Abstract
Abstract A method of fabricating a lamp, wherein the lamp base is made by providing a polyhedral block of wood and cutting the vertical plane faces of the block to form vertically curved sides while still maintaining the straight shape of the faces in the horizontal direction. The lamp shade is made from a plurality of nestable curved panels that are cut from a rectangular parallelepiped block. The panels are placed on a multi-faced form and their vertical edges are joined together to form the shade.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
80 words
A method for making a lamp shade comprising the steps of: providing a rectangular parallelepiped block; cutting a plurality of nestable curved panels of similar shape from said block, said panels having vertical edges and being curved in a vertical direction with straight top and bottom faces in a horizontal direction; providing a multi-faced form; placing one of said multi-faced form; joining the vertical edges of said panels together to form the shade; and removing said form from said shade.
Claim 2
Independent Claim

Claim 4
Dependent Claim
63 words
The method for making a lamp shade as claimed in claim 1, including the steps of removing a portion of said block which is formed when the first of said panels is cut from said block and joining a front planar face of said portion to a back planar face of said block, whereby said portion can be used for cutting additional panels.
Claim 5
Dependent Claim
