Abstract
A track spike (1) with a single or double shaft for wooden ties with spring loop (6), shaft (5) and crosspiece (4). The crosspiece (4), is, in its upper area via a bend (9) of the corresponding shaft portion in the direction of the rail foot (8), offset with resilience relative to the shaft (5). The crosspiece thus engages and retains the rail in position on the tie.
Claims2
A track spike for wood ties having resiliently spaced double shaft portions each with a spring loop and a crosspiece therebetween, each double shaft portion being over relative to a corresponding bore in a wood tie, characterized in that the crosspiece carrying shaft portions are offset resiliently over at most one quarter of their length via a bend of the upper part thereof in a direction toward the corresponding rail foot, the crosspiece thus being maintained in pressure engagement with the corresponding rail foot despite squeezing of the shaft portions together during insertion into their respective bores.
