 Assignee: Crescent Hosiery Mills, Niota, Tenn. Primary Examiner-Ronald Feldbaum  Filed: Mar. 5, 1973 21 'Appl. No.: 338,396  ABSTRACT 1 The leg and foot of this sock has a two-ply construction with terry loops extending inwardly on the inner  Cl 66/178 66/194 66/183 ply and terry loops extending outwardly on the outer  I111. C1 D041) 11/00 p y so that both the Outer and inner faces of the sock  held of Search 2/239; 66/l78 183-186 have terry loops thereon. The sock is formed by knit- 66/ 171 ting a substantially straight seamless tube while forming terry loops throughout the inside of the tube. One  References C'ted half of the tube is drawn over the other half to form a UNITED STATES PATENTS two-ply tube which is joined along a fold line at the 379,831 3/1888 Sutro 2/239 upper end and the free ends-at the other end are 569,702 10/1896 66/178 aligned and joined together to form the toe of the 2,144,563 1/1939 66/182 Sock 2,183,862 12/1939 66/194 2,774,233 12/1956 Lombardi 66/194 X 6 Claims, 5 Drawing Figures TWO-PLY TERRY SOCK AND METHOD OF FORMING SAME formed in the heel, toe and sole portion of the sock although they have been formed throughout the entire inside of the sock. Also, it is generally known to provide a double sock, that is one sock positioned inside of another and with portions of the two socks being connected together, generally around the upper open end by a sewn seam. This type of double sock is usually formed to provide different types of knit material on the inner and outer faces of the sock or to'provide different colors. To form this type of double sock it is necessary to complete the knitting and formation of two complete socks, then place one sock inside of the other and join the two socks together, which is a time consuming and expensive operation.
With the foregoing in mind, it is an object of the present invention to provide a two-ply terry sock which provides terry loops on both the inner and outer surfaces to insure comfort and warmth to the wearer and to provide long life and high wear resistance characteristics to the sock.
In accordance with the present invention, the two-ply FIG. 3 is an enlarged fragmentary vertical sectional view taken substantially along the line 3-3 in FIG. 2;
FIG. 4 is a view similar to FIG. 2 but illustrating the lower toe end portion of the sock closed; and
FIG. 5 is a greatly enlarged fragmentary view illustrating the stitch structure at the juncture of the elastic cuff and the upper portion of the leg and being taken substantially in the area enclosed by the dotted rectangle 5 in FIG. 4.
The sock of the present invention is preferably knit on a circular hosiery knitting machine having sinkers or other suitable elements for forming terry loops as the yarn is knit to formstitch loops. However, it is to be unterry sock includes an inner ply with terry loops extend- I ing inwardly throughout the length of the leg and foot and an outer ply with terry loops extending outwardly throughout the length of the leg and foot. Theupper portions of the inner and outer plies are integrally knit and are joined together along a fold line at the upper end in the sock. Elastic yarn is inlaid in the stitches of the upper portions of the inner and outer plies to define an elastic cuff portion at the upper end of the sock. The lower ends of the inner and outer plies are joined to each other and closed by an overedge seam to form a toe in the lower end of the sock.
The sock of the present invention is formed in an economic manner since it is initially knit as a substantially straight seamless tube with terry loops throughout the inside of the tube. One half of the tube is drawn over the other half to form a two-ply tube which is joined along a fold line at the upper end and the free ends of each ply are aligned at the lower end of the twoply tube. The terry loops of the inner ply extend inwardly and the terry loops of the outer ply extend outwardly and the ends of the tube are closed while the two plies are joinedtogether to form a toe at the lower end of the tube.
Other objects and advantages of the invention will appear as the description proceeds, when taken in connection with the accompany drawings, in which FIG. 1 is an isometric view of the substantially straight seamless tube from which the sock is formed and having terry loops extending inwardly throughout the length of the tube;
FIG. 2 is a view of the tube illustrated in FIG. 1, with the upper end portion being drawn downwardly over the lower end portion to form a two-ply tube with terry loops extending inwardly from the inner ply and extending outwardly from the outer ply;
derstood that this sock could be knit on other types of knitting machines, if desired.
As shown in FIG. 2, the sock includes'a two-ply tube including leg and foot portions and the inner ply 10 is provided with terry loops extending inwardly througout the length of the leg and foot. The outer ply 11 is provided with terry loops extending outwardly throughout the length of the leg and foot. Thus, terry loops are provided on both the inside and outside of the sock. An elastic cuff, indicated at 12 in FIG. 4 is provided at the upper end of the inner and outer plies 10 and 11 and is formed in a manner to be presently described.
The lower toe end of the sock is formed by closing the lower end with a sewn seam while joining the inner and outer plies to each other. As illustrated in FIG. 2, it is preferred that a curved seam be formed along the dotted line 13. This seam, indicated at 14 in FIG. 4, can be formed by a conventional sewing machine of the type which is normally used to form an overedge seam and trim the surplus fabric. As best shown in FIG. 3, the upper ends of the outer and inner plies areintegrally knit and joined along a fold line.
As illustrated in FIG. 5, the seamless tube is knit to form successive courses of stitch loops of a body yarn B. A terry yarn T is knit in plated relationship with the body yarn B in the needle wales W-l and W-2 while outwardly extending terry loops are formed in the sinker wales. In the cuff portion 12 an elastic yarn E is suitably incorporated in the knit fabric. As illustrated in the upper courses of the fabric shown in FIG. 5, the elastic yarn E is inlaid in each course of the cuff portion.
METHOD OF FORMING sock bring the free ends of the inner and outer plies l0 and.
11 into alignment at the open end. A curved overedge seam is then formed along the dotted line 13 in FIG. 2 to provide what is commonly referred to as a fish mount type of toe closure including the overedge seam 14.
Since the outer portion of the overedge seam- 14 is rather bulky, the two-ply sock may be turned inside out to position the bulky part of the seam 14 on the inside before it is packaged for sale. The sock illustrated in derstood that the sock may be placed on a shaped boarding form and heated or boarded to provide some resemblence of a heel pocket or other desired shape to the sock before it is sold.
The two-ply terry sock of the present invention thus provides outer and inner terry looped surfaces which provide warmth and comfort to the wearer. Since the inside and outside of the sock are identical it may be worn with either side out and will present the same surface appearance. Therefore, when one side of the sock becomes worn, the sock may be turned and the sock may be worn a greater length of time than a conventional single ply sock. v
In the drawings and specification, there has been set forth a preferred embodiment of the invention and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation.
