Abstract
Abstract A swing tube diverter construction for multiple station pneumatic tube systems. A pneumatic tube section is mounted at one end to swing between two positions extending from a tube system main line. A pair of rollers is mounted on the swinging tube section adjacent the swinging end thereof. A rotatable drive yoke connected to a reversible motor has a slot engaged with one of the rollers. The other roller is engaged in a fixed generally U-shaped cam track. The cam roller follows the path of the cam track in cooperation with movement imparted to the swinging tube section by the other roller engaging the yoke. This selectively connects the swinging tube section to one or the other of two branch tube system legs. Thus a carrier may travel in either direction between the main line and a selected branch leg.

Claim 1
Independent Claim
256 words
Swing tube diverter construction for a pneumatic tube system having a main tube and a pair of branch tubes including, swing tube means having first and second ends; means operatively connecting the swing tube means first end to the system main tube providing limited axial and angular movement of said swing tube means with respect to said main tube, said connection means being substantially airtight; first and second pin means mounted on the swing tube means; means resiliently mounting the second pin means on the swing tube means for limited axial movement therealong; drive means for moving the swing tube means between two positions each aligned with an end of one of the two branch tubes, and for selectively engaging and disengaging the swing tube means second end with an end of a selected branch tube; said drive means including a stationary cam plate spaced from and extending transversely across the swing tube means and formed with a Ushaped cam track; said cam track having a pair of spaced leg portions, each leg portion extending axially towards and aligned with one of the branch tubes; the first pin means being engaged with the cam track and movable therealong as the swing tube means moves between the branch tubes; yoke means spaced from the swing tube means and having spaced leg means forming a slot therebetween engaged with the second pin means; reversible motor means for rotating said yoke means; the motor means having a shaft; and the yoke means being mounted on said motor means shaft.
