Definitions

  • One of the objects of the present invention is to overcome these difficulties by providing a means for covering such parts of the apparatus so that they do not become dirty and so that a roving cannot become caught or torn thereon.
  • a further object of the present invention is to provide a cover of the above type which is easy to mount and dismount on the machine.
  • Another object of the present invention is to provide a cover which does not require the conventional drawing mechanism structure to be altered to accommodate the cover. 7
  • An additional object of the present invention is to provide a cover which will automatically remain in 'engage ment with the drawing mechanism at all times.
  • the present invention mainly consists of a drawing mechanism which includes a stationary support having a front side and rear side and an elongated arm having a rear end pivotally connected to the support for movement about a horizontal axis and being adapted to carry the toprolls of the drawing mechanism.
  • Acover member has a pair of opposite side walls respectively facing opposite sides of the support i and arm and a rear wall interconnecting the side walls and facing the rear side of the support and the arm, this cover member being mounted on the support for free movement in a forward direction toward the latter and said arm so as to remain in engagement with the support and arm in all positions of the latter.
  • Fig. 6 is a side elevational view of a different embodiment of a cover constructed in accordance with the present invention.
  • Fig. 7 is a fragmentary, partly diagrammatic, perspective view of the structure of the invention illustrated in association with a roving being guided to the drawing plane.
  • Fig. 1 shows the stationary support 12 which is clamped to the rear stationary bar of the drawing mechanism by the bolt 13, this rear bar not being shown in Figs. 1 and 2 and being carried by the stationary base of the apparatus on which the bottom rolls are mounted.
  • a pin 14 is fixed to and extends through the support 12 with opposite end portions of the pin 14 respectively extending beyond the opposite sides of the support 12.
  • the arm 10, which carries the top rolls of the drawing mechanism, is pivotally mounted at its rear end on the pin 14 for movement about the horizontal axis of pin 14 between the operative position shown in Fig. 1 and the inoperative position shown in Fig. 2. In the operative position of Fig. 1, the arm 10 extends downwardly and forwardly in a direction parallel to the drawing plane.
  • the arm 10 is channel shaped and is provided with outwardly pressed side portions which are respectively located at the opposite sides of support 12 and respectively formed with openings through and beyond which the end portions of the pivot pin 14 respectively extend.
  • the arm 10 carries a catch member 11 which cooperates in a known way with the portion 19 of the support 12 to releasably hold the arm 10 in the operative position of Fig. l. v
  • FIGs. 1 and 2 show the cover member 15 of the invention mounted on the apparatus, and the details of this cover member are further illustrated in Figs. 3-5 of the drawings.
  • This cover member 15 includes a rear wall 155 which is curved forwardly at the part 156 thereof.
  • a pair of parallel substantially triangular side walls 153' extend forwardly from the opposite rounded side edges 158 of the rear wall 155, and the cover member is formed with a pair of elongated aligned cutouts taking the form of slots 151 respectively passing through the side walls 153.
  • the top edge 159 of the rear wall 155 is curved, as is best shown in Figs. 4 and 5, and the opposite side walls 153 are each formed with a cutaway portion 150 (Fig. 3) located adjacent to the top edge 159 of the rear wall 155.
  • the slots 151 extend forwardly and downwardly so that the cover member 15 rests at the upper edges of the slots 151 on the pin 14 and is urged forwardly by its own weight.
  • the top edge 159 engages the arm 10
  • the bottom portion of the cover member 15 engages the support 12 at the part 160 thereof.
  • Fig. 2 upon release of the Fig. 1 is a fragmentary side view of the rear portion of r catch means 11, 19 and upward turning movement of the arm 10 to the inoperative position shown in Fig. 2, the
  • the cover member 15 is preferably made of a resilient sheet material, such as sheet metal, so that its opposite sides 153 may be yieldably moved away from each other to pass over the opposite end portions of pin 14 when the cover member is being mounted on and removed from the machine.
  • a cover having the construction of cover member 18 of Fig. .6 whichis identical-in all respects with the cover member 15 except .that instead of slots 15] the cover member 18 is provided with cutouts in 'the forrn-of notches .181 whichmay bemoved onto the. opposite ends of pin .14 Without moving the opposite side walls of the cover member away from each other.
  • the cover member 13 may also he made of a resilient sheet material,- if' desired.
  • the cover member 15 is shown in association with a roving 31 in Fig. 7 which also shows the rear bar ".011 which the support 1.2 is .clampedby the .bolt -13.
  • the roving31 is takeufrom a spool 130 locatedtothc "(car and to one side .of the support 1,2, arm it ⁇ , and cover member 15.
  • An eye 32 is mounted on stationary part of the apparatus'to guide the roving :51 to the drawing plane. When the roving is first threaded through "the apparatus and before the latter is started -.up,.the,roving 3]. usually rests against the top part of the arm .10.
  • the loose roving is pullcdgand moves rearwardly along the arm 10 and slips downwardly about the curved rear portion thereof and over the top curved edge 159 of the cover 153 to the position shown inFig. 7 wherethe roving passes about one of the rounded side edgesv 158 of rear wall 155 of the cover to the eye 32 and through the latter to the drawing plane.
  • the top edge 159 prevents catching of theroving due to the curved shape of this top edge, andthe rounded side edge 158 of the rear wall 155 guides-the roving 31 with a minimum 'of friction.
  • the roving 31 cannot tear or become caught on projecting parts of the apparatus and more over is guided with a minimum of friction to'the drawing plane.
  • the roving moves up and down along the rear wall 155 through a small portion of the length thereof.
  • the invention is of particular significance when used with an arrangement similar to that shown in Fig. 7 where t. e spool 30 is located to'the rear and to one side of the support 12 and arm 110, because it is with just such an arrangement of parts that catching and tearingof the roving would most frequently occur if the apparatus were not provided with a cover 15.
