Abstract
Abstract Foot pads for the stabilizer arms of a back hoe provided with resilient pads of tough wear-resisting material engaging the asphalt or concrete surface of the pavement during use of the back hoe. The tough wear-resistant pads provide support for the stabilizer arms without digging into the pavement surface. The foot pads are pivotally attached to the ends of the stabilizer arms so that the tough resilient pad portions thereof adjust automatically to the contour of the pavement and provide firm footing for the stabilizer arms.

Total Claims: 8
Claim 1
Independent Claim
187 words
In stabilizing supports for back hoes and the like which include arms that are pivotally attached to sides of the back hoe and are adapted to extend from said sides, said back hoe having means for lowering said arms to engage the ground and provide side bracing to the back hoe, the improvement comprising foot pads for each of said arms, means separately pivotally attaching said foot pads to the bottoms of said arms, each of said foot pads comprising resilient members having relatively large substantially flat areas for squarely and firmly engaging the pavement to provide firm support to the back hoe without digging into and damaging said pavement on which said foot pads rest during operation of the back hoe, said attaching means of each of said foot pads including a pair of vertical members, means attaching said vertical members to said resilient members comprising members at least partially embedded in said resilient members, each of said first mentioned attaching means comprising a rod extending between said vertical members pivotally supporting said vertical members of said foot pads on the free ends of said arms.
