Quest.--Would you advise link belts for high rate of speed?

Ans.--No; they give better results on slow running machinery.

Quest.--Have these belts any special advantage over flat leather
belting?

Ans.--Yes, decidedly. When belts are run half crossed, or what is termed
quarter turn, it is very hard to make flat belts lie perfectly even on
the pulleys. These link belts, however, cover the entire face of the
pulley (see illustration), and therefore are superior for that purpose.

Quest.--Why do they give better results when run slow?

Ans.--Partly because of their great weight over ordinary belting, also
their grip power is stronger when run slow. No belt is superior to them
for slow, hard working machinery.

Quest.--Are they more expensive than ordinary flat belting?

Ans.--Not when compared to the work they can accomplish.

Quest.--Can they be run in wet places, such as mines, etc.?

Ans.--Yes; by waterproofing the leather, no cement being used as in flat
belts. The links can be made positively waterproof. We have furnished
paper mills, tanneries and bleacheries, and other exposed places with
waterproof link belts, and all have been entirely satisfactory so far.

Quest.--Can they be run on ordinary flat pulleys?

Ans.--Yes; our "American joint" link belt can be run on any straight or
rounded pulley, whether made of iron, paper, or wood, and being all
endless they run much smoother than other belting.

Quest.--How are they made endless?

Ans.--By a very simple process (see illustration), and takes almost less
time than lacing a flat belt. All that is necessary is to take both ends
and interlock the links, then pass the bolt through and rivet it, and
when you wish to shorten the belt proceed likewise: File off the end of
the bolt and take out, or add rows of links at pleasure and rejoin it
again.

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.
