Abstract
Abstract A tool magazine for machine tools provided with program control and automatic tool changing. Tool-receiving seats are disposed in a helical line in equally angularly spaced axially extending rows along a cylinder which is simultaneously rotated and axially traversed so as sequentially to present desired tools at a fixed tool pick up point or station. The magazine has a motor which drives the cylinder, the motor being under the control of a pulse counter actuated by cams which are spaced at the same angle as the successive rows of seats in the cylinder.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
83 words
A tool magazine comprising a frame, a cylinder having a plurality of tool-receiving seats arranged in a helical line on the cylinder and arranged in a plurality of equally angularly spaced axially extending rows, a fixed tool pickup station disposed to pick up a selected tool from its seat in the cylinder, and means to rotate the cylinder and to move it axially so as to move the tool seats so that each tool seat is sequentially positioned at the tool pickup station.
Claim 2
Dependent Claim
83 words
A tool magazine comprising a frame, a cylinder having a plurality of tool-receiving seats arranged in a helical line on the cylinder and arranged in a plurality of equally angularly spaced axially extending rows, a fixed tool pickup station disposed to pick up a selected tool from its seat in the cylinder, and means to rotate the cylinder and to move it axially so as to move the tool seats so that each tool seat is sequentially positioned at the tool pickup station.
Claim 3
Dependent Claim
45 words
A tool magazine according to claim 1, comprizing a fixed column on which the cylinder is rotatably supported for movement axially thereof, and cooperating helical cam and cam follower means on the cylinder and column for causing the cylinder to travel axially as it rotates.
Claim 4
Dependent Claim
56 words
A tool magazine according to claim 2, wherein the cylinder is journalled on the column, the helical cam is a helical groove in the outer surface of the column, and the cam follower is composed of at least one radially inwardly directed member affixed to the cylinder and having its inner end received in the groove.
Claim 5
Dependent Claim
46 words
A tool magazine according to claim 3, wherein the means for rotating the cylinder comprises coaxial first and second shafts drivingly connected for axial travel relative to each other, a motor for rotating the first shaft, and means drivingly connecting the second shaft to the cylinder.
Claim 6
Dependent Claim
24 words
