, sewirig-machine, is folded and prepared at the same time that the fold or tuck is being sewed, and with-- out any previous manipulation in folding or marking the goods.

This device may readily be attached to any of the sowing-machincs now in use, and is an improvement upon the invention for which Letters Patent were granted to us, hearing date the 4th day of August, A. 1). 1868, and numbered 80,653.

That others skilled in the art may be able to make and use our invention, we will proceed to describe its construction, and the mode of its operation.

In the drawings a represents a bent arm, very similar in its const-ruction to that shown in Letters Patent No. 80,653, which were granted to us, as already mentioned, except that the arm herein shown is bent in an opposite direction.

This arm, which has the two upright port-ions a and a, with a space, c, between, has a spring, 0', inserted in the space or slot 0, said spring being secured therein by being soldered at the top, or in any other proper .manner.

This spring is shown more fully, as-to its form before it isbent, in fig. T, in which 0'' represents the ears, which serve to guide the work into the slot 0, and 0 represents the two limbs of thespring, which serve to keep the tuck folded as it passes in, and also assists in holding the work in place down upon the cloth-plate of the machine.

The spring, being bent in the middle, is inserted in the slot, and properly secured therein, with the lower edge of the limbs upon the same" plane with the lower side of the bent arm a, and the'ears 0" being bent, as shown mks", in fig. 4, to assist. in giving a free and easy passage to the goods through the slot 0.

The bent arm a has the same shoulder i, against which the edge of the tuck passes, as is shown in the beforementioned Letters Patent, and the spring a, may also be attached in a similar manner.

The piece b has a slot, I), therein, through which passes a thumb-nut, b", securing it to the table or cloth-plate of a machine, and secured to the piece b, by means of the pivot or set-screw f, is an elbow, s, one end of which is bent upward at s".

To this upright end of the said elbow s are pivoted, by means of the set-screw s, or a thumb-nut, the small arms t and t, the other end of the arm it being pivoted to the elevator 11, at 1', while the arm t has a small pin or stud secured thereto, which slides to and fro in the slot 7" made in the elevator-bar 12, whenever the said bar a is raised or depressed.

To the elbow s is secured, by means of a set-screw,

h, or thumb-nut, the bar m, which may be sufficiently thin as to be'somewhat elastic, and a slot, 1, is made therein, so that said bar may be adjusted at about a right angle to, and at any distance from the elevatorbar a, as shown in fig. 3, and the end of said bar in nearest the elevator is turned upward and backward a little, and the end so turned back is made somewhat sharp, so that as a plait which has been sewed passes along over the bar in, back of this sharp edge 0, a slight pressure downward upon the plait will cause the plait to catch against the sharp edge and pass along against it, and thus prevent the goods from being pulled'out of place, toward the elevatorba-r n, and alsoserving as a guide to keep the tuck or plait which is being sewed, always at the same distance from the tuck which has been previously sewed.

presser-foot'l'of [the machine upon which iti The bar m may have any'desirable scale marked groove, inwhich is secured, in any desirable position, the presser-guide (I, by means of a set-s crew, n, or by a thumb-nut.

The fmrm of the presser-guide is shown more fully in fig. (i, in which d is the part which is secured in the groove oi cllannel, and g is the pressing-arm, which may beat nearly right angles with the part d.

The part (1 is curved, as shown in fig. 2, so that the pressing-arm g is brought down to a postion a very little lowerlthan the. .sharp edge 0, upon the bar m.

Another modification of tl'ie'shaip-edged guide 0 is shown in fig. 9, in which is a thin piece of metal, bent so as to clasp the bar m", and may be made to slide to and fro thereon; and to this piece n is zitt-ached the part 0'', which is bent upward slightly above the bar m, and the edge 0 is made sharp, like that upon the bar on. i

There are other and equivalent modes of attaching and arranging the sharp edge to be used in connection with'the tucker, but we prefer that herein shown, as being simple and effective.

The tucker might be operative,-in ameasure, if the spring a were not attached, but we prefer to use it, as it assists greatly in turning the fold of the. tuck over and down upon the cloth-plateof the machine,

- the Florence machine, a small screw is turned down through the presser toot of the machine "into the.

threaded hole e," and it is there perfectly secure, as"? shown in'fig. 1, the 'red lines'represeuting the prsser foot, and the cloth-plate being represented at A.

