3 Claims. (CI. 81-51) This invention relates to hand tools and has securely grasping the terminal during the wire particular reference to a special tool for entering inserting operation. the ends of a stranded wire into an aperture. It Referring now more particularly to the drawis particularly designed for entering stranded ings, it will be understood that in the embodiment wire into the hole of a stake-on lug or terminal. herein disclosed, my improved device consists of In utilizing certain types of lugs or wire tera pair of jaws l0 and II, having complementary minals it is very difficult to insert the stranded handles 12 and I3, which are pivoted at M, to wire in the aperture of the lug, preparatory to the function in the manner of a pair of pliers. The staking operation, particularly is such insertion device is provided on one side (Figs. 1 and 3) with difiicult where the aperture is not exactly round a circular bore having inclined side walls IE. or where there is some interior obstruction in the The device is provided on the opposite side (Figs. hole, as is the case when a lug is used as shown 2 and 3) with a circular bore l1, having substanin the drawings. tially straight walls I8. The bores l5 and H In certain applications the lugs "or terminals are communicate with one another, but the bore I1 is secured to the fixtures before the latter are wired, 15 larger than the reduced end l9 of the bore l5,
