Abstract
An air compressor includes a cylinder attached to the base, two or more motors selectively secured to the base and each having a spindle extended through the base. The motors may include different driving powers or different diameters. Two coupling devices may couple the spindles of the motors to the cylinder respectively. A smaller motor includes a pinion secured to the spindle and engaged with a gear, and a weight is secured to the gear and coupled to the cylinder. The spindle of a greater motor may be secured to the weight which is then secured or coupled to the cylinder.
Claims19
An air compressor assembly comprising:
- a base,
- a cylinder attached to said base,
- a first motor selectively secured to said base and including a spindle extended through said base,
- a first coupling means for selectively coupling said spindle of said first motor to said cylinder,
- a second motor selectively secured to said base and including a spindle extended through said base, and
- a second coupling means for selectively coupling said spindle of said second motor to said cylinder.
An air compressor assembly comprising:
- a base including an aperture and an orifice formed therein,
- a cylinder attached to said base,
- a first motor selectively secured to said base and including a spindle extended through said aperture of said base,
- a first coupling means for selectively coupling said spindle of said first motor to said cylinder,
- a second motor selectively secured to said base and including a spindle extended through said orifice of said base, and
- a second coupling means for selectively coupling said spindle of said second motor to said cylinder.
An air compressor assembly comprising:
- a base including an upper portion and a lower portion,
- a cylinder attached to said base,
- a first motor selectively secured to said upper portion of said base and including a spindle extended through said upper portion of said base,
- a first coupling means for selectively coupling said spindle of said first motor to said cylinder,
- a second motor selectively secured to said lower portion of said base and including a spindle extended through said lower portion of said base, and
- a second coupling means for selectively coupling said spindle of said second motor to said cylinder.
