Abstract: 27,501. Boult, A. J., [Lamb, C. M.]. Dec. 16. Fencing.-Relates to machines for making wire fences, and comprises means for curling the strands, cutting the stays from a spool of wire, and feeding them across, and wrapping them around the strands. Fig. 1 shows a plan of the machine, and Figs. 2 and 3 side elevations of parts thereof. The strands pass over a measuring feed-drum B to a curling and crimping device C; the stay-wire is fed by mechanism J<1> from a spool J<2> to knives J, the severed stays passing to rotary wrappers G<1> ... G<10> reciprocated longitudinally by cams on a slide F and operating successively on each stay. The fence is stretched and straightened in its passage by hooks on endless chains K, and is wound on a collapsable drum M. The main shaft E drives the drum B by a chain a, the slide F by bevel-gearing a<1>, and the drum M by a belt a<4>. The curling and crimping mechanism comprises hollow shafts c<2>, Fig. 26, through which the strands pass and over rollers c<15> on the shafts ; the latter are driven by an endless chain from bevel gearing c<14>, Fig. 1. The slide F, Fig. 7, is fitted with upper and lower racks f<24>, f<25> and adjustable camsp, f oppositely arranged ; rollers f engage the upper cams, and are mounted on bars f<9> moving in guides f<10> and connected at the front to bearings for the wrapper shafts G, G<3>, G<5>, G<7>, G<9>; the lower cams receive rollers f<13> pivoted to bars f<15> sliding in guides f<16> and carrying bearings for the wrapper shafts G<2>, G<4>, G<6>, G<8>, G<10>. The slide F is guided by cross-members A<4>, Fig. 1. The stay-wrappers with the wrapper G<1> gear alternately with the racks f<25>, f<24>, while the end wrappers G, G<10> are geared to rotate faster than, and oppositely to, the wrappers G<1>, G<9> to produce the end-bends. The wrappers have hooks, shown in Figs. 15 and 29, which successively wind each stay around the strands ; the strands are inserted through the side of removable slotted plugs g<13> in the wrapper heads, and are tightened by tension rings h<12>. The stays are carried across the strands by notched discs g<22> and blocks h<8>, Fig. 14, operated by rods h, h<2>, &c. from a rocking shaft I. The stay-wire is fed intermittently from the spool by feed-wheels j<27>, Fig. 4, and j<28>,j<31>, Fig. 23, driven by gearing j<15>, Figs. 3<a> and 4. The wire passes by a tube j<11>, Fig. 20, to a cutter head j<7>, shown also in Fig. 22, mounted on a shaft j slotted longitudinally and rotated intermittently by a disc j<5>, Fig. 10, and pawl j<6> on the slide F. The wire enters one of the slots in the shaft j, is severed, and is transferred by the first set of blocks h<8>, Fig. 22<a>, and projections j<13> to the first strand, the ends of the stays being bent by fixed members H<6>, Fig. 1. The take-up drum M, mounted on a universal joint, consists of four collapsable sections m<4>, Figs. 7<a> and 7<b>, operated by handles m9, m<14> to release the fence, and provided with sheathable hooks. The stays may be of unequal length, and one or more top wires or strands may be applied in a similar manner to the fence, and have slip connections with the main stays or strands.
