The disclosed connection bar is elongated, adatped to overlap respective adjacent ends of two rails, and the top and bottom portions at each end of the bar have elongated contact faces shaped to cooperate flush against respective surfaces on these rails. A pair of holes is provided in a web portion of the bar, and securing devices may be extended through the holes for clamping the bar against the rails. An elongated reinforcing rib may be formed on the web portion, extended across the bar transverse to and between the enlarged top and bottom portions, and located to line up adjacent the ends of the rails when the bar is secured to the rails. Other reinforcing ribs may also be extended across the web portion, transverse to and between the top and bottom portions; and these other ribs are located outwardly beyond the holes. The bar may be formed by forging a hot billet of forgeable material between a set of dies having faces that complement respectively the rail and remote sides of the intended bar, the dies being moved toward one another at a high relative velocity to strike the interposed billet with a high impact, sufficient after repeated strikes to shape the billet to that intended for the bar including having the rail-engaging contact faces.
A method of forging a bar for overlapping and connecting the ends of aligned railroad rails disposed in end-to-end relation, said bar being elongate and of finite length, including a rail side and a remote side, said bar including an enlarged top portion having a contacting face on said rail side extending axially along the length of said bar for contacting a rail, an enlarged bottom portion having a contacting face on said rail side extending axially along the length of said bar for contacting a portion of a rail in spaced relation to said contacting face on said top portion, and a connecting web portion, said method comprising the steps of:
A method of forging a bar for overlapping and connecting the ends of aligned railroad rails disposed in end-to-end relation, having a rail side, a remote side and a finite length formed by the steps of:
