The drawing shows a device for providing three dimensional motion such as required for access to storage bins.

Positioning along the X axis is accomplished by carriage I which moves in two directions on guide rails 2. Motion in the Y direction is provided by carriage 3 which is slidably mounted on guide rails 4. Since guide rails 4 are mounted on carriage 1, the position of carriage 3 is the result of motion by carriage I and carriage 3 in the X and Y directions, respectively. Motion along the third, or Z axis, is provided by means of carriage 5 which is slidably mounted on guide rail

The carriages are moved along their guides by selectively engaging moving belt 7 driven by motor 8 through a pair of clutches 9 and 10. The clutches permit reversal of the direction of belt motion to provide motion of the carriages in both directions.

With both clutches disengaged, the access mechanism is held stationary by means of detents and capstans. For example, carriage 1 is held by a mechanism, not shown, which engages detent bar 11 at the locations of holes
12. Carriage 3 is held stationary on guides 4 by means of cable 13 which makes several turns about capstan 14 and is secured at both ends. Devices are provided for locking capstan 14 to prevent motion of carriage 3 on guides 4. Similarly, when locked against rotation, capstan 15 holds carriage 5 in a stationary position on guide 6 since belt 7 makes several turns about capstan 15 and is also secured to carriage 5 at point 19.

The detents and capstans permit the access mechanism to be freed for movement in either direction along any of the three axes. Should the detent mechanism be disengaged from detent bar 11, subsequent motion of belt...
