Feb. 6, 1923. 1,444,641 A. v. ROWE STEEL FENCE-POST Filed Nov. 25, 1922 "the top ATE."
ALVIN-v. Rowe-or GALESBURG, nlrimors. I
Application filed November 25, 1922. Serial No. 663319.
Toallwhomitmyconcerni Be it known thatI, ALVIN V. Rown, a citizen of the United States, a resident of Galesburg, in the county of Knox and State of Illinois, have invented new and useful Improvements in Steel Fenceposts, of which the following is a specification.
This invention has reference to steel fence posts, preferably made from a structural shape such as a T bar.
Steel fence posts made from T bars are not new. Some are rolled plain and a particular wire attaching means provided, and an anchor plate riveted or-otherwise attached thereto. Others are rolled with various protuberances and a special wire attaching means provided and an anchor plate applied by ,inserting the protuberances through openings in such plate, and the protuberances then riveted down to secure theplate in place. Whatever-the form has taken and in whatever manner the anchor plate has been applied it has been the aim to produce a strong, durable and inexpensive,
post, but for one reason and another these objects have notbeen fully attained. I am, therefore, in the present invention to present a steel fence post, of T design which obviates the objectionable features heretofore encountered, as will be hereinafter more fully pointed out. 4
My invention has for one of its objects to provide the 3108 plate of the T bar with a plurality of spaced studs or protuberances; the studs being of similar design, and each stud being preferably wedge shape, the front face of each stud converging' downwardly from a broad top shoulder to a small squared end. Forming the studs in the shape of wedges on the face plate provides for their easy penetration of-the ground when the-post is driven, and the earth filling in above the broad shoulders at of each stud or wedge tends to seat and lock the studs and render the removal or withdrawal of the post difficult.
The invention has for a further object to provide a new and improved fastening for an anchor plate on the post, without weakening either the post or the plate, in fact materially strengthening both. The anchor plate may be of any approved design, except that it shall have a body portion presenting an extended bearing surface on the face of the post, heated before its application to the post and then given a shrinkage fit to the pst. The contraction of the metal as it cools causing the plate'to' firmly .grip the post and become securely fastened thereon. I preferably provide the anchor plate with an opening through'which a'stud willprotrude, but which does not function as a securing means, except that the wall of'the opening and one end wall of the anchor plate may have an abutting engagement with studs on the post and limitendwise movement, in the event the anchor plate loosens on the post being driven.
That the invention may be more fully understood, reference is had to the accompanying drawings, forming a part of the present'description, illustrating a preferred embodiment of the invention, in which Figure 1 is a front elevation of. my improved steel fence post, partly broken away and with an anchor plate attached thereto, a section of fence ,being shown in dotted lines; a i a Figure 2 is a-perspectrve view of a portion of the post;
Figure 3 1s a detail face View of the post and anchor plate; a
Figure 4'is a rear viewof Figure 3, and
Figure 5 is a'cro ss-section 'in plan as the same would appear if takenon the line 5-5 Figure 3.
Like characters of reference denote corresponding parts throughout the figures;
The post as made from a structural T shape includes the face plate 1 and the rib or web 2.. The face of the plate 1' is rolled or otherwise formed with a plurality of centrally disposed and spaced studs or protuberances 3 preferably Wedge shaped, the wedgesbeing tapered'toward the lower end of the post as shown. In the rolling of the shape and the forming of the studs 3, a rib 4 is formed centrally and'longitudinally' of the post, which aids, as will be shown, in the holding of theanchor plate 5 to the post; The face of each stud 3 converges from a broad top shoulder 6 at its upper end to a small shoulder 7 ,atits lower end. As previously stated the wedge shape of the studs provides for their easy penetration in the ground when the post is driven, and the earth filling in above the broad shoulders at the top of each stud or wedge tends to seat and lock the studs and render the removal or withdrawal of the tain of the studs -will also limit endwise The anchor plate may have any suitable cross-sectional design so long as it has sulficient length and breadth to provide a good bearing surface on the post, and includes preferably-a body portion\8 and wings 9 extending from either side thereof. 'Said plate lies in juxtaposition to the face .plate 1 of the post, conforming to the rib 4 on the front thereof and. gripping its side edges,
and being bent-over the edges of the face plate 1, as at 10, see Figure 5 in the form Theof a tongue and groove connection. plate 5 has an opening 11 therethrough adapted to be passed over a stud 3 on the post; such opening conforming substantially 1 to the shape of the stud, but large enough to allow for playof the plate on the post. The plate 5is of such depth that when it is applied to a post with a stud 3 passing through the openin'gll in the plate, theupper edge of the plate is spaced a little below the lower end of the next and succeeding stud, and the lower'edge of the plate preferably rests on the upper end of the next and succeeding stud. The plate 5 preferably has a shrinkagefiton the post, being first heated and when heated applied to the post,
the body 8 thereof being pressed to con-' form to the rib 4 on the face plate of the post, and the said body also bent over and around the edges of the face plate 1 of the post. As the plate .5 cools it will shrink and as a result becomes firmly fastened on the face plate 1 of the post. If, however,'the anchor plate should become looseon driving the post it can only have endwise movement, and this is limited by the play in.the slot 11 and the upper edge with t e lower shouldered end of thenext and succeeding stud.
In Figure 1, dottedlinesdisclose' a emen of a fence attached to a post. The liiie wires A are attached by some suitable staple -fastener B, and the line wires "as well as the staples are held against "downward move-- ment, should ressure'beapplied to the wires in that directlon, by the broadened shoulders on the upper ends Offliestud's 3; f
