Abstract
Abstract Tool holder having a row of spaced tool supporting sockets each adapted to receive and support in an upright position therein the shank portion of one of a series of drill bits of increasing diametrical size from one end to the other end of the row. The tool holder includes a second row of tool supporting sockets spaced from the first row and adapted to receive and support in an upright position therein the shank portion of one of a series of thread cutting taps of increasing diametrical size from one end to the other end of said second row. Indicia are provided which extend from each tap socket toward a predetermined correlative pair of spaced drill sockets. Each such pair of drill sockets is adapted to retain therein the proper tap drill and clearance drill for each corresponding tap.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
218 words
Tool holder for a plurality of taps and a plurality of drills disposed therein comprising means for holding said taps in a predetermined succession according to the diametrical size of said taps, means spaced from the succession of taps for holding said drills in a predetermined succession related to the diameter thereof, each of said tap and drill holding means being adapted to receive and hold a drill and tap of a given size, and indicia which lead from each tap holding means toward a pair of adjacent drill holding means adapted to hold drills of different diametrical size, one of said pair of drills being the tap drill for the tap from which one of said indicia leads and the other of said pair being the clearance drill toward which the other of said indicia leads, said indicia including adjacent pairs thereof which extend toward each of a plurality of said drill holding means in converging relation, each drill holding means toward which said indicia extend in converging relation being adapted to hold one drill of the proper diametrical size to serve as both the clearance drill for one of said taps and the tap drill for the next successive size tap whereby a plurality of said drills are dual functional for use with successive size taps.
Claim 2
Dependent Claim
218 words
Tool holder for a plurality of taps and a plurality of drills disposed therein comprising means for holding said taps in a predetermined succession according to the diametrical size of said taps, means spaced from the succession of taps for holding said drills in a predetermined succession related to the diameter thereof, each of said tap and drill holding means being adapted to receive and hold a drill and tap of a given size, and indicia which lead from each tap holding means toward a pair of adjacent drill holding means adapted to hold drills of different diametrical size, one of said pair of drills being the tap drill for the tap from which one of said indicia leads and the other of said pair being the clearance drill toward which the other of said indicia leads, said indicia including adjacent pairs thereof which extend toward each of a plurality of said drill holding means in converging relation, each drill holding means toward which said indicia extend in converging relation being adapted to hold one drill of the proper diametrical size to serve as both the clearance drill for one of said taps and the tap drill for the next successive size tap whereby a plurality of said drills are dual functional for use with successive size taps.
Claim 3
Dependent Claim
42 words
Tool holder for a plurality of taps and a plurality of drills disposed therein as set forth in claim 1 in which said indicia extending from each tap holding means toward a pair of successive drill holding means are of contrasting appearance.
Claim 4
Dependent Claim
75 words
Tool holder for a plurality of taps and a plurality of drills disposed therein as set forth in claim 2 in which said holding means comprise spaced sockets adapted to receive therein the shank portions of said drills and taps, said sockets being of increasing diametrical size arranged in first and second spaced rows, the first row containing taps of sequentially increasing diametrical size and the second row containing drills of sequentially increasing diametrical size.
Claim 5
Dependent Claim
66 words
Tool holder for a plurality of taps and a plurality of drills disposed therein as set forth in claim 3 in which said sockets extend into a base panel of the tool holder and in which said indicia are imprinted on the base panel, and adjacent pairs of said indicia extending in diverging relationship from each tap socket toward a predetermined spaced pair of drill sockets.
