Cleaning and Greasing. At periodical intervals, say 

 six to eight months, the belt-fixer should, in addition to 

 weighing the tension, clean and grease the belt with an 

 approved dressing. A good dressing is as follows: 



A. Boiled linseed oil 37 per cent by measure. Tallow, 



30 per cent by measure. 



B. Machine oil, 27 per cent by measure. Beeswax, 



6 per cent by measure. 



A and B are heated separately to 360 deg. and mixed 

 while hot. Additional information regarding belt dressings, 

 cleaning and greasing is given in Chapter VII. 



Time at which Belt Work Should be Done. Belts should 

 be tightened and repaired outside of working hours, unless 

 there is a belt break-down or a machine is standing idle with 

 no prospect of being used during the time that the belt 

 will be under repair. It is 'recommended that the belt-fixer 

 be given six belts to tighten each day; three being done 

 during the noon hour and three after quitting time in the 

 afternoon. The belt orders should, therefore, be divided into 

 lots of six, each lot being dated for the date on which the 

 belt is to be tightened, and the lots filed accordingly in the 

 tickler file. If the number of belts is such that by dividing 

 the belts into lots of six, a greater period than two months 

 will elapse before all the belts in the shop are inspected and 

 tightened, it will be necessary to increase the number tightened 

 in any one day and provide assistance- for the belt-fixer, if 

 necessary. This system provides for considerable flexibility, 

 and good judgment on the part of the one in charge may be 

 exercised to advantage. As the conditions vary under which 

 different belts of the same size work, it is not always possible 

 to lay down fixed rules as outlined above, and the engineer 

 in charge of the work should then use his judgment in regard 

 to shortening the periods during which certain belts are run,
