IMPROVEMENT IN EMBROIDERING ATTACHMENTS FOR SEWING-MACHINS.

.ters of reference marked thereon making a part of this specification.

Figure 1 ofthe drawing is a representation of a top-plan view of my invention; Fig. 2 is a detail view, and Fig. 3 is'a sectional view, of the same. v y

This invention has relation to embroiderin g attachments for sewinganachines; and it consists in the construction and novel arrangement of devices for'alternating the bent le- 1 vers, through the eyes of. which pass, respectively, the bra-id and thread, substantially as and for the purpose hereinafter more fully described.

The accompanying drawing shows an embroiderer designed especially for attachment to aSinger sewing-machine, but with proper modification the apparatus may be adapt-ed to other machines.`

A, in the drawing, represents a plate having a slotted lug, b, which is attachedto the face of the Singer sewing-machine, as herein` after explained. The plate A has flanges, a,

att-he sides, running lengthwise, and about ,two-thirds the length of said plate. x lower ends said flanges are bent inwardly,

At their leaving a space of, say, half an inch between their ends. Through the middle of the plate A, for the length of the flanges a, runs a groove, in which lies a slidingplate, B, bent to a right angle at its upper end, and there provided with a pivoted catch, c, designed to be attached to the needle bar. The catch and arm a are correspondingly notched, as shown at c, to enable` them to be more easily attached to the stud or screw designed to re- The plate B is given a vertical needle-bar. Pivoted to the lower endlof the Vers F F'. c shoulders e comes in contact with the point or A Specification forming part of Letters Patent No. 133,901, dated December 1,0, 1872.

plate B is a V-shaped or triangular block, Z, having project-ing shoulders e. To the .lower end, near one side of the plate A, is pivoted alever, D, having a step-like bend at d, with a large central opening, d', vthrough which passes the pivot holding the alternating levers F F. The lever Fis connected to the lever D above the pivotal point e by means of a pin, el, passing through a slot, e2. The lever F is attached, below said pivotal point, to the lever D by a similar pin and slot, respectively marked e3 et.

'Every rising movement of' the needle-bar causes the lever D to move to one .side or another at the opening d. The levers F F', being connectedV to said lever D near said opening, are consequently alternated to assume the proper positions for the operation of em broidering.

The means whereby said motion is obtained a-re briefly as follows: The upper end of the leverD is b ent over to one side, and holds a beveled stud, D. Now, as the slide B rises, the point of' the triangular block lies against the flange o!l nearest said beveled stud, and thus passes between the stud and the flange, thereby forcing the former toward the middle of' the slide, and thus effecting the requisite movement of` the lever D to alternate the lev- As soon as the outermost of the angleof the stud D the block is swung around on its pivot so as to throw its point toward theopposite flange. The slide then descends with the needle-bar until the base of the block Z, now in an oblique position, enters the space between the two ends of' the flanges a, where it comes in contact with one of said ends, at a point on the opposite'side of' a vertical line through its pivot from its point. By this means the point is forced over against the oppositeflange from the one against which, it lay in the preceding upward movement, and, as the slide ascends, passes between the stud D and Vsaid ange, again forcing said lstud over,'and thus effecting a reverse alternate movement of' the levers F F. The spools I, from which the levers F F are fed, are

held on posts H rising from plates on the levers F F and flanges a, substantially as. ends of a transverse-bar, J,.secnred to the specified. plate A. In testimony that I claim the foregoing I Having thus described my invention, what have hereunto set my hand this 3d day of I claim as new, and desire to secure by Let- September, 1872.
