Definitions

  • the present invention relates to a control device, especially for a sewing machine whereby stitches forming various patterns .can be produced automatically, and wherein at least one of the two effective elementsneedle bar and work feed device-is subjected to the action of said control device which is intended to locate the exact position at which the needle penetrates the work.
  • This control device comprises a digital programme controller furnishing electric signals, a series of electromagnets to which the said signals are transmitted, a series of mobile abutments controlled by the said electromagnets and each adapted to occupy two positions, a withdrawn position and a working position, and finally a slidable control member which is connected mechanically tothe said element--needle bar or work feed device-and is subjected to the action of a driving member which displaces it in the one or the other direction, the said control member comprising arresting surfaces with which the aforesaid mobile abutments cooperate and which are so arranged that each mobile abutment determines two stopping positions of the control member depending on whether the latter has come into contact with the abutment when being displaced in one direction or the other.
  • FIGURE 1 is a sectional view of part of a sewing machine, showing only those elements which are necessary for the understanding of the invention.
  • FIGURE 2 is a plan view of a detail of FIGURE 1, on a smaller scale.
  • FIGURE 3 is a plan view of a further detail of FIG- URE l, likewise on a smaller scale, and,
  • FIGURE 4 is a diagrammatic elevational view of a detail of a modified form of embodiment.
  • the machine illustrated comprises a needle 1 fixed to a needle-carrying bar 2, which itself is mounted in a cradle 3.
  • the latter is articulated on a pin 4 belonging to the frame of the machine.
  • the needle could equally well be mounted in a known so-called pendulum-type arrangement.
  • An arm 3a of the cradle 3 is connected, by a rod 5, to a control member 6 which is mounted so as to be slidable on the frame 7 of the machine and which can be displaced in reciprocating movement.
  • the movements of the control member 6 in one direction or the other are produced by two electromagnets 8 and 9 respectively.
  • the amplitude of these displacements is limited by one or other of a series of rods 10, 11, 12 fast with the plunger cores of three electromagnets 13, 14 and 15 respectively.
  • These rods are each adapted to occupy either a withdrawn position or a working position in which they each penetrate into one of a series of three holes 16, 17 and 18 formed in the control member 6.
  • These holes are of difierent diameters and each determines two distinct positions of the member 6 when the corresponding rod is in the working position, depend ing on the direction in which the member 6 has been displaced in order to bring the edge of the hole to abut against the rod.
  • These holes thus determine six different positions of the member 6, to which are added the two extreme left-hand and right-hand positions which it can occupy when all the rods are in the withdrawn position.
  • the diiferent electro-magnets 8 and 9, and 13 to 15 are energised by a current source 19, connected by a wire 20, and a frictional contact 21 to a ring 22 surrounding a plate 23 made of insulating material. Small con tact rods 24 are housed in this plate 23. A perforated disc 25 rests on the ring 22. Finally, five electrical contacts 26a to 26e are connected, by wires 27a to 27 respectively, to the electromagnets 8 and 9 and 13 to 15.
  • the machine will comprise a plurality of discs 25 havingpdifferent perforations, which will be readily intermodify the and could be replaced by-a dilferent mechanism, whereas the electromagnets 12 to 15 are selectors for the position which the control member 6 is to occupy.
  • control device 29 (FIGURE 4) instead of being applied to the needle.
  • a digital programme controller furnishing electric signals, a series of electromagnets to which the said signals are transmitted, a seriesof mobile abutments controlled by the said electromagnets and each adapted to occupy two positions, a withdrawn position and a working position, a slidable control member which is connected mechanically to the said element which is to be controlled and finally a driving member operatively connected to said control member displacing it in the one or the other direction
  • the said control member comprising arresting surfaces distributed as a number of pairs, the two surfaces of each pair facing each other, each of the aforesaid mobile abutments cooperating with one pair of the said arresting surfaces, more precisely with one or with the other surface of the said pair, depending on the direction in which the said control member is moving at the instant when the said abutment comes into its working position, whereby each mobile abutment determines
  • a control device for controlling the position of a machine element, especially for controlling the position of the needle bar or of the work feed device of a sewing machine, a digital programme controller furnishing electric signals, a series of electromagnets to which the said signals are transmit-ted, a series of mobile abutments controlled by the said electromagnets and each adapted to occupy two positions, a withdrawn position and a working position, a slidable control member which is connected mechanically to the said element which is to be controlled and finally a driving member operatively connected to said control member for displacing it in the one or the other'direction, the said control member being formed with perforations into each of which one of the said mobile abutments is adapted to penetrate, and whose diametrically opposite lateral walls constitute arresting surfaces for said abutments, whereby each mobile abutment determines two stopping positions of the control member depending on whether the latter has come into contact with the abutment when being displaced in one direction or the other.
  • a control device for controlling the position of a machine element, especially for controlling the posi- .said control member for moving it respectively in one direction or the other, the said control member comprising arresting surfaces distributed as a number of pairs, the two surfaces of each pair facing each other, .each of the aforesaid mobile abutments cooperating with one pair of the said arresting surfaces, more precisely with one or with the other surface of the said pair, depending on the direction in which the said control memher is moving at the instant when the said abutment comes into its working position, whereby each mobile abutment determines two stopping positions of the control member.
  • a control device for controlling the position of a machine element, especially for controlling the position of the needle bar or of the work feed device of a sewing machine, a rotatable perforated disc constituting a digital programme controller, electrical contacts controlled by said disc, a series of electromagnets operated by said contacts, a series of mobile abutments controlled by said electromagnets and each adapted to occupy two positions, a withdrawn position and a working position, a slidable control member which is connected mechanically to the said element which is to be controlled and finally a driving member operatively connected to said control member for displacing it in the one or the other direction, the said control member comprising arresting surfaces distributed as a number of pairs, the two surfaces of each pair facing each other, each of the aforesaid mobile abutments cooperating with one pair of the said arresting surfaces, more precisely with one or with the other surface of the said pair, depending on the direction in which the said control member is moving at the instant when the said abutment comes into its working
