Description
Hydraulic capsule 2 is subject to the force acting on bottom a of pressing chamber 3, and hydraulic capsule 1 is subject to the force of friction between the hay being pressed and the walls of pressing chamber 3. During the hay pressing operation, accomplished by ram 5 which is driven by connecting rods 6, the liquid in the hydraulic capsules is compressed, deforming Bourdon tubes 4 and 7, connected to the capsules. The movement of the free ends of the tubes is transmitted to pens f, recording the pressures on chart paper. Motion of the ram is transmitted by pin b to slider 8 which travels along guide column 9. At this, flexible link 10, running over pulley 11, moves the strip of chart paper 12.
