The "tip ups" and the "jumping jacks" serve their purpose
nicely, but a more elaborate device is the electric signal. A
complete electric outfit can be installed in a box and carried as
conveniently as tackle.
An ordinary electric bell, A, Fig. 1, having a gong 2-1/2 in. in
diameter, and a pocket battery, B are mounted on the bottom of the
box. The electric connection to the bell is plainly shown. Two
strips of brass, C, are mounted on the outside of the box. The
brass strips are shaped in such a way as to form a circuit when
the ends are pulled together. The box is opened and set on the ice
near the fishing hole. The fish line is hung over a round stick
placed across the hole and then tied to the inside strip of brass.
When the fish is hooked the line will pull the brass points into
contact and close the electric circuit.
** Homemade Floor Polisher [10]
A floor polisher is something that one does not use but two or
three times a year. Manufactured polishers come in two sizes, one
weighing 15 lb., which is the right weight for family use, and one
weighing 25 lb.
A polisher can be made at home that will do the work just as well.
