WIRE STRUCTURE No. -9 l2,481.

- T 0. all whom it may concern:

Be-it l nown that l, THOMAS {-r. lVlnLisn, a citizen of; the United States of America, and aresident of 'incinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in 1 1 1 P I. Wire Structures, of whicn the renewing 1s a specification.

illgis invention relates to wire sti'uctures and nilire gspgciailrtothose used in the couitructioyl and manufacture of rat-traps, grading screens for sand and the like, and its object is to providesstrong. and durable rib or tie-bar that is adapted to be interlocked with and engaged by mesh-wires in silently and effective manner, a series of such ribs or tie-bars being used in parallel array along the wire-mesh, transverse to the latter and holding them a suitable distance apart free from any possiblelateral play or disengagementattheseveralintersections.

'ihe invention consists in certain novel features of the construction, combination and arrangement of the several parts of the improved Wire-structure, whereby certain important advantages are att ained and the de vice is made simpler, cheaper and otherwise better adapted and more convenient for ap .plication and use in rat-t-rap, sand-screen and similar structures, all as will be hereinafter fully set forth.

The novel features of the inventionwill be carefully defined in the claim.

In the accompanying sheet of drawings illustrating my invention, i igure 1 is a fragmentary plan view ofa wire-structure embodying my invention, showing such inven tion in a number of correlative forms; Iig.

transverse section of the rib or tie-bar shown both in Pig. 5 and at the extreme right in Fi 1, but with the two parts of the said rib shown apart and in position ready to be closed over a mesh-wire, the latter not being shown in this view; and big. 8, a fragmentary longitudinal central section of the rib or tie-bar seen in Fig. 7.

In these vievrs, 1 represents the ordinary mesh-sires, v: hich are arranged parallel to. each other andare preferably plain or unbent ones, but they are adapted to be bent at the desired points in rat-trap or similar structures and not necessarily bent at the intersections of the cross-ribs or tie-bars such as I use in my structure and which I v. ill now describe. Transverse ribs forming tie or bindingbars are provided, to suitably space and firmly hold the mesh-wires in suitable parallel positio'n, duly'separated as customary in rat-trap and grading-screen structure's. These ribs or tie-bars are of peculiar construction and form the essential feature of my invention herein. They are each com-- posed of a pair of bars or dates formed of narrow strips of sheet-meta the mesh-wires being held between each air of saidstripsL For convenience, I wifldesignate 2 as the lower or base-plate and 3 as the upp er or clamping-plate of each. air of plates or strips forming the several ri s or tie-bars of my structure. These numerals, -2 and 3, are employed in connection with each of the plates or strips forming the ribs seen in Fig. 1 and 90 the following four views. A series of crimps 4 s made In the several plates 2 and 3, of F1 '2, such crinips being disposed outwardly and or prongs made in the lower or base-plate 2,

alternating "with the transverse crimps 4, and 6 Indicates eachone of a series of transverse slots provided in the upper plate or strip 3,

alternating with the crimps 4.in that strip, all as best seen in Fig. 6.' When the two plates 2 and 3 are brought together for closing over a series of transversely-disposed with the outer ends of said pro clenched or bent down on the out.er .'nee-et--11o mesh-wires 1, the crimps 4 coincide or registhe strip 3 so as to firmly unite the two strips 2 and 3 together over the series of mesh- .wires.

. Each of the first five views of the sheet of drawings shows the manner inwhich the tongues or prongs 5 are clenched and the two parts of each of the ribs or tie-bars secured together with-the mesh-w ires held between each pair of strips.

I-prefer the construction seen to the exf treme left in Fig. 1 and, also, shown in Fig.' 2

' bearing wires in the crimp-receptacles of Fig. 2 is obviated and especially when the strips of sheet-metal are wide ones whereby a longer is provided for the mesh-' hes in the I tie-bars.

- in the fastening v In Fig. 3 I have shown crin1ps4 in the upper plate 3 only, the lower plate 2 having no crim s therein, thus providing a receptacle for t eseveral mesh-w ires in said upper plate or strip only; 'The crimps in this form must necessarily be deeper than those in each plate of the form seen in Fig. 2, so that the lower structure comprising suitably spaced meshplate or strip 2 can be clamped contiguous to the upper plate and to the mesh-wires 1 of the two plates or strips 2 and 3 over the said mesh-w ires.

In Fig. 4 I have shown the same deep crimps seen in Fig. 3, but these crimps are made in the lower plate 2 instead of in the upper one, and the effect is practically the same as in the form seen in said Fig. 3.

I In. Fig. 5 I have shown a rib or tie-bar stru'cturefthat is extremely stiff and strong as a result of makmg the lower plate or strip 2 a channeled one, with upturned side edges or flanges 7, 7, such flanges being provided with vertical notches 8, the latter as best seen in Fig. 8. 'lhe notches 8 form reoeptacles for the mesh-wires and take the place of the crimps 4 seen in 4. 'lhe upper strip 3 is a plane'one in this form, the same asgthat seen in Fig. 4 and the strips '2' and 3 have the prong and slot formations, 5 and 6, I respectively, the same as in the previous views of the drawing, and said rongs are clenched 111 a like manner. In ig. 8, however, I have shown that it is not necessary ribs or tie-bars if desired, especially if a very strong and rigid wire-structure 1s not required. 'I he upper plate3 in the form seen in Fig. 3 is of the same width as the space between the flanges 7, 7 of the lower strip 2, so

that said upper plate can be brought withinthesaid flanges 7, 7 and clamped firmly in said Fig. 5.

It is obvious that instead of making elongated openings or slots in the top plate or stri 3 and the broadtongues or project-ions in t e bottom strip 2 of each rib or tie-bar, small circular openings could be made in said upper strip 3' and narrow pins or tongues to corres 0nd tosuch small openings could be made in the lower strip 2 and a like looking result be effected, except that it would not be quite so stron I I claim As a new article of manufacture, a wire wires and a series of intersecting double strips of sheet-metal, such mesh-wires being helcl at suitable intervals apart between said double strips, one of the strips having a series of suitably spaced transverse slots and the other strip having a series of correspondingly spaced integral tongues adapted to register wlt-h and engage said slots and clenched on the outer face'of the strip containing the slots for uniting the strips and clamping them firmly over and in suitable engagement with the mesh-wires, and a series of transverse seats or depressions made in one or both of sa1d double-strip members and ntervemng the respective slots and tongues thereof.
