T0 @ZZ whom it may concern:

Be it known that I, WILLIAM JASPER, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county of New York and State of New York, have invented a new and Improved Sewing-Machine, of which the following is a full, clear, and exact description.

The invention relates particularly to a machine for sewing straw or, other hats, including. a device for securing wire, cords, reeds, or the like by stitches to the hat.

The objects of the invention are primarily to construct the machine as simply as possible and yet to allow for work on hats having a wide brim, so that wire or4 the like or braids or other trimmings may be stitched to the brims not only at the outer edge but at a point at or near the crown, and to provide means whereby a wire or the like may be secured to the hat by a stitch staggered across the wire from one side to the other. This allows uncovered wiresto be secured to the hat, and it avoids the necessity of stitching through a reed, cord, or covered wire.

To these ends the invention resides in certain novel features of structure and relative arrangement of parts which will be fully hereinafter set forth, and pointed out in the claims.

Reference is had Vto the accompanying drawings, which show, as an example, the preferred embodiment of my invention, in which drawings like characters of reference indicate like parts in the several views, and in which- Figure 1 is a perspective of the lower part of the machine, showing the low feed movement, the long stitch-plate or lower arm, and the device for guiding the wire, cord, reed, or the equivalent. Fig. 2 is a sectional plan of the machine on approximately the line 2 2 of Fig. 1. Fig. 3 is a fragmentary front side elevation, showing the cord-carrier, the slide, and the actuating-cam and gear therefor, and Fig. 4 is a detail view showing the action of the cord-carrier and the manner in which the stitch is staggered over the cord.

1() indicates the base of the machine, from which rises the upper arm 11, supporting the take-up and tension devices and the needle and presser-bar operating devices, all of the usual construction and not shown. 12 indicates the link, driven as usual from a cam wise manipulating the hat.

on the main shaft 14 for operating said devices of the upper arm. 15 indicates the presser-bar, 16 the needle-bar, and 17 the feed-dog, all of which are also of the usual construction. Secured to the said shaft 14 is an eccentric 18, imparting movement to a link 19, having adjustable connection with a slotted arm 20. Said arm is fastened to a rock-shaft 21, mounted in suitable bearings on the base 10. Rising from the rock-shaft is an arm 22, the free end of which is connected to a link 23, in turn connected with the feed-dog 17, so as to impart to said dog its characteristic movement. 24 indicates the lower arm or stitch-plate of the machine, which extends unobstructed (see Figs. 1 and 2) from the feed-dog inward to the upper arm 11 of the machine, and which permits the insertion under the presser-bar of the broad brim of a hat, thus allowing work on such brim on all points along the width of the same. The' arm 22 is relatively short, and extends to a point level with or below the stitch-plate 24, so that it does not interfere with inserting the brim of the hat into the same or withdrawing it therefrom or other- It is this elongated stitch-plate and low-feed-dog movement which enables me to operate on hats such as described above, and which constitutes one of the essential principles of my invention.

Fastened to a flat projecting part 10L of the base (see Figs. 2 and 3) is a bracket from which rises an upwardly-extending part 25 and a horizontally-extending part 26, the latter rising sufliciently above the level of the stitch-plate 24 to permit the free insertion of the hat over the stitch-plate and extending outward to a point nearly in line with the stitch-line of the machine. In the vertical part 25 of the bracket a stud-shaft 27 is mounted. This shaft lies horizontally essentially level with the main shaft 14. Carried on the stud-shaft 27 is a gear 28 and cam 2Q, connected to turn together, and the gear is in mesh with a gear 30, attached to and turning with the main shaft 14. Rotary movement of said main shaft therefore imparts rotary movement to the cam 29, and said cam through the medium of a suitable stud-roller 31 imparts reciprocal movement to a slidebar 32, mounted in bearings 33, formed o'n or fastened to the bracket. The slide-bar 32 IOS has a lug 34, fitting loosely in a groove 35, formed in the under side of the horizontal part 26 of the bracket. In this manner the slide-bar is held securely and allowed-no movement other than reciprocal. At 'its outer end the slide-bar carries a cord-guide 36, which projects outward and downward to a point immediately above the level of the stitch-plate and which is formed with two eyes 36a, through which the cord (indicated at a in Fig. 4) is allowed to pass freely. Upon the operation of the machine a reciprocal movement is imparted to the cord-carrier in unison with the movement of the needle'and other stitch-forming devices, and the cord, in addition to its movement through the machine with the goods to which the cord is being fastened, is also given a vibratory movement across the stitch-line, as indicated by the broken lines in Fig. 4, causing the needle 16a (see Fig. 4) to stitch first on one side of the cord and then on the other, thus staggering or whipping the stitch over thecord. It will be observed that this operation is effected without disturbing the normal or usual actionof the needle, the cord itself being turned first to one side and then to the other of the needle, as explained, and 4it will also be obdle to the other in synchronism with the opcarrier comprising a slide connected tothe carrier, a bracket mounting the slide, said bracket being attached to the frame of the ,sewing-machine, a cam sustained by the lbracket and actuating the slide, and gearing for driving the cam from the shaft of the sewing-machine.

2. The combinationwlth a sewing-machine,

of a bracket attached thereto and overhang- `jacent to the inner endof said'lower arm or stitch-plate and extending upwardly and thence-'outwardly over the plane of the stitchplate, a slide mounted on the bracket, a cordcarrier attached to the slide, for the purpose specified, a cam mounted on the bracket and actuating the slide,` and meansl for driving the cam in unison withv the sewing-machine.

1In testimony whereof I havesigned my name to this specification in the presence of two subscribing witnesses.
