Reference excerpt

The Singer Featherweight is a model series of lockstitch domestic sewing machines produced by the Singer Manufacturing Company from 1933 to 1968, significant among sewing machines for their continuing popularity, active use by quilters and high collector's value.

Design

A typical early 20th century sewing machine, like the Singer 27, was designed to be mounted in a treadle or table, and though reduced-size models with hand cranks and wooden cases were introduced, their weight strains the meaning of the word 'portable.' The first sewing machine designed for portability, with a completely enclosed movement, was invented in 1928 by Raymond Plumley and Richard Hohmann, engineers for the Frederick Osann Company, who took advantage of then-recent advances in alloy technology to create a machine housed in a lightweight cast aluminum body. Osann subcontracted manufacture and assembly to the Standard Sewing Machine Company of Cleveland, Ohio, which marketed the machine under a number of brands, including Osann, Standard, and General Electric. Both companies encountered financial difficulties as the Great Depression worsened; Osann was acquired by Standard, which was in turn acquired by the Singer Manufacturing Company. Singer continued production of the Sewhandy under the Standard brand through the early 30s while working on an improved design, which would be introduced as the Model 221 during the 1934 World's Fair. Like the Sewhandy, the 221 featured aluminum construction and small size, weighing only 11 pounds (5.0 kg), as well as an improved self-fastening bobbin case which simplified the design of the machine's bobbin driver.

Production It is estimated that Singer produced and sold some 3.0–3.5 million Featherweight machines during the model's lifetime. Production of the original Featherweight ended in 1961, but continued at Singer factories in Quebec and Scotland until 1969. Later British versions have numerous cost-saving components including a belt drive and a simpler front thread guide. An especially sought-after free arm version, Model 222K, was produced in Scotland from c.1953 to c.1961 exclusively for the non-US market.

Attachments

A number of attachments are available for the Featherweight, including the following feet:

Foot hemmer – used for hemming, making hemmed and felled seams, and for sewing on lace while hemming Adjustable hemmer – to make hems from 3/16" to 15/16" wide Multi-slotted binder – to apply unfolded bias binding 15/16" in width and folded bias bindings in sizes 1–5 (1/4" – 1/2"), or to add piping Edge-stitcher – replaces the presser foot, used to accurately stitch at the very edge of the fabric Gatherer – used to slightly gather material Ruffler – to make and apply ruffles in one step, to pipe ruffles, or to pleat material

Worked examples

Example 1 — a first encounter with Singer Featherweight

Start with the simplest possible case. Write down what Singer Featherweight claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Singer Featherweight before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Singer Featherweight ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Singer Featherweight

In research: Singer Featherweight appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Singer Featherweight in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Singer Featherweight is common in secondary-school and first-year university syllabi. It links to neighbouring topics Sewing machines, so understanding it makes those chapters shorter.
In everyday life: Look for Singer Featherweight outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
