On January 30 James Ritty and John Birch received U.S. Patent No. 271,363 on a Cash Register

James Ritty was a saloon keeper concerned that some of his some of his employees were skimming customers’ money meant to pay for food and drink. On a cruise he noticed a machine that counted rotations of the ship’s propeller, and thought something similar could be used to track cash transactions back at his saloon.

James enlisted the help of his brother John, a skilled mechanic, and the brothers began working on a design for such a device. After several failed prototypes, they created their third design, operated by pressing a key that represented a specific amount of money. There was no cash drawer. James and John Ritty patented the design on November 4, 1879, as “Ritty’s Incorruptible Cashier”:

The Rittys opened a small factory to make cash registers while continuing to operate the saloon. The company was not prospering and James Ritty his interest in the cash register business to a group of investors who formed the National Manufacturing Company, which was eventually renamed the National Cash register Company.

On January 29, 1924, Carl R. Taylor received U.S. Patent No. 1,481,813 on an [Ice Cream] Cone Rolling Machine:

Carl allegedly attended the 1904 World’s Fair in St. Louis, where he became fascinated with ice cream and the ice cream cone. He returned to Cleveland and spent nearly two decades developing a machine to quickly and cheaply make ice cream cones. Although his was not the first cone rolling machine (that honor goes to H.G. Tatosian’s U.S. Patent No. 1,440,851, issued January 2, 1923, which was filed just five days before Carl’s filing date):

Shortly after his patent issued, Carl formed the Ice Cream Cone Company to manufacture the cones. Eventually the Ice Cream Cone Company was acquired by Norse Dairy Systems.

On January 26, 1875, George F. Green received U.S. Patent No. 159028 on an Electro-Magnetic Dental Tool (drill):

On January 25, 1870, Gustavus Dows received U.S. Patent No. 99170 on a Soda Fountain:

Gustavus D. Dows, the youngest of a 21-child family from Billerica, ran a drugstore with his brother at 213 Central Street in Lowell in the mid-1850s. He spent his days serving shaved ice lemonade to his customers, laboriously pulling a block of ice from an ice box each time and set to shaving with a hand planer it to make each drink. He spent his nights trying to come with a better way to make his shaved ice drinks, eventually inventing a dispenser that shaved ice and then automatically mixed it with syrup and cream.

Dows patented his invention and moved to Boston’s Washington Street, where business boomed. Not only did he sell more and more ice cream sodas, but he also sold his patented soda fountains. The New York Times wrote that Mr. Dows was the first to create a fountain that “looked like a Doric temple.”

On January 24, 1871, Charles Goodyear, Jr., (son of the inventor of vulcanization of rubber) received U.S. Patent No. 111,197 on a Machine for Sewing Boots and Shoes:

A welt is a strip of material (e.g., leather, rubber, or plastic) extending the perimeter of a shoe outsole.

On January 23, 1968, U.S. Patent No. 3,364,616, issued to Samuel Speers on a Toy Deep Sea Diver Outfit:

In 1969 after several hits including GI Joe and Mr. Potatohead, Hassenfeld Brothers rebranded as Hasbro, and Speers was an integral part of their success.

On January 19, 1904, Charles Foglesong received U.S. Patent No. 750179 on an ELectric Blanket:
