Abstract

This describes the use of a rubber (or other material having a substantial coefficient of friction) handle or tools used at right angles in limited access areas. Large, slip-over handles or extenders that slip over wrench handles are well known and called torque multipliers. These well known devices, however, cannot be used in limited spaces.

Torque Multipliers for Limited Working Space

This describes the use of a rubber (or other material having a substantial coefficient of friction) handle or tools used at right angles in limited access areas. Large, slip-over handles or extenders that slip over wrench handles are well known and called torque multipliers. These well known devices, however, cannot be used in limited spaces.

An example of such spaces is an adjustment screw or nut in a machine crowded with parts such that the screw or nut can be reached only with the arm fully extended and the available clearance is very limited. The use of a short socket driver with a knurled handle proved helpful but insufficient torque could be applied.

The knurled handle was replaced with a short, wide rubber handle as shown in the figure. The rubber allows the operator to grasp the handle with maximum strength without any discomfort, and the pliability of the handle effectively allows finger-tip force to be translated into the necessary torque. The diameter of the handle depends on the maximum space available in the areas where it is to be used.

Useful sources for suitable handles are paper transport rollers which already include a flange with a set screw.
