Abstract
Abstract The housing of the drill press is provided with a bit storage compartment. A removable cover plate for the compartment has tabs on its inner surface for detachably holding a drill bit case of the type having two shell sections hingedly connected together with each of the shell sections provided with a rack containing arcuate recesses of progressively increasing size for detachably receiving drill bits of varying diameters. The tabs on the inside of the cover plate are adopted to hold the casing shell sections in their open position thereby to make all of the drill bits accessible upon opening of the cover plate or upon removal of the same from the housing of the drill press. A secondary drill bit holder is detachably and pivotally mounted in the storage compartment for swinging movement back and forth between an access position and a storage position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
167 words
In a power tool of the type having a chuck for receiving drill bits of varying diameters, which drill bits are contained, when not in use, in a casing having first and second shell sections hingedly connected to each other for movement between open and closed positions, wherein each shell section has a series of arcuate recesses of progressively increased size for frictionally engaging respective drill bits of varying diameters, the improvement comprising: (a) a housing portion of said power tool being provided with a cavity in the surface thereof defining a bit storage compartment; (b) a cover plate movably connected to said housing portion for opening and closing said compartment; and (c) said cover plate including first and second sets of tabs on its inside surface for respective, releasable, frictional engagement with said first and second shell sections of a tool bit casing for holding said sections in their open position for storing a series of drill bits in said compartment in a readily accessible configuration.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
42 words
The improvement according to claim 1 wherein said cover plate and said housing portion are provided with respective hinge formations for hingedly connecting said cover plate to said housing portion and for permitting detachment of the cover plate from the housing portion.
Claim 4
Dependent Claim
118 words
The improvement according to claim 1 further defined by: (a) a secondary drill bit holder in the form of a body member configured with a plurality of receptacles of progressively increased size for releasably retaining respective drill bits of varying diameters; (b) said housing portion having opposed wall formations defining a portion of said bit storage compartment; and (c) second hinge means connecting said secondary drill bit holder to said wall formations for swinging movement of said holder back and forth between a storage position in said compartment in contiguous relationship with said drill bit casing when said cover plate is in its closed position and an access position when said cover plate is in its open position.
