Abstract
Abstract Document handling apparatus comprising an elongate and substantially rigid base mounted on four legs and an elongate carriage which is slidably mounted on the base. The carriage is formed with an elongate upwardly facing channel adapted to hold documents or alternatively to hold trays for documents and each end of the base is formed with two similar transversely spaced and longitudinally extending downwardly facing channels in which the upper end portions of the legs are located and mounted. The base is preferably formed with two upstanding longitudinally extending side walls and the carriage with two downwardly depending longitudinally extending side walls which overlap vertically with the upstanding side walls and rolling elements are mounted and contained between the upstanding and downwardly depending side walls enabling the carriage to be readily slidably moved on the base.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
68 words
Document sorting apparatus comprising an elongate and substantially rigid base having laterally-spaced longitudinal sides and an elongate carriage slidably mounted on the base and formed with an elongate upwardly facing channel adapted to hold documents or document holding trays, wherein each longitudinal side of the base is formed with a longitudinally extending downwardly and outwardly facing channel, and legs having rightangular upper end portions engaging in said channels.
Claim 2
Dependent Claim
68 words
Document sorting apparatus comprising an elongate and substantially rigid base having laterally-spaced longitudinal sides and an elongate carriage slidably mounted on the base and formed with an elongate upwardly facing channel adapted to hold documents or document holding trays, wherein each longitudinal side of the base is formed with a longitudinally extending downwardly and outwardly facing channel, and legs having rightangular upper end portions engaging in said channels.
Claim 3
Dependent Claim
20 words
Apparatus as claimed in claim 1, wherein the downwardly and outwardly facing channels extend the full length of the base.
Claim 4
Dependent Claim
40 words
Apparatus as claimed in claim 2, wherein the said two channels at each end of the base have parallel side walls which are inclined downwardly and outwardly from the vertical median plane of the base at an angle of 45*.
Claim 5
Dependent Claim
49 words
Apparatus as claimed in claim 3, wherein each leg comprises in addition to the upper end portion, an intermediate portion extending at right angles to the upper end portion and inclined to the vertical at approximately 45* and a lower vertical end portion extending 135* from the intermediate portion.
Claim 6
Dependent Claim
54 words
Apparatus as claimed in claim 4, wherein the upper end portion of each leg is externally square in section each channel in the base is correspondingly shaped and the upper end portion of each leg is mounted in a channel with a resilient pad clamped between the leg and the base of the channel.
Claim 7
Dependent Claim
74 words
Apparatus as claimed in claim 5, wherein the upper end portion of each leg is mounted in a channel with the aid of two spaced fastening members and the leg is pivotable about one of the fastening members when the other fastening member is removed so that the leg can be swung through 90* into a position in which the lower end portion of the leg lies parallel with and adjacent to the base.
Claim 8
Dependent Claim
84 words
Apparatus as claimed in claim 3, wherein the longitudinal sides of the base are each formed with an upstanding longitudinally extending side wall and the carriage is formed with two downwardly depending, longitudinally extending side walls which overlap vertically with the upstanding side walls of the base and wherein rolling elements are mounted and contained between the said upstanding side walls of the base and the downwardly depending side walls of the carriage enabling the carriage to be slidably moved relative to the base.
Claim 9
Dependent Claim
31 words
Apparatus as claimed in claim 7, wherein the rolling elements are mounted on the side walls of the carriage and roll in tracks formed in the side walls of the base.
Claim 10
Dependent Claim
31 words
Apparatus as claimed in claim 7, wherein the rolling elements are mounted on the side walls of the base and roll in tracks formed in the side walls of the carriage.
Claim 11
Dependent Claim
20 words
Apparatus as claimed in claim 9, wherein the base is formed as a single extrusion of a light-weight metal alloy.
Claim 12
Dependent Claim
