Abstract
Abstract In a pneumatic tube dispatch system comprising a plurality of receiving and transmitting stations disposed along a main pneumatic line, an apparatus connected through one tube to said line is provided at each station with a substantially vertical movable tube section pivoted at its lower end and adapted to be set in two stable positions, namely a waiting and loading position in which it is adapted to receive a carrier for the message or other object to be transported along said line and an operative position in which it is connected to said one tube, electromagnetic means being provided for controlling the movement of said movable tube section from said waiting position to said operative position, as well as a rotary switch for selecting the address to which the carrier is to be delivered, a lighted pushbutton for registering this selection and a pilot lamp for warning the operator that the line is free. The movable tube section may be curved in case of larger tube diameters, and adapted to be loaded either laterally or from the top through an opening formed in the cabinet containing the apparatus and adapted to be closed in the operative position thereof by an element carried by said movable tube section.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
196 words
In a pneumatic dispatch system having a network of pneumatic tubes, an apparatus for receiving a carrier in a loading and waiting position and automatically introducing said carrier to said system at an appropriate time comprising a cabinet having a top wall with an opening therein capable of receiving a carrier therethrough and an open end of a fixed tube of said system extending therethrough, an open end tube section pivotally mounted in said cabinet in a position for having said tube section open end in one position coincide with said cabinet top wall opening and in a second position coincide with said fixed tube open end for the dispatch of said carrier, a member connected to and extending laterally of said tube section open end and capable of closing said cabinet top wall opening when said tube section open end coincides with said fixed tube open end whereby a carrier cannot be introduced through said cabinet top wall opening at that time, said tube section being curved along its axis, and electrically operable means connected to said tube section and capable of pivoting said tube section to said carrier dispatch position at the appropriate time.
Claim 2
Dependent Claim
196 words
In a pneumatic dispatch system having a network of pneumatic tubes, an apparatus for receiving a carrier in a loading and waiting position and automatically introducing said carrier to said system at an appropriate time comprising a cabinet having a top wall with an opening therein capable of receiving a carrier therethrough and an open end of a fixed tube of said system extending therethrough, an open end tube section pivotally mounted in said cabinet in a position for having said tube section open end in one position coincide with said cabinet top wall opening and in a second position coincide with said fixed tube open end for the dispatch of said carrier, a member connected to and extending laterally of said tube section open end and capable of closing said cabinet top wall opening when said tube section open end coincides with said fixed tube open end whereby a carrier cannot be introduced through said cabinet top wall opening at that time, said tube section being curved along its axis, and electrically operable means connected to said tube section and capable of pivoting said tube section to said carrier dispatch position at the appropriate time.
Claim 3
Dependent Claim
217 words
In a pneumatic dispatch system having a network of pneumatic tubes, an apparatus for receiving a carrier in a loading and waiting position and automatically introducing said carrier to said system at an appropriate time comprising an open end tube section pivotally mounted at its other end for pivoting to and from an open end of a fixed tube of said system whereby at times said tube section open end coincides with said fixed tube open end for the dispatch of said carrier into said fixed tube and at other times said tube section is pivoted from said fixed tube open end to the loading and waiting position, a pin connected to and extending perpendicular to the axis of said tube section other end providing the pivotal support for said tube section, means supporting said pin and electrically operable means connected to said tube section and capable of pivoting said tube section to said carrier dispatch position at the appropriate time, said electrically operable means includes an electro magnet operated plunger, a pulley carried by said plunger, and a belt fixed at one end, extending over said pulley and connected at its other end to said tube section other end whereby activation of said electro-magnet pivOts said tube section to coincide with said fixed tube open end.
