Upon the main shaft g, is mounted a cylindrical hollow box or drum-pulley, whenceone cord passes to drive the whirls and spindles f and d, and another to drive thebobbins e.

Th'

a to c ybndrical box pulley is made in two parts, k and l, and slipped uponin „ ot " e d wheel m, intervening between them. The box and wheel are sh

343, and partly in section at Jig. 344. That portion of the box with its pulleyto ' ^ is fixed to the shaft g; but the other part of the box and its pulley k, and theco n g , w beel m, slide loosely round upon the shaft g, and when brought in contact anddi st - ““ by a fixed collar n, as in the machine shown at Jig. 342, they constitute twoIn it! * >u ^ e l' s > one being intended to actuate the spindles, and the other the bobbins,at ritrhi ' ve * > °f the wheel m, a small bevel pinion o, is mounted upon an axle standingp apg 1 a ngles to the shaft g, which pinion is intended to take into the two bevel pinionsand / respectively fixed upon bosses, embracing the shaft in the interior of the boxes kg, ari j Now it being remembered that the pinion q, and its box l, are fixed to the shaftdifferent 1111 ’I the loose wheel m be independently turned upon the shaft, with a
