EMBROIDERY ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 250,288, dated November 29, 1881.

Application filed December 23, 1880. (No model.)

, specification.

This embroidery attachment is intended to be applied to either of the two classes of sewing-machines now in most common use viz., that class in which two threads worked by a needle and a shuttle or its equivalent are employed to make the sewing-stitch, and that classic which a single thread inserted through the cloth or other material from one side is enchained on the opposite side to form the sewing-stitch. The embroidery is formed by it with the ordinary needle-thread of the sewingmachine, without the use of an additional or special embroidery-thread, by causing the said needlcthread to be enchained in a series of loops, one within another, consecutively, to form a tambour-stitch on the same side of the material on which it enters, which is the opposite side to that on which the sewing-stitch is formed.

The attachment, which may be secured to the presser-foot of the sewing-machine or to any other suitable support above the work-bed thereof, consists in a hooked embroidery-needle, adapted to work parallel, or nearly so, with the face of the material to be sewed, and having combined with it suitable mechanism whereby it may receive a longitudinal movement back and forth parallel, or thereabout, with the line of the feed of the machine and a lateral movement across the path of the sewing-needle, the two movements being so timed relatively to the ordinary sewing operation of the machine that the hooked embroidery-needle moves forward and to one side of the sewing-needle as the latter ascends, and backward to the other side of said needle as it descends, whereby the sewing-thread is enchained in a series of loops on the upper surface of the fabric.

The hooked needle which I prefer. to use is whatis known as a latch-needle, as that kind of needle provides, by simply closing its latch, for rendering the embroidery attachment inoperative, so that the machine, with the attachment applied, may be used for ordinary sewing without interference or inconvenience. The embroidery attachment may also by that means be thrown into and out of operation at any points in the sewing without breaking or leaving any loose'ends of the thread.

In the accompanyingdrawings,Figuresl and 2 are side views of my attachment, showing its parts in different positions, and representing also the presser-foot, the sewing-needle, and parts of the work-bed, head, needle-bar, and presser-bar of a sewing-machine to which the attachment is applied. Fig. 3 is a plan of the attachment. Figs. 4, 5, 6, 7, 8 are diagrams of portions of the sewing-needle and the embroidery-needle in different positions, illustrating the process of enchaining the loops of the needle-thread. Fig. 9 represents a piece of embroidery-stitching made by my attachment, showing the last two stitches not yet drawn into their place on the face of the cloth.

A is the work-bed of the machine. Bis the presser-foot; and G is the needle-bar, carrying the ordinary sewing-needle, a.

The presser-foot is prolonged beyond the ordinary heel, and in this prolongation is a slideway, 1), arranged parallel with the feed-motion ofthe machine, for the reception of the slide E, which carries the hooked embroidery-needle d. This needle is represented as an ordinary latch-needle. It is firmly secured to a twohorned stock, D, which is pivoted by a pin, 0, to the slide E.

To the slideway b and presser-foot B there is secured a small rigid standard,f, in which is secured the fulcrum-pin g of an elbow-lever, F, one arm of which is received between two upward projections, h h, on the upper face of the slide E, and the other arm of which is slotted to receive a pin, a, which is firmly secured in the needle-bar (J. This pin a may be the screw usually employed to secure the sewingneedle 0 in the needle-bar. The upward-anddownward movement of the needle-bar 0 produces through said lever F a longitudinal movement of the slide E and the attached embroidery-needle d in a direction parallel, or nearly so, with the direction ofthe feed-motion, and by this longitudinal movement of the slide E causes the two horns jj of the embroideryneedle stock D to strike against the front and back of the stationary standard f, and so give the said stock and the attached embroideryneedle d a swinging movement on the pin 6, which carries the said needle across the line of feed and the path of the sewing-needle a. The direction of the feed of the machine using the attachment is from the hooked extremity toward the stock of the embroidery-needle, as

indicated by the arrow in Fig. 3.

