摘要： A reciprocating, air-driven mechanism comprising, in one embodiment, a center-seeking piston connected to an oscillatably pivoted linkage which drives a material working tool. Air is delivered to the opposite ends of the piston at different stages of its reciprocation through the use of peripheral grooves on the piston and selected passages in the surrounding cylinder. An operator-actuated valve includes passages through which air may initially be delivered to one end of the piston so as to move it off center when operation of the tool is initiated. In a second embodiment, the air may be delivered to the piston by means of a single valve which is actuated by a piston-driven system to alternately communicate each piston-end with incoming and exhaust air passages. In either embodiment, as the piston is reciprocated, air exhausted from the non-driving end of the piston flows between a bearing plate and a shoe bar to create an air bearing and to pressurize the interior of the tool to prevent contamination thereof by particles of the material upon which the tool is working.
摘要翻译：一种往复式的空气驱动机构，在一个实施例中，包括一个连接到可驱动物料作业工具的可摆动的枢转连杆的中心寻求活塞。通过使用活塞上的周边槽和周围气缸中的选定通道，空气在其往复运动的不同阶段被输送到活塞的相对端。操作者致动阀包括通道，空气最初可以被输送到活塞的一端，以便在启动工具的操作时将其移离中心。在第二实施例中，空气可以通过由活塞驱动系统致动的单个阀输送到活塞，以使每个活塞端与进入和排出的空气通道交替地连通。在任一实施例中，当活塞往复运动时，从活塞的非驱动端排出的空气在支承板和鞋条之间流动，以产生空气轴承并对工具的内部加压以防止其被颗粒污染工具正在工作的材料。

摘要： A three-bladed pneumatically driven shear in which the central, moving blade is provided with a transverse and longitudinal curved surface on its lower edge to reduce frictional contact between the blade and the material to be severed and to allow the cutter to make relatively small radius cuts in the material being severed. The transverse curvature on the bottom of the blade prevents it from biting into the material and inhibiting the turning of the cutter along a radius on the material being severed. The side, fixed blades are beveled on the lower surfaces in order to allow the operator to rotate the cutter about a vertical axis passing through the point of sharing without damaging the workpiece or the cutters while shearing along a curve. One of the side blades is positioned on the cutter so as to extend slightly below the bottom of the other side blade, thereby causing the center blade to commence cutting at one side of the cutter before the other. This facilitates the removal of the chip formed by the severed material by forcing it to curl off to one side away from the cutter. The central blade is formed so as to extend beyond the ends of the side blades in order to facilitate initial engagement with the material to be severed.
摘要翻译：三叶式气动剪切机，其中中央动叶片在其下边缘上设有横向和纵向弯曲表面，以减少叶片与要切断的材料之间的摩擦接触，并允许切割器制作相对较小的半径切割材料被切断。叶片底部的横向曲率阻止其咬入材料，并阻止切割器沿被切断材料的半径转动。侧面的固定刀片在下表面上是斜面的，以便使操作者能够绕着垂直的轴线旋转刀具，而不会在沿曲线剪切的同时不损坏工件或刀具。一个侧叶片位于切割器上，以便稍微延伸到另一侧叶片的底部的下方，从而使得中心叶片在切割器的另一侧开始切割。这有助于通过迫使其卷曲到远离切割器的一侧来去除由切断的材料形成的切屑。中心叶片形成为延伸超过侧叶片的端部，以便于与要切断的材料的初始接合。
