Fig. 4 is a complete round link belt.

Quest.--What is the relative strength of a link belt compared to flat belting?

Ans.--Nothing definite has yet been ascertained. We are preparing a table showing results, and so far we can report that they can stand about twice the strain of double flat belts. A four inch link belt one inch thick is able to do the work of an eight inch flat double belt.

Quest.--Explain the advantage of your American joint over the English hinge.

Ans.--The American joint gives a perfect unbroken surface of entire width of belt, whereas the English hinge joint makes two half widths, and whenever a sudden change of power occurs and the belt runs half way off the pulley, it will catch at the edge and tear everything to pieces.
