  • Patent number: 4269243
    Abstract: An improved veneer lathe which cuts sheets of veneer from a turned log. A torque is applied to the log both by way of the spindle chuck holding its axial ends and by way of its outer periphery. During the cutting operation, the primary cause of log rotation is designed to be an external force applied to the log periphery by using an idling mechanism including a torque limiter, an overrunning clutch, etc.

  • Patent number: 4270161
    Abstract: Lighting apparatus comprising a long span lightweight luminaire beam with a cross section that is substantially in the shape of an equilateral triangle and is formed in multiple sections secured together. One apex of the triangle is pointed downwardly. The side panels of the beam are used as mounting and reflecting surfaces for fluorescent lights or the like, while the ballast and wiring are mounted inside the beam to protect them from weather. The mounting hole for the ballast also serves as the access hole for assembly of the span, and the ballast may be inverted in its mounting for servicing. The beam is supported in an elevated, substantially horizontally extending position by one or more support posts. This apparatus is particularly advantageous for use in illuminating large outdoor areas such as tennis courts.

  • Patent number: 4266434
    Abstract: A power take-off mechanism which converts rotational motion to a variety of available rotating, reciprocating and/or oscillating motions. The device comprises a rocking frame within which is mounted a rotating shaft on which is mounted an unbalanced weight. One end of the shaft is connected through a constant velocity type joint to a power source and the opposite end of the shaft rotates within a restraining ring or area on the frame. The rotating unbalanced weight transmits force through the shaft to the rocking frame which is free to pivot or move rotationally about one axis and at the same time to reciprocate axially along the same axis. Power may be taken off from various points on the frame as either reciprocating motion, reciprocating motion with a cyclicly reversing twist, circular motion inscribed on a plane of rotation, or eliptical motion inscribed on a plane of rotation.
