BELT POWER TRANSMISSION, XCVII. 
Mr. Hovcuton stated that he had used many belts of leather 
and also woven belts, and after running under practically similar 
conditions, had not noticed any great difference in wear between 
the two of them, no doubt a great deal depended upon the way 
the belts were kept. He pointed out the desirability of always 
keeping the bottom instead of the top of the belt tight, especially 
in link belts. 
Mr. Ross said in reply, that as regards Mr. Howe’s experience 
of rope driving as against leather in the United States, no doubt 
a tight belt is bad at all times. No belt should be tight. If the. 
belt is too tight then it must be either be driven at a speed which 
is too high or has passed the limit to which a leather belt can be 
used. Of course in such a case rope driving would no doubt be 
preferable, because it would depend for its transmission on the- 
friction of the rope lying in the groove.
