Abstract

The positioning system consists of the housings A, B, C, and D. These, when the system is positioned, are guided in cylinder T in the direction of arrow W. Membrane M in each housing is connected to one of the rods 1', 2', 4', 8', and 8", each of which pushes the succeeding one of the series-connected housings in the direction of arrow W.

Adder for Positioning System

The positioning system consists of the housings A, B, C, and D. These, when the system is positioned, are guided in cylinder T in the direction of arrow
W. Membrane M in each housing is connected to one of the rods 1', 2', 4', 8', and 8", each of which pushes the succeeding one of the series-connected housings in the direction of arrow W.

The rods are moved by membranes M extendible in the direction of arrow W by air pressure which can be selectively forced into the respective air chambers through air nozzles N. The membrane is extended against spring tension until its surface touches a cam in the respective housing.

Membranes M are spaced to perform strokes of S1, S2, S4, S8/2, thus ensuring that all membrane extensions are added for moving rod 1' to its final position. The maximum stroke of a membrane is limited to S8/2 so that two air chambers d1 and d2 are necessary for obtaining the full stroke of housing D.
