Abstract
Abstract Apparatus is disclosed for feeding documents. The apparatus includes a feed bed having an upper and a lower part connected by a step. Documents are fed along the feed bed from the upper part to the lower part. Positioned above the step is a holdback member which engages the top edge of the leading document on the upper part of the feed bed. Thus the combined action of the step and the holdback member is to allow a trickle feed of documents from the upper to the lower part to maintain a substantially constant number of document on the lower part.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
150 words
Document feeding apparatus including a feed bed for supporting documents on edge and extending transversely of the feed bed, said feed bed including an upper part and a lower part and a step therebetween; means operable to feed documents along the feed bed from said upper part to said lower part; an abutment operative to isolate documents supported on the lower part from forces acting on documents supported on the upper part by engaging the leading face, adjacent its upper edge, of a leading document supported on the upper part of the feed bed and thereby being effective to restrain movement in the direction of feed of the upper edge of the leading document supported on the upper part and to permit movement of the upper edge of said document only when the lower edge of said document has descended the step from the upper part toward the lower part.
Claim 2
Dependent Claim
150 words
Document feeding apparatus including a feed bed for supporting documents on edge and extending transversely of the feed bed, said feed bed including an upper part and a lower part and a step therebetween; means operable to feed documents along the feed bed from said upper part to said lower part; an abutment operative to isolate documents supported on the lower part from forces acting on documents supported on the upper part by engaging the leading face, adjacent its upper edge, of a leading document supported on the upper part of the feed bed and thereby being effective to restrain movement in the direction of feed of the upper edge of the leading document supported on the upper part and to permit movement of the upper edge of said document only when the lower edge of said document has descended the step from the upper part toward the lower part.
Claim 3
Dependent Claim
37 words
Document feeding apparatus as claimed in claim 1 in which the step of the feed bed consists of a ramp extending from the upper part to the lower part and sloping downwards in the direction of feed.
Claim 4
Dependent Claim
42 words
Document feeding apparatus as claimed in claim 2 in which the abutment is operative to permit movement of the upper edge of the leading document only when the lower edge of the leading document has descended substantially the whole of the ramp.
Claim 5
Dependent Claim
24 words
Document feeding apparatus as claimed in claim 1 in which the abutment includes a pad of resilient material positioned to engage the leading document.
Claim 6
Dependent Claim
54 words
Document feeding apparatus as claimed in claim 1 including means to vibrate the feed bed; and a plurality of abutments on said feed bed operative to engage the lower edges of documents to be fed to prevent movement of the documents on the feed bed in a direction opposite to the direction of feeding.
Claim 7
Dependent Claim
19 words
Document feeding apparatus as claimed in claim 1 including means for removing documents in succession from the lower part.
