Electric fittings.-In a machine for making- grids for electric discharge devices by coiling grid wire on one or a pair of support wires, which are at the same time notched to receive the turns of the grid wire and the edges of the notches closed to secure them therein, the support wire is notched by compressing it in a direction substantially transverse to its axis so as to avoid twisting or bowing of the finished grid. The support wires 15, 16 are mounted on spools on a head 12 which is rotated by gearing 17, 18 from the main shaft 19. The wires are led along grooves 23, 24 in a sleeve 22 secured to the head and over grooves in a flat mandrel 31, which is secured by a screw 33 to a cutter head 26 screwed to the end of the sleeve. The ends of the support wires are secured to a clamp 36, which is carried bv a slotted sleeve 75 traversable by a split nut 76 on a screw 77, and rotated by a keyed gear 79 engaging a gear 82 on the main shaft. The cutter head carries a pair of radially movable cutters 27, 28 normally pressed outwards by springs 43 but pushed forwards to notch the wires by a fixed member which engages the ends 44 of rods 41 during rotation of the head. The grid wire 37 is led to the support wires from a spool 38. The edges 51, 52, Fig. 6, of the notches are closed round the grid wire by hammers 47, 48, normally pressed radially outwards by springs 58, 59 in a head 53 rotated by gearing 55, 56 from the main shaft. The hammers are pushed forwards by contact with a cam 61 on a slide 64. In order that the grid strip may be left at intervals with unsecured wire for the purpose of providing projecting unwound legs when the strip is subsequently cut into lengths of desired size, the slide 64 is pivoted to a lever 66 pressed by a spring 70 into contact with a cam 68<1> rotated by ratchet gear from the main shaft. The cam 61 may thus be moved at intervals out of range of the hammers. When the sleeve 75 has reached the end of its traverse, the completed section is cut off by treadle-operated shears 83, 84.
