Definitions

  • ABSTRACT OF THE DISCLOSURE Suspension type bobbin holder by which a bobbin for thread, sliver or roving is releasably suspended for free rotation from the creel board or creel rail of a spinning machine or the like, and comprising an elongate shell for insertion into the opening in a bobbin, pawls extendable outwardly from the shell to engage the interior portion of the bobbin, and a sleeve slidable along the shell to actuate the pawls.
  • the required motion is simply a fixed upward motion of the bobbin relative to the bobbin holder yet this motion must be positively performed before the bobbin will be released from the bobbin holder.
  • This motion is easily mastered by the operator of a machine and does not require the operator to remember and master a motion of a bobbin relative to the bobbin holder when the bobbin is to be positioned and an entirely different motion of a bobbin relative to the bobbin holder when the bobbin is to be released.
  • the bobbin holder disclosed herein effectively locks the pawls in outward bobbin-holding position in bobbins of a variety of sizes. Regardless of bobbin size, the pawls will not damage the bobbin or become jammed in the bobbin as they become effectively locked in bobbinholding position.
  • the bobbin holder disclosed herein is durable in construction and relatively easy and inexpensive to manufacture.
  • the bobbin holder disclosed herein provides the advantages of a universal bobbin holder while completely eliminating the difficulties encountered. with previous universal bobbin holders.
  • a bobbin holder having the customary bullet shaped outer shell which extends into the recess of a bobbin and which is rotatably suspended downward from the creel board or creel rail of a spinning or similar machine, having a wedge member slidably movably within the outer shell, having pawls with their upper ends pivotally mounted within the outer shell and their lower ends positioned to extend or retract through slots in outer shell in accordance with the position of the wedge member, having a sleeve slidably movable along the outer surface of the outer shell as it is engaged and moved by the upper edge of a bobbin being positioned or released from the bobbin holder, and having operating means for alternately checking downward motion of the Wedge member and permitting the downward motion of the wedge member in response to repeated identical upward motions of the sleeve.
  • FIG. 4 is a fragmentary elevational view of the inside of the right shell of the embodiment of the invention shown in FIG. 1 and shows the motion of the right cam rod in response to upward motion of the wedge member as a bobbin is being removed from the bobbin holder by initial upward movement;
  • the suspension assembly T is suspended from the creel rail E by a bolt 80 which extends upwardly from the suspension assembly T through a hole 15 in the creel rail E and which is threadably engaged at its upper end by a locking plate 16 positioned within the creel rail E.
  • the suspension assembly T is arranged to permit the outer shell S to be freely rotatable.
  • the outer shell S has a right slot 18 extending through it for a portion of its length and left slot 19 extending through it for a portion of its length on the opposite side from the right slot 18.
  • a shaft 20 extends through the right slot 18, through a wedge member C slidably positioned within the outer shell S, and through the left slot 19.
  • the extending ends of the shaft 20 protrude within recesses 21 extending along the length of the shell S.
  • the recesses 21 are centered on the slots 18 and 15 and nubs 22 on the sleeve R extend into the recesses 21 to engage the shaft 20 when the sleeve R is moved along the length of the shell S.
  • a right pawl 56 and a left pawl 51 are pivotally carried by the right half 36 and the left half 38 respectively on opposite sides of the wedge member C.
  • the upper end of each of the pawls 5t) and 51 extends into recesses 56 in the right half 36 and the left half 33.
  • a land 58 is provided on each of the pawls 50 and 51 to act as a bearing surface to be engaged by the wedge member C in a manner to be described.
  • the wedge member C is an elongated member with a wedge-shaped end 59 which extends between the pawls 5t) and 51.
  • the wedge member C is urged downwardly by a spring 14 positioned in the cavity V between the upper end of the wedge member C and a disc 43 closing the upper end of the outer shell S.
  • the wedge-shaped end 59 engages the lands 58 of the pawls 50 and 51 and forces the pawls 50 and 51 to pivot outwardly through openings 52 and 54 in opposite sides of the outer shell S at its lower end.
