JACOB BRINKERHOFF, OF AUBURN, NEW YORK.

IMPROVEMENT IN METALLIC FENCE-POSTS.

Specification forming part of Letters Patent No. 189,918, dated Apri124, 1877 application filed March 16, 1877.

To all whom it may concern Be it known that I, JACOB BRINKERHOFF, of Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Metallic Fence-Posts and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to metallic fence-posts and it consists in a sheet-metal fence-post 'having its base gradually twisted; also, in providing such base, or the base and post, with a longitudinal corrugation; also, in providing such post with slits or slots to receive the band or fence rails 5 and, further, in cutting the flanges at the lower end of-the base, and bending them outward in opposite directions, all as hereinafter more fully set forth.

In the annexed drawing, Figures 1 and 2 are front views of my improved metallic fencepost. Fig. 3 is a side view thereof. Fig. 4

shows the base only.

A represents a fence-post, made of a single piece of sheet metal of suitable dimensions. The lower end of this post, which forms the base B, is gradually twisted either to the right or left, more or less, as desired, so that when set in the ground the earth holds it down. By this twisted form of the base, it will also be seen that the base presents a Hat surface on all sides, so that in whatever direction any strain may be put on the post, such strain or pulling will be against a broad, fiat surface, and the post cannot be pulled over in any direetion.

To increase the strength and stiffness of the fence-post, one or more longitudinal corrugations, a, are formed in the sheet metal,

and such corrugation or corrugations may extend the length of the base only, or the entire length of the base and post, as may be desired.

In one or both of the edges of the sheetmetal post A is formed a series of slits or slots, 11, to hold the band or fence rails 0. These slits or slots are preferably made L-shaped,

as shown, but may be of any suitable form to receive and hold the band-rails G.

By the above construction of fence-post it is rendered firm and durable, and can yet be,

sheet-metal fence-post. These lips 12' b may be attached to the base of the post, if desired, instead of being formed thereon.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A sheet-metal fence-post having its base gradually twisted, substantially as and for the purposes herein set forth.

2. A sheet-metal fence-post having its base twisted, and provided with one or more longitudinal corrugations extending the entire length of the base, substantially as herein set forth.

3. A sheet-metal fence-post having a twisted base, and provided with one or more longitudinal corrugations through the post and base, substantiallyas and for the purposes herein set forth.

4. A sheet-metal twisted fence-post having one or more longitudinal corrugations, and a series of slits or slots in one or both of its edges, substantially as and for the purposes herein set forth.

5. A sheet-metal fence-post provided at the lower end of its base with lips I) b, projecting outward in opposite directions, as set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

JACOB BEINKE' HOEE.
