4 Claims.

The invention relates to improvements in fiat knitting machinery and more particularly to means for making lace designs with a picot bar on all parts of the stocking blank, from one side 5 to the other, in the welt, after the welt or on any part of the blank; in addition means are einbodied in the same machine for making net mesh designs with net mesh bars, the same being made from one side to the other of the blank or on any part of the blank. The feature of the invention is that both the aforesaid lace designs andnet mesh designs may be made on the blank for a full fashioned hose during the knitting of the hose and without removing the hose from the machine.

In accordance with present practice, great care must be exercised and a large amount of time must be consumed in setting up a knitting machine for the formation of lace designs.

same holds true for setting up the machine for net mesh designs. It is often desirable in the manufacture of fancy hose to have a lace design on parts of the hose and to have a net mesh design on other parts. The only possible way to do this'with the present machines is to transfer the partially completed blank from one machine to another. As this operation might' have to be performed a number of times during the manufacture of'a single blank it would make the cost of the completed stocking prohibitive.

' The principal object of the present invention is to provide a simple method whereby either lace designs or net mesh designs may be formed on any desired part of the stocking without removing the blank from the machine. In this way, a very fancy and attractive stocking may be made in an elcient and economical manner.

The invention will be further described in the following specification and illustrated in the 4o drawing accompanying same and forming a part thereof. A

Referring to said drawing:

Figure 1 is a fragmentary front elevatoni' Figure 2 is an end view, the shafts lbeing in sec` '45 tion; and

Figure 3 is a Vfragmentary view of a stocking blank inwhich parts of the design are more or less ditically illustrated.

It is to be understood the invention is applicable to any standard type of at knitting machine, either. a legger or a footer, or a unit machine in which the complete blank is knit.

The reference numeral 5 designates thel lace bar which is carried bv suitable arms 6 secured to the shaft '1. The shaft'l is movable longitudi- 'The nally by any conventional form of lace-work operating mechanism.- It is also mounted in the usual manner so that it may be oscllated.

The lace bar carries lace points of picot points 8. 'Ihe points 8 operate Vin the usual manner; 60 that is, in` forming a design they transfer stitches from some of the main frame needles 9 to adjacent needles to give the lace eiect. The form of design to be made determines the positioning of the points.\ It is understood the frame needles 9 are of the known spring beard type mountedin the needle bar 10 in a conventional manner.

Shafts 11 and 12 through the medium of arms 13---13 and 14-14 carry net mesh b'ars l5 and 16. The net mesh bar 15 carries lace or'picot 70 points 17 and is of suilcient width so as to extend substantially from selvage to selvage of the stocking web or blank. The points 17 will be ar ranged on the net mesh bar in accordance with the net. mesh design being made.

The net mesh bar 16 carries points 18 and the bar is considerably shorter than the bar 15. The net mesh bar 16 isused between the high heel and heel reinforcement and on the instep portion in the foot of the blank.

The shafts 11 and 12 are movable longitudinally by the lace work operating mechanism and may be oscillated in the usual manner to engage the frame needles 9.

In Figure 3 the reference numeral 20 desig- 85 nates the upper part of the stocking blank or web, the welt being indicated at 21. The lace design 22 or any other design which extends across the blank is made with the lace points 8 after the welt, or in the welt or on any other 99 part of the stocking. The net mesh design is indicated at 23 and this design or any other vform of the net mesh design may be formed on any part of the stocking by the means heretofor described.

It is to be understood that the lace bar 5 and the net mesh bars 15 and 16 are all caused to function by the lace work operating mechanism. Inasmuch as mechanisms for moving a point bar are well known in the art for producing both narrowing and lace work effects, a description of this mechanism is believed unnecessary, and is therefore omitted.

Such changes as would occur to one skilled in the art are to be considered as coming within the scope of the appended claims.

1. A flat full-fashioned knitting machine hav ing in combination with a vseries of needles and their cooperating knitting elements, a transfer 2 point bar having points spaced at intervals lengthwise of the needle series, a second transfer point bar having points spaced at intervals lengthwise of a portion of the needle series covered by said first-mentioned bar, parallel lengthwise movable shafts having a fixed spaced relationship to each other on eachof which one of said transfer point bars is mounted to swing into and out of operative position, said bars and shafts being arranged to permit the movement of said bars alternatively into operative position when the other of said bars occupies a raised inoperative position.

2. A at full-fashioned knitting machine having in combination with a series of needles and their cooperating knitting elements, a lace point bar having points spaced at intervals substantially the full width of the fabric, a longitudinally movable shaft on which said bar is pivotally supported to move into and out of operative position, a net mesh bar having points spaced at intervals the width of a portion of the fabric, and a separate lengthwise movable shaft located in fixed spaced relationship to said first bar and on which said net mesh bar is supported to swing into and out of operative postion, said shafts and bars being arranged to permit the unobstructed movement of either of said bars about its supporting shaft into operating position when the other of said bars occupies a raised inoperative position.

3. A flat full-fashioned knitting machine having in combination with a series of needles and their cooperating knitting elements, a transfer point bar having points spaced at frequent intervals lengthwise of the needle series, a longitudinally movable shaft on which said bar is supported to swing into and out of operative position, a second lengthwise movable shaft located in fixed spaced relationship to and above said first-mentioned shaft, and a second transfer point bar having points spaced at frequent intervals over substantially the same portion of the needle series, and supporting arms for said latter bar mounted on said second-mentioned shaft to permit the unobstructed movement of said second bar about said shaft into operative position with said first-mentioned bar in its raised inoperative position.

4. A flat full-fashioned knitting machine having in combination with a series of needles and their cooperating knitting elements, three parallel endwise movable shafts mounted in xed spaced relationship to each other at varying distances from the needle series, a transfer point bar having points spaced at intervals the width of a portion of the needle series and mounted on the shaft nearest said needle series to swing into and out of operative position, a second transfer point bar having points spaced at intervals lengthwise of the needle series and including the portion covered by said first-mentioned bar and provided with supporting arms secured to the intermediate shaft to permit an unobstructed swinging movement of the bar into operative position for a raised inoperative position of said first-mentioned bar, and a third transfer point bar having points spaced at intervals substantially the full widthofthe needle series and provided with supporting arms mounted on said third furthest removed shaft arranged to permit an unobstructed swinging movement of said bar into operative position for a raised inoperative position of both said first and second bars.
