Abstract
Abstract A self-release and reload tooling device having a tool body, an adaptor nut for receiving a tool implement, a spring biased outer sleeve, and a spring biased release, whereby upon insertion of the adaptor nut in the tool body, the spring biased release is actuated freeing the outer sleeve which locks the adaptor nut to the tool body, and where upon manually sliding the outer sleeve back, the spring biased release is reset permitting removal of the adaptor nut, with the tool body then remaining in a position of readiness to receive and lock the next adaptor nut inserted in the tool body.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
295 words
A self-release and reload tooling device for removeably securing a tool implement to a tool body comprising: sleeve means located on the periphery of the tool body, said sleeve means moveable between a first and second position; bias means associated with the tool body to hold said sleeve means in the first position; adaptor meaNs operatively associated with the sleeve means such that said adaptor means is removeably insertable into the tool body when the sleeve means is in the second position, said adaptor means holding the tool implement; retainer means associated with the tool body to lock said sleeve means on the tool body in the first position, said retainer means being defined by a spherical retaining ring a portion of which is fixably associated on the periphery of the tool body, and the remaining portion intersecting with the sleeve means to lock said sleeve means in the first position; first locking means operatively associated with the sleeve means, the tool body, and the adaptor means, to lock the adaptor means to the tool body when the sleeve means is in the first position; second locking means associated with the tool body to lock said sleeve means on the tool body in both the first and second position; and release means operatively associated with said second locking means, for automatically releasing the sleeve means from the second position to the first position upon the insertion of said adaptor means into the tool body, said release means including a central body portion moveable between first and second release positions and release biasing means mounted within the tool body to biase the release means to said positions, said second locking means and release means defining a lock arrangement in both the first and second sleeve positions.
Claim 2
Dependent Claim
295 words
A self-release and reload tooling device for removeably securing a tool implement to a tool body comprising: sleeve means located on the periphery of the tool body, said sleeve means moveable between a first and second position; bias means associated with the tool body to hold said sleeve means in the first position; adaptor meaNs operatively associated with the sleeve means such that said adaptor means is removeably insertable into the tool body when the sleeve means is in the second position, said adaptor means holding the tool implement; retainer means associated with the tool body to lock said sleeve means on the tool body in the first position, said retainer means being defined by a spherical retaining ring a portion of which is fixably associated on the periphery of the tool body, and the remaining portion intersecting with the sleeve means to lock said sleeve means in the first position; first locking means operatively associated with the sleeve means, the tool body, and the adaptor means, to lock the adaptor means to the tool body when the sleeve means is in the first position; second locking means associated with the tool body to lock said sleeve means on the tool body in both the first and second position; and release means operatively associated with said second locking means, for automatically releasing the sleeve means from the second position to the first position upon the insertion of said adaptor means into the tool body, said release means including a central body portion moveable between first and second release positions and release biasing means mounted within the tool body to biase the release means to said positions, said second locking means and release means defining a lock arrangement in both the first and second sleeve positions.
Claim 3
Dependent Claim
63 words
The device as recited in claim 1 wherein the sleeve means includes an indenture located at the interface of said sleeve means and the periphery of the tool body, the indenture capable of receiving a portion of the first locking means and thereby permitting the unlocking of the adaptor means from the tool body when the sleeve means is in the second position.
Claim 4
Dependent Claim
23 words
The device as recited in claim 2 wherein the first locking means is a sphere and the second locking means is a sphere.
Claim 5
Dependent Claim
59 words
The self-release and reloading device as recited in claim 3 wherein the indenture of the sleeve means is capable of receiving a portion of the first locking means sphere when the sleeve means is in the second position and incapable of receiving any portion of the first locking means sphere when the sleeve means is in the first position.
Claim 6
Dependent Claim
62 words
The device as recited in claim 1 wherein the bias means to hold the sleeve means in the first position includes a spring biased to the first position, said spring seating on one side against a first shoulder on the periphery of the tool body and at the other end seating against a first shoulder on the interface of the sleeve means.
Claim 7
Dependent Claim
65 words
The device as recited in claim 2 wherein the sleeve means has a second interface shoulder which contacts a second shoulder on the tool body, to limit the sleeve means movement against the biasing means to a predetermined amount, the contacting of said second interface shoulder and the second shoulder on the tool body determining the point of the second position of the sleeve means.
Claim 8
Dependent Claim
129 words
The device as recited in claim 6 wherein the release means comprises: a central body moveable between a first release position and a second release position; a central cam surface located on the central body, communicating with the second locking means sphere when the central body is in the first and the second release positions; and a release biasing means removeably contained in the tool body to the second release position, when the sleeve means is in the second position; whereupon during movement of the sleeve means from the first position to the second position, the second locking means sphere moves along the central cam surface, said central cam surface forcing the second locking means sphere against the sleeve means to lock the sleeve means in its second position.
Claim 9
Dependent Claim
32 words
The device as recited in claim 7 wherein the release biasing means is a spring seated on one end against the tool body and on the other end against the release body.
Claim 10
Dependent Claim
66 words
The device as recited in claim 7 wherein the central cam surface comprises: a first cam surface located on the central body, communicating with the second locking means sphere when the sleeve means is in the first position; and a second cam surface located on the central body and communicating with the second locking means sphere when the sleeve means is moved to the second position.
Claim 11
Dependent Claim
81 words
The device as recited in claim 3 wherein the adaptor means comprises: a body section; a boss extending integrally from the body section; an adaptor groove around the periphery of the boss adapted to receive a portion of the first locking means sphere when the sleeve means is in the first position; and an adaptor opening extending axially along the body section, having an annular threaded surface which is adapted to receive and secure the tool implement to the body section.
Claim 12
Dependent Claim
40 words
The device as recited in claim 10 wherein the adaptor means further includes a set screw associated with the periphery of the body section and penetrating into the adaptor opening for non-rotatably fixing the tool implement to the body section.
