Abstract: A portable shaker frame that is particularly adapted for separating irregularly-shaped wood shavings used in animal stalls as bedding materials from manure contained in the bedding material. The wood shavings are recovered for reuse and the manure is separated therefrom for disposal. The shaker frame is inclined and is suspended on springs carried on a carriage having wheels to permit it to be moved from place to place. The springs permit the shaker frame to vibrate relative to the carriage frame. The shaker frame includes a number of longitudinally extending, substantially parallel steel rods that are spaced from each to enable the irregularly-shaped wood shavings to pass therethrough while the manure slides downwardly along the rods and into a collection container for disposal. A vibratory motor is positioned on an end panel of the shaker frame for imparting vibratory motion to the rods carried by the shaker frame.

Abstract: Soil sampling apparatus for forming and containing a core sample of a predetermined depth of soil into which the soil sampling apparatus is driven. A pair of cooperable, core-defining core tube members are carried on a guide rod and are individually and sequentially driven into the soil to be sampled. The core tube members include angularly positioned panels for increased torsional rigidity, and the apparatus includes a cam and follower arrangement for permitting automatic circumferential orientation of one core tube member relative to the other core tube member before interengagement of the core tube members to define a complete core tube. The core tube members are each pointed at their lower ends to more easily penetrate the soil, and one core tube member includes a pivotable soil sample gate to retain the soil sample within the core tube as the core tube is withdrawn from the soil.

Abstract: Soil sampling apparatus for forming and containing a core sample of a predetermined depth of soil into which the soil sampling apparatus is driven. A pair of cooperable, core-defining core tube members are carried on a guide rod and are sequentially driven into the soil to be sampled. The core tube members include angularly positioned panels for increased torsional rigidity, and the apparatus includes structure for permitting remote axial orientation of one core tube member relative to the other core tube member. The core tube members are each pointed at their lower ends to more easily penetrate the soil, and they are individually and sequentially driven into the soil to be sampled. One core tube member includes a pivotable soil sample gate to retain the soil sample within the core tube as the core tube is withdrawn from the soil.

Abstract: A remotely operable shackle particularly adapted for connecting a mooring line to a mooring loop. The shackle may be detachably carried by a boat hook and is remotely operable to connect and disconnect the shackle from a mooring loop.

Abstract: A portable earth core sampling machine has a principal supporting structure which is an upstanding hydraulic cylinder sub-assembly, comprising, a hydraulic cylinder serving as the principal vertical stationary body, a piston rod serving as the principal vertical extendable body, an elongated guide member secured to the exterior of the hydraulic cylinder, a sleeve slidable up and down the hydraulic cylinder along the elongated guide member, force transmitting tie rods secured between the extendable end of the piston rod and the sleeve, and a base, removably secured to the bottom of the hydraulic cylinder with radially extending legs terminating in receiving portions each holding a removable earth penetrating stake, and equipped to receive other subassemblies to complete the overall portable earth core sampling machine, such as: a hydraulic driving power unit subassembly mounted on the sleeve comprising, a driving hydraulic motor to rotate a hollow core digging auger; a transverse header box having a sheave mou
