Girl War

On this day in 1830 the so-called ‘Girls‘ War’ was fought between northern and southern Ngāpuhi hapū at Kororāreka (Russell).

Up to 100 people were killed or wounded in the fighting, after which the northern alliance took control of the important settlement.

The conflict had its roots in inter-hapū rivalry and competition for European trade. It was sparked by a fight among some young high-born women, including wives of a European whaler, W.D. Brind. A minor incident led to an exchange of threats between hapū. Events took a violent turn when a woman was accidentally shot.

Brake Air

In this day in 1872, George Westinghouse patents the air brake.

In the air brake’s simplest form, referred to as a straight air system, compressed air is directed to a brake cylinder, causing its piston to apply force to mechanical linkage, which linkage is conventionally referred to as the brake rigging. The brake rigging, in turn, is connected to brake shoes that are pressed against the car’s wheel treads (some types of passenger cars instead use disc brakes). The resulting friction slows the car by dissipating its kinetic energy as heat.
The brake rigging is often quite elaborate, as it is designed to evenly distribute the brake cylinder’s force to multiple wheels.
