Abstract: An automatic label dispensing apparatus for dispensing a label on an article to be marked is disclosed. The apparatus includes provisions for the mounting of a conventional label ejector mechanism adapted to eject in serial format adhesive-backed labels on articles as the same are positioned thereunder. A horizontal support member is provided for positioning the ejector mechanism in a selected radial position and includes a pivot arm attached thereto which supports the ejector mechanism in position for operation. A pneumatic system is provided for arming the ejector mechanism, and in time relation the arm carrying the mechanism is rotated to bring the ejector label carried by the ejector mechanism in contact with the article to be marked and then return the ejector mechanism to its initial position to recycle the same.

Abstract: A pneumatic tube conveyor dispatcher for converting a pneumatic tube free dispatch system into a pneumatic tube controlled dispatch system. The dispatcher comprises a housing having a rear portion which matingly engages an existing terminal of the free dispatch system such that a carrier storage chamber within the dispatcher housing communicates with the inlet opening of the delivery tube of the free dispatch system. The dispatcher housing includes a door permitting access to the carrier chamber to enable an operator to position a carrier therein. Sensing means associated with the housing chamber senses the presence of the carrier and, in response to a predetermined signal, is operative to actuate a drive mechanism which delivers the carrier through the terminal inlet opening into the pneumatic tube for deployment.

Sensing means associated with the housing chamber senses the presence of the carrier and, in response to a predetermined signal, is operative to actuate a drive mechanism which moves a slider plate from across the terminal inlet opening to communicate the carrier with the pneumatic tube whereby the differential pressure across the carrier results in a force which acts on the carrier to transfer the carrier into the tube.

Abstract: In a conveyor system for forwarding trays along a support, the trays are engaged by pusher mechanisms attached to an endless driven chain supported on a track adjacent to the tray's support. Each pusher mechanism has a pivotally mounted pusher member that is associated with a pivoted control member located forwardly of the pusher member and connected thereto by a horizontally sliding connecting member. The pusher member and the control member are normally urged to positions in which the pusher member is drivingly engageable with a tray and the control member is engageable with an object such as a preceding tray overtaken by the control member; such engagement resulting in movement of the pusher member to a non-driving position and enabling trays to be stopped and accumulated.
