J. J. CORN SEAM Filed April 10, 1935 INVENTOR Julius J. Corn ATTORNEY-5 Patented July 20, 1937 OFFIQE 1 Claim.

My invention relates to a means for uniting two pieces of fabric as by a seam, and relates specifically to fabrics of light weight and extreme fineness, particularly such fabrics as are used in 5 the making of feminine undergarments, etc.

In connection with uniting two pieces of fabric in the forming of such garments, it is important that the seam or line of joining be as trim and neat as is possible consistent with strength of 1 the joining. The smaller the seam; i. e., the less bulky, the lesser is the discomfort engendered by contact of the body of the wearer against said seam.

It is the main object of my invention to provide 15 a seam or a joining between two pieces of fabric, which will be simple and easy to make, which will be neat in finish and appearance, and which will cause minimum discomfort to the wearer.

It is a further object of my invention to provide 20 a seam or joining between two pieces of fabric secured by a plurality of stitchings, one of which is linear, and another of which is circular.

It is a further object of my invention to provide a seam or joining between two pieces of fabric 25 secured by a plurality of stitchings one of which is completely enclosed within another thereof, and out of contact therewith.

It is a further object of my invention to provide a seam or joining between two pieces of 30 fabric with a plurality of stitchings, one of which is linear, and another of which is circular; the

linear stitch being completely enclosed within the circular stitch, and out of contact therewith.

Further objects of my invention will in part be apparent from the following description, and in part be specifically pointed out hereinbelow, where I describe the seam of my invention and making the same. It is to be understood that my invention is not limited solely to the precise 40 embodiment which I show and describe, but same includes any changes or departures therefrom coming within the scope'of the appended claim.

In the drawing annexed hereto and made a part hereof,

45 Fig. 1 is a perspective of two pieces of fabric disposed as in the first stage of the process whereby my new and improved seam is made;

Fig. 2 is a similar view of two pieces of fabric after the completion of the final operation; and

50 Fig. 3 is a section through a seam or joining of my invention.

The pieces of fabric l0 and I2 to be joined are disposed one on top of the other, with their respective edges M and I8 substantially aligned, and are securedtogether at !8 by a single, simple line of stitching 20 disposed parallel to edges l4,

l and as close thereto as is possible with the 5 particular fabrics being joined. Securing the pieces to be joined by this straight-line (linear) stitching is the first step in the method by which my improved seam is formed, and results in the uniting, by an edge thereof, of the superposed 10 fabrics.

The united edges l4, it are then rolled against the body of one of the pieces, either by hand, or mechanically, into a head 22. Optionally, instead of rolling, edges M, l 6 may be folded over several times to form this bead. There. is no limitation on the amount of rolling, or number of folds, except that the bead must be comparatively small, trim and neat to avoid causing discomfort by reason of excess bulk.

The formation of bead 22 is a second step in my method, and after this has been completed, the final step is undertaken, which consists in sewing a spiral or whip stitch 2A completely around and about bead 22 and along its full length. 25

The bead 22 between the two pieces, is completely enveloped by the circularly spiral stitch 2 which may be applied by hand, or machine sewn. The first line of stitching 2B is completely hidden inside bead 22, and all that is visible in the completed seam is spiral or Whip stitch 24. A double safeguard is thus provided against opening of the seam. Primarily, stitch 24 will serve to keep the joined pieces together, but in the event stitch 24 becomes loose, or the thread breaks, linear stitch 20 will secondarily keep the pieces from pulling apart.

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

A seam uniting two pieces of material comprising a bead substantially circular in cross section in the center of which are disposed the aligned rolled up edges of the pieces to be joined, said pieces being secured together inside said bead by a line of stitching adjacent said edges, and a line of stitching running spirally around said bead and along its length, said spiral stitching confining the bead therewithin and keeping the inner stitching completely enclosed within the bead.
