Abstract: An apparatus and methods for limiting the return stroke and modifying the extension stroke of a log splitter. A control rod is translated in the direction of the return stroke of the log splitter. An effort end of a trip arm coupled to the control rod is moved in the direction of the translation and a load end of the trip arm is moved in the opposite direction. The rotation of the load end causes a control lever of the log splitter to move from its rearward position to an intermediate position thereby stopping the return stroke.

Abstract: A method and a device for adjusting a knife assembly of a knife ring to a predetermined knife projection, wherein the knife assembly is designed to be arranged in the knife ring at a chip angle ?, relative to the inside of the knife ring. The knife assembly is formed by a knife holding plate and a chipping knife which are positively connected with one another in a predetermined, relative target position. A knife assembly to be adjusted is provided, wherein the knife holding plate and the chipping knife are displaceable relative to one another. The knife holding plate is displaced in its plane, transversely to its direction of longitudinal extension towards its rear edge, against a first stop. The chipping knife is displaced in its plane against the stop surface of a second stop, until the predetermined knife projection has been reached.

A spring biases the second surface towards the first position.

Abstract: An electrically powered work piece feeder for use with inverted routers or small shapers incorporates improvements in adjustability which enhances accuracy, convenience, and safety in the use of such power tools. The powered feeder element mounts on a table fence and has an inverted roller suspended over the table adjacent a working face. Mounting structure permits positional adjustment of the roller in spatial relation to the power tool cutter and a workpiece on the table so as to propel the workpiece on the table over the power tool cutter and along the working face in the direction of the longitudinal feed axis. An out-feed section may be provided on the fence that includes inner and outer wedge-shaped ramps movable with respect to one another along the longitudinal feed axis and adapted to be locked together, thus allowing slow and precise advancement of the outer ramp toward the router.

Abstract: The adjusting device for a pressure roller of a processing machine has a pivotable support arm carrying a pressure roller adjustable with the support arm from a pressure position into a resting position. The support arm is seated on a support rod that engages a clamping aperture of a pressure roller bracket. The support rod has a first section with noncircular cross section that forms a form-fit section cooperating with the clamping aperture of the pressure roller bracket by form-fit. The support rod has a second section arranged axially offset to the first section and forming a rotary section. It rests against the inner side of the clamping aperture and allows rotation of the support rod about its axis in the clamping aperture. The pressure roller can be pivoted easily into a resting position and/or transverse to the workpiece in the width direction with a constructively simple design.

Abstract: A baseball bat fabricated from a limb of a tree, procured without harvesting any of the tree's trunk. Because of this technique, the process of the present invention is much less wasteful. Many bats can be fabricated from a single tree, without felling the tree itself. The process of fabrication of the present invention is drawn to working with the properties of the harvested tree limb. In this manner, a billet is fabricated on a lathe with its center placed concentric with the center of the tree limb, thusly concentric with the limb's growth rings. By doing so, the growth rings within the limb will not be bisected during fabrication of the billet. When the billet is further turned on a lathe to shape the billet into a baseball bat, the growth rings within the limb will be minimally bisected, thus increasing the strength of the baseball bat of the present invention, as compared to the baseball bats of the prior art.

Abstract: The present invention is generally directed to a bit assembly that includes, but is not limited to: a bit securing sub-assembly including a bit holder member that defines a recess having a first portion extending in a first direction, and a second portion extending from the first portion along a second direction that is not parallel to the first direction; a bit mechanically connected to the bit holder member and positioned within the recess by a fastening hardware that extends through co-axially aligned holes formed in the bit holder member and the bit; and a bit shielding sub-assembly comprising a bit shielding member mechanically connected to and extending from the second portion of the bit holder in a third direction that is substantially parallel to and spaced from the first direction; wherein the bit shielding member is structured, positioned, and/or located to at least partially shield the bit in the first direction.

Abstract: An automated tree cutting assembly includes a collar that may be positioned around a tree. A plurality of climbing units is movably coupled to the collar. The climbing units frictionally engage the tree thereby facilitating each of the climbing units to urge the collar around and up the tree. Each of the climbing units is positionable at selected angle with respect to the collar. Thus, each of the climbing unit units may urge the collar to travel in a spiral along the tree thereby facilitating the collar to climb upwardly and downwardly along the tree. A cutting unit is movably coupled to the collar to cut branches from the tree when the collar is positioned around the tree.

Abstract: A system and method for detecting a defective part and the type of defect formed during stamping operations. The system and method will not only detect the defect but also the nature of the defect and the time at which the defect occurred during stamping operations. Such information is useful not only in quality control but also in isolating a problem which may exist in stamping operations and thus eliminating time for isolating such problems and correcting them. The system and method uses a profile of a properly stamped part to detect a defect, and the root cause of the defect.
