Definitions

  • This invention relates to improvements in pressure devices for the roll heads in drawing frames, comprising a weighting arm pivoted on a pin to the frame and provided with holders which carry the top rolls.
  • Elastic elements such as springs or a fluid pressure hose supported by said pin and subject to pneumatic or hydraulic pressure, may be provided for producing the weighting load.
  • the latter suitably may act on a bearing pin of a swingable arm pivoted to the weighting arm and,
  • the spring means may be supported, when the top rolls are not loaded, under preliminary tension on a stud connected to the said pin.
  • Fig. 2 a second form in a similar view
  • Fig. 3 a top plan view, partly in section, of Fig. 2, and
  • Fig. 4 represents a third form in a view similar to Fig. 1.
  • the front portion of the weighting arm I is composed of side walls and a connecting wall extending laterally from the upper edges of the side walls and, thus, is U-shaped in cross-section, while its rear portion is formed by two vertical walls only.
  • the latter are bored for reception of a support pin 2 which extends the entire length of the frame.
  • Two holding plates 3, which are disposed intermediate of the said vertical wall and each of which is provided with a nose 4, are fixedly connected to the pin 2 and secure the arm I against lateral displacement on pin 2.
  • the said two plates 3 are interconnected by or integral with a saddle 5 which is semi-cylindrical and is lodged on pin 2.
  • the said saddle could be a full or I closed ring.
  • the holders 6, l and 8 of the top rolls A, B and C also are disposed intermediate of the two vertical walls of arm, I.
  • a swingable arm 9 is pivoted on a pin III to arm I, and its rear portion is shaped substantially as a semi-circular hollow body having side walls.
  • a detent roller II is rotatably mounted on a pin secured to the two side walls of the said rear portion of swingable arm 8.
  • the said side walls are each provided with a beak-like projection I2;
  • a spring-wire I3 bent off at various points, is provided for producing the weighting load or pressure.
  • One end portion of the spring I3 extends through a transverse bore of pin 2 and, at the same time, an aperture in the saddle 5 of the two discs 3, thus locating the latter on pin 2.
  • the free end of spring wire I3, which permanently is subject to a certain preliminary tension, abuts against a stop stud I4 secured to the holding discs 3 when the swingable arm 9 has been swung upward and when the top rolls A-C of the drawing head thus are not weighted.
  • one leg of a torsion rod I5 which is bent oil at various points, is inserted into a longitudinal groove I6 of the pin 2; the one end portion of rod I5 being anchored in a cross bore I! of pin 2.
  • the swingable arm 9 has been swung upward, the rod I5 is subject to a. preliminary torsion through a stop stud I8 secured to the two holding plates 3'.
  • the pin 2' is tubular and houses a fluid pressure hose I9 which extends over the entire transverse width of the frame and is subject to pneumatic or hydraulic pressure.
  • a fluid pressure hose I9 which extends over the entire transverse width of the frame and is subject to pneumatic or hydraulic pressure.
  • a stationary stop 23 provided inside the latter limits the rocking move-.
  • the top rolls A-C rest, in the nonweighted state of arm I, on the bottom rolls D--F under the dead weight of the pressure device; the swingable arm 9 being slightly raised.
  • the free ends of the springs I3, I5, which are prestressed, then abut against thestop studs I4 and I8 respectively.
  • the lever 20 then is urged upward against stop 23 through the pressure hose I9.
  • the load may be easily and readily applied and removed, by means of the arrangement described, by correspondingly manipulating the arm 9.
  • the weighting-arrangement according to my present invention affords a well set, uniform appearance to the drawing frame, and substantially facilitates its operation, since levers and stirrups are avoided in front, intermediate and in the rear of the drawing rolls. Further advantages of the form of invention shown in Fig. 4 are that the pressure of the top rolls against the bottom rolls may be readily adapted to the nature of the fibrous material to be worked by varying the pressure of the fluid in hose l9, and that all the drawing heads of the frame may be loaded and unloaded from a central point by raising or low ering the pressure of said fluid.
  • Weighting apparatus for textile drawing apparatus comprising a weighting arm, a plurality of upper drawing rollers having shafts. said weighting arm carrying a plurality of holders for the shafts of said upper drawing rollers, a support pin, said weighting arm being pivotally mounted on said support pin, elastic pressure producing means carried by said pin, and means contacting the weighting arm for applying the elastic pressure thereto for loading the weighting arm and, thus, the rollers carried thereby.
  • Weighting apparatus in which the elastic pressure producing means includes a spring wire, andln which the support pin is provided with a recess accommodating a part of said wire.
  • Weighting apparatus according to claim 1 and in which the elastic pressure producing means includes a spring member having a straight portion lying parallel to the axis of the support pin, said support pin being provided with a longitudinal groove in which said straight portion of the spring member lies, for application of pressure to the spring from the said support pin.
  • Weighting apparatus in which the support pin is hollow, and the elastic pressure producing means is a flexible tube located in the hollow of said hollow pin, said hollow pin having an opening in its wall, and the means for applying the elastic pressure to the weighting arm comprises pressure trammission linkage extending through the opening in the wall of the pin and contacting the flexible tube.
  • Weighting apparatus for textile drawing heads according to claim 5 and in which there is provided a plurality of retaining plates fixedly mounted on said support pin between the side walls of the weighting arm, said plates each being provided with a nose on its periphery which serve as stops, the said second arm having projections positioned to engage the noses of said plates when swung upwardly so as to retain the weighting arm in a raised position removed from its operating position.
  • Weighting apparatus for textile drawing heads according to claim 5, and in which the means for producing elastic pressure comprises a flexible tube containing pressure fluid, said support pin being hollow and said tube being disposed in saidhollow pin, a lever having two arms and having pivot means located between the side walls of the weightingarm, a pair of spacedapart plates fixedly mounted on the support pin, said pivot means extending between said plates.
  • said lever bearing with one of its lever arms against said tube and with its other lever arm against said second arm journaled on the weighting arm to transmit weighting forces produced by the pressure tube to the weighting arm.
  • weighting apparatus for textile drawing heads according to claim 5 and in which the weighting arm is provided with a transversely extending rib, between its two side walls, said second arm having an abutment positioned to engage said transversely extending rib of the weighting arm when said second arm is swung upwardly so that the weighting arm by engagement of the abutment of said second arm with the rib of the weighting arm will also be swung upwardly.
