Abstract
Abstract A circular platform carrying a pack of sheets standing on edge extending generally radially of the platform and leaning against a sloping backing is rotated about an upright axis so that the plane of the pack face moves successively into registry with inlet slots of narrow tilted bins arranged substantially radially edgewise around the rotating platform. A surface sheet pusher and a feed roller move successive sheets from the face of the sheet pack into circumferentially succeeding bins as the platform rotates so that at the end of a complete revolution of the platform, one sheet can have been fed from the pack into each of the bins.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
39 words
A collator comprising a series of stationary sheet-receiving bins arranged in a circular arc, and sheet feed means located inside such circular arc of stationary sheet-receiving bins and operable to project sheets edgewise sequentially into bins of said series.
Claim 2
Dependent Claim
39 words
A collator comprising a series of stationary sheet-receiving bins arranged in a circular arc, and sheet feed means located inside such circular arc of stationary sheet-receiving bins and operable to project sheets edgewise sequentially into bins of said series.
Claim 3
Dependent Claim
30 words
The collator defined in claim 1, and means supporting the sheet feed means for rotation about the axis of the circular arc in which the stationary sheet-receiving bins are arranged.
Claim 4
Dependent Claim
63 words
The collator defined in claim 1, in which the sheet feed means includes rotatable sheet-pack-supporting means located inside the circular arc of the stationary sheet-receiving bins for supporting a pack of sheets from which sheets are projected edgewise into bins in the circular arc, and means mounting said sheet-pack-supporting means for rotation about the axis of the circular arc of stationary sheet-receiving bins.
Claim 5
Dependent Claim
34 words
The collator defined in claim 3, in which the axis of the circular arc of stationary sheet-receiving bins is upright, and the rotatable sheet-pack-supporting means includes a circular platform rotatable about such upright axis.
Claim 6
Dependent Claim
38 words
The collator defined in claim 4, in which the rotatable sheet-pack-supporting means further includes means on the platform for supporting a pack of sheets on edge, and the bins are narrow in directions generally tangentially of the platform.
Claim 7
Dependent Claim
40 words
The collator defined in claim 5, in which the sheet-pack-supporting means includes a sloping backing on the platform and disposed generally radially of the platform for supporting a sheet pack in tilted position, and the bins are tilted generally correspondingly.
Claim 8
Dependent Claim
26 words
The collator defined in claim 5, in which the bottoms of the bins are disposed at an elevation substantially lower than the elevation of the platform.
Claim 9
Dependent Claim
58 words
The collator defined in claim 5, in which the sheet-supporting means includes an upright backing wall against which a pack of sheets can bear, the sheet feed means includes a sheet-engaging member engageable with the outer sheet of such pack, and retracting means operable by rotation of the platform to retract the sheet-engaging member away from said wall.
Claim 10
Dependent Claim
23 words
The collator defined in claim 8, in which the retracting means includes a solenoid and a movable Core connected to the sheet-engaging member.
Claim 11
Dependent Claim
37 words
The collator defined in claim 8, in which the retracting means includes an arm engageable with the sheet-engaging member and cam means operable by rotation of the platform to swing said arm for retracting the sheet-engaging member.
Claim 12
Dependent Claim
104 words
A collator comprising a series of stationary sheet-receiving bins arranged in fixed relationship to each other in a circular arc with the axis of such arc upright and having slots opening generally radially of such arc with their lengths upright, sheet feed means located alongside said sheet-receiving bins and operable to project successive sheets in upright planes edgewise through said upright generally radially opening slots into said bins, and means effecting rotation of said sheet feed means about the upright axis of said bin circular arc to place said sheet feed means successively in registry with the slots of different bins of said series.
Claim 13
Dependent Claim
104 words
A collator comprising a series of stationary sheet-receiving bins arranged in fixed relationship to each other in a circular arc with the axis of such arc upright and having slots opening generally radially of such arc with their lengths upright, sheet feed means located alongside said sheet-receiving bins and operable to project successive sheets in upright planes edgewise through said upright generally radially opening slots into said bins, and means effecting rotation of said sheet feed means about the upright axis of said bin circular arc to place said sheet feed means successively in registry with the slots of different bins of said series.
Claim 14
Dependent Claim
31 words
The collator defined in claim 11, and guide means between the sheet feed means and the bins to guide edgewise movement of sheets from the sheet feed means to the bins.
Claim 15
Dependent Claim
28 words
The collator defined in claim 12, in which the guide means defines a slit through which sheets can be fed from the sheet feed means to the bins.
Claim 16
Dependent Claim
26 words
The collator defined in claim 13, and feed roller means adjacent to the guide means for effecting movement of a sheet through the guide means slit.
Claim 17
Dependent Claim
33 words
The collator defined in claim 14, in which the feed roller means includes a live feed roller and a cooperating idler pressure wheel engageable with said feed roller for movement of sheets therebetween.
Claim 18
Dependent Claim
98 words
A collator comprising a series of sheet-receiving bins arranged in fixed relationship to each other in a circular arc and having slots opening inwardly generally radially of such arc, sheet feed means located inside the circular arc of said sheet-receiving bins and operable to project successive sheets edgewise outwardly through such inwardly opening slots into said bins, and means effecting relative rotation of said series of bins and said sheet feed means about the axis of said bin circular arc to place said sheet feed means successively in registry with the slots of different bins of said series.
Claim 19
Dependent Claim
98 words
A collator comprising a series of sheet-receiving bins arranged in fixed relationship to each other in a circular arc and having slots opening inwardly generally radially of such arc, sheet feed means located inside the circular arc of said sheet-receiving bins and operable to project successive sheets edgewise outwardly through such inwardly opening slots into said bins, and means effecting relative rotation of said series of bins and said sheet feed means about the axis of said bin circular arc to place said sheet feed means successively in registry with the slots of different bins of said series.
Claim 20
Dependent Claim
106 words
A collator comprising a series of sheet-receiving bins arranged in a circular arc, rotatable sheet pack supporting means located inside said circular arc of sheet-receiving bins and including a platform rotatable about an upright axis for supporting a pack of sheets on edge and a sloping backing on said platform disposed generally radially of said platform for supporting the sheet pack in tilted position, said bins being tilted generally correspondingly, and sheet feed means including a live feed roller and a cooperating idler pressure roller engageable with said feed roller for projecting successive sheets from said sheet pack edgewise into successive bins of said series, respectively.
