tioner, and HARRY DOBSON JACOBSON, of 13, Hope Street, Wholesale Confectioner.
all in Liverpool, in the County of Lancaster, do hereby declare the nature of
this invention to be as follows:-
This invention has for its object an improved machine for parcelling or wrap-
ping objects in paper or other fabric. It is designed more especially for wrap-
ping caramels, but other objects such as squares of soap, blacklead, or the like,
may be wrapped. We will use the term caramel for convenience. We are
aware that machines have been designed with a similar object to that indicated
above, but we consider that our machine is more compact and simple, and
reduces the number of movements hitherto usual.
We provide a table having a slot therein, and this slot is continued down-
wards somewhat in the form of a rectangular tube cut away in parts. Below
the table and adjacent to the sides of the tube are arranged folding devices,
which come automatically into operation when desired, and above the slot is
provided a reciprocating plunger with a vertical movement.
The paper in which the caramels are to be wrapped is either placed by hand
upon the table in suitably shaped pieces, or it is fed from a roll, and sheared
off intermittently by a reciprocating knife. The caramels are fed by hand onto
the table, or if desired we may employ mechanical feeding.
All the moving parts are preferably driven primarily off one shaft, and counter
shafts (positively geared thereto, and provided with cam races or equivalent
mechanism) actuate the folding devices at the proper moment.
In action a piece of paper is placed over the slot (which is temporarily bridged
over by light retractile flaps), and a caramel is placed centrally thereon. The
plunger, hitherto raised, now descends, and drives the caramel down the tube
carrying with it the piece of paper, which latter is folded up on two sides by
the sides of the said tube.
The plunger then withdraws, and the upstanding edges of the paper are
folded over onto the top of the caramel at each side in succession by means of
a pair of folding wings pivotted horizontally on a level with the top edge of
the caramel.
Each folding wing has extended portions at each end, and the said extended
portions are positively affixed to the wing spindle, while the central portions
are mounted free on said spindles and are free to revolve with relation thereto.
but tend to turn when said spindles are rotated by reason of being coupled
thereto by light springs. When the central portion of the wing folds the paper
down it rests thereon, and, its spindle continuing to rotate, the side extended
portions sweep over the extreme ends of the caramel and carry with them the

page_text: paper which projects over, and they thus make the end folds or tucks at one
side. The wing folder as a whole then withdraws and the other one fulfils
similar functions at the other side.
Four vertically pivotted leaves next swing flat against the ends of the
caramel, (two at a time at opposite ends) and this completes the penultimate
stage. The projecting piece of paper at each end is turned up by the further
downward movement of the caramel in the tube, this motion being caused by
the pressure of the next descending caramel.

We, THOMAS MUNDY TRIPP, of 21, Berkley Street, Cardboard Box Maker,
PERCY ISIDORE JACOBSON, of 195, Upper Parliament Street, Wholesale Confec-
tioner, and HARRY DOBSON JACOBSON, of 13, Hope Street, Wholesale Confectioner,
all in Liverpool, in the County of Lancaster, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be parti-
cularly described and ascertained in and by the following statement:-
This invention has for its object an improved machine for parcelling or wrap-
ping objects in paper or other fabric. It is designed more especially for wrap-
ring caramels, but other objects, such as squares of soap, blacklead, or the like,
may be wrapped. We will use the term caramel for convenience. We are
aware that machines have been designed with a similar object to that indicated
above, but we consider that our machine is more compact and simple, and
reduces the number of movements hitherto usual.
The caramel is placed by hand (or it may be fed by machinery, but this
forms no part of our invention) upon a table with the paper beneath it, and a
plunger descending upon it carries it downwards through a slot therein, and
thus turns up the paper at each side. The plunger then withdraws, and im-
mmediately thereafter folding devices come into operation and turn the paper
over onto the top and downwards against the ends. Other folders then con-
tinue the end tucks and on withdrawing leave a projecting tongue at each end.
The next caramel is then carried down by the plunger and this causes a still
further descent of the first named down a chute of approximately the same
area as the caramel bottom, thereby completing the folding.

