Abstract: A jackscrew insert and a method for jackscrew insertion into existing mounting openings in a machine base are described. A jacking shoulder is provided by a modification of the existing mounting openings utilizing a jackscrew machining tool. The jackscrew machining tool includes a cutting edge which cuts the jacking shoulder into the machine base adjacent the existing mounting openings. Should the existing mounting openings not be modified for proper utilization of the jackscrew insert, a jackscrew assembly and method for use are also described.

Abstract: A motor has a shell formed to include an edge defining an opening that is either U-shaped or rectangular. A reversible apparatus has segments for mounting an overload protector having first and second body portions within the opening in the motor shell. The apparatus has a first profile for mounting the overload protector within a U-shaped opening in a motor shell so as to restrict movement of the mounting apparatus and overload protector assembly relative to the motor shell, and a second profile for mounting the overload protector within a rectangular opening in a motor shell so as to restrict movement of the mounting apparatus and overload protector assembly relative to the motor shell.

Abstract: A terminal box for an electric motor has a base and a cover. The base has a curved bottom which conforms to the curve of a cylindrical shell or housing of the motor. The base has first and second portions to which a conduit can be attached which are at angles to each other. The base can be rotated 180.degree. between two positions on the motor housing. A conduit can thus be run to the terminal box from any of four directions. The base is formed such that the first and second portions to which the conduit can be attached are relatively unobstructed when the cover is off. This permits wire to be pulled from the conduit through the terminal box in a relatively unobstructed path. That is, the path of the wire pull need not be angled to avoid an obstructing sidewall.In an embodiment, the base has first and second adjacent sidewalls opposed by third and fourth sidewalls, respectively. The first and second sidewalls are relatively higher than their respective opposed third and fourth sidewalls.
