Class 15 Survey Results


There are 6 machines in the survey ranging from 1904 - 1952, 2 treadles (1904, 1923), 2 electric knee lever (‘33,’49), and 2 electric foot pedal (‘49, ‘52).

All had a round side loading bobbin.

Bobbin winding varied: 1 machine had thread go through a cleat on the bottom right side, 4 machines had thread go through tension disks on bottom right side, and 1 machine did not have anything on bottom right side.

Balance wheel: 2 spoked and chrome edged (‘04, ‘23), 1 solid and chrome edge (‘33), and 3 solid black (‘49-’52). All machines had shiny black finishes. 5 machines don’t have flat face plates and 1 survey reported a flat face plate.

The designs on the face plates included 1 with floral, 3 lined, 2 other. The plate on the back, right side, is surveyed as 5 round and 1 upside down pear shaped with the following designs: 1 floral, 3 lined, 1 art deco (1 not described).

I received 6 different Reponses on the stitch length adjuster: 1 unmarked knob (‘04), 1 unmarked knob in short slot (‘23), 1 thumb screw in numbered slot (‘33), 1 flat lever in numbered slot (‘49), 1 other (‘49) and 1 not described (‘52). The early machines had no reverse stitch (‘04,’23), the rest of the machines (4) did have reverse.

None of the machines had zigzag.

The upper thread tension was: 3 unmarked on left side (‘04 - ‘33), 2 numbered on left side(‘49s), 1 numbered in front ? (‘52).

The machines had assorted decals and the large 1 5/8 inch Singer medallion.

The head measures 13.5 inches from face plate to far end of balance wheel. The bed measures 14.5 inches by 7 inches.

It has a straight needle and low shank.

There was no light on the 2 treadles. The later machines have a light mounted in back. There is 1 portable in a bentwood case and 3 electrics in cabinets.
