Abstract
Abstract A sealing collet is provided having a plurality of independent gripping jaws longitudinally disposed about a common centerline axis. The gripping jaws have exposed inner and outer faces. A resilient material is disposed between the gripping jaws and holds the jaws in a predetermined longitudinally and angularly spaced relation about the centerline axis of a collet. A continuous outer diameter seal is disposed circumferentially about the conical outer surface of the collet. The outer diameter seal is formed integral with the resilient material. A continuous inner diameter seal is also provided disposed circumferentially within the inner diameter of the collet and also formed integral with the resilient material. At least one coolant fluid channel may be defined in the resilient material in fluid communication with a coolant port defined through the face of the collet for introducing cooling fluid onto the working surfaces of a tool held by the collet.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
290 words
A sealing collet for use with tools having through holes defined therein for the induction of coolant fluid to the working surfaces of the tool, said collet comprising: a front face and a back face; a plurality of independent gripping jaws longitudinally disposed about a common centerline axis between said front face and said back face, said gripping jaws having an inner gripping face parallel to the centerline axis and defining an inner diameter for said collet through which the shaft of a machine tool can be inserted, said gripping jaws having an outer face whereby said plurality of gripping jaws forms an outer surface of said collet; resilient material disposed between each said gripping jaw, said resilient material holding said gripping jaws in a predetermined longitudinally and angularly spaced relation about the centerline axis; a continuous outer diameter seal disposed circumferentially about said outer surface, said outer diameter seal formed integral with said resilient material and extending circumferentially radially outward beyond said outer faces of said gripping jaws; a continuous inner diameter seal disposed circumferentially within said inner diameter, said inner diameter seal formed integral with said resilient material and extending circumferentially radially inward from said inner faces of said gripping jaws; at least one longitudinal channel defined within said collet between at least two of said gripping laws, said channel extending from said back face to said continuous inner diameter seal for carrying coolant fluid through said collet up to said inner diameter seal; and at least one coolant port defined through said front face of said collet in fluid communication with said longitudinal channel, said coolant port defining a path for coolant from within said collet to the working surfaces of a tool carried by said collet.
Claim 2
Dependent Claim
290 words
A sealing collet for use with tools having through holes defined therein for the induction of coolant fluid to the working surfaces of the tool, said collet comprising: a front face and a back face; a plurality of independent gripping jaws longitudinally disposed about a common centerline axis between said front face and said back face, said gripping jaws having an inner gripping face parallel to the centerline axis and defining an inner diameter for said collet through which the shaft of a machine tool can be inserted, said gripping jaws having an outer face whereby said plurality of gripping jaws forms an outer surface of said collet; resilient material disposed between each said gripping jaw, said resilient material holding said gripping jaws in a predetermined longitudinally and angularly spaced relation about the centerline axis; a continuous outer diameter seal disposed circumferentially about said outer surface, said outer diameter seal formed integral with said resilient material and extending circumferentially radially outward beyond said outer faces of said gripping jaws; a continuous inner diameter seal disposed circumferentially within said inner diameter, said inner diameter seal formed integral with said resilient material and extending circumferentially radially inward from said inner faces of said gripping jaws; at least one longitudinal channel defined within said collet between at least two of said gripping laws, said channel extending from said back face to said continuous inner diameter seal for carrying coolant fluid through said collet up to said inner diameter seal; and at least one coolant port defined through said front face of said collet in fluid communication with said longitudinal channel, said coolant port defining a path for coolant from within said collet to the working surfaces of a tool carried by said collet.
Claim 3
Dependent Claim
22 words
The collet as in claim 1, wherein said longitudinal channel is defined through said resilient material between two adjacent said gripping jaws.
Claim 4
Dependent Claim
19 words
The collet as in claim 2, further comprising a plurality of said longitudinal channels defined between said gripping jaws.
Claim 5
Dependent Claim
26 words
The collet as in claim 1, wherein said coolant port is defined through said front face at a point radially outward of said inner diameter seal.
Claim 6
Dependent Claim
13 words
The collet as in claim 4, comprising a plurality of said coolant ports.
Claim 7
Dependent Claim
19 words
The collet as in claim 1, further comprising a nozzle configured at the front end of said coolant port.
Claim 8
Dependent Claim
29 words
The collet as in claim 6, wherein said nozzle is positionable relative said coolant port so that coolant can be directed at any given angle from said front face.
Claim 9
Dependent Claim
20 words
The collet as in claim 1, wherein said coolant port is defined through said resilient material between said gripping jaws.
Claim 10
Dependent Claim
18 words
The collet as in claim 8, wherein said coolant port comprises a tube extending through said resilient material.
Claim 11
Dependent Claim
55 words
The collet as in claim 1, comprising three said coolant ports disposed equidistantly around said centerline axis of said collet, each said port further comprising a pivotable nozzle disposed in the end thereof, said nozzle being variably positionable to direct coolant fluid from said port at varying angles onto a tool extending from said collet.
