FENCE-POST.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed March 3, 1904. Serial IIO- 196,332-

To all whom it may concern:

Be it known that I, GEORGE IRVING GRIees, a citizen of the United States, residing at Flint, in the county of Genesee and State of Michigan, have invented certain new and useful Improvements in Fence-Posts, of which the following is a specification.

This invention relates to improvements in metal fence-posts of the type having a movable anchor.

The obj eot of the invention is to construct a ribbed post with stops at its lower end to support an anchor which is provided with an opening corresponding to the shape of the Many other objects and advantages will be hereinafter referred to and be particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of my improved fence-post with a section of the fence secured thereto. Fig. 2 is a horizontal section on the line 2 2, Fig. 1. Fig. 3 is a similar view on the line 3 3, Fig. 1, looking in the direction of the arrow. Fig. 4 is a sectional view showing the post tilted.

The same numerals refer to like parts in all the figures.

1 represents a post formed with a flat face 2 and an intermediate outwardlypro'ecting rib 3, which extends from one side of t e face 2 and the whole length of the post. The sides 4 of the post taper toward the top. So, also, does the rib 3. This construction obviously assists in anchoring the post in the ground when it is set up and in use. A series of openings 6 are formed in the flat face 2 each side the rib 3 and above the ground-line, while below the ground-line are teats or projections 7, the latter being formed by indenting the metal on one face and forcing it through the other.

9 indicates an anchor, preferably round in plan view and provided with an opening 10 of the shape of the postthat is to say, the opening has a rectangular portion 11, in

which fits the flat face of the post, and a lat eral portion 12 to accommodate the rib 3.

In use the post is placed in its hole and then earth is packed in up to approximately the projections 7, after which the anchor is slipped over the top of the post and drops down and is supported on the packed earth.

Earth is now packed in the hole and on top the anchor to the level of the ground. A decidedly efiective means is thus cheaply provided for anchoring the post and at the same time preventing frost getting to the metal below the anchor.

By reason of the taper of the post it is normally held in the ground when the earth is packed around it; but as there is not surface enough in contact with the earth to take proper hold the post soon tilts under the strain of the weight of the fence. However, when the anchor is supplied this difficulty is overcome, as the flat surface of the anchor is quite sufficient to obtain a purchase and maintain the post in an erect position, so that I not only provide the tapering sides to steady the post, but use the anchor to coact with this specific construction to positively resist the strain of the weight of the wire, and thus insure against the fence sagging.

I have specifically described the shape of the post,which I regard as quite essential, inasmuch as it affords a substantial means for taking the strain and at the same time allowing of a light and durable constructionthat is to say, that should the post have a tendency to lean in the direction of the arrow A the flat face 2 would bind hard against the upper edge 13 of the slot and the rib 3 would likewise bind against the lower edge 14 of the portion 12 of the slot. In such a case the flat face becomes a brace for the rib, whereas if the leaning of the post should be in the reverse direction the opposite edges 15 and 16 would act on the respective face and rib and the latter becomes the brace for the former. Like weaknesses may be overcome in the endwise leaning of the post, the edge of the flat face receiving the strain and acting as a brace and distributing it throughout the post structure.

What I claim as new is 1. A fence-post having a series of projections formed by indenting the metal and forcing same outwardly, and an anchor having an opening of the shape of the post and larger than the cross-sectional area of the same when supported by the projections, whereby the anchor will be raised freely on the post and away from the projections when influenced by the frost.

2. A fence-post having a series of projeoname to this specification in presence of two tions formed by indenting the metal and forc- Witnesses. ing same outwardly, and an anchor having an opening of the cross-seotiona1 shape of the GEORGE IRVING GRIGGS' 5 post, said anchor being supported by the pro- Witnesses:
