THE PULLEYS AND BELTING OF A SEPARATOR 215 



rubber or stitched canvas belt that does not run over idler 

 or tightener pulleys, causing both sides of the belt to be 

 in contact with pulleys, may be laced in this way. For 

 these this lacing has the advantage of lasting two or three 

 times as long as the ordinary one. The reason is that the 

 lace is not exposed to wear and the belt will pass around

the smallest pulley without straining either holes or lace 

 leather. If trouble be experienced in keeping an old main 

 belt laced, this method may be used with success. 



A four-inch belt laced in the ordinary manner is shown 

 by Fig. 53. The side shown in the first view should be run 

 next to the pulley. The lacing shown in Fig. 55 

 is very satisfactory where a belt passes over small pulleys 

 or idlers, for it bends easily in either direction. It is there- 

 fore very durable and satisfactory for a rubber or stitched 

 canvas wind stacker belt. Also the belt driving beater and 

 crank should be laced this way, but as this is of leather, the 

 holes may be nearer the end than in the cut, which shows 

 the spacing for rubber or stitched canvas.
