UNITED STATES PATENT OFFICE.

CHARLES A. SPRAGUE, OF BIRMINGHAM, CONNECTICUT, ASSIGNOR TO THE BASSETTS CORSET COMPANY, OF SAME PLACE.

CORDER 'FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 268,565, dated December 1882.

` Application tiled August 18, 1882. (No model.) l

To all whom it may concern Be it known that I, CHAs. A. SPRAGUE, of Birmingham, in the county ofNew Haven and State of Connecticut, have invented new Im- 5 provements in Sewing-Machine Corders; and I do hereby declare the following, when taken in connection with accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the 1o same, and which said drawings constitute part of this speciiication, and represent, in-

Figure 1,aperspective View; Fig. 2, transverse section enlarged.

This invention relates to an improvement in cord-guides for sewing-machines; and it consists in aroll arranged in the presser-foot in rear of the needle, the said roll having one or more grooves corresponding to the corded snrface, and also a iiat surface to run upon the 2o workin conjunction with the feed of the machine, so that the feeding is done between the said roll and the feed, and in details of construction, as more fully hereinafter described.

A represents the cloth-plate, B the presserfoot bar, and C the needle, of the sewingmachine. The presser-foot, instead of being arranged so that its under surface stands upon the work over the feed, carries a roll, D,

Y in a slot in the foot iu rear of the needle C.

3o That part a of theroll directly in rear of the needle presents a dat periphery, preferably roughened or ijnely serrated, and stands over i the feed E, so that the work passes over the 4work-plate and is grasped between the feed and the flat portion aofthe roll. Hence when it advances on one side or' the work the roll revolves on the opposite side. In the roll one or more annular grooves, b, are made, corresponding to the rib formed by the introduc- 4o tion of the cord, and so that while the flat part a of the roll runs close against the outer side of the cord d being introduced the rib e between the grooves runs on the opposite side of the same cord-that is, on the previous line 4of stitches made-and the next rib,f, runs on the next line on the opposite side of the second cord, it being, understood that the ribs are produced by the grooves. The presser-foot extends forward of the rolls, and is turned 5o down to form a tongueor guide, h, forward of the needle, butin substantially the same line, so as to bear against the surface of the fabric' on the side of the cord next the needle, and

| thus force the upper fabric, l, down upon the lower fabric, m, as seen in Fig. 2. This tongue 5 5 serves to hold the work down close to the needle, and so as to prevent the work liftingV when the needle is drawn up. A second and like tongue, n, extends down from the for-v ward end of the presser-foot upon the opposite 6o side of the cord d being laid, and runs upon the line of stitches on that side of the cord, as seen in Fig. 2. The cord which is being laid therefore runs between the two guides h n. By this construction of guide the lower or under fabric isv held dat upon the Work-plate, the upper fabric drawn down upon and over the cord being laid, and because of the rotating upper feed-surface there is no inclination to pucker the work, as in case of a stationary 7o presser-foot. V

lt will be understood that must have thesame ordinary presser-feet.

I claiinf l. The herein-described cord-guide for sewing-machines, consistingof the roll C, arranged in a slot in the presser-foot in rear ofthe needle, a portion of the said roll a, over the feed, flat,

the presser-foot yielding pressure as in the adjacent surface annularly grooved corre- 8o sponding to the cord to ,be laid, substantially as described. t

2. `The combination of the roll C, arranged in a slot in the presser-foot in rear ofthe needle, a portion of the said roll a, over the feed, at, the adjacent surface annular-ly grooved corresponding to the cord to be laid, with the tongue h on the presser-foot forward of the needle and extending down onto the work in line with the line of stitches being run, sub- 9o stantially as described.

3. The combination of Ithe roll C, arranged in a slot in the presser-foot in rear of the needle, a portion of the said roll a, over the feed, llat,vthe adjacent surface annularly grooved corresponding to the cord to be Iaid, with the tongue h on the presser-foot forward of the needle and extendingdown onto the work in line with line of stitches being run, and the tongue n on the presser-foot forward of the roo roll parallel `with the tongue h. substantially as described.
