Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
158 words
A reinforced elastic boot of tubular form adapted to be connected in airtight engagement between relatively movable members to absorb the shock of one of said members with respect to the other of said members in the direction of the axis of said boot, said boot comprising a reinforcing net having little inherent elasticity and provided with openings therein, said net being formed into a tube; said net encased in elastic material uniformly coating both sides of the net and extending across and closing said openings in the net; said tubular net capable of only slight transverse expansion and said openings being of such size as to allow said elastic material covering said openings to bulge outwardly beyond said net when the boot is at least partially inflated and pressure is applied to move one of said members toward the other of said members whereby said boot cushions the movement between said members without substantial loss of shape.
Claim 2
Dependent Claim
158 words
