A New or Improved Machine for the Manufacture of Gum Lozenges
and other like Articles.
1, JOSEPH GELDER of 58 Arlington Street, Salford, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a means of producing gum lozenges and other like
articles, and the object of this invention is to employ a machine for the purpose of
filling the compound into the moulds that have been previously formed on trays in
the ordinary manner, in lieu of filling each mould separately by hand.
I attain this object by the means hereinafter described and as illustrated in the
accompanying sheet of drawings in which
Fig. 1, is a plan view of a machine constructed according to this invention, and
Fig. 2 is a side view of a part of the same machine.
In the manufacture of gum lozenges and like articles by the means ordinarily
employed, trays are filled with some suitable powdered substance such as ground
starch, and the moulds are impressed therein by blocks which leave impressions of
the shape and size required, in the aforesaid powdered substance; the liquid
compound is then poured from a ladle by hand into the moulds successively.
In this invention I construct a frame such as a on which to rest a tray or trays b
that contain the moulds which have been prepared in the manner herein before
described.
In order to fill these moulds, I place a trough c supported in a transverse
position by brackets e, the bottom of said trough being provided with holes f
of a suitable size over which I place a plate d in which are corresponding holes,
said plate being free to slide on the bottom of the trough so as to open and
close the holes therein. I place a shaft g at one end of the machine with either
a hand wheel or fast and loose pulleys and fitted thereon.
At the opposite end of this shaft I place an eccentric j', which imparts motion
to the mechanism that is applied for working the tray b backwards and forwards
on the frame a under the trough c, and also opening and closing the holes f in said
trough.
I effect these movements by means of a combination of rods and levers connected
with the shaft g and the toothed wheel gearing. g, h and j: on the spindle k carrying
the toothed wheel j, I place two ratchet wheels and m in reverse positions and
attach to the swivel bracket n by means of the arms n' and n² the ratchets /¹
and m'.
The aforesaid swivel bracket n is connected at n³ to the eccentric ; by means
of the rod ex, and to the stopping and reversing gear p by means of the rod d*.

In order that the tray may move towards the end B, the eccentric o causes
the ratchet wheel to revolve the wheel j, and thereby actuate the shaft g' and
the wheels g and y, by these means moving the tray b and at the same time

the holes in the trough are covered with the blank portion of the plate d, and
the liquid compound is stopped from running out on to the tray during the time
that the division spaces between the rows of moulds are passing along under the
trough c. When the next row of moulds comes under the holes f, the bevelled
end of the stud r will be caused to enter the succeeding notch q' by means
of the springs, thereby withdrawing the plate d sufficiently to permit the holes
in said plate to come over the holes in the bottom of the trough, when the
moulds will be filled as will also each succeeding row of moulds in like manner.
When the tray has reached the end B of the frame, the stud t will come in
contact with the stop u, which will cause the catch u' to be pushed into the middle
notch p² which will thereby thrust the rod v backward; said rod is attached to
the plate whaving a groove w' formed therein in which is inserted a stud. 12

lifted out of action and stopping the machine. When another tray of moulds
has been placed on the frame in lieu of the tray that has been filled, the
machine is restarted by the operator placing the catch u into the notch at the
opposite end of the lever p thereby causing the ratchet m¹ to fall into the teeth
of the ratchet wheel m, and the tray c will then commence to travel towards the
opposite end D, where it will be stopped in the manner herein before described by:
the catch t¹ coming in contact with the stop u².

A New or Improved Machine for the Manufacture of Gum Lozenges
and other like Articles.
I, JOSEPH GELDER, of 58 Arlington Street, Salford, in the County of
Lancaster, 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:―
This invention relates to a means of producing gum lozenges and other articles,
that are required to be filled either into moulds or boxes, and the object of this
invention is to employ a machine for the purpose of filling the compound into the
moulds that have been previously formed on trays in the ordinary manner, or into
boxes placed on said trays, in lieu of filling each mould or box separately by
hand.
I attain this object by the means hereinafter described and as illustrated in the
accompanying four sheets of drawings, in which
Fig. 1 is a plan view of a machine constructed according to this invention, Fig. 2
is a side view, and Fig. 3 is partly an end view and partly a transverse section
through line C C, in Fig. 1 of the same machine.
Figs. 4, 5 and 6 represent the mechanism, drawn to an enlarged scale, which is
employed for stopping and reversing the machine.
In the manufacture of lozenges and articles of a like nature, by the means
ordinarily employed, travs are filled with some suitable powdered substance such as
ground starch, and the moulds are impressed therein by blocks which leave
impressions of the shape and size required in the aforesaid powdered substance ;
the liquid compound is then poured from a ladle by hand into the moulds
successively.
1.
In this invention, I construct a frame such as a with a sliding plate 6 on which
to rest a tray or trays that contain the moulds which have been prepared in the

