Thomas Edison apparently after developing several of the electrical devices we use today, such as lights, motor, electrical distribution system, started investing in manufacturing which implemented his inventions.  The text books give him credits on his electrical inventions, but they do not mention much on is other inventions.

He actually invented, along with his electrical motors, and electrical distribution system, many mechanically system used in several industries, especially in quarrying and ore handling.  Also, major advancement in cement manufacturing.

 Thomas Edison started investing and creating a electical magnetic separator to remove iron ore for processing from low grade iron ore quarried material.  This looked promising, but was closed down after high grade ore deposited were found elsewhere, which could be processed at a lower cost.

After this, Thomas started looking at the cement industry.  He was interested in the industry not only for the manufacturing opportunities, but as well for the promise of improving human life from the advancemenet of cement manufacturing.  He invisioned the dirt and stone roads to be replaced with concrete roads.  Also, he invisioned cement being used in building structures.

At this time, the manufacturing of cement was a slow and limited in quantity.  Most cement kilns were vertical kilns which could only produce a ton or two of cement every day or two.  Cement was limited supply.

• Rotary cement kiln
• Material separator
• Apparatus for burning Portland Cement
• Drier
• Apparatus and methods for breaking rocks
• Rock crushing
• Rock grinding
• Screening and sizing fine material
• Grinding rolls
• Cement kiln
• Feed-Regulator for Grinding Machines
• Process and Apparatus for Artificially Aging or Seasoning Portland Cement
• Crushing-Rolls
• Bucket Conveyer
• Crushing and Separating Fine Materials
• Manufacture of Portland CementManufacture of Portland Cement
• Cement-Burning Kiln
• Mold for Concrete Construction
• Means for Utilizing the Waste Heat in Kilns
• Method of Burning Portland-Cement Clinker
• Method of Utilizing Waste Heat in Kilns

This does not include the electrical power equipment patients and inventions that are implement in the cement manufacturing process.

Thomas Edison started using his electrical knowledge and cement manufacturing knowledge to start improving the cities in the east. The cities started installing electrical distribution and electrical apparatus to provide lighting, heating, other electrical amendities that we enjoy.

With these improvement, the streets started being paved with concrete to better lifes of the people. Concrete started being used in construction and buildings.

The previous electrical inventions provided energy and mechanical movers to run his cement equipment, which greatly helped increase the volume of production.

Thomas Edison was one of great people of our times.  His inventions improved the lifes of billions.  He holds a large number patents and has inventory an extra-ordinary amount of inventions.  He invested into the country and used his inventions to improve the world.
