VacHunter Gallery - Wheel
|
In their day, wheel operated vacuums approached the cutting
edge of early technology. They exhibited a sophistication that was
not present in earlier vacuum designs. This style of machine
provided powerful and continuous suction for its user. The increase
in vacuum even allowed for larger diameter hoses and bigger cleaning tools.
Typically, one person cranked the wheel while another cleaned with a wand
or hand tool.
Mechanical
advantage was achieved through the use of belts and pulleys. The hand,
or power wheel, was set into motion with a cranking handle. The large
wheel drove a belt that also went around a much smaller pulley. The
small pulley was fixed to a shaft which would spin a fan or pump a set of
bellows. These machines were used effectively until the early electric
vacuums became popular.
