  • the Weight-hook I5 is preferably shouldered drafting head of a speed frame having a weightat [5
  • Fig. 1 depicts the relative positions of the parts of the mechanism when the weighting is applied to the saddle.
  • the lever 9 has been turned rearwardly so that its cam-like toe I0 may co-act with the slot l to raise the pivotal connection 12 in the vertical slot l l this movement operates to draw the weight-connecting link l3 upwardly, raising the weight 20 through-the media of the hook l5 and the lever l6, 11.
  • the lever 9 To release the saddle 6 from the pressure of the weight, the lever 9 is turned forwardly to the position shown in Fig. 2 so that as: its cam-like toe l0 slides out of contact with the slot 1 the pivotal connection [2 may sink in the slot H-and lower the weight 20 until it is supported against further downward movement by the impingement of the shoulder l5l of the weight-hook IS with its seating 2
  • the continued movement of the lever 9 after this point has been reached has the effect of disengaging the hook M of the link l3 from the weight-hook I5, whereafter the saddle 6 and the parts supported thereby may be removed from the rollers, the link l3 being drawn upwardly between the latter.
  • Fig. 5 the application of the invention to a weighting system for three adjacent pairs of rollers C, Cl; D, DI and E, El is illustrated.
  • the saddle is articulated, being formed of two complementary portions 2
  • the two portions of the saddle arepivotally connested in known manner at .23 so as to be adjustable for use in conjunction with a wide range of roller settings.
  • the pressure of the weight is transmitted by the link l3 to a lever 9, of which the cam-like toe l0 co-acts with a groove formed by a slot formed longitudinally in the portion 22 of the saddle, so that the weighting is applied simultaneously to all three pairs of rollers.
  • link l3 it is preferred to make the link l3 from a length of spring steel or other flexible material which, by reason of its inherentresilience, will constitute a shock-absorbing or cushioning connection between the weight and the saddle.
  • improved weighting mechanism may be utilized in machines where the rollers are so closely spaced together as to render impracticable the use of weighting arrangements in which the weight-connection or link between the saddle and the weight-hook partakes of a swinging or other movement in a fore-and-aft direction.
  • the lever-and-cam device herein described and illustrated in the accompanying drawings has the additional advantage of positively determining the location of the parts in the weightapplied and weight-released positions of the mechanism, since the pivotal connection l2 betweenthe lever 9 and the link I3 passes over a dead centre in moving between those positions. Itwil1,,however, be understood that alternative means, e. g. spring-pressed catches or the like, may be provided for attaining the same result.
  • the guiding slot H of the saddle may be either vertical, as in the arrangements hereinbefore referred to, or it may be so inclined in relation to the saddle as to impart to the weighting-connecting link a rectilinear movement along a line at right angles to the line of travel of the roving or the like being drafted, so that such link may pass equidistantly between the upper rollers and between the lower rollers.
  • a saddle spanning at least two adjacent rollers, a lever having a cam-like portion mounted for movement in a longitudinal slot in the saddle, a pivot pin carried by the lever, said saddle having a transverse slot providing a guide for the pin when the lever is turned about the pivot pin, a weight supporting link secured to said pin, and said transverse slot-being so disposed as to impart rectilinear movement to the weight-supporting link during pivoting of the lever.
  • a saddle spanning at least two rollers, a weight supportinglink depending from said saddle between two adjacent rollers, a lever .movably mounted on the saddle for moving the link upwardly so that the weight may be applied to the link to apply downward pressure to the upper rollers, said saddle having a transverse slot, and a pin carried by said lever engaging said slot for positively guiding the upper end of the link in a rectilinear path during movement of the lever.
  • a saddle spanning at least two rollers, a link depending from said saddle between two adjacent rollers, a lever pivotally mounted below the rollers to swing in a plane substantially parallel to the axis of the rollers, a mass supported by said lever, means adapted to be engaged by the lower end of said link for suspending the weight of said mass, another lever pivotally mounted on the saddle for moving thelink upwardly so that the lower end thereof will engage said means and apply the weight of the mass to the saddle,
  • a saddle spanning at least two rollers, a link depending from said saddle between two adjacent rollers, a lever pivotally mounted below the rollers to swing in a plane substantially parallel to the axes of the rollers, a mass supported by said lever, means adapted to be engaged by the lower end of said link for suspending the weight of said mass, another lever pivotally mounted on the saddle for moving the link upwardly so that the lower end thereof will engage said means and apply the weight of the mass to the saddle, said saddle having a slot therein, a pin carried by the second'mentioned lever engaging said slot so as to guide the upper end 'of the link in a rectilinear path during the pivoting movement of the second mentioned lever.
