BELT DRESSINGS 65 



months. If, however, the belt should slip during working 

 hours as a result of neglect or of being subjected to a heavier 

 load than that for which it was intended, a dressing should 

 be applied sparingly to enable it to continue to pull its load 

 until the machine can be shut down and the belt tightened. 



The Tabor Manufacturing Company, Philadelphia, in 

 the instructions issued with the belt benches described in 

 Chapter V, recommends the cleaning of belts at intervals of 

 six months and the application of a grease that will give to 

 the surface a clean sticky pulling surface, similar to that 

 which it has when new due to the oils and grease that it 

 contains. The grease in the new belt becomes exhausted 

 after the belt has been in service for a certain length of time, 

 as the result of heat, friction and atmospheric action, and the 

 application of additional grease is necessary if the belt is 

 to be maintained in a soft and pliable condition. The grease 

 recommended is the same as that put in the new belt by the 

 manufacturers and consists of 



Edible beef tallow 2 Ib. 



Cod liver oil i Ib. 



The tallow is melted and allowed to cool slightly, after which 

 the cod liver oil is added and the mixture stirred in one direc- 

 tion until cold. This grease can be purchased mixed ready 

 for use from Alexander Bros., Philadelphia. It should be 

 applied in light coats by means of a camel's hair brush, 

 and only in such quantities as the belt will easily absorb. 



For use on belts which slip in service the same company 

 recommends the " Plomo " dressing, made by the Plomo 

 Specialty Co., Cleveland. A few drops of this applied 

 to the belt will enable it to pull its load for several hours, 

 until the opportunity presents itself for tightening the belt. 

 The dressing, however, should not be regarded as a preserva- 

 tive, and its use should be limited to the purpose described 

 above. It should be used sparingly, as a too liberal applica-
