An electrical connector for supplying electrical power to a machine at particular voltage and phase magnitudes selected, the connector having one part adapted to be mechanically and electrically connected to the machine and another part adapted to be electrically connected to a conductor providing the electrical power to be supplied. The connector comprises a plurality of pins on one of the connector parts and a corresponding plurality of mating slots on the other of the connector parts adapted to receive the pins when the connector parts are connected together. One of the pins and the corresponding one of the mating slots serve to complete an electrical ground circuit and have a fixed orientation independent of the selected voltage and phase magnitude for the particular connector. The remaining ones of the pins and slots are of a total number and have respective orientations unique to the particular voltage and phase magnitude selected for the connector, and the total number and orientations of the remaining pins and slots are fixed and non-changeable. In a method for forming the connector part having the slots, a hollow body is formed to have an end face and to include the one slot in the end face, and subsequently the remaining slots are provided such as by stamping in the end face spaced from the one slot and being of a number and having orientations selected according to the voltage and phase magnitudes for the particular connector.

A cloth spreading apparatus for spreading superimposed layers of cloth on a plurality of tables which are connected together side-by-side, the superimposed layers of cloth being in correct alignment with each other. The apparatus includes a cloth laying machine supported on the working surface of the tables for side-to-side traversing movement. As the machine moves from side to side, it will deposit a plurality of superimposed layers of cloth on the tables. The cloth laying machine includes a frame having a front portion normally disposed adjacent a front edge of the tables. The apparatus further includes guide means for guiding the cloth laying machine. The guide means includes a plurality of cylindrical rods, dowels which align the guide rods in end-to-end relationship, and a rail assembly which is rigidly interconnected with the guide rods and with front legs of the tables. The guide means additionally includes a pair of spaced apart horizontally disposed linear bearings mounted on the guide rods and support means interconnecting the bearings with the front portion of the frame of the cloth laying machine.

The total number and orientations of the remaining ones of the pins and slots also are selected to prevent connection between either of the connector parts and a part of another connector of the same type as the connector but operative with different selected voltage and phase magnitudes.

Electrical connector

A punching machine comprising a housing, a plunger having a punch at one end, and an electromechanical drive such as a solenoid carried by the housing and operatively connected to the plunger for driving the plunger in a direction along the longitudinal axis thereof when electrically energized to drive the punch into a workpiece and then withdraw the punch therefrom. The plunger is disposed in a housing passage in a manner permitting a degree of rocking movement of the plunger in a plane substantially parallel to the plunger longitudinal axis. A flexible guiding device in the form of a sleeve surrounding the plunger and an O-ring engaging the sleeve and the housing guides the plunger in a direction toward and away from the workpiece and also in the direction of the rocking movement. Electric current is supplied to the electromechanical drive by a circuit including a controlled rectifier connected in controlling relation to the drive and having a gate terminal connected to trigger pulse producing device. The trigger pulse producing device, in turn, is operated by a control circuit in response to control inputs, for example repetitively in response to movement of the machine along the workpiece or, alternatively, singly for only one punching in response to another control input.
