This invention relates to electric `fuse tofuse pulling and placing tongs. Theprimary object of' this invention is the provision, inv a manner as hereinafter set-v forth, of an improved fuse 'handling tool perfectly insulated against the passage of an electric current from the fuse point to the hand of the person holding the fuse gripper.`

Another object is the provision, inl a manner as hereinafter set forth, of fuse handling tongs of strong and 'durable construction, light in weight,I designed to givev perfect. safety to the user and inexpensiveto manu! facture. y Y Y The invention will Vbe best understood from a consideration of the following detailed de- A scription taken lin connection with the "ac- 2.0 i the invention is not confined to any strict fao companying 'drawing formingV a par-t of this specification, with the understanding that conformity with'the showing of the drawing but maybe changed and modified so long as such changes and. modifications mark no material departure 'from' the salient features. of the'invention' as expressed in the `appended claims. f
