    摘要： A balanced essentially vibration-free hand-grippable fluid powered reciprocating blade cutting tool intended primarily for cutting poultry, fish and meat for processing. The tool includes a hollow handle which functions as a motor housing. Fittings are provided for connecting the housing to a source of fluid under pressure and for exhausting fluid from the housing. A reciprocable cutting blade extends forwardly from the handle. A fluid actuated motor within the handle housing includes a pair of aligned piston assemblies of approximately equal weight. The pistons are reciprocable in opposite directions. The cutting blade is secured to one of these pistons. A control valve and fluid flow passages within the housing and associated with the fluid inlet fitting permits fluid to be directed alternately to the inner and outer sides of the pistons for causing the pistons to alternately move toward one another and away from one another. A manually operable trigger controls the flow of fluid into the housing. The angle of the cutting blade relative to the handle is variable to further reduce fatigue and other problems associated with rotation of the wrist, which is a contributing cause of carpal tunnel syndrome.

    摘要翻译： 平衡的基本上无振动的手动抓握流体动力的往复式叶片切割工具，主要用于切割禽类，鱼类和肉类进行加工。 该工具包括用作电动机壳体的空心手柄。 提供了用于将壳体连接到压力下的流体源并用于从壳体排出流体的配件。 可往复切割刀片从手柄向前延伸。 手柄壳体内的流体致动马达包括大致相等重量的一对对齐的活塞组件。 活塞可在相反方向往复运动。 切割刀片固定在其中一个活塞上。 壳体内的与流体入口配件相关联的控制阀和流体流动通道允许流体被交替地引导到活塞的内侧和外侧，以使活塞彼此交替地彼此移动。 手动操作的触发器控制流入壳体的流体。 切割刀片相对于把手的角度是可变的，以进一步减少与手腕旋转相关的疲劳和其它问题，这是腕管综合症的一个原因。

    摘要： A portable and high-speed tool reciprocator for small tools, such as files, cutters, burnishing and polishing stones, leathers and the like, of a size easily held in one hand of an operator; fluid driven, preferably by a pneumatic fluid, the length of the reciprocatory stroke of which reciprocator may be adjusted, while in operative reciprocation, without the reorganization of its parts or the employment of extraneous gear, and the reciprocated tool may be selectively controlled to be either free or locked against rotation about its axis of reciprocation, while in operative reciprocation, without the reorganization of the reciprocator parts or the employment of extraneous gear, thus to enable the tool and its working face to move angularly relative to its axis of reciprocation and the holder, when free floating, or, when locked, to dispose the tool and its working face at some desired angle to tool reciprocation and the holder.

    摘要： A HYDRAULIC REVERSING SYSTEM FOR A RECIPROCATING WORKING MEMBER WHICH IS CONNECTED WITH A POWER CYLINDER RECEIVING A MAIN PISTON WHICH SUBDIVIDES THE CYLINDER INTO DISPACEMENT CHAMBERS. THE MAIN CONTROL VALVE COMPRISES A PISTON WITH A CENTRAL SPOOL SEPARATING TWO WORKING CHAMBERS FROM ONE ANOTHER THE WORKING CHAMBERS BEING CONNECTED TO THE DISPLACEMENT CHAMBERS OF THE MAIN CYLINDER. IN ADDITION, A PAIR OF CONTROL SPOOLS SEPARATE THE MAIN CHAMBERS OF THE VALVE FROM CONTROL CHAMBERS WHICH ARE RESPECTIVELY CONNECTED BY HYDRAULIC IMPULSE TRANSMITTERS COOPERATING WITH THE MOVABLE MEMBER FOR ALTERNATE OPERATION ON RECIPROCATION THEREOF. IMMEDIATELY UPON TRIPPING OF ONE OF THE IMPULSE GENERATORS, AND OIL FLOW FROM THE MAIN VALVE INLET TO THE CORRESPONDING CONTROL COMPARTMENT IS TERMINATED AND THE SPOON VALVE SHIFTED IN THE OPPOSITE DIRECTION TO REVERSE THE FLOW OF FLUID TO THE DISPLACEMENT COMPARTMENTS OF THE MAIN CYLINDER. AFTER AN INITIAL CLEARANCE IS FORMED IN COMMINICATION WITH THE CONTROL CHAMBER, THE MAIN HYDRAULIC PRESSURE SERVES TO BIAS THE CONTROL VALVE.
