Abstract: A horizontally extending body or base member includes a forward portion and a rearward portion and has downwardly projecting teeth for engaging a wire grid mounted on a bed or floor. The forward portion of the base member supports a wheel engaging head member for relative horizontal movement between extended and retracted positions, and compression springs bias the head member to its extended position. A lock member is supported by the rearward portion of the base member for pivotal movement between released and locked positions and also has downwardly projecting teeth for engaging the wire grid. The head member carries a wheel engaging extension member for pivotal movement between retracted and extended positions. A side paddle member is also carried by the head member to resist lateral movement of the wheel, and preferably all of the members are each molded of a liquid thermoset plastics material.

Abstract: An over-molded product, such as a container, and a method of manufacture. The product is primarily used for enclosing hazardous materials and is formed by utilizing a thermosetting plastic material in a reaction injection molding process at low temperature and pressure to envelop adjacent portions of two or more components to form the desired product. This provides a mechanical interface but avoids a chemical reaction which would degrade the components.

Abstract: A pivot plate assembly for supporting vehicles over the articulation between pivotably interconnected railway car units, and allowing rolling transport of vehicles from one railway car unit to the next. Platforms are pivotably attached to respective railway car units adjacent their interconnected ends. A vehicle has its front end portion secured to one of the pivotal platforms and its rear end portion secured to the other platform while the platforms are oriented collinearly with respect to one another. The vehicle thereby maintains the pivotal platforms collinear with one another as the railway car units pivot with respect to one another. Accordingly, the pivotal platforms remain substantially stationary with respect to the vehicle supported thereon throughout pivotal movement of the railway car units to stably support the vehicle straddling the articulation between pivotably interconnected railway car units during transport.

Abstract: A pallet retainer for securing a load on a pallet within a cargo container is monolithic and has upper and lower arms. The arms are placed under and over a transverse member of the pallet and the retainer is secured to the floor of the cargo container by various means to prevent forward and aft shifting. The upper arms may be bifurcated into two transversely spaced segments to retain the vertical members of the pallet and prevent transverse shifting.

Abstract: The portable washer cutter of this invention comprises a pair of enclosures adapted to be interconnected and operative to rotate to progressively close the two enclosures together. A cutting knife edge secured in one enclosure progressively engages with each rotation a flat washer blank supported in the other enclosure to produce a desired central cut-out from the washer blank.

Abstract: A hand tool for cutting a textile cot from an associated mandrel, method of making such tool, and method of utilizing the tool and removing such a cot from the mandrel are provided wherein such tool is in the form of a pliers-like instrument having a special cutting blade.

Abstract: A tool for cutting a textile cot from an associated mandrel is provided wherein such tool is particularly adapted to be attached to one of a cooperating pair of machine components which are relatively movable toward and away from each other and a mandrel with a cot to be cut supported on the other component whereupon the cot is cut axially along its length upon relatively moving the components toward each other.

Abstract: A clamp for reinforced flexible hose made of a continuous member which is attached to the reinforcement at one or both ends of the hose. Application of force to the clamp expands the hose end to permit insertion or removal of an adjacent member, such as a coupling or fitting.

Abstract: A vacuum cleaner hose assembly and method of making same are provided wherein such assembly comprises, an elongated vacuum hose having a hose end, a plurality of electrical conductors extending along the vacuum hose with each conductor having an end portion disposed immediately adjacent the hose end, a plurality of electrical connectors each fixed to an associated end portion of an associated conductor, a flexible hose fitting fixed to the hose end with the fitting having a plurality of the electrical connectors embedded therein which are movable with flexing movements of the fitting, a rigid hose adapter operatively connected to the fitting, an electrical device carried by the adapter and connected to the embedded connectors with the device having precisely aligned integral electrical connectors, and cooperating portions on the adapter and electrical device self positioning the electrical device relative to the adapter with the precisely aligned electrical connectors readily accessible for easy mating with c
