Definitions

  • This. invention relates to. stop motion devices for use on textile machines tor. autom cal y ppi g machine when a strand of textile material being operated on by the machine breaks or acquires anexcessive amount of slack.
  • the invention is especially adapted for use on roving machines and machines of a similar nature in which a strand of textile material is twisted and drafted simultaneously.
  • My invention isconcernecl with stop motion devices of the type in which a drop wire is provided for each strand arid each dropwire controls an electric switch to close a circuit to stop the machine when any drop Wire responds to a: break in a strand or to an excessive amount of slack in a strand.
  • One feature of the present invention is the provision of a mounting bar extending throughout the length of the machine for supporting individual switch structures which provide pivotal mounting for the drop wires.
  • the mounting bar embodies twoelectric conductors arranged in parallel relation and supported on the bar in such manner that the necessary electric connections are completed .to each switch structure bythe mounting of the switch in its, normal position on the mounting bar.
  • Each switch structure is provided with two contact pacts extending out of the switch casing inproper position to engage the two conductors carried by the mounting bar.
  • a further feature of the invention comprises an improved switch structure having a pivoted switch element which provides a pivoted support for a drop wire.
  • Figure 1 is a diagrammatic view showing a fragmentary part of a roving machine in front elevation
  • Figure 2 is a sectional View of Figure 1 taken along the line 2--2 and showing one textile strand. in operative relation with one drop wire;
  • Figure 3 is an enlarged plan view of one of the. switch structures showing the top portion of the switch casing removed;
  • Figure 4 is a sectional view of Figure 3 taken along the line 44, but showing the top portion of the switch casing in its normal position;- and Figure 5 is a plan view of a ringelement providing a bearing support for the rotary element of'the switch.
  • power driven draft rolls of the roving machine are indicated at 1-, and .the .cooperating top rolls, which are usually covered with. cork or leather; are shown at 2..

  • the special mount-ing strip is formed of a strip 11 of suitable insulating'mater-ia-l; such as wood', andis fastened by any suitable means to the front face offlange 4a.
  • a pair of electric conductors 12 and 16 are carried bythe strip 11 in suchposition that proper connect-ions to the different switches are completedsimply by mounting the switch casing on the mounting strip.
  • One suit-able arrangement is to provide conductors 12 and 13' in the form of fiat strips whichare mounted within parallel grooves formed on the front face of the insulating strip 11, the conductors 12 and 13 extending slightly above the outer face of strip 11 to facilitate making electric connections with the projecting parts of the electricswitches.
  • conductors 12 and 1% could be mounted on the narrow edges of; strip 11-.
  • Theswitch casing is formed of a base section 10a and a top or cover section 1%, both being formed of molded insulating material.
  • the top section 10b hasbeen removed from the unit shown in Figure 3 but shown in proper position in Figure 4.

  • the strap 14 is located so that the ears 14a and 1412 make contact with conductor 12- when the switch housing is secured to mounting strip 1 1.
  • the shaft 9 for supporting the drop wire 8 is journalled near its outer end inthe top wall of cover portion 10b of the casing andisprovided with a section 9a of enlarged diameter loca-ted partly within the top section and extending into the bottom section of the casing.
  • the enlarged section 9a of shaft 9' is journalled within the bottom por tion 10aof the casing by means of a metallic ring 15 which is held in proper position within the bottom section of the-casing'by' any suitable means, such as lugs 16a, 1-61) and extending'u-p from the bottom wall of the casing.
  • the ring- 1-15- is provided with a tail piece 15a extending outwardly from the ring and having its end portion clamped between thetop and bottom section of the casing.
  • the enlarged portion 9a of shaft 9 is provided with a transverse groove 9b formed substantially through onehalf of the enlarged portion and in a position to receive the central portion of metal strap 14.
  • the strap 14 is notched at its central section so that the bottom edge 140 of the notch is parallel with the bottom of the notch 9b in the shaft section 9a when the drop wire 8 is in a vertical position.
  • the stop circuit may be of known form and is represented diagrammatically in Figure 1 as including a source of current 17 and an electromagnet 18 which operates any suitable means to effect stopping of the machine.
