the teeth of the ratchet wheel. When the board has
passed from under the roller the lever is drawn back by a spring or weight and in
returning to its position the pawl is made to turn the ratchet and with
it a cross shaft having bevel gearing which operates the chains carrying the
boards. The lever action may, if so desired, be reversed.
A handle may be
fitted on the lever.
A suitable stop or catch would be provided for preventing the boards moving
except at the proper times.
If desired the board feeding mechanism may be operated by pinion gear driven
by a star wheel or its equivalent on a cross-shaft.
The dropper and stamp mechanisms may be operated by the boards instead of
by the chains if so desired.
The dropper mechanism may be operated by a train of pinions.
The zig-zag cams may be made with partly straight and partly oblique grooves
so as to give intervals of rest, at the straight parts, to the sliding plate or plates.
The intervals of rest correspond to the intervals between the boards as they are
fed forward.
The dropper spindles may be squared at their upper ends and be passed through
square holes in the cross-head. A thumb nut screwed on to the upper ends of the
spindles may be used to adjust them vertically so as to regulate the amount of
sweetmeat escaping through the holes in the tin.
Two or more sets of stamps may be used and also if desired more than two sets
of droppers and dropping mechanism may be employed.
The apparatus may be modified in details of construction.

Improvements in Machines for Manufacturing Jujubes and other
Sweetmeats.
1, ANDREW DEAS of 67 Sydney Street, Glasgow, 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 stateinent :—
This invention relates to machines for moulding jujubes and, or, stamping or
moulding other confections and it has special reference to that class of such
machines in which a tray containing starch or like material is traversed along a
table, and, as it travels, it is first passed under a device for stamping out moulds in
the starch and then under a device for casting the semi-fluid or viscous material of
the sweetmeat in these moulds.

page_text: And in order that my said invention may be properly understood I have hereunto
appended two explanatory sheets of drawings, whereon,
Fig. 1 is a side elevation of the machine, and
Fig. 2 is a plan.
Figs. 3, 34, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 134, 14, 15, 16 17 and 18 are
detail views.
Referring to the drawings whereon the same reference numerals, wherever
repeated, indicate the same parts:-
In my present invention, which is a development of my prior invention No. 10,890
of 1893, each mould box or tray 1 (see dotted lines Fig. 2) is carried by one or
more, preferably three, endless bands or chains 2, which are caused to move forward
intermittently by means of the pawl and ratchet mechanism 3, fitted at one end of
the table or frame 4 of the machine. The ratchet mechanism is driven by means
of a connecting rod 5, from a disc wheel 6, or a crank, fitted on one end of the
driving shaft 7, which latter is driven by belt pulleys 8 or by hand. 6° are adjustment
slots in the disc wheel.
Moulds are stamped in the starch by means of a (or more than one) series of
stamps or dies 9 (Figs. 13 and 134) which is carried by a board 10ª fitted to a
crosshead 10 (see also enlarged view Fig. 17) arranged across the table of the
machine by means of screws 10. This crosshead has dovetail guide pieces 11 at
each side which slide in dovetail grooves 12 made in two vertical standards 13, oue
at each side of the machine. The dovetail grooves may be made adjustable by
using, at one side of each groove, a sliding piece 14 which can be adjusted by means
of screws 15 as in my prior invention aforesaid.
The crosshead 10 is caused to move up and down by means of a cam motion,
consisting of an egg shaped cam 16 fitted on the driving cross shaft 7.
This cam,
as shown more particularly at Figs. 10 and 11, has a groove 17 in it in which works
a pin 18 on the lower end of a connecting rod 19, which, at its upper end, is pinned
to the sliding guide pieces 11 of the crosshead 10. If preferred a second cam 16°
may be fitted at the opposite end of the shaft to work a connecting rod not
shown at the other end of the crosshead. The shape of the cam is such that a
slow movement is given to the stamps when they are just about to make impressions
in the starch, whilst, when the impressions are being made, they are caused to
remain stationary for a moment, but, when they are being raised, a slow movement
is first given to them and then a quick upward movement.
20 are spiral springs, which, at their upper ends, are connected to pins 21 fitted
in the guide standards 13, and, at their lower ends, to the connecting rods 19.
These springs steady the motion of the crosshead.
