Abstract
Abstract A creel assembly for use in a business forms delivery apparatus wherein individual business forms are received between adjacent spirally formed fingers of a plurality of aligned creel assemblies for the purpose of inverting the business forms from a "face up" to a "face down" position. An individual creel assembly is provided in which a pair of finger support plates are secured together with equal numbers of fingers being mounted to each support plate and which fingers can be brought into registry with one another or positioned at intermediate locations between the fingers on another plate so that twice as many fingers are available for receiving business forms than when the fingers are positioned in registry with one another.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
163 words
A creel for use in a business forms delivery apparatus, comprising: a pair of plates; means for mounting said plates together for rotation about a common central axis of symmetry; a plurality of generally spirally formed fingers mounted at one end thereof to each of said plates so that both plates hold an equal number of said fingers at equally angularly spaced intervals and extending spirally outward from said axis counter to the direction of rotation of said plates; said mounting means including means for limiting rotation of said plates relative to one another about said axis between a position wherein said spirally formed fingers on one of said plates are in registry with those on the other of said plates and a position in which said spirally formed fingers on said one plate are disposed equidistant between said spirally formed fingers on said other plate, said mounting means further including means for releasably holding said plates in either one of said positions.
Claim 2
Dependent Claim

A creel for use in a business forms delivery apparatus, comprising: a pair of plates; means for mounting said plates together for rotation about a common central axis of symmetry; a plurality of generally spirally formed fingers mounted at one end thereof to each of said plates so that both plates hold an equal number of said fingers at equally angularly spaced intervals and extending spirally outward from said axis counter to the direction of rotation of said plates; said mounting means including means for limiting rotation of said plates relative to one another about said axis between a position wherein said spirally formed fingers on one of said plates are in registry with those on the other of said plates and a position in which said spirally formed fingers on said one plate are disposed equidistant between said spirally formed fingers on said other plate, said mounting means further including means for releasably holding said plates in either one of said positions.
Claim 3
Dependent Claim
19 words
A creel as defined in claim 1 wherein said spirally formed fingers are wires releasably secured to said plates.
Claim 4
Dependent Claim
19 words
A creel as defined in claim 1 wherein there are three spirally formed fingers secured to each said plate.
Claim 5
Dependent Claim
65 words
A creel as defined in claim 1 wherein said limiting means includes a pair of arcuate slots defined in one of said plates concentrically disposed with said axis and a pair of bolts threadably engaged in corresponding holes in the other of said plates and each extending through a corresponding slot, the length of said slots limiting relative rotation of said plates between said positions.
