CORDING ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 653,403, dated July 10, 1900.

Application filed July 20, 1899. Serial No. 724,524. (No model.)

To all whom it may concern.-

Be it known that I, GEORGIANA ROBINSON, a citizen of the United States, residing at Orange, in the county of Essex, State of New Jersey, have invented certain new and useful Improvements in Cording Attachments, of which the following is a specification, refer ence being bad therein to the accompanying drawings.

This invention relates to cording attachments, and particularly to an attachment adapted for application to sewing-machines and to produce a product in which the cloth is tightly drawn about the cord and the stitching concealed from View.

The invention has for an object to provide an improved construction of tubular guide and feeder for disposing the cloth over the cord and holding the same in proper position for stitching.

A further object is to locate this guide relative to and in combination with a holdingfoot and needle to insure the stitching in such position that the same will be effectually concealed in the finished product and the cloth tightly held about the cord.

A further object of the invention is to provide an improved mounting for the guide whereby the same can readily be removed from the sewing-machine or adjusted in relation to the holding-foot whenever desired.

Other objects and advantages of the invention will hereinafter appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a plan of the invention in'use. Fig. 2 is avertical section on the line 2 2 of Fig. 1. Fig. 3 is an enlarged detail section upon the same line. Fig. 4 is a detail perspective of the guide and its adjustable holding-plate. Fig. 5 is a similar View of the foot; and Fig. 6 is a vertical section through the finished product,showing the disposition of the stitching beneath the cord.

Like letters of reference indicate like parts throughout the several figures of the drawin s.

in the drawings the letter A designates the table or other foundation upon which the cording attachment is secured, which in most cord to produce an ornamental effect.

instances will be the work-plate of a sewingmachine. For the purpose of illustrating the operation of this invention certain detail parts of such a machine have been shown,

; such as a presser-foot B, adjustably secured upon a rod B by means of a set-screw B and a needle 0, operating at one side of said foot. The presser-foot, as usual, operates in conneetion with any suitable form of feed-plate 1 B to produce the feeding action of the goods.

The tubular guide D is composed of a taperin g cylinder having the longitudinal slot D, extending in a substantially-parallel line with the base D of the plate. It will be seen that the .taper of the tubular guide D compresses thecord to a slight degree and also folds the cloth around the same, so that when the corded cloth emerges from the guide it is tightly drawn about the slightly-compressed cord, at which time the stitching action occurs, and the cord afterward expands slightly to completely fill the loop in the cloth and bring the line of stitching 0 directly beneath the cord, as shownin Fig. 6. To accomplish this object to the best advantage, I have found it necessary to locate the needle 0 directly adjacent to the side of the tubular guide D and at one side of the presser-foot B, which exten ds substantially parallel with the delivery end of the tubular guide. This presser-foot beyond the end of the guide 1s disposed at an angle to a straight line extending from the needle in the direction of the line of feed, so as to slightly free the goods and permit an easy movement of the same beyond the point of stitching, whereby an operator may shirr or gather the cloth uponl til e 1s gathering of the cloth upon the cord requires that the cloth should in no instance be stitched to the cord, and the particular disposition of the needle 0 herein disclosed is adapted to always carry the stitching beyond the edge of the cord, (see Fig. 3,) and thus permit the goods to be moved or gathered upon the cord Without difficulty. The presser-foot is shown in Fig. 1 as slightly turned at an angle to a straight line extending from the needle in the direction of the line of feed; but it is obvious that the same result may be obtainedby varying the width of the foot itself.

The tubular guide D may be secured in position in any desired manner; but a very efficient method of accomplishing this result is by means of a slot D formed in the baseplate D and adapted to engage projecting flanges E, extending upward from an adjust-- able plate E. This plate maybe held in position by means of a set-screw E and adj usted through the medium of a slot E beneath said screw, as shown in Fig. 2. This adjustable mounting permits the removal of the tubular guide and its replacement by a difierent size when desired and the further adjustment of the plate E to accommodate any class of work, while the guide and its holding-plate can readily be removed whenever it be desired to use the sewing-machine without such attachment.

It is believed that the operation of the invention will be apparent to those skilled in the art, and it will be seen that in the present structure it is not possible to stitch through the cord, as the needle works ilh mediatel y adjacent to the edge of the funnel, disposing the stitch close to the edge of the cord, so as to conceal the thread in the finished product, as shown in Fig. 6. This structure also permits a movement of the cloth upon the cord for any desired purpose, as before suggested. The guide can also be advantageously used for piping or folds by bringing the cloth to a round fold within the guide and then stitching without the cord or with the cord and afterward removing the cord. It is obvious that to obtain the most advantageous results of this character a tubular tapering guide is essential and that such aguide should be substantially circular at all portions of its length and not flattened. The location of the guide upon the base-plate of the machine prevents all swaying or other motion which occurs in cording devices carried by the presser-foot, and the relative position of the guide, work, and needle are always true and uniform. The disposition of the presser-foot brought close to the needle gives pressure and support to the work on the side opposite to the guide, so that in the present invention the work is positively held and controlled during the stitching action, and the angular disposition of the face of the foot next the guide allows the goods more freedom in emerging from the guide and does not disturb the straight line of travel. The method of attaching the guide to the base-plate is also believed to be particularly advantageous, as it can readily be removed and replaced without the necessity of using a set-screw, and this economizes the cost of construction as well as simplifies the same.

It is obvious that changes may be made in the details of construction and configuration without departing from the spirit of the invention as defined by the appended claims.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a cording attachment, a base-plate provided with a tapering tubular guide located upon its upper face and within the edge thereof and having a longitudinal edge at its lower portion extending parallel with and above the edge of the base-plate; substantially as specified.

2. In a sewing-machine, the combination of a cording attachment comprising a base-plate having on its upper face a tubularguide pro vided with a longitudinal slot, stitch-formin g mechanism including a needle located immediately adjacent to the delivery end of said slot, and a p resser-foot disposed substantially parallel to the delivery end of said slot; substantially as specified.

3. In a sewing-machine, the combination of a cording attachment comprising a base-plate having on its upper face a tubular guide provided with a longitudinal slot, stitch-forming mechanism including a needle and feeding means located immediately adjacent the delivery end of said slot, and a presser-foot located at one side of said needle and havinga face disposed at an angle to the direction of feed from said needle; substantially as specified.

4. A cording attachment for sewing-machines comprising a base-plate having one of its edges curved back upon itself to form a tapering tubular guide within the edge of the base-plate and having a longitudinal edge parallel with and above the bent edge of said base-plate; substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.

GEORGIANA ROBINSON.
