3. Traveller's Cooker ([Fig. 75]).—This consists of a hot plate with a covered basin permanently attached to it.

4. Electric Coffee Percolator ([Fig. 76]) consists of a hot plate with a coffee percolator to sit upon it. The coffee percolator might sit upon any other hot plate or this hot plate might serve any other purpose, but people do not seem to think of that.

5. Electric Chafing-Dish ([Fig. 77]) consists merely of an electric hot plate with a chafing-dish attached. The electric coffee percolators and chafing dishes require from 300 to 600 watts according to size. If used on the 110-volt current they take about 3 to 6 amperes, and if adapted to the 220-volt current they take from 1½ to 3 amperes, but cost the same to operate in either case. They have connected with them flexible cords and plugs to screw into the lamp sockets.
