Definitions

  • Bent wires operating as releasable latching pawls normally prevent the needles from moving forwards relative to the pulling buckle when the latter is urged through the ground web.
  • a tongue of a releasing tube engages the ground web, so that the releasing tube removes the latching pawls from their locking position thus automatically permitting the needles to carry out their stroke relative to the pulling buckle. All the operations of the apparatus can accordingly be controlled by merely moving the handle of the apparatus to and fro.
  • This invention relates to the apparatus for the manufacture of long-pile rugs by knotting pile tufts consisting of strands of an extra yarn in a fabric constituting a ground web of the rug and, more particularly, to apparatus comprising a first unit including pulling means which can be set in a predetermined position behind a thread of the ground web by passing said pulling means on one side of said thread, a second unit movable in a predetermined manner relative to said first unit and including pushing means passing on the other side of said thread and reaching a well determined position with respect to said predetermined position of said pulling means when said second unit is moved in said predetermined manner, and actuating means for causing said second unit to move in such predetermined manner.
  • Patent 2,873,766 serve to make Ghiordes or Turkish knots by means of strands of an extra yarn previously cut at a predetermined length.
  • Some of these apparatus have a first unit including a pulling buckle usually made of metal. This buckle can be inserted between two portions, for instance, of warp threads, which are comprised between two weft threads of an open-worked fabric constituting the ground web of the rug.
  • the pulling buckle is carried by a head-piece on which a strand of an extra yarn can be set in a predetermined position.
  • a rod is moreover rigidly fixed to the head-piece on the side thereof opposed to that carrying the buckle.
  • the second unit of these known apparatus includes a support arranged for sliding motion along the rod of the first unit.
  • Two needles are pivotally mounted on said support. These needles are guided by grooves provided in the head-piece of the first unit. At rest, the forked ends of these needles are fully retracted and they lie within the head-piece 0f the first unit where they are ready upon sliding the needle support along the rod of the first unit to catch the two ends of the strand of extra yarn set on the head-piece.
  • the needles are guided in such manner by this head-piece that, at the end of the forward stroke of the second unit along the rod of the first one, the forked ends of the needle cross each other within the pulling buckle of the first unit.
  • the middle portion of the strand of extra yarn thus lies on the two warp thread portions of the fabric between which the pulling buckle has been inserted and the ends of this strand extend under these two threads on the other side of the fabric. Since the needles cross each other within the pulling buckle of the apparatus, the two ends of the strand of extra yarn lie both in this pulling buckle. Upon removing the apparatus from the ground web, these two strand ends are consequently pulled through the ground web by the buckle and they pass now between the two warp threads between which the pulling buckle had been inserted, thus forming the Ghiordes knot around this pair of warp threads.
  • Other known apparatus of the same kind comprise a first unit including a pair of identical pulling buckles which are mounted for rocking motion relative to each other about a common axis lying in the plane of the buckles so that these two buckles can be either rocked into a position in which they lie against one another or move away from one another like scissors.
  • the second unit of these known apparatus also includes a pair of needles. These needles do, however, not cross each other, but they extend in parallel.
  • the operation of these known apparatus is similar to that disclosed hereabove.
  • the two buckles of the apparatus are inserted together between two thread portions, for instance of the warp of the ground web, while these buckles are lying against each other.
  • Still further known apparatus of the same type comprise a first unit including two fixed buckles arranged side by side, each of which can be inserted under a thread portion of the ground web. These buckles are bent in such a manner that when they have been inserted each under one thread portion of the ground web, their ends extend upwards above the ground web.
  • the second unit of these apparatus includes two parallel needles, each forked end of which enters one of the buckles when the second unit comes at the end of its forward stroke relative to the first one. The needles thus cause the ends of the strand of extra yarn to pass over the two thread portions of the ground web under which the buckles of the apparatus have been inserted.
  • All these known apparatus comprise two control members, one for each unit of the apparatus.
  • a first control member usually consists of a handle which belongs to the second unit of the apparatus.
  • the second control member consists of a button secured to the end of the rod of the first unit, which extends throughout the handle and on which the latter is mounted for shifting motion.
  • the apparatus In order to urge the buckle or buckles of the apparatus through the ground web, the apparatus has to be held in such manner that its control button remains in contact with the handle.
  • the second unit is moved alone relative to the first one by releasing the button and prosecuting the forward motion of the apparatus only with the handle.
  • a pulling action need only be exerted on its handle. This pulling action first causes the handle to move back alone until it butts against the button while returning the needles of the apparatus into their resting position and then he buckle or buckles to be removed from the ground web.
  • a more particular object of the invention is to improve the apparatus disclosed in my previous Patent 2,873,766 by additionally providing the same with releasable latching means inserted between said first and said second unit for normally preventing said second unit from moving relative to said first unit under the control of said actuating means, and with releasing means operatively connected to said latching means for removing the same from their locking position and permitting said second unit to move in said predetermined manner with respect to said first unit, said releasing means including a releasing member engaging the ground web when said pulling means reach said predetermined position, thereby causing the releasing means to remove the latching means from their locking position.
  • FIGURE 1 is an elevational partly sectional view of the apparatus in a first working position
  • FIGURE 2 is a view similar to that of FIGURE 1 showing the apparatus in a different working position;
  • FIGURE 3 is a side view partly in section
  • FIGURE 4 is a cross-section along line IVIV of FIGURE 3.
  • the apparatus represented in the drawing comprises a first unit including a head-piece 1 which is secured to a rod 2 and carries a buckle 3.