page_text: manner herein before described for lozenges, or boxes placed in successive order for
the purpose of being filled with plastic substances.
The aforesaid sliding plate is supported by brackets b', which slide on the guide
rails 6, placed at either side of the frame, and said plate is thereby capable of
being moved towards either end of the frame.
In order to fill the aforesaid moulds or boxes, I place a trough c supported in a
transverse position over the plate b, by means of the brackets e that are attached
to each side of the frame a.
I form the bottom of the trough c, with holes f of a suitable size at a convenient
distance apart, over which I place a plate d in which are corresponding holes, said
plate being free to slide in the bottom of the trough so as to open and close the
holes therein.
I place a shaft g² at one end of the machine with either a hand wheel or fast and
loose pulleys h¹ and h² fitted thereon as shown.
At the opposite end of this shaft I place an eccentric j', by which, motion is
imparted to the mechanism that is employed for moving the plate 6 on which the
moulds or boxes are placed, backwards and forwards on the frame a under the
trough c, and also opening and closing the holes fin said trough.
I effect these movements by means of the combination of rods and levers
connected with the shaft g², and the toothed wheel gearing g, h, and j in the manner
I now describe.
I connect the eccentric by means of the rod ex on plan, to the forked lever or
swivel bracket n, which is fitted on the spindle kon which the toothed wheel j.is
also carried; I place two ratchet wheels and m in reverse positions on the afore-
said spindle k, and attach the ratchets land m' to the arms n' and n² of the swivel
bracket or lever n, by means of the studs n³ and n'. The ratchets l' and m¹ are
respectively brought into contact with the teeth of the ratchet wheels. I and m, or
lifted therefrom by the action of the plate w, which is shown drawn to an enlarged
scale in Figs. 4, 5, and 6, said plate having a groove w¹ formed therein, for receiving
the studs n and no, that are attached to the free ends of the ratchets l' and m' and
slide in said groove.
I connect the swivel bracket n to the stopping and reversing gear bracket p, by
means of the rod d*, and said bracket p is fitted loosely at its lower end on the
stud u that is attached to the frame a.
The lever is connected at its lower end to the aforesaid gear bracket p, by the
stud 2, and the upper end of said lever to the plate w by the connecting rod v.
The Tshaped head of the bracket p has ✓ grooves, u¹, u², and u³, formed on
the inner side thereof for receiving a corresponding projection on the lever t'; when
the lever t is resting in the centre groove u², the relative position of the ratchets /
and m' with the plate w will be. as shown in Fig. 4, both of said ratchets being
thereby lifted free from the ratchet wheels and m and the machine stopped,
although the driving shaft 92, and the gear connected with it will continue in
action.
The plate b is moved along the frame a by means of the toothed wheel
fitted on
the shaft g', said toothed wheel gearing into the rack y' that is attached to the
underside of the plate b.
The shaft g' is actuated by the pinion g in combination with the gear wheels h
and j.
When the plate is at the end A and has had the moulds or boxes placed thereon
ready for filling, the lever t is moved by hand, from the centre V groove ², into
the V groove which thereby places the plate wo in the position shown in Fig. 5
causing the ratchet to engage with the teeth of the ratchet wheel 1, each
revolution of the eccentric j' moving said ratchet one tooth forward and imparting
a corresponding motion through the gear wheels j, h, and g to the plate b.
By these means a row of moulds or boxes are placed in position under the row of
holes, at the same time the wheel g-which is fitted on the shaft gl-is revolved,
and the bowl that is connected to one end of the sliding plate d, is forced out of the

page_text: recess on to the plain portion of the face of said wheel 9 thereby sliding back the
plate d and opening the holes f, until the next recess q' comes opposite the aforesaid
bowl into which said bowl is caused to enter by the pressure of the spring r²,
Fig. 3, when the holes are again closed, and cut off the supply from the trough c
until the next row of moulds or boxes have reached their position under the aforesaid
holes f.
This operation is repeated until the tray b reaches the end of the frame a and the
whole of the moulds or boxes have been filled, when the projection t¹ comes in
contact with the stop attached to the lever t', causing said lever to be moved from
the V groove u back into the centre 'V groove u² which thereby lifts the ratchet l¹ so
as to be out of contact with the ratchet wheel as shown in Fig. 4, and as herein
previously described.
The moulds or boxes that have been filled having been removed from the tray b,
and replaced by others requiring to be filled as before, the lever t is moved over to
the V groove u' which places the ratchet m' in contact with the teeth of the ratchet
wheel m by altering the plate w to the position shown in Fig. 6, when the plate b
will commence to move back towards the end A of the machine, the operation of
filling the moulds or boxes being the same as herein previously described. When
the tray has travelled to within a short distance of the end A of the frame, the
projection t¹ comes in contact with the raised end t of the sliding rod to, which is
thereby drawn along until when the last row of moulds or boxes has been filled, the
raised end t of aforesaid sliding rod comes in contact with the stop t, which moves
the lever back into the centre V groove u thereby lifting the ratchet m¹ out of
contact with the teeth of the ratchet wheel in the manner herein previously
described, and as shown in Fig. 4; the mechanism that is connected with the
eccentric continuing in motion but being inoperative until the lever is again
moved from the centre V groove.
The trough c is steam jacketted in order to keep the gelatinous compound in a
fluid state; steam may be passed into the casing of the trough and emitted therefrom
by means of the pipes x.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1st. A machine with a travelling plate on which to place moulds or boxes,
for passing under a trough containing the compound required for filling said
Fmoulds or boxes, and actuated by mechanism in the manner substantially as herein
. before described.
2nd. In a machine with a travelling plate on which to place moulds or boxes
for passing under a trough containing the compound required for filling said moulds
or boxes, the use of stopping and reversing motion substantially as herein before
-described, and as shown in Figs. 4, 5 and 6.
