    • A field sawbuck having a tree gripper forming a top side fulcrum for holding an end of a felled tree and a tree engaging arm for pivoting the felled tree about the fulcrum to bring the felled tree to an elevated condition whereby the limbs can be removed and the tree can be conveniently cut into desired length without concern for pinching or binding the saw or having the saw blade accidentally contact a support soil for the felled tree as well a method for delivering a felled tree to a field sawbuck that can cantileverly support the felled tree during the process of removing limbs from the tree or during the process of field cutting of the felled tree into firewood lengths.
    • 一种具有树形夹具的现场锯片,其形成用于保持砍伐树的一端的顶侧支点和用于使所述砍伐树绕支点枢转的树结合臂,以使被砍伐的树处于升高状态,从而肢体可以被移除,并且 树可以方便地切割成所需的长度,而不用担心夹紧或装订锯或使锯片意外地接触用于砍伐树的支撑土壤,以及用于将砍伐的树传递到可悬吊支撑砍伐树的田野锯 在从树上去除肢体的过程中或在将砍伐的树木切割成木柴长度的过程中。

    • A pole saw includes a long handle with end adapter, a blade-carrying component pivoted to the end adapter for movement between an extended use position and a handle-adjacent storage position, and a saw blade fixed to the blade-carrying component. The end adapter and holding component are cast aluminum for strength and light weight, and are pivoted together about an offset axis so that the blade and blade-carrying component are positioned adjacent the handle in a partially protected position when collapsed for storage. A folding lock mechanism includes an anchor that engages a saw-holding bolt on the blade-carrying component, and a wing nut that can be tightened to secure the sheath on the blade.
    • 杆锯包括具有端部适配器的长柄部,枢转到端部适配器的刀片承载部件,用于在延伸使用位置和手柄相邻的存储位置之间移动,以及固定到刀片承载部件的锯片。 端部适配器和保持部件是铸铝,用于强度和重量轻,并且围绕偏移轴线枢转在一起,使得刀片和刀片承载部件在被折叠以存储时处于部分保护的位置。 折叠锁定机构包括与刀片承载部件上的锯保持螺栓接合的锚固件以及能够被紧固以将护套固定在叶片上的翼形螺母。

    • A pole saw includes a long handle with cast end adapter, a cast saw-holding component pivoted to the end adapter for movement between an extended use position and a handle-adjacent storage position, and a saw blade pivoted to the holding component for movement between a blade-use position and a blade-protected position. The end adapter and holding component are cast aluminum for strength and light weight, and are pivoted together about an offset axis so that the blade and blade-holding component are positioned adjacent the handle in a partially protected position that is very compact; thus, no disassembly or separate tools are required. A folding lock mechanism includes a hook and pressure pad that cooperate for secure locking in the extended use position. An adjustable set screw eliminates blade looseness when in the use position.
    • 杆锯包括具有铸造端适配器的长手柄,枢转到端部适配器的铸造锯保持部件,用于在延伸的使用位置和手柄相邻的存储位置之间移动,以及枢转到保持部件的锯片,用于在 刀片使用位置和刀片保护位置。 端部适配器和保持部件是铸铝,用于强度和重量轻,并且围绕偏移轴线枢转在一起,使得刀片和刀片保持部件位于手柄附近位置非常紧凑的部分保护位置; 因此,不需要拆卸或分离的工具。 折叠锁定机构包括钩和压力垫,其在延长的使用位置中协作以进行安全锁定。 可调节的固定螺丝在使用位置时消除了刀片松动。

    • A tool for burring the surface of a material. The tool has two sets of oppositely facing toothed blades which are made to move towards each other when the tool is pressed against a surface. Each tooth planes a shallow groove into the surface which results in hook-like burrs or planings rising from each groove. Limiters on the blade stroke ensure that the raised burr is not severed. A spring returns the blades to their start position. The resulting surface therefore has a plurality of shallow, non-piercing stopped grooves with a like plurality of hook-like burrs. Such a modified surface provides increased surface area for electrochemical activity, and a mechanical grip to materials bonded thereto. The tool uses replaceable blade packs which snap into a permanent tool housing. The tool may be operated with a simple hammer blow or it may be rapidly driven into large or small areas of a surface by a manual and/or computer directed punch press.
    • 用于打磨材料表面的工具。 该工具具有两组相对面对的齿形刀片,当工具被压靠在表面上时,它们被制造成朝向彼此移动。 每个齿在表面上平铺一个浅槽,从而导致从每个凹槽上升的钩状毛刺或刨花。 刀片行程上的限制器确保凸起毛刺不被切断。 弹簧将刀片返回到其起始位置。 因此,所得到的表面具有多个具有相同多个钩状毛刺的浅的,非穿孔的停止的凹槽。 这种改性表面提供了电化学活性的增加的表面积,以及与其结合的材料的机械抓地力。 该工具使用可更换的刀片包,卡入永久性工具外壳。 工具可以用简单的锤击操作,或者可以通过手动和/或计算机定向的冲压机快速地驱动到表面的大的或小的区域中。
