All the engines listed on opposite page have girder beds, supported cylinders, and generally embody our very latest improvements.
Balance weights are fitted to all crank shafts, and wrought-iron splasher guards are likewise provided.
Standard wrought-iron pulleys as per list are included, but special pulleys are charged extra.
The powers given are maximum at the standard speeds, and due allowance should be made between this maximum and the constant working load which the engine has ordinarily to meet, so as to ensure a suitable reserve of power.
So far as power developed and good general working are concerned, it is assumed that the local conditions are not unusual. The gas supplied to the engine should in all cases be plentiful and good. There should also be a plentiful supply of water for the cylinder jacket.
In cases where slower running engines are preferred, all those listed above are equally suitable when running at reduced speeds. In the latter case, the power developed will be reduced in proportion to the drop in speed.
Where gas engines work at a considerable elevation above sea level, their power is reduced about 5 per cent, for every 1,000 feet.
Our standard normal engines listed on p. 41 will drive lineshafting with a suitable degree of steadiness for most industrial purposes, but we do not guarantee that these engines will necessarily give a sufficiently steady drive for electric work. For the latter we advise our special electric type engines.
