METAL FENGEPOST.

Specification of Letters Patent.

Patented Nov. 2, 1920.

Application filed. May 13, 1922. Serial No. 380,985.

To all w ham it may concern Be it known that I, EDGARE SPENCER LACHMANN, a citizen of the United States, residing in the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Metal Fenceposts, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to pro vide an improved metal fence post, adapted to be self-anchoring in the ground, and to be more easily driven, and to be held more securely by its anchoring than like posts heretofore in use. It consists in the elements and features of construction shown and described, as indicated in the claims.

In the drawings:

Figure 1 is a perspective view of the fence post having an anchoring base embodying this invention.

Fig. 2 is a direct or forward side elevation of the lower portion of the post comprising the anchoring element.

Fig. 3 is a section at the line, 3-i3, on Fig. 2.

Fig. 4: is a view similar to Fig. 1 showing a modification.

Fig. 5 is a view similar to Fig. 3, showing the same modification.

Fig. 6 is a view similar to Fig. 5, showing a right angle bar post member instead of a T bar, as in the other figures.

The post proper consists of the metal bar, 1, of angular cross-section, the particular roll section herein shown being that of T section having the lower end of the web and flange thereof clipped at an angle to conform to that of certain anchoring bars or straps attached thereat.

The anchor device is composed of flat bars of suitable size secured to the post as by spot welding or riveting as shown. The

two bars, 2, 2', are secured to the cross flange A bar, 4-, is secured to the stem flange of the post at the lower end thereof at 4- in the same manner and at the same or similar angle as the bars, 2, and is likewise connected to the post at its upper end by a bar, 5, which is secured to said upper end at 5*, and to the stem flange of the T post at 5.

It will be observed that the anchor members are all laid fiatwise against the flanges to which they are respectively secured, and that the members which are connected together are also joined with regard to having their wider surfaces in contact thus affording means of sec1n7ement without bending any of the members to obtain minimum thickness for penetration of the securing devices.

Another advantage to be derived from the present construction is that when the post is driven into the ground the anchor members are presented edgewise, thus affording com paratively light resistance because very little earth is displaced, and this small quantity may be readily replaced by tamping so as to occupy the triangles circumscribed by the anchor members.

The purpose and operation in practice of this construction is that when the post is driven into the ground with the bars, 2 and 3, in a plane parallel to the direction of the length of the fence, the breadth or fiat side of the bars is positioned to strongly resist deflection of the post laterally with respect to the fence; while the members, i and 5, operate to offer resistance transversely thereto which is considerably less in the direction of the length of the fence. The anchor members being made of comparatively short pieces and needing no shaping, bending or other forming other than clipping or cutting to approximate size or length, makes it possible to utilize otherwise waste or scrap material, it will be seen that the present invention contemplates an economical, eflicient and durable fence post construction.

For convenience and economy in shipping, it is desirable to omit the anchoring parts at one side of the post, leaving them extending only so as to occupy vertical planes making a right angle, instead of a cross or two right angles. In this form, shown in Figs. 4:, 5 be nested compactly for shipment, as is not the case in respect to the T-form devices shown in Figs. 1, 2 and 3.

Also, it is somewhat preferable in the and 6, the devices can in the other forms, and the bars, I} and 5, to the inner'faces of the angle of the post memher from which they respectively extend, so-

that if, for example, the post is a right angle iron bar, as in Fig. 6, instead of'a V T bar, as in the other figures, the outer side of the angle may present plane surfaces without projections.

I claim 1. An anchored metal fence post of which the main post member consists of a bar hav ing a plurality of longitudinally extending flanges angularly disposed with respect to each other, said flanges being tapered to a common point at one end ofthe post, and an anchoring element comprising a flat bar secured flat-wise to one of the post flanges, extending divergently upward from the pointed end of the post and a flat tie-bar connecting the'upper end of said divergent bar with the same flange of the post memher, said bars being dimensioned to inclose a relatively large triangular space adjacent the post. i

' 2. An anchored metal fence post of which the main post member consists of a bar having a plurality of longitudinally extending flanges angularly disposed with respect to each other and anchoring elements comprising flat bars secured flat-wise upon two of said flanges which are transversely disposed, said bars diverging upwardly from the lower end of the post and flat tie-bars connecting the upper ends of said divergent bars respectively with the same flanges to anchoring bars forming triangles with vertices meeting in the pointed end of the Post? 7 f V In testimony whereof I have hereunto set my hand at Chicago, Illinois, this 'g'th day of May, 1920.
