366 COALFIELDS AND COLLIERIES OF AUSTRALIA. 



without transmitting any effect, beyond a purely rotative one. 

 These motors are not run at their full capacity. Later on, 

 when the speed of the fan has to be increased, only one motor 

 will be used, the other being held in reserve, in case of a 

 breakdown. 



There are two three-throw pumps, Tin. by Gin., also a 

 small 2iii. three-throw pump, all electrically direct driven. 

 These are mounted on trollies, so that they can be hauled about 

 from one place to another. When the lift becomes too great 

 for these pumps, a turbine pump, now on the ground, will be 

 installed at a permanent sump, from which it will pump to the 

 surface. 



The horses employed below are stabled at the surface, 

 where there is accommodation for 32 animals. 



At the pit top, after weighing, the skips are run into a 

 side tumbler, of which there are two, the full skips pushing the 

 empty one oft' at the other end. The coal falls into a shaking 

 screen made of four plates, in which there are oblong holes. 

 The large coal falls on to a picking belt, and then down a 

 shoot into waggons. The shoot has a swing door, which is let 

 down while nlling the waggons ; this not only bridges the space 

 between the shoot and the waggon, but does away with the 

 necessity of stopping the picking belt while changing wag- 

 gons. The slack falls into a small coal hopper, from which it 

 is elevated along a trough to a slack box. Out of this box the 

 fuel for the boilers is drawn, and the miners get their monthly 

 allowance of one ton per man. There is a slide door at the 

 bottom of the trough, where it passes over a line of rails, so 

 that waggons can be loaded with slack as required. Any dirt 

 brought out of the mine is tipped into a dirt box from an end 

 tippler. The side tumblers are set in motion by a man who, 

 by pressing on a lever with his foot, forces a revolving pulley 

 t\ gainst the rim of the tumbler. 



The boiler house contains four Lancashire boilers ; they are 

 30ft. long, and each tube is 3ft. 3in. in diameter. The boilers 

 are made for a working pressure of 1201bs. of steam, and are 

 each rated at 300 h.p. Two of the boilers were made by Groni- 

 nan and Co., and two by J". Thompson, of Wolverhampton. Ar- 

 rangements are made whereby the clampers can be manipu- 

 lated from the front of the boilers. The water is fed in by two 

 Smith, Vaile pumps. 



The power-house encloses two sets of Bellis-Morcoin high 

 speed engines, each direct coupled to a 100k. w. British Thomp- 

 son Houston 6 pole, 250 volt generator. 



A stump cabin has been erected by the company, in which 

 the men can pay their dues to an officer of their union.
