Abstract

An article handling apparatus including a generally vertical plate is disclosed for contacting and pushing articles along a generally horizontal surface. The plate is connected to a movable endless cable which is carried about the periphery of a pair of spaced wheels. A hollow dividing rail is supported upon the horizontal surface. In the preferred embodiment, a plurality of dividing rails are supported on the surface and divide the surface into a plurality of lanes. A pair of said wheels are rotatably mounted within each hollow rail adjacent opposite longitudinal ends thereof.

Claims

1. Article handling apparatus for pushing articles comprising a horizontally disposed shelf, spaced dividers on said shelf dividing the upper surface of said shelf into parallel lanes, said dividers having a rear end portion and a forward end portion, pusher means having a vertically disposed face for pushing articles along one of said lanes, said face extending generally perpendicular from the divider adjacent the lane in which the face is disposed, endless means supported by said divider for reciprocating said face along the lane in which it is disposed between a rear position adjacent said divider rear end position and a forward position, connecting means for connecting one end of said pusher means to a top run of said endless means so that said pusher means is pivotable about a vertical axis passing through said connecting means, a wheel supported by each end portion of said divider, at least the wheel at the rear end portion of said divider having a peripheral driving surface which is at least partially exposed so that it may be contacted by a drive means, said endless means extending around a portion of each wheel, said pusher means being pivotable only in its rear position from an article contacting position in its associated lane to a loading position wherein a major portion of said face projects beyond the longitudinal end of said divider and is generally parallel to a vertically disposed plane passing through the lengthwise dimension of said divider, and means to prevent said face from pivoting out of contact with an article when said face is in its associated lane and spaced from its rear position.

2. Apparatus in accordance with claim 1 wherein said divider is a hollow rail member having a V-shaped support for providing rigidity for the rail member and extending along a major portion of the longitudinal interior of said rail member and said connecting means being slideably guided by the top end of said rail member.

3. Apparatus in accordance with claim 1 wherein a portion of said pusher means overlies said connecting means and has a hole extending therethrough, faster means securing said overlying portion to said connecting means.

4. Apparatus in accordance with claim 1 wherein said last mentioned means includes an arm extending generally rearwardly from said face, said arm extending generally parallel to said divider and having a wheel thereon for rolling contact with a portion of said divider.

5. Apparatus in accordance with claim 1 wherein said peripheral driving surface of said wheel includes gear teeth, the teeth on said wheel being bifurcated by a V-shaped groove along the peripheral surface of said wheel, said endless means being a cable disposed within said groove.

6. Apparatus in accordance with claim 1 wherein said divider is hollow and has a cross section whereby the top and bottom portions have a greater transverse dimension than the central portion thereof, said wheels being journaled on axles supported by said central portion, and said endless means passing through said top and bottom portions.
