METALLIC FENCEPOST.

Application lfiled January 18, 1922. Serial No. 530,038.

To all whom t may eoncem: Be it known that I, CRAWFORD B. .MUR-

' TON, a citizen of the United States, residing lic Fenceposts, of which the following is a' specification.

My invention relates to fence posts, more particularly those constructed of metal, and

the object of the invention is to provide a post to which the ground anchor may be secured without puncturing the post and by elements integral with the post itself. My purpose is to provide a construction which avoids the need of a clip and extra perforations, and makes it possible for the elements on the postvto hold, unaided, the ground anchor in position. Another object is to provide, in a post of this type, a construction such that the manufacturer may have a choice as to .the position of the ground anchor, lengthwise ofthe post.

I accomplish my objects by the construction illustrated in the accompanying drawings in Which- Figure l is a general assembly view in perspective showing the post inserted in the ground, Vrand thev ground anchor and fence wires in position.

Figure 2 is a detail drawn on an increased scale showing a ground anchor secured to the post. The view shows the ends of the lufrs riveted over onto the ground anchor.

igure 3 is a vertical section on the line 3 3, Figure 2. Y Figure 4 is a plan section on the line F iofure 2.

Figure 5 is a plan section on the line 5:5, Figure l, and

Figure 6 is a pers ective of the preferred form of ground anc or.

Like numerals denote like parts throughout the several views.

According to the design illustrated the post is a metallic T bar havingia front or head 1 and-a web or stem 2 extending rearward. A low rib 4' extends longitudinally along the frontof the bar and at intervals there are lugs 3 adapted to penetrate the slots 6 in the ground anchor 7. By preference the sides of the lugs are parallel with the length of the bar and the sides of the slots are arallel and fit fairly closely to the sides of t e lugs so as to prevent undue lating bars and angles it is practically .impos- .eral movement of the anchor. Whilethe form of the anchor ma be varied, it is here illustrated in the ferm of a regular trapezium, the shortest side whereof is arranged at the bottom.

In general, the parts above mentioned are the same as in the aforesaid Jones application, but according to my invention the lugs project farther from the surface of the bar, thus affording suiiicient metal vfor the pro'- jecting vends to be riveted over onto the front of the anchor for holding it in place. In other words, whereas in the form shown in the Jones invention the anchor has two sets ofl perforations, one set for the lugs'and the other set forthe fasteningclips, I omit the second set and the clipsand increase the height of the lugs and supply enough metal fin them to form a head or rivet for holdin the anchor in place. There are several a vantages in this. In the first place, only a single set of perforations in the anchor yis reorany o the other advantages obtained by the Jones post. While it is not essential that 8 the anchor be fastened at the mill or place of manufacture, this is nevertheless, desirable, as machines are usually available there for the purpose. As pointed out in the vJ ones application, the advantage in forming the sides of the lugs parallel to the length of the bar and elongating the slots 6 and the anchor, is to enable the anchor to accommodate itself to variations in Aspacing of thelug. In rollsible to form lugs on accurate spacing, as the spacing will vary somewhat in accordance with the temperature of the bar at the time it is rolled'. By elongating the slots as described, the anchor will vaccommodate 100 present case I have illustrated means similar 1'05 to the one shown in the said Jones application. The fence wires 10 are held inlplace by clips 12 formed preferably of round rods bent in such manner as to pass over the front of the wires and engage 'the marginal 11o I without ,sacrificing anything in the way of security fianges of the bar. Usually one end, as la,

is sent from the factory, ready bent, while the other end l5 is left bent at right angles to the body of the bar, as shown in dotted lines in Figure 5. After the parts have been adjusted this end l5 can be set to final position by a hammer or other tool.

lt is desirable to alternate the slant of the clips, as this seenisto be a more effective manner of preventing any vertical displacement of the fencing. lt is also desirable, although not'necessarj' to cup the tops of the lugs, as best illustrated in Figure l. rl`his causes the metal of the lugs to flow more freely over onto the top of the anchor, and prevents the metal from spreading at a point between the inner surface of the anchor and the adjacent surface of the post. v

My post also has an advantage from the ma'nufacturers standpoint in common with the Jones type of post in that the bars may be produced invcontinuous lengths and then cut off to form stock or special sizes. rl'his results from the fact that the lugs extend at intervals along the entire post. Of course all of them will not be'used in practice, and theoretically, certain of the lugs may be omitted, but itv is advantageous, at least from the manufacturers standpoint, to prospacing the Wires, and a ground anchor in the form of a platel having apertures for re ceiving said lugs. said lugs projecting sufficiently to penetrate the plate and leave suicient metal to be riveted over on to the outer naaaaae surface of the plate, said lugs thereby performing the additional functions of holding the ground anchor in proper location on the post and fastened to it.

2. A metallic fence post having a longitudinal row of lugs projecting from onesurface and a ground anchor adjacent to said surface, the lugs having iat sides parallel to the sides of the post and the anchor having slots adapted to fit the lugs approximately at the sides, the slots being elongatedfor accommodating variations in the spacing of the lugs, and the lugs being appreciably higherthan thc thickness of the anchor, and the metal of the lugs being expanded over onto the outer surface of the lug for holding it in place.

v3. A rolled metallic fence post in the form of a T bar having a row of integral lugs on its front and a ground anchor having slots for accommodating them, said lugs being of greater height than the thickness of the anchor end to facilitate riveting of the metal and a flowing of it onto the front of the anchor, saidrow of lugs extending approximately from end to end of the postwhereby the ground anchor may be variously positioned and the upper lugsmay serve to limit the vertical movement of the fence Wires.

4. A rolled metallic fence post having a chiefly flat front surface having a low rib running lengthwise of it with lugs projecting forward from the rib and therefore being in alinement With each other, and a.

ground anchor having a plurality of apertures one above the other and adapted to accommodate the lugs, said 'lugs projecting forward further than the thickness of the ground anchor to thus afford sufficient metal to be riveted over against the front of the ground anchor to retain it.

In Witness whereof, I have hereunto subscribed my name.
