To aZZ whom it may concern..-

Beitknown that LALEXANDERLAUBSOHER,

a citizen of the United States, residing at Bridgeport,in the county ofFairfield and State of Connecticut, have invented certain new and useful Improvements in Plaiters; 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 :0 it appertains to make and use the same.

My invention relates to the manufacture of plaiters, and has for its general objects to simplify and cheapen their construction, and at the same time to greatly improve their mode I 5 of operation in use. V

W'ith these ends in view I have devised the simple and novelconstruction of which the following description, in connection with the accompanying drawings, is a specification,

numbers being used to denote the several parts. I

Figure 1 is a plan View of a portion of the bed of the machine, showing my improved plaitcr in operative position thereon, the needle and presser-foot bar being in section, the

retracted position of the folding-gage being shown in dotted lines; Fig. 2, a front elevation, the needle and presser-foot 'b'ar being raised and the folding gage in the retracted posit'ion; Fig. 3, a similar view, the folding-gage being --in the operative position and .the 'presser-foot down; Fig. 4-, an end elevation illustrating the stitching mechanism, the bed,

throat-plate, and certainop'erative parts of the 5 machine, the plate of the attachment being in section, Fig. 5, an inverted perspective of the presser-fo'ot detached, and Fig. 6 is a perspectiveof the throat-plate detached.

1 denotes the bed ofthe machine; 2,the feed-point; 3, the needle; 4, the presser-foot bar; 5, the presser-foot; G, the slides,"and 7 the throat-plate. i j

It will of course be understood-that myini: proved plaiter is applicable to all makes and of sewing-machines. lie the present instance I have illustrated it in connection with thestltch lorniing mechanism of a'Wheeler Wilson No.12 sewing-machine, .lshall omit,

however, all description of the stitch-forniing o mechanism, as that :lbrms-no portion of my in vention, with the exception that l have-made changes in the shape of the throat-plate, presser-foot, and feed-point. These changes do not affect the operation of the machine upon ordinary work and have special relation to the working of my improved plaiter. They will presently be described at length.

8 denotes the base-plate of the attachment, which I ordinarily secure to the throat-plate by screws 9. Plate 8 extends outward iron; the bed of the machine, as clearly shown, and

10 of folding-gage 11.. part 10' of shank 10 isa slot, 12. A guide screw, 13, passes through this slot and through the plate andis seenreddW-anniroa the under side. A springwasher, 14;, hearing against the surface of' the shank, provides suliicient friction to hold the shank firmly-in position, but at the sametiine will permit it to slice in or out freely; A guide-pin, 13', on the under side of the shank, passes through a slot, 15, in the plate to prevent lateral movement of the shank and folding-gage.

At the outer end of the shank is a shoulder, 16, which is adapted to engage an adj nstablc stop,- 17, secured to the plate 8., The forward end of the part 10 of the shank 10 is prefen ably beveled, as shown, so as to serveas an in 8, by which the width of the plaits is regulated? Suppose that the greatest width. of plait is desired,the said beveled. edge is pushed to the last gage-mark to the right on the scale. If a narrower plait is desired, said is pushed to such mark toward the left as will produce the width desired. Having adjusted the folding-gage, stop 17 is locked in position against shoulder-iii by set-screw it. will the foldinggage extends forward from the plate and then inward toward the machine. The shape of the shank, however, is not an essential feature of my invention.

cated by 11, maybe niadc inlic shank; but as it is necessarily made i. erably make it in a separate plow to the shank, as clearly shown.

20 denotes the stitching or S lttlll dex to the graduated scale 18 upon the plate 1 be'noticed in the drawings that the shank of The folding-gage proper, which I, have indi to the outer end thereof is secured the shank At the outer end of the 'the recess of said pr'esser-ioot and having a shank attached to said block, the adjustable spacing-gage 22, also having a shank attached to said block, a plaitet' base-plate, as 8, and a.

5 slidiug foldinggagesupperted by said basepiate to eo-operate with the said stitehing and spacing gages.

5, The combihat-ie'n; with block 25, having means for attachment to a sewing-machine 1'0 presser-fenit-and thesbitehiugand spacing gages carried thereby, of a plate, '8, having a grmi- Hated scale, 18, a sliding foldinggage carried by said plate, and aspring-washer bearing upon the surface of said gage.

In testimony whereof I affix my signature in 10 presence of two witnesses.
