To all whom, it may concern.:

Bc it known that I, JOHN HADFIELD, Jr., a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain new and useful Improvements in Stockings and Processes of Making Same, of which the following' is a specification.

My invention relates to improvements in stockings and processes for making the same, and the object of my invention is to provide a new process for forming stockings of the type known as full fashioned, whereby a great saving is achieved both in time and in the cost of manufacture, andan article of superiorquality obtained.

With reference to the drawings:

Figure l, illustrates a stocking made in accordance with my invention;

Fig 2, shows the upper portion of the stocking, the forming of which constitutes the first step in my process;

Fig. 3, is a view of the upper portion of' the stocking shown in Fig. 2, after it has been divided at the rear and is ready for f knitting machine.

transference to the full fashioned knitting machine, and I f Fig. 4 is a view of the upper portion of the stocking divided in part sufficiently to permit the laying out of the lower section for the transfer operation.

The present method of forming stockings of the type known as full fashioned is to knit the entire leg portion upon what is commonly known as a full fashioned stocking This is a comparatiively lengthy process, due in part to the fact that in forming the welt, the upper portion of the stocking must be turned over by han'l.

During the time that the welt is being formed, it is necessary that the machine upon which the stocking is being formed remain idle, and since the knitting and turn. ing of the upper portion of the stocking consumes substantially three-fourths of the time required to form the entire leg, itis apparent that the actua-l loss is considerable. All this will be fully understood and appreciated by those acquainted with the art.

I have discovered that by forming the upper-portion of the leg of my stocking upon a circular 'stocking knittingmachine of the type employed in the manufacture of socalled seamless hosiery,v and transferring this upper portion of the stocking from the t seamless machine to the full fashioned machine for completion of the lower portion of the leg, I am able to obtain a considerable saving both in time and actual cost of manufacture, and at) the same time put `out an article which is superior to the stocking formed entirely upon the full fashioned machine.

In carrying out my process, it is necessary, first, that the circular machine employed in knitting the top of the stocking shall have the same number of needles as the full fashioned machine employed for knitting the lower portion of the leg, and that the two machines shall knit fabrics which in appearance are similar. This can be easily arranged fo-r. In following out the process,

therefore, I first form upon the said ciry gitudinal wale or other guide line formed,`

as indicated in the drawings by the numeral 4f. After the tubular blank has been opened, as shown in Fig. 3, it is ready to be transferred to the full fashioned knitting machine upon which the lower portion 3 o-f the leg is formed' as a fashioned fiat-knit web, and a loose course or transfer line 5 formed in the blank constitutes a guide whereby the transfer may be yswiftly and accurately made. In the transfer, all the stitches or loops at the lower edge of the circular knit blank are passed onto the needles of the flat machine, the juncture between the two leg sections of the nished 1GO article being uniform.

The upper portion of the stocking which is formed upon the said circular machine is substantially similar to the corresponding upper portion ofa stocking knitted upon lobtained by my process is, in the essential features, exactly similar to the stocking o the ankle results'.

knitted wholly upon the full fashioned machine. rlhere are, however, certain particulars in which a stocking made in accordance with my invention is superior to the ordinary full fashioned stocking. One of the main diiculties experienced in the manufacture of seamless hosiery is the fact that in order to obtain proper relative proportions in the lower portion of the leg which lies around the ankle and in theextreme upper portion of the leg, it is necessary to limit the circumference of the upper portion of the leg. If this upper portion of the leg is made larger than is ordinarily the custom, the ankle must be correspondingly enlarged, and a stocking which bags around Even in full fashioned stockings of the usual type, there is as a rule insufficient provision made at this point, and the stockings are frequently found to bind the wearer at the top. It is, in fact, extremely hard to-find a stocking which 'will' meet all requirements, and a happy mean is-in most cases the best that kcan be realized.` It is a fact, however, that although the circular knitting machine employed for forming the upper part of my stocking has the same number of needles as the full fashioned machine which forms the o lower portion thereof, and though the fabrics of plain knitting formedupon the two Inachines are apparently identical, yet the upper portion of the leg of a stocking made 1n accordance with myl invention has a greater stretch and can encompass a greater area than astocking knit in its entirety upon the full fashioned machine employed to form the lower portion of the leg of my stocking. This difference in` apparently identical fabrics is 'due for most part to the needles used in the two machines, the circular machine of the type best adapted for practicing the present invention using latch needles and the flat machines using spring beard. As a consequence, I obtain a stocking which is capable of wider application and moregeneral use than the stocking formed complete upon the full fashioned machine. l

If still further exibility is required, moreover, it yis possible upon thevcircular knitting machine to form the inside of the .Weltvof a fabric less closelyknit than that of the rest of the stocking, and thiswill afford even greater flexibility to the welt while not 'detracting from the appearance of the stocking.` Furthermore, in transferring the upper portion 1 ofthe stocking to the full fashioned-machine, it is unnecessary to slit the blank completely open, it being sufficient to slit the blank for example from the bottom up asfar as the welt only, the welt being leftmtact. In this event,there will be found in my stocking an actually greater number of stitches than in 'a full fashioned stocking, the leg lof which is formed complete upon the full fashioned machine employed lto knit the lower portion of the leg of Umy stocking, since in stitching upl the back of the open blank, a number of stitches is of necessity sacrificed. Actually greater width may thus4 be obtained at the top of the stocking. l

I am able, furthermore, in my stocking to take advantage of the so-called lock stitch or anti-run-back, which is a stitch formable only upony circular machines such as I employ informing the upper portion ofy my stocking. This lock stitch is placed somewhere below the welt, as indicated in the drawings by the numeral 6, the purposebechine, and as a consequence, it is` incorporated in my completed full fashioned stocklng. i Many other Apossible advantageous feaquainted with the art.

As indicative of the great saving of time resulting from my process, I am able` to form the leg of my stocking complete in ap- 100 proximately two-thirds of the time that it takes to form the leg of a stocking upon a full fashioned machine, this' saving constituting the difference in the time that it takes to 'form the upper portion of-the stocking 105 upon the respective machines. I am also ableto avoid in the formation of my stocking considerable close and arduous work] upon the part of the operator, an'd the machine-formed welt is generally of superior 110 quality to the welt formed manually upon the full fashioned. machine.

Aside from the vactual saving in time and labor thus described, I am able to operate my machines practically continuously, with- 115 ffl' out the necessity for keeping theniidle for protracted periods, and the production'is thereby greatly increased, this actual increase o-f production -being approximately 100%.

A Since the seamless knitting machines are comparatively cheap and easy to obtain, my 125 process will particularly recommend itself to manufacturers desiring to increase their c production while belng unable or unwilling to go to the expense of purchasing more of 13 the full fashioned machinery.
