Abstract

Abstract A tire pulverizer adapted to receive and cut automobile, truck or other vehicle tires into small particles, wherein the pulverizer has a plurality of rows of interfitting abrading rotating blades disposed in substantially a V-shape and through which the tires are fed as they are cut into the small particles by the blades.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 315 words
A tire pulverizer for cutting vehicle tires into small particles, comprising: a support frame adapted to be disposed on the ground or other base; said support frame having a first blade support frame and a second blade support frame; said first and second support frames being mounted generally vertically at an acute angle with respect to each other and a vertical axis therebetween and being spaced apart a greater distance and the upper ends thereof than at the lower ends thereof to form an inlet mouth at said upper ends and an outlet discharge at said lower ends; a plurality of rows of adjacent tire cutting and abrading blades mounted on each of said support frames and disposed one above the other at substantially the same generally vertical inclination of each of said first and second support frames; each of said blades having a generally circular periphery and disposed on its shaft for rotation therewith in a generally vertical plane; each of said blades having a cutting edge at its periphery with tungsten carbide or the like hard surfacing material thereon at said periphery for abrading and cutting vehicle tires into small pieces as they fall downwardly between the rows of said blades on said support frames from the uppermost rows through the lowermost rows; means for mounting the blades on the adjacent rows of said blades on said first blade support means so that they interfit with each other; means for mounting the blades on the lowermost row of blades on said first blade support means and the blades on the lowermost row of blades on said second blade support means so that they interfit with each other so as to form a cutting barrier through which the tires must pass to be discharged at the lower ends of said support frames to thereby effect a pulverizing of the tire into very small particles.
Claim 2
Dependent Claim 315 words
A tire pulverizer for cutting vehicle tires into small particles, comprising: a support frame adapted to be disposed on the ground or other base; said support frame having a first blade support frame and a second blade support frame; said first and second support frames being mounted generally vertically at an acute angle with respect to each other and a vertical axis therebetween and being spaced apart a greater distance and the upper ends thereof than at the lower ends thereof to form an inlet mouth at said upper ends and an outlet discharge at said lower ends; a plurality of rows of adjacent tire cutting and abrading blades mounted on each of said support frames and disposed one above the other at substantially the same generally vertical inclination of each of said first and second support frames; each of said blades having a generally circular periphery and disposed on its shaft for rotation therewith in a generally vertical plane; each of said blades having a cutting edge at its periphery with tungsten carbide or the like hard surfacing material thereon at said periphery for abrading and cutting vehicle tires into small pieces as they fall downwardly between the rows of said blades on said support frames from the uppermost rows through the lowermost rows; means for mounting the blades on the adjacent rows of said blades on said first blade support means so that they interfit with each other; means for mounting the blades on the lowermost row of blades on said first blade support means and the blades on the lowermost row of blades on said second blade support means so that they interfit with each other so as to form a cutting barrier through which the tires must pass to be discharged at the lower ends of said support frames to thereby effect a pulverizing of the tire into very small particles.
Claim 3
Dependent Claim 110 words
The structure set forth in claim 1, wherein: said mounting means includes a rotatable shaft for each row of said blades; said shaft for each row of said blades on each of said blade support frames being mounted a predetermined distance from each other; the radial dimension of each blade being approximately the same as said pRedetermined distance; means for holding the blades on adjacent shafts offset with respect to each other for thereby interfitting the blades on the adjacent shafts with each other; and tungsten carbide or the like hard surfacing material on the sides of each of said blades near the periphery thereof for abrading the vehicle tires.
Claim 4
Dependent Claim 80 words
The structure set forth in claim 2 wherein said means for holding said blades offset, comprises: spacers on each shaft and disposed on each side of each blade; and each of said spacers having a thickness approximately equal to but slightly greater than the thickness of each blade to thereby dispose the sides of the interfitting alternate rows of blades in close proximity to each other to control the size of tire particles cut thereby and which may pass therebetween.
Claim 5
Dependent Claim 67 words
The structure set forth in claim 1, including: side housing plates extending substantially vertically on each side of said support frames and in close proximity to the end blade for each row of blades; and said blades on each of said rows extending for substantially the full width between said side housing plates for confining the tires passing between said rows of blades for pulverizing said tires.
Claim 6
Dependent Claim 56 words
The structure set forth in claim 1, including: means for guiding a tire substantially vertically into said inlet mouth between said rows of blades at said mouth, with the external circumference of the tire lying in a plane that substantially bisects the space between said rows of blades on said first and second blade support frames.
Claim 7
Dependent Claim 36 words
The structure set forth in claim 1, including: a discharge chute formed externally of said first and second blade support frames for receiving and discharging the tire particles formed by the tires passing through said blades.
Claim 8
Dependent Claim 23 words
The structure set forth in claim 1, including: means for feeding tires in sequence between said rows of blades at said inlet mouth.
Claim 9
Dependent Claim 27 words
The structure set forth in claim 7, including: means for shifting each tire to an upright substantially vertical position as it is fed to said inlet mouth.
Claim 10
Dependent Claim 33 words
The structure set forth in claim 1, including: means for spraying water or the like onto each tire so as to wet same for facilitating the pulverizing of the tire by said blades.
