IMPROVEMENT m PosTs FOR TELEGRAPH-S, 800-.

Specification forming part of Letters PatentNG. 5,781, dated September 19, 1818.

To all whom it'may concern:

Be it known that I, HENRY.G.-HALL, .ot' Kigkersville, in the county of Licking and State of Ohio, have invented a new and'useiul improvement in the construction of telegraph-posts to prevent rotting at the'surface' of the ground into which they are erected, which is described as 'follows, reference being had to the annexed drawings of the same,making part of this specification.

Figure l is aside elevation of part of a telegraph-post with the improvement attached. Fig. 2 is a vertical section through the center of the same. Fig.3 is aside elevation of amodification of theimp'rovement. Fig. 4 is a vertical section of the same. Y

The nature of .this invention and improve. ment consists in preven tin gthe posts supporting magnetic-telegraph wires from rotting at the surface of the groundxbyforming on their lower ends shanks or tenons and inserting the same into sockets formed in castiron shoes, made flaring and sharp-on their upper or concave ends to allowthem to bedriven into shoulders on the posts, which are of greater diameter than the shoes, in order to overhang and protect them andpreventthe water get ting into the shoes at the joints, said sockets or eoncavities beingv made of greater depth than the length'of the tenons, in order to leave spaces between their bottoms and ends of the tenons after the shoes are driven on the same, and thus allow them to be driven farther on when required. j

The telegraph-post A, Figs. 1 and 2,-has a circular tenon, B, formed on its lower end, which is inserted into a corresponding socket formed in a circular shoe, (J, bound near'its upper end with. a fillet or band, E, for strength- ,enin g the same. The shoe is made flaring and.

sharp at its upper or concave end, E, and is driven on the tenon or shank of the post by percussive foreeapplied to its lower end, orin any convenient manner, until the-said flared. and sharp edge penetrates the shoulder formed by the tenon suflieie'ntly far to secure the post and shoe firmly together and form a barrier to prevent the entrance of water between'the socket and tenon, the projecting shoulder s also assisting in this last-mentioned object, as

before stated. After the shoe is firmly secured similar totho'se previously described, and represented in Figs. 1 and 2.

Instead of making the'sh-oes ot'cast-iron, as described, they may be made of stone or any other suitable material, or of clay molded, dried,

and baked in a kiln, the fillet being cast with the shoe. 7

' I do not claim shoeing the ends of wood posts or poles with honor stone to prevent rotting; but 1 What I do claim as my invention, and desire to secure by Letters Patent, 'is- The manner of combining the cast-iron or artificial-stone shoes 0 with the'posts A-by casting the shoes with sockets of adepth greater than the length of the tenons Ben the lower endsof the posts to be'inserted into said sockets, and with fillets or bands 1) around the external surfaces to strengthen the concave ends E, which are also made flaring and sharpso as to'be forced Into the shoulders s of' the posts, which are to be of greater diameter thanthe shoes'in order to overhang and protect them and to prevent the .water getting into the shoes at 'thejoints.

In testimony whereof I'have hereunto subscribed my name before'two witnesses this 5th day of August,18 4.7.
