PROVISIONAL SPECIFICATION.
Improvements in Apparatus employed in the Manufacture of Stick
Candy.
I, BURCHARD THOENS, of No. 162 Annunciation Street New Orleans, Parish
of Orleans State of Louisiana, United States of America, Mechanical Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to apparatus employed for manufacturing striped and
twisted stick candy.
For this purpose I provide a steam jacketted vessel with a conical passage
terminating in an outlet nozzle, and a second vessel, which by preference is within
the former, also with a nozzle opening within the conical passage, which is enclosed
within a water jacket. Both vessels are provided with feed openings which can
be tightly closed; the steam jacket and the water jacket have suitable inlet and
outlet pipes with cocks or valves, and there is a pipe also furnished with a cock
or valve for admitting compressed air into the vessels, which communicate with
each other at the top.
Under the discharge nozzle there is a pair of rollers lying at an inclination
downwards from the nozzle and caused to revolve by worm or other suitable gear
both in the same direction.
These rollers are hollow and are cooled by circulation of water through them.
The vessels being charged with candy of different colours, tightly closed and heated
by steam in the jacket, air under pressure admitted to them forces two streams
of the candy out by the nozzles in a combined stream which moves down between
the rollers being turned over and over by their revolution and, as it becomes cool,
sets in the form of a twisted striped stick. The internal nozzle may be of various
forms and dimensions so as to emit the coloured candy as a ribbon more or less
thick to form the stripe.

Improvements in Apparatus employed in the Manufacture of Stick
Candy.
I, BURCHARD THOENS, of No. 162 Annunciation Street New Orleans Parish
of Orleans, State of Louisiana, United States of America, Mechanical 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 :-
My invention relates to apparatus employed for manufacturing striped and
twisted stick candy.
For this purpose 1 provide a steam jacketted vessel with a conical passage
terminating in an outlet nozzle, and a second vessel, which by preference is within
the former, also with a nozzle opening within the conical passage which is enclosed
within a water jacket. Both vessels are provided with feed openings which can
be tightly closed; the steam jacket and the water jacket have suitable inlet and
outlet pipes with cocks or valves, and there is a pipe also furnished with a cock
or valve for admitting compressed air into the vessels, which communicate with
each other at the top.
Under the discharge nozzle there is a pair of rollers lying at an inclination

page_text: downwards from the nozzle and caused to revolve by worm or other suitable gear
both in the same direction.
These rollers are hollow and are cooled by circulation of water through them.
The vessels being charged with candy of different colours, tightly closed and heated
by steam in the jacket, air under pressure admitted to them forces two streams
of the candy out by the nozzles in a combined stream which moves down between
the rollers being turned over and over by their revolution and, as it becomes
cool, sets in the form of a twisted striped stick. The internal nozzle may be of
various forms and dimensions so as to emit the coloured candy as a ribbon more or
less thick to form the stripe.
Fig. 1 of the accompanying drawing is a vertical section of the vessel, the
rollers below being shewn in elevation.
Fig. 2 is an end view of the rollers illustrating one means of driving them both
in the same direction.
Fig. 3 shews three different forms of mouth pieces for the interior vessel.
Fig. 4 shews end views of the mouth pieces shewn in Fig. 3.
a is the vessel provided with charging openings b, having removable covers c,
dis the steam jacket with steam inlet e steam outlet f and condensed water outlet 9.
An internal tube or vessel h with removable cover i projects down into the
conical pipe having an outlet j₁ and being surrounded by a hot water jacket k
provided with inlet and outlet pipes 1. To the lower end of the internal
tube h, is attached a mouth piece m of which three forms m m¹ m² are shown to
an enlarged scale in Figs. 3 and 4.
The apparatus described is supported over two hollow rollers n with tubular
shafts, through which cooling water is led by inlet and outlet pipes o o'. These
rollers are slowly revolved simultaneously and in the same direction by means of
worm gear was shown or by other suitable means. In order to give the candy
a downward motion, the rollers are inclined so that the candy glides down along
them while it revolves.
Prepared candy material, of desired consistence, being put into the vessel a and
material differing in colour or other quality being introduced into the internal
vessel and the covers and i being tightly closed, compressed air is introduced
into the vessel a through an opening p subjecting to pressure the candy material
in a and also in h which communicates with a by openings q.
This pressure forces the candy material out of the conical pipe j; and at the
same time out of the mouth piece m and both emerge together through the
outlet and pass into the gap between the two rollers n which, being revolved in
the same direction, twist or turn the candy stick, and as it glides along them,
the stick becomes cooled and hard by contact with the cool surfaces of the
rollers. The finished candy, striped and twisted, may then be removed to be cut
in lengths and packed.
By using hot water in the jacket k, the candy is made to issue readily, being
soft it would flatten, but being slowly revolved while cooling it keeps its cylindrical
shape.
The vessel might be outside the vessel a, and there might be several of the
vessels with mouth pieces m opening in the one conical pipe j. If the vessel h
were outside a, a tube leading to its mouth piece m would have to pass through
the wall of the vessel a or of the conical pipe ; and to be turned into proper
direction. Also the air pressure could be made to act in both vessels by simply
connecting their upper portions by a pipe.
For convenience in varying inclination, I mount the rollers n upon a support t
hinged to a base v and having a strut a adjustable in position.
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
claim is :-
1. In a candy machine, the combination with a main vessel, having at its lower

page_text: end a discharge nozzle, heating jackets surrounding the main vessel and its nozzle
and inclined hollow cooling rollers arranged beneath the discharge nozzle and
rotating in the same direction substantially as described.
2. In combination with the parts mentioned in the preceding claim a separate
vessel containing material differing in colour or other quality from that in the main
vessel, and having a mouth piece arranged within and discharging through the
discharge nozzle of the main vessel, substantially as described.
