Excerpt from Duffy's Wave Motor: As a Source of Power for Various Purposes Figure 2 is a plan of the tower O, and water-reservoir R in four compartments. For the purpose of guiding the ballasted poised basin, and prevent ing it from swinging round with the buoy, and also to hold it rigid to the buoy and to stop the operation of the air-pumps while making repairs or for other cause, there is provided a guiding and braking device, as shown in Figures 1 and 3. A brake, bl, having a jawed recess in its end, is secured to the top of the basin 011 its four sides; and shoes, N, are attached to the shell of the buoy. The recess in the brake fits loosely on the shoe, and guides the basin and prevents it from swinging; and when it is necessary to hold the basin rigid to the buoy, the brake is screwed inward to impinge on the shoe.
