A wheelock refers to a type of firearm mechanism commonly known as a matchlock. The term originated from the combination of two words: "wheel" which signifies the element responsible for igniting the gunpowder, and "lock" which refers to the mechanical component that holds, releases, and ignites the gun's firing mechanism.
The wheelock was widely used during the 16th and 17th centuries before being replaced by more advanced systems such as the flintlock. It consisted of a circular metal wheel that had a serrated edge. A spanner, a lever or key-like device, was used to wind a spring that provided the necessary tension to rotate the wheel. The wheel was made to spin by the action of a trigger. A piece of iron pyrite, also known as a tinder, was clamped on a movable arm adjacent to the wheel that created sparks upon hitting it. These sparks were then directed into a small pan containing gunpowder, located beside the barrel, which ignited and propelled the shot.
Wheelocks were renowned for their reliability and accuracy compared to their predecessors. However, they were also quite cumbersome to use due to the need for separate ignition tools, such as the spanner and tinder, which increased the complexity and time required to fire the weapon. Despite its eventual obsolescence, the wheelock holds a significant place in the history of firearms as a transitional step between matchlocks and more modern ignition systems.
