Abstract
Abstract A crusher for articles, such as bottles and cans, having a crushing chamber with a top loading opening communicating with a loading chute having baffles for orienting articles entering the crushing chamber and preventing splashback of liquids or kick-back of articles during crushing, a hydraulically-powered piston movable into the crushing chamber to press articles against a fixed end wall of the chamber and a bottom opening in the chamber for gravity drop of crushed articles from the crushing chamber, with an expansion section of the crushing chamber overlying the bottom discharge opening to prevent binding of the crushed articles within the chamber and permit their fall by gravity through the bottom opening.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
175 words
A crusher for articles such as bottles and cans including a crushing chamber with fixed side walls and a fixed end wall, a loading chute above and opening to said chamber, a crushing piston at the level of said chamber and mounted for movement into said chamber toward said end wall, said piston having a working face with a width substantially equal to the space between the chamber side walls and a height substantially equal to the height of said crushing chamber and a rectangular top plate extending rearwardly from the top of said working face for closing off said loading chute as the piston advances to prevent articles falling behind the piston, said chamber having a bottom opening adjacent said chamber end wall for gravity drop of crushed articles, and said fixed side walls being at an increased distance apart adjacent said end wall throughout the entire height of the crushing chamber and above said bottom opening to define an expansion section of the chamber to free the crushed articles for said gravity drop.
Claim 2
Dependent Claim
175 words
A crusher for articles such as bottles and cans including a crushing chamber with fixed side walls and a fixed end wall, a loading chute above and opening to said chamber, a crushing piston at the level of said chamber and mounted for movement into said chamber toward said end wall, said piston having a working face with a width substantially equal to the space between the chamber side walls and a height substantially equal to the height of said crushing chamber and a rectangular top plate extending rearwardly from the top of said working face for closing off said loading chute as the piston advances to prevent articles falling behind the piston, said chamber having a bottom opening adjacent said chamber end wall for gravity drop of crushed articles, and said fixed side walls being at an increased distance apart adjacent said end wall throughout the entire height of the crushing chamber and above said bottom opening to define an expansion section of the chamber to free the crushed articles for said gravity drop.
Claim 3
Dependent Claim
91 words
A crusher as defined in claim 1 wherein said chamber has a bottom wall with said bottom opening, said bottom wall having a centrally disposed trough extending longitudinally thereof with upwardly inclined sections to either side thereof to facilitate orientation of articles in said chamber as they fall from said loading chute, and said loading chute having a plurality of inclined baffle plates with free edges parallel to said centrally disposed trough for orienting articles for lengthwise positioning in said chamber and preventing upward passage of liquid or articles during crushing.
