Letters Patent No. 93,480, dated August 10,1869.

IMPROVEMENT IN EMBRQIDItEIdING-ATTACHMENT IOR SEWING-MACHINES.

The Schedule referred, trim these Letters Patent and making part of the same l r To all whom it may concern i 1 Be it known that I, ISRAEL M. FItosn, of West Hampton, in the county of Suffolk, and State of New York, have invented anew and improved l lnrbroidering-Attachment to Sewing-Machines; and I do hereby declare that the following is a. full, clean, and. exact description thereof, which will enable o'tiieis' skilled in the art to make and. use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figures 1. and 2 represent side views of my improved embroidering-attachmcnt to sewingunaohinesi Figure 3 is a View of the opposite side of the same. Figures 4 and 5 are plan views of the same, showing the partsjn difl'erent positions.

Figure 6 is a plan view of a piece of fabric embroidered by means of my improved attachment.

Similar letters of reference indicate corresponding parts. v

This invention-relates to a new dcvicagwhich may be attached to any kind of sewing-machine,and which will produce an embroidery-stitch of very fin'e and ornamental appearance.

The invention consists of a swinging bar, which is operated by the needle-bar of the machine, and which imparts oscillating motion to a ring that carries a hook, by which the einbroidery-tln'ead is so placed. that it can be fastened to the fabric by the needle-thread in the desired position.

A, in the drawing, represents the needle-arm of 2. Wheeler 86 Wilson, or other suitable sewing-machine. i i 1 B is the presSer-fbot of the same.

s l This presserdoot 1S perforated, and has a; rim, a,

around the circular aperture 6, as shown.

C is an annular pinion or plate, fitted loosely around the ledge. 11., and carrying a hook, c, on its upper face,

as shown. i

On one side of the aperture 1) the ledge a projects above the pinion. i

The vertical arm I) of the presser-foot is attached to the stationary part of the sewing-machine, in any suitable manner.

To it is pivoted, by a pin, a, an L-shaped plate, E, which carries, at its lower end, a toothed another segment, (1, while its upper arm is in a diiorii aontal position, as shown. 5 l i f l The plate E is pivoted near its centrefand its arms are so placed that they will be in the way ofthe threadguide 1*, or any other projection of the needle-arm, during the up-and-down motion of thesame.

The plate it will thus receive vibratingmotion, being swung up during the upward stroke, anddown during the downward stroke of the needle-mind By this vibrating motion of the plate E and segment d, oscillating motion is imparted to.the pinion 0,. ll

' row 2.

The embroidering-thread f is passed from a suitable bobbin through the thread-guide F, through the vertical arm of the prcsser-foot, through the front end of the segment d, through .a guide, c, secured to the presscr-foot, and through the aperture 1) t0 the fabric, which is fed in the direction of the arrow 1, fig. 5, in the usual or suitable manner.

The operation is as follows:

When the end of the embroidering-thread has been fastened to the fabric, and whenthe needle is fitted through the fabric, the parts are all in the position shown in figs. 1, 3, and 5, that is to say, the hook c is in front of the aperture 1).

The needlethread g projects from the fabric through the aperture 7), and on the right-hand side of the thread f.

As the needle-armswings up, the pinion is turned, so that the hook 0 travels in the direction of the ar- The book will thereby be caused to carry the thread j around the projecting part of the ledge a, so that it will he as indicated in fig; 4, that is to say, it will form a loop, of which one straight side passes diametrioally across the upper end of the rim or, while its round part will, in a semicircular form, fit around half the rim a, the inner end being fastencdto the fabric.

During the next downward stroke of the needle, the thread g will be carried down through said loop, over the straight diametrical part of the same, and will thereby take the loop of! the rim a, and fasten it upon the fabric, seas to leave one part of it still free.

Fig. 6 clearly represents the form of loops and arrangement of threads.

Each stitch of the needle-thread connects two loops of the embroidering-thread, and the needle-thread itself is 'or may be fastened under the fabric by means of a straight shuttle-thread, h, shown in fig. 3.

I claim as new, and desire to secure by Letters Patent- 1. The embroidery-attachment to sewing-machines, when composed of the vibrating arm E, oscillating pinion 0, book 0, and rim a, all arranged in connec tion with the resser-foot, or its equivalent, substantially as described, and operating as set forth.

2. The combination of the swinging plate E with the reciprocating needle-carrier, the former being arran ged'with reference to the latter, and being operated thereby, substantially in the manner specified, to vibrate, directly or indirectly, an annular ring, pinion, or hub, provided-with a hook thereon, as set forth.
