Abstract

116,894. Athimon, F. June 19, 1917, [Convention date]. Pliers for forming loops or eyes in the stav wires of aeroplanes comprise a pair of pivotally connected crossed handles, the upper ends of which are provided respectively with a pair of pivoted forming-cams and with a co-acting forming- mandrel. The cams f, f<1> are pivoted in recesses in the handle member b<1> and a covering member d and are so shaped as to form a frustoconical cavity between their opposed faces, being formed with nose parts f', heel parts f<3>, and also with a series of annular grooves f<2> of different sizes to receive wires of different diameters. The cams are normally held with their nose parts f<4> in contact by a spring g. The mandrel h, carried by the handle member a<1>, is formed with a frustoconical part h<1> having grooves h<2> corresponding to the grooves f<2> and a part h' with concave sides. In use, the stay wire i is inserted between the heel parts f<3> of the cams and the part h<1> of the mandrel within the grooves f<2>, h<2> corresponding to the size of the wire, and the jaws are closed. The cams turn against the action of the spring g and the wire is bent closely about the mandrel h.
