tal vibrations to the former. Either of these modifications of the levers may be applied to the device shown in Figs. 13 and 14.

In all of the forms of the device the end of the lever 13 is slotted at a, in its forward end, to receive a pin projecting from the threadcarrier 12, thus causing the latter to reciprocate.

The vibrating lever 13, in the construction as illustrated in Figs. 1 to 6, is provided with a second slot, 0, which receives a pin projecting from an arm of the threadguide 2, thus causing it to be vibrated in a horizontal As shown in Figs. 7 to 12, however, the modified form of this thread-guide 2 is such as to require a horizontal reciprocating movement, and this is accomplished by means of an arm, 38, slotted at its end to receive a pinprojecting from an arm, 39, attached to the said thread-guide 2, which slides in a channelway, as before described. L

In the modification shown in Figs. 13 and 14, the carrier 12 operates as in the other forms of the device; but the thread-guard 2 has a right-angular movement imparted to it, as follows It is pivoted to the presser-foot, in the construction as illustrated in Figs. 1 to 6, but

has near its center a curved slot, 0, by which it slides upon said pivot, and it is attached at its rear end to the extremity of the threadcarrier by a pivot which slides in a slot, 0,

which construction causes its end which has the eye 8, in passing from the position shown in Fig. 14 to that of Fig. 13,to first move rear ward, or toward the shank 16, and then forward, or in the same direction as the threadcarrier, thus carrying the pattern-thread a right angle to receive a spool of thread. The

tension device shown on Sheet 1 consists of a metal disk, 30, with alternating spurs, which disk is controlled by a screw, 32, and suitable washers, and, as shown in Sheet 2, of a pair of metal disks or plates, 33, between which the thread passes, which plates are held in frictional contact bymeans of a spring, 34,

encircling the spindle .35, and abutting against a screw-nut, 36, the pressure of which spring 34 may be regulated by said screw-nut 36.

Neither of these tension devices is, however, novel in itself, and therefore may have substituted for it any other form of device for producing tension upon the pattern-thread.

The pattern-thread passing from a spool, 37, mounted upon the holder, after being passed around the tension-wheel 30 or between the tension-disks 33, or other suitable tension device, is passed over a hook, 50, on the frame 16, then is threaded through a guide eye or hook, 11, in the lever 13, thence through the guide-eye 8 in the thread-guide 2; but it may pass direct from the spool to the eye or hook 11, though the first-described threading is desirable.

In order to a full understanding of the operation of this embroidering attachment, we must suppose the sewing-needle to have made a stitch in the fabric and to be raised to its highest position. The fabric being fed, the sewing-thread will be stretched through the needle-eye and down to the fabric in an angular position, as in Figs. 1 and 7. The patternthread is then passed from the guide-eye 8 in the thread-guide 2, so as to lie before the stretched sewing-thread, and at a point behind the plane in which the sewing-needle reciprocates. The descent of the needle will then operate to form a stitch and fasten the end of said pattern-thread down onto the fabric, which pattern-thread will thus be drawn between the hook 6 and stripping-arm 5 of the needle rises it vibrates the levers 17 13, the

latter reciprocating the carrier 12 and causing it to traverse from the position shown in Figs. 5, 12,

and 14 to that shown in Figs. 4, 11, and

carrier 12 and lie against the stop 7. As the 13. In this movement of it the hook 6 of the l carrier 12 engages the pattern-thread, and draws the same overor partially around the stop 7, the inider side of the grooved way 42 being cut out, as at3, to form a channel forthe said thread to lie in, beneath the under sur- 1 face of the carrier 12 and the top of the presserfoot 14. The reciprocation of the carrier 12 begins and proceeds with the movements of the lever 13, while the slot 0, in which the driving-pin of the thread-guide 2 enters, permits said carrier to play a distance before motion is communicated to the said thread guide,

this arrangement permitting the hook of the carrier 12 to engage the pattern-thread and carry it beyond the stop 7 and behind the stopbar 1, thus securing it before the guide 2. begins to affect it. When this is accomplished the motion of the thread-guide 2 begins, and its rearward reciprocation draws thepatternthread in that direction while the carrier 12 advances it, these combined movements distending the pattern-thread from its point of attachment to the fabric around the end of stop 7, behind and nearly parallel, with the stopbar 1, and over the hook 6, as in Figs. 2,4, 8, i

11, and 13.

