Abstract:
Apparatus for sharpening a carpenter's pencil having a wide side and a narrow side so as to obtain a selected profile on one end of the carpenter's pencil, said carpenter's pencil having an axis and a uniform cross section along said axis, said apparatus comprising:a housing defining a first recess having a first opening and having a first pair of convergent walls facing one another within the recess, said housing also having first guide rails extending along said first opening, said housing also defining a second recess having a second opening and having a second pair of convergent walls facing one another within the second recess, said housing also having second guide rails extending along said second opening, a first guide member slidably mounted on said first guide rails, the first guide member defining a first passage therethrough, said first passage being shaped and dimensioned to receive said one end of the carpenter's pencil and to guide the carpenter's pencil for longitudinal motion along the axis with said wide side against the convergent walls when manually actuated by a user, a second guide member slidably mounted on said second guide rails, the second guide member defining a second passage therethrough, said second passage being shaped and dimensioned to receive said one end of the carpenter's pencil and to guide the carpenter's pencil for longitudinal motion along the axis with said narrow side against the second pair of convergent walls when manually actuated by a user, a plurality of blades, each blade having a cutting edge and disposed on one of said convergent walls with its cutting edge extending into one of the first and second recesses, whereby the carpenter's pencil may be pushed alternately through one of the first and second passages of the respective first and second guide members toward the convergent walls while the carpenter's pencil is also being used to slide a first or second guide member to move the end of the carpenter's pencil laterally against the cutting edges of said blades, so as to sharpen the carpenter's pencil to obtain the selected profile.