A "knocker" for vibrating the stamps slightly when they are in the starch is
provided. This "knocker" consists of a jointed bell crank lever one arm 22 of
which projects out horizontally and the other 23 up vertically (see Figs. 1, 2
and 17). The vertical arm 23 is pinned to a cross shaft 24 and the horizontal
arm 22 which is connected to the arm 23 by a spring 27 is provided with a catch 25
arranged to normally engage with a pin 26 in the standard 13. A bell crank lever
and its connections is also fitted at the opposite side of the machine. A hammer 28
is rigidly pinned to the centre of the shaft 24. When the stamps are near the
bottom of their stroke pawls 29, one at each side of the machine, strikes the heads
of the catches 25 and force them out of engagement with the pins 26 thereby
causing the hammer 28 to strike the upper side of the crosshead 10 and vibrate the
stamps so as to free them from the starch. The hammer is raised again by the
upward movement of the crosshead, and, as a consequence, the catches 25 override
the pins 26 and resume their former positions ready for the next down stroke of
the pawls 29.
Fitted on au arm 30 projecting out from one end of the crosshead is the dropper
actuating mechanism for the tin 48. This mechanism consists of a screw 31 (see
enlarged view Fig. 16) which passes through an adjustable nut 32 fitted in a
bridge 34 on the arm 30. A milled edge collar 33 is provided for turning the

page_text: nut 32. 35 is a collar carried in the arın 30 and feathered to the screw 31, it has
a projecting handle or lever 35º.
Fitted at the lower end of the screw is a crank 36 from the underside of which
a pin 37 projects. This pin, so long as the dropping mechanism is in operation
strikes on, at each fall of the stamping crosshead, a pin 38 which projects up
through a plate 39 extending partially across the machine. This plate is capable
of sliding in dovetail guides 40 on the side of the machine. The lower end of the
pin 38 projects down through the plate 39 and rests on one en of a lever 41,
fulcrumed at 42 on a cross shaft 43 carried in the framing. The other end of the
lever is connected by the rod 44 to the crosshead 45 carrying the dropper spin lles 50.
46 is the hopper for the semi-fluid material to be "dropped" or cast, as will be
seen, it may be divided by a partition 47 into two compartments 48, 49 for different
materials. With this arrangement when the stamping crosshead 10 rises, by the
action of the cam 16, the adjustable screw 31 rises with it and the dropper spindles 50
by their own weight (or by the action of a spring if preferred) fall down and close
the valve holes in the bottom of the dropper tin 48. When the stamping
crosshead falls the screw 31 strikes on the pin 38 and forces it and its end of
the dropper actuating lever 41 downwards thereby raising the other end of the
lever and the dropper spindles 50 and allowing some of the viscous or semi-fluid
sweetmeat in the tin 48 to fall through the valve holes into the moulds in the starch
tray.
To throw the dropping mechanism out of gear all that is necessary is to turn the
lever 35 together with the screw 31 and its cranked part 36 so that, when the
crosshead falls, the pin 37 will not strike on the pin 38.
In order to prevent the dropper acting when there is no board under it, or
when an edge of the board is just below the dropper holes, a cross shaft 51 having
a cam 52 on its sleeve 52 is provided (see enlarged view Fig. 3). This cam has
a zig-zag groove 53 cut in its surface and into this groove a pin 54 (shown in dotted
lines) on the sliding plate 39 works. Fitted also on the sleeve 52° is a star
wheel 55 (sec also detail view Fig. 3A). Catches 56, 56" (see also detail side and
plan views Figs. 7 and 8) are fitted at the proper intervals apart between or on the
chains. These catches, as shown, consist of a plate 57 having a projecting catch.
pin 58, two steadying pins 59 aud a rivet pin 60 which is secured to the chain. The
pin 58 may be adjustable in the plate 57. The arrangement is such, that, when the
front of the board comes under the dropper the pin 58, of the first catch 56, on
the chains, catches one of the arms 61 of the star wheel 55 and turns it through a
quarter of a revolution, and, of course, at the same time, turns the sleeve on the
shaft 51, and zig-zag cam 52. The movement of the cam causes its pin and the
sliding plate 39 to move laterally either in or out. When it is moved inwards
the actuating pin 38 for the dropper lever 41, is withdrawn from under the screw
pin 37, and, as a consequence, the dropper is thrown out of gear. When the
plate 39 is moved outwards the pin 38 is again moved under the screw. pin 37 and
the dropper is again thrown into gear. The catches 56 and 56 are so placed on the
chain relatively with the board 1, that the front edge of the board has just cleared
the valve holes in the dropper tin 48, when the first catch 56 comes into operation
and turns the star wheel 55 so as to throw the dropper mechanism into gear, whilst
the second catch 56° only comes into operation and throws the dropper mechanism
out of gear again when the back edge of the board is just coming under the
dropper valve holes. In this manner the fluid is prevented from dropping on the
edges of the board. Pairs of catches 56 and 56 are arranged at intervals all along
the chain so as to suit a number of boards, travelling in succession and to throw the
dropper mechanism into and out of action at the proper times. 62 are catches
fitted at intervals on the centre chain for feeding forward the boards. Figs. 14
and 15 show one of these catches in side and plan view, as will be seen it is secured
to the chain by a pin 63. 64 is a pin which rests on the chain.
