Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
106 words
A handling device for dismounting and remounting wheels, said device comprising: first and second frame members pivotally interconnected along an axis, said second frame member having means for carrying a wheel such that the wheel axis and the pivot axis interconnecting said frames extend in the same direction and are in substantially vertical alignment; means for pivoting said second frame member back and forth about the pivot axis interconnecting said frames to move the axis of the wheel into and out of vertical alignment with said pivot axis; and means for holding said first frame member to permit said second frame member to pivot relative thereto.
Claim 2
Dependent Claim
106 words
A handling device for dismounting and remounting wheels, said device comprising: first and second frame members pivotally interconnected along an axis, said second frame member having means for carrying a wheel such that the wheel axis and the pivot axis interconnecting said frames extend in the same direction and are in substantially vertical alignment; means for pivoting said second frame member back and forth about the pivot axis interconnecting said frames to move the axis of the wheel into and out of vertical alignment with said pivot axis; and means for holding said first frame member to permit said second frame member to pivot relative thereto.
Claim 3
Dependent Claim
28 words
A device according to claim 1, wherein the second frame comprises two parallel arms, making a fork, extending rearwardly, parallel to the pivotal axis of the two frames.
Claim 4
Dependent Claim
15 words
A device according to claim 2, wherein each of said arms carries a cylindrical roller.
Claim 5
Dependent Claim
17 words
A device according to claim 2, wherein each of said arms carries a train of cylindrical rollers.
