Pneumatic mail station for the delivery, pneumatically decelerated reception and transit of pneumatic dispatch cases
First Claim
1. A pneumatic mail station for the transmission, reception and transit of pneumatic dispatch cases, comprising two tube sections for coupling with an incoming and an outgoing forwarding tube path, wall means providing mutually opposite limiting walls of the pneumatic mail station at which the respective tube sections are located, said wall means having an inward transfer opening means for pneumatic dispatch cases to be sent out and an outward transfer opening means for received pneumatic dispatch cases at the same limiting walls, carrier means disposed between the limiting walls and having a reception tube chamber (8, 23) for the reception of pneumatic dispatch cases which can be introduced into alignment with the tube section associated with the incoming forwarding tube path, said reception tube chamber (8, 23) having closure means effective at one end of the reception tube chamber for creating an air pillow which decelerates an incoming pneumatic dispatch case and an air conduit (10, 20) pneumatically connecting the tube section associated with the incoming forwarding tube path to the tube section associated with the outgoing forwarding tube path in the reception position of the reception tube chamber (8, 23), characterized in that the reception tube chamber (8, 23) has said closure means at the end thereof closer to the outgoing forwarding tube path, said carrier means having a second tube chamber (9, 22) which extends parallel to the reception tube chamber (8, 23) and is displaceable in common with it, said second tube chamber (9, 22) being in alignment with the two tube sections (3, 29;
- 6,
30) in one position and being in alignment with the inward transfer opening means in another position; and
in that the air conduit (10,
20) joins at one end with the reception tube chamber (8,
23) and can be displaced in common with said reception chamber (8,
23) and the second tube chamber (9,
22) in such manner that, given the position of the second tube chamber (9,
22) in alignment with the two tube sections, the communication of the air conduit (10,
20) at least with the tube section (3,
29) associated with the outgoing forwarding tube path is blocked but, in contrast thereto, is released at the position of the reception tube chamber (8,
23) in alignment with the two tube sections.

Abstract
In an exemplary embodiment, a reception tube chamber closed at one end and a transit tube chamber open at both ends can be displaced in common, whereby, in the reception position of the pneumatic mail station, the reception tube chamber closed at one end is located with its open end area in front of a tube section associated with a forwarding tube path entering the pneumatic mail station from below. The disclosure is especially favorable in pneumatic mail systems with relatively large or, respectively, heavy pneumatic dispatch cases which are to be received in the pneumatic mail station pneumatically decelerated.

21. A pneumatic mail station for the transmission and reception of pneumatic dispatch cases, comprising tube section means for coupling with incoming and outgoing forwarding tube paths, wall means having inward and outward transfer opening means for pneumatic dispatch cases to be send out and for received pneumatic dispatch cases, carrier means mounted by the wall means for movement between first and second positions, and having a reception tube chamber operable in the first position of the carrier means for the reception of pneumatic dispatch cases, said reception tube chamber having an open end disposed in alignment with the tube section means in the first position of the carrier means for the reception of a dispatch case arriving via the incoming forwarding tube path, said reception tube chamber having a closed end for creating an air pillow which decelerates an incoming pneumatic dispatch case and having an air conduit pneumatically connecting with the reception tube chamber between its open and closed ends, and means comprising said air conduit for accomodating air flow toward said reception tube chamber in the first position of said carrier means.
