Definitions

  • the invention relates to a bobbin orv braiding already been proposedlin the eighties: of the prew:
  • the plate notches which receive the stemsof the bobbin carriers similarly as in thecase ofthe old Malhere machine in. Which the plates were arranged in a straight line, are arranged symmetrically to the longitudinal and transverse centre lines of the plateseachof which forms a rigid. whole. They differ however from the previous machines having bobbin carriers with elongated stems in thatthenotches are longer than thestems of" thebobbin carriers and their shock. over .the gaps. which are .presentjat the:
  • edges are curved in the form of an arc in such a manner that their end portions have the same radius of curvature as the side surfaces of the elongated stems.
  • the notches are at the same time so arranged that the end portion of a notch which, when the driving plate is stationary, lies on the inside of the machine forms a direct continuation of the circular periphery of the adjacent plateand therefore a'continuation of the edge of the aperture ofthe track plate which is in contact with it.
  • the points of the track plate lying on the outside of themachine, 'at the places where the bobbins are movedfrorhthecrossihg plate of the track towards the outside are blunted or shortened in the manner which has become known in the case of machines with circular stems, so that they do not project between the adjacent end edges of the notches inthe plates.
  • the elongated stems of the bobbin carriers do indeed nolonge'r'fit closely over their entire lengths in the plate notches and a close fit to the edges of the notches only now takes place at the ends of these edges'over about half the length of the lateral surfaces of the stems. This is, however, quite s'ufiicient for theregular guidance and movement of *the bobbin carrier.
  • the bobbin carrier stems are positively guided'by the edges of the notches in theplates-until the point which is in front in the direction of movement has passed the blunted point of 'the track plate and the further guidance can then be undertaken by the aperture in the track plate.
  • thenew machine is'oonsiderably simpler and cheaper than the known bobbin machines with elongated stems and plates arranged in a circle, since undivided rigid plates are employed.
  • the new machine is also simpler than theknown bobbin machines having bobbin carrier with circular stems, since, the guidingpieces, which are regulated with the coupling sleeves of the driving plates, necessary in these m'achinesfor bridging over the gaps in'the bobbin carrier guidance on the outside of the machine are entirely dispensed with. It also possesses the advantage over these machines that the arrested bobbins in the plate notches have only relatively little play.
  • the upper part and the lower part of the'bobbin carrier are: relatively rotatable, as the upper part which carries the bobbin and the thread guides needs to make no rotation during the movement of the bobbin carrier over the track.
  • the upper part has hitherto been revolubly mounted by means of a sleeve on a vertical pin on the upper foot disc of the bobbin carrier, for
  • the bobbin carriers for the machine have elongated stems 19 of lens-shape [or double angled cross-section. These stems are of a slightly less length than the length of the'notches 16 in the driving plates 3. Theirtwo lateral surfaces are curved to a single arc, the radius dof which corresponds to the radius of the driving plate. Thus theirlateral surfaces fit the arcs a and b of the notches in the driving plates, in sucha manner that each lateral surface of a bobbin stemis in close contact for about half its length with one end portion of the edges of the notches in the driving plates and can be closely guided for about half the length of thestem asmay,be seen from Fig. l. 3 a g g In Fig. 1. the greater part of the driving plates 3 is illustrated in the position of rest. The bobbin carriers located between the stationary plates are thus arrested at the crossing places ofthe track. Since the notches l6; in the plates are somewhat larger thanthe elongated stems 1 9,
  • the bobbin carriers in their position of rest, have some play in the notches. This however is without effect on the guidance of;the bobbin carriers on their further movement.
  • the stems of the two bobbin carriers to be .movedbythis plate abut with both lateral surfaces for about half the length of these surfacesbothagainst the edges of the notches-of the rotatingplate and also against the edges of the. notches of .thetwo adjacent stationary plates. Therefore, as illustrated in full lines on the right hand side of Fig. 1 they are so adjusted that the points which are front in the direction of motion are directed onto the part of the track belonging to the rotating plate and are thus positively guided into the desired part of the track.
