CRANK-PIN.
The Crank-Pin connects the connecting rod and crank. It is made of steel, and special care should be taken to keep the crank-pin well oiled. If allowed to run dry and cut, it will soon heat and ruin both pin and boxes. If once allowed to become cut, it will be impossible to prevent it from heating.
LINK REVERSE.
The Link Reverse is composed of two eccentrics and rods, link, block and slide, also lever and quadrant for holding link in any position. The duty of the link is to reverse the engine by simply throwing the reverse lever backward and forward. The speed of the engine can also be reduced and increased by the same operation.
