Volition Repeating Rifle
In 1848, Walter Hunt developed his lever-action Volition Repeating Rifle. Though not a success, features of Hunt's design formed part of the Lewis Jennings Rifle, which in turn contributed to the Henry breach-loading rifle of 1860. Prized by both sides in the American Civil War, this rifle was a starting point for the Winchester Repeating Arms Co. when it went into production with the first of its now-famous rifles in 1866.
State of Maine Pure Spruce Gum
John Bacon Curtis became the world's first producer of commercially manufactured chewing gum after his experiments with gum from the spruce tree in 1848. Within a year, he was traveling around New England and selling the paper-wrapped sticks of his product, which he called State of Maine Pure Spruce Gum. Curtis broadened his range by the introduction of sweetened paraffin-based gum in 1850, a product that ultimately proved more popular than the spruce-based original.
Gutta Percha Golf Ball
Although the origins of golf lie in Scotland as far back as the 16th century, a major development came in 1848 when the Rev. Adam Paterson developed the Gutta Percha ball. Also known as the guttie, Paterson's invention was a ball made from the rubbery sap of the tropical gutta tree. Subsequent development of the guttie, already cheaper to produce than the earlier feather-packed golf balls, saw the addition of a rough surface that allowed the ball to travel greater distances.
Device to Buoy Vessels over Shoals
In 1848, the boat on which Illinois Congressman Abraham Lincoln was traveling became stuck on shoals in the Detroit River. After he returned to Illinois, he devised a system of inflatable bellows attached to a boat's hull that would enable a grounded vessel to be lifted clear of obstruction and set afloat again. Though the invention never went into production, Lincoln did receive a patent for it in 1849, the only one ever owned by a U.S. president as of 2011.
