Claim 11

Dependent Claim 34 words

Apparatus according to claim 8, in which said spindle means comprises a spindle rotatable on its own axis, said spindle carrying means comprising an angularly movable arm, and means to rotatably drive said spindle.

Claim 12

Dependent Claim 40 words

Apparatus according to claim 9, including also a plurality of said spindles and carrying means for each said spindle, said spindles being circularly spaced about a common axis, and including also means to index said spindles angularly about said axis.

Claim 13

Dependent Claim 70 words

Claim 14

Dependent Claim 50 words

Apparatus according to claim 11, including also second gear means on said shaft, and shaft second gear drive means, and in which said selective engagement means further selectively engages said shaft second gear and said second gear drive means to effect rotation of said spindles about their own respective axes.

Claim 15

Dependent Claim 72 words

Apparatus according to claim 12, in which said first and second shaft gear means define a pair of gears in axially spaced relation along said shaft, said selective engagement means comprising an axially spaced pair of drive gears, said shaft being axially bodily displaceable a predetermined distance between positions to alternately engage one member of each pair of gears, respectively to alternately angularly index and rotate said spindles on their own axes.

Claim 16

Dependent Claim 59 words

Apparatus according to claim 13 in which said pan has a central axis and including also a molten sugar distribution head rotatable about said central axis and adapted to form an annular mass of cotton candy circumscribed by the pan, and means differentially rotating the pan and head about said pan central axis in cotton candy mass forming relation.

Claim 17

Dependent Claim 98 words

Apparatus according to claim 14, in which said pan defines a first station, and including also second and third stations beyond said pan, said spindles being indexable between said stations in succession, whereby said spindles wind cotton candy around themselves at said first station for removal to said second station, said second station comprises means compacting the removed cotton candy in spindle carried relation for carriage to said third station, and said compacted cotton candy is separated from said spindles at said third station and the spindle returned to said first station while the cotton candy is recovered.
