Henry Seely's 1882 Electric Flatiron

An 1882 patent for the first electric flatiron, which used internal heating elements to replace the heavy, fire-heated irons of the Victorian era.

What it covers

The patent describes a device that uses electrical resistance to generate heat within the body of a laundry iron. By passing an electric current through a resistive heating element inside the iron's metal base, the device maintains a consistent temperature for smoothing fabric. This eliminated the need to heat the iron on a stove, which was the standard method for centuries.

What it doesn't cover

• —Does not cover steam-based ironing systems.
• —Does not cover cordless or wireless charging technology for irons.
• —Does not cover modern temperature-controlled thermostats or sensors.
• —Does not cover irons that use external heat sources like gas or coal.

The clever bit

The invention cleverly repurposed the concept of electrical resistance—already known in telegraphy and lighting—to create a controlled, portable heat source for a common household tool.

Why it matters

This invention marked the transition of household chores into the electric age. It is a foundational piece of history for modern domestic appliances, shifting the burden of labor from manual fire-tending to electrical convenience.
