A Short Ancient History of Caster

A Short Ancient History of Caster Casters are one of those things we take for granted and use every day. From the grocery cart to the office chair you sit in, the caster is a part of moving heavy items easily in multiple directions by pushing or pulling. It has become universal in application regardless of culture. It operates to simple mechanical principles, is easy to produce and use, and is now made in thousands of varieties. There has been a bit of debate about how long casters have been around. Some say they were part of material handling as long ago as Ancient Egypt, others point to the patent applied for by David Fisher in 1876. I would volunteer both are correct. Like a lot of industrial product names and descriptions, the word caster covers a lot of ground. The word caster is not unlike the word Hinge. Both can be used as a noun or a verb depending on context. When we think of a fisherman as a caster, we think of him throwing a line. When we think of an aluminum caster, we could be describing the material of a caster wheel, or an object made of aluminum through the hot metal casting process. Go to Websters dictionary and the word caster in the context of wheels is the third entry! In its most direct description with respect to the wheel the word caster describes the use of an integrated frame and axle holding a wheel. This [caster" could be made as a separate sub assembly and be attached to a cart or wagon using any one of a few methods. Early casters that were used by the Egyp
