21 Claims. (Cl. 66-89) This invention relates to improvements in straight knitting machines for knitting fashioned stocking or other blanks and more particularly to mechanism for universally controlling the fashioning mechanism of such machines.
In straight knitting machines of the type for knitting fashioned fabric blanks such as stockings, the selvage edges of the blanks are fashioned by varying the endwise movement of the yarn carrier rods and the narrowing point combs. The endwise movement of the carrier rods is controlled by end stop devices-carried on threaded spindles and the point combs are moved by nuts also carried on threaded spindles. in either directionto vary the position of the stop devices and comb operating nuts by pawl and ratchet devices.
In the usual practise, the spindles for the carrier rod stop' devices are moved in either direction in two needle steps and the spindles for operating the point comb nuts are moved in the narrowing direction in one or two needle steps and in the widening direction in one needle steps. Also, the point comb nuts are moved idly in the widening direction in one needle steps. The sequence of operations of the point comb nuts and particularly the idle movements of the nuts is frequently varied to produce different fashioning mark effects along the edges of the fabrics. fashioning'operations is controlled by selecting means, which in turn is in part controlled by the movement of the end stop devices and in part by the pattern chain devices of the machine. each variation in the sequence of steps to fashion the selvage edges of the blank usually requires extensive changes in the selecting means in addition to a rearrangement of certain of the control buttons on the pattern chain resulting in a considerable loss in time and pro-.
duction.
Also, during the fashioning of the various parts of the blanks, the combs must be repositioned to vary the number of points in the fashioning process. To so vary the position of the point combs, the spindles must be manually rotated, which action is performed several times during the production of each set of blanks and at the completion of a set of blanks, the spindles must be similarly manually rotated to return the carrier rod end stops and the narrowing point combs to starting position for the start of the next set of blanks.
It is an object of the present invention to provide novel means in a straight knitting machine which permits a variation in the fashioning sequence without changing the operating and controlling parts and with a minimum of time spent in adjustments of themachine.
Another object of the invention is' to provide means to automatically reset the point combs of a full-fashioned knitting machine for knitting stocking or other fabric blanks to vary the number of narrowing points in the fashioning operation in the different portions of the blanks.
A further object of the invention is to provide means The spindles are rotated.
The movement of the spindles for the various However, in the known machines 2,374,557 Patented. Feb. 24,-1Q59 in a full-fashioned knitting machine for automatically controlling the operation of the narrowing mechanism to fashion stocking fabric blanks, to reset the narrowing mechanism to perform the different fashioning operations, and to return the narrowing mechanism to starting position at the completion of the fabric.
With these and other objects in view which will become apparent-from the following description and the accompanying drawings, the invention resides in the novel elements, features of construction and arrangement of parts in cooperative relationship as hereinafter more particularly pointed out in'the claims.
