It isadapted to both steel and wooden cars and to wooden and mal-leable-iron draft sills, the arrangement for wooden sills beingillustrated in the accompanying engraving. The essentials are sill plates, stop bars and followers. Thesill plates are gained into the draft timbers to a depth of l7/8ins. and secured to them by four bolts each. Each sill plate hasa lip at each end, gained into the draft sills, giving four pointsat which the stresses are received. The length of the sill ins., distributes the strains over a large area, and they arenot concentrated at any one point. Their length also rendersthe frictional resistance between the plates and the sills impor-tant. The stop bars are rectangular and are cast with an openingthrough the c
