A rotatable connector pin assembly is disposed within an opening in an adapter nose, with opposite ends of the pin portion of the assembly extending outwardly beyond opposite sides of the adapter nose in axially fixed orientations relative thereto, and is used to captively and releasably retain a replaceable excavating tooth point on the nose. The configuration of the opposite pin ends permits the overall pin assembly to remain in the adapter nose during removal of the point and replacement thereof, with the pin being rotatable between a first orientation in which its ends permit removal of a point from the nose, or installation of a point on the nose, and a second orientation in which the opposite pin ends block removal of the point from the adapter nose.

Excavating tooth point/adapter assembly methods

A connector pin assembly is disposed within an opening in an adapter nose, with opposite ends of a rotatable pin portion of the assembly extending outwardly beyond opposite sides of the adapter nose in axially fixed orientations relative thereto, and is used to captively and releasably retain a replaceable excavating tooth point on the nose. The configuration of the opposite pin ends permits the overall pin assembly to remain in the adapter nose during removal of the point and replacement thereof, with the pin being rotatable between a release orientation in which its ends permit removal of a point from the nose, or installation of a point on the nose, and a locking orientation in which the opposite pin ends block removal of the point from the adapter nose.

Excavating tooth point/adapter assembly

An elongated excavating tooth assembly includes a replaceable tooth point and an adapter structure comprising (1) an intermediate adapter having a front end nose complementarily received in a rear end pocket of the point and captively retained therein by a first connector pin structure, and (2) a main adapter having a front end nose complementarily received in a rear end pocket of the intermediate adapter and captively retained therein by a second connector pin structure, and a rear end operatively securable to an excavating bucket lip. Special configurations of the point and adapter portions of the assembly, including horizontally elongated oval configurations of the noses, horizontal orientation of the connector pins, nose stabilization bosses at the nose connector openings, and complementarily scalloped adapter and point interface areas, provide the assembly with reduced size and improved strength, wear and operational characteristics.

A specially designed quick coupler is representatively used to removably attach an excavation bucket to the outer boom end of an excavator. A top portion of the quick coupler is pinned to the outer boom end and has a bottom portion with spaced apart recesses configured to releasably receive portions of stick and curl pins on the bucket. An arcuate latch hook is translationally drivable by a hydraulic cylinder assembly toward one of the implement pins to releasably lock it in its associated coupler recess in a manner also captively retaining the other implement pin in its associated coupler recess. Stop structures oppose the latch hook and, using a simple shim arrangement, may be translationally shifted toward and away therefrom to easily adjust the coupler for wear and/or changes in the implement pin spacing. A redundant safety system is incorporated in the coupler and serves to hold the latch hook in its locking position. The safety system includes hydraulic and mechanical locking mechanisms and a spring structure resiliently biasing the latch hook toward its locking position.

A sawing system is provided having a material conveyor for moving lengths of wood stock through the sawing system. According to one aspect of the invention, the material conveyor is preferably inclined upward from a frontal loading end to facilitate the loading of wood stock. The material conveyor is also preferably adjustable to accommodate different lengths of wood stock. According to another aspect of the invention, the sawing system has at least first and second power saws on one side of the material conveyor and at least third and fourth power saws on the opposite side of the material conveyor. Each of the four power saws is supported for independent angular movement of its saw blade about a pivot axis that is offset from the plane of the saw blade and parallel to the direction of the movement of the lengths of wood stock on the material conveyor. At least one of the first and second power saws is supported for horizontal movement relative to the material conveyor. At least one of the third and fourth power saws is supported for horizontal movement relative to the material conveyor. The pivot axis of each of the first and third power saws is positioned above the conveying plane of the material conveyor form making top angled cuts in the lengths of wood stock moved on the material conveyor. According to a further aspect of the invention, an algorithm is provided for computing a position of the power saws to make desired angled cuts in the ends of the lengths of wood stock.

Gantry press height adjustment method

An earthworking loader bucket has a specially designed bottom side reinforcement structure which includes a unitary base plate member extending rearwardly from the bottom side front bucket lip and having a front side edge welded to the rear side edge of the lip. Slots are formed in the rear side edge of the base plate and receive bottom end portions of plate-shaped lifting and tilt ears transversely welded to the curved rear side wall of the bucket. Closeout plates are interposed between the bucket rear side wall and rear side portions of the base plate, and the bottom end portions of the ears are welded to the base plate. A spaced plurality of elongated ear extension members longitudinally extend forwardly from the ear member bottom end portions and along adjacent bottom side portions of the base plate and lip, with the extension members being welded to the ear member bottom end portions, the base plate and the lip. The ear extension members function to transfer ear operating loads to bottom side portions of the base plate and the lip, to substantially reinforce the bottom side of the bucket, and also serve as downwardly projecting wear runners to shield bottom side portions of the base plate and lip against abrasion wear.

A gantry press adjustment apparatus for adjusting a vertical orientation of a parallel gantry press with respect to a work surface. The gantry press has a rigid frame with a first side frame portion and a second side frame portion. Each side frame portion has a first and a second generally parallel vertical members. The first and the second side frame portions are spaced sufficiently apart to accept a press roller. The adjustment apparatus has a first and a second planar member which are adapted to receive and support the axle of the roller press. The planar members are slidably mounted along a vertical axis of the frame portions. A first vertical adjustment member is connected to the first side frame portion and to the first planar member. A second vertical adjustment member is connected to the second side frame portion and to the second planar member. A drive is connected with each of the adjustment members to adjust each of member at a substantially equivalent rate and vertical spatial orientation such that the planar members maintain the press roller in a parallel orientation with respect to the work surface.

Parallel adjustable gantry truss plate press

An improved table for use in a truss assembly apparatus is provided. The improved table includes a frame supporting a plurality of panels that define a work surface. According to a first aspect, the plurality of panels are separated by at least one opening extending across the table. Mountings are provided for rotationally mounting a lead screw across the table along the opening between the panels. At least one jig stop carrier is threadedly coupled to the lead screw and movable along the lead screw in the opening between the panels across the table in response to rotation of the lead screw. A jig stop is connected to the jig stop carrier and to project above the work surface of the table. To vertically adjust the height of the jig stop mounted to the jig stop carrier, which is coupled to the lead screw, at least one threaded shank is fixed on each of the mountings. The threaded shank extends through an aperture in the frame of the table to selectively position the mountings on the frame. At least one threaded fastener is provided on each of the threaded shanks for securing the threaded shank to the frame at a selected position along the shank, whereby the mountings are releasably secured at a selected height so that the jig stops are operably associated with the work surface defined by the panels and to accommodate different thicknesses of panels. According to another aspect, adjustable metal end plates are provided to provide an easier baseline alignment for truss construction.
