Title: Knitting Machine.
IPC: D04B1/06
Filed: 1968-02-20
Abstract: 1,151,140. Knitting. SCOTT & WILLIAMS, Inc. 20 Feb., 1968 [2 Nov., 1967; 8 Feb., 1968], No. 8219/68. Headings D1C and D1K. A stocking having a toe knitted and closed by twisting as disclosed in Specification 1,037,200, has the welt finished as described in that Specification followed by a tab produced by knitting a number of courses prior to the fabric being castoff the needles which tab has a run resistant structure and is of a nature which has a tendency for the fabric of the tab portion to roll up on itself. To augment the anti-raveling characteristics of the fabric of the tab portion the present invention provides a heater element 134 which is projected prior to the fabric being cast-off the needles and at a time when the needles are lowered and the sinkers withdrawn. The fabric of the tab portion hanging on the needles assumes a puckered appearance and on contacting the heater element 134 the yarns of the courses which are of a thermoplastic synthetic nature are caused to fuse together whilst maintaining the basic structure of the fabric. The resultant brittleness of the yarns when they are fused enables the subsequent portion of fabric to be broken off whilst producing a non raveling edge which can roll up with the remainder of the tab and be enclosed within the curled portion thereof. The heater element is projected at the desired times on completion of a stocking and in coordination with the needle and sinker cams lowering the needles and withdrawing the sinkers. A pneumatic take down mechanism is provided for withdrawing the fabric and nozzles adjacent the feeders serve to cause the fabric to assume an undulating attitude for contact by the heater element. In addition coarse and fine yarns may be fed at separate feeding stations to provide fine yarns which will fuse more readily to the coarser yarns.

Title: Improvements relating to seed drills
IPC: A01B69/02
Filed: 1930-03-17
Abstract: 350,948. Distributers for seeds. KNAPP, T. E., Thames Valley Ironworks, Clanfield, Oxfordshire. March 17, 1930, No. 8575. [Class 6 (i).] A tractor-drawn seed-drill is provided with two rows of coulters having independent sets of feed runs visible to the tractor driver, and with means for putting the coulters into and out of action driven from the travelling wheels and controlled from the tractor driver's seat. The two sets of coulter bars 3, 4 are of equal length and there is a separate seed box 7, 8 for each of the two rows of coulters 1, 2, the front box 7 being at a higher level than the box 8. The feed runs delivering into flexible tubes 11, 12 leading to the coulters are open towards the front. The frame 13 is supported by a live axle 14 and wheels 15, an auxiliary axle 16 being provided at right-angles to the axle 14 to receive the wheels temporarily for passing through gateways, &c. The feed spindles 23, 24 carry corrugated feed rollers 27 and are driven by spur gearing from the axle 14 through a gear wheel 18 carried by a spring- controlled swinging plate so as to be put in and out of gear when the coulters are lowered and raised. When a cable 52 is pulled from the driver's seat it moves a pivoted lever 46 and thus raises a spring-controlled roller 38 from between jaws 37 on a plate 34 and allows a spring-controlled latch 42 on the plate to carry a stop pin 45 into engagement with an internally serrated flanged disc 32 driven from the axle 14 by a chain 29. This causes the plate 34 to move round with the disc 32 until an adjustably mounted roller 51 on the lever 46 passes between the jaws 37 and stops it. This depresses the coulters 1, 2 since a crank pin 60 on an arm 61 keyed to the spindle of the plate 34 engages in a slot in a pivoted beam 56 carrying a bar 53 to which the coulters are connected by springs 54, 55. The coulters are raised when the cable 52 is pulled again and the plate 34 completes a revolution. The upper part of the slotted beam 56 may be adjustable from the driver's seat to alter the width of the slot and therefore the depth of work of the coulters. The feed spindles 23, 24 are movable longitudinally by levers 65a to regulate the feed and to cause cylindrical bearing parts 63 to move across the mouth of the feed runs. Trailing track markers 67 are connected by chains to laterally projecting supports 66.