page_text: 1 shows the sides of the frames of the machine, and 2 the table supported
thereon. 3 are upwardly projecting arms carrying guides 4 in which the
plunger rod 5 carrying the plunger reciprocates. The up and down motion of
the plunger 6 is imparted by an arm 7 pivotted at S to a stand 9. A tripping
lever 10 pivotted at 11 to stand 9 is connected by link 12 to arm 7, and when
said tripping lever is depressed (by means of cam 34, as hereafter described)
plunger 6 is depressed and carries with it the caramel A, and, (on with-
drawing) leaves it in the position shown in Fig. 3. A spring 13 ensures the
return of plunger 6 to its topmost position when the tripping lever 10 is released
by its cam. Fig. 11 shows the caramel resting on its paper, and Fig. 12 shows
the paper turned up at both sides by the descent through the slot 14 in table 2.
A pair of light retractile doors 15 (see Fig. 3) normally close slot 14 and are kept
up in place by a pair of light springs 16. The down-ward course of the caramel
is guided on either side by two flaps 17 which form part of what we term the
wing folders. These are clearly shown in Figs. 3, 4, and 5. In Fig. 3 the right
band flap is shown in a horizontal position resting on the top of the caramel A,
but it should be clearly understood that it is not till the plunger has reascended
that said flap assumes this horizontal position, as it normally occupies an up-
right position, similar to and opposite the left hand flap 17.
Each wing folder is mounted on a transverse spindle 18 which is journalled
in the side frames 1 of the machine, and comprises a pair of wings 19 rigidly
attached to said spindle, and a flap 17 between them. free to revolve thereon.
The relative positions of said flap and wings is normally maintained by a spiral
spring 20 as clearly shown in Fig. 4, and the width of flap 17 is about equal
to the length of the caramel A.
When the caramel arrives at the position shown in Fig. 3 and the plunger 6
has reascended, the right hand wing folder 17, 19, is automatically turned by
its spindle (by means hereafter described) and the flap 17 and wings 18 thus
turn over the paper flat on the top thereof, see Fig. 13. The spindle 13 con-
tinuing to rotate leaves the flap 17 resting on the top of the caramel, and the
wings 19 sweep down over the ends of the caramel with a circular motion, until
they arrive at the position shown at the right hand of Fig. 3, and this makes
the end tucks at one side of the caramel; see Fig. 14. The right hand wing
folder then withdraws to its upright position, and immediately thereafter the
left hand wing folder 17, 19, comes into action and fulfils similar functions at
the left hand side. This in turn withdraws and leaves the caramel as seen at
Fig. 15.
The two side plates are connected together inside by a plate 21 which carries
a pair of rectangular guides 22, the adjacent ends of which are placed the width
of the caramel apart and thus form a continuation of the caramel chute. Plate
21 is slotted as shown at 23. The final portion of the caramel chute is formed
of rectangular plates 24. We provide four folders 25 (hereinafter termed doors)
pivotted in the adjacent corners of guides 22, and their function is to close some-
what after the manner of doors, against the ends of the caramel, and thus to
complete the end tucks of the paper. Four corresponding fingers 26 attached
to guides 22 by setscrews 27 are caused at the proper moment (by means here-
after described) to push the doors 25 and thus to bring them into desired posi-
tion, riz., flat against the ends of the caramel. (See dotted lines, Fig. 2.) These
doors are operated in pairs, those at the right hand of the machine we have
illustrated being first actuated. The spindle 28 of each door penetrates the
plate 21, and carries beneath it an arm 29 to which is attached a spring 30
which constantly tends to keep said doors in their inoperative position as shown
in full lines Figs. 2 and 3. It will thus be seen that on the pressure on fin-
gers 26 being eased, doors 25 will at once resume their open position.
When fingers 26 and consequently doors 25 are actuated at one end of the
machine, the paper at one side of the caramel is folded in, as shown at Fig. 16;
the other pair of doors next fold the paper at the other side as shown at Fig. 17.

