Abstract
The river setter is operated hydropneumatically and comprises fixed and mobile arms. The latter is attached to a spring-loaded piston ram (7), its rear chamber (8) filled with hydraulic fluid. Pressing a trigger (24) admits compressed air (14) behind (11) a piston (12), its movement expelling the hydraulic fluid (10) for the mobile arm approach stroke. Further trigger pressure (25) admits the air behind (17) a separate large diameter spring loaded piston (18). This has a small plunger (19) which acts directly on the hydraulic fluid (9) behind the mobile arm piston and intensifies the hydraulic pressure to set the rivet.
