  • Axe
    Patent number: 8925207
    Abstract: An axe comprising a blade (3) provided with a cutting edge (6) at one end, and a handle (2), and in which the center of gravity of the axe is located at a distance from the cutting edge (6) of the axe and lies in a center-of-gravity plane (C) of the axe located at a distance from a blade plane (B) of the axe parallel with both the center-of-gravity plane (C) and a normal working motion plane (W) of the axe, and in which the cutting edge (6) of the blade and the center of gravity of the axe are arranged to cooperate when the blade (3) hits wood and the cutting edge (6) of the blade partly penetrates into the wood such that at least some of the impact force of the blade (3) is converted into a rotational motion and a motion of the blade (3) in a curvilinear trajectory, the blade (3) is attached to the handle (2) so that the handle (2) is uncircled by the blade (3).

  • Patent number: 8347928
    Abstract: Provided is a wood splitter having a support element, a first elongated element, a second elongated element, and wood splitting components. A support element may be a first elongated element and a second elongated element engaged to the first elongated element. The first elongated element may be subject to a first pre-stress load. The first pre-stress load may be a first moment. The a second elongated element may be engaged to the first elongated element and may be subject to a second pre-stress load. Wood splitting components may be engaged with at least one of a first elongated element or a second elongated element, may be adapted to operate to split wood, and may be adapted to apply an operational load during operation to the first elongated element. The operational load may at least partially relax the first moment.

  • Publication number: 20110061767
    Abstract: An apparatus includes a carriage, a first tooth, a second tooth, a feed block and a drive element. The first and second teeth are shaped for breaking bonds and attached to a first side of the carriage. The first and second teeth are spaced apart and generally parallel to each other. The drive element moves the carriage away from the feed block so that the first and second teeth break bonds when they encounter them. A method for removing a bonded component from a structure includes positioning a tool having first and second teeth between the component and the structure. The teeth are positioned between trailing edges of the component and the structure. The method includes driving the teeth from the trailing edges of the structure towards a leading edge of the structure to break bonds between the component and the structure so that the component can be removed.

  • Patent number: 7584773
    Abstract: A wood-splitting tool includes a penetration portion having a penetrating end and a wedge portion having an impact end. The penetration portion is configured for penetration into a piece of wood. The penetration portion includes two penetration surfaces diverging generally from each other at an inclusive angle generally from the penetrating end. The wedge portion includes two wedge surfaces generally contiguous with the diverging penetration surfaces and diverging from each other at an inclusive angle, which is greater than the inclusive angle of the diverging penetration surfaces. The wedge portion is primarily configured to impart a wedge force to the wood. The penetration portion has a length that is greater than half the length of the tool, which allows the tool to penetrate the piece of wood without significantly imparting a wedge force until the tool penetrates deep enough to allow the wedge portion to engage the wood.

  • Patent number: 7188646
    Abstract: A splitting wedge is provided for splitting wood. The wedge includes an upwardly facing impact surface, a collar adapted to slidably engage a vertical guide track and a downwardly facing cutting edge. The wedge is adapted to slide down the guide track and cut into an object to split, such as a wood log, when struck on the impact surface. The collar can include a bore to slidably engage a tubular guide track. The impact surface is off-set from the wedge towards to the collar.

  • Patent number: 7159627
    Abstract: A manual log splitting device for splitting a log has a first assembly including a base plate for resting of the log and a first upright extending upwardly from the base plate. A second assembly having an upright sleeve, impact plate, and wedge assembly, is axially and slidably mounted on the first upright with the upright sleeve. A user splits the log by causing the second assembly to move towards the base plate such that the wedge assembly passes through and splits the log. A receptacle abuttingly engages the upright sleeve and the base plate when the second assembly is in a resting position where the wedge assembly is slightly spaced apart from the base plate. Thus, movement of the second assembly towards the base plate beyond the resting position, and contact therebetween, is prevented.

  • Patent number: 7104296
    Abstract: A log splitting system comprises a splitter box, having entrance and discharge sections, each with top, bottom and sidewalls, and open entrance and discharge ends. A first set of cutting blades in the entrance section divides that section into at least two, first sections. A second set of cutting blades in the discharge section further divides each first section into at least two, second sections. The entrance and discharge sections are hinged at the top and pivot apart for cleaning and service. A ram assembly with a force applying surface contacts a log with the first set of cutting blades. The ram member's surface has surface portions, each sized to fit into one of the splitter box's first section, to further contact the log with the second set of cutting blades, splitting the log into at least four pieces.

  • Patent number: 7040362
    Abstract: A log splitter comprising: a base; a lever having one end portion hingably attached to the base; a wedge slidably attached to a hinged end portion of the lever, to slidably reciprocate along the lever when the lever is swung; a log support for a cut log; and, an upper end log restraint slidably positioned on the lever, said log restraint having a pawl, and the lever having teeth therealong, so that the log restraint can only slide towards the cut log. When the lever is swung down the wedge is forced into the cut log, and when the lever is lifted the wedge is slidably pulled back along the lever thereby pulling the now partially split log so that the upper end log restraint freely slides along the lever. When the lever is again pushed downwardly the cycle is repeated. The lever may be pushed with a foot pedal.

  • Patent number: 6854945
    Abstract: In combination, an elongated tool having a striking end and a tapered insertion end and a drift pin cap. The drift pin cap includes a cap body having an upper end, a lower end and at least one side wall extending between and connecting the upper end and the lower end. A drift pin receiving cavity is formed in the lower end of the cap body which extends upwards towards the upper end within the cap body, the pin receiving cavity having a diameter smaller than a diameter of the cap body. The pin receiving cavity is operative to fit over and be retained on the striking end of the tool such that when the tool is impacted by a driving device, the drift pin cap is interposed between the tool and the driving device to prevent damage to the tool yet still permit driving of the tool.

  • Patent number: 6533004
    Abstract: A wood-splitting impact tool with an enhanced wood-splitting function by virtue of its improved penetration and its reduced recoil. Improving the penetration of the wedge is achieved by fabricating the wedge of aluminum, titanium, graphite composite or alloys thereof, or any lightweight material that has rare energy transfer capability. Penetration into wood is further enhanced by using a frictionless or smooth surface coating on the penetrating surfaces of the wedge, such coating being PTFE, Teflon®, or anodized aluminum. The wedge and its cutting edge surfaces can be anodized to toughen as well as smooth all surfaces subject to deformation. The surface of the wedge is structurally decreased in recoil by interrupting the metal surface with small, periodic, directional or stepped abutments.
