AUXILIARY FUSE-CLIP.

' enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanylng drawings,

which form a part of this specification.

This invention relates to auxiliary fuse clips, and has for its object an improved device for afiording a firmer and more perfect contact between therounded metal ends of the ordinary commercial fuse and the resilient sides or branches of the clip which engage about them, butwhich, after more or less use, tend to become bent out of shape so that a very poor contact-between them, that is, one involving only a small total area of the surface of each is secured. a supplementa piece, not designed to be attached, as by screws, to the insulatingbase or wall panel, but fitting within the regularclip, and'filling all the space between the fuse end and the interior faces of the arms of the clip.

In the drawings:

attachment in place relatively to the ordinary fuse and fuse clips.

' Fig. 2 is an elevational view of the present form of fuse clip.

Fig. 3 is a similar elevation of my auxiliary clip.

Fig. 4 is an elevation showing both clips in place relatively to a fuse.

A represents an insulating plate or base, to which are screwed or otherwise attached a pair of ordinary .fuse clips B which engage about the metal ends of a fuse C.-

lUnder usualconditions, the tendency of each of the resilient-branches or arms of the fuse clips is to become forced farther and farther apart, particularly at their free. or outer ends, so, that the only point of real contact, in the sense of eflicient. electrical service, is along a rather thin line near the base or inner end of each branch, near the point shown by the arrow'srD inFig. 2;"*This results in only a smallpart of the total surface of the metal fuse end, which it is desired that My im rovement takes the form of Figure 1 is a perspective of my improved portions engage.

specification of Letters Patent. Patented Den, 23,1919. Application filed. October 14, 1918. Serial No. 257,985.

the clips shall be in contact with, being thus position the two sideporti-onsE,which begin at the point F to increase in thickness proportionately to the gap that would otherwise appear-between the fuse end and thespection of Figs. 1 and at particularly, that-v the entire surface of the fuse clip arm and of the metal fuse ends C corresponding to the length of the tapered arm portions of the auxiliary clip-are in firm and uniform contact. Thus I secure efficient contact and an even degree thereof throughout the desired extent oneach fuse clip branch.

What ll claim is: u I

1. An auxiliary fuse clip, comprislng a generally U-shaped member adapted to be inserted between the rounded terminals of a fuse and the resilient branches of a clip, the sides of said U-shaped member being tapered as to thickness to substantially fill up the space between the fuse end and the branches of the holding clip.

2. An auxiliary fuse clip having a gentional thickness near their outer ends than their base portions and the central uniting portion of the clip, thereby affording a greater available contact between the ma n clip wherein they are inserted and the ends of a fusefabout which said tapered side 3. An auxiliary unitary Ll-shaped member whose side portions are of tapered thickness from one end to the other, thereby serving as a filler for all of the space between the adjacent sides of an inserted fuse end and the resilient branches of a holding clip.

Intestimony whereof, I sign this specification in the presence of two witnesses.
