Definitions

  • This invention has for its purpose to improve the operation of the aforesaid machine and the product produced thereon and to reduce the amount of manual labor required and the need for close attention on the part of the operator. More especially the improvements reside in reducing the transverse and longitudinal sag in the material, cutting the needle and bobbin threads automatically as the material leaves the machine and maintaining a constant speed ratio between the needle and the bobbins.
  • the machine is of the kind in which material to be quilted is supported on a frame for longitudinal and transverse movement relative to sewing instrumentalities of a plurality of transversely disposed sewing heads, means for effecting movement of the frame comprising a pattern and power operable means to cause the frame to follow the pattern and spaced parallel transversely disposed conveyor means on the frame adapted to grip the opposite longitudinal edges of the material to draw it onto the frame for quilting operation and after quilting to move it off the frame.

  • the secondary frame 18 supports in transversely spaced relation rails 22-22 v comprised of upper and lower channels 22a, 22b (FIG. 5)
  • Each sewing head comprises needle bars 29a and means including a drive shaft 29b for driving the same and bobbins 29c and means including a drive shaft 29d for driving the same mounted respectively on the upper and lower beams 28 and 30.
  • the frames 10 and 18 are simultaneously moved transversely and longitudinally with respect to the sewing heads by means of a pattern track mounted on the floor between the post 26-26 and a follower mounted on the frame 18 and in engagement with the pattern track, Pattern drives of this kind are old in the art and hence need not be described further herein.
  • FIG. 1. provided with wheels 42 by means of which it was moved up to the adjacent end of the frame 18 whereupon the leading end of the material was introduced between the endless conveyors 24-24. The conveyor was then started so as to grip the leading end of the material and pull it onto the frame 18.
  • the rails 22a and 22b as shown herein in FIG. 5a and in the aforesaid application are mounted on the frame 18 with the lower rails 22b fixed and the upper rails 22a yieldably supported on the lower rails.
  • the rails 22a are supported by spring s and by adjustments of adjustable screws 1, the compression in the springs s may be varied to increase or decrease the pressure between the confronting runs of the conveyors.
  • Supported in this manner the upper rails 220 are movable upwardly relative to the lower rails 22b and thus enable separating the conveyors at the entrance end thereof by raising the upper rails at that end upwardly relative to the lower rails.
  • a pneumatically operable cylinder is mounted on each of the upper rails 220-220 in a vertical position with its piston rod p extending to a position above a bracket b fastened to the lower rail.

  • converging aprons 29 and BI, FIG. 5 are provided transversely of the upper and lower rails respectively.
  • the conveyors were supported in a slightly divergent relation in the direction of movement of the material to impart transverse tension to the material, thereby to take up slack or sag.

  • a crank arm 68 is fixed to the bushing 52 and this, in turn, is pivotally connected to a piston rod 68 extending from a cylinder 70, mounted on the frame 18. Pressure supplied to the lower end of the cylinder 70 will rotate the bushing 52 in a clockwise direction to raise the bars 44-44 into operative position and pressure supplied to the upper end of the cylinder will rotate the bushing 52 in anticlockwise direction to lower the bars 44-44 out of operative position.
  • the supporting bars 44-44 are moved into operative position and at the same time operation of the conveyor means is initiated so as to hold the material without sag while it is being drawn onto the frame 18. Following clamping of the ends of the material after it is drawn onto the frame, the supporting bars are lowered so as not to interfere with the quilting operation.

  • the clamping means were manually moved into clamping position.
  • the present clamping means is automatically moved into clamping position and comprises the improvement over the aforesaid clamping means in that they apply longitudinal tension to the material simultaneously with clamping engagement therewith.

  • the upper jaws 72-72 have at their lower edges wedge-shaped portions 90 adapted to enter the grooves 92-92 in the lower jaws when the jaws are rocked from their inoperative position shown in dotted lines, FIG. 4, to their operative position as shown in full line to grip and draw the opposite ends of the material away from each other thus imparting longitudinal tension to the material at a time when the supporting bars 44-44 are holding the material in a substantially flat plane.
  • the jaws 72, 74 are moved into clamping engagement with the ends of the material at the termination of forward movement of the material by means of the conveyor means and following clamping of the ends of the supporting bars 44-44 are lowered to their inoperative position.
