Specification of Letters Patent.

Application filed September 5, 1905. Serial No. 277122.

To all whom it may concern.-

Be it known that I, J onN E. STRONG, a citi- Zen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Sewing-Machine Attachments, of which the following is a specification.

My invention relates to improvements in tucking attachments for sewing machines, and its object is toprovide an. attachment with which a flounce, upon a dress skirt, &c., may be tucked on both sides of the seam fold and the folded edges of each, the flounce and the connecting dress skirt fabric, may be wholly enclosed. within the fold of the other connecting fabric and stitched with a single needle and. at a single operation so that the edge, both of the flounce and of the skirt will be wholly covered from view. I attain this object by the mechanism illustrated in the accompanying drawing, in which Figure 1 is a plan of the blank from which the attachment is made; Fig. 2 is a perspective looking at the backend of the attachment; Fig. 3 is an elevation of the attachment looking at its front end; Fig. 4 is an enlarged back end elevation of the attachment showing the position of the fabric in dotted lines, and Fig. 5 is a side elevation of the at tachment shown upon a sectional elevation of the machine bed.

Similar letters refer to similar parts throughout the several views.

In the construction of this attachment I form a blank of thin sheet metal, substantially of the form shown in Fig. 1, having the several wings A, B and. C, B being divided from A by a closely out line, as as, so that the blank can be bent at c, c to form. the bow c, the short projecting end E of which diverges to the point d, as shown by the dotted lines in Figs. 2 and 4, connecting with and forming the wing C. The plate is then bent at I), b, in the opposite direction, forming the bow b, and again at a, a forming the bow a, whence the wing A extends out, practically, parallel with the surface of the machine bed K, and the attachment is secured at a to the end of the retaining bar D, by means of which the attachment is secured to the machine bed, in the usual manner, by thumb screw or other available device. The wing B, by reason of the dividing line 91:, stands normally in substantially the position indicated in Figs. 2, 3 and 4, and the wing C is bent on the line (1, d to form the bow d, so arranged that C will stand over the wing B, forming an opening between the two for the fabric, indicated by the dotted lines e, from which the flounce is to be made, to pass between and thence around through the opening between the bows d and b with the extreme edge in the bow c, forming the line of travel of the flounce. To complete the seam between the skirt and the flounce, the fabric from. which the skirt is to be made, represented by the dotted lines (2, passes between the pro jecting end E and the wing A, and, thence, around the how 0 with the extreme edge in the bow b so that with a line of stitching upon the line of the needle J the flounce will be securely stitched to the dress skirt and the extreme edges of both will be wholly hid fi'om view and inaccessible.

In order'to form a perfect line of tucking upon the folded edge of the flounce it is necessary to provide an auxiliary feed mechanism and this should work upon both sides of the tube E, and for this purpose I construct a feed consisting to two thin plates F, F, pivoted to a head H, as at j, f, so that the free ends bear upon each side of the tube, as indicated in Fig. 5, being held to normal position by a suitable spring, as g. This feed mechanism is actuated by the needle head shaft through the medium of the counter shaft I and the arm G, exactly as all auxiliary feed mechanism connected with sewing machine attachments, are connected, so that as the plates F F are made to reciprocate, as indicated by the dotted lines of the arm G, and said plates, the fabric, shown by the dotted lines at e in Fig. 5, will be made to form slight puffs, as indicated by the dotted lines- 0 which, when passed under the machine shoe, not here shown, .and stitched, will form the desired tucking of the edge of the fiounce at the line of juncture with the dress skirt.

L represents the machine feed plate which feeds the entire fabric, both of the dress skirt and the flounce, after the flounce has been properly tucked and passes under the shoe, which stands directly over this feed plate, though I do not deem it necessary to show it in this connection as it forms no part of my invention, and its oflice and application is perfectly known by every user of sewing machines.

The feed plates F F carry the ruffled fabric to the extreme end of the tube where it is pierced by the descending needle before the receding motion of the feed plates is com- I and C With a loop E forming a channel for the menoed, thus averting the possibility of unfabric e to the point e, and a Wing A and loop ruffling the goods by the return movement of 1 E forming a channel for the fabric 6 to the the feed plates, and the fabric is held to place point I), an auxiliary feed acting upon both by a pressure foot and the feed plate does not sides of the loop E feeding the fabric 8 indemove to carry the fabric forward until the pendent of the fabric e, a slow regular feed needle is Withdrawn and the stitch is per for carrying both the fabrics, and means for fectly formed through the ruffied fabric stitching both fabrics and enclosing both which averts the possibility of unruffling the edges thereof, substantially as stated. fabric e by the receding motion of the feed Signed at Grand Rapids Michigan August plate L. 23, 1905,
