June 22 – Pin-Making Machine Patented

Posted on June 22, 2014

Before this date in 1832, Americans bought pins made by hand in 18 separate steps.

What happened on this date in 1832? An American doctor named John Howe patented a machine that quickly manufactured pins in just one step!

More patents followed – one by Howe improving his pin-making machine, and several by his workers for machines that stacked pins or packaged them.

A straight pin is a piece of iron wire with a larger “head” on one end (to help people use it and to hold it in place) and a sharp point on the other end. Pins are most commonly used to hold pieces of fabric together but are sometimes used to attach papers as well.

The pin itself is ancient. Even prehistoric people made and used pins – although they tended to be made from thorns or bone or ivory. Ancient peoples also crafted pins out of bronze, silver, gold, and brass; these ancient pins often had highly decorative heads.

The modern iron straight pin was used as least as early as the 1400s, in France, and there are mentions of pins or “papers of pins” as part of a tailor's equipment from many areas of Europe at that time.

By the 1700s, pin-making was “industrialized” – which means that the labor of making a pin was divided among many people. Each person could become an expert at one step of the pin-making process, and could handle just one piece of equipment – making the process go faster. Adam Smith even used a pin factory as an example of the efficiency of the division of labor.

With this division of labor, a factory could churn out 5,000 pins a day.

With Howe's machine, a factory could churn out 70,000 pins a day! That's 14 times as many!

But the packaging step was still slow until 1843, when Howe and his workers developed a machine to crimp paper and insert the pins in the paper.

Do some pin art!

July 9, 2012 - Happy Birthday, Elias Howe


This is the guy who is often called “the inventor of the sewing machine.”

But he didn't precisely invent the sewing machine.

Born on this date in 1819, Howe may have seen and used others' sewing machine inventions—one was invented as early as 1790, almost 20 years before Howe was born!—but Howe made a great many improvements to others' designs. In 1846 he was awarded the first United States patent for a sewing machine (others had patented their inventions in other countries, apparently earlier than Howe).

Howe invented three things still used in most modern machines:
  • a needle with the eye at the point
  • a shuttle operating beneath the cloth to form the lock stitch
  • an automatic feed

An inventor named Walter Hunt had apparently invented a sewing machine without all of these advances about a decade before Howe's invention. But he didn't get a patent, and he didn't move to manufacture his machine, because he feared that his invention would cause unemployment for seamstresses.

When Howe patented his own sewing machine and tried to manufacture it, somehow Walter Hunt hooked up with a man named Isaac Singer. Hunt was able to make a replica of Howe's sewing machine, and Singer manufactured and sold a lot of sewing machines! (“Singer” is still one of the biggest names in sewing machines.) Since Singer was selling machines with Howe's patented inventions, Howe sued Singer and, after a looooong (6 year) trial, was awarded thousands of dollars in back royalties. Then Howe went on to negotiate getting a five-dollar royalty for each sewing machine manufactured in the U.S. and one dollar for each sold elsewhere. That earned him millions!