page_text: By the time this stage is reached another caramel has been placed upon its
paper on the doors 15 of table 2, and the plunger now makes another descent
and brings down the second caramel which takes the place of the previous one,
and drives the latter down that portion of the chute formed by plates 24.
This turns up the projecting tongue of folded paper at each end and thus com-
pletes the folding. See Fig. 18.
It is to be understood that the caramel being operated upon is supported by
those beneath it, the friction against the sides of plates 24 being sufficient to
maintain them. That portion of the chute formed by plates 24 may taper a
little if desired.
We will now describe the means for operating the above described mechanism.
Journalled in the side frames 1, (at 31, Fig. 2) are two transverse shafts 32,
each carrying a toothed wheel 33, and these wheels are positively geared together
in any known manner, for instance by chain gearing or a train of spur gearing.
(Not shown.)
The right hand shaft carries four cams, and the left hand shaft three. These
cams are shown detached, but occupying their proper relative angular positions
in Figs. 6 to 10. Those on the right hand shaft comprise one cam 34, (shown
also in dotted lines in Fig. 1,) for depressing the tripping lever 10 as above
described; one cam 35 for operating the wing folders 17, 19, on the right hand
side and two cams 36 for pushing the right hand fingers 26.
:
The left hand shaft carries one cam 37 for operating the left hand wing
folders, and two cams 38 for pushing the left hand fingers 26.
The cycle of these cams' operations is as follows.
Cam 34 depresses and again releases the tripping lever 10, cam 35 operates
the right wing folder, cam 37 operates the left wing folder, cam 36 pushes the
right fingers, and cam 38 actuates the left fingers. The wing folder spindles 18
are rotated at the required point by means of reciprocating racks 39 and
pinions 40, the forward motion being imparted to the racks by yoked levers 41,
pivotted at 42 to the side frames and carrying striking plates 43, (Figs. 1,
19, and 20) with which the cams engage. Springs 44 serve to return the racks
and consequently the wing folders 17, 19, to normal position. The chain dotted
line 45 (Fig. 1) indicates the position of a light pulley or spur wheel to receive
power from any suitable source.
We are aware that machines having for their object to wrap caramels have
before this date been designed, but we consider that ours possesses advantages
over previous machines in that it is very simple of construction and has compara-
tively few moving parts.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. The combination of a slotted table adapted to support the caramel and its
paper, means for pushing the caramel downwards through said slot, a pair of
folders mounted on spindles adjacent to the track of the caramel, each folder
comprising a central flap loose on its spindle and two wings rigid on said
spindle, the latter adapted to make the end tucks in the paper, a spring connect-
ing said flap and wings together in such manner that they constantly tend to
maintain their relative positions, and means for completing the folding or
parcelling, substantially as described.
2. In a parcelling machine the combination of means for pushing the caramel
and its paper downwards through a slotted table and thus turning the paper
up at each side, spindles 18 carrying flaps 17 loose thereon and wings 19 rigid
therewith, a spring connecting said flap and wings, pinions mounted on said
spindles, racks adapted to turn said pinions, and means such as levers and cams
to actuate said racks, substantially as described and shown.
3. In a parcelling machine the combination with means for folding the paper

page_text: over the top of the caramel and effecting the first step in folding it over the
ends thereof, means consisting of four doors adapted to swing flat against the
ends of the caramel and thus complete the end tuck, substantially as described
and shown.
4. In a parcelling machine the combination with means for folding the paper
over the top of the caramel and effecting the first step in tucking it over the
ends, of four doors adapted to swing flat against the ends of the caramel in
pairs, fingers located adjacent to said doors and adapted to close them, and means
for operating said fingers substantially as described.
5. The combination of a plunger adapted to push the caramel and its paper
downwards, wing folders adapted to fold over the paper on the top of the
caramel and to commence the tucking over the ends thereof, doors adapted to
swing flat against the ends thereof and thus to complete the end tuck, shafts
mounted in the side plates of the machine and carrying cams for operating the
above devices, substantially as described.
6. The combination of side plates 1, transverse plate 21, supported thereby,
guides 22 carried by said plate, fingers 26 supported by said guides, doors 25
adapted to be closed by said fingers, spindles 28 upon which said doors are
mounted arms 29 carried by said spindles beneath said plate 21, and springs 30
attached to said arms, whereby the return of doors 25 to normal or inoperative
position is effected, substantially as described.
7. A parcelling machine in which the wrapping of the paper around the
caramel is completely effected in the following cycle; 1, turned up at each side
by a downward movement through a slot, 2, folded over the top and partially
over each end by the action of a pair of wing folders, one cam action only
being employed for each wing folder, 3, the end tuck completed at each end by
a pair of door folders, 4, the projecting tongue of paper turned up by a further
movement downwards, which movement is effected through the interposition of
another caramel which thus also receives its first fold at the time of its descent.
8. The improvements in parcelling machines taken as a whole substantially
as described and shown.
