PRONY BRAKE. The lever arm is pivoted at A. The bandcarrying the brake blocks is connected to the lever at D and B. The brake blocks are hollow and pro-vided with internal water circulationfor cooling. The faces of the brakeshoes are smeared with tallow, andno water is allowed on the frictionsurfaces. The block B, to whichthe band is attached, moves in acurved slot, being controlled by the screw and handwheel S. A turn-buckle is provided in the band for tightening the grip of the very close regulation may be obtained by means of the various ad-justments, since the coefficient of friction fluctuates very slightly owingto excellent lubrication and absence of water from the friction is necessary that the center M of the shaft, the pivot at A and thepoint of attachment of the weight to the lever all be in the samestraight line parallel to the ground line.
