Definitions

  • M TTORNEY provided at one end with a screw thread 25 and at the other with a hardened end 26 having a shoulder 21, is so mounted in the lever 2
  • the locking rod 24 can be displaced longitudinally, i. e. so adjusted that the end I6b of lever I6 can slide earlier or later off the end 26.
  • the thickness of the residue of yarn to be left on the bobbin is determinable by this adjustment.
  • Projecting laterally from the lever 2I is a pillar bolt 30 on which the roller 3
  • An eccentric disc 32 with, for example, two eccentric bosses 33, is keyed on to the driveshaft 6, said disc so acting on the roller 3
  • Fig. 6 shows an alternative form of the pin I1 and the feeler lever I3.
  • the face I'lb of the pin Ila is broad, and may be fiat, while the feeler lever I3b. which serves the same purpose as the feeler I3, has a semicircular boss I3c.
  • the purpose of the two shapes of contact surface of the pins II and Ila respectively is described later.
  • the feeler member 9 is rotatable on the pivot 8 and its arm 9b is pressed by the spring I against the uncovered portion 4a (Figs. 3 and 5) of the bobbin 4, said portion being indicated by the circle 31 in Fig. 4.
  • the feeler member I3 is pivotally mounted on the pivot I2 on the lever 9, being drawn by the spring 13a toward the bobbin. The f ree end of the feeler member I3 thus rests on the winding I4 of the bobbin, indicated by the circle 36 in Fig. 4, when the bobbin is in its unwinding position.
  • the lever 9b of the feeler member 9 rests on uncovered portion of the bobbin as before, while the feeler member I3 as before bears on the winding indicated by the circle 39. Because of the larger diameter 38 of the uncovered end of the bobbin however, the feeler member 9 takes a new position. i. e. it occupies the position shown by a dot-dash line in Fig. 4, and the feeler I3 is shifted with it. The tip I8 of the stop pin II always moves along the dash-dot line 42 in Fig. 4 however, as the winding I4 (36 or 39) is unwound,
  • the feeler lever 9b is pressed by the spring III against the uncovered portion 4a of the bobbin 4 as shown in Figs. 4 and 5, while at the same time the feeler member I3 is pressed against the Wound portion I4 of the bobbin 4. Since the feeler member I3 is pivoted, and pivoted in relation to the feeler lever 9b, the tip I8 of the pin I 'I on the lever I6 is free to move in the direction of the line 42 in Fig. 4. Initially, i. e. while a bobbin at A is completely filled, the lower end I 6b of the lever I6 stands well within range of the end 26 of lever 2 I, with the result that the lever 2I cannot tip upwards.
  • the pawl I6 is freed at intervals to turn on its pivot I5, and since the namely in the direction of the center of the pivot I. .Because of itsl tapered end, the action of the tip I8 of the pin I1 is not interfered with by the rotation of the feelers, and the same result is achieved by the boss I3c of Fig. 6.
  • the feeler I3 When a bobbin is ⁇ completely unwound, the feeler I3 will, of course, occupy some certain position with respect to the feeler 9; the particular position will depend on the construction of the parts; for example, the feeler may stand over the center of the post 8.
  • the feeler I3 will occupy substantially this particular position, with a completely unwound bobbin, regardless of whether the external diameter of the unwound bobbin is large or small. Accordingly a given residue of yarn on a bobbin will hold the feeler spaced a certain distance from this particular position, and the distance will be substantially the same Vregardless of whether the residue is on a bobbin of large diameter or on one of small diameter. As will be described hereunder. this distance serves the purpose of shutting off the unwinding process.l
  • two feelers In mechanism for bobbin unwinding, two feelers, one of said feelers being located to scan an uncovered portion of a bobbin being unwound and the other of said feelers being located to scan coils on the bobbin, and one of said feelers being in engagement with the other to affect the action of the latter, and a controller connected and responsive to said feelers to stop the unwinding operation.
  • said mechanism includes a magazine for bobbins and bobbin-advancing mechanism to advance'lled bobbins of said magazine to unwinding position seriatim, and said controller is connected to said bobbin-advancing mechanism to control the same.
  • two feelers In mechanism for bobbin unwinding, two feelers, one of said feelers being located to scan an uncovered portion of the bobbin being unwound and the other of said feelers being located to scan coils on the bobbin, and one of said feelers being mounted and movable on the other feeler to be positioned by the latter relative to the bobbin, and a controller responsive to said feelers to stop the unwinding operation.
  • mechanism forbobbinunwinding having'a member movable to stop the unwinding operations, a feeler pivoted at a nxed place to scan an uncovered portion of a bobbin being unwound, a feeler pivoted on the rst mentioned feeler to scan coils on the bobbin, said feelers being located to scan simultaneously the coils and uncovered portion of a bobbin, and a 6 controller connected to the second mentioned feeler and movable therewith from the path of said movable member.
  • vsaid movable member is a lever and said mechanism is an eccentric type mechanism to act on said lever.