  • the bobbin carrier which moves to the inside of the machine has moreover anuninterruptedguidanceatthe edge of the ngtch in the stationary'plate. At. the outside of the machine this guidance is indeed lacking. At this place, however, owing to the. fact that therear half in the direction of motion of its elongated stem 19 is in close contact on both sides with the notches in the driving plates the bobbin carrier is positively guided by the plates themselves into the correct position, until its point which is in front in the. direction of motion has passed the shortened point 17 of the track plate and the bobbin carrier can now be properly guided by the aperture in the track plate. (See the posi tions illustrated at the right-hand side of Fig.
  • the bobbin carriers with elongated stems employed in the machine are so constructed that the carriers are able to rotate with their feet in the elongated stems.
  • the feet of the bobbin carrier in accordance with Fig. 4-6, consists of two foot discs 20'and 21 and a cylindrical pin 22 which combines these andis formed in one piece with the two discs 20 and 21; Between the ,two'foot discs there are arranged one above the other two plates 23, 24, the similar outlines of which correspond to the desired outline, of the. elongated stem 19.
  • the two .plates 23 and 24- each possess an aperture or slot 25, 26 respectively, which is open to one side, and is boundedon the inner end by circular are.
  • the two plates 23,: 24 am then'fixed together in superimposedposition, preferably by means of two rivets 2'7, which are introduced in corresponding holes in the two plates.
  • the two foot discsr20 and 21 are provided with.
  • holes 28 which-coincide with the holes in the, plates 23, 24 and are of such a size as to allow the passage both of the shanksof the rivets and'alsoof the riveting tools.
  • the thicknessof: the twoplates 23, 24 and the width of their apertures 25-, 26 is so selected that the plates are guided on'the foot of the bobbin without play but are'able to turn easily'about the pin 22. Since the-open ends of the two apertures 25,. 26 in the plates 23 and 24 are located in the finished bobbin-carrier foot in opposite sides of the elongatedstem, there is obtained, in spite of, the presence of these apertures on each side, a slidingsurface which extends over the entire length of the stem.
  • the holes in the. foot discs of the bobbin carrier can also advantageously be used for lubricating the surfaces of the elongated stem which slide on the foot discs-20, 21.-
  • the upper footdisc 2,01 carries on its upper side the sleeve 29, which also forms one, piece with the foot, for the insertion of. the end of the spindie of; the upper part 30 of the 'bobbincarrier.
  • the ⁇ sleeve ;29-canin some cases be replaced by a pin over which the upperv part of the bobbin carrier is placed: I U
  • the machine may be a right-handed and lefthanded machine, that is to say it maybe so arranged that each driver can be rotated clockwise or anti-clockwise asdesired;
  • each driver can be rotated clockwise or anti-clockwise asdesired;
  • carriers considerably more advantageous than the known arrangement of circular stems in such machine since the bobbin carriers can be faultlessly guided and driven in both directions of rotation.
  • the outer track plate points 17 and 17a areall shortened or blunted asamovement of the bobbin fromthe track crossing to the outside can then take place at all places.
  • the arrangement may also be such that the clutches are moved in the direction of disconnection by power conserving meansyfor example springs.
  • its arrangement may be the reverse of that-illustrated, that is to say it may be such that the clutches are located in the disconnected condition in an upper end position and are moved downwards for the purpose of connection.
  • the fixing of the driving plates 3 in the position of rest can then be effected, as known, by lugs provided on the-regulating forks of the clutches '7 which engage in recesses on the under side of the drivingplate'.
  • the bobbin carrier illustrated can also be 'modifled in that the two plates 23, 24 whichform the elongated stem 19, instead of being connected together by rivets, can be connected by point welding.
  • the fixed: connection oil-the two plates can be dispensed with-since they are secured against becoming loose from the foot of the bobbin carrier by the guidance on the foot'discs and by the guidanceontheiedges of theiapertures in the driving plate and the trackplate.
  • the elongated stem may .alsobe made in one piece. In this case it can consist of a perforated plate which is inserted axially in the pin in the foot of the bobbin carrier iii-which case the foot of the bobbin :carrier must of course be in two parts.
  • the one-partplate which forms the stem can, by means of .an aperture which re ceivesthe pin and is 0128111101). one side, be pushed sideways between the foot plates. In this; case also, as in the case of thearrangementcof the plates which are not connected together, there is the advantage of easy interchangeability oithe elongated stem. 1 e 1 In combination with the new: machine iii-some cases alsothe known bobbin carriers ,with elon-. gated stems in which the upper part is revolubly mounted on the foot of the bobbin carrier canbe employed. r
