This machine, designed by Alton S. Newell, efficiently reduced automobile bodies into scrap metal for recycling. A body was fed into the shredder at a controlled rate, and rotating hammers, driven by a 500-hp motor, shredded it into small pieces that were easily shipped. The process took about 10 minutes a car and used less energy than other shredding and crushing machines.

This pump, designed by Edwin Reynolds (1831-1909) and built by the Edward P. Allis company, is the major component of one of the earliest water-pollution control systems. It was capable of pumping more than a half billion gallons of water a day, the highest-capacity pump in the world when installed. It still is used during the summer to pump water from Lake Michigan into the Milwaukee River upstream of the downtown area. This maintains a current in the lower portion of the river and greatly reduces the concentration of pollutants.
