SPECIFICATION To all whom, it may concern:

'Be it known that I, MARGARET CUMMINGS,

ofiJersey City, New J ersey, have invented anew and useful Improvement in Tucker 0r Plaiter Attachments for Sewing-Machines, which invention is fully set forth in the fol-v lowing specification.

' \Vhile many tucker attachments for sewingmaehines have been devised and some put upon the market, theyare little used, particularly such as are adapted to form what may be styled a three-pl y tuck or plai t, wherein the stitches pass through three thicknesses of the goods, and thus better serve to hold the tuck in the desired position, even when the goods are stretched. In the ordinary tuck, wherein the stitches pass only through two thicknesses of the goods, the tucks are easily pulled out of shape and stand up perpendicular to the surface of the fabric when the latter is stretched. The limited use of tuckers heretofore placed upon the market is doubtless due to the more orless complicated structure thereof, the ordinary seamstress being unable to master the manipulation and proper use of the same.

The object of my invention is to provide an efficient tucker attachment of such extreme simplicity that it can be readily employed by any one who is at all familiar with the running of sewing machines and can be manufactured and sold at minimum cost and readily adjusted to the different sewing-machines in common use.

Said invention will be bestunderstood by reference to the accompanying drawings, wherein- Figure l is an elevation of parts of a sewingmachine having my tucker applied thereto. Fig. 2 is an end elevation from the left of Fig. 1. Fig. 3 is a plan View, the head of the machine being shown in section; and Fig. l is a detail perspective of part of the tucker.

1 is the overhanging arm of a sewing-inachine.

2 is the head.

'3 is a needle-bar carrying needle i and reci'procated in the head by an oscillating arm 5,. driven in the usual manner.

6 is the presser-foot bar movable vertically .in head :2 and carrying a prcsse-r-foot'i at its forming part of Letters Patent No. 740,094, dated September 29, 1903. Application filed January 20,1903. Serial No. 139.785. K30 model.)

lower end. In Figs. 1 and 2 the presser-foot is shown in its lowered position.

S is the work-plate'ot the machine.

The parts constituting my improved tucker or plaiter will now be described.

10 is a plate of thin sheet metal having an elongated slot 11 therein through which a clamping screw 12 pas es into a screwthreaded opening in work-plate S, a milled head 13 on the screw bearing upon the plate 10 and tightly securing it in the desired posit-ion of adjustment.

14 is an overhanging lade formed integral with the plate 10 by bending upwardly and over asuitable extension on said plate. The fabric to be tucked or planed is carried around the edge 15- of said blade, as described hereinafter.

is a second plate or blade extending at its free end under the end of blade ll and having therein an elongated s.ot 21. A gcige for determining the distance between tucks or plaits is secured to blade 2). It. consists of a horizontal part 2-3, tearing against the underside of biade '20, and a vertical flange v 23, adapted to bear against the edge of a previously-formed tuck or plait, the two parts being formed together by bending a strip of sheet metal. A screw 3-2, .pmjeeting upwardly through slot '31, is engaged by a milled clamp-nutwhich bears against the top of blade 20 and secures the gage in the desired position of adjustment. The o -Jade and its gage are suspended free of plate In by the following connections: 40 is a bar freely movable in an opening 41, usually provided H1 the heads of sewing-machines for the attachment of auxiliary devices. The bfi! is secured in said opening in the desired position of adjustment by a set-screw m At one end bar AC0 has a right-angled curved and flattened extension in which is an eiongated slet it. A flattened, curredmnd sin iharly-slotted arm is secured to the right-hand end of blade 20. A screw in having a head 32 at one end bearing against arm 54), through the.

slots in said arm and in extension 4.3 and is engaged by a nut 63, which against said extension and clamps the parts together,

thereby affording an adju table connection whereby the Made 20 may 2 supported in distance between tucks, means the desiredposition. As will be understood,

the parts constituting my invention may be readily attached to a sewing-machine and re moved therefrom.

In operation the set-screw i2 is manipulated andrthe rod 40 moved-to secure blade 20 in'the desired position, preferably with its free end extcnrlingaeross and slightly beyond the line of scam, so as to form a three-ply tuck or plait. The gage is adjusted to the position according to the desired distance between tucks. blade 1*. to extend beyond the line of seam a distance corresponding to the width of tuck desired. The fabriefO passes over blade 14, loops around its edge, and then around the edge of and under blade 20 and the gage. As it is advanced toward the needle the presser-foot 7 grips and holds the formed tuck until the stitches have passed therethrough. 'lhevertieal flange 23 of the gage bears against a. previously-formed tuck 71 and determines the distance between tucks.

\Vhat I claim is 1. A tucker orplaiter attachment for sewing-machines eom rising a plate having an overhanging tuck or lait forming blade thereon, means adjustablysecuring said plate to the work-plate thereby determining the width of tuck or plait to bejtormed, a second tuck or plait forming blade-{extending under and cooperating with said overhanging blade to form the tuck or plait, a gagejextendin-g across the underside of the seeol lblade having an uprightflange adapted to beai' iagainstapreviously-formcd tuck or plait tlod termine the iring said gage directly to the second blade irrdiiferent positions of adjustment to vary the distance between tucks, said means consisting of a pin on the gage passing upwardly through an elongated slotin the second blade anda nut Plate 10 is adjusted to cause engaging said pin to secure the parts in theiradjusted position, and connections support ing said second blade and its gage in a suspended position so that the fabric can freely pass thereunder.

f3. Ina tucker or plaiterattachment or sewing-machines, the combination with an overhanging bladc, of a second'blade extending beneath the edge of the overhanging blade,

and means for supporting said sec 'and blade in a suspended position so that the fabric can freely pass thereunder, said means consisting of a horizontal bar secured to a part of the machine above its work-plate and an extensible connection between the horizontal bar and the second blade for varying the dis-- tance between said parts in avertieal direction.

3. In a tucker or plaiter attachment for sewing-machines, the combination with an overhanging blade, of asecond blade extending beneath the edge of the overhanging blade, and means for supporting said second blade in a suspended position so that'the fabric can freely pass thereunder, said means consisting of a horizontal bar adjustably secured to a partof the machine above its work-plate, a slotted angular extension on the horizontal bar, an arm projecting upwardly from the second blade, a screw passing through a hole in the arm and the slot in the extension and engaged by a nut for securely clamping the parts together in the desired position of adjustment.

In testimony whereof I have signed this specification in the presence of two subscrib-' ing witnesses. Y

MARGARET CUMMINGS.
