Holding Devices Patents (Class 59/34)
  • Patent number: 4718592
    Abstract: An apparatus for discontinuously and simultaneously soldering an ornamental chain on two locations and with recovery of the cores which hold the loops, comprises a reel (2) for winding and unwinding the chain to be soldered, a pair of rollers (3,4) for advancing the chain, a movable and rotating vice for carrying the chain to the soldering device. The latter comprises two flame injectors, arranged opposite one to the other and acting on the loops of the chain, a pair of vertically movable clamps for holding the chain during the soldering operation, in the two predetermined locations. Finally after the soldering operations, the cores are removed from the chain and are separately collected.

  • Patent number: 4658576
    Abstract: A device for feeding in parallel of ornamental chains to an operative unit of a machine suitable for realizing the bonding of the chains, including a mechanism for the transport of the chains towards the operative unit arranged for the engagement with side by side links of the chains and for obtaining the simultaneous and intermittent advancement without modifying the symmetry of their reciprocal position with respect to the advancement axis. The transport mechanism, comprising in particular needle-shaped members, are provided with a reciprocating translational motion in the forward direction and a reciprocating lifting and lowering motion in an orthogonal direction.

  • Patent number: 4349060
    Abstract: The present invention relates to an anti-skid device for improving the traction of a wheel on an automotive vehicle on the ground. The invention relates also to a method of producing such anti-skid devices. The anti-skid device comprises at least one chain intended to run along the wall(s) of the tire and a plurality of chains intended to surround the entire tread face of the tire. The various chains are interconnected. The interconnection is provided by welding a certain number of neighboring links of two adjacent chain lengths together. The chain length may preferably be equipped with additional gripping elements welded on at least some of the links.

  • Patent number: 4185454
    Abstract: A device for inserting a link stud into a chain link to permit subsequent fastening of the link stud in the chain link in the region of the stud and/or by welding same. According to the invention, a pivotably mounted arm is arranged in operative connection to a stud fastening station, the arm carrying at its free end an operable holding means for holding said link stud and being pivotable back and forth between a collecting position adjacent a link stud feeding device and a delivery position adjacent the stud fastening station, and the holding means is resiliently mounted at the free end of the arm so as to enable guiding of the holding means into a well-defined position relative to a chain link situated in the stud fastening station.

  • Patent number: 4149058
    Abstract: For the successive welding to immediately consecutive links of a chain at a welding station, the chain is advanced to bring each link in turn to the welding station, the links flanking the link to be welded are positioned in a common plane perpendicular to the orientation of the link to be welded by orienting edges of two guides disposed to respectively opposite sides of the welding station, and each guide is constituted by a pair of webs spaced from its respective orienting edge, and arranged to support the straight sides of alternating chain links, and a region between the webs and the orienting edge in which the chain is free to rotate or twist about its longitudinal axis.

  • Patent number: 4133999
    Abstract: For the successive welding of the joints of consecutive links forming a link chain, the chain is advanced in a chain welding machine to bring a link to be welded directly below a welding position; the two links flanking the link to be welded are aligned in a common plane of alignment while a tensioning force is applied to the chain parallel to the direction of chain advance. Thereafter, the link to be welded is raised into a welding position in a plane disposed at 90.degree. to the plane of alignment. Subsequently, the link is immobilized in the welding position and its joint is welded. Upon completion of the welding step, the just-welded link is lowered from the welding position.
