ISAAC HAWS, OF HANNIBAL, NEW YORK.

FENCE-POST.

SPECIFICATION forming part of Letters Patent No. 745,606, dated December 1, 1903.

Application filed July 31, 1902. Serial No. 117,871. (No modem To all whom it may concern..-

Be it known that I, ISAAC HAWs, a citizen of the United States, residing at Hannibal, in the county of Oswego and State of New York, have invented certain new and useful Improvements in Fence-Posts, of which the following is a specification.

My invention relates to improvements in concrete or cement posts for the construction and support of wire, picket, or board fences; and its objects are, first, to provide a post with which staples or nails may be used and removed or renewed without materially deterioratin g the post; second, to provide acoucrete post with which the nail-receiving ele-- ment may be renewed when necessary, and, third, to provide for reinforcing and strengthening the post in such a manner as to reduce the danger of breaking them to the lowest possible ratio consistent with the symmetry of form and proportions desirable in concrete posts, and to utilize the smallest possible amount of concrete consistent with a post that will meet the necessary demands of the trade. I attain these. objects by the construction illustrated in the accompanying drawings, in which- Figure l is a front elevation of the post. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a back elevation of the same. Fig. 4 is a transverse section of the same on the line at a; of Fig. 3, and Fig. 5 is a twist of Wire, showing how the reinforcing-wire is con.- structed or prepared.

Similarletters refer to similar parts through out the several views.

A represents the concrete portion of the post. B represents a thin narrow strip of board that is tapered or chamfered at the edges and top to embed into the concrete and form a dovetail connection therewith, so that it will be impossible for it to drop out of the concrete, the chamfering of the upper end being for the purpose of averting the possible danger of water percolating between the wood and the concrete and tending to destroy the wood by rot, 850. It will be noticed that thelower end of the wood is chamfered the other way, which I prefer, as it wholly averts the danger of water settling in the concrete below the wood and rotting the wood.

My means of reinforcing and strengthening the post consists, first, in enlarging the concrete portion at a at or about the surface of the ground, (indicated by the dotted lines, 3/ 1,) and, second, in the insertion of a twisted wire C in the concrete longitudinally of the post near the front and the back surfaces of the post. The placing of the wood B into the concrete with a dovetail joint, as shown,

tends also to greatly strengthen the concrete portion of the post.

My appliance for enabling me to renew the wood when it has become deteriorated by the frequent driving of nails or staples into it or by rot or otherwise is to pierce the concrete post with several apertures, as b b b in Figs. 1 and 3, so that bolts may be passed through the concrete and through the renewed piece of wood to solidly bolt the wood to the concrete, as indicated at D in Fig. 2.

The dovetailed piece of wood can only be removed by splitting it fine and removing it in pieces and can only be replaced by a square-edged strip fitted to enter the groove and held in place by bolts, as hereinbefore described, though the dovetailed edges of the groove may be filledwith detached triangular strips, if desired. I

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

1. In combination with a concrete post, a narrow strip of wood dovetailed longitudinally into the surface of the post and a down- .wardly-chamfered joint at each end thereof,

ISAAC HAWS.
