Definitions

  • This invention relates to apparatus for the manufacture of artificialsilk or other artificial threads or filaments and more especially to apparatus for the manufacture of artificial threads or filaments by the dry or evaporative method.
  • the object of the invention is to obviate or to overcome in a large measure these difiiculties.
  • a valve controlling the supply of the spinning solution to the jet or nozzle (referred to in the claims as the extrusion device), which valve is adapted to close or be closed automatically on the removal of the jet or nozzle, and to be automatically and mechanically opened by the it preferable however to construct or arrange the valve so as in its closed position to allow a certain predetermined quantity of the spinning solution to escape, and especially to allow such a quantity to escape as ordinarily passes through the jet or nozzle when the jet or nozzle'is spinning under the given pressure, or such a quantity as will ensure the pressure in the supply of the spinning solution remaining substantially constant.
  • the valve and/ or its seat may be grooved, slotted or otherwise suitably formed to give the desired passage of spinning solution when the valve is in the closed position.
  • the valve is situated immediately behind the jet or nozzle.
  • the spinning jet or nozzle When the spinning jet or nozzle is fitted to the pipe or other member, it raises and supports the valve in the open position by means of the valve stem.
  • the valve stem is constructed toslide in the bore or-passage referred to and act as a guide for the valve and is suitably formed or adapted to permit passage of the spinning solution.
  • the lower end or" the valve stem is preferably formed as a disc, ring or flange which has a sliding lit in the bore or passage referred to and which is formed with or presents'one or more holes to permit passage of the spinning solution.
  • the disc, ring or flange is referred to as the guiding member.
  • the valve on the removal of the spinning jet or nozzle the valve will fall on to its seat and thereby, cut oil or restrict the fiow of spinning solution.
  • a spring is preferably fitted between the top of the valve and an abutment above the same; forinstance, when a filter-containing chamber is employed in the supply pipe orconduit above the valve, the filter may conveniently serve as such abutment.
  • the valve may be constructed to cut off the supply of spinning solution entirely when the jet or nozzle is removed; preferably, however, grooves or passages are formed in the face of the valve and/or on the face of the seat to enable a desired amount of spinning solution to escape when the valve is closed.
  • such grooves or passages may permit the escape of an amount such as to maintain substantially con-' stant pressure in the supply of the spinning solution, or to allow such quantities of spinning solution to escape as are normally passed'through the jet'or nozzle in spinning. ,1
  • valve is fitted in the lower-part of a filter-containing chamber which terminates the supply pipe to which the jet or nozzle is fitted.
  • Figure 1 is a sectional view, with the valve in elevation, showing the nozzle or jet attached in position for spinning and the valve in the open 1 position.
  • Figure 2 is a similar view but with the jet or nozzle removed and the valve in the closed position.
  • v 65 Figure 3 is a horizontal section on the line A-B Figure 2.
  • Figure 4 is a horizontal section on line 0-D Figure 2.
  • 1 indicates the 1m member forming the body of the cylindrical filter-containing chamber 2 which terminates the supply pipe to the spinning jet or nozzle and to which the jet or nozzle is attached, the member 1, shown broken away, terminating the supply pipe.
  • the lower part of the body 1 is formed with a bore of relatively smaller diameter.
  • the spinning jet or nozzle 4 is attached (as shown in Figure 1) by screwing it on to the threaded end 5 of the member 1, the jet or nozzle being fitted with a packing ring 411.
  • valve 6 is a conical valve carried by'the valve stem 7 working in the bore 3, and adapted to close on to a seat 8 formed at the top of the bore 3.
  • the valve stem is guided in the bore 3 by a grooved upper collar or piston 9 and a lower ring or disc 10 the latter having holes 17, the collar 9 and ring or disc 10 both having a sliding lit in the bore 3.
  • one or more filter cloths may be interposed atany point between the jet or nozzle 4 and the ring or disc 10.
  • Grooves 18 are formed in the conical face of the valve 6, and a recessed chamber 3a is formed in the bore 3 beneath the seat 8, and the valve stem '7 is formed or provided at its lower part adjacent to the ring or disc 10, with a radially webbed or cruciform portion formed with slots 16.
  • the spinning solution passes laterally out through the filter walls 1 1 of the filter 12 into the chamber 2 which is filled with the solution under pressure. From the charm ber 2 it passes between the valve 6 and seat 8 thence through the grooves 15 in the piston or collar '9, thence down the bore 3 and through the slots 16 in the radial webs'm of the webbed portionof the valve stem '7, and through the holes 17 in the ring or disc 10 to the spinning jet or nozzle 4.
  • the valve 6 closes on to its seat 8.
  • the spinning solution now passes through the grooves 18 in the face of the conical valve 6, the grooves being so dimensioned that only a desired quantity of spinning solution will escape, for example, such as will maintain the pressure in-the supply substantially constant or such as would ordinarily be extruded in spinning.
  • the spinning solution passes from the apparatus via the recessed chamber 3a and the grooves 15 in thepiston or collar 9, down the bore 3, through the slots 16 ofthe radial webs 7a of the valve stem '7 and escapes through the holes in the ring or disc 10.
  • Apparatus as claimed in claim 1 having means for permitting a predetermined quantity of spinning solution to escape when the valve is in its closed position.
  • Apparatus as claimed in claim 1 having a spring for bringing the valve to its closed position when the extrusion device is removed.
  • Apparatus as claimed in claim 1 having a pipe or member to which the extrusion device is attached and in which the valve is provided with a stem that slides in a bore of the pipe or other member and acts as a guide for the valve while providing a passage for the spinning solution.
  • Apparatus as claimed in claim 1 having a pipe or member to which the extrusion device is attached and wherein the valve is provided with a stem that slides in a bore of the member to which the extrusion device is fixed and acts as a guide for the valve while providing a passage for the spinning solution, the said stem being provided at its lower end with a guiding member sliding in said bore and having at least one hole for the passage of the spinning solution.
  • Apparatus as claimed in claim 1 and having means for permitting such quantity of spinning J solution to escape when the valve is in the closed position that the pressure in the supply of spinning solution remains substantially equal to that obtaining during the normal spinning through the extrusion device.
