    Abstract: A saw blade for a tree felling head has three tipped teeth in which only one tip of each tooth is exposed outside of the blade disc. Around the circumference of the blade, teeth with tips exposed on the upper side of the blade alternate with teeth having tips exposed on the lower side of the blade. Axes of the teeth are tangent to radii of the disc and angled upwardly or downwardly relative to the plane of the disc, and mating surfaces on the teeth and disc at 45null to the plane of the disc abut against rotation and loading of the teeth.

    Abstract: A tool for cutting a predetermined molding pattern into a work piece as it is longitudinally advanced. A molding head is adapted to be mounted to the output shaft of a motor. The head is generally-circular and includes at least one arcuate cutout in its peripheral edge for receiving a generally-circular cutter unit. The arcuate cutout is greater than semicircular so that the center of the unit lies within the peripheral edge and is therby protected from radial travel. A bayonet-type fixture and an alognment screw are provided for engaging the cutter unit to the molding head whereby multiple devices protect the operator from violent disengagement of the cutter unit from the head during high speed cutting.

    Abstract translation: 用于将预定模制图案纵向推进到工件中的工具。 成型头适于安装到电机的输出轴上。 头部是大致圆形的并且在其周边边缘中包括至少一个弧形切口，用于接收大致圆形的切割器单元。 弧形切口大于半圆形，使得单元的中心位于周边边缘内并且被保护免受径向行进。 提供了一种卡口式夹具和一个隔离螺钉，用于将切割器单元接合到模制头上，由此多个装置在高速​​切割期间保护操作者免受刀具单元与头部的猛烈分离。
