, 1 e Thisinvention relates'to improvements in a combined foot and folder arrangement forisew' ing machines.

The principal object of this inventioncis...lt'o provide al foldenwhich operatesin combination with a special presser foot, both of which'are attached to a sewing machine for the purpose of l forming a binding to be used in outlining button-hole or pocket openings and stitching the binding to the garment material in one operation. y

A further object of this invention is to provide an attachment for a sewing machine which will permit the feeding of a tape and a piece of garment material through the device at one time and to then pass the same beneath and through a special pressure foot. This pressure foot will guide and feed the material during the stitching of the binding to the goods of the garment.

A still further object is to produce a binding which may be split jointly with the garment material to which it is sewed and in such a manner that, if desired after turning, a lining or pocket material may be also attached to portions of the binding in a neat, eiiicient and economical manner.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same:

Fig. 1 is a side elevation of my device, as the same would appear in use,

Fig. 2 is a front elevation of the folder,

Fig. 3 is a cross-sectional View taken on the line 3-3 of Fig. 2, and on an enlarged scale,

Fig. 4. is a diagrammatic showing of the binding, attached to the goods.

Fig. 5 is a cross-sectional view, taken on the line 5 5 of Fig. 4,

Fig. 6 is a cross-sectional view, similar to- Fig.

v5, showing the material and binding cut,

that itforms a piping aroundl the edge of thev opening which produces a neat effect, but at considerable expense as it is a very tedious operation. Consequently, this type of button-hole is not employed on other than expensive garments.

Applicant has devised means for making this type of button-hole by employing a binding comprising a strip of material having a tape centrally positioned thereon, the material being folded over the tape and stitched thereto, the edges of the material upstanding in parallel relation so as to form aps when folded back upon themselves. formed, to the material and on the right side thereof, where the opening is to be made; as, for instance, a button-hole or a pocket opening. The binding and material is now split, thus leaving a portion of the binding on each side of the opening. The binding is now turned through the opening so that it assumes a position on the wrong side of the material, thus completing the forming of the button-hole or pocket opening.

When desired, the upstanding portions which are now underlying the material may be used for the purpose of stitching to the lining, facing, or to a pocket material.

In order to accomplish the above, I provide a bracket 5, which is secured to the head 6, of a sewing machine.

This bracket, in turn, serves to position an arm 1, to which is attached a support 8, that carries the folder A.

This folder comprises an outside shell 9, having a configuration best shown in Figs. 2 and 3 and within'this shell is a tape guide I I. The tape guide II is of tubular formation and of inverted T-shape as shown in Fig. 2 with the leg thereof anchored to the upper ends of the leg of the inverted T-shaped shell 9.

In using this folder, the tape C is fed through the tape guide I I, centrally of the material passing through the folder to form a completed bindmg.

Secured to the presser bar I2, which is carried by the head piece, is a presser foot I3, split as shown at I4, and having tWo upstanding pieces I6, which serve to guide the vertical portion 20, of the material l5, during the stitching operation. This is accomplished by the needles I1,

This binding is stitched, as it is 3 there being one on each side so as to provide a double line of stitching, as shown at I8, the entire stitching to both form the binding and the securing of it to the garment being done in one operation by the two needles.

When the binding thus formed is attached to the material B, as shown in Fig. 4, it is only necessary to cut the material and the binding as shown in Figs. 6 and 7, and to then turn the binding inside out, as shown in Figs. 8 and 9, to produce a completed, bound opening.

It will thus be seen that I have produced a combined foot and folder arrangement for sew-Y ing machines which will accomplish ail the objects above set forth.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of thev same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:

' In a combined cloth folding guide and tape guide attachment for sewing machines, a cloth folding guide comprising a tubular member tapering towards one end, the tubular member being of inverted T-shape in cross section with the legs thereof spaced apart and connected by a iiat top wall at their upper ends, and the tape guide being positioned in said member and being of inverted T-shape and of tapered tubular formation with the leg of the inverted T-shaped tape guide extending longitudinally and anchored to the top wall of the tubular member.

NUN CI BUFARDECI.
