Definitions

  • the present invention relates to a double belt drawing mechanism for spinning machines and more particularly to a cage apparatus for the upper belt of the drawing mechanism which simultaneously guides both the upper and the lower belts.
  • One of the objects of the present invention is to overcome the above disadvantage by providing a belt cage which is tiltable together with theupp'er belt and its guide member.
  • An additional object of the present invention is to provide a cage member of the above type which will also serve to insure the proper position of the upper and lower belts with respect to each other.
  • a further object of the present invention is to provide a means for limiting the upward movement of the cage member together with the upper belt and guide member therefor in a direction away from the lower belt member.
  • Yet another object of the present invention is to provide a cage member capable of accomplishing all of the above objects and at the same time being a relatively simple and inexpensive construction and being reliable in operation.
  • FIG. 1 is a side elevational view, partly in section, of a drawing mechanism constructed in accordance with the present invention and showing the cage member of the present invention in the operative position thereof;
  • FIG. 2 is an end view taken of the structure of FIG. 1, as viewed from the left hand side thereof, and showing part of the cage construction in section;
  • FIG. 3 is a side elevational view, partly in section, of a structure similar to that of 'FIG. 1, but slightly modified, showing the cage member of the present invent-ion in its inoperative position and also illustrating the supply and delivery rollers for the drawing mechanism.
  • the driving roller .1 which may be rotated by any suitable means and which has the belt 2 of the double belt drawing mechanism mounted thereon.
  • This belt 2 passes over a guide member 3, which is fixedly mounted on the spinning machine by any suitable means, not shown, this guide member 3 being elongated and parallel to the axis of rotation of roller 1.
  • the guide member 3 has the projection 11 fixedly mounted thereon.
  • This projection 11 may be fixedly mounted on the guide member 3 by any suitable means such as screws, welding, or the like, or it may be formed as an integral part of the guide member 3.
  • the driven roller 5 Located over the driving roller 1 is the driven roller 5 which may be mounted on the shaft 9 for free rotation thereon or which may rotate with the shaft 9, the latter then being mounted for free rotation.
  • the roller 5 supports the upper belt 4 of the double belt drawing mechanism, this belt 4 contacting the belt 2 so as to be driven by the latter upon rotation of driving roller '1, the driven roller 5 rotating along with the belt 4.
  • a tensioning idle roller rests with its weight on the lower portion of belt 2 so as to maintain the same taut over the driving roller 1 and guide member 3.
  • a cage means 8 which is essentially a channel-shaped member having an open bottom.
  • the side walls 7 of the cage means 8 have lower curved portions adjacent the right hand end portion of the cage means 8, as viewed in FIG. 1, and these lower edge portions rest on the shaft 9 on opposite sides of the roller 5, respectively, so as to support the cage means '8 for turning movement about the axis of rotation of the upper roller 5.
  • Pivotally mounted on each of the side walls 7 of the cage means 8 is a hook member 10 which engages the projection 11 of guide member '3, when the cage means is in its operative position, so as to maintain the cage means 8 in proper position in the drawing mechanism during the operation thereof.
  • the guide members 6 which are positioned over the guide member 3 and respectively fixed to one of the side walls 7 of the cage means 8, as shown in FIG. 2.
  • the guide members 6 support the belt 4 for movement with the belt 2 and roller 5. It will be noted that the hook members 10 maintain the cage means 8 in the desired location during the operation of the drawing mechanism and prevent any upward turning of the belt 4 and cage means 8 about the axis of rotation of roller 5 during operation of the drawing mechanism.
  • the sides 7 of the cage means 8 are provided with lower intermediate extensions 17 which extend below the upper belt'4 and a portion of the lower belt 2 so that the inner sides of these extensions prevent lateral displacement of the belts 2 and 4.
  • FIG. 3 of the drawings where the supply rollers 12 and 13 and the delivery rollers 14 and 15 are diagrammatically illustrated in their inoperative position with respect to the structure shown in FIG. 1.
  • the sides 7 thereof may be provided with upper extensions 16 which rest against roller 12, as shown in FIG. 3, when the cage means 8 is in its inoperative position.
  • a double belt drawingmechanism comprising, in combination, a lower driving roller; a lower fixedly mounted elongated, first guide member spaced from said lower driving roller and being substantially parallel to the axis of rotation thereof; a lower belt mounted on said lower roller to be rotated thereby and passing over said first guide.
  • an upper driven roller mounted for rotation about an axis parallel to the axis of rotation of said lower roller and, being located adjacent thereto; an upper belt mounted, on said upper roller and contacting said lower belt so as to be driven by the latter to rotate said driven roller; a shaft member supporting said upper roller for rotation thereon; a channel-shaped cage member having an open bottom and having side walls provided with lower edge portions adjacent one end of said cage member and resting on said shaft member on opposite sides of said upper roller, respectively, to support said cage member for pivotal movement about said axis of rotation of said upper roller; at least one second guide member located between said side walls of said cage member and being fixedly mounted over said first guide member on said side walls, said second guide member supporting said upper belt for rota tion together with said upper roller; a projection fixedly mounted on said first guide member; and a hook pivotally mounted on said cage member for releasable engagement with said projection, whereby, when said hook is released from said projection, said cage member together with said second guide member and upper belt may be pivoted about
