ABSTRACT:
Rail track heaters, comprising metal sheathed electric heaters, adapted to be positioned for heating a third rail or a switch rail. Our invention includes a simple stamping to provide a bracket for holding a cover containing the heater and surrounding insulation in position on the rail, and the same type of bracket made to be used to hold the terminal assembly of the heater in position on the rail. Each of the brackets is firmly held to the rail by a bolt extending transversely of and underneath the rail, the bolt having a hook at one end to hook over an adjoining part of the rail flange at one side of the rail, and having its other end adapted to engage a bracket part at an adjoining portion of the rail flange at the opposite side of the rail.
