Van Ness Ave., Inglewood, Calif. 90303 Filed May 16, 1968, Ser. No. 729,646 Int. Cl. Db 3/16 US. Cl. 112-114 3 Claims ABSTRACT OF THE DISCLOSURE An accessory for industrial sewing machines to facilitate sewing shank buttons to garments that are in production, said accessory comprising: a bracket (12) to be mounted on the attachment arm (11) of an industrial sewing machine, said bracket carrying opposed fingers (14 and 15) for guiding each contacting shank button (19) toward a position in which the eyelet (23) in its shank portion will receive the sewing machine needle on its next downward stroke, there being a spring-loaded pressure foot (21) for urging the button toward said fingers, and means for varying the tension applied by said pressure foot.

Summary An accessory to be mounted on the attachment arm of an industrial sewing machine for guiding each shank button individually toward a position in which the eyelet 23 in its shank will receive the sewing machine needle in its next downward stroke, said accessory comprising spring-loaded means for urging said buttons toward said position.

In the drawings:

FIGURE 1 is an isometric view of the attachment arm of an industrial sewing machine with the shank button tacker attachment connected thereto;

FIG. 2 is a side elevation of the shank button tacker attachment showing the left end of the attachment arm of the sewing machine in phantom and broken away;

FIG. 3 is a view taken on line 33 of FIG. 2;

FIG. 4 is a view taken on line 44 of FIG. 2; and

FIG. 5 is a view taken on line S5 of FIG. 4.

In the presently preferred embodiment of the invention, as illustrated in the drawings, the shank button tacker attachment is connected to the left end of the sewing machine attachment arm 11 by means of two hexagonalheaded screws 18a and 18b that extend through the

mounting holes

35 and 36 in bracket 12 and are threaded into the arm 11. The left end of bracket 12 is channelshaped and comprises a pair of spaced legs 33 FIG. 2 and 34 FIG. 2 that depend at right angles from the flat top portion of the bracket whose right end overlaps the left end of the attachment mounting arm 11 of the sewing machine.

The right leg 34 of bracket 12 carries two opposed fingers 14 and 15 (FIGS. 2 and 4) that are so spaced that the eyeletted end 20' of the button shank of a button 19 having an eyelet 23 will not fit between them unless the shank is positioned horizontally as shown in FIG. 4 so that the axis of the eyelet will be disposed vertically to permit the sewing machine needle to pass thcrethrough. Numeral 27 indicates slots through which socket screws 30 mount finger 14.

Numerals

28, 29 indicate socket screws for mounting finger 15. The left leg 33 supports the leaf spring 22.

The button tacker is provided with an adjustable shank stop 13 which is secured to the top surface of the mount- 3,469,546 Patented Sept. 30, 1969 "ice ing bracket 12 by means of two socket screws 17 that pass through the longitudinally extending slot 16 and thence into threaded holes in the bracket 12. The slot 16 is sufliciently long to permit the adjustable shank stop 13 to move longitudinally as far as any adjustment would require.

The shank stop has an arm 31 that slopes downward to its lower end 32, which lies in a plane that is perpendicular to the top slotted plate of the adjustable shank stop. This lower end 32 is the portion of member 13 that limits the movement of the eyeletted shank of the button in the direction of the attachment mounting arm 11, as clearly shown in FIG. 1 where the end of the eyeletted shank may be seen in engagement with the back stop 32.

The pressure foot 21 is secured to the lower end of the pressure adjusting screw 26, as shown in FIGS. 1 and 2. This screw is threaded through an internally threaded boss 25 that is integrally secured to the leg 24, which is riveted or otherwise securely fastened to the leaf spring 22.

Various modifications may of course be made from the illustrative embodiment hereinbefore described, and numerous substitutions, reversals, transpositions and additions may be made without departing from the broad spirit of the invention.

The inventor claims:

1. An accessory for industrial sewing machines to facilitate the tacking of eyeletted shank buttons, said accessory comprising: a bracket to be mounted on the attachment mounting arm of an industrial sewing machine, said bracket having a pair of spaced members depending therefrom, one of said members carrying opposed fingers for substantially engaging opposite sides of the eyeletted shank of a shank button when the shank of the button is so oriented that the axis of the eyelet is transverse to the top surface of the bracket; a leaf spring for urging the button towards said fingers, the other of said members serving as a support for one end of said leaf spring; and a pressure foot for urging the button toward said fingers; said pressure foot adjustably mounted on the unsupported end of said leaf spring.

2. The combination set forth in claim 1 in which an internally threaded boss is secured to the free end of said leaf spring, and in which a manually rotatable screw is threaded through said boss for varying the pressure of said pressure foot.

3. The combination set forth in claim 1 with the addition of means for limiting the movement of the eyelet in one direction, said adjustable element comprising a plate having a slot therein that is substantially parallel to said members, there being a pair of clamping shoulder screws passing through said slot, the diameter of said shoulder screws being greater than the width of said slot, said means comprising an arm depending from the main body of said plate to provide an abutment that is engageable by said eyelet.
