Claim 1
Independent Claim
133 words
A pencil sharpener comprising, in combination: (a) a body having a conical cavity therein, the cavity extending longitudinally of the body and defining a large opening at a first face of said body, for receiving the tip of a pencil; (b) a slot for receiving a cutting blade being provided in the wall of said conical cavity adjacent a generally flat outer base section forming a part of the body and supporting a flat sharpening blade such that a sharp edge thereof protrudes partly into and along the cavity with the sharpening blade disposed generally tangentially to the wall of the cavity; (c) an elongate mounting piece fixedly secured to an outer surface of the body and protruding therefrom in a direction generally transverse to the direction of the axis of said cavity.

A pencil sharpener as claimed in claim 1 or claim 2, wherein the mounting piece is a flat first leg portion of a generally U-shaped springy clip whose second leg portion resiliently overlaps the first leg portion and merges with same at a yoke section wrapped around the body of the sharpener and is fixedly secured to same.
Claim 5
Dependent Claim
86 words
A pencil sharpener as claimed in claim 1 or claim 2, wherein the mounting piece is a first leg portion of a generally U-shaped springy clip whose second leg portion resiliently overlaps the first leg portion and merges with same at a yoke section wrapped around the body, said first leg portion being provided with a passage for a mounting screw and said second leg portion being provided with an access cutout complementary with the passage, to facilitate manipulation of a screw passing through said passage.
Claim 6
Dependent Claim
136 words
A pencil sharpener as claimed in claim 1 or claim 2, wherein the mounting piece is a first leg portion of a generally U-shaped springy clip whose second leg portion resiliently overlaps the first leg portion and merges with same at a yoke section wrapped around the body, said first leg portion being provided with a passage for a mounting screw and said second leg portion being provided with an access cutout complementary with the passage, to facilitate manipulation of a screw passing through said passage, said first leg portion being of a size complementary with the size of a leg portion of a clip of a predetermined type or types of the housing of a measuring tape, whereby the sharpener can be secured to such housing in lieu of an existing clip of the housing.
Claim 7
Dependent Claim
