Filed: 1975-04-01
Abstract: 1481926 Stuffing boxes BALCKE-DURR AG 1 April 1975 [2 April 1974] 13229/75 Heading F2B In order to prevent sudden axial expansion of packing 3 in a piston pump, incompressible fluid in the space in which compression spring 6 is carried can, as the packing tends to expand on being relieved of fluid pressure, only escape slowly through the constricted gap 8 since, in this condition, the end gap 11 is closed by the spring. On the compression stroke, the end gap is opened by fluid pressure, so that the fluid enters the space freely via axial recesses 12, while the packing 3 is being axially compressed. The throttling effect of the gap 8 may be increased by the provision of labyrinth and like sealing formations (Figs. 3-6, not shown).

Knot-tying devices.-In a knot-tying device for making weavers knots, the strands a, b are laid across the device behind the knotting bill 11 from the same side and uncrossed. Fig. 1 shows the initial position of the strands a, b. When the thumb-piece 18 is depressed, the knotting bill 11 is turned by the engagement of its thread 10 with a toothed quadrant 15. The first half rotation of the bill makes a loop in the strand a. Further rotation makes a twist in the strand a and brings the loop, Fig. 5, across the strand b. A further half rotation carries the bill between the strands and loops the strand b into the strand a. Another half rotation brings the bill 11 upwards and opens its scissors to cut the strand b on the right-hand side of the bill, Fig. 7. At the same time, a pivoted arm 29 commences to swing outwards under the action of a pin and slot and causes the arm 33 to nip the thread a at 37, Fig. 7. As the bill further rotates, the arm 29 is swung outwards to its full extent and a lever 38 is operated to cause the scissors 32 to cut the thread a at the right-hand of the bill. The scissors of the bill 11 hold the thread b and as the arm 29 moves, it pulls the loop off the bill, Fig. 8, and makes the knot.
