Protector Palm Pistol

Protector Palm Pistol 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 Protector Palm Pistol rather than just read about it. In short: The Protector Palm Pistol is a small revolver designed to be concealed in the palm of the hand. It was unique in that the revolver was clasped in a fist with the barrel protruding between two fingers and the entire handgun was squeezed in order to fire a round.

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

Reference excerpt

The Protector Palm Pistol is a small revolver designed to be concealed in the palm of the hand. It was unique in that the revolver was clasped in a fist with the barrel protruding between two fingers and the entire handgun was squeezed in order to fire a round. The design was meant to resemble a pocket watch to the extent of being carried on a chain.

History The Protector Palm Pistol was first patented and built in France in 1882 by Jacques Turbiaux and sold as the "Turbiaux Le Protector" or the "Turbiaux Disc Pistol". Later in 1883 it was built in the USA as The Protector by Minneapolis Firearms Co. Peter H. Finnegan of Austin, Illinois bought the patent in 1892 and founded the Chicago Fire Arms Co. to make and market the pistols. In anticipation of the World's Columbian Exposition in 1893, he contracted the Ames Sword Company of Chicopee, Massachusetts to manufacture 15,000 pistols. Ames made 1,500 of the pistols by the deadline of the exhibition. Finnegan sued for damages and engaged in a lawsuit with Ames. The company countersued and settled with Finnegan, but, through the years, had amassed a large production run of 12,800 pistols. The company sold the inventory and abandoned the design by 1910. Remington manufactured the rimfire ammunition for this pistol, 32 Extra Short and alternatively 32 Protector, until 1920. Most Protectors were nickel-plated to prevent corrosion from being carried in close contact with the owner. These guns were shipped with hard rubber inserts for additional protection. Some varieties came with pearl inlays and a small percentage were blued.

Operation

The design of these pistols was based on that patented by Jacques E. Turbiaux of Paris. Turbiaux described his pistol as "a revolver which may be held in the hand with no part exposed except the barrel". The protector was designed to be the size of a pocketwatch and is a unique pistol in that it is not fired using a conventional trigger, but by the operator squeezing their fist when the pistol is in the hand. The guns were made in a few different calibres. Surviving examples have been noted in 6 mm, 8 mm, and .32 caliber. 6 mm is marked on some surviving boxes of the French version, and .32 caliber is noted on the boxes of the Chicago Fire Arms Co. pistols. The European and American versions used different designs of safety catches with the European pistols having two different versions of their sliding bar safety.

Worked examples

Example 1 — a first encounter with Protector Palm Pistol

Start with the simplest possible case. Write down what Protector Palm Pistol 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 Protector Palm Pistol 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 Protector Palm Pistol 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 Protector Palm Pistol

In research: Protector Palm Pistol 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 Protector Palm Pistol 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: Protector Palm Pistol is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ames Manufacturing Company, Concealable firearms, French inventions, so understanding it makes those chapters shorter.
In everyday life: Look for Protector Palm Pistol 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.
