The present invention has :tor its object to produce a simple and novel panel adapted to support numerous fuses or different capacities, the construction being such that the clips for the fuses may be easily removed and replaced and be interchangeable with each other.

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims; but, for a full understanding of my invention and of its objects and advantages, reference may be hard to the following detailed description taken in connection with the accompanying drawings, wherein:

Figure 1 is a top plan view of a fuse panel arranged in accordance with my invention; Fig. 2 is a bottom plan view; Figs. 3 and 4 are sections, on an enlarged scale, taken re snectively on lines 3 3 and 4 4 of Fig. 1; Fig. 5 is a top plan view of one of the unit-s detached from the panel; and Fig. 6 is a sec* tion on line 6 6 of Fig. 5.

Referring to the drawings, 1 and 2 are two longitudinal trame members connected together by aV plurality of broad cross members ot which three, indicated at 3. 4 and 5 are shown. The endmost cross members of the trame are located at some distance inwardly trom the ends of the frame.

The frame is covered with a. slab of insulating material which, in accordance with one feature of my invention, is composed of a large number of sections or pieces of which there are a plurality ot groups ot longitudinal pieces. In the assembled structure illustrated there is a cross piece of insulating material between the central group oit longitudinal pieces and each of the t-wo end groups. and a third cross piece at the outer end ot one of the endmost groups of longitudinal pieces. The cross pieces are secured to the longitudinal Jframe elements, conveniently7 by means of screws 8, and the longitudinal pieces 6 are secured to the cross elements ot' the frame by detachable fastenings, conveniently screws 8. rlhe cross pieces are thinner than the longitudinal pieces so that when a heavy bus bar 9 is laid upon and secured to each cross piece, its top face will be flush with thel top faces of the longitudinal pieces. Each bus bar has a socket 10 extending down from the same through the underlyingpiece of insulation, for the purpose oi" receiving the end of a cable or other heavy conductor. Overlying and secured to each longitudinal piece 6 of insulating material is a pair of clips for receiving and holding a fuse. Fusel clips vary in size and shape according to the capacity of the fuse to be mounted therein. There there are many circuits distributed from a panel there will be a wide variation in the selection ot fuses, according to the use to which the panel is to be put. It is therefore desirable that the fuse clips, regardless of their capacity, be interchangeable with each other so that the panel may be equippedY with any desired selection ot fuses. I therefore so proportion the clips and so Idrill the panel, that the clips for a fuse of any desired capacity may be mounted anywhere on thel panel.

In the arrangement shown, there are clips for four dierent sizes of fuses. One'clip of each pair, indicated at 11, 12, 13 and 14 proliects beyond the corresponding endv of the longitudinal piece of insulating material on which it is mounted, and extends across the adjacent bus bar. Each of the clips, 11 to 14, is fastened to the underlying bus bar by means of a screw 15. Fach clip is also secured to the underlying longitudinal piece of in sulating material 6 by means of apair of screws 16. Each longitueinal piece 6 is also provided with a screw hole 17 into which may be entered another screw 18 in the case of long clips such as the

clips

11 and 12. The second clipV of each pair, namely those indicated at 21. 22, 23 and 24, lies wholly upon he corresponding longitudinal piece of insulating material and is provided with a socket 25 extending` from the same through the insulating material for the purpose of receiving a cable or heavy wire on the rear of the panel. Fach ot the clips 21 to 24 is held in place by means of a 'pair of screws 26. Fach piece 6 is also provided with additional holes 27 to receive vadditional screws 28 in the case of long clips, such as the

clips

21 and 22.'y

' bus bar., as Well as the two screws 8 that hold the corresponding longitudinal piece of insulating material in place, the entire piece or block of insulating materiahwith the overlying, attached pair of clips, 'may be .removedn without disturbing the astenings between the clips and the supporting piece. Therefore,

the user of the panel may be provided with additional blocks or pieces 6 `each Vhaving thereon a pair of clips so that, whenever the capacity lof afuse-is to be changed, an entire section 0I" th'epanel may be removed and re- It will thus be seen that I have provided a simple and novel fuse panel that may be made of any size, by simply using'the proper frame and the proper number of sectionsor pieces of insulating material; one in which clips for different sizes of fuses are .interchangeable; and one from which a pair of clips may readily be removed to make Vroom for another pair. Therefore the panel is not onlyconvenient but it consists of simple elementsY that may be combined Vto produce panels of various sizes. s

While I have illustratedv and described with particularity only a single preferred form of my invention, I do not desire to be limited lto the exact structural details thus illustrated and described; but intend to cover all forms and arrangements which come withinthe definitions of my invention constituting the appended claims. i

claim: i

l. rI he combination with a panel drilled along two parallel rows to receive fastenings forfuse clips, and a plurality of pairs of clips for fuses of different Ysizes kmade in such lengths that the clips of eachpair will be properly spaced to receive the corresponding f fuse when secured-in any pair of holes in said rows. i i l Y s Y 2. In a device ofthe character described, a panel comprisingnumerous pieces of insulating material, asingle cooperating pair offfuse clips on each of said pieces,'an'd means supporting all of said pieces in such a manner that anyof the pieces may be removed independently of the others.

3. In a fdevice of the character described, a frame, a slab of insulating material mounted on the frame and consistingk of numerous individual piecesarranged side by side, means detachably connecting each of said pieces tor the 'frame independently of the other pieces,

and a pair offuse clips mounted on each of said piecesand removable therewith. v

4. .A device of the character described com- 1 prising a frame consisting of longitudinal and cross members,` a slab of insulating material overlying said frame, said slab consistingof groups of longitudinal pieces voverlying and detachably secured to said cross members of the frame and Vinterposed cyross pieces secured at their ends to the side elementsof the frame, bus barsoverlying and secured to said crosspieces, and afpair of fuse clips overlying and securedto each of said longitudinal pieces, one clip of each pair being'detachably secured to one of the bus bars.

In testimonywhereof, I sign this specilication. Y i EDWARD ILANG.
