powerful to clear the ashes and that the fall of the

ashes from the smokebox bottom to the ejector is

facilitated by an easy sloping path. The steam jet nozzle

should be protected from becoming clogged up with falling

ashes, when not in use. The discharge pipe is to terminate

in a flange fitted with a hinged lid, wing-nut and bolt.

The steam jet is to be operated by a steam cock suitably

fitted on the firebox back plate.

Chimney & Petticoat Pipe. The chimney is to follow the

same design as shown on Drg.No.Z.4472/39, Regn.No. 251/1,

and is to be fitted with a brass cap at the top.

Hulburd's Rings. The section of Hulburd's copper jointing rings as shown at item N on Drg.No.Z.4472/136, Regn. No. 251/1 is to be retained for the dome joint front cylinder- cover joints, and mud-collector joints, etc.

Boiler Feed Arrangements. Each engine is to be fitted with

a Worthington-Simpson Feed Water Heater and Boiler Feed

Pump, placed if possible between the frames under the

boiler barrels, if this position is not found to be

practicable, it is to be fitted in an accessible position

on the left-hand side of the engine in such a manner as

not to obstruct unduly the driver's view. A Gresham &

Craven No. 10 Injector with "Simplex" cones is also to be

fitted under the foot-step on the right-hand side, all as shown on Drgs.Nos. 2.4472/61 /62 and /58, Reqn.No. 251/1.

The particular drawings in the "as made" sets relative

to the Pump and Heater are to show distinctly the fullest

particulars both in arrangement and detail for information and guidance in operation. To facilitate dealing with

the ordering of spare parts for the pump and heater installation, the whole of the component parts should be properly scheduled and named as shown on Drg. No.Z.4472/ 62A, Regn. No. 251/1.
