EDWIN J. OUBLEY, 0F OHIO-AGO, ILLINOIS.

Letters Patent N 103,578, dated May 31, 1870.

" The. Schedule referred to in these Letters Patent and'making of the lame To all whom it may concern Be it known that I, Enwm J. OUBLEY, of m go, .1n the county of Cook. and State of Illinois, have invented a new and useful Embroidering Attachmentfollowing to heal-full, clear, and exact description thereof, which will enableothers skilledin tlie'art to which my invention appertains, to. make and use the same, reference being had vto thc accompanying drawings foriningipart of this specification.

Figure-1 is a front elevation of my improved (lilbroidery-a'ttachment applied to a sewing-machine; Figure 2 isa side elevation in position for use; am

Figure 3.is aperspectivc: view of the samedetached fromfthe'machine.

Similar letters of reference indicate corresponding parts in the several figures of the drawing.

My invention has for its object to provide an emhroidering-attachment for that class of sewing-machines known as shuttle-machines, but equally applicable; to those in which asingle thread is employed. To this end, It. consists in the combination of parts, as will he hereinafter more fully described.

In the accompanying drawings- A is the pres'ser-fo'ot of the machine, attached to the bar B by means of a set-screw, in the usual manner. 7 It is provided with an upright projection in the form of a plate,-G, extending upward outside of the needle-bar, and parallel with the same.

The upper portion of the plate is cut out and slotted, as shown at d, to form the two guide-arms E E. F is the oscillating plate, pivotedcentrally to the inner surface of the projection G between the guidearms, as shown at It.

fig. 1.- I

continues to move down until it slips off H11 are the thread-carrying arms, hung'one over theother to a common pivot, 72, upon the inner surface of theproject-ion G. Their lower ends are bent toward the needle 0' of the machine, and work immediately in front of the same, as will be hereinafter described.

- The upper end of the arm H is pivoted to the oscilIat-ing plate F above the central pivot 1:, and the arm 11 below said pivot in the same line.

The upper ends of both arms are slotted or notched to permit their motion when the plate F is oscillated.

The spools of thread K, to be used for embroidering, are mounted upon arms J, projecting from each side of the plate 0, as shown in fig. 1.

The operation is as follows:

The embroidering thread at is first passed from the spools Kthrough the holes or loops formed in the' lower ends of the arms H H, and the machine set in motion.

L is an arm, attached to the needle-bar N, and bent at rightangles at its lower end, to enter the slot 1 in the plate 0.

As the needle-bar descends, the bent endof the I arm L comes in contact with the top or upper edge of the oscillating plate F, along which it rides, to.

throw the latter into an inclined position, as shown'in Thearm the plate, and catches into one of the notches 0, formed in opposite edges of said plate. I

When the needle-bar rises, the arm L lifts the plate until the notch o is opposite one of the shoulders U, formed in the arms E, as shown, whenfthe arm L releases the plate F, and leaves it, ,iclined in a direction opposite to its first position;

By this arrangement, the plate F is inclined alternatel y in opposite directions, and as the arms H and H" are pivoted thereto, one-above the other, they are causedto-vibrate rapidly across each other, crossing the embroidering threads in front of-the needle at' each vibration. r

, The plate F is out away'upon its-lower edge to form shoulders s, which, as the plate oscillates, strike the pivot, and preventsaidplate' from beingthrown too far to one side. I

The needle of the machine makes'a stitch to secure: the embroidering threads to the goods, at the points of intersection of the latter threads.

The arm L is made elastic, and, when not in operation, occupies a central position within the slot d of. the plate 0. p e

When, however, it is carried down by the needlebar,'it is forced to the side by the'inclination of the plate F, and its elasticity throws it within thenotches 0, when it has cleared the upper surface of said plate.

By this construction, the tendency of the arm is always toward the center of the slot (1, and, therefore, there is no possibility of its failing to enter the notches of theoscillating plate.

A tension-device, R, of suitable construction, is attached to the plate 0 between the spool-arms, for regulating the tension of the embroideririg-threads.

Having thus described my invention,

5 What I claim-as new, and desire to secure by Letter's Patent, is-

The combination with the Presser-foot and its upwardly-projecting plate 0, of the oscillating plate F, having the notches and pins, and the pivoted slotted arms, all constructed as described,andoperated from the needle-bar through the bar L, substantially as herein set forth for the purpose specified.
