Abstract
Abstract A shank and socket type of interfitting tool adapter and machine tool spindle having pins on the adapter and holes in the spindle to insure a particular angular orientation of the adapter relative to the spindle prior to interfitting of the parts and engagement of a multiple tooth type of driving clutch.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
234 words
In a machine tool having a driven spindle with a socket for receiving a tool-carrying adapter, the combination comprising, an annular drive plate on said spindle and surrounding said socket, a tool adapter formed to fit into said socket and having an annular flange which abuts said plate when the tool adapter is locked in said spindle socket, a plurality of annularly spaced clutch teeth on both said drive plate and said adapter, said clutch teeth being shaped to closely interfit and positively couple the adapter to said spindle when said flange and said plate abut, a plurality of pins fixed on said flange to extend axially thereof and disposed angularly about the axis of the flange so that the adapter can be nontiltingly supported on the ends of said pins, said drive plate having a plurality of holes formed axially therein to receive said pins in an angular position of said adapter relative to said spindle that permits said clutch teeth to interfit, said pins having chamfered ends to facilitate entry into said holes, said pins and said holes being asymmetrically arranged about said axes so that the pins and holes will meet in only one angular position of the adapter relative to the spindle, and said holes being sufficiently larger than said pins to prevent rotational drive from said spindle to said adapter through said pins when said clutch teeth are interfitted.
Claim 2
Dependent Claim
234 words
In a machine tool having a driven spindle with a socket for receiving a tool-carrying adapter, the combination comprising, an annular drive plate on said spindle and surrounding said socket, a tool adapter formed to fit into said socket and having an annular flange which abuts said plate when the tool adapter is locked in said spindle socket, a plurality of annularly spaced clutch teeth on both said drive plate and said adapter, said clutch teeth being shaped to closely interfit and positively couple the adapter to said spindle when said flange and said plate abut, a plurality of pins fixed on said flange to extend axially thereof and disposed angularly about the axis of the flange so that the adapter can be nontiltingly supported on the ends of said pins, said drive plate having a plurality of holes formed axially therein to receive said pins in an angular position of said adapter relative to said spindle that permits said clutch teeth to interfit, said pins having chamfered ends to facilitate entry into said holes, said pins and said holes being asymmetrically arranged about said axes so that the pins and holes will meet in only one angular position of the adapter relative to the spindle, and said holes being sufficiently larger than said pins to prevent rotational drive from said spindle to said adapter through said pins when said clutch teeth are interfitted.
Claim 3
Dependent Claim
31 words
The combination of claim 1 in which each pin and its corresponding one of said holes is spaced from said axes at a different distance from the other pins and holes.
Claim 4
Dependent Claim
22 words
The combination of claim 1 in which there are three of said pins and three of said holes, each spaced 120* apart.
Claim 5
Dependent Claim
127 words
In a machine tool having a driven spindle member with a socket for receiving a tool-carrying adapter member, the combination comprising, positive drive means coupling said members, and orienting means connecting said members so that the adapter member is receivable in said spindle socket in only one angular position, said drive means and said orienting means being engageable upon relative axial movement of said members, said orienting means including an element projecting from said spindle member and a recess formed in said adapter member for receiving said element, the fit of said element in said recess allowing limited degree of rotational freedom between said members so that said orienting means is effective to orient and said drive means is effective to drive independently of said orienting means.
Claim 6
Dependent Claim
127 words
In a machine tool having a driven spindle member with a socket for receiving a tool-carrying adapter member, the combination comprising, positive drive means coupling said members, and orienting means connecting said members so that the adapter member is receivable in said spindle socket in only one angular position, said drive means and said orienting means being engageable upon relative axial movement of said members, said orienting means including an element projecting from said spindle member and a recess formed in said adapter member for receiving said element, the fit of said element in said recess allowing limited degree of rotational freedom between said members so that said orienting means is effective to orient and said drive means is effective to drive independently of said orienting means.
