Definitions

  • ABSTRACT OF THE DISCLOSURE An upper roller carrying arm for the drawing frame of textile dressing and spinning machines in which the arm can be moved from a working position to a rest position parallel to the working position and vice versa and the arm can only be rotated about its supporting member when the rest position has been attained.
  • This invention relates to an arm for supporting the upper rollers of the drawing frame of textile dressing and spinning machines, and more particularly comprises a casing preferably of inverted-U cross-sectional configuration by which the upper rollers are carried, guided and urged by resilient means for pressing with a greater or lesser pressure upon the lower rollers of the machine.
  • the upper rollers are coated with a somewhat resilient material and, in operation, are pressed by their respective springs against the lower rollers, thereby resulting in a certain compression of their surfaces.
  • upper roller carrying arm comprises means for moving the arm from a working position to a rest position parallel to the working position, and vice-versa, and such means permitting the rotation of the arm about its own supporting member only when the rest position has been reached.
  • the above outlined means bring the arm from its active position in which the upper rollers are pressed with the usual required pressure against the lower rollers to the rest position at a higher level and in which the upper rollers are constantly maintained in contact with the lower rollers but under a pressure which is substantially .due to the weight of the arm per se and vice-versa. By such action, the acquired twist and draft are maintained unchanged and work can be resumed without any difficulties.
  • FIGURE 1 is a diagrammatic view illustrating in a simplified manner the several positions the arm can assume according to the invention.
  • FIGURE 2 is a side view pantly in elevation and partly cross section of the arm in the usual operative position.
  • FIGURE 3 is a view similar to FIGURE 2 showing the arm in its rest or inoperative position.
  • FIGURE 4 is a view similar to- FIGURE 2 showing that once the inoperative position has been reached, the arm must be rotated by lifting all of its rollers, thus moving such rollers completely out of the way of the lower rollers.
  • FIGURE 5 is a view similar to FIGURE 2, and illustrates the details of the abutment.
  • FIGURE 6 is a view taken along the line VIVI of FIGURE 5.
  • FIGURE 7 is a view similar to FIGURE 2 of a constructional modification of the arm.
  • FIGURE 8 is a fragmentary view on an enlarged scale of the supporting member mounted on the fixed horizontal shaft
  • FIGURE 9 is a cross-sectional view taken along the
  • the upper-roller carrying arm according to the present invention comprises a casing 1 which is of in'verted'U configuration with a horizontal web 2 arranged at the highest level and parallel vertical flanges 3.
  • the casing is provided with a pivot 4 defined by a roller 4' (FIG. 6) housed with vertical slots 5 formed in a supporting member 6 keyed onto a fixed horizontal shaft 7.
  • the supporting member as well as the components 4-5 will be described in more detail hereinafter.
  • the arm or casing 1 has, in the embodiment shown, an upper feed roller 9, an intermediate roller 10 and a final draft roller 11 coupled to lower rollers 8 which are rotatable at fixed locations.
  • Each of the rollers 9, 10 and 11 is carried by a support 12 pivoted to the flanges 3 of the casing 1 at 13 and the supports 12 carry at 12' the rollers 9, 10 and 11.
  • a spring 14 is biased between each support 12 and lower face 16 of the web 2 and the springs press the rollers 9, and 11 against the lower rollers 8, with the maximum pressure being exerted in the operative position indicated by dash line A-A' in FIG. 1.
  • the supporting member 6 (FIG. 6) is provided with an idle pivot 17 which carries a roller 17 in central position. Between the pivot 4 and the pivot 17 is inserted a wedgeshaped end portion 18 of a rod 19, and the portion 18 has an upper sloping surface merging with a fiat horizontal surface 21 on which the pivot 17 rests in the active position disclosed in (FIG. 1.
  • the sloping surface 20 of the end of the rod 19 preferably arched, i.e., a curvilinear surface.
  • the manner in which the arm is guided during its movement from one position to the other is immaterial so that the surface 20 could also be fiat.
  • the upper surface 21 is in a horizontal plane so there is no horizontal thrust component on the arm 1 in the active position thereof.
  • the other end of the rod 19 is hingedly connected to a control toggle lever 22 by a pivot 23 and on which pivot is mounted a hook 24 capable of engaging with its free end 26 an abutment 25.
  • the lever 22 in turn is pivoted at 27 to the arm.
  • the inactive position of FIG. 3 in which the pressure between the upper and the lower rollers is at a minimum (very near zero, but at any rate slightly higher than zero)
  • the abutment 25 is defined by a shank 33 having a threaded portion for receiving a nut 32 and a coil spring 34 is located between a fixed element 35 and the nut. By the proper manipulation of the nut, the vertical position of the abutment 25 can be adjusted.
  • the invention provides for the adjustability of the position of the supporting member 6.
  • the supporting member 6 is angularly shiftable about the shaft 7.
  • the supporting member 6 is defined by two components 6' and 6" whereby the individual arms may be mounted on or removed from the shaft 7 thus avoiding the necessity of dismantling the shaft 7 per se for maintenance or other reasons.
  • the lower component 6 cannot rotate on the shaft 7 due to a longitudinal spline 36 which engages a tooth or projection 37 formed on the component 6'.
  • the same results can be achieved by a conventional key connection.
  • the upper component 6" is connected to the lower component 6' by means of two screws 38 passing through two pins 39 carried by the lower component 6 and threaded into two pins 40 carried by the upper component 6".
  • the four pins are mounted to be capable of rotation so that by tightening or loosening the screws 38 respectively, permits the upper component 6 to rotate and thus displace the arm 1 parallel to the drawing frame in a forward or rearward direction with respect to said frame for obtaining a convenient adjustment of the upper rollers with respect to the lower rollers during assembly.
  • the modification of the arm 1 shown in FIG. 7 allows the two parallel positions of the arm as shown in FIGS. 2 and 3 (and vice-versa) to be obtained.
  • one arm of a bell crank 42 is pivoted to the end portion 18 of the rod 19 as at 41, while the other arm is pivoted at 44 in a vertical slot 45 provided in the upper component 6".
  • the angle of the ball crank is pivoted at 43 in a horizontal slot 46 in the component 6".
  • said supporting arm comprising a casing defined by a web and a pair of flanges extending perpendicularly from the web, means pivoted to the flanges for carrying each upper roller, spring means biased between each pivoted means and the web normally urging the upper rollers against the lower rollers, a supporting member for the arm and means cooperable with said arm for displacing said arm from a working position to an inactive position parallel to said working position and vice versa, said cooperable means including at least one rod having opposite ends, said rod being mounted within the casing, a manipulating lever pivoted to the casing, the manipulating lever being pivoted to one end of the rod the other end of the rod having a horizontal lower face and a sloping upper face, a first pivot carried by the flanges of the casing and movable in a vertical slot provided in the supporting member to allow the arm to move to an
  • the textile dressing and spinning machine as claimed in claim 1 including a hook pivoted to the means pivoting one end of the rod to the manipulating lever and an abutment engageable by the hook for holding the arm in itprworking position.
  • said abutment includes a shank, a nut threaded onto the shank, a fixed member having an aperture through which the shank may move and a spring biased between the nut and fixed member whereby manipulation of the nut adjusts the position of the abutment relative to the hook.
  • the textile dressing and spinning machine as claimed in claim 1 including a fixed shaft, said supporting member having upper and lower components, said lower component being nonrotatably mounted on said fixed shaft, said upper component being spaced from said lower component and capable of rotation relative to said fixed shaft, and means connecting the upper and lower components defined by cylindrical blocks on each component having axes parallel to the axis of the fixed shaft and screw threaded studs threaded into said cylindrical blocks.
