## Abstract

The invention relates to a tool magazine for automatic tool-changing device, comprising a circular disc mounted for rotation about a pin and comprising on its periphery a series of housings designed to receive the tools whose axes are directed according to the radii of the disc. At least one secondary disc is rotatably mounted co-axially to the main disc on which secondary disc are hingedly mounted, about an axis perpendicular to a radius of the secondary disc, members for supporting the secondary housings designed to receive the tools, the said secondary housings being adapted to be selectively pivotally engaged in an opening provided in the wall of the main disc. The invention is used for storing tools.

## Claims

### Claim 1

A tool magazine for an automatic tool-changing device, comprising:
(a) a first substantially circular disc mounted for rotation about a magazine axis, said first disc having on the periphery thereof a plurality of first tool-receiving housings, the axes of said first housings being arranged substantially on radii of said first disc;
(b) a second substantially circular disc mounted for rotation about said magazine axis;
(c) a plurality of second tool-receiving housings pivotally mounted on said second disc, the axes of said second housings being arranged substantially on radii of said second disc, said second housings further being pivotable about respective axes substantially perpendicular to said second radii; and
(d) an opening on the periphery of said first disc wherein a first housing would normally be positioned for selectively receiving a second housing therein.

### Claim 2 (depends on 1)

A tool magazine as defined in claim 1 wherein said second disc is positioned above said first disc.

### Claim 3 (depends on 2)

A tool magazine as defined in claim 2 including a pin and wherein said discs are mounted coaxially on said pin, and a cross-piece separating said discs.

### Claim 4 (depends on 1)

A tool magazine as defined in claim 1 wherein the opening in said first disc is adapted to be rotated to a tool-changing station.

### Claim 5 (depends on 1)

A tool magazine as defined in claim 1 including a plurality of bent rods, each rod supporting a second housing, a substantially circular wall having an opening therein, said second housings resting on said wall and being adapted to selectively be lowered into said wall opening.

### Claim 6 (depends on 5)

A tool magazine as defined in claim 5 wherein said wall opening and the opening in said first disc are coextensive.

### Claim 7 (depends on 6)

A tool magazine as defined in claim 6 wherein said wall is formed on said first disc.

### Claim 8 (depends on 1)

A tool magazine as defined in claim 1 wherein said second disc is rotatable relative to said first disc.
