Application filed December 27, 1923. Serial No. 682,895.

This invention relates to an attachment for sewing machines intended for usev in sewing hook and eye holding tapes upon brassieres and other garments of wearing I apparel, the present invention being a further development of one disclosed in Letters Patent of the United States No. 1,524,013, dated January 27, 1925. V

In the said Letters Patenta'sewingmation is to provide a novel construction of means whereby the two presser feet and the two needles of the machines which are adapted for simultaneously stitching the 5 opposite-edges of hook and eye tape may be adjusted to adapt them for use in connection with the said attachment in the sewing of hookand eye tape of different widths.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the Fig. is a face View of the needle holder. 1 Fig. '6 is a transverse sectional view taken on the line 6-6 of Fig. 5. V

Fig. 9 is -a sectional plan view taken in the plane of lines 99 in Figs. 11 and 12 of a hook and eye tape ."supporting and guiding chine attachment is shown comprising means The general object of the present inven-- various novel features are more particularly device adapted to be attached to a sewing machine.

Fig. 10 is a similar view taken in the plane of'lines 1010 of Figs. 1.1 and 12. Fig. 11 is a longitudinal central sectional view taken on the line 11'11 of Fig. 9.

Fig. 12 is a, transverse sectional view' taken, on the line 12-12 of Fig. 10.

Fig. 13 is a transverse sectional view taken on the line 13 1s'or Fig. 10.

In Figs. 1, and 9 to 13, inclusive, of the drawing I have shown the hook and eye tape supporting and, guiding attachment by means of which the said tape is supported and guided through the machine in operative relation to the work feeding and sewing mechanism which is illustrated in Figs. 1 to 8 inclusive. The hook and eye tape supporting and guiding attachment comprises a base or bottom portion 10 and atop plate 10 The bottom plate 10 comprises a main or body portion, as clearly indicated in Figs. 1, 9and 10,which is of substantially rectangular shape, and from the forward edge of which projects a tongue-like portion 10 from the opposite edges of the forward end portion of which projections 10 extend. Bars 11 and 12 arranged in pairs as shown in the bottom plate 10. The outer bars 12 are held in adjusted position by means of screws 12*, the bottom end portions of which may be adjusted back and forth in slots 12. The

inner bars 11 are held in adjusted positions by means of screws 12, which may be ad justed back and forth in the slot 12 Mounted uponthe top sidesof the opposite edge portions of the rectangular shaped portion of the base member 1.0 are bars 12 which. are of rectangular shape in cross section; These bars are held in place by the screws 12 Tape guiding plates 12 are mounted above the bars 12 and underneath the opposite'edge portions of the top plate 10 of the attachment. The inner edges of the plate 12 are spaced from each other as clearly shown in Fig. 12 and are adjustable toward and from each other. plates, 12 are held in adjusted, clamped The said position between the top plate 10 and the bars 12 by. means of screws 12 which extend through elongated transversely extending slots. .12 .in the said plates 12 The inner drawing are adjustably mounted upon the edge portions of the plates 12 extend part way over the tops of the bars 11 and 12, previously referred to. As will be apparent upon reference to Fig. 12 of the drawings the opposite edges of the tape 12 are guided bythe inner opposing edges of the guide plates 12 In the employment of the attachment not only may the guide plates 12 be adjusted to accommodate hook and eye tape of different widths, but the bars 11 and 12 may be adjusted. These adjustments will correspond to the adjustments of the presser feet, and needles, as will be described hereinafter and are necessary in order that the said attachment may cooperate in an efficient and satisfactory manner with the sewing mechanism. I

Referring now to the presser foot construction, it will be noted that the presser foot bracket or holder comprises front and rear plates 15 and 16 which are suitably spaced by the'bosses 17'and secured together by screws such as 18. Between these two plates the angular bars 20 and are located. These bars are guided in their adjustments by the bosses 17, The presser feet .22 are hinged to said bars at 23. These bars 20 and 21 are provided with threaded holes 25 which are engaged by headed screws 26 which pass through horizontal slots 27 in the rear plate 16, the heads of the screws overlapping the slot. walls. As will be apparent, by loosening the screws, the bars 20, 21 can be adjustedto move the respective presser feet toward and away from one another. The rear plate 16. is provided with a rearward and laterally extending projection 30 which is provided with an opening 31 whereby it may be attached to the presser bar. The presser feet 22, as will be understood, are positioned above the openings 13 and the feed dogs operating therein. For the purpose of engaging the tape midway between the presser feet 22 and the said openings 13 I have provided a presserfoot element 32 which depends from the front plate 15, with which, in the construction here shown, it is integral. 7 v

The needle holder comprises the rod 35 which is provided with a crossbar 36 on its lower end. Upon this bar 36. is slidably positioned a pair of brackets 37 which are grooved on their rear faces to receive. said bar as shownmost clearly in Fig. 6. These brackets are provided in their lower portions with upwardly extending sockets to receive the upper end of the needles 38, whiehare fastened'in placeby set screws 39.

The brackets 37 are formed with longitudinal slots 10 of T-1form in cross section through: which pass headed 41 which are threaded into. suitable. tapped holesv ad- :j aeent the opposite ends of the bar By e s nin ese sets u flii issls d e b adjusted inwardly orioutwardly with the at the two needles at equal distance from the J median plane of the device. As here shown the bar 36 is formed with a longitudinal slot 45 in which it positioned a gage block 46 which is stepped evenly from the center to the ends along one edge as at 47. Passing 3 freely through the bottom wall of the slot and threaded into a suitable socket in the block 46 is a screw 18 which is held against axial displacement by a member d9 engaging the head thereof. By rotating 2 this screw the block 46 can be projected varying distances from the bottom of the slot 45. The shoulders formed by the steps 1? operate as stops to limit the inward adjustments of the needle holding parts 37. .1

The positionsof thefshoulders depend upon the position of the block 416 with respect to the slot 45.

Having thus described my invention what I claim as new and desire to protect by 1 Letters Patent of the United States is as follows.
