W IRE FENCE.

Specification of Letters Patent.

. Patented. April 6, 1909.

' Application filed August 20, 1988; Serial No. 449,397.

T 0 all whom it may concern: Be it known that l, LAURENCE S. Lann- MAN, a citizen of the United States, and

wherein the longitudinal line-wires or strand wires are united at intervals to transverse 1 wires forming stays, by means of pieces of metal which are electrically welded to thewires about their intersection.

vide a fence having greater strength and durabilitythan the ordinary wire fence, the wires of which are welded at their intersection'. r

The objects of the invention arealso to provide a form of construction which permits of the fence being made in a great variety of shapes both for ornamentation and strength at a very low cost.

Referring to the drawings: Figurel' is a rear elevation of a portion of a fence con- Y Fig.2,

structed according to my invention. is a plan view of one of the weld pieces. Fig. '3 is a cross section of Fig. 2. Fig. 4 is a plan View of any alternate form of weld piece. Fig. 5 is a cross section of Fig. i. 6 is a plan iew of an alternate form of weld piece. Fig. 7 is a cross section of Fig. 6. Fig. 8 is an end View partly. in cross section and with parts broken away of Fig. 1'; Fig. 9 is a detail perspective, view showing the intersection of the wires Fig. 10 is a detail of an alternate construction.

In the drawings, A designates the strand wires of the fence and B designates the stay wires which are arranged to cross the strand wires at any desired angle, the wires being securely held together at their intersections by means of buttons or small pieces of sheet metal C, -which in the present instance are provided with at least one ridge D'which projects' above the surface of the adjacent metal of the button and corresponds approximately in cross-sectional area to that of the wires, so that when an electric welding current is passed through the ridge D and the wires A and B and the same are forced together, in any desired manner, the metal at the points of contact both on the wires and the ridge D will be heated to-the welding temperature after which the same are forced together until the metal ofthe-button C and the portion of the wires adjacent to the points of welded union meet and contact so as to short-circuit the welding current by affording a larger )ath for its assage, the metal of the wires eing welde to ridge D at-eachintersection i of the wires as shown in vFi 8. The buttons C are usuaFly constructed of sheet metal suitably ressed to form the ridge D although the ri ge D may be madein any other desiredy namier, it being immaterial whether the ridge D is forced up out of x the metal as' shown in Figs; 5 and 7 or whether The objects of the invention are to pro-j the same is simply pressed as shown in Figs. 2, 3,4 and 5. l

If desired the buttons may be provided with a plurality of concentric ridges, pro vided the buttons are made large enough to space the different ridges far enough apart so as to facilitate the welding current being short circuited when the button is pressed in contact with the wirefij-and also to facilitate the ridges being brought to the proper welding temperature. V

it is obvious that the buttons may be made any desired shape so as to harmonize with the general design ofthe fence and it is also obvious that theridges are not necessarily made continuous and can ust as well be pro .vided only where the wires are to be=welded thereto, the remaining portions of the ridges being of no advantage in welding the parts together but of considerable advantage as the same is easier to put in place and manufacture.

The buttons 0. also'permit' wiresE beingwelded to the same, so as to in-' crease the strength of the fence and change the design in a great variety of ways such as that shown in Fig. 10.

-As shown in Fig; 1 the cross stay wires E are made in short lengths but the same may cheaper. to

be made in one piece so as to reach from the top strand to the bottoinstrand wire-of the fence. 4

When the wires are made to cross each other such as the wires A and B, the same are preferably bent or kinked at their intersection as shown in Fig. 8 so as to give a more finished appearance to the fence and lambtate the ridge D connng in contact with the wires where it crosses them.

The button C as before described, permits of the wires A and B being welded at of the crossfour different laces at each intersection thereby obvietingell chances of the wires ever coining-apart. The button also has the additional advantage of permitting cross wires'to be welded to the same so as "to in- 'ereasethe strength utility and beauty of the made and still fall within the scope of the appended claims.

What I claim 1s: v 1, A ire fence comprising a series of strand wiies and a series of stay Wires, nude ridged butt0n, said strand and stay Wires being weld-united to the. ridges of said button.

2. A Wire .fence comprising a series of strand wires and 11 series of sta, wires, 2. ridged button, the ridges of said utton being approximately of the same cross-sectional area as the strend'a-nd stay Wires tofwhich the ridges of said button are Weld-united at the intersection of said strand and stay wires.

In testimony whereof I have signed this.
