Definitions

  • This invention relates to the manufacture of artificial silk but more specifically has for its object to devise an improved spray shield for use on spinning machines.
  • rollers which may be driven or rotated solely by the passage of the filaments thereover are used.
  • the purpose of these rollers is to act either as guides or as stretching means for the freshly spun artificial silk filaments.
  • the rollers are rather smaller in circumference'and have a high angular velocity which causes the surplus acid of the spin bath carried by the filaments to be thrown 01f in a spray.
  • Baffle plates or spray shields have been suggested and used for the protection of the spinning machine operator and to facilitate the recovery of thespin bath.
  • Ordinary spray shields which are made in the form of solid plates, become incrusted with salt crystals when they are continuously subjected to the spraying from the spin bath liquids. This incrustation of the spray shield may be entirely eliminated if the said shield is continuously and over its entire surface sprayed by a liquid.
  • the liquid thrown off from the rotating rollers splashes against the slotted shield and a portion of the liquid penetrates through the openings to the opposite side of the shield and a spraying of the said shield takes place on both sides without allowing the spray to be thrown therefrom.
  • the spray shield is also formed in such a manner as to lead, back a portion of the sprayed solution to the roller in order that the said roller may revive a constant spray and prevent crystallization thereon.
  • Another object of the present invention is to devise a spray-shield which will lead back a portion of the solution spray to the roller and thus prevent crystallization taking place thereon.
  • the invention consists in the novel features of construction and in the combination,
  • Fig. l is a side elevation of the spray shield and in dotted lines is indicated the relative position of the roller which it is intended to shield,
  • Fig. 2 is a front elevation of the novel spray shield
  • Fig. 3 is a plan view of the perforated blank 10- before it has been bent to form the spray shield comprising the invention.
  • the projections 5 and 6 act to return a portion of the spray to the roller 2 and thus prevarious shapes other than the parallel slots illus- 4o trated in the drawing.
  • the essential feature of the openings is to make them narrow enough that the spray is prevented from being thrown through while allowing a constant seepage to take place as the solution flows down the inner side of the shield 3. By sloping the slots 8, as illustrated, the seepage of liquid to the outside is facilitated.
  • a rotatable element from which liquid may spray and a shield to intercept said spray said shield comprising an upstanding portion having openings formed therein to allow a portion of the intercepted liquid to pass to the opposite side of said shield, and an upper portion bent at an acute angle and extending downwardly to and overhanging said rotatable element.
  • a rotatable element from which liquid may spray and a shield to intercept said spray said shield comprising an upstanding portion having openings formed therein to allow a portion of the intercepted liquid to pass to the opposite side of said shield and an upper portion bent at an acute angle, said bent portion comprising tapered projections extending downwardly and overhanging said rotatable element.
  • a rotatable element from which liquid may spray and a shield to intercept said spray said shield comprising an upstanding portion and an upper portion comprising tapered projections having openings formed therein to allow a portion of the intercepted liquid to pass to the opposite side of said shield, said projections being bent at an acute angle and extending downwardly to and overhanging said rotatable element.
  • a rotatable element from which liquid may spray and a shield to intercept said spray said shield comprising an upstanding portion having parallel slots formed therein which are at an angle to a horizontal plane to allow a portion of the intercepted liquid to pass to the opposite side of said shield, and an upper portion bent at an acute angle, said bent portion comprising tapered projections extending downwardly and overhanging said rotatable element, said projections having slots formed therein to allow a portion of the intercepted liquid to pass to the opposite side of said projections.
  • a rotatable element from which liquid may spray and a shield to intercept said spray said shield comprising an upstanding portion having parallel slots, which are at an angle to a horizontal plane, formed therein to allow a portion of the intercepted liquid to pass to the opposite side of said upstanding portion, and an upper portion bent at an acute angle, said bent portion comprising tapered projections extending downwardly to and overhanging said rotatable element, said projections having slots formed therein to allow a portion of the intercepted liquid to pass to the opposite side of the said projections and a bracket member formed integral with said upstanding portion.
  • a rotatable element from which liquid may spray and a shield to intercept said spray said shield comprising an upstanding portion having openings formed therein to allow a portion of the intercepted liquid to pass to the opposite side of said upstanding portion and an upper portion bent at an acute angle thereto, said upper portion consisting of tapered projections extending on either side of said rotatable element and ending directly above the axis of said rotatable element.
  • a rotatable element from which liquid may spray and a shield to intercept said spray said shield comprising a main body portion, and tapered portions projecting beyond said body portion and extending downwardly to said rotatable element and on either side thereof, said tapered portions ending directly above the axis of said rotatable element.
  • a spray shield comprising an upstanding main body portion having slots extending substantially in horizontal direction, and an upper portion inclined downwardly from said main body portion and having slots extending substantially longitudinally of the upper inclined portion.
  • a spray shield comprising an upstanding main body portion having parallel slots which are at an angle to a horizontal plane, an upper portion inclined downwardly from the upper end of said main body portion and having slots extending substantially longitudinally of the upper inclined portion, and a bracket member formed integral with said main body portion.
