Definitions

  • a known solution to this problem consists in providing on the sewing machine, either near the table thereof or as a substitute for the bobbin carrier spindle, a vertical or slightly inclined rack supporting a plurality of bobbin spindles (as in the case of the device shown and described in the US, Patent No. 2,940,685 of June 14, 1960 to Glass). Now admittedly this solution proved to be as unsatisfactory as the one mentioned hereinabove; in fact, when the bobbin spindles are disposed in a vertical or slightly inclined plane, the threads are not prevented from depending by gravity and engaging each other until they become entangled.
  • the bobbin carrier rack according to this invention which comprises two parallel lateral members, a plurality of bobbin-supporting spindles or pins having one end pivotally connected to one of said lateral members and resting with the other end in a corresponding notch formed in the other lateral member, each spindle being movable angularly in a vertical plane from a horizontal position to a vertical position, is characterized in that said pivotal connection is disposed externally of the lateral member provided therewith in relation to the other lateral member, and that a stop is formed above each pivotal connection with a view to limit to a substantially vertical position the permissible angular movement of the spindle from its horizontal position.
  • FIGURE 1 is a perspective view of a rectilinear-type bobbin rack disposed at the end of a sewing-machine table;
  • FIGURE 2 is a cross-sectional view of the rack shown in FIGURE 1;
  • FIGURE 3 is a diagrammatic plan view from above of a circular track
  • FIGURES 4 and 5 are diagrammatic views showing two different mountings of the circular rack of FIG- URE 3.
  • the rack according to this invention comprises a pair of parallel lateral members 1 and 2 which are either rectilinear (FIGURE 1) or circular (FIGURE 3).
  • the bobbin supporting spindles 3 are pivotally mounted on one of these members, for example member 2 in the example illustrated.
  • spindles are movable from a substantially vertical position A, in which the bobbin 4 can be slipped thereon, to a substantially horizontal position B in which the free end of spindles 3 engages the top edge of the other lateral member 1, or corresponding notches 1a formed at spaced intervals along this edge.
  • the lateral members 1 and 2 consist of the parallel wings of a U-sectioned element, the wing in which the spindles are pivotally mounted having an outer extension 5 bent at right angles thereto which can be used for securing the rack to the top or bottom surface of the table T of the sewing machine.
  • each spindle is extremely simple and may be as follows:
  • each bobbin spindle or pin 3 has a small diametral hole formed through one of its ends.
  • a fixed pivot pin 6 disposed externally of and parallel to the lateral member 2 is fitted through the holes of the different spindles to constitute a hinge pin.
  • all the pivot pins 6 may consist of a single member such as a steel wire welded at two or more points along the lateral member 2.
  • the angle notch 2a is so dimensioned that its upper bottom 2b acts as a stop to the spindle 3 when the latter is raised to its vertical position A, a preferred arrange- 3 ment consisting in so positioning said bottom 2b that when the spindle is erected it lies slightly beyond the 90-degree position A illustrated.
  • FIG. 3 the circular form of embodiment (FIGURE 3) is advantageous with a view not only to keep a greater number of bobbins in a relatively reduced space, but also to facilitate the quick laying and removal of the bobbins.
  • the circular rack is rotatably mounted on a central pivot pin 7 consisting either of the conventional bobbin spindle extending through its base (see FIGURE 4), or of a pin rigid with a support or base member, an alternative arrangement consisting (FIG- URE 5) in securing this rack by means of a screw 9 to the top or bottom surface of the table T of the sewing machine.
  • a rack for supporting the under-thread bobbins of sewing machines which comprises two parallel members, bobbin spindles having one end pivotally connected to one of said members and bearing with their other end in a notch formed in the other member, said spindles being each adapted to pivot in a vertical plane from a substantially horizontal position to a substantially vertical position and vice versa, the means for pivotally connecting each spindle to said one member disposed externally of said one member with respect to the other member parallel thereto, and stop means to limit the permissible angular movement of said spindles.
  • said one member supporting said connecting means has an outer extension bent at right angles thereto, that is in a direction opposed to said other parallel member, said one member having notches formed therein which extend on either side of the corner between said one member and said extension, the bottom of said notch which lies in said extension constituting said stop means for limiting the vertical bobbin-receiving position of said spindle in order to retain said spindle in this position during the insertion and removal of the bobbin on and from said spindle.
  • said pivotally connecting means consists of a pivot pin extending through a transverse hole formed in the spindle portion projecting externally of said one member.
