Abstract

Abstract A tire cutter apparatus for cutting a strip of a crown of a tire or splitting a tire circumferentially including a fixed rotating knife or knives in contact therewith during a cutting operation. Rotation of cutter as well as the power required to lift the tire into cutting contact therewith is provided by a hydraulic system having a flow divider which supplies power to an orbital motor to drive the blades and to a hydraulic cylinder which raises and lowers the tire supporting mandrel.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 128 words
A tire cutting apparatus comprising frame means, cutting means having at least one rotatably mounted cutting element supported on the frame means, motor means operatively coupled to the cutting element to cut a tire in contact therewith, mandrel means mounted on the frame means and adapted to support a tire to be cut, power means supported on the frame means for producing relative movement between the cutting means and the mandrel to effect operative contact therebetween for cutting a tire, positioning means operatively coupled to the frame means adjacent the cutter element for maintaining positive operative contact between the tire and cutting means during cutting, and pivotal guard means mounted on said cutting means and being movable away from said cutter in response to contact by the tire.
Claim 2
Dependent Claim 128 words
A tire cutting apparatus comprising frame means, cutting means having at least one rotatably mounted cutting element supported on the frame means, motor means operatively coupled to the cutting element to cut a tire in contact therewith, mandrel means mounted on the frame means and adapted to support a tire to be cut, power means supported on the frame means for producing relative movement between the cutting means and the mandrel to effect operative contact therebetween for cutting a tire, positioning means operatively coupled to the frame means adjacent the cutter element for maintaining positive operative contact between the tire and cutting means during cutting, and pivotal guard means mounted on said cutting means and being movable away from said cutter in response to contact by the tire.
Claim 3
Dependent Claim 189 words
A tire cutting apparatus comprising frame means, cutting means having at least one rotatably mounted cutting element supported on the frame means, motor means operatively coupled to the cutting element to rotate the cutting element and cut a tire in contact therewith, mandrel means adapted to support a tire to be cut, said mandrel means movably supported on the frame means between a first position and a second position adjacent the cutter element, power means operatively connected to the mandrel means to move the mandrel means either from the first position to the second position to cause a tire supported thereon to contact the cutting element or from the second position to the first position to remove a tire from contact with the cutting element, guard means positioned adjacent the cutting means for covering the cutting element when a tire is not in contact with the cutting element and for moving away from the cutting element to permit contact between the tire and the cutting element and positioning means being biased to guide a tire between said first and second positions and maintain alignment of a tire during cutting.
Claim 4
Dependent Claim 189 words
A tire cutting apparatus comprising frame means, cutting means having at least one rotatably mounted cutting element supported on the frame means, motor means operatively coupled to the cutting element to rotate the cutting element and cut a tire in contact therewith, mandrel means adapted to support a tire to be cut, said mandrel means movably supported on the frame means between a first position and a second position adjacent the cutter element, power means operatively connected to the mandrel means to move the mandrel means either from the first position to the second position to cause a tire supported thereon to contact the cutting element or from the second position to the first position to remove a tire from contact with the cutting element, guard means positioned adjacent the cutting means for covering the cutting element when a tire is not in contact with the cutting element and for moving away from the cutting element to permit contact between the tire and the cutting element and positioning means being biased to guide a tire between said first and second positions and maintain alignment of a tire during cutting.
Claim 5
Dependent Claim 17 words
The tire cutter of claim 2 wherein the guard means is pivotally mounted on the cutting means.
Claim 6
Dependent Claim 27 words
The tire cutter of claim 2 wherein the grard means includes a roller to permit relative movement between the guard means and a tire in contact therewith.
Claim 7
Dependent Claim 144 words
A tire cutting apparatus comprising frame means, cutting means having at least one rotatably mounted cutting element supported on the frame means, motor means operatively coupled to the cutting element to cut a tire in contact therewith, mandrel means mounted on the frame means and adapted to support a tire to be cut, power means supported on the frame means for producing movement Of the mandrel upward to contact the cutting element to effect operative contact therebetween for cutting a tire, positioning means operatively coupled to the frame means adjacent the cutter element for maintaining positive operative contact between the tire and cutting means during cutting, and said positioning means being resiliently biased in position substantially between the cutting element and the mandrel and mounted for movement away from the cutter in response to upward movement of a tire to contact the cutting element.
Claim 8
Dependent Claim 144 words
A tire cutting apparatus comprising frame means, cutting means having at least one rotatably mounted cutting element supported on the frame means, motor means operatively coupled to the cutting element to cut a tire in contact therewith, mandrel means mounted on the frame means and adapted to support a tire to be cut, power means supported on the frame means for producing movement Of the mandrel upward to contact the cutting element to effect operative contact therebetween for cutting a tire, positioning means operatively coupled to the frame means adjacent the cutter element for maintaining positive operative contact between the tire and cutting means during cutting, and said positioning means being resiliently biased in position substantially between the cutting element and the mandrel and mounted for movement away from the cutter in response to upward movement of a tire to contact the cutting element.
Claim 9
Dependent Claim 17 words
The tire cutter apparatus of claim 5 wherein the positioning means is pivotally attached to the frame.
Claim 10
Dependent Claim 18 words
The tire cutting apparatus of claim 5 wherein the motor means and the power means are fluid operated.
Claim 11
Dependent Claim 23 words
The tire cutting apparatus of claim 7 wherein the motor means and power means are coupled to a common source of pressurized fluid.
Claim 12
Dependent Claim 54 words
The tire cutting apparatus of claim 8 wherein the source of pressurized fluid includes a hydraulic pump for providing pressurized fluid, conduit means coupled to the pump and said conduit means including a flow divider for supplying a portion of pressurized fluid to the motor means and the remaining portion to the power means.
Claim 13
Dependent Claim 32 words
The tire cutting apparatus of claim 8 further including safety cut off means interposed between the source of pressurized fluid and the motor means to selectively discontinue operation of the motor means.
Claim 14
Dependent Claim 22 words
The tire cutting apparatus of claim 10 wherein the safety cut off means includes an actuation element positioned adjacent the cutting element.
Claim 15
Dependent Claim 23 words
