RUBBER MANUFACTURE. 123 



WASHING MACHINES. 



The washing machine, Fig. 24, the rollers of which measure 

 9^ in. diameter and 18 in. long, is the smallest size recom- 

 mended by Messrs Francis Shaw & Co. for commercial use. 

 It is supplied with fast and loose pulleys for driving, and the 

 machine and gearing are carried on a strong cast-iron base 

 plate which facilitates erection, and maintains the driving 

 parts in perfect alignment. 



The net weight of this machine is 30 cwt. and the shipping 

 weight 32! cwt. It requires approximately 7 B.H.P. to drive 

 it, and turns out about 800 Ibs. of rubber per day of ten hours. 



Fig. 25 shows a large size pair of breaking-up and creping 

 machines by the same makers. The rollers of these measure 

 12 in. diameter and are 18 in. long. The main line shaft 

 is about 6 in. above the floor level, and carried on the base 

 plates of the machines, but can be placed under the floor if 

 required. 



THE RUBBER FACTORY. 



On the various rubber estates, where large numbers of trees 

 will shortly be coming into bearing, planters should have every- 

 thing in the way of appliances ready to deal with the latex. 



The rubber factory requires special consideration, for unless 

 this be properly equipped it will be impossible to expeditiously 

 treat and despatch the rubber in large quantities. We are 

 indebted to Messrs Francis Shaw for plans of two different 

 factories. 



Fig. 26 is that of a factory for washing, drying, and blocking 

 rubber. The machinery in this consists of a pair of breaking 

 and washing machines which are driven by a semi-portable steam 

 engine, this latter also supplying steam for the drying stove. 

 Provision for three hydraulic presses is also made. 



Fig. 27 illustrates a factory where the machinery for washing, 

 drying, and blocking rubber is driven electrically. There are 

 two breaking and four washing machines, which are capable of 

 an output of 2 tons of either block or crepe rubber per day. 

 The machinery is driven by a 75 B.H.P. motor through a worm
