United States Patent DEVICE WITH NEEDLE AND CLAMPIN G MEANS FOR MATERIAL Stephen G. Cox, Westfield, N. J. Application April 30, 1952, Serial No. 285,340

1 Claim. (Cl. 132-56) My invention relates to the placing of hairs, either of the real or synthetic variety, in the heads of plastic or rubber dolls. The method is also adaptable for the manufacture of wigs.

Heretofore many attempts have been made to insert hair in a dolls head so that the child can wash, comb, curl or dye the hair without success since the rough treatment combined with the use of water causes the hair to become dislodged.

One of the methods used in the past consists of placing hair over the dolls head then punching through the head with a split needle. This method is hit or miss and there is no certainty that enough hair will be caught by the split needle and forced into the dolls head, resulting in many holes punched unnecessarily, some containing more or less hair and others containing no hair at all.

One of the objects of my invention is to produce a head of hair on a doll which will be so firmly afiixed to the head that the hair may be combed, waved, washed or dyed without any loss of hair from the dolls head.

Another object of my invention is a method of producing a head of hair on a doll in such a manner that each stroke of a needle will positively emplace one or more hairs in the dolls head.

Another object of my invention is to produce a head of hair on a doll so emplaced that leakage into the interior of the dolls head, when the hair is washed, is impossible.

Other objects and advantages will be apparent from the specification and drawings in which:

Fig. 1 is a partial cross section of a dolls head showing the emplacement of hair;

Fig. 2 is a cross section along 22 of Fig. 1 showing the needle and emplacement device inserting hair in a dolls head;

Fig. 3 is an enlarged plan of the instrument used for emplacement of the hair.

Referring to the drawings, 1 represents spools on which synthetic hair 3, such as nylon, are wound. These spools are loosely and rotatably supported on axles 4 mounted on a rack 5.

For the purpose of insertion of hair in the dolls head I provide a scissors-like instrument having a holder 6 which is partially cut through the middle to form a notch 7 and having hole 8 drilled from top to bottom to receive a hollow needle 9 whose shank is cut away at 10 to correspond to the notch 7 in the holder 6, the purpose of which will be later explained.

The holder 6 has an offset handle 11 and at the offset has an orifice 12 pierced by a pivot nut 13 for the purpose of pivotally holding a handle 14 carrying a stopper arm 15 slightly smaller than the notch 7 and being faced along its length by a strip of soft rubber or other suitable material 16. It will be seen that when the handles 11 and 14 are opened the stopper arm 15 and facing 16 emerge from the notch 7 and when the handles are forced together the stopper arm and facing enter the notch 7 and cutaway 10 of the needle 9 closing off the hollowed portion of the needle.

Operation As is seen by the drawings, the head of the doll 17 is composed of soft rubber to which I apply a coating of glue or shellac 18, and preferably allow to set until the glue is tacky. Next it is necessary to thread a strand of hair 3 from each of the spools 1 through the needles leaving a small portion of the hair protruding below the needles. The handles 11 and 14 are now brought together so that the facing material 16 is forced through notch 7 and cutaway 10 of the needle clamping the hair 3 against the hollow needle side and holding it from vertical movement in either direction. The needles are now pushed downward, unreeling hair from the spools 1 as they descend, and are forced tthrough the head material 17 and through the tacky glue 18. At this point the handles 11 and 14 are separated relieving the clamping pressure on the hair 3 and the needles are raised to a predetermined height above the head dependent on the length of hair desired and cut by scissors, knife or other sharp instrument (as shown by out line Fig. 1) after which the handles 1.1 and 14 are forced together and the operation repeated until the entire head is covered resulting in a head of {Iran which will be irremovable after the glue or shellac as set.

It is entirely within the scope of my invention that the operation of applying cement and glue to the under side of the dolls head may be left until the last step. since if rubber or soft plastic scalps are used, the pliability of the scalp will permit the withdrawal of the needles and will retain the hair until the head has been covered at which time a cement or lacquer may be applied to the under side of the scalp.

It will be understood by those skilled in. the art that many needles may be banked on a single instrument so that one operation will implant many hairs and that it is also possible to use twisted hairs from the same reel or hair from several reels each fed through a single hollow needle so that each puncture of the needle will implant more than a single hair at one time.

It will also be understood by those skilled in the art that I have described a manual operation which by mechanical skill may be easily incorporated into a machine to accomplish mechanically all of the operations performed by hand.

Other variations in my invention may be made without departing from the scope of my invention.

I claim:

In a device of the character described, a vertically hollow needle, a holder for said needle, horizontally movable clamping means adapted to fit into a slot in said needle holder to interrupt the hollow in said needle, a movable pivoted arm attached to said clamping means whereby said vertical hollow may be obstructed or freed from obstruction by movement of said pivoted arm to free or clamp material running through said hollow needle for the purposes as described herein.
