  • Patent number: 8579014
    Abstract: A conveyor for moving hot material at temperatures on this order of 1000° F. or higher along a conveyor trough receiving the material has one or more coolant liquid flow vessels extending over but spaced from the outer surface of a trough inner wall to indirectly cause cooling of the inner wall. A heat transfer path is established between a separate coolant flow vessel and the hot trough defined by a packed together mass of heat conductive beads interposed to controllably transfer heat into the coolant liquid flowing through the flow vessel to prevent boiling of the coolant while allowing heat to be transferred from the through into the coolant in the separate flow vessel. The arrangement of a mass of heat conductive beads is also used to provide a non rigid mechanical support of fluid carrying tubing, the support having a predetermined thermal conductivity.

  • Patent number: 8322385
    Abstract: A double chain saw arrangement which has diametrically oppositely extending chain saws powered by a single motor driving two sprockets on said hub, each engaged with an associated chain saw chains on each chain saw bar mounted to the hub. A series of hooked capture pieces project from one side of the chain saw bars in a plane parallel to the chain saw bars, which pieces act to cause brush and limbs to be captured and forced into contact with the saw chains to be cut thereby.

  • Patent number: 7878463
    Abstract: A shaft seal mounting assembly and method including a pair of semicircular ring segments assembled onto a shaft with a seal held therein engaging the shaft. A flat surface on the base structure holding the ring segments is held against a wall surface extending around a hole through which the shaft passes by a camming arrangement comprised of slotted studs fixed to the wall and received in openings in the base structure. A slotted locking slide bar is received in each stud slot and captured by a cross pin extending through the slot in a respective bar, the side bar slot sloping so as to cam the base structure towards the wall surface when the locking slide bar is driven through the stud slot.

  • Patent number: 7815391
    Abstract: A connector and method for joining one end of a first wood member such as a wood log or beam to a side of a second wood member involving metal sleeves secured in aligned holes in a respective member with a protruding one of the sleeve slidable into the other sleeve. A bolt is threaded into an internally threaded element on the inner end of the sleeve in the first member and advanced to pull the members together. The sleeves are secured in the holes with spike features driven out into the surrounding wood. Alternatively, a tee connector has a plate portion fitting into a slot extending through aligned holes in the plate and one end of the first member. A cross plate is held against the one side of the other member with thread fasteners.

  • Publication number: 20100059205
    Abstract: A conveyor for moving hot material at temperatures on this order of 1000° F. or higher along a trough receiving the material has one or more cooling liquid flow vessels extending over but spaced from the outer surface of a trough inner wall to indirectly cause cooling of the inner wall. A heat transfer connection conductively interconnect the vessel and the inner trough wall such as interposed thin webs or plates, or alternatively a mass of conductive beads interposed to controllably transfer heat into the cooling liquid flow vessel. A series of wear plates are clamped to a pushing side of a helical tube of an auger type conveyor, which tube can also receive a flow of cooling liquid. The arrangement of a mass of conductive beads is used to provide a non rigid mechanical support of fluid carrying tubing, the support having a predetermined thermal conductivity.

  • Patent number: 7207610
    Abstract: A wood handling clam having a pair of hollow curved jaws constructed of side walls and inside and outside covers welded thereto. A hollow carrier housing on which the jaws are pivoted at their upper ends has a downwardly extending center portion received into a slot formed into the upper end of each jaw. A tubular pivot pin extends through each upper end of each of the jaws and a pair of carrier housing side plates, as well as the through the down central portion of the carrier housing. Tubular cross shafts in the jaws and housing anchor devises for mounting each end of a power cylinder for each jaw extending into the slot in the upper end of each jaw.

  • Patent number: 7153086
    Abstract: A turnover apparatus and method for inverting articles such as lumber or board pieces being conveyed sideways on two or more conveyor chain loops in which each article is advanced on the conveyor chain loops by speed up belts engaging the underside of the articles to force a leading side against a pair of lugs mounted on a respective conveyor chain loop, the article thereafter flipped up to an on edge position by flipper arms also mounted on the conveyor chain loops which each engage an adjustable cam ramp at a turnover station, the article thereafter tipped over backward by being driven by the speed belts against an elevated overhung trailing edge on the lugs to complete the turnover. Optional pivoted let down elements may be arranged to engage the trailing side of the articles to controllably lower the same by motion induced by a second cam ramp at the turnover station.

  • Publication number: 20040055738
    Abstract: A conveyor for moving hot or cold material along a trough receiving the material. One or more heat transfer fluid flow tubes extend over the outer surface of a trough liner wall to indirectly cause cooling or heating of the liner wall. Fins or angled thin metal strips conductively interconnect the tube or tubes and the liner wall. A series of wear plates are clamped to a pushing side of a helical tube of an auger type conveyor, which tube can also receive a flow of heat transfer fluid. A mass of conductive beads can alternatively be used to transfer heat into or from the heat transfer fluid.

  • Patent number: 6199306
    Abstract: A high efficiency snow thrower relying on a cutting action to create snow chunks which are conveyed and discharged, using one or more cutter bar arrays arranged in the front opening of a housing and an auger member which also has a cutting edge on helically wound strips splitting the packed snow and conveying chunks of the same while importing significant velocity to an impeller pocket at the center of the helical strip, which discharges snow chunks out through a discharge chute.
