			From [[Model Steam Locomotives]] by Henry Greenly:

			: Boilers are usually firmly fixed to the frames at the smokebox end, but at the back some scheme must be devised to hold the firebox down to the frames and at the same time permit movement to allow for thermal expansion. The usual method is to fit an angle to the firebox side which rests on the top edge of the frames and to bolt another angle to the latter and lapping over the boiler angle. The design and location of expansion brackets supporting the boiler will depend upon the type of firebox employed. For a boiler with a wide firebox, three-point suspension can be provided at the base of the foundation ring. The front of the ring is supported on a shoe resting on the main frame stretcher, and the rear can be supported on two brackets fixed to the drag plate. (See image)

The longitudinal thermal expansion for the boiler of a 7-1/4 inch gauge <i>Pacific</i> type locomotive is from 1/8 to 3/16 inch according to the temperature of the steam. Provision must also be made for transverse expansion of the firebox in all cases.
