Abstract

107,909. British Northrop Loom Co., (Northrop Loom Co.). Nov. 8, 1916. Weft, cutting.-In a weft-replenishing loom, a conduit is mounted between the cloth selvedge and the adjacent shuttle box so that the weft to be cut extends across its entrance, and means are provided for producing currents of air into the entrance to carry the weft end into the conduit after it has been cut, first from the bobbin in the shuttle and finally from the selvedge; the conduit may be positioned to remove the weft end of the fresh supply after it has been cut at the selvedge. As shown, the loom is provided with a selvedge-weft cutter 24, Fig. 1, carried by the temple 23, and a weft-cutter adjacent to the shuttle box 2 and comprising the usual fixed and movable blades 5, 6 carried by the arm 8. The heel of the movable blade is provided with an abutment, preferably formed as a roller 18, to contact with an adjustable stop 19 on the breast beam 3 as the cutter returns to its forward position after cutting and clamping the weft end, so that the jaws are opened and the severed end is released. A conduit 27 is mounted in a tubular hearing 26, secured by a bracket 25 to the breast beam, and is normally pressed towards the lay by a spring 29, Fig. 4, so that it may yield if the shuttle is trapped opposite its end. Air is drawn by suction into the conduit 27, so that, when the weft end a is cut by and released from the blades 5, 6, it is drawn into the conduit as shown by the dotted line, and, when the cutter 24 has severed the weft end at the selvedge, the end is drawn through the conduit into a receiver 57 provided with a lid 58 and a wire-gauze or like screen 59, which can be raised by attached arms 61 for cleaning purposes. The receiver is connected by a tubular projection 60 and a flexible tube 54 to a double-acting suction pump mounted on the loom and driven from the crank or cam shaft through belt gearing, a crank-pin, and a connecting-rod, or to a pump provided in connexion with a series of looms.
