Abstract: Provided is a jaw crusher driving device in which a driving torque can be transmitted reliably to a rotation driving shaft to perform a crushing operation by strongly fixing a hydraulic pressure motor between a body frame of a jaw crusher and a flywheel. The jaw crusher includes a fixed tooth, a movable tooth, a rotation driving shaft rotatably supported on a body frame, and a pair of flywheels provided in the rotation driving shaft. The driving device includes: a hydraulic pressure motor in which a rotation shaft portion can rotate in relation to a motor body when pressure fluid is supplied; a connector for connecting one flywheel of the pair of flywheels and the rotation shaft portion; and a torque arm provided between the body frame and the motor body so as to prevent the motor body from rotating about an axis of the rotation driving shaft.

Abstract: A heel member for a push block used with a woodworking apparatus comprises a side surface that is disposed substantially perpendicular to a bottom surface of the push block and is spaced apart from and end of the push block. A heel position adjustment mechanism is operatively connected to the heel member to adjust the heel member and a bottom edge of the heel member to multiple selected positions relative to a bottom surface of the push block. The heel member may have an inclined surface abutting an incline surface at the end of the push block and female and male guides along both inclined surfaces in mating relationship.

Abstract: A method for making a decorative multilaminar veneer with accentuated curvilinear shapes consists of the steps of: obtaining sheets of wood from a log of wood or from a block of multilaminar wood; superimposing and permanently sticking the sheets of wood on top of one another to form a plurality of packets of sheets of wood; providing a plurality of male molds and at least one female countermold, wherein each male mold has a convex curvilinear profile with different curvature radiuses of one mold with respect to the other and wherein the female countermold has a concave curvilinear profile; arranging, pressing and permanently sticking together several packets, in sequence and superimposed, between the female countermold and in sequence the male molds to deform in a curvilinear manner the packets, replacing in sequence, upon the reaching of a preset height of the superimposed, joined and deformed packets a male mold with a profile with a greater curvature radius with a successive male mold with a profile with
