.c My present invention has referenceto an attachment for sewing machines and, h'asifor itsobject thejprovision of, means whereby a binding tape can be 'ac'curatelyfed from a suitable rolland -elfectively stitched: by the edges of a fabric, regardless of theirjreguc larities; of, such edges; and in a manner most convenient to the operator of sew-ing machine. i Y

A further'object is the provision of a binding-feeder. attachment for sewing machines,

which includes a'bracket to be removably attached to the arm of the head of the machine andwhich has journaled on its outer end a a tape carrying spool or roll, friction means 7 2 being provided for preventing the free turn ing of the roll or'spool, swingableand vertically adjustable means being carried by the bracket for a guide through which-the binding tape is fed, in aiinanner to permit ,3 of the saidtape being fold ed upon itself 1 andarranged'over the edges of the fabric on which ,it is stitched by "themachine.

To the attainment of the foregoing and other objects which will present themselves as the nature of the invention is better understood, the improvement also resides in certain other novel features of construction,

combination and operative association of parts, one satisfactoryembodiment of which is disclosed by the accompanying drawings. In the drawings, I Figure 1 is a perspective view of'my improvement in applied position. 5' Figure 2 isa side elevation of the improvement. j 1 r V v v Figure 3 is a top plan view thereof.

Figure 4 is an edge view thereof. J I Figure 5 is a sectional view through the a -011 or spool to illustrate the r'nanner by hubs l0", o t e s i P D Se t-i n't", 1-

which it is remov ably secured on gitsf supporting shaft. 7 1

Figure 6 is a perspective view of one ofthe spools or cores on which the tape is wound.

' Referringnow to the idrawingsin detail the numerall design-ates the table of an ordin'a'ry sewing machine, 2 the head thereof,

3 the presser foot, 4 the needle carrying bar.

,On the horizontal portion or arm 50f the head 2 I arrange the bifurcated or jaw end i of a bar 6.- The clamp orlbar "6 has its'jaw end'provided with an innerfacing ofrcompresslble material sojasnot to infllct ln u'ry to the head of the machine, andtheiuppjer arm of the jaw has, threaded therethrougha binding bolt 7 whereby tov effectively-sustain the clamp on the arm 5 off 'thei head 2.

If desired there may be arranged inthej-aw end of the clamp a spring member onfwhich the compressible facing is arranged: The clamp has an angle ,outer end6'.

Screwed'through the outer end 6 of the clamp there is the threaded portion-ofaa' shaft 8. Screwed on the shaft, andcontact ing with the end 6 of theclamp there is a 3 combined j amb nut and washerS; :The shaft 8 hasits outer endprovided'with a continuous groove 9 that is designed to receive therein a pivotally supported spring-latch 11 carried by the outer member or flange of the spool 10. The spool 10 comprises two memhers,- eachchavingan inner huh Portion: 10

through which-theshaft 8, passes; Opposite" lugs aredesigned to be received innotches 26 on the ends of the spool orv core. 27 on i vhichthe tapeis wound. Usually the tape the j amb nut 8 on the shaft, permits of the arrangement of different sized cores 27 between the elements constitutingth'e: spool 10. Of course, the outer element of the-[spool is removed before the co'r'ecis arranged en the the hub'the inner face of the members 'com- I prising thespool lOhave lugs 25, and these 1 Fixed by means 12 on the upper edge of the clamp 6 there is a flat arched spring 13. The outer curved end of this spring rests directly on the periphery of the inner member of the spool 10. The tension of the spring 13 is adjusted through the medium of a headed screw member 13" that passes through an. opening in the spring 13 and is received in a threaded opening in the clamp member 6. By this arrangement it will be seen that the spool 10 Will be held from free turning.

Pivotally supported by an adjustable and removable element 14: on one side of the clamp 6 there is a curved arm 15 which is directed toward the front of the head 2. Passing through a suitable opening in the outer end of the arm 15 there is a headed screw 16 which is engaged by a mill nut 17. The screwpasses through an elongated slot in a plate 18 and is,

of course, adjustable on the arm 15.

Also passing through the slot in the plate 18 there is a second headed screw 19 which is engaged by a. mill nut 20. The screw passes through the upper end of a twisted plate 21, the lower end of the said plate being formed with or having secured thereon a guide eye 22 for the tape 23 that is fed from the spool 10. It is to be noted that the arm 15 is swingably attached to the clamp 6; that the plate 18 is both vertically adjustably and swingably attached to the arm 15, and that the eye carrying plate 21 is both vertically and swingably attached to the plate 18, and that by virtue of such arrangement the eye 22 may be properly positioned with respect to the edges of the fabric 2 1 on which the tape is to be stitched, and likewise that the eye can be thus properly positioned upon varying types of sewing machines.

The tape 23 may be centrally folded before passing through the guide eye 22 and by properly adjusting the eye with respect to its support or with respect to the operator of the machine the said tape can be arranged on the edges of the fabric, regardless of irregularities in such edges and easily and effectively as well as properly stitched on such edges in a manner most convenient to the operator. Of

course different sp'ools containing different lengths of tape may be arranged on the stub shaft 8, and spools containing two windings of binding tape may be also employed] As previously stated only one satisfactory embodiment of the improvement is herein set forth and therefore it is to be understood that I hold myself entitled to make such changes and modifications therefrom as fall within the scope of what I claim, providing,'of course that such changes or modifications do not exceed the scope of the claims or depart from the spirit or sacrifice any of the advantages of the invention.

Havlng described the invention I claim:

A sewing machine'attachment for facilitating feeding of binding tape to the machine, comprising a bracket adapted to be mounted upon the head of a sewing machine, means on the bracket for supporting a spool carrying binding material, an arm mounted upon and depending from said bracket, a longitudinally slotted link disposed against the lower end of said arm, a clamping screw provided with a nut carried by said arm and passing through the upper end of the slotted link, a vertically arranged tape guide, a twisted link carrying the binding tape guide, and a second clamping screwprovided with a nut passing through said twisted link and through the lower end of the slotted link.

2. In a sewing machine attachment for facilitating feeding of binding tape to the sewing machine, a bracket adapted to be'mounted upon the head of the sewing machine,

means on the bracket for supporting a spool carrying binding material'; an arm mounted on said bracket, a link pivotally and longitudinally adjustably connected with the lower end of said arm and swingable vertically in a direction at right angles to the plane of the swinging movement of said arm, a second link pivotally and adjustably mounted upon said first named link and swingable in the same plane therewith, said second named link having its lower end twisted at right angl'es, and a guide carried by the lower end of thesecond named link for guiding the binding tape.

In testimony whereof I affix my signature.
