Absurd patent of the month: N°US556248
Publié le 28 October 2024

Today we present a saluting device dedicated to hats!

Filed by Mr. James C. Boyle in the United States in 1896, this patent application (No. US556,248) describes a small device designed to be hidden within a hat, which is used to greet our interlocutors.

 

Brevet insolite dispositif de salutation

As you probably know, at the time, it was customary for a gentleman to greet acquaintances by raising his hat with a hand and slightly tilt the head.

This invention saves energy by avoiding having to lift the hat 50 times a day, as the device handles it for you. The removable apparatus, hidden inside the hat, allows for the hat’s elevation and rotation, then correctly repositions it on the head. Held on the head by curved rods that shape the user’s skull, it activates as soon as the wearer bows his head and then returns to an upright posture.

Obviously, this was not designed for ladies since at the time only men were expected to uncover their heads. The level of sensitivity needs to be carefully adjusted: the hat shouldn’t lift every time one bows their head. Nowadays, with smartphones, that would be impossible… and quite amusing. And, a subsidiary question: does it work for bald people too?

 

P.S. The inventor also indicated that his device could be used as an advertising medium… If this gives you fresh ideas to develop a modern, app-connected version of this invention, feel free to share with us!