When it is not desired to embroider, the latch of the needle dis closed, and the movement of the embroidery-needle will notinterfere with the ordinary sewing operation of the sewingmachine, which will proceed in the usual manher; but when it is desired to embroider, all that is necessary for the operator to do is to open the latch of the embroidery-needle with her finger, after which the operation proceeds as follows: When the sewingneedle has completed its movement into and through the material the embroidery-needle is drawn back to the position shown in dotted outline in Fig. 3, and entirely out of the way of the sewingneedle. As the latter needle rises or makes its retiring movement the embroidery-needle d makes its advance movement, and as these movements are nearly completed the horn j of the stock D strikes the back of the standard f, and socauses the said needle d to move laterally across the path of the sewing-needle and under the point of the latter. The position of the embroidery-needle at the termination of the movements above mentioned is that shown in Fig.4and in bold outline in Fig. 3. In arriving at this position the embroiderynredle bends the sewing-needle thread aside to the right, as shown in Fig. 4. As the sewing-needle makes its descending movement and enters the cloth or material h operated upon the embroidery-needle retires, and theformer carries its thread over the open latch of the latter in the form of aloop, t', and this loop is brought into the hook of the embroidery-needle, as shown in Fig. 5, by the continued retiring movement of the said needle, which, in completing its retiring movement, while the needle completes its descent, is moved laterally to the left by the horn j of its stock D striking the standard f. The positions now occupied by the two needles and the loop are shown in Fig. 6. As the sewing-needle again rises or retires from the cloth the embroidery-needle again advances and moves laterally to the right, and by the time the two needles have again arrived in the position shown in Fig.4 the open latch of the embroidery-needle has passed through the loop 17, as shown in Fig. -7, (which represents the needles in the same position as Fig. 4,) and the thread has been again bent to prepare for the formation of a new loop by the retirement of the embroidery-needle and the entry of the sewingneedle into the cloth. This new loop 1" is shown in Fig. 8, which represents the needles as having again arrived in the positions shown in Fig. 6. While the needles make the lastmentioned movement the first mentioned loop, 0', closes the latch of the embroidery-needle and passes over it, so as to be cast off the said needle, and the said loop has the loop 1" drawn through it and enchained with it, as shown in Fig. 8, the loop 17 being drawn down tight to the face of the cloth by the ordinary operations of tightening the stitch and feeding the cloth in the sewing operation. During the succeeding movements of the needles another new loop is formed and drawn through i, and in this way the operation is repeated, each loop being enchained into its predecessor, and a line of chain or tambour embroidery of any length is formed on the face of the cloth.

To stop the embroidery at any time without stopping the sewing operation, all that is necessary for the operator to do is to close the latch of the embroidery-needle with her finger while the said needle is in the forward position indicated in Figs. 4 and7.

In explaining the operation of my attachment I have not thought it necessary to explain the movement of the shuttle or other device used in combination with the sewing-needle a to make the sewing-stitch, as my attachment in no way changes the ordinary action of such device relatively to that of the sewingneedle; but it may be applied to and operate in any of the ordinary shuttle or rotating hook sewing-machines in use without changing any of the working parts, except taking otf the ordinary presser-foot and putting on the presserfoot B, the parts which constitute the embroidery attachment proper consisting of the presser-foot B, with its standardfand slideway b, the slide E, the hooked needle and its stock D, and the lever F.

What I claim as myinvention, and desire to secure by Letters Patent, is

1. The combination, with the ordinary eyepointed needle ofa sewing-machine, ot'a hooked embroidering-needle arranged on that side of the cloth at which the sewing-needle enters, and mechanism for movingsaid hooked needle forward and to one side of the sewing-needle as the latter ascends and backward and to the other side of said needle asit descends, whereby the sewing-thread is enchained in a series of loops on the upper surface of the fabric, substantially as described.

2. The embroidery attachment comprising the presser-foot B, with attached slideway I), and standard f, the slide E, the hooked needle 01, and its horned stock D, and the lever F, the whole combined for operation with the sewing-needle or" a sewing-machine, substantially as herein described.
