Of thè Axle- Bed. 239 cular from the centre of the outer buſh. ft is plain that K L is egual to half the taper, or difference between the width of the buſhes. FI is alſo plain, that I L is to LK as LQto QP, which is half the gather of that wheel. Again, let EFEG(fg. 8.) be âñother axle,

ftraiglit below, with only one inch of

taper. MO wut, in like manner, be

half the taper, and half.of KL. SE will therefore be half of PQ. Tf, now, we make 8 T equalto PQ, we muſt bend the arm to the poſition H ŸV with its lower ſide, ſo that G V may be equat to MO. This will bring down the centre O as much further as it is already below the level M N, and then the po- ſition ot the face O T will be’ the ſame with that of the face LP, and, confſe-
