A Wedge Running in a Channel to Press an Object
The wedge a advances along a channel to compress the body b
The lower half of the sheet shows a wedge ('conio') mechanism set within a rectangular frame or box. The note explains that the wedge a must run along a channel, while b is the object pressed by the wedge as it advances. Above, a tall column-and-arm assembly and faint underlying sketches (not transcribed here) continue the run of machine studies.

The wedge a and the pressed body b
The caption explains the action of the wedge press: the wedge a must run along a channel, and b is the thing pressed by the wedge as it drives forward. The central diagram shows the tapering wedge entering a box against the body it compresses.
