A throat plate of a sewing machine with a feed plate is provided with disc type bearings retained in fixed position adjacent to the needle hole of the throat plate to support and provide low friction surfaces in contact with the feed plate.

Anti-friction apparatus for cloth feedplate

In a twin needle tacker in which one needle/bobbin assembly is movable relative to the other to change the space between the tacks, a feed plate assembly and a throat plate assembly each having one plate movable relative to the other for realigning the slots of the feed plate assembly and the needle holes of the throat plate assembly with the needles; and a twin knife mechanism operatively interconnected having a first cutting means mounted on the bottom of one throat plate and the other cutting means mounted on the bottom of the other throat plate.

Twin needle with adjustable throat plate and feed plate

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

Pocket positioning apparatus

Apparatus for simultaneously cutting both needle threads and both bobbin threads for a twin needle tacker or the like; the apparatus being mounted to the bottom of the throat plate and being removable with the throat plate as a single unit.

Knife mechanism for twin needle sewing apparatus

A sewing head employing twin needles for use with a material feed assembly at a sewing station, employing a linkage drive configuration enabling original rotary motion to be converted into linear rather than arcuate during formation of tacks. The same drive source is employed for both longitudinal and lateral motion, with a movable link added into the main feed link assembly. By means of a guide member, one portion of the main drive is confined to longitudinal motion only, while the other portion is free to go through the lateral motion separately. By employing an additional movable link and designing the main feed link as a two part link, while at the same time employing the same drive source for longitudinal and lateral motion, it is possible to achieve the necessary linear parallel motion. By the aforementioned arrangement, the drive link achieves linear motion and provides for a uniform tacking pattern for both needles. Spacing between tacks can be varied by horizontal adjustment of the needle-bobbin assemblies.
