History 5, Lesson 90

Summarize each of the inventions you studied this week and how they impacted history. Also, explain the most interesting thing you learned this week, and why. Well this week in history I learned about a lot of cool inventions. 

               A british comedian played a joke in 1810. The postcard concept appeared in 1861 in the U.S. John P. Charlton patented the idea. He had help from Hymen Lipman, inventor of pencil eraser. The postcard is simple and useful. Front-and-back rectangular card. Send cheap messages.

                  Richard Gatling was born in North Carolina in 1818. He was a store owner, doctor, and inventor. The civil war provided his source of inspiration. He wanted to save lives by reducing soldiers needed on the battlefield. He invented the Gatling Gun in 1861. 

                Frederick Walton was born in England in 1834. He noticed that linseed oil dried into a rubbery consistency. Walton Experimented with drying the linseed oil faster than normal. He patented linoleum in 1863. Walton had trouble generating sales initially. He had developed marketing to overcome his competition. Cheap imitators appeared by 1871. 

                 The socket was not brand new in the 1800s. Ancient cultures used sockets to fasten tools together. The first wrench was patented in 1835. J.J. Richardes patented the Ratcheting Wrench in 1863. The ratchet only allows motion in one direction. Socket heads plug into cylinders.

                    I think the most interesting invention is the Gatling Gun. I find it cool that he wanted to help save lives on the battlefield. It’s Also the start of turits. I think it is cool also because it is a big gun. 

                      That is what I learned in history this week. They were all really cool but the gatling gun is the coolest.
