101. EPPS, WM. JAMES, Maidstone — Inventor.
Machine for throwing flour of sulphur upon horticultural and agricultural crops, for the purpose of destroying the mould or mildew.
The hopper contains the sulphur, and at the bottom is placed a box containing a sieve; through the box is a spindle, attached to a spring and lever outside the hopper, and the whole is fixed before a fan-blower: the brass wheel (which moves the latter) catches the lever attached to the box in the hopper, and causes an oscillating and tapping motion, which sifts the sulphur into the air-chamber of the blower; whence it is blown in one continued cloud with great force.
