Patent number: 6471148Abstract: A glass smasher is provided of the type for placement of glass articles for reduction to a particle size for reduced volumetric disposal and/or recycling purposes. Recycling may include reforming into another glass product or use as an aggregate. The glass smasher includes a rotatable barrel which may be divided into one or more internal chambers. At least a first chamber is formed having impacting means for breading and article into particles when the barrel is rotated. The first chamber may include free moving or floating smashing members such as ball bearings, bars or the like and/or attached impacting members. When an article of glass is placed in the first chamber and the barrel is rotated the article is broken into particles. These particles may be rotated and continued to impact the members until a desired particle size is achieved.Type: GrantFiled: October 27, 2000Date of Patent: October 29, 2002Assignee: Paisano Industries, L.P.Inventor: John Russell Mase, Jr.