  • a second unit movable with respect to the first one comprises a slide 4 made in one piece with a handle 5.
  • Two needles 6, 6a are pivotally mounted on slide 4. Needles 6, 6a are guided by grooves 7 provided on head-piece 1; they are held within these grooves by pins 8.
  • the shape of the needles 6, 6a and that of the bottom of the grooves 7 as well as the position of pins 8 are chosen so that the forked ends of needles 6, 6a enter the buckle 3 and cross each other within this buckle when slide 4 is shifted along rod 2 towards headpiece 1 from the position represented in the drawing.
  • the sizes of the apparatus are moreover chosen so that, on the one hand, the buckle 3 can be inserted between threads 9 and 10, for instance of the warp of an open-worked fabric or ground web, and, on the other hand, the needles engage the fabric between threads 9 and 11, 10 and 12, respectively, when slide 4 is moved toward head-piece 1.
  • Openings 13 are provided on head-piece 1 so that a strand 14 of extra yarn can be set thereon in a predetermined position.
  • the apparatus moreover comprises a latching device which is inserted between the two described units.
  • This latching device comprises a pair of latching pawls consisting of spring wires 15.
  • Each wire 15 is bent in such manner as to comprise a straight portion 15a extending within a longitudinal groove 16 of rod 2, a bent end portion 15b which is perpendicular to the straight portion 15a and enters a bore provided across rod 2, a camming portion which extends obliquely away from rod 2, and a locking portion 15d extending toward and in a direction approximately perpendicular to rod 2.
  • the latching device also comprises a releasing member consisting of a tube 17 coaxial to rod 2 and to handle 5. This handle together with slide 4 are mounted for shifting motion on tube 17.
  • Tube 17 Two diametrically opposed longitudinal slots 18 are provided in tube 17. In the position shown in FIG. 1 the camming portions 15c and the locking portions 15d of wires 15 extend through slots 18. Tube -17 is finally made integral with a tongue 19 extending throughout head-piece 1 (FIGS. 3 and 4). Tongue 19 protrudes in front of head-piece 1 when the second unit of the apparatus is in resting position as shown in FIG. 1. If this second unit has been removed from its resting position, a return-spring 20 located in handle 5 and bearing, on the one hand, on the bottom of this handle and, on the other hand, on the upper end of tube 17 urges the second unit toward its resting position which is determined by a stud 21 secured to slide 4 (FIG.
  • wires, 15 are in the position represented in FIG. 1. Their locking portions 15d extend under slide 4 so that a thrust the apparatus. Wires 15 thus prevent one unit of the apparatus from moving relative to the other one when they are in the position represented in FIG. 1. In this workting position of the apparatus, buckle 3 may therefore be inserted into the ground web of the rug, whatever may be the resistance opposed by the latter, upon acting only on the handle of the apparatus.
  • the front end of tongue 19 happens to engage the ground web at the precise stage of the operation, which is shown in FIG. 1.
  • the engagement between tongue 19 and the ground web can occur indifierently either with the threads 9 and of the warp or with one of the weft threads (not shown) which extend at both ends of the warp thread portions 9 and 10, between which buckle 3 is just being inserted.
  • a continued thrust exerted on handle 5 in the direction of the ground web has as a result to cause the apparatus to pass from the working position shown in FIG. 1 to that of FIG. 2 in which buckle 3 has reached the predetermined position in which it has to be brought with respect to the ground web.
  • the apparatus makes then a Ghiordes knot around the thread portions 9 and 10 of the warp under the same conditions as the known apparatus.
  • Needles 6, 6a push the ends of strand 14 between thread portions 9 and 11, 10 and 12, respectively, of the ground web and bring them into buckle 3 at the end of the forward stroke of slide 4, i.e. when slide 4 butts against head-piece 1.
  • Handle 5 is then pulled back.
  • the apparatus returns first in the position of FIG. 2, then in that of FIG. 1 and finally buckle 3 is removed from the ground web and pulls the end of strand 14 so as to pass the same between thread portions 9 and 10 thus ending the Ghiordes knot.
  • the latching device of the apparatus described has thus the advantage that all the operations of the apparatus can be controlled by means of a single member, namely handle 5, which can, moreover, be held in any desired manner.
  • the required thrust for inserting buckle 3 into the ground web is therefore no longer produced as with the known apparatus by a single finger but by the whole forearm, which is obviously much less tiresome.
  • An apparatus for the manufacture of long-pile rugs by knotting pile tufts consisting of strands of an extra yarn in a fabric constituting a ground web of the rug comprising, in combination, a first unit including pulling means which can be set in a predetermined position behind a thread of the ground web by passing said pulling means on one side of said thread, a second unit movable in a predetermined manner relative to said first unit and including pushing means passing on the other side of said thread and reaching a well determined position with respect to said predetermined position of said pulling means when said second unit is moved in said predetermined manner, actuating means for causing said second unit to move in said predetermined manner, releasable latching means inserted between said first and said second unit for normally preventing said second unit from moving relative to said first unit under the control of said actuating means, and releasing means operatively connected to said latching means for removing the same from their locking position and permitting said second unit to move in said predetermined manner with respect to said first unit, said releasing means including a
  • said latching means include a movable latch member mounted on one of said units and having a camming surface and a projection cooperating with the other unit for normally preventing motion thereof relative to said one unit and said releasing means include a shiftable releasing member cooperating with said camming surface of the latch member thereby causing said projection thereof to release said other unit.
