摘要： A bracket and frame assembly permits attaching and removing a bucket or other tool to and from an arm of an excavator, backhoe, or the like. The bracket and frame assembly comprises two portions, a bracket and a detachable frame. The bracket mounts onto the arm of the implement. The bracket carries a latch member. The bracket can be moved onto a frame on a bucket or other tool, and is latched in place without dismounting from the backhoe, excavator or the like. The latch member can be released, either manually or under power, and then by manipulating the arm, the tool and frame can be removed from the bracket and a new tool mounted. The engaging portions of the frame and bracket are such that as wear occurs, the parts will compensate and remain secured without play or slop.

摘要： A swivel connection for quick attachment bracket equipped excavator booms. The swivel connection has a frame that mounts onto a quick attachment bracket on an excavator or backhoe boom, and the frame pivotally mounts a second attachment bracket about a swivel axis. The second attachment bracket is adapted to fit into a frame on an implement that also is connectable to the bracket on the boom. An implement attached to the second bracket this can be pivoted relative to the frame of the swivel connection. A linear hydraulic actuator is used for controlling the pivoting movement of the second bracket relative to the frame.

摘要： An impact tool has a slidable hammer that is driven by hydraulic oil under pressure inside a chamber. The hydraulic oil is pressurized by a piston driven by compressed gas on the opposite side of the piston from the hydraulic oil. The gas in the gas chamber is compressed by the piston on an initial stroke, and has a large annular chamber holding the gas so that higher average gas pressure can be attained during the power stroke. As the piston is moved to compress the gas, the piston lifts a valve that opens a passage for the hydraulic oil moved by the piston to act on a hammer to impact a breaking tool. The piston is a two part piston that serves to lower the inertia during the final closing of the valve, and thereby reduces impact loads on the valve as it is closed. The valve also is controlled as to its stroke for efficient operation.
摘要翻译：冲击工具具有可滑动的锤子，其在室内的压力下由液压油驱动。液压油由活塞驱动的活塞与液压油在活塞的相反侧被加压。气体室中的气体在初始行程中被活塞压缩，并且具有保持气体的大环形室，使得在动力冲程期间可以获得更高的平均气体压力。当活塞移动以压缩气体时，活塞提升阀，该阀为通过活塞移动的液压油打开通道，以作用于锤子以冲击破碎工具。活塞是两部分活塞，用于在阀的最终关闭期间降低惯性，从而减少阀关闭时的冲击载荷。阀门也被控制为其行程以有效操作。

摘要： A mounting plate that is attachable to an attachment plate of a skid steer loader supports a quick attachment bracket on a forward side thereof. The quick attachment bracket has one part forming a nose, and a saddle spaced from the nose. The quick attachment bracket will move into a receptacle portion of a mounting frame on a tool to be driven by the skid steer loader and will receive another portion of the frame in the saddle. The frame and the quick attachment bracket can be held together with a latch arrangement and then the tool manipulated with the skid steer loader lift arms and attachment plate tilt cylinder. The tool is powered from the skid steer loader in a desired manner.

摘要： A quick attach accessory tool mounting frame is adapted to be mounted onto a quick attachment bracket and held in place. The adapter frame has plates mounting a hub to pivotally mount a powered auxiliary tool. The hanger is formed with spaced plates having upper edges that will abut against portions of the adapter frame to permit only limited pivotal movement of a tool supported by the hanger about a horizontal axis such that the operator can control the position of the auger after the hanger has pivoted against provided stops that limit the pivotal movement of the tool about one axis.
