Definitions

  • bracket which turnably carries a top rolls carrying arm for movement to and from an operating machine.
  • This bracket is conventionally fixed to a bar carried by the frame.
  • the fixing of the bracket to the bar is usually brought about by providing the bracket with a pair of springy free end portions passing about the bar and drawn together by a screw or the like into clamping engagement with the bar.
  • One of the objects of the present invention is to overcome the above drawbacks by providing a means on the bracket capable of clamping the bracket to the bar with an extremely large force after application of a small fraction of this large force to this means.
  • Another object of the present invention is to provide a bracket of the above type with a clamping means which fixes the bracket to the bar in a manner far superior to anything which has hitherto been possible.
  • a further object of the present invention is to provide a bracket and a clamping means of the above type both of which are of an exceedingly simple and compact construction.
  • the present invention mainly consists of a textile drawing mechanism which includes a support means carrying a bar.
  • a bracket is formed with an opening through which the bar extends, and this bracket is adapted to carry a top rolls carrying arm of the drawing mechanism.
  • This bracket has a portion spaced from the bar and provided with a surface directed toward the bar.
  • a wedge member is located in the space between the bracket portion and bar and engages the latter and the surface of the bracket portion. A means engages this wedge member for wedging the same into this space against the bar and this surface of the bracket portion so as to fix the bracket to the bar.
  • Fig. 1 is a fragmentary, diagrammatic side elevational view of a textile drawing mechanism including the structure of the invention
  • Fig. 2 is a fragmentary sectional view showing the details of the invention on an enlarged scale as compared to Fig. 1, Fig. 2 being taken along line 2-2 of Fig. 3 in the direction of the arrows; and
  • Fig. 3 is a sectional view taken along line 33 of Fig. 2 in the direction of the arrows.
  • the textile drawing mechanism illustrated therein includes a frame A to which a bracket B is fixed.
  • a top rolls carrier C is turnably carried by the bracket B for movement from the operating position shown in Fig. 1 in a clockwise direction upwardly to an inoperative position.
  • Blocks 243 which turnably carry the bottom rolls 41, respectively, are shiftable along the frame A in a known way to adjust the position of the bottom rolls.
  • the top rolls carrier C has arms 23 connected thereto, and these arms 23 turnably carry the top rolls 22, respectively, which engage the bottom rolls 41, respectively, these top rolls also being adjustable in a known way so as to properly engage the bottom rolls, respecttively.
  • Fig. 1 diagrammatically shows clearer rolls 39 respectively in engagement with the top rolls 22.
  • a releasable lock member 14 and a rivet 35 are also visible in Fig. 1 and are referred to in greater detail below.
  • Figs. 2 and 3 show the bracket B and the parts of the drawing mechanism associated therewith.
  • This bracket B is, made out of a springy sheet metal bent in a press or the like to the shape shown in Figs. 2 and 3.
  • the bracket B includes a pair of side walls 24 and 25 which are spaced from each other and interconnected by a rear wall 26 of the bracket.
  • the bracket is formed between the side walls 24 and 25 with a lower cutout 27 and an upper cutout 28, as shown in Figs. 2 and 3, so that the side walls 24 and 25 are interconnected only by the rear wall 26, and in this way the side walls 24 and 25 are resiliently movable toward and away from each other.
  • the rear wall 26 is formed with an opening 29 for a purpose described below.
  • Each of the side walls 24 and 25 is provided with an inwardly pressed portion having a surface directed toward the bar 10.

  • the side wall 24 is provided with an inwardly struck portion 32 bent at 38 inwardly from the side wall 24, and the side wall 25 is provided with an inwardly struck portion 33 bent at 31 inwardly from the side wall 25.
  • These inwardly struck portions 32 and 33 are cut from material of the side walls 24 and 25, respectively, and are respectively provided with surfaces directed toward and spaced from the bar 10, these surfaces being located at the free edges of the inwardly struck portions 32 and 33, respectively.
  • the portions 32 and 33 make the same acute angle with the remainder of the side walls 24 and 25, respectively, and the free edges of the portions 32 and 33 are parallel to each other and located opposite each other.
  • the side walls 24 and 25 are re spectively formed with aligned openings of substantially the same diameter as bar 10 and through which the bar it extends.
  • a pair of wedge members 16 and 17 are located within the bracket B between the side walls 24 and 25 thereof, and, as is evident from 'Fig. 3 where the front end face of wedge member 17 is visible, these wedge members have .a width substantially equal to the distance between side walls 24 and 25.

  • the wedge member 17 is formed in its top face directed toward the inwardly struck portions 32 and 33 with a channel having opposed side faces of the same inclination as and respectively engaging the outer side faces of the inwardly truck portions 32 and 33, so that the wedge member 17 is provided along its length with an upper rib 172 located between inwardly struck portion 32 and the remainder of side wall 24 and with an upper rib 173 located between inwardly struck portion 33 and side wall 25.
  • the wedge member 16 is formed in its top face with a channel having opposed side faces of the same inclination as and engaging the outer side surfaces of the inwardly struck portions 32 and 33, so that wedge member 16 has along one of its upper side edges a rib 162 located between inwardly struck portion 32 and the remainder of side wall 2 1, as shown in Fig. 2, and along its upper side edge opposite rib 162 with a second rib not visible in the drawings located between the inwardly struck portion 33 and side wall 25 in alignment with the rib 173 of the wedge member 17.
  • the inwardly struck portions 32 and 33 are substantially longer than the total length of the wedge members 16 and 17 which engage these inwardly struck portions.
  • the wedge member 17 is formed with a bore passing therethrough and the wedge member 16 is formed with a bore aligned with the bore of wedge member 17 and being coaxial therewith.
  • a screw 18 extends freely through the bore of wedge member 17 into threaded engagement with the bore of wedge member 16, and the head of screw 18 bears against the right end face of wedge member 17, as shown in Fig. 2.
  • the head of screw 18 is in alignment with opening 29 and is formed at its right end face, as viewed in Fig. 2, with a non-circular recess adapted to receive a key wrench passing through opening 29 into engagement with the screw member 18 for turning the latter.
