发明名称 Cast shoulder
摘要 A support for an elastic rail clamp comprising two legs which are adapted to the above the rail tie surface adjacent the rail flange. The rail clamp is oriented at right angles to the longitudinal dimension of the rail and has two free arms which lie on the rail flange. To prevent accidental removal of the rail clamp from the support the support includes in the face adjacent the rail flange a channel for each arm to pass through when moving onto or off the rail flange. This provides a raised portion of the support between the two arms of the clamp. The support is also designed to ensure that contact points between the rail clamp and the support are minimal to reduce the incidence of corrosion bonding.
