Claim 4

A bay for an electrical control center the combination comprising: a vertical wiring trough extending along the front and at one side of the interior of the bay, such trough being partially defined by a vertical web pierced by a column of vertically spaced openings, which openings present wiring access from the trough into the interior proper of the bay; shelf supports rising vertically along the interior side of the bay that are opposite said vertical web; a plurality of removable, horizontal shelves in said bay each supported at one end by said shelf supports and at the other end by insertion into one of said vertically spaced openings of said vertical web; a plurality of control assembly cabinets each slidable upon a shelf to a housed position within the bay; and each cabinet having a side wall alongside said vertical web of said vertical wiring trough that extends for a part only of the height of said cabinet to define a set back along its side adjacent said vertical wiring trough which extends along the full depth of the cabinet to have a space between the cabinet and wiring trough that is not intersected by the cabinet when the cabinet is mounted and removed from the bay, the set back of the cabinet having an opening which communicates with an opening in said vertical web, and which also opens upon the interior of the cabinet to thereby provide a space between the opening and the cabinet into which wiring that normally extends into the cabinet can be diverted, so when the cabinet is slid into and out of the bay wiring is bypassed by the cabinet.

Claim 5

A bay for an electrical control center the combination comprising: a vertical wiring trough extending along the front and at one side of the interior of the bay, such trough being partially defined by a vertical web pierced by a column of vertically spaced openings, which openings present wiring access from the trough into the interior proper of the bay; shelf supports rising vertically along the interior side of the bay that are opposite said vertical web; a plurality of removable, horizontal shelves in said bay each supported at one end by said shelf supports and at the other end by insertion into one of said vertically spaced openings of said vertical web; a plurality of control assembly cabinets each slidable upon a shelf to a housed position within the bay; and each cabinet having a side wall alongside said vertical web of said vertical wiring trough that extends for a part only of the height of said cabinet to define a set back along its side adjacent said vertical wiring trough which extends along the full depth of the cabinet to have a space between the cabinet and wiring trough that is not intersected by the cabinet when the cabinet is mounted and removed from the bay, the set back of the cabinet having an opening which communicates with an opening in said vertical web, and which also opens upon the interior of the cabinet to thereby provide a space between the opening and the cabinet into which wiring that normally extends into the cabinet can be diverted, so when the cabinet is slid into and out of the bay wiring is bypassed by the cabinet.

Claim 6

An apparatus as in claim 3, wherein each shelf has a rear stop and a forward turned edge; and each cabinet has a latch member at its forward end that engages with said shelf edge.

Claim 7

A bay for an electrical control center the combination comprising: power distributing buses within the bay that are set back from the front of the bay; a vertically extending web within and at the front of said bay which defines a vertical wiring trough disposed along the front and one side of the interior of the bay, said web having a plurality of vertically spaced openings along its length which provide access from the trough into the interior proper of the bay; a trough door at the front of the bay enclosing said vertical wiring trough along the front thereof, and exposing the trough along its length when opened; shelf supports rising vertically along the interior of the side of the bay that are opposite said vertically extending web; a pluraLity of removable, horizontal shelves in said bay each supported between said shelf supports and said vertical web, each shelf having a downturned front edge with at least one slot adjacent the edge, a rear stop, and fore and aft extending cabinet guides; a plurality of control assembly cabinets each slidable upon a shelf to a housed position within said bay, the movement of a cabinet into housed position being guided by said cabinet guides of its associated shelf and limited by the rear shelf stop, each cabinet having: lower and upper latch tongues pivotally mounted at the front of the cabinet for swinging movement in a vertical plane, which tongues of a cabinet being pivotable downward into a slot in the shelf upon which the cabinet rests and upward behind a turned edge of a shelf above the cabinet; screw means in threaded engagement with said latch tongues for moving the latch tongues fore and aft to tighten the tongues against shelf surfaces, and to move the cabinet against the associated rear shelf stop; stab-type connectors at the back of the cabinet connectable with said power distributing buses; and a set back along its side adjacent said vertical wiring trough, so when the cabinet is slid into and out of the bay the region of the set back is not intersected by the cabinet; and a plurality of cabinet doors at the front of the bay that expose the cabinets when opened.

Claim 8

A bay for an electrical control center the combination comprising: power distributing buses within the bay that are set back from the front of the bay; a vertically extending web within and at the front of said bay which defines a vertical wiring trough disposed along the front and one side of the interior of the bay, said web having a plurality of vertically spaced openings along its length which provide access from the trough into the interior proper of the bay; a trough door at the front of the bay enclosing said vertical wiring trough along the front thereof, and exposing the trough along its length when opened; shelf supports rising vertically along the interior of the side of the bay that are opposite said vertically extending web; a pluraLity of removable, horizontal shelves in said bay each supported between said shelf supports and said vertical web, each shelf having a downturned front edge with at least one slot adjacent the edge, a rear stop, and fore and aft extending cabinet guides; a plurality of control assembly cabinets each slidable upon a shelf to a housed position within said bay, the movement of a cabinet into housed position being guided by said cabinet guides of its associated shelf and limited by the rear shelf stop, each cabinet having: lower and upper latch tongues pivotally mounted at the front of the cabinet for swinging movement in a vertical plane, which tongues of a cabinet being pivotable downward into a slot in the shelf upon which the cabinet rests and upward behind a turned edge of a shelf above the cabinet; screw means in threaded engagement with said latch tongues for moving the latch tongues fore and aft to tighten the tongues against shelf surfaces, and to move the cabinet against the associated rear shelf stop; stab-type connectors at the back of the cabinet connectable with said power distributing buses; and a set back along its side adjacent said vertical wiring trough, so when the cabinet is slid into and out of the bay the region of the set back is not intersected by the cabinet; and a plurality of cabinet doors at the front of the bay that expose the cabinets when opened.

Claim 9

A bay for an electrical control center the combination comprising: a vertical wiring trough disposed along the front and at one side of the interior of the bay, such trough being partially defined by a vertical web having a plurality of vertically spaced openings which present wiring access from the trough into the interior proper of the bay; shelf supports spaced vertically along the interior of the bay at a distance from said vertical wiring trough; a plurality of removable, horizontal shelves in said bay each supported between said shelf supports and an opening in said vertical web, each shelf having a downturned front edge and a rear stop; a plurality of control assembly cabinets each slidable upon one of said shelves to a housed position within the bay, the movement of a cabinet being limited by the rear stop of the associated shelf upon which it rests; and each cabinet having lower and upper latch members turnable into engagement with the edges of the shelves above and below the cabinet to secure the cabinet in place, each latch member having a channel shaped bracket; an adjustment screw in said bracket, a latch tongue threaded on said screw for movement along the screw, and a bias spring working against said latch tongue.
