Abstract

Abstract A method for cryogenically treating automotive tires is disclosed which includes chopping substantially whole tires into segments so as to assure drainage of the cryogen from the tire after treatment. There is also disclosed a truck mounted apparatus for chopping the whole tires, or coiled materials, into segments. The apparatus is mounted to the bed of a truck and includes a delivery conveyor for moving the tire or coil to a pair of hydraulically-operated shears which are mounted on the bed for chopping the tire, or coil, into two segments. The delivery conveyor and shears are synchronized so that each tire or coil is delivered to the shear, the conveyor is stopped, the shears are activated, the tire or coil is chopped, the conveyor is restarted and the tire or coil segments are then discharged from the shear. The discharged segments drop onto a discharge conveyor which transports the segments to a station for secondary treatment.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 173 words
A mobile material-chopping apparatus, for chopping substantially ring-shaped bodies into segments, which includes: an elongated movable bed; shear means which include movable cutting jaws for chopping the body delivered thereto into segments; delivery conveyor means cooperatively arranged with respect to said bed and said shear means for moving the bodies from a loading position to said shear means; and means for actuating said shear means so as to chop said body, wherein said shear means include cutting means which move in a substantially vertical plane which is parallel to the longitudinal axis of said bed; and wherein said cutting means include two aligned shears each including a stationary lower jaw and a movable upper jaw pivotally mounted for shearing cooperation with said lower jaw, and the shears being spaced from each other by a distance sufficient to permit at least a portion of said delivery conveyor to fit therebetween, so as to deliver said ring-shaped body to a chopping position between the upper and lower jaws of each shear for chopping into segments.
Claim 2
Dependent Claim 173 words
A mobile material-chopping apparatus, for chopping substantially ring-shaped bodies into segments, which includes: an elongated movable bed; shear means which include movable cutting jaws for chopping the body delivered thereto into segments; delivery conveyor means cooperatively arranged with respect to said bed and said shear means for moving the bodies from a loading position to said shear means; and means for actuating said shear means so as to chop said body, wherein said shear means include cutting means which move in a substantially vertical plane which is parallel to the longitudinal axis of said bed; and wherein said cutting means include two aligned shears each including a stationary lower jaw and a movable upper jaw pivotally mounted for shearing cooperation with said lower jaw, and the shears being spaced from each other by a distance sufficient to permit at least a portion of said delivery conveyor to fit therebetween, so as to deliver said ring-shaped body to a chopping position between the upper and lower jaws of each shear for chopping into segments.
Claim 3
Dependent Claim 33 words
A material-chopping apparatus as in claim 1 wherein, in the conveying position, the delivery conveyor moves said bodies across the bed in a lateral direction transverse to the longitudinal axis of the bed.
