Abstract
The present application discloses braking devices for use in a pneumatic tube system (PTS). The braking devices are adapted for in-line incorporation with a pneumatic tube and are operative to stop a pneumatic carrier within a pneumatic carrier system. The in-line braking devices allow for decelerating a carrier to a stop over a distance to reduce the forces applied to a carrier and its contents.
Claims18
1-5. (canceled)
A brake device for use in a pneumatic tube carrier system, comprising:
- a pneumatic tube having an internal bore extending between an inlet end and an outlet end, wherein said internal bore is sized to accommodate the passage of a pneumatic carrier through said internal bore, wherein said pneumatic tube further includes an axial slot extending along a portion of a sidewall between said inlet end and said outlet end;
- and
- a contact element having a portion extending through said axial slot into said internal bore for contact with the pneumatic carrier passing through said internal bore.
The device of claim 16, further comprising:
- a first valve and a second valve configured to controllably open and close first and second ports in a sidewall of said pneumatic tube between said inlet end and said outlet end, respectively.
The device of claim 16, further comprising:
- first and second spring loaded stops, each selectively disposable into said internal bore of said pneumatic tube.
