UNITED STATES PATENT FFICE.
' F. E. MARBLE, OF NEW YORK, N. Y.
Specification forming part of Letters Patent No. 33,439, dated October 8, 1861.
ilo all whom it may concern: i
Beit known that I, F. E. MARBLE, of New York, inthe county of New York and State of New York, have invented a new and useful Improvement on Single or Double Thread Sewing-Machines; and I do hereby declare that the following, taken in connection with the accompanying drawings, which form part ot' this speciiicatio'n, is such a full and clear description as to enable others skilled'in the art to which this my improvement relates to make and use the latter.
My present improvement'is restricted to that class of single or double thread 'sewing-machines in which a crochet or chain or other kind of stitch is formed by the combined action of an eye-pointed needle and revolving or rotary hook or ooper, and more particularly relates in such combination to a revolving hook or looper, always traveling in the same direction when operating, for the formation of said stitch, and in which the one loop is,passed through its predecessor while bth loops are on the hook or looper, and the interlaced or-castoff loop is drawn upv or tightened by the action of the hook on the succeeding loop; also, in which cach loop is or may be twisted to open or spread. it and'to strengthen the stitch after passing the cloth to be sewed and before taking a fresh loop. Such an arrangement is shown and described in Letters Patent of the United States granted-to James E. A. Gibbs on the 2d of June, 1851, reissued My present invention, however, is an improvement upon such combination of an eye-pointed needle and revolving hook or looper, and essentially differs therefrom in a most important respect. lhus in the Gibbs combination, as referred to, the loop after it slipsoif the hook is caused to lodge in an angular recess, and is afterward twisted by a spur or cast-off arranged in relation to the hook and angular recess, so that the loop is spread for the noseiof the hook to pass through on taking a fresh loop from the needle, the preceding loop lying'in a concave portion of the hook, while the fresh one is entered by its nose, and immediately afterward the old loop is cast olf from all connection with the hook, and in a large, or loose form, to be subsequently drawn tight by the opening of the new' loop. This action exposes the oid loop,
after it has been cast off and before' being drawn up or tight, to twist and kink, or it may by the rapid action of the hook be thrown intoits path and become entangled therewith. In either case the thread will break, and thus cause imperfections in the seam, which are the starting-points for its raveling.
.lo remedy this great defect is the object of my improvement, which consists in an attachment to the hook ofagradual let-off, that causes the looper to retain possession ofthe old loop one revolution or thereabout or more from the tirst entry of the hook, and till said old loop is fully, or nearly so, drawn up or tight against the cloth bythe action of the hoo'k and needle on the new loop, and which retainerof the old loop, moreover, exercises a tension on the latter, in accordance with the action on it, through the new loop of the hook or looper, as aforesaid. Accordingly itwill be seen that by this my improvement the old loop, not `being left free, cannot kink or become entangled or disarranged while being drawn up.
To more minutely describe this my improvement, I now refer to the accompanying drawings, and which, taken in connection with what has herein already been said, and compared with the Gibbs combination," as referred to, upon which my invention is an improvement, needs but al short description to explain it.
In said drawings, Figure l represents a front View ofa single-thread chain-stitch sewing-machine with ;revolving hook or looper and my improvement applied to the latter; :and Figs.
2,' 3, 4, 5, and 6, views or diagrams in illust-ra' tion of the action of the hook or looper, with its let-off attachment, at different stages in the formation of the stitch and in it-s changing' positions relatively to the needle.
The general construction and action of the machine is or may be similar' to that shown in the Gibbs patent before referred to, or of any other suitable single or double thread chain-stitch sewing-machine. Such therefore, including the action of its feeding mechanism, whichcomprises the dog a and presser b, holding the cloth in between them on the table c,
and the thread-tension devices, and other ordinary features, require no description here;
but, in this connection, it will sniiice to say A represents the reciprocating eye-pointed needle, which kin its descent carries the thread d through the cloth and below the table for the revolvinghook or looper B to catch and act upon it, as already generally described. The hookB is not only formed with a looptwisting spur, e, but is also provided at its back with an attachment or extension, C. that may have a lip,f, lat its extreme end, and which attachment or extension constitutes the tension let-oli" or retainer I have before specified as my improvement. Said let-oli' or retainer is formed by a swell on the back of the hook, extending from the nose ot' the hook for 'the fourth of a circle (more or less) in the rear of its path, and joined at its back to the base of the hook or near the base ot' the latter by a curved or straight line, g, at the outward ex tremity of which is the lipf.
The opera-tionis substantially as follows: As the needle A commences its retraction the nose ofthe hook B enters the new loop brought down by the needle, which is the position shown for the hook in Fig. 2 of the drawings. The old or former loop r-having been previously spread out or opened, as will be hereinafter explained, the hook next advances to the position shown for it in Fig.3,carryingthc new loop s through the old one, which latter still remains on the looper or on the inner portion ot' the back ot' the let-ott' C, at or near the base of the hook. rlhe hook then advances to the position shown in Fig. 4, when the old loop has slid considerably outward along the back g of the let-ott, which keeps said loop in its proper position and at a slight tension during the drawing of it up by the action of the hook on the new loop. Said hook next moves to its position illustrated in Fig. 5, when the old loop has slid farther outward and so as to or turned it, and spread or held it open for its passage in the further movement of the hook to the position of the old loop r in Fig. 2, to be acted upon by the tension let-off or retainer l, as was described for the old loop, and for the continuance or establishment of a series of chain-stitches.
Having now described my improvement, I
shall state my claim as follows:
In a combination ot' an eyepointed `needle and revolving hook or looper, used either in a single or double thread sewing-machine, providing said hook or looper with a loop-retainer as that it holds onto and controls the loop till it is drawn up by the action ot' the hook or needle, or both hook and needle, essentially as herein set forth.
In testimony whereofI have signed my name to this specification before two subscribing witnesses.
.F. E. MARBLE.
