Abstract: A rectangular base plate has a arcuate opening within one side terminating in a narrow arm which projects within the opening and adjacent the one side, with the tip of the arm acting as the vertical pivot point for the plate outside and free of a band saw blade with the plate resting on the band saw table. A pivot pin fixed to a slide mounted to the table forms the pivot axis for the plate at the inner end of the projecting arm with the slide being movable towards and away from the band saw which passes through a semicircular opening within the band saw table. An Lshaped bracket adjustably mounted to the base plate carries a Vblock pipe holder whose angle of inclination may vary and which supports the pipe to be severed such that the pipe axis intersects the base plate pivot axis. By adjusting the position of the slide and the angle of inclination of the V-block, the pipe may be cut at a desired angle and radius of cut by swinging the plate about its pivot axis.

Abstract translation: 矩形基板在一侧内具有圆弧形的开口，终止于窄臂中，该窄臂突出在开口内并且邻近一侧，臂的尖端作为板外侧的垂直枢轴点，并且没有带锯片 板放在带锯台上。 固定到安装到桌子上的滑块的枢轴销在突出臂的内端处形成用于板的枢转轴线，其中滑动件能够朝向和远离通过带锯台内的半圆形开口的带锯移动。 可调节地安装到基板的L形支架携带V形块管支架，其倾斜角度可以变化，并且支撑要切断的管道，使得管轴线与基板枢转轴线相交。 通过调整滑块的位置和V形块的倾斜角度，可以通过围绕其枢转轴线摆动板来将管切割成所需的角度和切割半径。
