Abstract: The mowing apparatus is made up of a long, narrow cutting assembly, a boat and two booms, one on each side of the boat, attaching the cutting assembly to the boat. There is a flotation tank at each end of the cutting assembly and the forward end of each tank is pivotally attached to the aft end of a boom. The forward ends of the booms are pivotally attached to the boat at about gunwale height and well toward the bow. All the pivotal connection axes are horizontal and perpendicular to the vertical plane through the centerline of the boat, allowing the cutting assembly to be raised and lowered between the surface of the water and the bottom of the body of water. The raising and lowering are done by allowing water into the tanks to cause the cutting assembly to sink and forcing the water out of the tanks with air to raise the cutting assembly. The cutting assembly is a sawtoothed blade operating between two sawtoothed plates. The end wise oscillations of the blade are powered by a pneumatic actuator. The tanks are sized and positioned to hold the cutting assembly a specific distance from the bottom when the tanks are flooded and to float the cutting assembly clear of the water when they are full of air. The bottoms of the tanks are shaped so that they plane on the water surface at relatively high boat speeds.

Abstract translation: 割草设备由长，窄的切割组件，船和两个悬臂组成，一个在船的每一侧，将切割组件附接到船上。 在切割组件的每一端都有一个浮选槽，每个罐的前端可枢转地连接到悬臂的后端。 悬臂的前端以大致舷窗高度枢转地附接到船，并且朝向弓。 所有的枢轴连接轴都是水平的，垂直于垂直于船的中心线的垂直平面，允许切割组件在水表面和水体底部之间升高和下降。 升高和降低是通过允许水进入水箱来实现的，导致切割组件下沉并且通过空气迫使水从罐中排出以升高切割组件。 切割组件是在两个锯齿状板之间操作的锯齿刀片。 叶片的末端振荡由气动致动器驱动。 这些罐的尺寸和尺寸被定位成当罐被淹没时将切割组件从底部保持特定距离，并且当切割组件充满空气时将切割组件从水中浮起。 坦克的底部成形为使得它们在相对较高的船速下在水面上平面。
