Abstract

1392730 Dobbies ELITEX-ZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI 29 Dec 1972 [4 Jan 1972] 60197/72 Heading DIE In a dobby the draw lines 103, 104 and lifting hooks 5, 6 are movable in arcuate paths each being pivoted about the same point i.e. the pivots 1, 2. As shown two armed levers 3, 4 are connected to a baulk lever 14 and have pivotable hooks 5, 6 at their ends each of which is normally urged by a spring against a stop 112, 113. A driving member 300, 301 continuously oscillatable by a cam driven axiatly slidable rod 209, 210 to move the hook 5, 6 into engagement with its approprite draw knife. The rods 209, 210 are normally urged by springs 211, 212 to an inoperative position but when a solenoid 201 is actuated from a pattern card or the like the rod 203 thereon holds the rod 205 in the position shown in Fig 1 so that the driving member 300 can act on its respective rod 209. The draw knives are driven from a cam 108 as shown in Fig 5 and the driving members from a cam 315 as shown in Fig 4. The cam 315 has a lost motion slot 309 to facilitate reverse motion of the dobby. In modifications, the solenoid 201 can be replaced by a drum with projections which act directly on levers equivalent to levers 205.
