a citizen` of `the United States, and a resident "of Long Island City, borough, and county of Queens, city and State of,` New York, have invented(` certain new and" use` ful Improvements in Methods of Forming Stitches, of which the following is a d`escrip 4 tion in such full7 clear7 and exact (terms as will enable any person `skilled in the art to which it pertains tomake andusethe same.

y My invention relates to amethod of orming; a stitch y on machines for" sewingistraww braid in the manufacture of hats. i i

For a detailed description of my invention reference is now had tothe accompanying drawings which represent the preferred manner of carrying out the same.

In these drawings- Figure 1 is a view showing the work i (straw braid) in section, and illustrating the construction of the stitch, the view also p showing the hook and looperand illustrat-` ing diagrammatically the take-up, tension i and spool and representing the position of the parts which in this specification is termed the starting or first position, and

Figs. 2 to 7 illustrate the six succeeding positions of the stitch forming devices as they occur in the operation of forming the stitch.` i

The hook has a point 10 to pierce the goods and a gap 11 in its front side with overhanging or undercut ends forming a double hook or chock-lile orifice for the reception of the thread so that the thread is held in the hook upon the reciprocation of the same in either direction. The looper has a hill 12 to engage the loop in the thread and also has an eye 13 to receive theJ thread as it passes from the spool, tension and take-up. Exceptingr for these features particularly pointed out the parts named may be of the usual or ordinary construction and the devices for operating such parts and for imparting thereto their characteristic mop p tions may be any of the usual cam, lever and drivin devices which are commonly employed in t is art to operate the stitch iorming devices and which are known to and their application fully understood by `per-- sons skilled in the art. i

The stitch itself is of the chain class with one side nearly blind and isa well known stitch extensively used for years 1n the y tion shown in Fig. 1.

A. description of the operation of my improved stitch` forming.: mechanism lis i as foll (listening Webmestres in the licei- (2) The hook goes down through `the goods and engages thethreadb'which is held inthe eye 13 of the looper. i `(3) The hook goes back up through th goods takingthe thread b through the pre i viously formed loop a and through the goody. forming a second loop 5 and the looper swings back casting oli' from its bill 12 the previously formed loop a. p f

(it) The hook steps Hforward from the poi sition I to II taking the newly formed loop withit.

` (5) The hook againpgoes down through .i the goods taking the newly formed loop b down with itand the looper comes forward to meet the hook and its bill 12 engages the loop 6 and casts said loop oil' from the hook. (6) Thehook then goes'up through the `goods'. making at this time an idle `stroke `slnce no thread is now engaged with the hook.

(7) The empty or idle hook now steps `back from the position II to I and the goods are fed the length ofone stitch whereupon the cycle of operation is completed and the parts again take the iirst position, to wit, that shown in Fig. 1.

It will be observed that in this stitch forming mechanism I have dispensed with one element heretofore commonly employed, namely, `the needle. In fact, the machine sews without a needle, the thread `in its va- `rions parts being controlled by the `hook and looper. Owing to the step forward and back which the hook takes it is allowed toper form; the functions jointly performed by the hook, needle and loopers of the prior stitch forming mechanism of `this class which is illustrated in the above mentioned through the `goods by the action of the hook under the control of the tension, take-up and loo er. A

aving thus described my invention, what I claim es new and desire to secure by Letters Patent of the United Statesisz l. The herein described method of forming a stitch through the-medium of e hook and looper only, the sume consisting in piero ing the goods, cnrryinguthe'` threzt'dl back-tand forth therethrough by temporary ,engagelment only f'saidthread -Withfthe hook, vcasting the'loopfrom thehook-by means permanently carrying saidfthread andifposi- I toning the threadffor' fengagement by the hook :to l formez; succeeding floop L'and finally drawing thef threadfthrough the first loop und through theg'oo'ds.

` fIn testimony f whereof 'I have hereunto signed 'myfnzune in the presence of tW0"W-`it messes.
