JEFREM JANKOWlTGH, OF' NEW YORK, N. Y., ASSIGNOR TO OAKLEY SELLEOK, OF SAME PLACE.
EMBROIDERING ATTACHMENT FOR SEWING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 233,767, dated October 26, 1880.
Application filed June 15, 1880. (ModeL) T 0 all whom it may concern Be it known that I, JEFREM J ANKOWITOH, of New York city, county of New York, State of New York, have invented a new and 1mproved Embroidery Attachment for Sewing- Machines, which is fully set forth in the following specification and accompanying drawings, in which- Figure l is a view of the head of a sewingmachine, showing my improved attachment applied to the pressenbar thereof. Fig. 2 is a horizontal section on line y y of Fig. l, the resser-bar being omitted. Figs. 3 and 4 are similar sections on the lineam of Fig. 1, showing the loop-forming devices at different steps in the formation of a loop; and Fig. 5 is a detached view of the traveler.
The invention consists in an attachment for sewing-machines, by means of which a series of loops may be produced and laid on the surface of fabrics, and secured thereto by the stitching mechanism.
A represents the presser-foot. B is a spiral bar, pivoted at its lower end on pin 0 in the center of the presser-foot A, and at its upper end on apin fitting a socket formed in screw D in the projection F of the bracket H, to which bracket the presscr-foot is attached.
A traveler, l', is clamped upon the needle-bar of the sewing-machine by means of a screw, K, passing through the arms at its slotted rear end, and embraces at its forward end the bar B, within an opening corresponding with the straight part of the bar. Rotation in alternately different directions is thereby imparted to the bar as the traveler slides along it in its reciprocations with the needle-bar.
The curved looper L is secured at the base of the spiral bar B, so as to oscillate in unison with said bar, and the loop-detainer O is pivoted on pin P on presser-foot A. It is a spring which retracts the loop-detainer O, and S is a stop which limits the backward movement of the loop-detainer.
T T T are the guides for the embroidering-thread, and V is a cam formed at the base of the looper L, or at the lower end of the spiral bar B, for the purpose of throwing forward the loop-detainer 0 simultaneously with the advance of looper L.
The action of the parts is as follows: The embroidery-thread is led through the guides T T T in the order named. As the needle of the sewing-machine rises traveler I, embracing the spiral bar B, causes said bar to turn, and thereby carry the looper L toward the needle. The notch on the forward end of this loopercatches the embroidery-thread, as shown in Fig. 3, and carries it forward until it meets the loop-detainer O, which latter is thrown forward, by the action of cam Vupon its heel, into position to engage with the thread carried by the looper. The looper continues its movement forward, and a V-shaped loop is formed in the embroidery-thread, as shown in Fig. 4, around the looper and the loop'deta-iner. When the needle descends the spiral bar B is partially rotated in a reverse direction by the action of traveler I, and retracts the looper. Oam V ceases to act on the end of the loopdetainer, which is retracted by the action of spring R, and the thread-guide T on the traveler I takes up the slack and draws the em broidery-thread taut, the loop remaining upon the loop-detainer, as shown in Fig. 4, until the completion of the stitch which secures it to the fabric, the character of the loop so formed being illustrated in said figure.
What I claim as new, and desire to secure by Letters Patent, is
The combination of the bracket H, adapted to be secured to the presser-bar of a sewingmachine, and the presser-foot A, secured th ereto, with the traveler I, adapted to be connected with the needle-bar of the sewing-machine, the spiral bar B, the looper L, loop-detainer O, and intermediate mechanism whereby the looper and loop-detainer are advanced and retract-ed as said spiral bar is rotated, substantially as described.
