Lecture I. | Rivets and Rivetted Joints: single and double rivetting; lap and butt joints; joints where three or four plates lap; angle and T iron joints; gussets; various connections for boilers and tanks. |
II. | Bolts, Nuts, and Set Screws: their proportion, and arrangement of flanging for bolting; eye, T, and hook bolts; lock nuts; stays for boilers; strength of bolts (testing machines). |
III. | Shafts, Couplings, and Pulleys: wrought and cast iron flange couplings, butt and lap; belt pulleys; pulleys for cranes; speed cones and countershafts. (Weston's differential pulley block); to find the power transmitted by shafting, friction brake; friction and torsion of shafting. |
IV. | Pedestals, Plummer Blocks: wall plates and boxes; hanging brackets. |
V. | Gearing: spur and bevel gearing, frictional gearing, antifrictional wheels; rack and pinion; worm and worm wheel; relation of pitch, number of teeth, and diameter of pitch circle; velocity ratio of a pair of wheels; skew bevel wheels; mortise wheels; carrier and change wheels. |
VII. | Cranks, Eccentrics: conversion of rotary motion, into an alternating uniform, or varying rectilinear motion; periods of rest at given points of the revolution, as applied to punching machines, &c.; Whitworth's quick-return motion for shaping machines. |
