SEWING-MACHINE PRESSER-FOOT.

SPECIFICATION forming part of Letters Patent No. 617,075, dated January 3, 1899.

Application filed March 18, 1898. Serial No. 674,822. N motleld To all whom it may concern:

Be it known that I, SAMUEL P. BROWN, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Sewing-Machine Presser-Feet for Laying Tape Preparatory to Stitching; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to sewing-machines, but more particularly has reference to certain improvements in the construction of a presserfoot.

The object of my invention is to enable the presser-foot to properly hold and lay tape on garments such as corsets, so that such tape may be stitched with a two-needle machine.

In order that those skilled in the art to which my invention appertains may more fully understand its construction and operation, I will proceed to describe the same in detail, referring by numbers of reference to the accompanying drawings, which form a part of this application, and in which- Figure 1 is a detail perspective of my improved presser-footg Fig. 2, a longitudinal vertical section of the same; Fig. 3, a perspective illustrating my improvement in the act of laying a tape on a curve, and Figs. 4 and 5 are perspectives showing the manner in which my improvement is utilized for the purpose of laying tape-gores.

Similar numbers of reference denote like parts in the several figures of the drawings.

My improvement has nothing to do with any of the operative parts of a sewing-machine except the presser-foot, and I therefore have not shown such parts; but it will of course be understood that an ordinary two-needle sewingmachine is used and that the needles stitch the tape along the edges thereof.

Heretofore presser-feet have been equipped for laying tape so that the latter might be stitched with a two-needle machine; but none of these prior devices could properly lay the tape when following curved contours, nor could such devices be utilized for laying a gore without leaving an unsightly and twisted bunch of tape at the apex of the gore.

Tape, as is well known, is quite soft and flexible and will readily collapse or bunch together while being laid by the usual presserfoot in a curve; and it is the object of my present invention to so construct the presserfoot that it will properly support and reinforce the tape in the manner Which I will now describe.

1 is an ordinary flat-bottomed presser-foot having needle-holes 2 and capable of ready attachment to the usual presser-bar 3. At the front end of the foot is a gate 45, which is just the width of the tape, the rear wall of this gate being approximately at right angles to the line of feed of the sewing-machine. The front wall of this gate is formed by wings 5, which rise above the plane of the presser-foot and are secured thereto in any ordinary manner. These wings are in close proximity to the rear wall of the gate, so that the tape will be snugly embraced between such wall and wings, and the latter are preferably located only at the ends of the gate and do not ex tend to the middle portion thereof. It is advisable to equip presser-feet of this description with what are termed plow-noses, and I have therefore provided a plow-nose 6, which is extended directly from the wings 5. In the construction shown in the drawings the V shape of theplow leaves a correspondinglyshaped recess, as it were, as the only boundary for the middle portion of the gate 4:, and this is a good thing in some instances where it becomes desirable to make some provision for fullness in the center of the tape owing to the slight drawing together of the edges thereof. Referring to Fig. 3, it will be noted that the tape is firmly backed or reinforced by these wings at a point immediately above the gate 4, so that the tape will be caused to closely hug the inner wall of the gate and not draw together and Wrinkle.

In laying and stitching a tape-gore it is a very simple matter to perform the first half of such operation; but when the presser-foot is lifted and the work drawn around so as to bring the line of feed of the tape at the proper angle the tape will twist and bunch together beneath the foot, and this bunch is usually I Iclaim as new, and desire to secure by Letters stitched down as well as possible, leaving an unsightlylump, which is usually covered with some sort of ornamental trimming in order to conceal it.

In my improvement after the presser-foot is lifted and the work turned around the twist by the slight manipulation of the operator is immediately transferred to that portion of the tape above the presser-foot and between the latter and the tension, as shown at Fig. 5, so that the tape is readily laid and stitched flat and free from all wrinkles, as shown. There are various other advantages that at tach themselves to my improvement, and it can well be said that it is the only presser-foot known which can lay tape properly around a curve or in a gore, and this advantage is due solely to the fact that the tape is steadiedand reinforced at a point immediately above the presser-foot, so that such tape is caused to properly hug the inner wall of the gate through which it passes.

The V-shaped plow-nose 6 leaves the tape unsupported throughout the middle portion, as will be clear from the drawings, and therefore in laying and stitching a tape-gore the twisting of the tape is most readily effected for the reason that there is nothing to bind or closely hug the tape.

Having thus described my invention, what Patent, is

1. A sewing-machine presser-foot for laying tape preparatory to stitching, the same comprising a flat body having a proper opening therethrough for the passage of the tape, the rear wall of said opening being below the front wall thereof, said front wall rising above the rear wall in substantiallyavertical plane and having between its ends a centrally-disposed recess, while the ends of said front wall direct the tape against the rear wall, substan= tially as set forth.

2. A sewing-machine presser-foot for laying tape preparatory to stitching, the same comprising a flat body having a proper open ing therethrough for the passage of the tape, the rear wall of said opening being below the front wall thereof, said front wall being formed by V-shaped wings which rise above the rear wall in substantially a vertical plane and whose ends back the tape against said rear wall, while no support whatever is afforded by said wings to the middle portion of said tape, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
