'lO ALL Wil-QM IT MAY GONCERN: i

Be it known that I, CHARLES H.-GAnDNEn, ofthe city of Rochester, in the State of New York, have invented a new and useful Tucker; and I de hereby declare that the following is afull, clear, andexact description thereof, reference being had'te the accompanying drawing, making part of this specification, in which- Figurel is a top view, in whi'chiare represented two tucks of the fabric in blue lines.

Figure 2 is .a side elevation.

Figure 3 is a transverse section in the direction of themed-lines in figs. 1, 2, and Il.

Figure 4 is an inverted view of the presser-foot plate.

Like letters of reference indicate .corresponding parts.

The nature of this invention will be understood from the drawings and` specifications.

To enable'others skilled in theart to make and use my invention, I will describe its construction and operation.

I make my tucker in two parts, A and B, one of which, A, is attached to the table of a sewing-machine by a clamping-screw at h.

The-part A consists of a plate raised on the outer end, shown at c, the inner edge of which has a channel, c, in half-round conical shape, and on the side next to the needle Gr, gs. 1 and 2'. The upper edge d Iof the channel is made thin, shown in g. 1 in dotted lines, and fig. 2 in full lines.4 On c is a movable guide-plate, H', which regulates the width of the tuck, and itis sustained'in any' desired position between the ribs o by a. set screw, U, passing through the slot ol y The piece B is composed of a slotted `horizontal lplate, IzI, hav-ing a ila'rng raised lip, u, a pai-t, L, serving as a presser, and which is attached to the shank of the presser-bar, and a spring-lip, a, having an 'open-eyed slot.

An adjustable guidinggauge,f, workson the under side ofthe part I3, and is adjustedby means ofthe thumbnut and screw e. The guiding-gaugef is also kept in position by. projections, that work in grooves, K, on'the under side, and an overlapping-lip, y, shown in iig. il. i.

Between the slot q andthe needle Gr, the plateis cut away, as shown in iig. 4, and is eovered'by 'the arch it, shown in each figure.V I also attach a thin spring-plate, a, iig. 4, tol the outer end of the plate VH, in the extreme outer corner of which is formedan open eyelet, c,thro'ugh which the needle passes. On the outer edge of the front end of the guiding-gangef, I form aprojecting liphij, figs. 2 and 4, (indotted lines iig. 1,) ,to sustain the edge of the fabric. l

The object of this invention is to make tucks in dress-materials, and sew them at the time they are being folded.

The operation of this invention is as follows:

In commencing the first tuck, it may be necessary te make a, lineby creasing the materiaher otherwise, tlie guidin'g-gaugefbcing' set the required distanoefrom the place the iirst tuck is to be formed. The operator 'is-,aided in holding the material straight by' keeping the line parallel with the guiding-gauge. As the fabric is bcingfed'into the machine, the conical-shaped channel causes it` toV l.roll over in the form of a Wave, and, being folded around the edge of the adjustable guido II', and under it, and around the outer end ofthe plate H, it passesbetween the spring-platen and presserffoot L in the form of a tuck, and is Stitched at the same time, the opening in the eyelet allowing the formed stitch to pass out as the work is fed along.

The parts A and B are so arranged, when together ori-the machine, that the inner edge of plate H enters the channel, c, of the part A, iig. 2, leaving a space between it and the channel e to 'alloiv the fabric 'to pass.

'lhe spring a keeps the material in a perfect fold after tfpassesv through the conical-shaped channel,v until afterthe needle hasl made the stitch, and the cyelet being open, as shown in the drawings, allows the formed fstitchto passent.4 y

'Ihis arrangement is 'very desirable. as, without some device 'forv sustaining the' material until afterl the 'needle hns'passed through it, the tucks' will ,not be even. l A 4 'What I 'claim as ,my invention, and desire to secure by Letters Patent,vis Y 1. The piece B, constructed as described, and Vconsisting of the parte u II, Spring rt, with open eyelet e, all 'constructed as and for the purposes set forth. r 'i i l 2. In. combination with the abevethe part'A, consisting of the raised blockc and adjustable plaztcvH", all

construetedas described, and operating together forthepurpose setvforth. i
