THE CANADA LUMBERMAN November, 1904 THE ^OT^oocL-lftTorvkier and Retailer BELT ADJUSTMENTS IN THE COOPER SHOP. Figure 1 represents the incorrect manner in which some belts are prepared for making the union with laces. I have noticed defective joints in belts in cooperage shops of this char- acter. The makers of the belting leather never calculated that the belts would be joined in any way except the straight, parallel align- ment. In the making of the belt leather, pre- cautions are taken to overcome stetching of one side of the belt more than the other, by cutting the belt properly from the hide. If the piece were cut from the hide so as to in- volve portions of the center, the sides, the head] and offals, then there would be about as manyl different degrees of stretching of the belt in] different parts, resulting in a wabbly affair that] would fail to give effective power. But the belt manufacturers reduce these differences in 1 stretching of the belting to a minimum by selecting the belt stock from such portions of the hide as will assure even stretching, uniform elasticity and evenness in general of the fibre. The belt is finished and sent to the users. In many of the power-consuming instiutions there are power engineers who oversee the work of the belting adjustments and correct imperfect set- ting. But in the average shop there are only the ordinary workman to care for the belts. A specialist is not employed nor would it be practicable to have one. Therefore in exam- ining the belts one finds various conditions arising in the cooperage shop for imperfect results and ruined belting. The illustration given in the first figure is to show how the belt butts are often united, resulting in drawing the belt line from its true course, and making the belt run from side to side on pulleys. The true line would be " b ", taking "a&