In attaching the tucker to the various other ma chines in nse, we use variously constructed clamps, one modification of which is shown in fig.'8. This isattached to the'upperside of the lower end of the bent arm a by a screw or thumb-nut passing-through the bole o into the threaded hole 0 in, the arm a,

and the presser-foot passes through the. space 1:, the.

projection a; extendingover a. portion of the'pre'sserfoot, while the partD passes und of the presser-foot. I

The clamp shown inf'fig. S i with the Singer sewing-machine, but the shape of the clamp may be the same for all machines now-in common use, as, it is only necessary that the space or recess 1; s duld be changed in form to suit the l s desired to be used.

The clamp is attached to the presser-fiiot of any machine, with the part nearest the end of the .bent arm a, inwhich is theme'edle-hole c, the point upon the extremity of the part 00 pointing in the same di-' rection as the work moves, as indicated'by the arrows in figs. 1 and 3.

By this means, the tucker may be attached to any of the sewing-machines-in use, by simply varying or changing the form of the clamp-recess c, to conform to the particular construction of the presser-foot to which it is desired to attach the tucker, as the pressr the other. part ers of the diiferent machines vary somewhat in theirf details. v

The bent arm a is bent in either direction accords designed to be. used 'ing as the different machines require the work to be run from right to left, or from left to right.

In those machines which require the work to be run from left to right, as the Wheeler & \Vilson machine, the arm a is bent in an opposite direction to that herein shown, while this is adapted to those machines which take the work in from right to left, as the Florence machine, and various others.

In this connection, we would mention that all sewing-machines now made, we consider as divided into two classes, as regards the movement of-the feed, namely:

First,, th0se in which the space under the needlearm is to the left of the feeder, looking in the direction of the line of motion of. thegoods and second, .those in which said space is to the right of the feeder, looking in the direction of the line of motion of the goods; those in the first case representing the class requiring the work't'o be moved from left to right'with reference to the needle-arm, whilethose in the second case represent the class requiring the work to be moved from right to left.

Having described the construction of our invention, we will now proceed to describe its mode of operation.

The first tuck maybe marked and sewed, as in the ordinary method of making them, or it may be made by this tucker, by gauging by the edge of the cloth if it is convenient to do so.

The cloth is placed upon the elevator-bar n, (fig. 1 representing the whole device attached to a machine,) and the end of the cloth is passed along in the direction of the arrow and in between the ends of the spring 0', the tuck or plait which has just previously been ni'ade being-passed in between the presser-guide .g and the sharp edge 0, and as the presser g presses gently upon the upper surface of the plait, the shg rp edge 0 catches againstthe, edge of the plait under neath, where it has been sewed, and as the goods pass along, the new tuck or plait is being sewed at the same equal relative distance from the last one, said distance being regulated by means of the sharp edge 0 upon the gauge m.

As the fold passes along through the spring 0' and I slot 0, it passes against the oblique edge t" of the; barn, upon one side of the fold, while the other side of the fold passes against the endof the spring a, the arms c of the spring 0 assisting in guiding the fold along properly and in keeping the goods down upon the cloth-plate. I As the fold passes the oblique edge' the fold is pushed over and down uponthe clothplate, one edge of the same'the under one--pas sing along against the shoulder 1", upon the under side of the bent arm a.

The height of the top of the elevator-bar n, above.

the cloth-plate of the machine, regulates the width of the tuck or plait, and to facilitate the adjustment of the elevator-bar to any desirable height, to make a tuck of any certain width, at scale is marked upon the bent arlna, as shown in fig. 2, and as the elevator-bar'is arranged to be always in'a horizontatposition, the cloth passes along upon it more freely than if one end were more elevated than the other, in which case the cloth is apt. to catch, and doesnot pass into the spring 0 freely.

In making very wide tucks or plait-s, either the of the arm,

Having now described our invention, 1 What we claim as new, and desire to secure by Letters Patent, is l I 1. The'spring 0, having the arms 0 and ears 0" thereon, constructed and operating substantially as and for the purposes specified.

2. An elevator, constructed substantially as described, and arranged with the cloth-plate of a sewing-machine, so as to be always in a horizontal position, and adjustable to any desirable height from said cloth-plate, substantially as herein described and set forth.

3. The combination of the bar m, having thesharp edge 0 thereon, with the spring-presser d g, operating substantially as herein described and specified.

4. The combination of the elevator n with the spring 0' and bent arm a, having the guide or shoulder '5 thereon, all operating substantially as herein despecified and described.
