Lost a button, snapped a strap; need something to hold it, or fix it? It’s the thing to reach for in an emergency. From the diaper to the toddler’s hanky, the sari pallu to the Scottish kilt, from the school badge to the split seam, this is what holds it together. It is the simple but multipurpose safety pin! Of all the many inventions that have made our day-to-day life simpler, it is these small but unsung ones that hardly ever make it to the headlines, but without which we would be quite lost.
The story of the safety pin is one of those. Its inventor Walter Hunt came from humble beginnings. He was born on a small farm in Lewis County, New York in 1796, the eldest of 13 children. He started his education in a one-room school, and dropped out of formal education in his early teens to take to farming. While Hunt was not keen on the 3Rs, his mind was sharp and curious, and he was fascinated with mechanical objects. This led him to help out at a nearby textile mill where several of his family members worked. With his love for tinkering, he worked out some improvements to the flax spinning machine used there. The owner took out a patent on this, but Hunt was not included in that. Hunt however went on to develop an even better flax spinning machine which he patented. But he could not find any investors who would support the production of these machines. Eventually, in frustration, he sold the patent, just to support his family, and relocated to New York.
This was in the days before the motor car. One day he saw a little girl being knocked down by a horse carriage which was the mode of transport. These carriages had air horns to warn the pedestrians who shared the roads, but the driver could not use the horn as he had to hold the reins with both hands. Hunt observed this issue, and developed a foot-operated metal gong to sound the horn. In 1827, he filed a patent for this device. Once again, he could not find an investor to manufacture this device, and so once again he sold the patent. And never made any money from the profits from the sales of his invention.
This was to be the pattern of Hunt’s life. He was always in the need for quick money to support his family, and so he sold his patents outright rather than holding on to them, or opting for the longer-term profits from royalties. Luckily for him, he could also come up with invention after invention.
It was one of those patents that he sold in 1849 that gave us the nifty device we call the safety pin. Here too was a case of a quick invention for quick money. In this instance, he was being pressured to settle a 15-dollar debt, which had to be repaid the following day. As was his default setting, he sat at night tinkering with a piece of wire, while wondering what new product he could invent and sell the next day. The wire reminded him of a pin, which in those days was straight length of metal with a sharp edge. Hunt wondered how he could make the pin less prone to poke the user, and thereby more safe. In 3 hours, he worked out a sketch, and made a tiny model of a new type of pin. He used a brass wire, coiled it at the centre which provided a springing mechanism, and formed a clasp or catch on one end which shielded the wearer from being the sharp point when worn. He called this a ‘dress pin’.
As he described in his patent application: “The distinguishing features of this invention consist in the construction of a pin made of one piece of wire or metal combining a spring, and clasp or catch, in which the point of said pin is forced, and by its own spring securely retained.”
He then sold the patent outright for $400, and never got a single penny more for a product that has sold in trillions across the world, over more than a hundred and seventy five years.
The dress pin was only one of Hunt’s many inventions. Earlier, in 1834, he had designed one of the world’s first eye-pointed-needle sewing machines. But his daughter talked him out of commercializing the device by warning him that it would lead to massive unemployment among seamstresses. He created a prototype in wood of the sewing machine, and sold the idea to a company that made it in metal. And in history, the credit for the invention went to Isaac Singer, and the Singer sewing machines became a household name.
Hunt continued his prolific spree of improving upon, inventing, and patenting numerous other daily-use objects. These included for a saw for easily cutting down trees, a flexible spring attachment for belts and suspenders, and an attachment for boats to cut through ice. He developed a machine for making nails, hob nails for boots and shoes, a knife sharpener, an inkstand, a fountain pen, bottle stoppers, paper shirt collars, and a non-explosive lamp. He developed a repeating gun and cartridge that was eventually adapted by Smith and Wesson. He even invented an suction apparatus that could be attached to shoes so a person could walk upside down on a ceiling. The contraption was used by circus performers as late as 1937.
Walter Hunt died on June 8, 1859 at the age of 62, with perhaps as many inventions under his hat as his years on earth. All his life he continued to outright sell his patents, and did not reap a single penny in royalties. His only claim to fame, if not fortune, is that 10 April has been designated as International Safety Pin Day, to mark the day on which he received his patent for the safety pin!
