seating achines, adapted to cooperate with i an tau. ary feeding mechanism, "such as shown nd described in an application torpatent, Serial lxo. 222,795 filed by lames R. Moi itt August Bl, 1904:. The or y point of tion between this n t-echanism and 'cferrcd to, that: the auxiliary lingghladc is extended laterally across the space between and in front of the two needles and the blade acts across the face of the goods between theueedles, to lay the elastic knitted fabric flat, and without wi inkles or distortion, as would be the case were not. an auxiliary feeding device employed to overcome the draw of the fabric incident to its beinlgi guided by the operatm', folding dci ice, etc. In connection with this mechanism, [if employ a folding guide to guide and fold in advance of the sewing operation, two pieces of fabric. the top piece of which-isfknitted or elastic fabric. and which is operated upon by the auxiliary feed, and hasionfe of its edges folded downward and inward upon the second fabric. 'lhe second piece of; fabric has both its edges folded upward and inward against the top piece of fabric, one of the needles passing through the folded edge of the top and bottom fabric, and the opposite needle passing through one thickhess of the body fabric, and through thfolded portion of the bottom piece, to

45 to n the button hole strip upon the front of a knitted skirt.

, The invention consists in the matters hereinafter described and referred to in the appended claims.

The invention is illustrated in the accompanying drawings, in which,

Fig. 8 is a view of the delivery end of the guide showing the fabric. il'iereii r.

g In these drawings, the feeding device or blade it iscarried on the lower end of an arm 2, which is adjustably attached to the lin'aekct 3, clamped on the lower end of the bar or rod 4, which is pivoted on a plate 5, attached to the head of the machine, and connected to the needle 'bar by means of the connection (3, so that in the upward movement of the needle bar, the feeding device The guide used with the machine is provided with a suitable base A, upon which is attached by a suitable screw, (1, the scroll ll, to fold downwardly and inwardly the L edge of the top pieceof material 10 it having a forwardly projecting arm Clo keep the folded edge properly directed to the right hand needle. The lower folding guide l) is provided with a tongue E, as shown in Fig. 5 to properly guide. and 'fold a strip of material 11, turning upwardly and inwardly both edges thereof. 'lhe'outer edge of the fold in the strip is substantiallybelow the outer edge of the fold in the body piece of material, although in practice it. is sometimes desirable to have the bottom right hand inwardlyand upwardly turned edge slightly inside the edge of the top folded edge, as shown in Fig. 7, in order that the strip or facing material may be concealed 5 from view when the garment is exposed for sale.

The lower folding guide is provided with a slot F, for the puraose of thrcadin the strip through the gui e. The upper folding guide Bis mounted above the lower foldmg guide D, and has its delivery end 0 in front of the delivery end of the lower guide, thus forn'iing a space for the operation of the auxiliary feeder. The presser foot G, is provided with an auxiliary bearing surface of, on tne side under which passes the increased thickness of material. This is neces sary in a machine of this kind to hold the fabric in proper position upon the main feed dog to feed both sides of the seam evenly.

The operation of my device Will be obvious. The strip of material 11 is led through the opening K in the guide D underneath the tongue E. The guide D tapers toward itsv forward end, and, therefore, as the strip approaches the forward end of the guide, itwill be folded up over the edges of the tongue E on to the upper surface thereof, as clearlyshowli in Fig. 8. The tongue E is spaced from the sides of the guide D, and tlms forms a guiding recess or passage at -ach side of the uide D, which causes the folding above referred to. The tongue E pressesthc strip against the bottom portion of the guide, and places, therefore, a slight tension thereon. The top piece of material is led into the scroll B over the supporting ledge L. Said scroll B has a folding recess 13, which turns the edge of the material underneath the body portion thereof. As clearly shown in Fig. 8, the folded edge of the top piece of material is positioned substantially over the folded edge of the strip, and as the strip and folded top piece of material pass to the stitching mechanism, they will be stitched together, as shown in, Figs. (3 and 7.

Having thus described my invention, what I claim as new and desire to secure by Lettors latent, is--- 1. In a two needle machine, a work support, stitchforming mechanism including two needles, a main feeding device, an auX- iliary feeding device located and operating above said work support, a guiding'n'ien'iber having folding recesses at each of its side edges, a guiding member located above said first named guiding member and having a folding recess at one side thereof, the folding recess in the upper guiding member being substantially .over one of the folding recesses in the lower guiding member and cooperating thcrowith to direct the folded edges of the material in a line adjacent. one of said needles; substmitially as dcscrila'd.

2. in a two needle machine, a work support, stitch-forming mechanism including two needles, a main feeding device, an auxiliary feeding device located and operating above said'work support, a guiding member l'iavmg folding recesses at each of its side edges, a guiding member located above said first named guniling member and having a folding recess at one side thereof, thefolding recess in the'u 'mer guiding member being substantially over one of the folding recesses in the lower guiding member, and

codpeiating therewith, to direct the folded edges of the material in a line adjacent. one

of said needles, said guiding members being adjust-ably attached to the work support; substantially as described.
