Abstract

A ladder type framework is removably supported on the open rim of a pipe embedded upright in the ground and extending therefrom. The frame has a plurality of spaced cross-members supported in generally horizontal position. A tube, cable, line, and the like, is supported on a selected cross-member of the frame in spaced relation with the rim of the pipe to permit such tube, cable, line, and the like, to be raised and lowered in the pipe spaced from the rim to prevent abrasion by the rim.

Claims

1. A tool for selectively raising and lowering submersible pumps without snags in a pipe embedded substantially upright in the ground, said pipe having an open end above the ground with a rim therearound, said tool comprising

a first pair of rail-type support members;

first cross-members affixed to and extending substantially perpendicularly between the first pair of members in spaced relation and supporting said support members in spaced substantially parallel relation;

bracket means comprising a pair of inverted substantially L-shaped brackets affixed to the support members for mounting said support members on the pipe at the open end thereof, said support members extending substantially parallel to the axis of the pipe so that the cross-members extend coplanarly in a first plane, the first plane being substantially parallel to said axis, said first cross-members extending substantially perpendicularly to said axis;

a second pair of rail-type mounting members each affixed to a corresponding one of the support members at an upwardly opening acute angle therewith, said mounting members extending coplanarly in a second plane at an angle with the first plane, said mounting members being affixed to said support members at a predetermined distance from the bracket means whereby said mounting members are spaced from the rim of the pipe; and

second cross-members affixed to and extending substantially perpendicularly between the second pair of members in spaced relation coplanarly in the second plane, said second cross-members extending substantially perpendicularly to the axis of the pipe for supporting a tube, cable, line, and the like, in spaced relation with the rim of the pipe to permit said tube, cable, line, and the like, to be raised and lowered in the pipe spaced from said rim to prevent abrasion by said rim, said tube, cable, line, and the like, extending out of said pipe, passing over one of the first cross-members between the first support members, over one of the second cross-members farther above the rim of said pipe than said one of said first cross-members and under another of said second cross-members farther above said rim of said pipe than said one of said second cross members.
