Pressing into a pocket
Hop pressing was a strenuous job, especially before electric presses.
This shows a hop press (you can even see the name of the manufacturers - Drake and Fletcher who now have car dealerships). Suspended below the press and hanging down into the floor below is the hop pocket. The pocket is filled with the hops using the skuppet (what looks like a large tray with a handle at one end). When the pocket is filled the press would be wound down using the handle on the left of the press. This process would continue until the pocket was full.
