T 0 'aZZw/wm it may concern:

Be it known that LIALBERT H. Dn Von,

a citizen of the United States, residing at VVestfield, in the county of Union and State of New Jersey, have invented certain new "and useful Improvements in Attachments I It aims to provide a new and improved combination and arrangement of attach ments for making'an ornamental facing for body garments of the character shown in my prior Patent No. 1,239,675,-granted September 11, 1917, on a combined ruining and The exact-Y ornamental stitching machine. ing demands ofthe trade necessitate precision and uniformity productionand the present invention answers these requirements. W

The invention comprises a strip-folder, supported from beneath the c1othplate of a sewing machine and inclined upwardly toward its delivery end which is located in front of the feed-do'gs, a lace-guide, supported by the strip-folder andbetween the same and the cloth-plate, a pivoted laceconductor, leading a strip of lace-or ed ing to the line of "feed at] substantially right angles and then reversing it into parallelism with the line of .feed before the lace or edg-' ing enters thelace-guide, and a stripping plate, having an upright edge guiding wall for directing a knit body-fabric into abutting relation; with the lace :or edging, allof the above mentioned features being located in advance of a combined ruflling and ornamental stitching machine for concealing the abutting edges of the knit body fabric and lace with a covering-thread of an'attractive color in a figure 8 pattern and for simultaneously stitching both the fabric and lace to a reinforcing facing. strip whose raw,

edges are infolded' The knit body fabric is'difl'erentially fed to the stitching point by the ruflling blade to make the stitched article smooth and'flat and to prevent it from being drawn or puckered. a

An embodiment of the invention is illustrated in the accompanying drawings in which Figure lis a plan view of, the invenvention applied to a machine, parts below, the cloth-plate being exposed by fracturing the latter. Fig. 2 is a front-elevation of the lat-' tachment .withthe ,cloth plate appearing in'sectionQ Fig. 3 is a side elevation of the same with the cloth-plate appearing in sect on. Fig. tis a side elevation of the stitch forming and rufliing instrume'ntalities above the cloth-plate; Fig. 5 is a cross-section of the work done with this attachment, and Fig. 6 1s a perspective view of the bracket for supporting the lace-conductor.

The invention is shown applied to a combined rufillng and ornamental stitching machine having a ruffling blade 1 secured to an attachment arm 2supported in a'bearing of a pivoted hanger 4 and rocked through alevenarm 5 in a manner full in my pending application erial No. 132,521, filed November 21, 1916, and also havinga looping finger 9 mounted and oper ated substantially as disclosed in my pend-- ing application Serial No. 147,295, filedv vided with a removable section 15 cut away to form an opening 16, one side of which a. pears in Fig.4; a A stripping plate 17 having an edge-guiding wall 18,,isadjustably secured over the opening 16. Ashank19 extendin laterally from thestripping plate is slotte M20 and securedby a clamp-screw 21 to an arm 22 which is pivoted by screws 23 to the removable section15 ofthe cloth-plate from which rises a stop-pin 23' for-locating the working position of the stripping plate.

The above mentioned constructionis all located above thecloth-plate, what follows is largely below. p Y

With its upper surface substantially flush with the cloth-plate is a lace-guide 24 hav ing an edge-guiding Wall 25, an overhanging lip 26 and a depending and lateral support ing flange which is slotted at 27 for the screws 28 adjustably securing the guide to a plate 29 projecting from one side of a stripfolder 30 to which it is soldered or otherwisesuitably secured; The strip-folder 30 disclosed has the usual edge-folding scrolls or chan-' nels 31 audits rectangularbase-plate 32 is movablymounted in a dovetailed slideway 33 provided in a supporting plate 34 screwed.

h the cloth-aplat'e l4.

inclined upwardly from its receiving'to its delivcry end which is located substantially..'

, toa rod 36 which is adjustably clamped by.

38- depending from the screws 37 in a big e strip-folder is in a plane with and slightly behind'the del-ivery end ofthe lace-"guide 24 which, it will be remembered-,'is flush or nearly so with the porting plate34 below the slideway 33 frictionally retains the strip-folder and laceguide In working position which position" is determined-by the stoprpin' 4O depending from the base-plate 32 to which the strip folderis fixedly secured.-

A Z bracket 41,- having an lateralarm 42 in which is threaded-astud-screw 43, pivot ally supports a lace-conductor 44 and a v spring-catch 45 beneath the arm 42 retains the lace-conductor in normal working position' underneath the cloth-plate during the 1 operation of the machine while a friction washer- 46 "at all times steadies the conduc-' tor 44 against'too free movement; "The laceconductor extendspreferably at right angles or'substantially so to the line of feed and itsfree end 47 is bent upwardly and over at an angle into approximately parallelis m with thel lineof' feedq Mounted on the lace T conductor 44 at its r receiving end 0 is a guide-eye 48,- intermediateits ends'is an adjustable tension device 49' ofthe plural rod type, andi'at itsfree end 47 is an adjustable close'drguizder-loop 50; In the bent reversing I from view as well as lend an attractive apwall 51 of the lace-conductor'isprovided an opening 52 for confining the lace durin its reversal and-through a slot 53 communicating therewith the lace may be readily introneedles; coveringkthread" '57, of awfsuitable pleasing color, preferably in a figure 8 pat tern, is laid'to v conceal the. abutting'edges pearancetozthe product. Preferably a facingstrip 58, of woven or other suitable ma-= teriahis secured to the work with one side underlying the meeting edges of the bodygarment and lace and with :itsother side secured by the seam 59 of the needle 11 to the knit body fabric. The raw edge of the knit body fabric is thus secured against" ravelingwithout foldingit into a bulky -ridge, th e meeting edges of the fabric and, lace are also effectively concealed from View,

and the lace and facing strip may be led to the work withoutrequiring attention from the operator during the operation of the machine.
