Hook Pulls Snow from Roof
With the easily made device shown in the illustration,
snow can be removed from a roof without dangerous climbing.
Two boards are hinged together and fastened to the end
of a long pole. The "hook" is pushed into
the snow with the boards folded against the pole. When
the contrivance is pulled downward by the operator,
who stands on the ground, the boards extend, and a mass
of snow is shoved in front of them. A length of rope
prevents their spreading too far.
Device for removing snow from roofs: as
the pole is pulled downward,
the boards extend and a large area is cleaned. |
