Definitions

  • the present invention refers to carriers for braiding machines, and more particularly to devices for providing a practically constant tension of the thread fed by the spool on the carrier.
  • One of the objects of the present invention is to provide a carrier for braiding machines in which the thread tension is kept at a practically constant value by a thread tension member the travel or displacement of which is particularly reduced.
  • Another object of the invention is to provide a. carrier for braiding machines in which the danger of breaking the thread due to friction with the thread tension member or the sudden variation of thread feeding rate is considerably reduced with respect to the known carriers.
  • Still another object of the invention is to provide a carrier for braiding machines in which the friction caused on the thread by the thread tension member can assume different rates in correspondence to different positions of the thread tension member depending upon the thread tension.
  • Another object of the invention is to provide a carrier for braiding machines having a particularly reduced height owing to the reduced stroke of the thread tension member.
  • Fig. 1 is a front view of a carrier according to the invention
  • Fig. 2 is a sectional view of Fig. 1 through line II1I;
  • Fig. '3 is a sectional view of Fig. 2 through line III-III;
  • Fig. 4 is a sectional view of Fig. 2 through line
  • Fig. 5 is a plan view of a detail of Fig. 1;
  • Fig. 6 is a fragmentary modification of Fig. 1;
  • Fig. 7 is a front view of another form of carrier according to the invention.
  • Fig. 8 is a'fragmentary view of the former with the thread tension member in a difierent DQSition; r
  • Fig. 9 is a plan view of a detail of Fig. '7.
  • the carrier shown in Figs. 1 to '5 comprises a base I having a vertical spindle 2 and spaced vertical short and long standards 3 and 4, respectively.
  • a sleeve 5 is mounted for rotation on the spindle 2.
  • the sleeve 5 has a flange 6 on its lower end, said flange having four radial pro-, jections or teeth, Iconstituting a Tratchetwheel.
  • a spool 8 havingthread 9 is mounted on the a hole therein to accommodate the standard 4.
  • member I I consisting of a strip of spring metal providing a V shape main resilient portion II with lateral upper and lower end portions.
  • the upper end portion of the member II has a slot I2 which receives the upper flattened extremity I3 of the standard 4, said upper end portion being entered in notch I3 in the standard 4, and being held therein by reason of the resiliency of the member II and the fact that the portion II-' bears on the standard 4 as shown in Fig. 1.
  • a hole I4 in the upper end portion of the member I I serves as a thread guide in a manner to be explained.
  • a slide I5 disposed below the block I 0 is arranged for up and down movement on the standards 3 and 4.
  • a helical spring I6 surrounds the standard I4 interposed between the block I Ii and the slide I5.
  • the slide I5 has two thread guides or hooks I1 and I8.
  • a hole I9 in a depending lug 20 on the block serves as a third thread guide.
  • the block II] has a hole therein to slidably accommodate a vertical rod 2
  • carries a thread guide or hook 24.
  • is received in a hole 25 in the base I.
  • a latch 26 is formed on the rod 2
  • the latch 26 is disposed between and acted on by wings 21 on the spindle 2.
  • the latch 26 cooperates with the projections I on the flange 6 when the rod 2I is moved upwardly by the spring 22, and said latch is disengaged from cooperation with the projections I when the rod 2
  • the thread 9 fed from the spool passes through the hole I9, then through the thread guides I1, 24, I8 and I 4 to the braiding which is beingmade.
  • the slide l5 recovers the excess of thread length during the operation of the carrier and its displacement is the half of the. variation of the thread length, due to the path of the thread as shown.
  • FIG. 6 shows a variation of the arrangement of the thread guide 24.
  • the position of this thread guide is below the uppermost position of the thread guides I1 and l8, so that, when the slide l5 rises due to the tension of the thread, the thread guide 24 is relieved from the thread and rises under the action of the spring 22; with this arrangement, of course, the position of the latch 26 on the rod 2
  • the carrier represented by Figs. '7 and 8 differs from the former ones in that the rod 2
  • the friction on the thread which has left the guide 24', is consider ably diminished and the thread tension overcomes the brake resistance.
  • the brake device consists of a sleeve 28 loose on the standard 4 and bearing a shoe 29 urged against the thread on the spool 8 by the action of a torsion spring 30 one end of which is fixed to the sleeve 28 and the other end is fixed to a crown bush 3
  • a torsion spring 30 one end of which is fixed to the sleeve 28 and the other end is fixed to a crown bush 3
  • engages a projection 32' of a plate 32 dovetailed in the top portion of the standard 4 so that the torque of the crown bush urges the plate 32 into engagement with the standard 4, while the plurality of such indentations affords a quick and easy means for obtaining an accurate regulation of the braking action through the spring 30.
  • Said spring 30, being both under compression and torsion provides for the braking force, keeping the crown bush 3
  • the plate 32 is provided with an eyelet 33 actingas the final thread guide.
  • a thread spool spindle mounted on a base, a standard on said base, a slide on said standard having two thread guides, three thread guides supported by said standard, for guiding the thread said thread passing through the first of said three guides, then through the first of said two guides, then through the second of said three guides, then through the second of said two guides, and then through the third of saidthree guides, and resilient means cushioning the upward movement of said slide.
  • a thread spool spindle mounted on a base, a standard on said base, a slide on said standard having two thread guides, and three thread guides carried by said standard one of which is positioned below said first mentioned thread guides when said slide is in its uppermost position, and resilient means cushioning the upward movement of said slide.
  • a thread spool spindle provided with a ratchet and mounted on a base, a standard on said base, a slide on said standard having two thread guides, three thread guides supported by said standard, said thread passing through the first of said three guides, then through the first of said two guides,
  • a thread spool spindle provided with a ratchet wheel and mounted on a base
  • a standard on said base a slide on said standard having two thread guides, three thread guides supported by said standard, said thread passing through the first of, said three guides, then through the first of said two guides, then through the second of said three guides, then through the second of said two guides, and then through the third of said three guides, two of said three guides being fixed on said standard and the third being slidable in a direction parallel to said standard
  • a spring actuated latch to engage said ratchet wheel and connected to said slidable guide, the tension of the thread acting on said last mentioned guide to disengage the latch from the ratchet wheel.
  • a thread spool spindle provided with a ratchet wheel and mounted on a base
  • a standard on said base a slide on said standard having two thread guides, three thread guides supported by said standard two of which are integral therewith and the third being slidable in a direction parallel to said standard
  • a spring urging said slidable guide upward to a position below said first mentioned thread guides when said slide is in its highest position
  • a latch operatively connected with said slidable thread guide and engaging said ratchet wheel when said slidable thread guide is moved down by the thread.
  • a thread spool spindle provided with a ratchet wheel and mounted on a base, two vertical rods on said base having different lengths, a piece resting on the end of the shorter standard and provided with a hole for the longer standard, a slide having two thread guides and sliding on said standard below said piece, helical springs on said standards between said piece and said slide for urging the latter downwardly, two thread guides supported by said piece one of which is vertically slidable with respect to said piece, a spring urging said slidable guide upwardly, a latch connected to said slidable guide and cooperative with said ratchet wheel, and a resilient member engaging the longer standard above said piece and comprising a further thread guide.”
