- a base having a bottom surface adapted for being supported by a horizontal surface;
- a cutting assembly mounted to the base and projecting upwardly therefrom;
- a cage disposed above the base and having an upper portion surrounding the cutting assembly, said upper portion of said cage defining a plurality of radial chutes and having an upper cover portion defining an opening for insertion of an end of a pencil;
- and
- a receptacle surrounding said cage and disposed above said base for collecting the shavings from sharpening a pencil.
A pencil sharpener comprising:
- a base having a bottom surface adapted for being supported by a horizontal surface;
- a cutting assembly mounted to the base and projecting upwardly therefrom;
- a cage disposed above the base and having an upper portion surrounding the cutting assembly, said upper portion of said cage defining at least one radial chute and having an upper cover portion defining an opening for insertion of an end of a pencil;
- and
- a receptacle surrounding said cage and disposed above said base for collecting the shavings from sharpening a pencil, wherein the receptacle is vertically displaceable from the base for discarding the shavings.
A pencil sharpener comprising:
- a base having a bottom surface adapted for being supported by a horizontal surface;
- a cutting assembly mounted to the base and projecting upwardly therefrom;
- a cage disposed above the base and having an upper portion surrounding the cutting assembly, said upper portion of said cage defining at least one radial chute and having an upper cover portion defining an opening for insertion of an end of a pencil;
- and
- a receptacle surrounding said cage and disposed above said base for collecting the shavings from sharpening a pencil, wherein the receptacle comprises an outer wall, an inner wall and an annular floor panel extending radially between the outer and inner walls, the inner wall extending axially only a portion of the axial extent of the outer wall.
A pencil sharpener comprising:
- a base including
- an upper rim and
- a bottom surface adapted for being supported by a horizontal surface;
- a cutting assembly mounted to the base and projecting upwardly therefrom;
- a cage disposed above the base and having
- a lower portion extending a height from the base upper rim,
