Patented Oct. 3 1950 APPARATUS FOR FORMING DESIGNS IN NYLON STOCKINGS Elmer F. Seemuller, Philadelphia, Pa., assignor to Perforations, Inc., Palmyra, N; J., a corporation of New Jersey Application April 11, 1947, Serial No; 740,779

3 Claims.

The object of this invention is to devise novel means for forming designs in nylon fabric.

A further object of the inventionis to provide novel means to enable the manufacturer, especially in the case of stockings, to permanently form in the stockings the number indicative of the gauge. The finer gauges are more expensive, and the average retail purchaser has to depend on the representations of the dealer as to gauge. The result of this is that in some cases in order to obtain excessive profits the dealer has the goods marked with a higher'gauge. than the actual gauge of the goods. The present invention discloses a practical apparatus for the manufacturer to employ to form in the fabric the number or design indicative of the proper gauge.

'A further object of the invention is to devise novel apparatus for deforming or stretching selected loops or stitches by insertion of; points defining the number or design into them, and subjecting the deformed loops or stitches to the action of heat to permanently set them.

With the foregoing and other objects in view as will hereinafter clearly appear, myinvention comprehends novel apparatus for forming designs in nylon fabric.

For the purpose of illustrating the invention, I have shown in the accompanying drawings a preferred embodiment of it which I have found in practice to give satisfactory and reliable re- It is, however, to be understood that the various instrumentalities of which the invention consists canbe variously arranged and organized, and the invention is not limited to the exact ar rangement and organization of these instrumentalities as herein set forth.

Figure l is a side elevation of an apparatus for forming designs in knitted or wovennylon fabric.

Figure 2 is a bottom perspective view, on an enlarged scale, of a male die.

Figure'3 is a perspective view, on an enlarged scale, of a female die and a portion of its mountmg.

Figure 4 is a top plan view showing a portion of a fabric with a numeral indicative of the gauge formed therein.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings:

The apparatus has the general appearance of a press. A frame I of any desired or conventional construction has a table or article support 2 secured to it by fastening devices 3. The table at its forward end is chambered at 4 to receive a fastening devices 6. The female die has apertures or openings 1 arranged to define the particular number or other design which has been selected.

A lever 8 has one end pivotally connected with the frame at 9, and is normally retained in its raised position by a spring It) disposed between the lever and the frame. The forward end of the lever 8 is operatively connected to a shoe II as at 12 to effect the raising and lowering of such shoe which latter travels in vertical guides in. the head of the frame, the guides being shown at l3.

An electric heater l4 having any desired type of temperature control is provided with a conductor I5 which is connectible to a source of electric supply, and its side wall It has the shoe H connected to it in any desired mannen.

A male die I! has a cover plate l8 fixedto its upper end byscrews IS. The male die ll-has points-20 depending from its bottom and arranged toconform in outline to the openings of the female'die.

Themale die is detachably connected with the heater by brackets 2| or in any other desired manner.

The operation will now be apparent to those skilled in this art and is as follows:

Assuming that the dies are in position, the article to which the design is to be applied is placed over the female die and stretched out in a flat condition. In the case of a stocking, it is slipped .over the table 2 into position over. the female die. A foot treadle is pressed downwardly to move downwardly a connection 22 connected with the lever 8, thereby moving downwardly the heater and the male die carried thereby.

The points 20 pass through loops or stitches to deform or stretch them, and the heat from the heater acting through the points permanently sets the loops or stitches.

The design can be applied to the fabric in the Greige state before or after preboarding or in the finished fabric.

The design may be in the form of a letter, number, word, pictorial illustration or other insignia.

If it is desired to have the design colored, the coloring material is applied to the pointed members in any desired manner, for example by a brush, pad or color transfer device, manually or mechanically operated or by electrically controlled mechanism.

If the pointed members carry color material, the color will be applied to the selected loops as the pointed members pass through such loops to expand them.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In an apparatus for forming in a, nylon stocking a permanent identifying design, the combination of a flat female die with a series of holes distributed over a two-dimensional area in a pattern according to the desired identifying design, a framework supporting said female die, said female die being arranged in overhanging relation to the framework to permit the open end of the stocking to be telescoped over the die for the formation of the design in one thickness only of the material, a cooperating male die comprising a series of sharply pointed needles arranged in the same pattern and having their points terminating in a common plane and tapered to a size larger than the openings in the stocking formed by the loops, means for operating one of said dies relatively to the other to cause the needles, all at the same time, to enter the holes of the female die, said needles by such operation being caused to penetrate the single thickness of material placed flatly upon the female die and by direct contact with the loops through which they pass to produce a series of loop enlargements conforming to the aforesaid pattern. and means for heating the loops during the needle penetrating period to a temperature at which the nylon composing the stocking is set to set said loops in their enlarged condition and thereby form and perpetuate the desired identifying design.

2. In an apparatus for forming in a nylon stocking a permanent identifying design, the combination of a fiat female die formed with a series of holes distributed over a two-dimensional area in a pattern according to the desired identifying design, a framework supporting said female die, said female die being arranged in overhanging relation to the framework to permit the open end of the stocking to be telescoped over the die for the formation of the design in one thickness only of the material, a cooperative male die comprising a series of sharply pointed needles arranged in the same pattern, having their points terminating in a common plane and tapered to a size larger than the openings formed by the loops, means for operating one of said dies with reference to the other to cause the needles, all at the same time, to enter the holes in the female die, said needles by such operation being caused to penetrate the single thickness of material placed flatly upon the female die and by direct contact with the loops through which they pass to produce a series of loop enlargements conforming to the aforesaid pattern, and electrical heating means to maintain the needles at a temperature at which the nylon composing the stocking is set to set the loops in their enlarged condition during the needle penetrating period and thereby form and perpetuate the desired identifying design.

3. In an apparatus for forming in a nylon stocking a permanent identifying design, and wherein the loops of the stocking define preformed openings, the combination of a female die formed with a series of holes distributed over a two-dimensional area according to a desired pattern of an identifying design, a cooperating male die comprising a series of needles to enter holes in the female die and tapered to a size larger than the preformed openings formed by the loops, said female die having one end unsupported to permit the open end of a stocking to be telescoped over it for the formation of the design in one thickness only of the material of the stocking, means for operating one of said dies relatively to the other to cause the needles to enter the holes of the female die, said needles by such operation being caused to penetrate the single thickness of the stocking and by direct contact with the loops through which they pass to produce a series of loop enlargements conforming to the aforesaid pattern, and means for heating the loop enlargements during the needle penetrating period to a temperature at which the nylon composing the stocking is set to set the loops in their enlarged condition and perpetuate the desired identifying design.
