Abstract

A system for transferring pneumatic carriers from one pneumatic carrier receiving/dispatching station to another includes a first pneumatic carrier diverter, or a plurality of such first diverters, each with an inlet/outlet linked through pneumatically-sealed tubes to at least one such station, a multiplicity of outlets, and a device for shiftably linking the inlet/outlet of the diverter to any one of its multiple outlets; a second pneumatic carrier diverter, or a plurality of such second diverters, each with a multiplicity of inlets and a single outlet, and a mechanism for shiftably linking the multiplicity of inlets to the outlets; the system including either a plurality of such first diverters, or a plurality of such second diverters, or both; pneumatically-sealed tubes joining, in parallel, all the diverters of the first kind of all the diverters of the second kind; and a pressure/vacuum supply device joined to the outlet of one or more of the second kind.

Claims

1. A system for transferring pneumatic carriers from one pneumatic carrier receiving/dispatching station to another comprising a first group of pneumatic carrier diverters, each with an inlet linked through pneumatically-sealed tubes to at least one of said stations, a multiplicity of outlet means, and means for shiftably linking said inlet means to any one of said outlet means;

a second group of said diverters, each with a multiplicity of inlet means and an outlet means, and means for shiftably linking said multiplicity of inlet means to said outlet means, said transferring system including a plurality of diverters of said first group and a plurality of diverters of said second group with at least three diverters and at least one of said first and said second groups of diverters;

pneumatically-sealed tubes joining in parallel, all the diverters of said first group to all the diverters of said second group; and

at least one means for supplying pressure and vacuum to said system, joined to the outlet means of a diverter of said second group.

2. The system of claim 1 wherein the outlet means of at least two diverters of said second group is joined to separate pressure/vacuum supply means.

3. The system of claim 2 further comprising means for operating each of said pressure/vacuum supply means simultaneously and independently of one another.

4. The system of claim 3 wherein said system permits directing a pneumatic carrier entering the system to the outlet means of any selected diverter of said second group, and for then directing said pneumatic carrier to and through any selected diverter of said first group.

5. The system of claim 4 wherein at least two diverters of said first group each has a single inlet means joined, through pneumatically-sealed tubes, to a separate group of stations.

6. The system of claim 3 wherein at least two diverters of said first group each has a single inlet means joined, through pneumatically-sealed tubes, to a separate group of stations.

7. The system of claim 2 wherein at least two diverters of said first group each has a single inlet means joined, through pneumatically-sealed tubes, to a separate group of stations.

8. The system of claim 1 wherein the outlet means of each diverter of said second group is joined to separate pressure/vacuum supply means.

9. The system of claim 8 further comprising means for operating each of said pressure/vacuum supply means simultaneously and independently of one another.

10. The system of claim 9 wherein said system permits directing a pneumatic carrier entering the system to the outlet means of any selected diverter of said second group, and for then directing said pneumatic carrier to, and through any selected diverter of said first group.

11. The system of claim 1 wherein at least two diverters of said first group each has a single inlet means joined, through pneumatically-sealed tubes, to a separate group of stations.

12. A pneumatic tube system including:

(a) A system for transferring pneumatic carriers from one pneumatic carrier receiving/dispatching station to another comprising a first group of pneumatic carrier diverters, each with an inlet linked through pneumatically-sealed tubes to at least one of said stations, a multiplicity of outlet means, and means for shiftably linking said inlet means to any one of said outlet means;

a second group of said diverters, each with a multiplicity of inlet means and an outlet means, and means for shiftably linking said multiplicity of inlet means to said outlet means, said transferring system including a plurality of diverters of said first group, and a plurality of diverters of said second group with at least three diverters and at least one of said first and said second groups of diverters;

pneumatically-sealed tubes joining, in parallel, all the diverters of said first group to all the diverters of said second group; and

at least one means for supplying pressure and vacuum to said system, joined to the outlet means of a diverter of said second group; and

(b) At least two separate groups of stations, each station group including a single inlet/outlet pneumatic tube joined to the inlet means of one, and only one diverter of said first group of diverters, wherein said pneumatic tube system permits transferring a pneumatic carrier from one station group to another station group with no more than one shift in each diverter through which said pneumatic carrier passes.

13. The system of claim 12 wherein said system permits transferring a pneumatic carrier from one station in a group to another station within the same group with no more than one shift in each diverter through which said pneumatic carrier passes, and with said pneumatic carrier passing through no more than two diverters.

14. The system of claim 13 wherein at least one group of stations includes at least two subgroups of at least two stations each, with each subgroup including at least one station diverter having a plurality of inlets linked, through pneumatically-sealed tubes, to the inlet/outlet of at least two stations within said subgroup, and having outlet means linked, through pneumatically-sealed tubes, to inlet means of a subgroup diverter, said system including means for transferring a pneumatic carrier from any station in one subgroup to any station in any other subgroup within the same group without leaving said group during the transfer.

15. A pneumatic tube system including:

(a) A system for transferring pneumatic carriers from one pneumatic carrier receiving/dispatching station to another comprising a first group of pneumatic carrier diverters, each with an inlet linked through pneumatically-sealed tubes to at least one of said stations, a multiplicity of outlet means, and means for shiftably linking said inlet means to any one of said outlet means;

a second group of said diverters, each with a multiplicity of inlet means and an outlet means, and means for shiftably linking said multiplicity of inlet means to said outlet means, said transferring system including a plurality of diverters of said first group, and a plurality of diverters of said second group with at least three diverters and at least one of said first and said second groups of diverters;

pneumatically-sealed tubes joining, in parallel, all the diverters of said first group to all the diverters of said second group; and

at least one means for supplying pressure and vacuum to said system, joined to the outlet means of a diverter of said second group; and

(b) At least two separate groups of station, each station group including a single inlet/outlet pneumatic tube joined to the inlet means of one, and only one diverter of said first group, said pneumatic tube system including means for linking any one of said pressure/vacuum supplying means to said pneumatic tube system for transferring a pneumatic carrier from one group of stations to another group of such stations.

16. The system of claim 15 wherein said system permits transferring a pneumatic carrier from one station in a group to another station within the same group with no more than one shift in each diverter through which said pneumatic carrier passes, and with said pneumatic carrier passing through no more than two diverters.

17. A pneumatic tube system including:

(a) A system for transferring pneumatic carriers from one pneumatic carrier receiving/dispatching station to another comprising a first group of pneumatic carrier diverters, each with an inlet linked through pneumatically-sealed tubes to at least one of said stations, a multiplicity of outlet means, and means for shiftably linking said inlet means to any one of said outlet means;
