摘要： Tongs for harvesting oysters including two grated baskets pivoted to a support frame in opposed relation for actuation between open and closed positions by a hydraulic motor mounted on the support frame to directly drive one basket which in turn is connected to the other basket by a linkage for driving the latter in unison. The tongs are raised and lowered in water from a boat by a cable driven by a hydraulically operated switch. Operation and control of the tongs and the winch is achieved through a hydraulic system including foot pedals which actuate control valves for supplying and exhausting hydraulic fluid to and from the motors associated with the tongs and the winch.

摘要： AN IMPROVED OYSTER DREDGING ARRANGEMENT COMPRISING AN OYSTER DREDGE AND AN OYSTER DREDGE DUMPING AND LAUNCHING STRUCTURE. THE OYSTER DREDGE IS DRAGGED ALONG THE OCEAN BOTTOM AND OYSTERS ARE SCOOPED INTO A BASKET PORTION THEREOF. WHEN THE BASKET IS FULL THE OYSTER DREDGE IS PULED OVER THE OYSTER DREDGE DUMPING STRUCTURE AND COOPERATIVE MEANS ARE PROVIDED ON THE DUMPING STRUCTURE AND THE BASKET SO THAT CONTINUED PULLING UP OF THE OYSTER

DREDGE AUTOMATICALLY OPENS THE BASKET TO ALLOW THE CONTENTS THEREOF TO FALL BY GRAVITY ONTO THE DECK OF THE BOAT. WHEN THE DREDGE IS EMPTY AND TENSION RELAXED ON THE HOISTING MEANS THE OYSTER DREDGE IS LAUNCHED OVERBOARD BY THE OYSTER DREDGE DUMPING AND LAUNCHING STRUCTURE SO THE PROCESS MAY BE REPEATED.
