摘要： A radial arm saw guard for the exposed lower portion of the blade has inner and outer lengths of articulated links fixed to the blade housing to hang on each side of the blade. Each length has a pair of straight links pivotally connected to the front and back of a side of the housing with at least five intermediate links therebetween. The intermediate links are laterally offset a distance equal to their thickness and they are joined by pins extending through longitudinal slots in their ends. Each pin mounts a plastic disk on the side away from the blade, the disks having a diameter at least fifty per cent greater than the vertical depth of the links.

摘要： A method and apparatus for guiding rapidly moving power saw blades to insure accuracy of cut and minimize blade deflection and vibration. A pair of saw guides having flat, parallel faces are mounted in opposed relationship to one another with a saw blade sandwiched between them, the space between the two guides being sufficient to provide respective predetermined gaps between the blade and the face of each guide. Near the center of each guide face is a port through which a pressurized fluid, which is preferably a finely atomized oil-air mixture, is introduced into the respective gaps, such fluid flowing radially outwardly from the port through the gap toward the periphery of the respective guide face. The predetermined size of each gap is such that, for the particular pressure and flow of fluid involved, regions of subatmospheric pressure pursuant to the Bernoulli effect are created on either side of the saw blade in the respective gaps, the suction tending to increase if a respective gap widens and decrease if the gap narrows due to blade deflection. During operation the blade normally remains in a central position of equilibrium between the two guides with the respective suction pressures on each side of the blade balancing one another. Momentary deflection of the blade increases the suction on one side and decreases it on the other, thereby providing a rapidly acting restoring force to return the blade to its central position.

摘要翻译： 一种用于引导快速移动的动力锯片以确保切割精度并最小化叶片偏转和振动的方法和装置。 具有平坦的平行面的一对锯条引导件彼此相对地安装，夹在它们之间的锯片，两个引导件之间的空间足以在刀片和每个引导件的表面之间提供相应的预定间隙。 在每个引导面的中心附近是一个端口，通过该端口将优选为微细雾化的油 - 空气混合物的加压流体引入相应的间隙中，这种流体从端口径向向外通过间隙朝向外周流动 各引导面。 每个间隙的预定尺寸使得对于所涉及的流体的特定压力和流量，在相应间隙中在锯片的任一侧上产生根据伯努利效应的低于大气压的区域，如果a 如果间隙由于叶片偏转而变窄，则相应的间隙变宽并且减小。 在操作期间，叶片通常保持在两个引导件之间的平衡的中心位置，并且叶片的每侧上的相应的吸入压力彼此平衡。 叶片的瞬时偏转增加了一侧的吸力并使另一侧的吸力减小，从而提供了快速作用的恢复力以将叶片返回到其中心位置。

摘要： Cut boards are tipped away from a saw blade and an adjacent splitter by spring members which apply a maximum tipping force to the upper portion of the cut boards. Tipping of the board away from the saw blade is further assured by an abutment which is struck by the cut board as it falls.

摘要： A method and article of fabricating a table comprising the steps of making a lightweight metal frame having a plurality of channels, the edges of which are slightly overlapped by steel plates placed on and connected to the frame. The top surface of the steel plates is machined to render the same coplanar.The frame has orthogonal ribs, and a plurality of bosses formed with apertures therethrough for passage of connecting screws which thread into tapped holes formed in the steel plates. Any excessive length of the screws will be cut off during the machining operation.

摘要： A blade quality monitor for use with cutter reels having specifically identifiable blades utilize a sensor to detect the position of a physical anomaly on the reel. Additional sensors sense the force at the interface between the cutter reel, the material wrapped thereon and the associated pressure roller. The position of the physical anomaly is correlated with the sensed force to determine the magnitude thereof at each blade which is indicative of the condition of the blade with respect to sharpness or intactness.
