Abstract
A bracing tube construction for pusher type or rocker bar furnaces comprising a bracing tube having a carrier bracket secured thereto. A rider is secured to the carrier bracket and thereby to the tube. The rider has a recess in which the carrier bracket is received and a bore in the rider extends perpendicularly to the tube for receiving a bolt which extends transversely to the tube and is engaged in a groove in the carrier bracket. The carrier bracket has ends engaging corresponding surfaces in the recess in the rider to prevent relative axial movement between the rider and the tube. The bolt and the bore in the carrier bracket are trapezoidal in shape.
