Abstract
Abstract An apparatus for handling a plurality of articles, such as folded or collapsed boxes, which are received as a flow of articles moving in one direction from a conveyor device, characterized by a table arranged to receive the articles from an end of the conveyor device and having a pair of slots in a surface thereof, a pair of skates or skids received in the parallel slots and displaceable therealong for receiving the articles as they are deposited onto the table to transport the article across the table out of contact with the surface of the table. The device further includes a moveable stop which engages the skate combination and urges them in a direction toward the conveyor device and a brake device acting on the moveable stop to control the movement of the skate and flow of boxes across the table.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
200 words
An apparatus for handling a plurality of articles received as a flow of articles moving in one direction from a conveyor device having a surface for transporting the articles, said apparatus comprising a table with an upper surface disposed beneath the surface of the conveyor device and being arranged to receive the flow of articles from the end of the device, an elongated recess in said upper surface of the table extending parallel to said one direction, a plate mounted in said elongated recess for displacement therealong, said plate having an upper surface disposed at a level between the upper surface of the table and the surface of the conveyor device, said plate having means forming a stop for engaging the leading article of the flow of articles, means biasing the plate towards said conveyor device, and means applying a braking force to oppose movement of the plate in the opposite direction along said recess so that a force applied to the flow of articles by the conveyor device moves the articles onto the plate and displaces the plate away from the device and the force is free from resistance due to friction of the articles on the table surface.
Claim 2
Independent Claim
200 words
An apparatus for handling a plurality of articles received as a flow of articles moving in one direction from a conveyor device having a surface for transporting the articles, said apparatus comprising a table with an upper surface disposed beneath the surface of the conveyor device and being arranged to receive the flow of articles from the end of the device, an elongated recess in said upper surface of the table extending parallel to said one direction, a plate mounted in said elongated recess for displacement therealong, said plate having an upper surface disposed at a level between the upper surface of the table and the surface of the conveyor device, said plate having means forming a stop for engaging the leading article of the flow of articles, means biasing the plate towards said conveyor device, and means applying a braking force to oppose movement of the plate in the opposite direction along said recess so that a force applied to the flow of articles by the conveyor device moves the articles onto the plate and displaces the plate away from the device and the force is free from resistance due to friction of the articles on the table surface.
Claim 3
Dependent Claim
21 words
An apparatus according to claim 1, wherein the plate is mounted on a rollway having needle bearings disposed in said recess.
Claim 4
Dependent Claim
53 words
An apparatus according to claim 1, wherein the stop means is a separate element engaging a portion of the plate for moving the plate toward the conveyor device, said separate element of the stop means being linked to the brake means and to the means for biasing the plate toward the conveyor device.
Claim 5
Dependent Claim
91 words
An apparatus according to claim 1, wherein said recess is an elongated slot and said plate Is an elongated skate disposed in said slot, and which includes a second elongated slot parallel to the first mentioned slot, a second skate received in said second slot, means interconnecting the pair of skates, and wherein the stop means comprises a separate element engageable with the connecting means to displace the pair of skates, said separate element being connected to the brake means and to the means biasing the plate toward the conveyor device.
Claim 6
Dependent Claim
23 words
An apparatus according to claim 4, wherein each of the skates are mounted on a rollway having needle bearings disposed in the slot.
Claim 7
Dependent Claim
49 words
An apparatus according to claim 5, wherein the connecting means for the pair of skates is an angle iron, wherein the apparatus includes a fixed stop integral with said table engaging the angle iron to limit the travel of the skates in a direction away from the conveyor device.
Claim 8
Dependent Claim
51 words
An apparatus according to claim 4, which further includes a fixed stop integral with said table, and wherein said means forming the connection between the skates comprises an abutment surface for engaging said fixes top to limit displacement of the pair of skates in a direction away from the conveyor device.
