Abstract
Abstract Quick change chuck systems with integral fluid inducer. A quick change drill bushing system reduces misalignment of bushing to motor spindles and enables rapid change of cutting tools and bushing thereby reducing the number of dedicated working systems. The quick change chuck system with integral fluid inducer may utilize a quick change nosepiece system in combination.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
159 words
In combination: a quick change drill chuck including a chuck portion and an adapter portion, said quick change drill chuck adapted for positioning ball elements within dimples circumferentially disposed about the central axis of said adapter portion of a tool; a fluid inducer system having an inducer body member and a fluid inducer connector extending in a radial direction with respect to said central axis of said adapter portion of a tool; said adapter portion of a tool having an oil hole coaxially disposed about said central axis of said adapter portion; said inducer body portion having a chamber coaxially disposed within said inducer body portion, said chamber coupled between said fluid inducer connector and said oil hole thereby permitting fluid flow therebetween; and, a tubular shaped nosepiece member circumferentially disposed about said central axis of said adapter portion of a tool, said tubular shaped nosepiece member including a slot thereby permitting extension of said fluid inducer connector therethrough.
Claim 2
Dependent Claim
159 words
In combination: a quick change drill chuck including a chuck portion and an adapter portion, said quick change drill chuck adapted for positioning ball elements within dimples circumferentially disposed about the central axis of said adapter portion of a tool; a fluid inducer system having an inducer body member and a fluid inducer connector extending in a radial direction with respect to said central axis of said adapter portion of a tool; said adapter portion of a tool having an oil hole coaxially disposed about said central axis of said adapter portion; said inducer body portion having a chamber coaxially disposed within said inducer body portion, said chamber coupled between said fluid inducer connector and said oil hole thereby permitting fluid flow therebetween; and, a tubular shaped nosepiece member circumferentially disposed about said central axis of said adapter portion of a tool, said tubular shaped nosepiece member including a slot thereby permitting extension of said fluid inducer connector therethrough.
Claim 3
Dependent Claim
64 words
The combination according to claim 1 further including a quick change drill bushing system having a quick change drill bushing member, said drill bushing member having an end portion inserted into a quick change drill bushing adapter member, said quick change drill bushing member and said quick change drill bushing adapter member coaxially disposed about the central axis of said tubular shaped nosepiece member.
