## Abstract

Apparatus in conjunction with a twin needle tacker to facilitate loading and simultaneously tacking both ends of a rear or hip pocket opening.

## Claims

### Claim 1

A method of simultaneously tacking both ends of a pocket opening with a twin needle tacker type sewing machine providing a sewing station, comprising the steps of
providing guide means at the sewing station;
fitting a pocket on said guide means thereby positioning the ends of the pocket opening relative to the needles;
clamping the ends of the pocket openings in position and removing the guide means from the sewing station; and
moving the clamping means and the pocket opening along longitudinal and lateral axes while simultaneously tacking both ends of the pocket opening.

### Claim 2 (depends on 1)

The method in accordance with claim 1, further comprising the steps of
releasing the pocket by said clamping means; and
returning said guide means to said sewing station.

### Claim 3 (depends on 2)

The method in accordance with claim 2, and
providing a feed plate at the sewing station;
moving the pocket by said guide means on to the feed plate; and
thereafter clamping the ends of the pocket opening against the feed plate.

### Claim 4

In combination with a twin needle tacker type sewing machine providing a sewing station, apparatus for simultaneously tacking both ends of a pocket opening, comprising
guide means disposed at the sewing station for receiving a pocket of a garment and positioning the ends of the pocket openings relative to the needles;
a feed plate disposed at the sewing station below said guide means;
means for moving said guide means to position the pocket on said feed plate;
means for clamping the ends of the pocket opening against the feed plate;
means for withdrawing said guide means from the pocket and away from the sewing station after the ends of the pocket opening are clamped; and
means for moving said feed plate and clamping means with the pocket opening therebetween in unison along longitudinal and lateral axes while simultaneously tacking both ends of the pocket opening.

### Claim 5 (depends on 4)

The apparatus in accordance with claim 4, and said guide means comprising
a pair of laterally spaced fingers substantially parallel to each other extending forwardly above the feed plate for receiving a pocket;
said fingers being spaced to engage the ends of the pocket opening for lateral positioning relative to the needles;
said fingers each having a stop extending upwardly therefrom engaging the edge of the pocket thereby longitudinally positioning the ends of the pocket opening relative to said needles.

### Claim 6 (depends on 5)

The apparatus in accordance with claim 5, and
one of said fingers being pivotally mounted and spring biased to pivot away from the other of said fingers; and
the other of said fingers being adjustably mounted to vary the lateral spacing between said fingers.

### Claim 7 (depends on 6)

The apparatus in accordance with claim 6, and said guide means further comprising
a mounting bracket releasably connected to said sewing machine; and
means to laterally vary the position of said bracket relative to said sewing machine for laterally positioning said pair of fingers relative to said twin needles.

### Claim 8 (depends on 7)

The apparatus in accordance with claim 7, and said guide means further comprising
a bracket member connected to move relative to said mounting bracket;
a carrier connected to move relative to said bracket member;
said laterally spaced fingers being connected to said carrier;
first motor means for moving said bracket member vertically thereby moving said pair of fingers toward and away from said feed plate;
said motor means for moving said carrier longitudinally thereby moving said pair of fingers toward and away from said sewing station; and
an adjustable stop to limit the downward movement of said bracket member and prevent said pair of fingers from clamping a pocket against said feed plate.
