摘要： A device for holding a log for sawing comprises a post having fixed thereto a pair of downwardly pointed spikes carried by a plate. A sleeve is slidable on the post and carries four upwardly pointed spikes on a plate and displaced a greater distance from the post 1 than are the spikes fixed to the post. The log is thus held in cantilevered fashion and the weight of the log causes the sleeve to jam in position against the post. The sleeve is provided with a spring to stop is sliding down the post when not in use. The post may be held in a sleeve hammered into the ground or it may be provided with a base so the device is free-standing.

摘要： Embodiments of the present invention provide a jaw apparatus that is tied to a stable anchor (e.g., a vehicle) and that holds wood off the ground in a stable manner to enable cutting by a user. The jaw apparatus can include a main shaft that defines a shaft axis. The main shaft can have a first end and a second end. The first end of the main shaft can have an insertion portion that is configured to be inserted into a trailer-hitch-like receptacle (e.g., a trailer hitch receptacle). The jaw apparatus can include an indentation structure coupled to the second end of the main shaft. The indentation structure can form an indentation, which can have interior surfaces. The interior surfaces can extend upwardly and away from the main shaft. The interior surfaces can be configured to exert upward force on the piece of wood when received in the jaw apparatus. The jaw apparatus can include one or more bars coupled to the main shaft at a bar connection location between the first and second ends of the main shaft. Each of the one or more bars can extend upwardly and away from the main shaft in a direction toward the second end of the main shaft. Each of the one or more bars can have a downward facing surface configured to exert downward force on the piece of wood when received in the jaw apparatus.

摘要： An apparatus for holding firewood and dimension lumber during cutting includes an upright member having a generally triangular shaped plate attached near one end thereof, the plate includes a plurality of steps, each of the plurality of steps having a generally V-shaped portion facing downwards that is attached thereto. The V-shaped portions engage the butt end of any diameter of a log of sufficient size that is placed on the holder and prevents the butt end from becoming dislodged. A serrated plate is attached under the triangular shaped plate that is useful for securing the butt end of small logs and of dimension lumber. A first end of a longitudinal member is attached to the upright member under the serrated plate and extends away from the upright member and is generally perpendicular with respect thereto. A generally rectangular plate having a trough at the top is attached at a second end of the longitudinal member and is useful for the cantilevered placement of logs for cutting thereon. A second longitudinal member is provided at a second end of the upright member that is adapted for placing the holder into a receiver hitch of a vehicle during use. According to a modification the second longitudinal member is eliminated and a base assembly is provided which allows placement of the holder upon the ground surface during use.

摘要： A bracket for supporting a length of lumber adjacent a vertical member such as a stud. The bracket has a central bar to which a pair of end bars are welded. The end bars extend in both directions away from the central bar. The central bar is then placed adjacent the face of a vertical stud and the end bars are sufficiently separated so that the bracket may be rotated a small amount. The bracket is then rotated and a length of lumber is then inserted between the upper and lower bars in a cantilevered member and held securely so that it may be worked on, such as cut to length, along the cantilevered ends. The process of using the bracket is also disclosed and a bracket having four end bars is also disclosed.

摘要： A pair of uprights are provided and disposed in laterally spaced relation. The uprights are interconnected at their lower ends by a horizontal base projecting considerably rearwardly, only, from the uprights and each of the uprights includes front and rear standards. The front standards support a horizontal fulcrum rest extending therebetween and the rear standards support a horizontal abutment member extending therebetween and vertically ajdustable therealong. The abutment member is disposed at an elevation above the elevation of the fulcrum rest and the outwardly projecting portion of the base includes platform structure from which a considerable weight load as may be represented by large rocks may be supported. Elongated logs to be cut may have short base ends thereof engaged beneath the abutment member and over the fulcrum rest with the opposite longer free ends of the logs projecting considerably outwardly from the side of the uprights remote from the sides thereof from which the base projects. The logs may thus be supported in cantilever fashion with their free ends spaced above the ground for cutting by the operator of a power chain saw or the like.

摘要： Cutting horizontal, cantilevering objects of splittable material, such as de-barked tree trunks and the like is carried out with the aid of a guided, endless circulating saw chain (10), the upper cutting part of which is moved from below and upwards through the object. The lower edge portions of the cut surfaces at the cut are allowed to bear against each other under the action of the bending moment of the cantilevering object, while the return portion of the saw chain in the cutting area is kept free from the cut surfaces. The saw chain is guided by a chain guide (12) extending curvilinearly under the object and guides the return part of the chain. The chain guide and the guided return part are both outside and below the object during the whole of the cutting operation, while the upper cutting portion of the chain runs straight between the end points of the curved portion of the chain guide.Towards the end of the cutting operation, the part of the object not yet sawn through is subjected solely to short-duration tensional stress and substantially not to bending stress, whereby splitting the material is avoided.

摘要： A log lifting device is described that includes an upstanding post with an attached flexible strand. The flexible strand, such as a chain, releasably connects the post to a jack. Guide members on the post cause the flexible strand to extend generally parallel to the post for a substantial portion of the length of the post. The flexible strand may include a thin, rigid extension at one end to enable the strand to be threaded under a log to be lifted. The end passed under the log to be lifted is then attached to a jack. The log is raised upwardly generally parallel the length of the support member in response to an upward force applied by the jack.
