Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
314 words
Apparatus for the transfer in sequence, of sheets of material, from a conveyor to a mobile desk, comprising, a fixed horizontal frame having a longitudinal, horizontal central axis, first and second laterally spaced columns fixed with and upstanding from the forward end of said frame at opposite sides of said axis, first and second pulleys each journaled at the top of a respective one of said columns, for rotation on a common horizontal axis perpendicular to said longitudinal axis, conveyor means supporting and translating discrete sheets in succession to a terminal location beneath said frame and with one reference edge adjacent said columns and extending therebetween, a truck movable on said frame from a first horizontal position over a sheet in said terminal location, to a second and essentially vertical position between said columns, a plurality of suction cups carried by said truck in depending relation therefrom, means fixed with said frame, operable to elevate a sheet in said terminal location, into contact with said suction cups and to lift the same from said conveyor means, first and second parallel guide rails carried by said columns respectively, and extending from one terminal point each at the contiguous ends of edge of a sheet in said terminal location, upwardly and forwardly to a second terminal point atop said columns, follower means fixed with said truck at the forward end thereof, positively guided by said rails, first means connected with said truck and operable to move said follower means along said rails from said first to said second terminal points, to therEby elevate the forward end of said truck and a sheet affixed thereto, along and between said columns, said first means guiding the rearward end of said truck forwardly and downwardly, said truck and a sheet affixed thereto being essentially vertical between said columns when said follower means are positioned at said second terminal points.

Apparatus for the transfer in sequence, of sheets of material, from a conveyor to a mobile desk, comprising, a fixed horizontal frame having a longitudinal, horizontal central axis, first and second laterally spaced columns fixed with and upstanding from the forward end of said frame at opposite sides of said axis, first and second pulleys each journaled at the top of a respective one of said columns, for rotation on a common horizontal axis perpendicular to said longitudinal axis, conveyor means supporting and translating discrete sheets in succession to a terminal location beneath said frame and with one reference edge adjacent said columns and extending therebetween, a truck movable on said frame from a first horizontal position over a sheet in said terminal location, to a second and essentially vertical position between said columns, a plurality of suction cups carried by said truck in depending relation therefrom, means fixed with said frame, operable to elevate a sheet in said terminal location, into contact with said suction cups and to lift the same from said conveyor means, first and second parallel guide rails carried by said columns respectively, and extending from one terminal point each at the contiguous ends of edge of a sheet in said terminal location, upwardly and forwardly to a second terminal point atop said columns, follower means fixed with said truck at the forward end thereof, positively guided by said rails, first means connected with said truck and operable to move said follower means along said rails from said first to said second terminal points, to therEby elevate the forward end of said truck and a sheet affixed thereto, along and between said columns, said first means guiding the rearward end of said truck forwardly and downwardly, said truck and a sheet affixed thereto being essentially vertical between said columns when said follower means are positioned at said second terminal points.
Claim 3
Dependent Claim
19 words
The apparatus of claim 1, and means for optionally connecting all said suction cups to a source of vacuum.
Claim 4
Dependent Claim
69 words
The apparatus of claim 2, said first means comprising a chain, sprockets journaled on parallel axes extending between said columns at the base thereof, and at the rearward end of said frame, respectively, means connecting the rearward end of said truck to said chain, one said sprocket being power driven thereby to move said chain and truck, elevating the latter and a sheet affixed thereto, to essentially vertical position.
Claim 5
Dependent Claim
120 words
The apparatus of claim 3, said truck and a sheet affixed thereto being positioned at a delivery position upwardly and forwardly at a small acute angle, forwardly of said columns, when said follower means are at said second terminal points, track means adjacent said delivery position of said truck and inclined upwardly and rearwardly to the horizontal, at said small acute angle and in a vertical plane parallel with said longitudinal axis, a desk having a sheet-supporting base parallel with said track means, and means mounting said desk for guided translation on and along said track means, the lower edge of a sheet affixed to said truck when in delivery position, being essentially coplanar with, and over, said desk base.
Claim 6
Dependent Claim
41 words
The apparatus of claim 4, and means responsive to positioning of a sheet at said delivery position, to move said desk and base forwardly on and along said track means, by a distance essentially equal to the thickness of the sheet.
Claim 7
Dependent Claim
57 words
The apparatus of claim 1, a pulley at the top end of said columns and rotatable about a horizontal axis normal to said longitudinal axis, a cable having one end fixed to said truck and passing upwardly over and about said pulley, then downwardly, and a counterweight attached to the other and depending end of said cable.
