Visit to Vienna Technical Museum: pneumatic post

This photo is on the museum wall, but it appears elsewhere with the caption "Die pneumatische Post in Wien: Die Rohrpost-Abteilung in der k.k. Central-Telegraphenstation." It must be the original installation - see the Telegrams section for a later photo of a completely different arrangement.

Another information-board on the wall giving a brief outline of the system and the Crespin apparatus.

The apparatus-sketch from the original patent, contrast-enhanced.

This is part of a table that listed what facilities were available at which office.

Two Büchses

This isn't a nutcracker or an instrument of torture, but a device for removing bends and dents from the Büchse!
