Abstract

Abstract A device for discharging processed or worked lengths of material from a work table the lengths having a part lying on the work table and a part hanging over an edge thereof. The device includes a pair of parallel superposed perforate conduits spaced from the edge of the table and connected to a source of compressed air, and a receiving bar pivoted about an axis below the table on which the lengths are eventually straddled. The upper conduit is positioned at the level of the work table and the lower bar is positioned at the same level as the receiving bar. The jet of air formed by the lower conduit retains the portion hanging over the end of the table against the receiving bar while the jet of air formed by the upper conduit flips the part of the length lying on the table onto the receiving bar such that the length is straddled on the receiving bar.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 190 words
A device for discharging lengths of material from a work table, the lengths having a part lying on the work table and a part hanging over an edge thereof, comprising a pair of parallel superposed perforate conduits spaced from the edge of the work table, the conduits being adapted to be connected to a source of air under pressure to produce jets of air, a receiving bar disposed at a level beneath the work table, the upper conduit being positioned at the level of the work table and the lower conduit being positioned at the level of the receiving bar, and a detachable overhanging portion connecting the upper surface of the work table with the upper conduit, whereby a jet of air from the lower conduit retains the part of the length hanging over the table against the receiving bar while the jet of air from the upper conduit flips the part of the length lying on the work table over the receiving bar, so that the side of the length facing up on the table before discharge is the side facing down straddled on the receiving bar after discharge.
Claim 2
Independent Claim 190 words
A device for discharging lengths of material from a work table, the lengths having a part lying on the work table and a part hanging over an edge thereof, comprising a pair of parallel superposed perforate conduits spaced from the edge of the work table, the conduits being adapted to be connected to a source of air under pressure to produce jets of air, a receiving bar disposed at a level beneath the work table, the upper conduit being positioned at the level of the work table and the lower conduit being positioned at the level of the receiving bar, and a detachable overhanging portion connecting the upper surface of the work table with the upper conduit, whereby a jet of air from the lower conduit retains the part of the length hanging over the table against the receiving bar while the jet of air from the upper conduit flips the part of the length lying on the work table over the receiving bar, so that the side of the length facing up on the table before discharge is the side facing down straddled on the receiving bar after discharge.
Claim 3
Independent Claim 184 words
A device for discharging lengths of material from a work table, the lengths having a part lying on the work table and a part hanging over an edge thereof, comprising a pair of parallel superposed perforate conduits spaced from the edge of the work table, the conduits being adapted to be connected to a source of air under pressure to produce jets of air, and a receiving bar disposed at a level beneath the work table, the upper conduit being positioned at the level of the work table and the lower conduit being positioned at the level of the receiving bar, said receiving bar being disposed between said conduits And said table, whereby a jet of air from the lower conduit retains the part of the length hanging over the table against the receiving bar while the jet of air from he upper conduit flips the part of the length lying on the work table over the receiving bar, so that the side of the length facing up on the table before discharge is facing up when straddled on the receiving bar after discharge.
Claim 4
Independent Claim 184 words
A device for discharging lengths of material from a work table, the lengths having a part lying on the work table and a part hanging over an edge thereof, comprising a pair of parallel superposed perforate conduits spaced from the edge of the work table, the conduits being adapted to be connected to a source of air under pressure to produce jets of air, and a receiving bar disposed at a level beneath the work table, the upper conduit being positioned at the level of the work table and the lower conduit being positioned at the level of the receiving bar, said receiving bar being disposed between said conduits And said table, whereby a jet of air from the lower conduit retains the part of the length hanging over the table against the receiving bar while the jet of air from he upper conduit flips the part of the length lying on the work table over the receiving bar, so that the side of the length facing up on the table before discharge is facing up when straddled on the receiving bar after discharge.
