Abstract
Abstract A universal floating tool holder adapted for floatingly holding tools and particularly adapted for holding a tap for a tapping tool. The toolholder embodies telescoping bodies with a clutch in between the two bodies. Also between the telescoping bodies there are provided resilient means preferably in the form of O-rings. Provision is made for a limited amount of relative axial movement or displacement between the two bodies sufficient for clutch disengagemeent. The resilient means between the two bodies allows for relative radial or lateral float or displacement of one body relative to the other. The outer telescoping body holds the tool which may be attached in a chuck.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
182 words
A tool holder adapted to being carried by a machine and to hold a tool, comprising in combination a first body having means for attachment to a machine; a second body carrying a tool chuck, the first body and the second body being axially aligned and having parts in telescoping relationship; means for transmitting rotary drive from the first body to the second body; means interposed between the telescoping parts, providing for relative axial movement between the bodies and for limited lateral float of the second body relative to the first body where said interposed means between the telescoping parts includes resilient members having compressibility to allow for lateral float and where said interposed means comprises O-ring means positioned between the first body and the second body, whereby to allow the second body to float radially relative to the first body a limited amount; and a bushing surrounding the first body having an annular groove, said second body having a juxtaposed annular groove, said O-ring means being held in said grooves and said bushing being axially movable relative to the first body.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
32 words
A device as in claim 1 including a second bushing surrounding said first body, spring means interposed between the bushings and resilient means positioned to allow said second bushing to float radially.
Claim 4
Dependent Claim
