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. [Illustration: Fig. 3.] 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. [Illustration] 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. |
