Albert Richardson was one of those rare inventors who not only created numerous devices, but created devices that were completely unrelated to one another.
Until 1891 anyone wanting to make butter would have to do so by hand in a bowl. On February 17, 1891 Richardson patented the butter churn. The device consisted of a large wooden cylinder container with a plunger-like handle which moved up and down. In doing so, the movement caused oily parts of cream or milk to become separated from the more watery parts. This allowed for an easy way to make butter and forever changed the food industry.
In 1894, Richardson saw a problem with the way the bodies of dead people were buried. It was common at that time to simply bury bodies in small, shallow graves or to try to lower their caskets with ropes into a deeper hole. Unfortunately, this required several people to work in unison to ensure that the casket was lowered evenly. Failure to do so could cause the casket to slip out of one of the ropes and to be damaged from hitting the ground.
On November 13, 1894, Richardson patented the casket lowering device which consisted of a series of pulleys and ropes or cloths which ensured uniformity in the lowering process. This invention was very significant at that time and is used in all cemeteries today.
In addition to these devices, Richardson patented a hame fastener in 1882, an insect destroyer in February of 1899 and an improvement in the design of the bottle in December of 1899.
