OVEREDGE SEAM.
SPECIFICATION forming part of Letters Patent No. 613,577, dated November 1, 1898.
Application filed November 9, 1896. Renewed April 4:, 1898. Serial No. 676,477. (No model.)
To to whom it may concern:
Be it known that I, HERMANN A. KLEMM, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Overedge- Seam Stitching, of which the following is a specification.
My invention relates to the formation of overedge seams used in sewing together the edges of furs and other goods; and said invention consists in an improved stitch, as hereinafter fully described and claimed, the object being to produce a comparatively secure lock-stitch which cannot readily ravel.
Referring to the accompanying drawings, Figure 1 represents a plan view of the feeddisks, needle, and looper of an overedge sewing-Inachine,indicatingthemovements. Fig. 2 represents an elevation of Fig. 1, also indicating the movements. Figs. 3, at, 5', and 6 illustrate perspective views of the looper, the needle, and the goods, showing the successive steps in the formation of the stitch, as will be hereinafter fully described.
A represents the inner feed-disk, and B the outer feed-disk, of an overedge sewing-ma chine.
0 represents the needle, which is actuated in a straight-line reciprocating motion, so as to puncture the goods represented at E at each intermission of feed motion of the disks A B in the usual manner.
D represents the looper, which is actuated with a compound motion, so as to move it into the successive positions of horizontal motion represented at 1 2 3 4 in Fig. 1 and in the positions' of vertical motion represented at 1 and 4 in Fig. 2. The looper D differs from ordinary loopers, such as used heretofore, in having a concave formation at 5 and an eye 6 below the heel of the looper, whence the binding-thread 7 is received and passed under the spear 8 and upward through the eye 0, so as to present a loop of the binding-thread 7 over and across the concave upper surface 5 when the parts are in the position shown in Fig. 3. The sewing-thread 10 is fed under the needle 0 and upward through its eye 11 to the goods. The looper D is actuated so as to be depressed below the line of the needle when at the position 1, Figs. 1 and 2,whereby the needle may pass over the concave surface 5 of the looper and take the loop of the binding-thread from the top of the looper, and the looper is then retracted and raised, moving to the position 2, Fig. 1, and carried over the goods E to the position 3, the needle in the meantime puncturing the goods, and at the initial retracting movement of the needle the looper advances to the position 4, Figs. 1 and 2, where it is depressed only enough to pass above the line of the needle and take the loop of the sewing-thread presented by the slack above the needle. The action of the stitch is as follows, referring to Figs. 3 to 6, inclusive: In Fig. 3 the looper D is represented as having taken the loop 10 of the sewing-thread 10 and carried it over, presenting the loop 7 of the binding-thread 7 through said sewingthread loop 10 preparatory to the entrance of the needle 0 across the upper surface of the looper at the concave portion 5, for which purpose the looper is depressed below the line of the needle, as aforesaid. The needle then advances and takes theloop 7 and the looper is retracted and raised, as illustrated in Fig. 4, crossing the loop 7 upon itself, forming a twist, which remains a permanent feature of the stitch, as seen on the reverse side of the goods in Fig. 3. The continued advancement of the needle will introduce the next sewing-thread loop 10" through the twisted loop 7 and through the goods, as seen in Fig. 5, the subsequent retraction of the needle allowing the looper to take the sow ing-thread loop 10" by crossing above the line of the needle, as seen in Fig. 6. A stitch is thereby formed wherein the sewing-thread, having its loops passed through the goods, has a binding-thread formed with twisted loops passed through the loops of the sewing thread, which loops of the sewing-thread are passed through said twisted loops of the bind ing-thread, producing a lock-stitch which cannot readily ravel by reason of the knot formed by the said twisted loops on the sewing-thread.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is' p A seam comprising one or more pieces of goods and two threads, the one thread lying Signed at New York, in the county of New in twisted loops on one face of the goods near York and State of New York, this 17 th. day of IO the superimposed edges, and the other thread October, A. D. 1896.
having a series of loops each loop of which v T T 7 1 5 passes through one of the twistedloops of the HERMAL L IXLLMM' first thread and through and over the edges Vitnesses:
of the goods and around the succeeding twist- CHARLES L. MALCOLM,
ed loop. HENRY F. PARKER.
