In­ven­tion: Re­tractable dog lead Year: 1908

In­ven­tor: Mary A De­laney

This sim­ple but clever in­ven­tion has al­lowed dogs to have more free­dom dur­ing their daily walks, while still al­low­ing their own­ers to have con­trol over them and shorten the lead if they need to – thanks to a long lead coiled around a drum, and a spring mech­a­nism.

In­ter­est­ingly, al­though we talk about tak­ing our dogs for a walk, De­laney said the lead was for when dogs “are taken out to ac­com­pany a per­son in his or her walks”!
