PRESSER-FO'OT FOR STRAWV-BRAUID SEWING-MACHINVS.

SPECIFICATION forming part of Letters Patent No. 285,333, dated September 18, 1883.

Application file d April 19,1853. (No model.) Patented in France April 15, 1882.

To all whom, it may4 concern:

My invention relates to improvements upon the straw-braid sewing-machines for which I obtainedLetters Patent of the United States of America, bearing date JuneS, 1880, No. 228,711, and May 2, 1882, No. 257,425; and

. it consistsin a presser-foot having faces on different planes, with a recess in one or'more of said faces for protecting the beaded or fancy edge of the overlapping braids from being crushed between the feeder and presserfoot. t

The improvements are applicable to my aforesaid machines or to other straw-braid machines. Y

Figure 1 of the drawings isa side eleva-tion of part of a machine substantially as .described in my Patent No. 257,425, having the iinproved presser-foot applied thereto. Fig. 2 is a cross-section through the presser-foot, showing the recesses 5 and Figs. 3 and 4 represent modiflcations of the presser-foot.

In the accompanying drawings, the letter a indicates the presser-foot holder, b the lifthandle, c and d the loopers, c the rocking spindle mounted on the lever f, g an adjusting-screw, and h a presser-foot having steps arranged on different planes, all the parts being arranged as described in my aforementioned Patent No. 257,425, to which reference is made for a fuller description of such parts.

When sewing very coarse braids plaited with a fancy edge, orwith what is called a large head77 upon one edge-that is to say, having one edge of the braid considerably thicker than the body of thel same, caused by the straw having been twisted into a braided or fancyn` edge when plaited or otherwise ornamented at the edge-it becomes necessary t0 prevent the presser-foot from pressing upon the said heads or beaded or fancy edges of the braids, as the pressure of the presser-foot upon the braids, when advanced through the machine by the feeder, would crush the heads or beaded or fancy edges of the braids, and thus spoil the appearance of thehat or bonnet when sewed. The presser-foot as ordinarily made is, as is well known, provided with a groove for the passage of the upper braid, the edge of the groove forming also a guide' for the upper braid. This groove, it is obvious, may be made of sufficient depth to receive the whole thickness of the upper braid 5 or it may admit only a part, and thus prevent its beaded or fancy edge from being crushed vduring the operation of sewing. This does not, however, prevent the head of the under or entering braid from crushing by the action ofthe feeder. I therefore provide the presser-foot at its under side with one or more ridges or tongues, e', and with grooves j, making the 'grooves of such depth that vthe presser foot shall not press heavily upon the heads or beaded or fancy edges of the braids. bears upon the body or thin part of the braid, thus protecting the beaded or fancy edge of such braid from pressure, and as the pressure of the feed device t is resisted by the opposite tongue i, the feeder is prevented from compressing the heads of either of the braids. Two or more braids can thus be carried through the machine without the edges being subject to compression.

The tongues t' may be adjustable by means of adjusting-screws s or other suitable devices to adapt the foot to operate on braids of different thicknesses; but for ordinary use I prefer making a series of presser-feet having projections of various depths.

In Fig. 3 the presser-foot is represented with faces in different planes, but having only one recess, the tongue i being extended so as to form one face, and the space outside of the tongue being practically a recess.

Vithout limiting myself to the device shown, and reserving for future applications for Letters Patent such novel features as are not herein claimed,
