Abstract: A motorcycle trailer with two independently suspended wheels has a frame comprised of front and rear U-shaped members. The legs of the rear one project forward between the rearwardly projecting legs of the front one and are secured at their front ends to the bight portion of the front one. To the rear end of each leg of the front member is fixed an upright support having at its upper end a pivotal connection to the top of a vertical element of an L-shaped wheel carrying arm. A horizontal element of that arm projects rearward from the bottom of the vertical element, in laterally inwardly offset relation to it. A wheel axle fixed to the rear of the horizontal element projects laterally outwardly from it to dispose the wheel in rearward alignment with the pivotal connection. A coiled tension spring and a cylinder-type shock damper are connected between the vertical element and the leg of the front member.

Abstract: The sealing assembly includes a relatively soft rubber, tubular sleeve having an axial length sufficient to span the joint between hollow members, such as the corbel joint between a manhole frame and a manhole casing, and a sealing portion in each of the opposite ends. The outer surface of each sealing portion is compressed radially outwardly in sealing engagement with the interior walls of the manhole frame and the manhole casing by a generally circular hoop which fits into a groove provided in the inside surface of the sleeve. Each hoop has circumferentially movable, end portions and a radially inwardly extending bracket mounted on each end portion at circumferentially spaced locations. These brackets are adjustably pulled toward each other, to increase the circumference of the hoop, by tightening a nut threaded onto the outer end of a bolt connecting the brackets together.

Abstract: Palletizing apparatus for bags includes a bag flattener and vibrator, a bag pattern forming diverter, a row forming station, a full layer forming station, a pallet elevator and a pallet magazine. A programmable control for the diverter provides automatic sequencing of the diverter for orienting the bags in left or right lanes on a diverter conveyor to form a selected bag pattern. Either left or right lane can be provided with a turnpost which has a controlled deflector which either exposes the turnpost for rotating the bags 90 degrees or guides bags past the turnpost depending on the selected pattern. The programmable control enables automatic control of the diverter to provide successive layers of the same pattern but with a different orientation and also afford formation of many different bag patterns. The final layer forming station has movable guides to square the patterned layers before deposition on the pallet in the pallet elevator and guide the layer as it is deposited on the pallet.
