Abstract
Abstract A material processing apparatus in which a housing is provided for receiving the material which is transported along the length of the housing to an outlet for discharge. One or more breaker assemblies are supported by the housing and normally extend in the path of the material as it passes from the inlet to the outlet. As the moving material contacts each breaker assembly it is subjected to forces which tend to break up individual material particles and accumulations of particles to prevent a jamming condition. Each breaker assembly includes a rod which is carried in and extends outwardly from the end of an externally threaded sleeve. The rods are retractable from the path in response to a force of predetermined magnitude applied to the rod by the material and is adapted to return to its normal position after release of the force.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
158 words
An apparatus for breaking up material, comprising a housing having an inlet for receiving said material and an outlet for discharging said material, means for feeding the material from said inlet to said outlet and breaking up said material, at least one elongated member supported by said housing and normally extending in the path of said material as it passes from said inlet to said outlet, means associated with said member for applying a predetermined force to said member in a first direction perpendicular to the longitudinal axis of said housing and of a sufficient magnitude to enable said member to inhibit jamming of said material, said force applying means permitting said member to retract from said path in a direction opposite to said first direction in response to a force acting on said member by said material in excess of said predetermined force, and to return to said path after release of said force by said material.
Claim 2
Independent Claim
158 words
An apparatus for breaking up material, comprising a housing having an inlet for receiving said material and an outlet for discharging said material, means for feeding the material from said inlet to said outlet and breaking up said material, at least one elongated member supported by said housing and normally extending in the path of said material as it passes from said inlet to said outlet, means associated with said member for applying a predetermined force to said member in a first direction perpendicular to the longitudinal axis of said housing and of a sufficient magnitude to enable said member to inhibit jamming of said material, said force applying means permitting said member to retract from said path in a direction opposite to said first direction in response to a force acting on said member by said material in excess of said predetermined force, and to return to said path after release of said force by said material.
Claim 3
Dependent Claim
17 words
The apparatus of claim 1, wherein said feeding means comprises an auger rotatably mounted in said housing.
Claim 4
Dependent Claim
51 words
The apparatus of claim 1, wherein said elongated member is in the form of a rod and further comprising an additional housing secured relative to said assembly housing and adapted to receive at least a portion of said rod, and additional housing having an externally threaded portion extending in said path.
Claim 5
Dependent Claim
67 words
The apparatus of claim 1, wherein said force applying means comprises an additional housing, a portion of said elongated member extending within said additional housing and a portion of said elongated member normally projecting from said additional housing, means disposed in said rod housing and normally forcing the projecting portion of said elongated member towards said path while permitting said projecting portion to retract from said path.
Claim 6
Dependent Claim
30 words
The apparatus of claim 4, further comprising means cooperating with said additional housing and said elongated member for varying the amount of said predetermined force applied to said elongated member.
Claim 7
Dependent Claim
32 words
The apparatus of claim 4, further comprising means cooperating with said additional housing and said elongated member for permitting the length of the projecting portion of said elongated member to be varied.
