Abstract
Abstract An apparatus for receiving documents which tend to kite and/or curl upon being fed thereinto. The apparatus is made up of an elevatable platform which reduces curling problems upon low velocity feeding, and document elevatable wings which trap the leading edge of each document and overcome any curling and kiting problems during high velocity feeding.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
107 words
An apparatus for receiving documents fed thereinto at a low velocity during an initial stage of a feeding cycle and at a high velocity during a final stage of said feeding cycle by spaced low and high velocity feeding means located adjacent said apparatus, said apparatus comprising: a. platform means having a positionable receiving end for providing a base for receiving the leading edge of a document when fed thereonto at a low velocity during said initial stage; and b. throat means for trapping said leading edge, and being located adjacent an end opposite said receiving end, and extending toward said receiving end a sufficient extent to
Claim 2
Independent Claim
107 words
An apparatus for receiving documents fed thereinto at a low velocity during an initial stage of a feeding cycle and at a high velocity during a final stage of said feeding cycle by spaced low and high velocity feeding means located adjacent said apparatus, said apparatus comprising: a. platform means having a positionable receiving end for providing a base for receiving the leading edge of a document when fed thereonto at a low velocity during said initial stage; and b. throat means for trapping said leading edge, and being located adjacent an end opposite said receiving end, and extending toward said receiving end a sufficient extent to
Claim 3
Dependent Claim
88 words
trap said leading edge prior to said document being fed at said high velocity, and 2. not restrict access for removal of documents from said apparatus, said throat means including a number of wings, each comprising a side plate and an upswept top, and means supporting said wings for movement toward and away from said platform such that said wings are elevatable under the influence of said document when fed under said unswept top of said wings at said high velocity for removal of documents from said apparatus.
Claim 4
Dependent Claim
88 words
trap said leading edge prior to said document being fed at said high velocity, and 2. not restrict access for removal of documents from said apparatus, said throat means including a number of wings, each comprising a side plate and an upswept top, and means supporting said wings for movement toward and away from said platform such that said wings are elevatable under the influence of said document when fed under said unswept top of said wings at said high velocity for removal of documents from said apparatus.
Claim 5
Dependent Claim
30 words
An apparatus according to claim 1 wherein said supporting means includes carrying means connected to said platform means for carrying said wings and being adjustable for accommodating different length documents.
Claim 6
Dependent Claim
46 words
An apparatus according to claim 2 including guide means for each of said wings connected to said carrying means and through which said wings are carried by said carrying means, one of said guide means being slideable along said carrying means for accommodating different width documents.
Claim 7
Dependent Claim
45 words
An apparatus according to claim 3 including gudie tangs connected to said wings and guide slots in said guide means for cooperating with said guide tangs such that said wings can be elevated under the influence of said document when fed at said high velocity.
