Sewing Machine Combination

Sewing Machine Combination is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sewing Machine Combination rather than just read about it. In short: The Sewing Machine Combination or the Sewing Machine Trust was the first patent pool in US history. It was formed by the "Albany Agreement" of 24 October 1856 and lasted until its last patent expired in 1877.

Key takeaways

  • Sewing Machine Combination belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Sewing Machine Combination to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Sewing Machine Combination from memory before moving on to harder problems.

Reference excerpt

The Sewing Machine Combination or the Sewing Machine Trust was the first patent pool in US history. It was formed by the "Albany Agreement" of 24 October 1856 and lasted until its last patent expired in 1877. It existed for the purpose of reducing the licensing and litigation overhead being imposed by the patent thicket known as the Sewing Machine War. Prior to the Sewing Machine Combination, companies could purchase rights from Elias Howe for a royalty fee of $25 for every machine sold. In 1856, president of the Grover & Baker company, Orlando B. Potter, worked with Howe, Wheeler & Wilson, and Isaac Singer's I. M. Singer and Company to pool their patents and agree to terms of use. The requirements were: at least 24 manufacturers were to be licensed; the founding companies would equally share the profits; and Howe would receive a $5 royalty for each machine sold in the U.S. and $1 for exported machines. Interests only were pooled, prices were not set, and the market was open to fair competition, which allowed companies to concentrate on manufacturing and marketing the machines, rather than litigation. Of the nine patents pooled, three were particularly crucial: the lockstitch, the four-motion feed, and the combination of a vertical needle with horizontal sewing surface. In addition to its four member companies, dozens of other companies licensed its patents, for which they paid royalties and submitted annual production reports. Twenty years after the Combination expired, only two of the companies remained in business.

Worked examples

Example 1 — a first encounter with Sewing Machine Combination

Start with the simplest possible case. Write down what Sewing Machine Combination 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 Sewing Machine Combination 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 Sewing Machine Combination 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 Sewing Machine Combination

In research
Sewing Machine Combination 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 Sewing Machine Combination 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
Sewing Machine Combination is common in secondary-school and first-year university syllabi. It links to neighbouring topics Patent pools, Sewing machines, so understanding it makes those chapters shorter.
In everyday life
Look for Sewing Machine Combination 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.
