As the vis inertia?prevents the instant communication of asufficient velocity to the basket loaded withheavy goods, various expedients have beenresorted to to make communicated velocityprogressive. The contrivances for this pur-pose, on the original English patent, are ex-tremely complicated; but the arrangementshown in Fig. 2277, (which is an exteriorview of the machine and the driving appa-ratus,) is much more simple, and perfectlyeffective. It is the invention of M. C. Bry-ant, of Lowell, Massachusetts. The wholemachine rests on two square bed-stones;the outside of the case, or tub, is only shown i^X^-in the figure, within which the wire-basket,open at the top for the reception of thegoods, revolves on a vertical shaft; to thisshaft motion is communicated from thehorizontal shaft beneath the tub by meansof bevel-geers. On the extremity of thishorizontal shaft is fixed the driving-pulley,as shown in the figure.) This pulley is of. 2eJ HYDROMETER. 35 the form usually employed on small tilt or trip hammers; a belt passing round this pulley, and continually moving, communicates motion to the pulley -whenever a binder brings the belt in close contactwith its periphery. The binder is attached to an extremity of an oscillating frame, suspended from thetop of the tub, as shown in the figure. The binder presses against the belt so as to communicate motionto the pulley. To stop the motion, the upper end of the oscillating binder-frame is pressed down by ahandle; the binder relieves the belt, and a rope attached to the periphery of a small pulley on thebinder-frame passing over a pulley fixed on the horizontal driving-shaft, and fastened at the other endto the bottom of the tub, acts as a friction-brake to retard the motion of the shaft, and consequently ofthe basket. To keep the binder-frame in extreme positions a movable weight is