  • the downward motion of the wedge member C in response to the spring 14 is controlled by an operating means responsive to the upward motion of the sleeve R and which alternately holds the wedge member C in an upward position at which the wedge member C is not between the pawls S0 and 51 and releases the wedge member C for that downward motion which pivots the pawls 50 and 51 outwardly.
  • the operating means comprises cam rods 66 and 68 carried by the Wedge member C and camming channels 69 and 70 formed in the inner surface of the outer shell S.
  • the arrangement of this operation means will be understood from the following description.
  • the collar 64 carries the right cam rod 66 and the left cam rod 68 extending in diametrically opposite directions from the circumference of the collar 64 with their center lines coinciding with each other and perpendicular to the centerline of the wedge member C.
  • the right cam rod 66 extends into the right camming channel 69 formed in the inner surface of the right half 36 of the outer shell S and the left cam rod 68 extends into the left camming channel 70 formed in the inner surface of the left half 38 of the outer shell S.
  • the camming channels 69 and 70 are substantially identical to each other so that they cause the cam rods 66 and 68 to move together as a single unit as the wedge member C moves upward and downward within the cavity V. Thus, only the motion of the right cam rod 66 in the right camming channel 69 will be described. However, the detailed construction of both camming channels 69 and 70 will be understood from this description provided it is also understood that the sleeve R moves upwardly and downwardly with a bobbin B and that upward motion of the sleeve R will move the shaft 20, the cam rods 66 and 68, and wedge member C upwardly.
  • the camming channel 69 forms an island member 71 which together with the outer edges of the camming channel 69 defines a path P1 in which the right cam rod 66 moves as a bobbin B moves upward along the outer shell S to be released from the bobbin holder B, a path P2 in which the right cam rod 66 moves as a bobbin B moves downward along the outer shell S to be removed from the bobbin holder, a path P3 in which the right cam rod 66 moves as a new bobbin B is slid upward along the outer shell S for positioning on the bobbin holder, and a path P4 in which the right cam rod 66 moves as the bobbin B is released to slide downward along the outer shell S for positioning on the bobbin holder by the pawls 50 and 51.
  • the path P1 is best seen in FIG. 4, and it will be seen that the island member 71 serves to impart an oscillatory rotational motion to the right cam rod 66 as the wedge member C moves upward.
  • This motion in path P1 serves to permit the right cam rod 66 to move upward past the island member 71 into a position above the island member 71 where upward motion of the right cam rod 66 and of the wedge member C is checked by a finger 72 extending downwardly toward the island member 71.
  • This serves to limit the upward motion of the sleeve R and the bobbin B along the outer shell S of the bobbin holder as the bobbin B is being moved upward for release from the bobbin holder.
  • the operating means alternately allows the pawls 50 and 51 to retract into bobbin-releasing position and pivots the pawls 50 and 51 outwardly into bobbin-holding position in response to repeated upward and downward motions of a bobbin B relative to the outer shell S.
  • the point at which the cam rod 66 is checked by the wall 76 and the point at which the cam rod 66 is checked by the finger 72 are in the same plane transverse to the longitudinal axis of the outer shell S, these upward and downward motions are identical regardless of Whether a bobbin B is being placed on or removed from the bobbin holder.
  • the spring 14 urges the wedge member C between the lands 58 of the pawls 5t and 51 so that the pawls 50 and 51 are effectively locked in bobbinholding position regardless of the extent to which they are extended, it will be understood that the spring 80 may be omitted. This is because the weight of the wedge member C is alone sufficient to force the pawls 50 and 51 to pivot outwardly and to be held in bobbin holding position. It will also be understood that other operating means may be employed alternately to retain the wedge member C in an upward bobbin-releasing position and to release the wedge member C for wedgiing the pawls S0 and 51 into bobbin-holding position. lit will be further understood that many variations may be made in the embodiment herechosen for the purpose of illustrating the present invention without departing from the scope thereof as defined by the appended claims.
