Buff Dryer.--There are various methods for keeping buffs dry and free
from dust. Some place a sheet of iron against the wall at an angle
sufficient to put a lamp between it and the wall, and then let
the buff rest against the top of the sheet. By this method the buff
is for its full length close to the heated iron, and at the same time
exposed to the heated atmosphere and any dust that may be free.
I would recommend some arrangement by which the buff would be inclosed.
I have found the following to answer the purpose well, which is
a box of sheet iron twenty inches long, eight wide and five high,
with one end left open and the other closed; the cover is made
of the same material, with the edges bent over to go on and off.
There are several wires running through the centre of the sides,
which it is necessary to cover with cloth or paper to absorb
all the moisture that may be made by applying the heat,
and the buffs are put in and taken out at the open end.
In order that the heat may be as nearly uniform as possible, an iron
bar one inch wide, eighteen inches long and one half inch thick,
is so bent that the centre is one quarter inch from the bottom
of the box, and that at least two inches of each end come in contact
with the bottom; this being riveted on the bottom, and a lamp
with a small blaze applied to the centre of the bar of iron.
This will constitute one of the best and cheapest buff dryers in use.
It may be suspended from the wall by placing wires around it,
or it may stand upon legs. Perhaps a more convenient plan is to
place it under the workbench in a similar position to a drawer.
One precaution is necessary: when first heating the dryer,
apply but a very gentle heat. This will prevent an accumulation
of moisture, which would otherwise pass off in steam, coming in
contact with the buff, thus causing a dampness. Another caution:
never have the temperature of the air in the heater more than ten
