THE OOCOANUT PALM.

Improved steam pans, fitted with agitators, so arranged that every 

 part of the pulp or copra is thoroughly separated, and exposed to 

 a temperature varying (according to operator's desire) from 120° to 

 180° Fahr., or higher if required. Valves, cocks, and all other 

 suitable fittings for the discharge of pulp or copra. 



Steam heater for receiving pulp from steam agitator. 



Hydraulic presses for expressing the oil, specially designed for the 

 purpose and of unusual strength, including plates and woollen bags 

 and fibre mats, as may be required. 



Pumps for presses, made in the most improved and superior 

 manner, with all necessary safety and self-acting relief valves, cocks, 

 and mountings, pressure gauge, &c. If required, one set of pumps 

 and gearing may be arranged to work two or more presses. 



Iron tanks for receiving the oil from the presses, of capacity to 

 contain one day's make of oil. A gun-metal pump is employed for 

 raising the contents to large settling tanks. These are generally 

 made of cast iron, in plates of a convenient size, and properly pre- 

 pared for re-erection, with bolts, nuts, washers, &c. 



The settling tanks should be of sufficient capacity to contain four 

 days' produce of oil from the presses, and fitted with the necessary 

 gun-metal test cocks and glass gauges, draw-off cocks, and valves. 



The following estimate of machinery, capable of producing about 

 250 gallons per day, is furnished by Messrs. Priestman Bros., of Hull. 

 In calculating production, 1000 nuts will average 32 gallons of oil :

If it is desired to erect a factory to manufacture both coir fibre 

 and cocoanut oil, one engine can readily be adapted to work the 

 whole of the machines. To drive the machines specified in the fore- 

 going estimate, and also the coir-fibre machines, a 14 horse-power 

 engine would be required for the combined arrangement. The engine, 

 complete with Cornish boiler and all necessary mountings, fittings,
