Definitions

  • a frame for warp-tying or knotting machines including at least one guide roller which can be pivoted about a vertical axis or locked against pivoting by means of a spring'biased lever engageable with a stationary slotted or notched disc and a resilient member for selectively maintaining the lever out of engagement with the notched disc. against the spring bias.
  • This invention relates in general to weaving apparatus, and more particularly to frames for warp-tying or knotting machines.
  • Frames for warp-tying or knotting machines have a considerable width and are generally extremely heavy.
  • the space available for moving the frames in and around the looms is generally very narrow, so that the frames themselves have to be designed in such a way as to be universally maneuverable.
  • An object of the present invention is'to obviate these disadvantages and inconveniences inherent in known constructions.
  • the invention provides a frame for warptying machines and the like comprising at least one guide roller which is provided with a releasable locking device which forces the guide roller to travelin but one direction predetermined relative to the frame itself.
  • FIGURE 1 is a side elevation, partly in section, of one foot of a frame incorporating a guide roller in accordance with the invention
  • FIGURE 2 is a top view of the guide roller of th invention taken along line A-A of FIGURE 1.
  • a frame 1 of the type known in connection with warp-tying and knotting machines has at least one guide roller construction in accordance with the present invention for providing rolling support for the frame.
  • the guide roller construction includes a roller or wheel 4 mounted for rotation about a horizontal axis 6 between two forks or arms 5 which are carried by an axial bearing 3 secured to support pin 2.
  • the support pin is, in turn, mounted in the frame 1 with the axial bearing 3 taking up the vertical forces on the guide roller construction and providing for rotation of the roller 4 freely in any direction with respect to the pin 2.
  • the forks or arms 5 are inclined with respect to the axis of pin 2 so that the horizontal axis of rotation 6 of the roller lies in a plane spaced from the pin 2, or at least the vertical axis thereof.
  • a cover 19 is fixed to the frame 1 and accommodates the component parts of the locking device in accordance with the invention.
  • the locking device comprises a latch plate 13 which is mounted so as to be rotatable about a spindle 12 and is rotated counter-clockwise by a spring 16.
  • a lever arm 15 is connected to the latch plate 13 for selective rotation thereof and projects upwards through a slot 20 in the cover 19. In this position, the lever 15 rests against an end 21 of the slot 20 due to the bias provided by spring 16.
  • the arms 5 supporting the guide roller 4 are secured to a locking disc 11 formed with at least one notch or groove 14 (FIG. 2).
  • the latch plate 13 drops into this notch 14 when the guide roller 4 has been pivoted to travel in a predetermined direction, and prevents it from moving in other directions.
  • a second notch 14' is advantageously formed diagonally opposite the notch 14 in the latch plate 13 so that the guide roller can be locked in at least two directions separated from each other by In order to release the guide roller, it is suflicient to apply to the lever 15 a pressure directed against the bias pressure of the spring 16, as a result of which the plate 13 is lifted out of the notch I 14, thus releasing the guide roller for free rotation.
  • the guide roller With the latch plate 13 inserted into notch 14 or 14 in locking disc 11, the guide roller is secured in a posi tion orthogonal to the frame 1 and is maintained in this position regardless of the contour of the surface over which it travels.
  • the frame can thus be moved over a straight line path with case.
  • the locking device can be released by operating the lever 15 so that the guide roller is free to rotate to permit universal movement of the frame.
  • the latch plate 13 is advantageously designed in such a way that it can also be kept permanently out of engagement with the notch 14 in cases where, for example, it is desired to bring the frame between two looms, for which purpose all of the guide rollers supporting the frame have to be freely movable.
  • the latch plate 13 has a projection or nose 17 and in a circular path of travel of which is a locking roller 18 with a resilient surface of, for example, rubber. If sufficient pressure is applied to the lever 15 in the clockwise direction, the projection or nose 17 will depress or indent the surface of the locking roller 18 to such an extent that it will move into the position shown in broken lines in FIGURE 1.
  • the spring 16, however, is of insufiicient strength to rotate the projection 17 back over the locking roller 18. Only an adequate pressure on the lever 15 in a counter-clockwise direction in conjunction with the pressure of spring 16 will return the projection 17 over the surface of the locking roller into the position in which the latch plate 13 can drop into one of the notches 14 or 14'.
  • the cover 19 (together with an overhang 19 to accommodate the latch plate 13 and the locking roller 8) is considerably longer than the space required to mount the pin 2 alone.
  • the overhang 19 is so arranged in relation to the frame that it is directed toward the opposite foot of the frame. The operator is thus able to guide the frame, for example straight to a machine room, optionally on locked guide rollers, and to release the guide rollers by operating the lever 15 with his foot at the time that increased maneuverability is required in order to bring the frame between two looms and to move it into the required position.
  • the drawing illustrates but a single guide roller construction so as to provide a simplified and as uncomplicated an illustration of the invention as possible; however, as apparent from the foregoing description four guide roller constructions would be ordinarily provided in connection with each frame, although a lesser number of lockable rollers could also be utilized to advantage.
  • a guide roller construction comprising:
  • guide roller means including a guide roller, support means for mounting said roller for rotation about a first axis, a pivot pin having a second axis transverse to said first axis, and an axial bearing interconnecting said pivot pin and said support means, and
  • said releasable locking means further including resilient means for maintaining said pivot lever means in said first position against the bias of said spring means.
  • pivot lever means includes a projection engageable with said resilient means, said resilient means being disposed in the path of said projection and deformable under predetermined pressure by said projection to allow said projection to pass to the opposite side thereof.
