4,000 litres of air. The only attention which it is necessary to give to the apparatus is to charge with gasoline 

 from time to time and wind the weight up, this in most cases only being requisite once a day; if the fall of the 

 weight can be increased the weight needs to be raised less often. Even when the apparatus is working the 

 weight can be wound up without disturbing the generation of the gas. 



The driving weights are only supplied when expressly asked for, as they can generally be obtained more 

 cheaply on the spot. A pump No. 50,568 is necessary and the liquid for preventing freezing desirable. (Also 

 the signalling device No. 50,570.) 30 m wire. rope are given in with the apparatus as also the driving chain and 

 handle for winding up the weight; if the height through which the weight drops is increased a correspondingly 

 larger quantity of wire rope should be ordered extra.

*) When ordering, in addition to quoting the list number, please state the letters a, b, c, etc. placed before 

 the price line. 



The prices quoted above include the gas engine with heavy fly wheel, suitable for electric light work, 

 external bearings, gas bag, tools and spare parts. The engines have tube ignition and guided valve motion. 



Packing is charged separately, as is also erecting and the pipe lines which may be necessary. It is advisable 

 to order a non -return starting handle, as when this is used it is not necessary to start the engine by turning the 

 fly-wheel. 



If the gas is taken from a light supply, it is desirable to provide a gas pressure governor so as to obviate 

 any flickering of the lamps. The water necessary for cooling can be taken off the water supply; if water is not 

 laid on, a cooling tank to fit in with the size of the motor should be ordered. 



In working the above engines with gasoline, the use of magneto ignition is recommended instead of the 

 tube ignition; this entailing an increase of price in the case of the 1 6 HP. motors of 10. The output of the
