Title: Improvements in Machines for Cropping or Shearing Cloth.
Inventor: CANBY THOMAS
IPC: D06C13/00
Filed: 1917-04-02
Abstract: 114,465. Canby, T. April 2, 1917. Cropping and shearing.-In machines having detector-controlled means whereby, on the approach of the joined ends of the fabric, the cutter-stock is raised automatically, the cutters are held in the raised position until the joined ends of the fabric have passed the detector. The fabric 8, Fig. 1, passes between the tension rollers 9, 10 and over the peaks 11, 12 arranged beneath the helical cutter 4 and cutter blade 4a. A bracket 3 carrying the cutter-stock 3a and the cutters is pivoted at 2 to allow the cutters to be raised into the inoperative position. A detector-roller 14 is arranged beneath the tension roller 10, so that, when the joined ends of the fabric pass over it, it is depressed and actuates, through a rod 15, a bell-crank 16, a rod 21, and a lever 22, Fig. 3, to withdraw a latch 38 on a plunger 39 out of engagement with a projection 37 on a spring- controlled slip-ring 34 loosely mounted on a circular guide on a cam 29, which is loosely mounted on a driven shaft 26. When the projection 37 is freed, the slip-ring moves under the influence of the spring 34a till the projection 37 engages a stop 46 on the cam 29, the movement of the ring causing sockets 36 to move pawls 32, 33, pivoted to the cam, into engagement with oppositely-disposed teeth on a boss 28 fast on the shaft 26. The cam is thus rotated by the pawl 33 and operates, through a bowl 43 on a bell-crank lever 24, a rod 23, a bell-crank lever 18, a rod 19, and an arm 20 projecting from the cutter-stock 3a, which is thus raised. If the joined ends of the fabric have passed the detector-roller 14 before a second projection 40, Figs. 3 and 4, on the slip-ring reaches the latch 38, the latch will have moved into its normal position, and a finger 41 on the projection 40 will pass through a slot in the latch 38 and the cam 29 will complete a revolution, the pawl 32 preventing the cam from over-running the shaft 26 and thus preventing the cutter-stock from being lowered abruptly. If, however, the joined ends of the fabric have not passed the detector-roller 14, the finger 41 will be held by the latch 38 and the rotation of the cam 29 will be arrested at the position in which the cutters are raised. On the passing of the joined ends of the fabric, the cam completes its revolution and the pawls 32, 33 are withdrawn by the engagement of the projection 37 with the latch 38. A cam secured to the cam 29 has steps corresponding to the projections 37, 41, and is engaged to a spring-pressed bowl to prevent back-lash or vibration. A spring 48 is secured to the framework and to a projection 47 on the cutter-stock to check its downward motion. In the case of thin fabrics, an additional piece of fabric may be stitched to the joined ends of successive lengths of fabric to ensure the actuation of the detector.
