PIPING AND HOODING EXHAUST FANS FOR MILL USE. I Almost every planing mill or wood-working sctory of the present time uses the exhaust fan or the purpose of taking the shavings and dust rom the machines and depositing same in a uitable shavings vault near the boiler room, .'here they are used wholly or in part for fuel, n many factories, writes "G. T. ; in the /Vood Worker, this system does not give full atistaction, and is a constant source of trouble ind expense. While some mills gee fairly good results, it is usually at great expense of power ind consequent cost of fuel, as well as the tontinual patching up of pipes, hoods and minor roubles. In every case where the fan does not vork properly you can trace the trouble either !o the imperfect way in which the pipes from the machines to the fan are rigged, the wiong method of hooding around the cutter heads, or n the way that pipes from the machine enter the main pipe. ! There is no good reason why an exhaust fan should not work satisfactorily as any machine in rhe shop. If the fan is of suitable size and properly piped to the machines it will not cause any more expense, over the usual wear and tear <br the work it does, than other machines. A nan would be considered a fool who tried to make a pony do the work of a horse, or to carry [ja ton of coal in a light buggy, or if he used a part horse for a trotter and a coal cart for a road wagon, although he could do the latter with better results than the former. So it is with the fan. ilYou can't expect a small fan to do good work beyond its capacity. A too large fan is equally as bad, as it uses power that could be better employed, for the average mill, especially where heavy planing is done, is usually short on power.
