Letters .Patent No. 105,98-8, dated August 2, 1870.

IMPROVEMENT IN FENCE-POSTS'.

The Schedule referred to in these Letters Patent and rnking part of the same.

I ,V CHARLES J. SHUTTLEWORTH, of Springville, in the county of Erie .and State of New York, have-in vented a certain new' and improved Fence-Post, of which thefollowing is a' specification.

My invention relates to the construction of a cast metallic point, designed forinsertion in the ground, and the manner of attaching it to the lower end of a wooden post. l j

In the accompanying drawings `Figure I is a side elevation of my improved post complete,

Figure II is a cross-section in line x x,-Fig. I.

Figure III is an enlarged -view of the metallic point detached.

Like letters of reference designate like parts in each of the igures.-

Ais the wooden portionor body of the post, rep` resented square in cross-section,although it may7 be made round, or' of any other suitable form.

. B is the metallic point, castwith four wings 'or ribs b b, at right angles to each other, the widths of which gradually diminish toward the. lower end, so as to give the point a taper forni.

Near the upper end, these wings are connected by a transverse web, c, which serves as braces to stiften4 the wings, and also as a stop to regulate thedepth at which the point is to .be driven in the ground, the web resting on top of the ground, and preventing its further descent.

The point or 'casting B is attached to the post A by cutting two lslits lin the end thereof, ttt/right an-f gies to each other, corresponding with wings b, and then .driving the upper end of the casting therein.

A ring or band, e, is previously'fitted on this divided end of the'post to retain the parts together, while the wings b, near the upper end ot' the casting, nreformed with a rebate or shoulder, d, which stops Vagainst `the lower edge of the band e, and prevents4 :the further passage ofthe wings in the slitted end. of the post,

Thepoint B can be readilycast of the form shown, which is suclras to Venable it to be readily and firmly ksecured to the wooden portion,-while it insures the greatest strength and stiffness with the least amount oi' metal.`

This form of the point adapts it to be readily forced. or driven-in the ground, while the widths of' the wings are sufficient to oppose the necessary resistance to lateral movement after `it has been thus'inserted.

The web c, as before stated, insures the point against being driven too far into the earth7 while the shoulder d retains the band e in place, and prevents the lower end of' the wooden vportion of the post from coming incontact with the ground.

. By this means the Wood is protected from moisture and decay; the metallic point is much more easily driven into the earth than the pointed wooden end of a post, and at the same time Voti'crs, on account of its peculiar construction, a greater resist-ance against lateral movement.

The end of the post A may be made to abut against the web c, or other equivalent stop, but the shoulders d are important and necessary to hold the band e against slipping down in case the post shrinks.

I do not claim combining a cast-iron point with a wooden fence-post, for I am aware that the same is not new,.apd that it is shown in the patent of J Palmer, dated August 9, 1864; but

What I claim as my invention is y The connection of the cast point B tothe wooden part A, by slitting the end ot' the latter to receive the four wings l1 b ofthe former, in vcombination with the band e, shoulders d, and web plate c, as hereinbefore set forth.
