Abstract
Abstract A tool adapter, which has a tool connected thereto, is retained within a spindle with the tool adapter and the spindle having cooperating tapered surfaces to produce a tight fit therebetween. First means moves the tool adapter to break the connection between the tool adapter and the spindle while second means, which moves in the opposite direction to the first means, renders the means, which retains the tool adapter within the spindle, ineffective after the tool adapter has been grasped by a tool transfer arm.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
128 words
In a machine tool having a spindle, a tool adapter for supporting a tool, the spindle and the tool adapter having cooperating surfaces to form a tight fit therebetween and to support the tool adapter within the spindle, and means to retain the tool adapter in the spindle, the improvement comprising: first means movable to break the connection between the cooperating surfaces of the tool adapter and the spindle while the retaining means remains effective; and second means, separate from said first means, movable to render the retaining means ineffective only after said first means has broken the connection between the tool adapter and the spindle and said first means has ceased to move, said second means being stationary during movement of said first means and vice versa.
Claim 2
Dependent Claim
128 words
In a machine tool having a spindle, a tool adapter for supporting a tool, the spindle and the tool adapter having cooperating surfaces to form a tight fit therebetween and to support the tool adapter within the spindle, and means to retain the tool adapter in the spindle, the improvement comprising: first means movable to break the connection between the cooperating surfaces of the tool adapter and the spindle while the retaining means remains effective; and second means, separate from said first means, movable to render the retaining means ineffective only after said first means has broken the connection between the tool adapter and the spindle and said first means has ceased to move, said second means being stationary during movement of said first means and vice versa.
Claim 3
Dependent Claim
20 words
The improvement according to claim 1 in which said first means and said second means are movable in opposite directions.
Claim 4
Dependent Claim
22 words
The improvement according to claim 2 in which said first means moves in the direction in which the tool adapter is moved.
Claim 5
Dependent Claim
112 words
The improvement according to claim 1 in which: said first means includes: a movable piston; and means responsive to movement of said movable piston and acting on the tool adapter to break the connection between the cooperating surfaces of the tool adapter and the spindle; and said second means includes: a movable piston movable in directions parallel to the axis of the spindle; and means responsive to movement of said movable piston of said second means to render said retaining means ineffective, said movable piston of said second means remaining in the position to which it moved to render said retaining means ineffective until another tool adapter is disposed in the spindle.
Claim 6
Dependent Claim
50 words
The improvement according to claim 4 in which said movable piston of said first means is movable in the opposite direction to said movable piston of said second means, said movable piston of said first means being stationary when said movable piston of said second means moves and vice versa.
Claim 7
Dependent Claim
34 words
The improvement according to claim 5 in which said movable piston of said first means moves in the same direction as the tool adapter is moved to remove the tool adapter from the spindle.
Claim 8
Dependent Claim
69 words
The improvement according to claim 4 in which said first means includes means movable in the opposite direction to that in which said movable piston of said first means moves when the tool adapter is removed from the spindle, said movable means causing movement of said responsive means of said first means to clamp the tool adapter in the spindle when the tool adapter is disposed within the spindle.
Claim 9
Dependent Claim
32 words
The improvement according to claim 7 in which said movable means of said first means is not effective until after said movable piston of said second means renders said retaining means effective.
Claim 10
Dependent Claim
13 words
The improvement according to claim 1 in which the cooperating surfaces are tapered.
Claim 11
Dependent Claim
97 words
The improvement according to claim 1 in which: the retaining means includes: means engaging the tool adapter; and means cooperating with said engaging means to retain said engaging means in a position to retain the tool adapter in the spindle; means to hold said cooperating means of the retaining means stationary during breaking of the connection of the tool adapter and the spindle by said first means; and said second means includes means to move said cooperatinG means of the retaining means relative to said engaging means of the retaining means to render the retaining means ineffective.
