B. HARMON HAIR BAND Filed June 5, 1949 May 6, 1952 Patented May 6, 1952 UNITED STATES PATENT oEEicE HAIR BAND Bennie L. Harmon, Anniston, Ala. Application J une 3, 1949, Serial No. 96,840
This invention relates to womens hair hands, and more particularly to hair bands of the elastic type.
A main object of the invention is to provide /a novel and improved hair band which is very simple in construction, requires no rubber, and which is not adversely affected by repeated laundering or soaking.
A further object of the invention is to provide an improved womens hair band which is very simple to fabricate, which is made of homogeneous thread material, and which retains its elasticity through long periods of use, and wherein the elasticity of the band is not adversely affected by extended periods of tension nor by long periods of immersion in water during laundering or when the hair band is worn while bathing.
Further objects and advantages of the invention will become apparent from the following description and claim, and from the accompanying drawings, wherein:
Figure 1 is a top plan View of a hair band in accordance with the present invention shown in collapsed condition;
Figure 2 is a plan View of the hair band of Figure 1 in stretched condition;
Figure 3 is an enlarged detail elevational view of one of the strands comprising the hair band of Figure 1 in the normal unstretehed condition thereof;
Figure 4 is a detail view of the thread member of Figure 3 shown in its stretched position;
Figure 5 is a view showing the position of the hair band when worn.
Referring to the drawings, it will be seen that the hair `band is designated generally at Il and comprises an annular coil of highly twisted strands of cotton yarn. The yarn may be of any desired thickness, and is preferably formed of two-ply construction, each ply being individually twisted in the same direction. In fabricating yarn initially, each ply thereof is ordinarily made with a certain initial amount of twist. To produce the high-twist yarn employed in the hair band, the plies are given an additional twist which can be either right handed or left handed, depending upon the direction of the initial twist. Best results are obtained by making this additional twist four times the square root of the count for each ply. These single strands are then combined by running both ends of two bobbins of yarn, thus twisted, through another twisting operation, combining the two strands into one. If the formula of four times the square root of the count is used in the second twisting 1 Claim. (Cl. 132-46) step of each of the strands to be plied, as above described, then the preferred formula for the twist of the plied yarn is 13.40 times the square root of the count in the same direction.
For example: Suppose that a yarn is selected initially that has a count of 36. This is a medium size yarn. The square root of 36 is 6. Four times 6 gives 24 turns per inch of yarn. Therefore, the commercial 36-count yarn is given an additional twist of 24 times per inch in order to make one strand of the two-ply final product. Two strands of the additionally-twisted yarn are then combined to produce a doubled yarn. This doubled yarn by trade practice has a count onehalf the count of each component yarn, i. e., 18. The degree of twist for the two-ply yarn is determined by multiplying 13.40 times the square root of 18. The twist for the two-ply yarn must be in the same direction as the twist in the singleply yarn used.
In fabricating the hair band, the high-twist yarn is wound from a bobbin with slight tension on a reel, which by way of example may be 54 inches in circumference. Any desired number of turns of yarn on the reel may be employed, depending upon the desired nal weight of the article. After the desired number of turns have been wound on the reel, the outer or bobbin end of the skein is out and both ends thereof are tied together, using the conventional weavers knot, or other suitable knot. The ends remaining after knotting are then passed around the skein in order to prevent separation of the coils, and the l skein is taken from the reel.
Upon removal from the reel, the skein begins to kink, coil, or twirl because of the high twist. In order to effect a unform distribution of the coils or kinks, the workman inserts both hands inside the skein and pulls the skein out to a straight condition, as in Figure 2, and permits it to contract to the condition of Figure 1. This is repeated several times. The article is then completed and assumes the normal position of Figure 1. Any dyeing desired is accomplished prior to putting any twist in the yarn. The commercial yarn is bought in the color desired.
Referring to Figure 3, it will .be seen that a strand of the twisted yarn in the hair band prior to stretching the band has the twisted kinks I2 distributed substantially uniformly thereover and projecting outwardly at random angles. This gives the contracted band a generally fuzzy appearnce. The kinks interengage with the various turns of the band and provide cohesiveness for said turns. When the band is stretched, as in Figures 2 and 5, the kinks l2 are pulled out and may be reduced to very small size, as shown at I3 in Figure 4. The tendency for the kinks to return to the position of Figure 3 gives the band great elasticity, and said elasticity is not adversely affected by prolonged soaking of the band, nor by repeated laundering thereof.
As shown in Figure 5, the band may be worn over the hair in any desired manner or color as chosen by the wearer, and in accordance with the costume selected for a particular occasion.
While a specific embodiment of an elastic hair band has been disclosed, in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitation be placed on the invention except as defined by the scope of the appended claim.
What is claimed is:
A hair band formed from a plurality of contiguous pairs of annular yarn coils, each pair being of highly twisted two-ply yarn, the strands of each pair being individually twisted upon themselves in the same direction and each pair being further twisted in the same direction as the direction of twist imparted individually to each strand, so that each pair includes a plurality of normally closed and laterally extending coiled kinks with the kinks uncoiling upon manual elongation of the contiguous pairs and automatically 10 recoiling to shorten the pairs.
