notes: label: Description
content: This is a model of an early boiler riveting machine, which was donated to the museum by Charles H. Haswell, a consulting and topographical engineer and city surveyor from New York City.
label: Description
content: The machine consists of two aligned vertical cylinders supported on the upper overhang of a frame cast in the shape of a capital ‘G,’ the lower arm of which carries an anvil. This anvil serves as one member of the work clamp as well as the ‘backer-up’ for the hammer. The other member of the clamp is the piston of the lower cylinder. It is hollow and passes over the rivet to bear on the plates to be riveted, pressing them together against the anvil. The riveting hammer is the piston rod of the upper cylinder. It is solid and passes through the hollow piston and rod of the lower cylinder to strike the rivet.
label: Description
content: In operation the plates to be riveted, with the rivet inserted, are placed on the anvil, the head of the rivet resting on a pocket in the anvil. Steam is then admitted by a hand operated valve to the lower cylinder, forcing down its piston and hollow rod which surrounds the unfinished rivet and clamps the plates. By rocking the hand lever on the valve of the upper cylinder steam is admitted alternately to either side of the piston, causing the hammer rod to strike several blows to form the rivet head. The piston is halted in the upward position, and the lower piston is raised, releasing the finished work.
