Title: Improvements in or relating to straight bar knitting machines
Inventor: WICKARDT KURT WILLI
IPC: D04B11/00
Filed: 1950-03-27
Abstract: 706,092. Knitting-machines. THIEDE, W. O. March 22, 1951 [March 27, 1950], No. 7568/50. Class 74 (2) In a straight bar machine, an intermittently rotated element is gradually accelerated, in a given direction of rotation, into a given phase relationship with its driving means, by a clutch, of which either the rotatable driving member or the rotatable driven member has an abutment of gradually changing direction, including a portion substantially at right angles to the given direction, whilst the other member has a withdrawable element adapted to engage the abutment, means being provided for effecting such engagement by producing between element and abutment relative motion which includes a component in the given direction. The driven member 13, loose on driving shaft 11, is gradually accelerated as driving member 16 keyed to the shaft is moved axially thereof to engage the driven member. In the arrangement of Fig. 3, the engagement is by passage of a driving pin 19 along a groove 36 in the driven member which groove, at its mouth, is directed along the path of movement of the pin relative to the driven member but becomes progressively more axially directed towards its closed end. As the pin 19 is withdrawn, in declutching, it traverses an oppositely curved groove 37 and the driven member is thus progressively decelerated. In moving into its final driving position 19<1>, the pin 19 snaps past a spring urged tongue 39 which prevents its retraction along the groove 36. In a modification, Fig. 6, the grooves 36, 37 do not meet at their ends and, in engagement of the clutch, a pin 20 on the driven member is moved radially inwards of the shaft to engage the groove 36, a second pin 21 being held clear of the driven member. When engagement is complete, pin 20 is withdrawn and pin 21 projected inwardly to engage withdrawal groove 37 in preparation for declutching. The pins are projected and withdrawn by stationary cams 53, 54, 55, 56. In both forms, axial movement of driving member 16 is effected by face cams 22, 24 acting on a roller 23 moved from the path of one cam to that of the other by a radial cam 29 acting on a follower 28 on a plate 27 carrying the roller. A detent 34 prevents or permits movement of the plate 27. In a further modification, Fig. 10, the face cams 22, 24 are on the main camshaft 11 and, through a lever 60, operate a clutch, connecting and disconnecting a draw cam 59 to and from another shaft 11<1>. The pivot 61 of the lever is positioned to cause the lever to magnify the movements imparted to it by the cams 22, 24.
