WIRE-NETTING.

SPECIFICATION forming part of Letters Patent No. 259,989, dated June 20, 1882.

A pplicuiiun tiled April El, 18.42.

(Minh-l vl To all whom 'it 'may concern Be it known that I, GUSTAV Prominente, of Hagen, in the Empire of Germany, have invented a. new and useful Improvement in \-Vire-Netting,ot' which the tollowingis a speci- Iication.

The object ot' my invention is to provide a new and improved wire-nettin g, which is stron g and durable and of simple construction, and in which the edges are iinished and made strong and in such a manner that they cannot r catch on objects.

Theinvention consists in wire-nettin g formed of a series of united link-sections each formed of oneror more spirals screwed into each other, the spirals of one link-section bein g screwed into the spirals of the next sections and wires being passed through the loops formed by the overlapping parts of the spirals.

The invention further consists in bending the ends of the spiral wires and the connecting-wires over on the ends ot' the sections for the purpose of finishing the edges ot' the nettina- Theinvention also consists in spira-ls screwed into the adjoining edges ot' two link-sections, made of spirals, for the purpose ot' uniting these two edges.

Reference is to be had tothe accompanying drawings, forming part ot' this specification, in which similar letters of reference indicate corresponding parts in all the figures.

li'igure l. is n. I'ront elevation olf :L piece ci' myilnproved netting. Fig. L isa longitudinal sectional elevation ot' the same. big. :3 is a longitudinal elevation ot' one of the. spirals.

The netting is formed oi' a series ot' longitudinal link-sections, A, formed ot' oneor more circular or ilat spirals, nmdeot' wi re and screwed into each other.` 'lhe spirals ofthe several link-sections are screwed into each otherwthat is to say, the upper ends of the spirals of one section pass through the lower ends otl the spiralsV ot' the next higher link-section, and wires B are passed through the spirals longitudinally in such a manner that these wires alternately pass through the upper end i' a spiral or spirals ol' one link-section and then through the lower end ol' the spiral or spirals of the next link-section, whereby the spirals will be more Iirnily united. As is shown in Fig. 2, the spirals pass through each other and the wires l pass through the elves formed by the overlapping parts of the spirals. The endsof the spirals() are bent over against the ondsof the sections, and the ends ot the coupling-wires B are also bentoveron the endsol'the be iinished and will have no projecting parts on which objects might catch. ln thc specimen represented cach link-section is l'ormed ot three spirals screwed into each other. lnstead of three, any number ot' spirals may be provided in each link-section, and the pitch ot' the spirals can be varied according to the deA sired tineness or coarseness ot' the netting.

it' desired, two wires, B, may be used at each `joint, which construction is of special advantage it very strong netting is t0 be made. ll' ends ot' such netting or several pieces ot netting are to be united, one or more circular spirais, l), are screwedinto the two longitudimil edges of the -linli sections A that are to be united, as shown in Fig. 1. All the spirals may be made circular, but this makes the netting very thick and cumbersome, and for that reason I prefer to use flattened spirals, as shown. lhe cross-section ot' the wires may be circular, square, oblong, polygonal, and in fact may have any desired cross-section without altering or nilecting the construction ot' the netting. The width and length ot' the link-sections may lic varied ns circnmslnm-cs may require.

lhe hercin-described wircnetting is to be. used for making elevator-belts, driving-belts, metal cloths, do., for making safes and chests, shot-proof l'abrie l'or military use, armor, rolling shutters, tire-prooitheater-em'tnins, which may be provided with :t covering on one or both sides.

This netting can also be used as an armor for vessels, or as a torpedo-protector.

Having thus fully described my invention, I claim as new, and desire to secure by Letters Patentl. Wire-netting made, substantiallyas herein shown and described, ot' a series oi' spirals screwed into each other and having connecting-wires passed through the loops formed by the overlapping parts 0l' the spirals, as set l'orth.