During this movement of the parts the thread has been payed out from the spool to the extent required. The needle-bar 21 has now reached its highestposition, and the feedmovement is imparted to the fabric in the direction of the arrows, and carries that portion of the pattern-thread which is stretched from the hook6 over the work-orifice 4 to the eye 8 in the thread-guide 2 into a plane behind that in which the needle descends.

In order that this position of the patternthread shall be maintained until the needle has passed down before it, the link 10, connecting the driving-lever 17 to the needle-bar, is

formed with an elongated slot where it embefore the said carrier,.so that the thread may braces the needle-screw. This slot providesa lostmotion-that is,- the needle may descend to pass before the pattern-thread and enter the fabric, thus carrying the sewing-thread over the pattern-thread before the lever 17 begins to move to actuate the instrumentalities which manipulate said pattern-thread.

The needle continues to make its downward stroke to draw the sewing-stitch tight as the thread-carrier 12 and thread-guide 2 make their reverse reciprocations. The carrier 12 now operates, by means of its stripping-arm 5, to cast the pattern-thread off from the stopbar 1, and. the guide 2 draws said thread over be in position to be again engaged by said carrier. The superabundant length of pattern-thread which is required by the throw of the carrier 12 and guide 2, which bind it around the needle, is, during the rearward reciprocations of said parts, withdrawn by the movement of the lever 13, through whose eye or hook 11 said thread passes, the said 'lever 13 thus acting as a take-up, which draws the thread from the position shown in Figs; 4, 11, and 13 to that shown in Figs. 5, 12, and 14, where it lies tightly drawn around the needle, thus forming said thread into an ornamental loop, held fast by the sewing-thread. The needle then rises, the instrumentalities which controlithe pattern-thread again reciprocate in the forward direction, the fabric is fed to determine the length of sewing-stitch, and, consequently, of the pattern-loops, and the operation is repeated.

In case of any irregularity in the patternthread, as where worsted and the like is used, an auxiliary take-up may be required to produce a perfect regularity in the work. This take-up may be provided with a spring, as 40, attached to the lever 13, so as to overlie its guide eye or hook 11, and have the patternthread passed through its bent end, as in Fig. 1; or a similar spring, as 41, attached to the frame-work, so that its hooked end shall stand between the spool 37 and the eye 8 of the guide 2 may have'the pattern-thread passed through its bent end, thence under a fixed hook, 29, to the guide eye or hook 11 and 8. Either of these springs will be drawn out of their normal position by the pattern-thread as it is moved forward by the carrier 12 and guide 2, and will, of course, retract and take up the slackened threads when the parts move into the positions shown in Figs. 2 (dotted lines) and 5, thus drawing the thread so as to form a perfect pattern.

In the modified construction shown in Figs. 7 to 14, inclusive, the parts corresponding with similar parts in the construction shown in Figs. 1 to 6, inclusive, are marked with like characters. There is no material change in the structure of the modifications of the device, except in the mode of actuating the thread-guide 2, the same function and prin- .ciple of operation being common to all of the parts in each structure. Though the thread- ,guide 2 is vibrated in two examples of the 'device, and has a right-line reciprocation inan:

other, its guide-eye 8 moves to and from the same points, and manipulates the patternthread in substantially the same manner; and

thoughthe guideeye in the lever 13 is at the front end thereof, in one instance, and in the rear end in another, its function as a guide and take-up are performed in precisely the same manner by both constructions.

In one modification a twist-controller, 9, is supplied to the guide 2, it being a plate pivoted thereto at its rear end, raised in its center,

where it is pierced with a hole to permit the passage of the thread, and bent down at its forward end to bear over the guide-eye 8 with a spring-pressure. Its function is to prevent the twist which is imparted to the patternthread by the manipulation of it by the carrier and guide, and force the same to remain in that part of the pattern-thread which is beyond the guide-eye 8 or sewed to the fabric. This twist-controller may, of course, be applied to any form of the guide 2, and will prevent any accumulation of twist in the patternthread between the guide 2 and the supplyspool which would prevent the perfect operation of the device.
