Y F. J. CZEMBA v FENCE POST Filed May 21, 1934 INVENTOR.

ATTORNEY.

Patented June 30, 1936 UNITED STATES PATENT oFFicE 5 Claims.

This invention relates to anchor posts, and has special reference to one adapted for use as a fence post or the like, the same being provided with novel means for cooperation with a wire fence.

The principal object is to provide a post of this character of as light weight as possible in proportion to its sustaining strength.

Another object is to provide such a post or stake capable of easy construction and in which the reinforcing elements do not detract from the appearance of the post, and which are adapted to perform a double function, operating both as reinforcements to withstand collapsing strain on the post and also as clip cooperating means for attaching the wire to the post.

Another object is to provide such a post having maximum moisture drainage facilities at points of contact between the cooperating portions of the post and wire.

Still other objects and advantages of the invention will appear in the following description thereof.

It is known that the prior art discloses posts of much the same general appearance and which have been widely known as practical and satisfactory posts, for example such as illustrated in my former Patent Number 1,852,910, dated April 5, 1932, on a substantially U-shaped post, but the present invention resides in material improvements upon such a post in the formation of a substantially truncated A-shaped post.

It should also be noted that the present application is a continuation in part of my formerly filed application Serial No. 644,989, filed November 30, 1932.

Referring now to the accompanying drawing, forming part of this application and wherein like reference characters indicate like parts:

Figure 1 is a cross-sectional view on the line l--l, Figure 2, showing the wire holder or keeper in position within the post.

Figure 2 is a section of the line 2-2, of Figure 1.

These posts are formed of rolled metal and require the following characteristics; simplicity of construction; maximum tortional strength commensurate with lightness; adaptability to the supporting of wire fencing; and moisture drainage between the cooperating surfaces of the post, fence wires, and wire attaching means. The matter of general appearance is'also material, though not coverable by a mechanical patent.

In the U-shaped post covered by my former patent, supra, series of notches are formed on opposite edges of the flanges of the post by uniform convolutions longitudinally thereof, these notches obviously being for the purpose of registering with or receiving the longitudinal wires of fencing, which are securely fastened to the postby binding wires, not shown, but common in the art. In this respect the instant invention materially dilTers, in that the opposite edges of the flanges of the post are straight and uniform, while the faces only of the flanges are slightly undulatory, and the notches for the reception of the fencing are provided by a longitudinally disposed scalloped area intermediate the width of the outer face of the flanges and the body portion of the post. These scallops or undulations are formed by spaced indentations longitudinally of the face of the flanges, resulting in a hump on one side and an indentation on the other; it being assumed that the body portion of the post extends forwardly of the flanges.

The body portion of the post is'illustrated at I, the face at 2, and the flanges at 3, while the notches or indentations forming the longitudinal scallops on the back of the flanges are illustrated at 4, resulting in the notches 5 intermediate of the scallops or humps 6 to form line'wire receiving seats.

While I have shown the indentations as being somewhat arcuate in form, it is obvious that they may be either round, square, wedge-shaped, or oblong as desired, and when applied to the post flanges but slightly changes the general shape thereof, and that without any additional stock for formation of the scalloped or notched flanges, which is a material advantage, and also that the protruding or outer edges of the post flanges are uniform and substantially straight. It will be noted that in the rolling process, somewhat distorted conditions of the metal result, so that the apex of each projection or hump is less in thickness than the normal thickness of the flange, but which, of course, may be varied by changing the form of the rolls.

Now as a combined reinforcing and wire attaching clip mounting means for the post, ma terially increasing its resistance against tortional stress, two parallel ribs 1 are formed extending inwardly from the body portion and approximately midway the opposite extremities of the upper face thereof ;to provide adequate drain'-' age of moisture in theevent of its becoming wet, I

as this feature'of drainage is one of material.

. post. The inner walls of these ribs are inclined U as at 8 for convenience in the rolling process and to form supports for the wire attaching clips hereinafter described, as the post bar is gradually contracted during'its formation from a substantially flat bar to the ultimate truncated A shape desired. r r

r The clip, insertablewithin the post at, any

point from the back thereof, is illustrated at 9,

and is provided with a body portion I0 of an outlinelsimilar in shape to the interior of the post, it being formed with inclined shoulders for abutting engagement with the similarly shaped inner walls of the ribs 1, as shown at. 8 in Figure l of the drawing. This clip is novel in that it is provided with a comparatively large central hole ll through the body portion I0, I

which hole is concaved or countersunk from the importance in the instant invention. .To'further such drainage the finger like extension of the clip, substantially midwayits ends, is-made.

concavo-convex, and the convex surface thereof is opposite to that of the countersunk hole in the-body portion. This shape of the finger is about same; that is, a joint that would tend to distinctly shown inFigure 5 of the drawing, and, asis obvious, is to-prevent forming a closed, joint between the finger and the wire when it is bent hold moisture by capillary attraction, as, when a finger, thus shaped, is bent about the wire, only the central portion thereof engages-the latter, the edges being, spaced slightly therefrom as clearly shown. 7

Still another feature of novelty in connection" withthis combination of wire and post is that the indentations 4, whichform the scallops .6,

' are more or lesscontinuous intermediate of said scallops, as clearly shown in Figures 1, 2 and 4 of this application, as well asin Figures 1, i and5 of application, Serial 644,989, of b which this is a continuation in part;

The .continuation of the depression or notch forms somewhat of a rib intermediate of the scallops 6 on the back-side of the post, and which rib functions to keep the wire away from the :flat face of theflanges 3 as clearly illustrated in Figures 1, 2 and 4 of the drawing, thus providing water drainage under the wire. r

I am aware that somewhat similarly shaped clips; have been made to hold a wire against the back of a post, but this, I believe, has only been 'them useless after but short service.

, Furthermore it will be apparent that an A used in conjunctionwith a wedging member for retaining the clips in position, Such an assembly is obviously inadequate and does not provide for theexpansionand contraction ofthe post during changes in temperature, which would render shaped post of the specific structure shown,

7, shaving inwardly opposed ribs for both adding strength to the post and for holding, means for,

-cated .A shaped in cross section having longithe clips, in conjunction with laterally extend-s ing flanges having means integrally formed therewith for holding wire fencing in spaced, relation therefrom, provides a most ideal fence post. a T f It might also be herestated that exhaustive tests have shown. conclusively that posts constructed in accordance with-applicants 'disclosure herein, having an efiective'area of section of .42 sq. in. and weighingper foot 1.4112 pounds, have a fargreater polar moment of inertia or polar sectionmodulus than any other competing.
