Gilson Brothers Co.

Gilson Brothers Co. 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 Gilson Brothers Co. rather than just read about it. In short: Gilson Brothers Co. was a Wisconsin-based manufacturer of outdoor power equipment and recreational equipment. It operated independently between its inception in 1911 until acquisition by Lawn-Boy in 1988.

Key takeaways

Gilson Brothers Co. belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Gilson Brothers Co. to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Gilson Brothers Co. was a Wisconsin-based manufacturer of outdoor power equipment and recreational equipment. It operated independently between its inception in 1911 until acquisition by Lawn-Boy in 1988. The company was probably most well known for its garden tillers, snowblowers and garden tractors produced from the 1960s through the 1980s.

History John P. Gilson and his brother Michael Gilson were descendants of Theodore Gilson, who had emigrated to the United States from Colmar-Berg, Luxembourg and, in 1850, started what eventually became the Gilson Manufacturing Company. Brothers John and Michael, having both worked for that company, started the Gilson Brothers Company in 1911. At that time, the Gilson Brothers' main products were limestone grinders, feed cutters, and concrete mixers. In 1988, Gilson Brothers Co. was acquired by Lawn-Boy, which was itself acquired by the Toro company in the following year. It was at this point that production of Gilson-branded lawn and snow equipment ceased. The Gilson line of concrete mixers was sold to the Cleform company of Missouri, which was acquired in 2010 by the Marshalltown Company of Marshalltown, Iowa. As of January 2011, that company still sells concrete mixers under the Gilson name.

Products

Gilson Brothers Co. has produced a wide range of products, including:

Crushers Rotary tillers Feed cutters Concrete mixers Minibikes Snowmobiles Barbecue grills Snowblowers and snowthrowers Lawn and garden tractors Tillers Those Gilson Brothers products that were sold under the Gilson brand were typically painted with the company's signature beige-and-crimson color scheme, starting in 1977 they used crimson-and-black. Gilson Brothers products were also re-branded and sold under the names Montgomery Ward, Lawn-Boy, Ford, Snow Charger, Wizard, Plymouth, Marshall Wells, and others. Most Gilson snowblowers were powered by Briggs & Stratton engines.

UniTrol

UniTrol (or Uni-Trol) was a patented Gilson Brothers innovation in snowblower drive linkage that allows operation of the clutch and gearchange with a single lever. It was introduced in 1969 and was available on Gilson snowblowers until 1979. When a UniTrol snowblower is running, the engine is always turning a drive platter. The act of engaging a gear presses a rubber-edged wheel against the flat steel surface of the spinning platter, which transfers power through 90 degrees to the drive axle and at a ratio inversely proportional to the distance from the center of the platter at which the wheel is engaged. A neutral "gear" is available by simply lifting the wheel from the surface of the platter, and a reverse gear is available by engaging the wheel at a symmetric point across the center of the platter. The style of baffle used in the single-speed UniTrol snowblowers was also patented for its unique design.

Snow Cannon The "Snow Cannon" was the Gilson line of compact snow throwers, for which a patent was granted in 1980. These machines were powered by two-stroke engines (manufactured either by Briggs & Stratton, Tecumseh or OMC (Outboard Marine Corp). The throwing mechanism on the Snow Cannon machines was advertised with the marketing term "TURBO-THRUST".

Worked examples

Example 1 — a first encounter with Gilson Brothers Co.

Start with the simplest possible case. Write down what Gilson Brothers Co. 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 Gilson Brothers Co. 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 Gilson Brothers Co. 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 Gilson Brothers Co.

In research: Gilson Brothers Co. 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 Gilson Brothers Co. 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: Gilson Brothers Co. is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1911 establishments in Wisconsin, 1989 disestablishments in Wisconsin, Defunct manufacturing companies based in Wisconsin, so understanding it makes those chapters shorter.
In everyday life: Look for Gilson Brothers Co. 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.
