Abstract: A collapsible broadcast spreader having a lower frame for supporting a wheel axle, an upper frame pivotally connected to the lower frame for use as a handle for the spreader when the upper frame and lower frame are in an extended position, a hopper also supported by the lower frame and having a materials exit aperture in the hopper, a slide integral with a bottom wall of the hopper, a shut-off plate disposed within the slide, a flexible cable having one end pivotally connected to the shut-off plate and the other end thereof connected to a control lever located on the upper frame for moving the shut-off plate from a closed position to an open position with respect to the aperture, wherein the control cable and the shut-off plate are in-line.

Abstract: According to one embodiment of the present invention there is provided a two-part shipping and display carton for use with a stacked array of portable wheeled spreaders, each spreader having a hopper, a pair of wheels disposed below the hopper, a lower frame supporting the hopper, and an upper frame pivoted to the lower frame and being pivoted into a collapsed state so that the upper frame lies generally adjacent the lower frame. A bottom portion of the carton receives the stacked array of spreaders, while a top portion of the carton having a similar cross-sectional shape as the bottom portion and a height that is slightly higher than the height of the stacked array of spreaders fits within the bottom portion so that the outside surfaces of its walls contact the inside surfaces of the walls of the bottom portion when the top portion is lowered into the bottom portion.

Abstract: A rotatable locking device composed of a flexible plastic material is disposed adjacent the end portions of each pair of legs for barricade structure for streets and highways. The locking device can be rotated into an operating position where it bears against the tips of the end portions of the legs when extended and so locks them into place to thereby keep the legs extended during harsh weather conditions and when the barricade is subjected to repeated gusts of winds from passing trucks. When the barricade is suddenly impacted, however, the end portions of the leg members will spring free from the locking devices owing to elastic deformation or "forgiveness" of the flexible plastic material that comprises both locks and legs to thereby allow the leg members of the barricade to fold or collapse to a safe position.

Abstract: A hand cart or wheelbarrow is provided with a tub member having slanted walls, one with respect to another, together with suitably designed auxiliary members, such as a handle, wheels, axle and hardware. At the factory site the auxiliary members and hardware are placed within the tub and enveloped as a unit with a packaging material so that the resultant package is of the same general shape and configuration as the tub and contains all the elements of the complete product. In this way each package can be nested in another like package, and a plurality of such packages, so nested together, can form a compact shipping unit, storage unit or sales unit that affords maximum protection to each product and that virtually eliminates wasted space between the stacked products.

Abstract: A multiple dilution ratio aspirator sprayer adapted to be connected to a hose for mixing a liquid with pressurized water from the hose and providing a spray of the mixture comprises a container for housing the liquid to be mixed with the water; a mixing head having a nozzle at one end thereof and a garden hose attachment device at the other end thereof; a mixing chamber within the mixing head; a hose for communicating the liquid from the container to the mixing head; a disk having a plurality of apertures therein rotatably mounted in the mixing head to control flow from the container to the mixing chamber; a flow tube communicates liquid in the container to the inlet to mixing chamber through a selected aperture in the disk so that the liquid is diluted with pressurized water at a dilution ratio determined by the size of the aperture aligned with the tube and the mixing chamber; and a cleaning orifice is positioned circumferentially from the mixing chamber so that each of the plurality of apertures may be sel

Abstract: What is provided is a utility cart of a one-piece rectilinear design supported by two coaxial wheels, the cart having a lipped or beveled portion at the top of its sidewalls and a U-shaped handle pivoted through respective lipped portions at one end of the cart so that the handle may be easily swung down from an operable position to a folded position within the confines of the overall dimension of the cart. When the handle is in its operable position, the free ends thereof are easily secured under the respective lipped portions to thereby give the entire structure the strength and leverage required for proper load-bearing use.

Abstract: A lightweight vertical panel barricade for use on streets and highways in which a first vertical panel is supported and rigidly locked into place by the clamping effect of respective ends of leg support members acting against a wall support of a housing structure disposed at each end of the panel member. The leg support members are rectangular in cross-section and are virtually gripped on three side faces thereof by the housing structures in which they are pivoted, both in their extended, panel support position and their closed, storage position. A second panel member depending from and coplanar with the first panel member is surrounded by the leg members and provides a doubling of the reflective surface of the barricade.
