wheel lock

Thân thiện

A soldier loads his musket, carefully checking the wheel lock mechanism.

Definition

Noun: 1. An obsolete type of firearm ignition mechanism: A "wheel lock" is a historical firing mechanism for guns, preceding the flintlock. It operated by using a spring-driven, serrated steel wheel that spun against a piece of pyrite or iron pyrite to generate sparks, which ignited the gunpowder in the priming pan.

Usage

The term "wheel lock" is used specifically to refer to this antiquated technology, primarily in historical, military, or collecting contexts. * It functions as a compound noun, where "wheel" describes the key rotating component of the "lock" (the firing mechanism). * It is typically used attributively to describe the guns that employed this mechanism (e.g., a wheel-lock pistol).

Examples

• Noun:
  • The museum's collection includes a rare 16th-century wheel lock.
  • The invention of the wheel lock allowed for more reliable firearms that could be carried ready to fire.
  • He is an expert in restoring antique wheel-lock mechanisms.

Advanced Usage

• The term is often hyphenated when used as an adjective preceding a noun (wheel-lock pistol, wheel-lock rifle).
• It can be used metonymically to refer to the firearm itself, though it is more precise to say "wheel-lock gun" or "wheel-lock firearm."

Variants and Related Words

• Lock: In this context, the general term for a gun's firing mechanism.
• Flintlock: The successor ignition system that replaced the wheel lock.
• Matchlock: The simpler, preceding ignition system that used a slow-burning matchcord.

Synonyms

• Arquebus lock (historical, though an arquebus could use a matchlock or wheel lock).

Related Phrases and Idioms
