again as it is rotated in the opposite direction 

 to pull the hose in. Thus the electrical con- 

 nection need not be interrupted when the drum 

 is rotated. The end of the powerline is con- 

 nected to the capacitor starter, which is 

 located near the winch, and the capacitor in 

 turn is plugged into an A.C. outlet on the deck 

 of the vessel. 



Rotation of the drum is controlled by a 

 reversible 3/4-hp. A.C. gear motor mounted 

 on the base of the winch stand. The combina- 

 tion reduction gear and chain- sprocket drive 

 to the axle rotates the drum at about 2 r.p.m., 

 which reels the hose in or out at a constant 

 rate of 20 feet per minute. Braking is auto- 

 matic. The motor shaft is always locked by a 

 built-in brake when the control lever is in 

 the off position. 



The guide wheel (fig. 7) is actually a roller 

 cage designed and built specifically for this 

 apparatus. It consists of two horizontal and 

 two vertical rollers made of 2-inch diameter 

 PVC tubing with sintered nylon bushings. The
