MASSACHUSE TS, AssIGNoR TO MAssA- ATTACHMENT FOR BLINDSTITCH"SEWING-MACHINES.

To all whom it may concern: i

' Be it known that I, WOLF ARBETTER, 'a' citizen of the United States, and a resident of Chelsea, in the county of Suffolk and State of Massachusetts, have invented an Improvement inAttachments for Blindstitch Sewing- Machines, of which the following description, in connection With the accompanying draw-. ings, is. aspecification like characters on the drawings representing like parts. Thisinvention has for its object the production of a machine especially devised for felling facings or linings onto waistbarlgdSafter the buttons have been stitched inplace thereon, thus enabling this class of work,,

which has alwaysbeen done by hand, to be done by machinery. v

Figure 1 in front elevation shows asufficient art or a sewing machine, such as illustrate in application, Serial No. 227 ,2'1 8, filed October 5, 1904, with my improvement added to enable my invention to be de-- scribed. Fig.2 isa right-hand side elevation of the parts shown n FigL-lL Fig. 3 is a top or plan view. Fig. 4 is a rear side view of the parts shown inllig. 1, and 5 shows a plan and end view. of the presser-foot detached. v t

In the drawings, A represents part of the framework ofv the machine, it

feed-actuating shaft'Dt, said shaft, the feed cam D thereon, the ieeding device E, pro.-

7 vided witha serrated surface 5, the, reguIa't-'- ing device m for controlling the length of the feed-stroke, and consequently of-t e stitch,

' the stud Efl'embraced by the lower end of the feeding device, the spring m." for lower-- ing and'returning the feeding device to its I starting-position; the needle ai carried bythe arms b n, extended 1 from a needle-carshaft 13'', the com Theoarts herein to be described have been:

devised-to enable facing to be stitched to a waistband automaticallyinstead oi-hv hand,

Specification of Letters'Patent. Application filed March 1,1905. Serial No. 247,836.

as usual The waistband is always provided with buttons, which are attached to the body thereof by hand prior to stitchin the facing the facing to be stitched to the band bile ma;- chine a space must be provided t ough which the r uttons may travel and not interfere wltll the stitching operation, It will be. understood that it is necessary for the -matetdthe waistband, and consequent y to enable rial acted upon by the feed and passing'between the cloth-plate and the presserfoot to 1 be moved in a straight line, anda button could not come between the resser-foot and the Work-su port Without destroyin the op-' eration of t e machine; Instead,-.t erefore,

of the work-support shown'in said appl1ca' tion I have providedawork-support composed of a main plate 200' and an auxiliary 7 7 plate 202, the edges of the plate being so 10- cated with relation one to the other as to re-x' sent a button passage-way or slot 201. he slot 201 is open in the direction of the length of the feed, (preferably shown inrFig; 2,) and the buttons travel below the work-support as' the feeding'device 5, in'engagement with the work, moves the same over the work-sup-V port, ,the'edges of -the main and auxiliary the space between the buttons and waist and in the line ofthe attach; ment of the buttons to said waistband and close to the stitches employed to connect the buttons to the Waistband. 4 p

The work-sup ort sustainsthe waistband at each side the ine in which the buttons are attached thereto. The Work-support has a slot in which moves the serrated upper end 5 v of the feeding device, it engaging the outer side of the waistband near its top edge, or thatpart of the waistb'and above the line of buttons when the-pantaloons are being worn, said edge being guided by contact with'an edge-gage 2'04, (sho wn as occupying its opeffiative position above the'work-su port,) the acting edge of said gage being su stantially 1 "opposite the point where the (hint of the needle enters the inturned'or f0 ded edge w of the waistband or facin w,-which-folded I h by the needle a and stitched" to the waistband b the needlethread and the com lenientarythread device, shown as a loo -ta er containing a bobbincase having a {obbin in which is a second roo 1 thread} all as providedf or in said application .and also in United States Patent N 0. 690,385,

' said shank. The lower end of the shank dated January 7, 1902,. and granted to me.

, The edge=gage is carried at the-up or end,

of a shank 205, provided below sai worksupport with a spring 206, the lower end of the spring being shown as resting on a pin in rests on a gage-controller 207, shown as a lever pivoted at 208 and having a cam-shaped end 209. When the controller stands in the Position shown in the drawings, the gage is fted into its operative position; but when turned into the dotted-line position, Fig. 3,

thespringreferred to retracts the gage into its inoperative position, said gage being then- Withdrawn, so that its top is substantially the facing to Within about an inch or so flush with the work snpport, said gage occupying its ino erative posit-ion when the st itching has been carried along the upper edge of from the front end of the waistband, where the fac- I with the inner edge of the usual buttonhole.

.in'g ends andwhere the line of stitching is to be then carried across the end of the facin and across the'waistband and down paralle iece or fly; Withdrawing the edge-gage, as

escribed, permits the position of the workto be changed shat ly about the needle that the work may be te in a direction at right angles to the direction in which it was being fed when the edge of the Waistband contacted with the edge-gage.

During the stitching of the infolded edge of the material or facing w to the waistbandsaid edge will run against the guiding-edge 2100f the resser-foot, (herein marked D,)

v which differs somewhat from the presser foot ofsaid application. The presser=foothas an overhanging lip 212, provided Witha finger 213,,that is extended forwardly, one side of said finger-forming a continuation of the edge-gage 210-. The resser-f'o'ot has a crossslot 214to receive t sedge-gage 204 when the latter occupies its "operative position above the 'wo'rk-su slot 214 theheel215 of the Presser-foot is provided at its upper side with an inwardlg- "tapering groove 216-, said" oove and t I thrusaent'ering 'fold groove 21-7 in the top of the out part of the resser-foot receiving the curved needle as it approaches the 'material that its point mayenter' the ni'aterial '10 passing under the presser-footbt one thrust, a bender, fully des scribed in said application, being then, raised and at the next t rust, which is a diagonal the edge 10' of the materialw. the Presser-foot has a wing projects (see Fig, 1) beyond the Thebot-tom o 218-, that edge w of the facing from; contact with the material it)", thus enabling the under side of the infold'ed material to travel over said out of contact with the mate rialw" as the material to be stitched is being .overla the in olded edge of the material w down on port. At the rear ofthe 210 far enough to separate the in-.

The rear part of the Presser-foot has a' forwardly-projecting toe 219, that somewhat the end ,of the wing 218 and retains the endof the wing during the action ofthe needle.
