Definitions

  • a thread bobbin stand having a stand attached on a base plate.
  • the stand is a rectangular frame with two long and two short sides standing on one of its short sides.
  • Holders for the thread bobbins are arranged on one longitudinal side and thread passage openings are arranged in the opposite longitudinal side for guiding the thread running off a bobbin.
  • the center axes of the thread bobbins are directed towards its associated thread guiding opening and a thread clamping device is arranged adjacent each thread guiding opening.
  • the thread clamping device on one hand serves for cutting off the thread and on the other hand for retaining the end of the thread cut off.
  • Sewing machines for industrial purposes have hitherto been provided with thread bobbin stands in the shape of a plate, this plate being provided with vertically arranged holdersmostly in the shape of shaft ends for the thread bobbins or cones and the plate has been in the shape of a circular disk having at its centre a rod with a yarn guide at the upper end.
  • a thread holder makes it possible to arrange only rather few, generally only two thread bobbins for the reason that a greater number of bobbins would require disks having a considerably greater diameter. Consequently, when changing the thread, e.g. for change of color or for changing to a new type of yarn the operator has to remove one bobbin and to put on a new one which is a rather time wasting work.
  • the object of the present invention is to eliminate the drawbacks recited in the aforegoing with regard to thread bobbin stands in particular intended for sewing machines in clothing producing workshops and comprising a stand attached to a base plate.
  • the main feature of the invention is to be seen therein that the stand comprises a rectangular frame standing one one of its short sides, one longitudinal side of said stand provided with holders for the thread bobbins (so called cones), the opposite longitudinal :side provided with passage openings for guiding the thread coming from the thread bobbin in question.
  • the axes of the thread bobbin holders are according to the invention directed towards their associated thread guiding openings and in the vicinity of each thread guiding openings there is arranged a thread clamping serving on one handfor cutting off the thread and on the other hand for retaining the end of the cut off thread.
  • the thread clamping devices comprise with advantage resilient metal blades being preferably arranged just above the thread guiding opening and being each provided with a border ground to a cutting edge so as to facilitate the cutting off the thread.
  • FIG. 1 is a side elevation of the thread bobbin stand shown in combination with a sewing machine being indicated only diagrammatically
  • FIG. 2 is a front view on an enlarged scale, of the thread bobbin stand
  • FIG. 3 shows on an even more enlarged scale a front view of a thread bobbin holder and a thread guiding opening
  • FIG. 4 is a partly out side elevation corresponding to FIG. 3.
  • the thread bobbin stand comprises a base plate 1 and a stand 2 attached to the base plate 1.
  • the stand 2 comprises a rectangular frame manufactured from e.g. metal rods or the like and the stand 2 is with one of its short sides 4 attached to the base plate 1.
  • One longitudinal side 5 of the frame 2 is provided with holders 6 for the thread bobbins 7, so called cones.
  • the other longitudinal side 8 of the stand is provided with passage openings 9 for the thread 10 coming from the thread bobbins 7. So as to facilitate the running of the thread through the opening 9, these openings 9 are preferably provided with an eye of a ring 11 of a suitable material, with advantage of porcelain.
  • the holders 6 are mounted with such an inclination that the axes 17 of the thread bobbins 7 arranged on the holders 6 are directed towards the thread passage openings 9. Due to this inclination the thread coming from the bobbins will all the time enclose the same angle with the axis of its bobbin and one obtains. thus, essentially the same friction at the running off of the thread which thus will run smoothly with an equal tension. Simultaneously, any risk is eliminated for entanglings of the threads. Of course, this angle will diminish as the thread is used up but during one running off turn this angle can be considered as constant and its diminishing from one turn to the next is very small.
  • the thread 10 runs from the thread guiding opening 9 over a thread holder 12 to a sewing machine 13.
  • each thread passage opening 9 there is arranged a thread retainer 14 shown on an enlarged scale in FIGS. 3 and 4.
  • this thread retainer comprises a resilient metal blade 15 fixed to the stand portion 8 by means of a screw 16. So as to facilitate the clamping of the thread between the blade 15 and the stand portion 8 the upper end portion 17 of the blade 15 is bent outwards.
  • one border of the blade 15 is ground in such a way that it forms a cutting edge which facilitates the cutting off of the thread 10.
  • a thread bobbin stand as being provided with one single bobbin holding device but it is of course possible to arrange many stands side by side on one single base plate 1. Further, it is also possible to arrange two stands 2 on each base plate and when there is then required an increase of the number of stands there could be arranged, side by side, many plates each carrying two stands.
  • a base plate comprising a circular disk having annularly arranged stands in which case each disk should be rotatable and lockable in the desired position in such a way that, by means of a rotation, it will be easy to bring the stand carrying the desired thread bobbins to operation position.
  • the stand is provided with five bobbin holders 6 but this number is of course independent of the invention. Too great a number of holders 6 should, however, cause the stands to be too high for practical use.
  • the stand described in the aforegoing and shown in the drawings is supposed to be manufactured from metal rods or tubes and in such a case it is of importance to arrange porcelain eyes 11 so as to spare the threads.
  • the stand may, partly or completely, be manufactured from another material.
  • thread retainers 14 may be shaped otherwise than as a metal blade as it could be shaped as a thread eye or a circular disk having a sharp outwardly bent border and being fixed to the stand by means of the screw 16.
  • shaft ends 6 could be arranged to carry a central cone e.g. manufactured from synthetic resin for fitting the sleeve on which the thread of the bobbin is Wound.
  • a thread bobbin stand adapted to be used in particular on sewing machines in Workshops in which clothings are manufactured, a base plate, a stand attached on said base plate, said stand comprising a rectangular frame comprising two long and two short sides and standing on one of its short sides, holders for the thread bobbin arranged on one longitudinal side of said frame, thread passage openings arranged in the opposite longitudinal side of said frame for guiding the thread running off a bobbin, the centre axes of said thread bobbins directed towards its associated thread guiding opening, a thread clamping device arranged in the vicinity of each thread guiding opening, said thread clamping device on one hand serving for cutting off the thread and on the other hand for retaining the end of the thread cut off.
  • said thread guiding opening provided with a means for reducing the friction of the thread and for eliminating any risk for unintentional tearing of the thread.
  • said thread guiding opening provided with a porcelain ring for reducing the friction of the thread and for eliminating any risk for unintentional tearing of the thread.
  • said thread clamping device comprising a metal blade.
  • said thread clamping device comprising a metal blade, having a ground edge serving as a cutting edge for severing the thread.
  • said thread bobbin holding device comprising a shaft end.
  • said thread bobbin holding device comprising a shaft end, provided with a centre cone.
