Abstract
A juicer attachment which can be latched onto a motor housing includes an upper cover and a lower cover attached to said upper cover to define a gear chamber. The drive for a rotary straining and juicing basket includes telescopically engaged upper and lower drive shafts with spaced heat dissipating bushings and speed reduction gears in the gear chamber. At least one spring biases at least one drive shaft upwardly to normally disengage at least two gears in the chamber so that the motor can be left running while the rotary parts of the juicer attachment remain stationary.
Claims23
A juicer attachment for mounting on a housing containing a motor having a rotary drive shaft, said attachment comprising:
- a) an upper cover having a side wall and a bottom wall having an aperture for receiving a drive shaft;
- b) a lower cover having an aperture for receiving a drive shaft, said lower cover being attached to said tipper cover, said upper and lower covers defining a gear chamber;
- c) an upper drive shaft slidably mounted in said aperture in said upper cover;
- d) a rotary straining and juicing basket supported on said upper drive shaft in said upper cover,
- e) a lower drive shaft telescopically engaged with and rotatable relative to said upper drive shaft, said lower drive shaft having a drive coupling thereon for engaging a drive coupling driven by a motor;
- f) spaced shaft bushings between said lower drive shaft and said upper drive shaft and a heat dissipating cavity between said bushings;
- g) gears in said gear chamber for transferring power from said lower drive shaft to said upper drive shaft;
- and
- h) at least one spring biasing at least one of said upper anti lower drive shafts upwardly relative to said covers to normally disengage at least two gears in said chamber.
(canceled)
An electric juicer comprising:
- a housing containing an electric motor having a rotary drive shaft extending upwardly from said housing and a juicer attachment affixed to said housing, said juicer attachment including:
- a) an upper cover having a side wall and a bottom wall having an aperture for receiving a drive shaft;
- b) a lower cover having an aperture for receiving a drive shaft, said lower cover attached to said upper cover, said upper and lower covers defining a gear chamber;
- c) an upper drive shaft slidably mounted in an aperture in said upper cover;
- d) a rotary straining and juicing basket supported on said tipper drive shaft in said upper cover,
- e) a lower drive shaft telescopically engaged with and rotatable relative to said upper drive shaft, said lower drive shaft having a coupling thereon for engaging a drive coupling driven by said motor;
- f) spaced shaft bushings between said lower drive shaft and said upper drive shaft and a heat dissipating cavity between said bushings;
- g) gears in said gear chamber for transferring power from said lower drive shaft to said upper drive shaft;
- and
- h) at least one spring biasing at least one of said upper and lower drive shafts upwardly relative to said covers to normally disengage at least two gears in said chamber, said motor drive shaft being coupled to said lower drive shaft.
