Abstract: A mechanized coping saw has a frame and handle attached thereto, the frame including a U-shaped portion with opposite leg sections having outward ends, a cavity formed within the U-shaped portion, and apertures proximate the outward ends of the leg sections which open into the cavity. An endless blade travels through the cavity of the U-shaped portion around rotating elements with a portion of the blade extending straight between the leg sections to define an exposed blade cutting section, A power drive system drives the blade through the cavity. The invention uses a pair of guide rollers which are placed along the profiled edge of a molding piece to steadily guide the blade cutting section for precise coping of the molding piece. The rollers are adjustable to provide for a variety of different cutting angles and situations. Another embodiment utilizes an elongated arced guide arm to extend longitudinally along the exposed blade cutting section for guiding and steadying the blade, Another embodiment includes a blade section cover pivotally mounted to move outwardly from the blade cutting section to expose the blade during coping.
Abstract translation: 机械化的应对锯具有附接到其上的框架和手柄，框架包括具有相对的腿部的U形部分，其具有向外的端部，形成在U形部分内的空腔和靠近腿部的外端的孔， 进入腔。 环形刀片通过围绕旋转元件的U形部分的空腔行进，其中刀片的一部分在腿部之间直线延伸以限定暴露的刀片切割部分。动力驱动系统通过腔体驱动刀片。 本发明使用一对沿成形件的成型边缘放置的导辊，以稳定地引导刀片切割部分，以精确地对准成型件。 滚轮是可调节的，以提供各种不同的切割角度和情况。 另一个实施例利用细长的弧形引导臂沿着暴露的刀片切割部分纵向延伸以引导和稳定刀片。另一实施例包括枢转地安装成从刀片切割部分向外移动以在应对期间暴露刀片的刀片部分盖。
