THERE are many uses for an electric
oven of the industrial type in small
shop and laboratories, where moderate
baking temperatures, accurately controlled,
are necessary. Small parts, Which
have been painted or lacquered often require
baking. Damp or wet pieces of equipment
may require drying out. Windings,
after dipping in insulating varnish, need a
certain amount of baking. Then too, an
oven may be required in laboratory work
of a special nature. The oven illustrated
was built in an electrical engineering
laboratory and has proven invaluable.
Measuring 24×18x16 in., this oven is small
enough to be used on the bench, yet it will
accommodate quite a bit of work. Heat is
provided by two 350 watt strip heaters,
which are mounted to the inside surface of
the oven, at each side and quite near the
bottom. Control is provided by a Fenwal
Thermoswitch, which is mounted on the
end of the oven. This device has a brass
140
tube projecting into the oven space in
which thermal contracts are built. With an
arrangement of a dial and knob, as shown,
it is possible to accurately control a range
of settings to 400 degrees Fahrenheit.
The material used for the sides, top and
bottom of the oven is ΒΌ in. asbestos-cement
board, known as Transite. Angle iron
is used as a framework and the cover is
equipped with strap hinges and a wire pull
handle.
