Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
161 words
A transporting device for a raw pneumatic tire, especially a belted raw tire, for transporting a raw tire in a substantially horizontal position from a bead-pressing apparatus to a tireheating press, which includes: forked frame means, two pairs of pivotable arms supported by said frame means and respectively pivotally connected to diametrically oppositely located portions of said frame means horizontally of said tire, each arm of each of said pairs of arms having its free end provided with gripper means including angle-shaped holding means with one leg of said angle-shaped holding means for engagement with a shoulder area of the tire to be transported and with the other leg of said angleshaped holding means for engagement with a circumferential area of said tire, and control means associated exclusively with said pairs of arms for selectively freely pivoting the arms of each pair toward and away from each other for adjustment thereof and arresting said arms in their respective desired pivoted position.
Claim 2
Dependent Claim
161 words
A transporting device for a raw pneumatic tire, especially a belted raw tire, for transporting a raw tire in a substantially horizontal position from a bead-pressing apparatus to a tireheating press, which includes: forked frame means, two pairs of pivotable arms supported by said frame means and respectively pivotally connected to diametrically oppositely located portions of said frame means horizontally of said tire, each arm of each of said pairs of arms having its free end provided with gripper means including angle-shaped holding means with one leg of said angle-shaped holding means for engagement with a shoulder area of the tire to be transported and with the other leg of said angleshaped holding means for engagement with a circumferential area of said tire, and control means associated exclusively with said pairs of arms for selectively freely pivoting the arms of each pair toward and away from each other for adjustment thereof and arresting said arms in their respective desired pivoted position.
Claim 3
Dependent Claim
38 words
A transporting device according to claim 1, in which said control means includes a pivoting mechanism operable to exert in four locations substantially the same nominal clamping pressure simultaneously upon all of said gripper means precluding tire deformation.
Claim 4
Dependent Claim
49 words
A transporting device according to claim 2, in which said control means includes a single double-acting pivoting mechanism for pivoting the arms relative to said frame means only of the respective pair of pivotable arms while said gripper means on the free ends of said arms are pivotable individually.
