Abstract
Abstract Apparatus for making ''''candyfloss'''' comprising a rotatable trough into which sugar filaments are spun from a drum rotating at an angular speed higher than that of the trough whereby candyfloss can be wound on a stationary stick held in the trough. A pre-payment control device controls dispensing of the sticks to be held in the trough, and also activates the drive motor. Adjustment means in the sugar supply system enable adjustment of the volume of sugar dispensed at each vend.

Claim 1
Independent Claim
300 words
In apparatus for producing the sugary confectionery called ''''candyfloss'''' and consisting of filaments of sugar attached to and wound around a small stick such apparatus comprising a framed housing; a circular trough mounted interiorly of this framed housing with its axis vertical; a rotary hollow drum located coaxially in said trough with its axis vertical; means mounting said drum for rotation about said vertical axis; heating means operative to maintain the interior of said drum at an elevated temperature; a feed opening in the upper wall of said drum; outlet orifice means for the sugar filaments and formed in the lateral peripheral wall of said drum; sugar container means disposed in said housing; a dispensing tube communicating said sugar container means with said feed opening of the rotary drum; a sugar dispenser interposed between said sugar container means and the dispensing tube; a control unit operatively associated with said sugar dispenser; a drive motor disposed coaxially of the rotary drum and beneath the trough; an output shaft of said drive motor passing through said trough and attached to the rotary drum; further control units effective to control said drive motor and heating means said further control units including timer means; and pre-payment control means connected to the control unit of the sugar dispenser and to said further control units; the improvement comprising means for adjusting the volume of sugar dispensed by said sugar dispenser; means mounting said trough for rotation about its axis; drive means capable of imparting to said trough an angular speed lower than that of said rotary drum; a reservoir for containing sticks onto which in use of the apparatus candyfloss will be wound; means for dispensing sticks individually from said reservoir; and a control unit for said dispensing means operatively associated with said prepayment control means.

In apparatus for producing the sugary confectionery called ''''candyfloss'''' and consisting of filaments of sugar attached to and wound around a small stick such apparatus comprising a framed housing; a circular trough mounted interiorly of this framed housing with its axis vertical; a rotary hollow drum located coaxially in said trough with its axis vertical; means mounting said drum for rotation about said vertical axis; heating means operative to maintain the interior of said drum at an elevated temperature; a feed opening in the upper wall of said drum; outlet orifice means for the sugar filaments and formed in the lateral peripheral wall of said drum; sugar container means disposed in said housing; a dispensing tube communicating said sugar container means with said feed opening of the rotary drum; a sugar dispenser interposed between said sugar container means and the dispensing tube; a control unit operatively associated with said sugar dispenser; a drive motor disposed coaxially of the rotary drum and beneath the trough; an output shaft of said drive motor passing through said trough and attached to the rotary drum; further control units effective to control said drive motor and heating means said further control units including timer means; and pre-payment control means connected to the control unit of the sugar dispenser and to said further control units; the improvement comprising means for adjusting the volume of sugar dispensed by said sugar dispenser; means mounting said trough for rotation about its axis; drive means capable of imparting to said trough an angular speed lower than that of said rotary drum; a reservoir for containing sticks onto which in use of the apparatus candyfloss will be wound; means for dispensing sticks individually from said reservoir; and a control unit for said dispensing means operatively associated with said prepayment control means.
Claim 3
Dependent Claim
35 words
Apparatus as set forth in claim 1 wherein said drive means for the trough are actuated to cause the said trough to rotate in the same sense of rotation as that of the rotary drum.
Claim 4
Dependent Claim
37 words
Apparatus as set forth in claim 1 wherein said drive means for the trough are actuated such as to cause the said trough to rotate in the sense of rotation opposed to that of the rotary drum.
Claim 5
Dependent Claim
38 words
Apparatus as set forth in claim 1 wherein the drive means of the trough comprise a reduction gearbox interposed between the output shaft of said drive motor for the drum and said means mounting the trough for rotation.
Claim 6
Dependent Claim
52 words
Apparatus as set forth in claIm 1 wherein said means mounting the trough for rotation includes a pulley coaxial with said trough and secured thereto; and wherein said drive means for the trough includes a drive pulley driven for rotation, and a drive belt passing around said pulley and said drive pulley.
Claim 7
Dependent Claim
123 words
Apparatus as set forth in claim 1 wherein said sugar dispenser comprises a body; means defining a cylindrical bore in said body; inlet and outlet connector means communicating with said bore at locations offset by a given distance along the axis of the bore, said inlet connector means being connected to said sugar container means and said outlet connector means being connected to said dispensing tube; two axially spaced coaxial pistons slidably mounted in the bore; a control solenoid; an armature of said solenoid; means connecting said armature to a first of two pistons; and means mounting said armature for axial movement; and wherein said means for adjusting the volume of sugar dispensed comprise adjustable spacer means connecting said first and second pistons.
Claim 8
Dependent Claim
28 words
Apparatus as set forth in claim 6, wherein said container means comprise a plurality of individual containers each having its own dispenser and connected to said dispensing tube.
Claim 9
Dependent Claim
88 words
Apparatus as set forth in claim 1, wherein said stick dispenser comprises a stick pusher, means mounting said pusher for axial movement through a wall of said reservoir, a stick delivery opening fashioned at the base of a wall of the reservoir opposite to said one wall, a return spring acting on said pusher urging it away from said delivery opening, lever means disposed to act on said pusher in a sense opposing said spring; and a solenoid having an armature operatively connected to the said lever means.