When two dropper tins are used or a single tin is, as shown, divided into two

page_text: compartments 48 and 49 for different materials, and, when, as in the case of making
fondants, it is necessary to open the valves in one tin before or after those in the
other, then it is necessary to have two sets of independently acting dropper spindles,
one set operated by the cam 52 as aforesaid and the other by a second zig-zag
cam 52 (see Fig. 3). This cam which is of the same construction as the cam 52
is fitted on a sleeve 52, at the opposite end of the cross shaft 51. This sleeve has
also a star wheel 55, on it for actuating the cam 52. Additional stops or
ratches 56, 56, are fitted on one of the chains either in advance of or behind the
others according as it is desired to actunte the second set of dropper spindles either
in advance of or behind the other set. On the drawing Fig. 2 the catches are
shown slightly behind the first set. There is also provided on the opposite side of
the machine a second sliding plate 39, with its pin 54, a second adjustable
screw 31³, with its crank, and pin not shown, supported on an arm 30º. The
levers 41, 41, for actuating the dropper spindles 50, are, as before stated secured
to the cross shaft 43, whilst the levers 41, 41, for actuating the spindles 50º, are
secured to a sleeve 50", on said shaft (see also Fig. 17).
The action for the second set of spindles is precisely similar to the first set.
On the drawings the cams 52 and 52 are shown as they appear when the
dropping spindles 50, and 50° are both thrown into gear. As will be seen the
two armed lever 41, of the one set is at one side of the machine whilst the two
armed lever 41 of the other set is at the opposite side.
As shown to an enlarged scale at Figs. 13 and 13 the board 10" of the
stamping cross head 10 is provided with one (or more than one) downwardly
projecting knife or plate 65 to retain the starch in position when being stamped,
and, if necessary, to divided off the rows of moulds. The lower edge of the
plate (or plates) may be serrated as shown at Figs. 13 and 13ª.
The starch boards 1 instead of being fed into the machine by hand, as usual,
are fed in continuously by means of suitable mechanism fitted on the machine.
This mechanism consists of four standards or supports 66 two at each side of
the machine. Longitudinal shafts 67, having chain pulleys 68 are carried by
these standards. Two other shafts 69 also having chain pulleys 70, are carried
by brackets 71, bolted to the framing. The endless chains 72 which run on the
pulleys 68, 70, have angled pieces of metal 73 secured to them (see also end view
Fig. 6 and enlarged detail views Figs. 4 and 5). The boards 1 to be fed to the
machine are supported in tiers on the angled pieces 73 (see dotted lines Fig. 6),
and of course, as the chains 72 revolve they are lowered down gradually. When
the lowest board of the series arrives at the level of the table it is deposited on
guides or slides 74 and one of the catches 62 on the chains 2 immediately
catches and pushes it forward to the stamping and dropping mechanism. As
fast as one board is fed forward, another one, in its turn, is lowered and fed
forward. New boards are placed on top of the tier as fast as those below are
fed forward.
In order that the boards 1 may be fed forward at the proper intervals. a pawl
and ratchet mechanism is fitted on the machine. This mechanisin consists, as
shown more particularly at Fig. 12, of an eccentric 75 fitted on the main
driving shaft 7, of the machine aud which has a jointed eccentric rod 76. This
rod is pinned to the long arm of a lever 77 fulcrumed loosely on the cross
shaft 78 and whose short arm has a pawl 81 on it. This pawl 81 works in the
teeth of a ratchet wheel 80 having also bevelled teeth which gear with a bevelled
pinion 79 on the shaft 69. A bevelled wheel 82 is also fitted at the opposite
end of the shaft 78 and this wheel gears with a piniou 83 on the other shaft 69.
This mechanism is actuated at the proper times by means of a lever 84, having a
beavy roller 85 at its end (see enlarged side view Fig. 9) and which is fulcrumed
at 86 to a bracket 87 on the frame. 88 is the lever handle, 89, 89* two catches on
the lever 84. 90 is a wheel mounted on the shaft 69 and having preferably five
teeth. 92 is a bar to which the lever 84 can be locked when necessary by a pin 93.

page_text: 94 is a spring which normally tends to so pull the lever 77 as to turn the ratchet
wheel 80 and the cross shaft 78 and thereby lower the boards. The whole
arrangement is such that as the front of the first board travels forward it pushes
up the roller 85 and moves the lever 84 sufficiently to raise its catch 89 above and
clear of one of the teeth of the wheel 90 and at the same time allows the shaft 69
to perform, under the action of the spring 94 and pawl and ratchet 80, 81, the
slight movement necessary to bring the tooth 95 out from underneath and free of
the catch 89. Further movement of the wheel 90 is prevented by the other
catcb 89 of the lever catching against the tooth 96.
