Bell Crank

The bell crank is used to convert the direction of reciprocating movement. By varying the angle of the crank piece it can be used to change the angle of movement from 1 degree to 180 degrees. The bell crank was originally used in large house to operate the servant’s bell, hence the name.

And make sure each grain of the sugar has been individually sculpted into a microscopic model of Donald Duck sun-bathing on a deck chair.
