Definitions

  • This invention relates torollin'g mills and has for 'its object to provide improvements "each'of different pitch and engaged by a cooperating nut, and means'are provided for operating selectively either one of the nuts to actuate the feed spiral.
  • two sets only of threads may be employed, one set of normal pitch, and the other of a shorter pitch for use when startingthe work in the rolls.
  • the same feed-spiral may be employed for rolls of diiferent diameter which involve a greater or a lesser travel of the work, thus economizing in time in setting up the machine and reducing first cost of the parts thereof.
  • the different threads may be out upon the same portion of the feed-spiral and may consequently intersect one another, and have the same, or opposite angles of inclination. This allows the several nuts to be mounted closely adjacent to one another and thus reduces the length of the housing required to carry them.
  • the pawls may be in the form of plungers radially disposed around the ratchet teeth on the nuts, and Cam may be provided on members rotatable, manually or otherwise, around the nuts to lift the plungers against the action of springs, the mechanism being "the drawings.
  • ldlgure 2 is a transverse s'ection of which the left hand part is taken on the line 2, 2
  • the usual housing B for thenut C'which engages the first feedspiral is lengthened to receive also the nut
  • Each nut has on its periphery the usual ratchet teeth C and the.
  • pawls for each are in the form of radially disposed plungers D, pressed inwardly to the ratchet teeth by means of the springs D Three such pawls may be employed for each nut and each pawl has formed in its side a notch D A.
  • Notches E are formed in the projection E and upon their bottom surfaces E rest the outer sides of the notches D in the plungers D, when the latter are at their inner position radially.
  • each feed-spiral constituted by a quick-pitch threaded member, the pitch of one adapted to cause substantially .90 of twist of the carrier and work during its normal full travel, the pitch of the other adapted to cause a similar degree of twist with a shorter travel of the work, a co-operating nut, immovable endwise, for each of said feed-spirals, a pawl for each nut engaging ratchet teeth thereon,and arranged to permit rotation of either nut during the forward stroke of the carrier and to hold either stationary on" the return movement thereof,
  • a feed-spiral member coaxially mounted. with the work-carrier, and travelling with it, two. sets of threads upon said feed-spiral member, one set adapted to cause an angular twist of the carrier through substantially 90, during the full travel of said carrier, the other adapted to cause a similar twist during a shorter travel of the carrier, each set of threads engaged by a co-operatii'ig nut, said nuts being situated adjacent one another and immovable endwise, the threads engaged by one nut extending over the part of the feed-spiral member carrying the threads engaged by the other nut, pawls engaging ratchet teeth formed on the periphery of said nuts and arranged so that the nuts can rotate freely during the forward movement of the carrier, and either nut at will can be held against rotation during the return movement of the carrier, cams engaging the pawls upon each nut, and gearing actuating said cams whereby at will one nut" only at a time can be operatively
