  • Patent number: 3958608
    Abstract: The present invention relates to a shedding drive arrangement for a loom, with a dobby driving the upper and lower sheds symmetrically and with a coupling arrangement coupling the rockers of the dobby with the weaving shafts to produce a non-symmetrical shed movement. By "rockers" or jack levers there are generally understood elements which transmit the driving movement produced by the dobby and available at its output side.

  • Patent number: 3936024
    Abstract: A carrying structure for supporting, for example, cable ducts, comprises vertical bearers from which project disengagable, horizontal bearer arms. Each bearer arm has at least two hooks adjacent one end thereof, which hooks, when inserted into corresponding holes of a vertical row of holes formed in a vertical bearer, engage the bearer arm with the vertical bearer. The hooks of an arm are integral therewith and project laterally of the arm surface which is in face to face relation with the hole-defining surface of the vertical bearer when the arm is engaged with the bearer. Each hook has on one of its side edges a lateral support surface above the vertical portion of the hook which engages the vertical bearer on its side opposite to the main body of the bearer arm. This support surface engages a vertical side of the hole in which the hook is inserted enabling the transmission between the bearer arm and vertical bearer of horizontal moments.