When the first board has
passed from under the roller 85 the lever 84 is drawn back to its former position
(as at Fig. 9) by the weight of the heavy roller 85, or by means of a spring if so
preferred, and, in being so drawn back the tooth 96 is released so that the
wheel 90 and shaft 69 can, under the action of spring 94 perform a partial
revolution until the tooth 97 is caught by the catch 89. This partial revolution
of the shaft gives sufficient motion to the bevel wheels 80, 82, pinions 79, 83,
and chains 72 as to lower a second board on to the travelling chains 2 and
table 74. When the second board travels forward it actuates the lever 84 so as
to feed a third board and so on each board automatically operating the mechanism
so as to feed the next succeeding one. It is necessary in order to start the feeding
of the boards to press down the handle 88 until the tooth on wheel 90 for the
time being caught by the catch 89 is released.
The eccentric rod 76 (Fig. 12) is made in two parts 76, 76 one of which has
a slot 76° and the other studs 76d passing through the slot 76°. These parts have
a sliding movement on one another limited by the length of the slot 76. The
spring 94, as shown, is attached to the part 76. The object of this arrangement
is to allow the eccentric 75, which is on the main shaft 7, to revolve without
actuating the lever 77 and pawl 81 and turning the ratchet 80. This ratchet is
turned by the action of the spring 94 alone. When the spring is in the position
shown at Fig. 12 it tends to pull the lever and turn the ratchet round but it is
prevented from doing so until the proper times by the escapement mechanism
Fig. 9. Whenever said escapement mechanism allows the ratchet wheel to turn,
the spring 94 which, as shown, is at tension, exerts its influence and turns the
ratchet wheel, and, in so doing, comes into compression. The spring is again
brought into a state of tension by the action of the eccentric.
Owing to the sliding movement of the parts 76, 76 on one another the action
of the eccentric 75 does not affect the mechanism any further than to bring the
lever 77 and spring 94 into their original position after each compression of said
spring.
When the lever 84 is locked by means of the pin 93 the board feeding mechanism
is stopped.
As shown at Figs. 6, 4 and 5 the angled pieces are so made and pivotted to the
chains 72 that when passing over the top pulleys 68, 68, they fall over ready to
receive the boards 1. The backing piece 98 bears against the chain 72 and holds.
the angled piece 73 in proper position for the reception of the boards.
In order to retain and steady the star wheels 55, 55b in position, indented
squares 99 may be fitted on the sleeves 52", 52. A spring 100 fitted at each side
of the frame rests on each square and steadys it in position (see detail view Fig. 3).
The dotted lines Fig. 3B show the square as it appears when being turned round.
The stamps are prevented from coming down on the wooden beadings or edges.
constituting the ends of the trays by means of bell cranks 101 and wires 102 as in
my prior invention aforesaid.
When a double set of droppers is used as at Figs. 1 and 2, the levers 35*, would
be preferably connected by a cross bar 103.
The receptacle shown in dotted lines at 104 Fig. 1 is for an auxiliary supply of
the sweetmeat, which can be drawn off into the hopper by means of a cock 105.
Of course in the case of only one hopper and a single set of dropper valves only
one set of dropper actuating mechanism would be required.

page_text: The "knocker" actuating mechanism may be single and only at one side of the
machine if so desired.
The hopper with the double row of spindle valves could, as is evident, be driven
by one set of dropper actuating mechanism and be made to drop two rows at a
time.
The hopper is or may be enclosed by a jacket or casing into which steam is
admitted.
The stamps may be adjusted vertically by the butterfly nuts 105 on the
crosshead 10.
If desired the board feeding mechanism may be operated by pinion gear driven
by a star wheel or its equivalent on a cross shaft.
The dropper and stamp mechanisms may be operated by the boards instead of
by the chains if so desired.
The dropper mechanism may be operated by a train of pinions.
The zig-zag cams may be made with grooves partly straight and partly oblique
(as shown in Mercator's projection at Fig. 18) so as to give intervals of rest, at the
straight parts, to the sliding plate or plates. The intervals of rest correspond to
the intervals between the boards as they are fed forward.
The dropper spindles may be squared at their upper ends and be passed through
square holes in the cross head. Thumb nuts screwed on to the upper ends of the
spindles may be used to adjust them vertically so as to regulate the amount of
sweetmeat escaping through the holes in the tin.
Two or more sets of stamps may be used and also if desired more than two sets
of droppers and dropping mechanism may be employed. .
The apparatus may be modified in details of construction.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
consider novel and desire to claim is :-
1. The general arrangement and combination of the parts of the machine,
