CORDER FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 261,549, dated July 25, 1882..

To all whom it may concern:

Be it known that I, FRANK HAND, of Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful ImprovementsinCordersfor Sewing-Machines, of which the followingis a specification'i This invention has reference to an improved corder for sewing-machines, by which the uniform and accurate cording of the fabric is obtained, the corder being furthermore quickly applied and removed and retained in position at the exact point where it is required to perform its work.

The invention consists in the combination, with a'suitable corder-arm, of a presser-foot having parallel longitudinal grooves and a knife-like guiding-blade projecting beyond the grooves and body of the foot in line with the ridge between the grooves.

Theinvention consists, further, in the combination, with a suitable corder-arm, of a presserfoot having parallel grooves and a knife-like guiding-blade projecting beyond the grooves and body of the foot in line with the ridge between the' grooves, said blade being curved at the end to facilitate the feeding and creasing of the cloth.

The invention consists, further, in a corderarm, the free delivery end of which is provided with a straight grooved guide-heel, which extends parallel, or nearly so, with the feed, the groove in said heel being open at the front and tapered toward theneedle, whereby said heel is alapted to guide the cloth as well as the cor The invention consists, further, in an acutangnlar corder-arm, one member of which is provided with a flat perforated butt adapted for attachment to the slide-plate and slightly inclined upward from said plate, while the other member is provided with suitable cordguides, the attaching and delivery ends being in line with and apart from each other in the direction of the feed.

In the accompanying drawings, Figure lrepresents a perspective view of my improved corder for sewing-machines, represented in the act of cording. Fig. 2,ist a, front view of the corder with a part broken off. Fig. 3 is a de tail horizontal section on line 00 m, Fig. 2. Fig. 4 is a plan view of the corder-arm, partly in section, of the outer tubular end; and Fig. 5 is a detail bottom view of the presser-foot.

' Similar letters of reference indicate corre- 'sponding parts.

Referring to the drawings, A represents the resser-foot, and B the corder-arm, which together form my improved cording attachment forjsewing-machines. 'The presser-foot A is attached, in the usual manner, by means of a socket and set-screw, to the presser-bar of the sewing-machine, but is provided at its under side with two longitudinal grooves, a, parallel to each other, and with a thin knife-like blade, b, which extends forward beyond the grooves and body of the presser-foot in line with the rib or ridge b: between the grooves a. The front edge of the presser-foot A, as well as the front end of the blade I), is rounded off, as shown in Figs. 1 and 5, so as to prepare the fabric and cord for an easy entrance to the grooves and render them less liable to catch as they enter the grooves. The corder-arm B is made of V shape, and attached by its flattened rear or butt end to a slide-plate, B, of the sewing-machine, extending transversely across the same, near the front end thereof.

From the butt -end the corder-arm extends sidewise in a straight line away from the slideplate, being abruptly curved at its middle portion or apex of the V and then continued in a slightly-curved line toward the presser-foot, the free end being thus at some distance back of the butt end, as distinguished from U- shaped corder-arms heretofore in use, in which the free end is arranged vertically above the lower or butt end. The connection of the corder-arm B with the slide-plate B has the advantage that not only the corder-arm is quickly and accurately placed in its proper relative position to the presser-foot, but it has also the advantage that it may be instantly removed when not required. The free outer end of the corder-arm, being back of the butt-end,

has the advantage that thebutt-end isout of side of the projecting blade of the presser-foot. The corder-arm B is further provided with one or more ring-shaped cord-guides attached at proper distances from each other, so as to take up the cord and hold it in the proper position for the work. The body of the corder-arm B, at the curved tubular end d, is made gradually tapering. The heel e, at the delivery end of the corder-arm, is tapered toward the needle, and has a flaring groove enlarged toward and open at its forward end, the sides of which groove assist in guiding the fabric as well as the cord.

The operation of my improved corder is as follows: The cord is passed through the guides of the corder-arm and placed into proper position in the groove of the presser-foot to the right of the projecting blade. On the descent of the needle the stitches are formed alongside of the cord in the fabric, while the heel forms the guide and places the fabric in proper position for the needle. When one row of cording is laid down the next row is formed in the same manner. In this case, however, the groove on the left side of the blade straddles the already stitched line of cording, and forms thus, in connection with the blade, a steady and reliable guide for properly laying down the next adjoining cord. This is continued from the right toward the left with great regularity, so that a uniform and accurate cording of the fabric is obtained. As the corder-arm extends from the slide-plate to the right of the fabric, and is made long enough for most purposes, it is not in the way of the fabric, which can thereby be closely observed and its regularity controlled. It is obvious that the corder may be adapted for attachment to the presser-foot of any sewing-machine without changing the essential feature of the invention.

The corder-arm, instead of being tubular at the end, may also be made tubular throughout ior guiding the cord, though I prefer to make it solid with a tubular and partly-open end, as

it is thereby stronger and more durable when in use.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a cording attachment for sewing-Inachines, a presser-foot having parallel longitudinal grooves and a knife-like guidingblade projecting beyond the grooves and body of the foot in a line with the ridge between the grooves, in combination with the corder-arm, substantially as described.

2. In a cording attachment for sewing-machines, a presser-foot having parallel grooves and a knife-like guiding-blade projecting beyond the grooves and body of the foot in line with the ridge between the grooves, said blade being curved at the end, in combination with a corder-arm, substantially as set forth.

3. A corder-arm having a tubular cordguide near its delivery end and a guide-heel parallel, or nearly so, with the direction of the feed, said guide-heel being provided with a groove which is open at the front and tapered toward the needle, whereby said heel is adapted to serve as a guide for the fabric as well as for the cord, substantially as described.

4. An acutangular corder-arm, whereof the attaching member is provided with a flattened perforated shank adapted to fit the slide-plate and is slightly inclined upward from said shank, and whereof the cord-delivery member is provided with suitable cord-guides, the attaching and delivery ends of the arm being in line with and apart from each other in the direction of the feed, substantially as described.

In testimony that I claim the foregoing as my invention T have signed my name, in presence of two witnesses, this 14th day of September, 1881.

FRANK HAND.
