Abstract
Abstract A batting practice device is disclosed which has an open ended cylinder of reinforced rubber-like material of at least two plys and weighing at least ten pounds per foot. The cylinders being suspended by a sling of not less than three cables, terminating in a loop at an upper end portion for tying to an overhead support. The loop at the top is formed by bending the cables into an eye shape, and clamping the same. The cylinder is supported by means of apertures near its upper end, the lower end of the sling being secured therein and clamped in place.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
114 words
A batting practice device comprising, in combination, an open ended hollow cylinder, said cylinder being formed of an elastomeric material, a sling for said cylinder, said sling including at least three support members, support means for securing said support members at a position above the cylinder for swingably supporting said cylinder above a surface, said cylinder having the properties of resilience and resistance to deformation under the blow of a bat to simulate the striking of a ball with a bat similar to a reinforced rubber tube of at least two plies and weighing at least ten pounds per foot, whereby a batter can practice repetitive swing at a strike area on said cylinder.
Claim 2
Dependent Claim
114 words
A batting practice device comprising, in combination, an open ended hollow cylinder, said cylinder being formed of an elastomeric material, a sling for said cylinder, said sling including at least three support members, support means for securing said support members at a position above the cylinder for swingably supporting said cylinder above a surface, said cylinder having the properties of resilience and resistance to deformation under the blow of a bat to simulate the striking of a ball with a bat similar to a reinforced rubber tube of at least two plies and weighing at least ten pounds per foot, whereby a batter can practice repetitive swing at a strike area on said cylinder.
