12 claims. (01. 241-10) My invention relates to improvements in. panelboards, and more particularly to circuit control elements constructed as sectional units for arrangement in panel formation and for mounting in an enclosing cabinet.
One of the objects of my invention is to provide units, comprising circuit controlling elements, whose relative arrangement and construction of bodv provide space economy .to the end that a greater number of branch circuit controls may be assembled in a given area than heretofore possible.
A further object is to provide panelboard units, comprising circuit controlling elements, of such design as to combine with cabinet parts to form wire gutters or spaces.
A further object is to provide a panel, and cabinet therefor, each having fixed parts which combine to form a wire gutter or space. I
A further object is to provide a panel and a cabinet trim, or front, having related parts, with a mounting, or back, adjustably secured in the cabinet whereby the panel and cabinet trim-may be synchronously adjusted both distantly and an- 2 gularly with respect to the cabinet.
My improvements consist in the novel construction, arrangement and combination of parts as hereinafter fully, clearly and concisely described, definitely pointed out in my claims and illustrated by the accompanying drawings, in
which:--- v I Fig. 1 is a perspective view, partly in section, of a panel board and cabinet, constructed in accordance with my. invention, with certain parts broken away.
Fig. 2 is a fragmental sectional plan view show ing the relating means for the panel and cabinet trim which form the wire gutter and the adJustable mounting for the panel.
Fig. 3 is a section taken on the line indicated 3 -3 of Fig. 2,
Fig. 4 is an enlarged, detail, sectional view showing the adjustable connection between the panel mounting and cabinet.
Fig. 5 is a front elevation of one of the panel Fig. 6 is an elevation, partly in section, of a Panel unit. r
Fig. '7 shows a unit in transverse section as taken on the line 7-! of Fig. 5 and a second unit in end elevation.
Fig. 8 is a front elevation of a panel unit comprising a neutral terminal plate.
Fig. 9 is an elevation, partly in section, of the unit shown in Fig. 8.
Fig. 10 is a transverse section taken on the line indicated 10-40 of Fig. 8..
The structure of the units of the panelboard, of the means for 'adjustably relating the panelboard to the cabinet, and of the means for forming the gutter, may bevaried in form without departure from my invention as hereinafter claimed, the showing of this description and the drawings being merely in illustration of one embodiment of my invention in response to the t5 statutory requirement relating to applications for patent. f
Referring to the drawings, -15 designates the back, 16 the top, 17 the bottom, 18-and 19 the sides of the cabinet, or box, and 20 an inturnedfl flange surrounding the cabinet at the margins of the top, bottom and sides, all oi which, by preference, are formed as a unit of sheet metal. i
The front for the cabinet consists of a trim 21 of open-frame construction and a closure, or door 76 22, hinged in the open frame, and adjustably cured to the cabinet as by clamps 23. v
Carried by the trim, and by preference, flx
thereto, as by welding, is an open frame, comprising a flat 24, welded to the trim next the opening and extending therefrom to forma rabbet 25 for the door to close against, an inwardly and rearwardly inclined return 26 having a rearwardly extended flange, 27, forming parts or a wire gutter.
. .5 Extending forwardly from the back 15 of the cabinet are the stu 28, which, by preference,
arebolts fixedto the ackasbythreadingtherethrough for the 0f the mounting back 29 for the panel. 99 In order to. provide distance adjustment be tween the mounting back and cabinet back I employ spacer nuts 30, on the studs 28, for location between the mounting back and cabinet back, and
to plumb or adjustjhe mounting back vertically 9t relative to the cabinet, in the event the latter may be out of plumb, I provide holes 31 in the mounting back whose diameters are greater than the diameters of the studs whereby the mounting back may be shifted relative to the studs and then .100
secured in properly set position as by the retaining nuts 32. By preference the mounting back consists of spaced metallic strips, each of which is held as by the studs, spacer nuts and retaining nuts recited, and sufliciently rigid to,,105 prevent bending lengthwise. For certaininstallations the metallic strips may be provided with stiflening elements, such as the flanges 33. .At regularly spaced intervals lengthwise of the strips of the mounting back, there are the screw-seats,
34, for the reception of screws, 35, which hold the various units or molded sections of the panelboard in place.
My illustrations have been confined to the construction of the panelboard units, but it is to be understood the wiring may be of the so called, three wire system, in which heretofore, it has been the practice to include in each branch circuit a fuse and a switch in the neutral wire which obviously required space upon the face of the unit.
According to my present invention I provide a special panel section, 36, comprising a plate 3'7, having a plurality of binding posts, or screws 38, for the accumulation of all the neutral sides of all the branch circuits and which plate carries a main terminal 38 for the neutral wire, or side, of the feeder.
By this expedient I may omit the fuse and switch in the neutral side of each branch circuit and -I am enabled thereby to economize in space upon the face of each unit to the end that I may construct a unit with no greater dimensions than usual but with a greater number of branch circuit controls.
In Figs. 5, 6, and 'l I illustrate a unit comprising a body, preferably formed by molding, and formed of insulating material, arranged for the control.
of four branch circuits, in which there are the switch terminals 39, arranged in pairs at each end of the unit, as shown in Figs. 6 and 7, and arranged for connection with busses 40 which latter are for connection with the live mains of the system. In line with each terminal 39 is a terminal 41 leading to a socket 42, for the reception of a plug fuse. Leading from the socket is a bus 43,
having a binding screw 44, and between the ter-- minals 39 and 41 is a switch 45. At each end of each unit is a foot 46 extending below the body proper of the unit whereby all of the live elements of the unit are properly space-insulated from the mounting backs 29.
As shown, the busses 43 and binding screws, 44, are located in notches 4'7 in order to be spaceinsulated from the return, 26, and are thus located outside the wire gutter.
At each end of each unit there is a boss 48 which is notched to receive the margins of the flanges 27 of the return, whereby the return is held properly spaced from the busses 43 and screws 44 and whereby the panel, consisting of a number of the units, is combined with the cabinet front and as a consequence a plumbing of the panel board, as by a shifting of the mounting comprising the strips 29, automatically plumbs the front which comprises the trim 21 and door 22; and by adjustment of the spacer nuts 30 and retaining nuts 32, the mounting back may be moved to bring the bosses to meet the flange 27 of the return regardless of the distance separating the trim and cabinet.
I claim:
1. The combination of a cabinet, a panel and a panel mounting, the mounting comprising a pair of strips between which the panel extends, a supporting stud bolt extending from the back of the cabinet at each end of each strip and means on each stud bolt for supporting the respective ends of the strips and for varying the distance of the strips from the back of the cabinet.
