The plow can include a moldboard having a movable cutting edge and an adjustable bias trip mechanism having a biasing member preferably in the form of a spring. The adjustable trip mechanism can be arranged with the cutting edge of the moldboard to urge the cutting edge to a plowing position. The spring can be cooperatively arranged with a retainer, a pin for example, at one or more retaining positions to impart a preload biasing force upon the spring that varies according to the retaining position selected. The preload biasing force can act as a trip resistance force which must be overcome before the cutting edge moves. A lever tool can be provided for adjusting the spring.

Abstract: A pressure plate extractor for testing of soils and other porous solids has a pressure chamber defined by pressure chamber sidewalls resting above a pressure chamber base. A drain plate is situated on the pressure chamber base with its bounding edge surrounded by a seal and situated inwardly from the pressure chamber sidewalls, which rest atop the seal. When the pressure chamber sidewalls are urged towards the pressure chamber base, thereby compressing the seal and preventing air from passing between the pressure chamber sidewalls and pressure chamber base, the seal laterally expands to firmly engage the bounding edge of the drain plate, thereby preventing air from passing between the pressure chamber sidewalls and the drain plate. A substantially leak-free pressure chamber results, with low probability of drain plate failure because the pressure chamber sidewalls do not bear directly upon it.

Abstract: A dragline bucket comprises a floor, opposed side walls and a rear wall; a front lip on the floor having adaptors to releasably secure cutting teeth thereto; opposed cheek plates adjacent respective front portions of said side walls; and, hoist rope attachment members located intermediate front and rear portions of the bucket.

Abstract: A chip plow conveyor for conveying abrasive scrap includes an elongated trough having a flat bottom and sides, and a chip-motivating pusher bar. The pusher bar moves longitudinally and floats laterally as the pusher bar reciprocates to move scrap along the trough. Lateral floating of the pusher bar helps overcome binding caused by scrap material wedging between the pusher bar and one of the sides, but wedging still causes the pusher bar to engage the sides with substantial force. The pusher bar includes a bearing component with beveled front corners on a leading end of the pusher bar, with the inclined ramps providing angled engagement with the sides and characteristically providing a longitudinally-angled corner surface arrangement that cannot be sharpened into a knife-simulating edge even after substantial wear against the flat bottom and the sides of the trough.

Abstract: A bucket assembly is provided with a kit that includes a base plate for permanent connection to a lower part of the bucket, and sacrificial, impermanent replaceable wear edge segments for the forward lip and corner leading edges of an excavator or loader bucket. These segments form a set of “bolt on” cast wear members and wing wear segments. The base plate and wear plates are drilled and machined to accommodate the precision fitting bolting on of the replaceable lips and cast wing segments. The cast lip segments are of both left and right hand configurations and come in a variety of widths that, in combination, may tend to fit a large number of different commercially available bucket sizes. The lip top and bottom faces are shaped in a profile that may tend to result in relatively uniform wear and a reduction in friction when digging into various materials.
