The phrase "Tilt hammer" refers to a type of industrial hammer used to forge metal. It is spelled "tɪlt ˈhæmər", with the "t" pronounced as a voiceless alveolar stop, the "i" as a short vowel, and the "l" pronounced with the tip of the tongue touching the alveolar ridge. The "h" is pronounced as a voiceless glottal fricative and the "a" as a short vowel. The secondary stress falls on the second syllable, and the "er" is pronounced as a schwa sound.
A tilt hammer is a type of industrial forging hammer that is typically operated by water or steam power. This heavy-duty mechanical device is designed to deliver powerful downward blows to a workpiece, mainly used for shaping metal objects, such as iron or steel.
The tilt hammer derives its name from its characteristic tilting motion, where it pivots on a fulcrum and inclines towards the workpiece before delivering the blow. It is composed of a large hammer head, often made of cast iron, mounted on a massive wooden or metal beam. The beam is attached to a vertical axle and can be raised and lowered by the power source, be it water wheel or steam engine.
As the power is applied, the tilt hammer is raised to its highest position, then released to freefall onto the metal piece below. The weight of the hammer head, combined with the force of gravity and the additional momentum from the power source, delivers a powerful strike, effectively shaping and working the metal. The controlled motion and immense force of the tilt hammer makes it particularly suitable for heavy forging tasks, such as shaping large iron components for machinery or constructing metal tools and armor.
Due to its mechanical nature and requirement for a power source, the tilt hammer played a significant role in the development of industrialization and the rise of modern manufacturing. However, it has largely been replaced by more efficient and versatile forging techniques, such as hydraulic or pneumatic hammers, as technology has advanced.
A large hammer set in motion by machinery, and lifted or tilted by projection of wipers of the axis of a wheel used in the manufacture of iron.

The word "tilt" in "tilt hammer" comes from the Middle English "tilten" which means "to run or rush". It is derived from the Old Norse word "tílask" which means "to leap, jump, or hasten".
The word "hammer" comes from the Old English "hamor", which can be traced back to the Proto-Germanic word "hamaraz", meaning "stone tool" or "hammer". This word is also related to the Old Norse word "hamarr" and the Old High German word "hamar".
In combination, "tilt hammer" refers to a type of large mechanical hammer or power hammer that is used in blacksmithing or other industrial processes. The term likely originated from the motion of the hammer rushing or leaping down onto the workpiece.
