This invention relates to fencing and provides means whereby electrolysis between the metal of the fencing proper and the supports therefor eliminated. c

It is common practice to make fencingof Steel wire and galvanize the same to prevent rust, and to vanized pipe supports. It is diflicult, however, to et an entirely satisfactory galvaniz ing of t e wire fencing, and a much more satisfactory product, both from the standoint of appearance and life, can ,be made om steel wire having a protective coating of copper. Such wire is made by pouring molten copper around a heated steel billet,

l and then by a process of rolling and wire drawing, reducing this bi-metallic billet to wire. From the standpoint of cost, it is still desirable to make the fencesupports of galvanized pipe. It has been found that where copper-protected fencing is mounted on galvanized supports with the fencing in direct Contact with the supports, electrolysis takes place. In the electromotive force series of metals, zinc is 0.770 above hydrogen (zero in the table), whereas copper is 0.336 below hydrogen. Electrolysis therefore takes place very readily, the result being that the zinc is vremoved from the support at points of contact with the fencing, whereupon the supports begin to rust and leave rust streaks on the supporting poles and stringers.

means which is ef- I provide a connecting f fr the e encing om fective for separating t support. Preferably this connecting means 1s in the form of a wire tie having a portion or portions extending -between and separating the fencing from the supports. The tie may be made of any suitable material which will inhibit electrolytic action. For example, I ma use a copper-covered steel wire havingy a eavy lead-tin coating. The value of tin in the electromotive force of metals is 0.192 above h drogen, and-that of lead is 0.148 above hy rogen. The coating 'support this fencing onv galof the fencing and the support in the electromotive force series o f metals.

In the accompanying drawings illustrating the present preferred embodiment of the invention, l

of a tie employed with prises a support made up of (poles 2 and stringers 3 carrying a dlamon mesh wire fencing 4. The pipe and connections forming the fence support are galvanized, as indicated at 5 in Figure 2, while the fencing 4 is made of copper-covered steel wire (see Fig'-r ure 5) having a steel core 6 and a protective coating 7 of copper;

above Stated, electrolysis takes place when fencing-of this character is supported in direct contact with the galvanized poles,l stringers and connections. r`I therefore employ special ties ofthe form shown in Figa ures 3 and 4. Thetieof Fi re 4 comprises a Wire bent to form an eye or loop 8 adapted to receive the fencing, and having portions 9 which extend around i tie is held in place by placing a button 10 over the ends of the extensions 9 and bending the stringers 3. The

' wire in the form of a left-hand ure 6. Each tie comprises clips such as such extensions backwardly, as indicated at 11 in Figure 2. If desired, fthe button 10 may be dispensed lwith and the ties simply twisted around the fencev posts or stringers. 1- The wire or loop 8 is formed by bending s iral.v This isfor the reason that in. diamon mesh fencing of the type shown in Figure 1, the bights 12 which lie closest to the supports extend and to the left, whereas the bights 13, whic lie outwardly of the fencing, extend upwardly and to the right.l It is desirable to attach the ties to the inner bights 12 and where the eye is bent in the form of a left-hand spiral the tie assumes the position shown at A in Figure 1. The tie of Figure 3 ydiffers from that nf' Figure 4 only in that the loop 8a is in the formof a right-handed spiral so that the same assumes a horizontal position, as indicated at B in Figure 1, and is thus properly positioned for attachment to a upwardl v post 2.

in cross section in Figa steel core 14 having a heavy lead-tin coating 15. The button 10 may be similarly coated to protect it from the elements, or may be galvanized. v

It is frequentlynecessary to use a post of H-beam section, and in applying my invention to fences havingsuch posts I employ illustrated in Flgures 8 and 9. The clip of Figure 8 consists of a loop 16 of wire similar to that shown in Figure 6, having arms 174 and 18. These arms lie in the same plane but are spaced a sufficient distance apart to permit of the clip being slipped over the wire of the fencing. vThe arm 17 has a fin er 19 bent to fit around one flange of an H- eam, indicated in dot dash lines at H. The arm 18 has a finger 20 which is bent to the form shown in solid lines in Figure 8 The ties are shown when the clip is supplied to the user, the iinthe case if the loop er being bent around the flange of the H- am post, 4as indicated in dotted lines, to hold the clipv in place. It will benoted that the loo 16 is'elongated. This becomes necessary cause it is desired that the clips be spaced a uniform distance apart, and if the section of the wire fabric does not come v1n the central plane of the postr the elongated loop accommodates it; which were of small size as in Figures 3 and 4. With a circular postthe clip can be turned around the post through a reasonably wide yrange so as to engage thefencing wire. rIhev clip of Figure 9 is similar to that of Figure 8 except that the loop 16a is connected to the arms 17a and 18a through offsets 21. y

By my invention the copper of the fencing is spaced from the zinc of the supports, thus would not be".
