Claim 3

A cabinet as defined in claim 1 in which each of said sideplates has an inwardly turned rib at each vertical edge and each of said sill and header members has an inwardly turned rib at its outer edge, with said ribs forming a rim about the front opening and about the rear opening.

Claim 4

A cabinet as defined in claim 1 including: a plurality of bus insulator blocks; a pair of elongated block support plates; first connector means fastening each of said bus insulator blocks between said pair of block support plates in vertical spaced relation; a plurality of vertically disposed bus bars positioned in said bus insulator blocks; a plurality of insulator plates, with an insulator plate mounted between adjacent bus insulator blocks and with said insulator plates and pair of block support plates coacting to provide an enclosure for said plurality of bus bars with said bus bars and block support plates disposed parallel to each other; and second connector means mounting each of said block support plates to a cabinet sideplate intermediate said front and rear openings, with said block support plates and insulator plates coacting to provide a barrier defining front and rear portions in said cabinet.

Claim 5

A cabinet as defined in claim 3 in which each of said bus insulator blocks includes first and second sets of openings for bus bars, with said first set displaced laterally from said second set, and in which said block support plates comprise single sheets of metal having identical asymmetrical cross-sectional configurations.

Claim 6

A cabinet as defined in claim 3 in which said closure means includes first and second doors hinged at opposite sideplates with said doors when closed being adjacent one another at a vertical zone intermediate said sideplates; and including a doorstop in said cabinet for pivoting about a vertical axis and having a jamb and spring means urging said doorstop to a stop position with said jamb at said vertical zone closing the space between said doors, said doorstop being movable away from said stop position against the urging of said spring means providing access to the space behind said zone.

Claim 7

A cabinet as defined in claim 5 in which said doorstop is generally U-shaped comprising a vertical jamb with horizontal arms at the upper and lower ends, and including spring plates supporting said door stop at the free ends of said arms.

Claim 8

A cabinet for electrical controls or the like and having a front opening between opposing sideplates, including in combination: first and second doors for said front opening and hinged at opposite sideplates with said doors when closed being adjacent one another at a vertical zone intermediate said sideplates; a doorstop in said cabinet for pivoting about a vertical axis and having a jamb and spring means urging said doorstop to a stop position with said jamb at said vertical zone closing the space between said doors, said doorstop being movable away from said stop position against the urging of said spring means providing access to the space behind said zone; a plurality of bus insulator blocks; a pair of block support plates; first connector means fastening said bus insulator blocks between said block support plates in vertical spaced relation; a plurality of vertically disposed bus bars positioned in said bus insulator blocks; a plurality of insulator plates, with an insulator plate mounted between adjacent bus insulator blocks and with said insulator plates and block support plates coactinG to provide an enclosure for said bus bars; and second connector means mounting each of said block support plates to a cabinet sideplate intermediate said front and rear openings, with said block support plates and insulator plates providing a barrier defining front and rear portions in said cabinet.

Claim 9

A cabinet for electrical controls or the like and having a front opening between opposing sideplates, including in combination: first and second doors for said front opening and hinged at opposite sideplates with said doors when closed being adjacent one another at a vertical zone intermediate said sideplates; a doorstop in said cabinet for pivoting about a vertical axis and having a jamb and spring means urging said doorstop to a stop position with said jamb at said vertical zone closing the space between said doors, said doorstop being movable away from said stop position against the urging of said spring means providing access to the space behind said zone; a plurality of bus insulator blocks; a pair of block support plates; first connector means fastening said bus insulator blocks between said block support plates in vertical spaced relation; a plurality of vertically disposed bus bars positioned in said bus insulator blocks; a plurality of insulator plates, with an insulator plate mounted between adjacent bus insulator blocks and with said insulator plates and block support plates coactinG to provide an enclosure for said bus bars; and second connector means mounting each of said block support plates to a cabinet sideplate intermediate said front and rear openings, with said block support plates and insulator plates providing a barrier defining front and rear portions in said cabinet.

Claim 10

A cabinet as defined in claim 7 in which each of said bus insulator blocks includes first and second sets of openings for bus bars, with said first set displaced laterally from said second set, and in which said block support plates comprise single sheets of metal having identical asymmetrical cross-sectional configurations.

Claim 11

A cabinet for electrical controls or the like, including in combination: opposed sideplates defining a front opening and a rear opening between said sideplates, each of said sideplates comprising a single sheet of metal with an inwardly turned flange at the bottom and at the top thereof; a pair of sill members and a pair of header members, with a sill member and a header member connected between said sideplates at said front opening and with a sill member and a header member connected between said sideplates at said rear opening; closure means carried on said sideplates for closing said front and rear openings; said closure means including first and second doors hinged at opposite sideplates with said doors when closed being adjacent one another at a vertical zone intermediate said sideplates; and a doorstop in said cabinet for pivoting about a vertical axis and having a jamb and spring means urging said doorstop to a stop position with said jamb at said vertical zone closing the space between said doors, said doorstop being movable away from said stop position against the urging of said spring means providing access to the space behind said zone.

Claim 12

A cabinet for electrical controls or the like, including in combination: opposed sideplates defining a front opening and a rear opening between said sideplates, each of said sideplates comprising a single sheet of metal with an inwardly turned flange at the bottom and at the top thereof; a pair of sill members and a pair of header members, with a sill member and a header member connected between said sideplates at said front opening and with a sill member and a header member connected between said sideplates at said rear opening; closure means carried on said sideplates for closing said front and rear openings; said closure means including first and second doors hinged at opposite sideplates with said doors when closed being adjacent one another at a vertical zone intermediate said sideplates; and a doorstop in said cabinet for pivoting about a vertical axis and having a jamb and spring means urging said doorstop to a stop position with said jamb at said vertical zone closing the space between said doors, said doorstop being movable away from said stop position against the urging of said spring means providing access to the space behind said zone.
