    • An improved vertical gang saw is provided for sawing blocks of stone or the like. By this new design, the vertical saw frame is slued or swung about the center of the blades during each reciprocating movement. This design combines the following features:(a) the vertical frame (5) being supported at the center (13);(b) straight line guides (6 and 7) connected to said frame and positioned respectively at one end (21) and in the center (13) of the saw frame (5); and(c) the pivotal point of the straight line guide (6) being moveable perpendicular to the stroke of the frame and dependent thereupon.The perpendicular movement of the straight line guides can be accomplished by connecting them with a cam (10) which is driven off of the flywheel (3). Through this combination, all of the saw blades cut the stone block workpiece in both the up and down directions.
    • 提供了一种用于石头等的锯切块的改进的垂直组合锯。 通过这种新设计,在每次往复运动期间,垂直锯框架围绕叶片的中心进行切割或摆动。 该设计结合了以下特征:(a)在中心(13)处支撑的垂直框架(5); (b)连接到所述框架并分别位于锯框架(5)的一端(21)和中心(13)的直线导轨(6和7); 和(c)直线引导件(6)的枢转点可垂直于框架的行程而移动并依赖于此。 直线导轨的垂直运动可以通过将其与从飞轮(3)驱动的凸轮(10)连接来实现。 通过这种组合,所有锯片都沿上下方向切割石块工件。
