Abstract: The cartridge spreader system includes a mobile cartridge spreader with a cartridge station configured to engage a cartridge and includes a locking controller for locking the cartridge securely into the cartridge station. The cartridge station includes an activator mechanism for activating and deactivating an engaged cartridge. The cartridge spreader includes an activation controller for activating and deactivating the cartridge. Activation of the cartridge allows the granular product contained in the cartridge to flow out of the container, through a granular chute on the cartridge station, and onto a granular product launcher which launches or impels the granular product over terrain or other surface. When the cartridge is deactivated, the flow path is sealed stopping the flow of granular product. The cartridge itself includes a fitment that engages with the cartridge station. The cartridge fitment includes an appropriately sized metering gate.

Abstract: A spray device for dispensing chemicals is disclosed. The spray device comprises a cartridge defining an interior compartment for containing a liquid product, an applicator having a support body, an extendable wand attached to the support body, a handle at a rear end of the support body, and a pump.

Abstract: A hand holdable pump spray apparatus is disclosed where the pump mechanism is in the hand holdable wand rather than in a spaced apart liquid container. The wand may be held with one hand while a pump handle is extended with the other hand. This creates a pressure differential which allows liquid to flow from the container, passed a check valve and into the wand. After filling, a biased spring provides a force against the liquid creating a higher pressure in the wand than ambient pressure. This closes the check valve. When an operator depresses an actuator, another valve opens allowing the liquid in the wand to be ejected through a nozzle.

Abstract: A hand holdable pump spray system where the pump mechanism is in the hand holdable wand rather than in the liquid container. The wand may be held with one hand while the pump handle is extended with the other hand. This creates a pressure differential which allows liquid to flow from the container into the wand. A biased spring provides force against the liquid so that when a thumb actuated trigger opens the nozzle, the liquid will be ejected. Should all of the liquid not be ejected, there is a liquid return mechanism which opens a check valve and allows the liquid to return to the container through a supply tube connecting the wand and the container.

Abstract: A broadcast spreader constructed from two separate and rotationally molded parts; one molded part integrates the handle and hopper assemblies while the other molded part forms the base assembly that supports the wheels for the spreader. A pair of dovetail-like connection between the molded parts assures a strong and tight fit and proper alignment therebetween. Also provided are a self-aligning bearing for the rotor shaft and a single control for simultaneously operating a deflector plate and an auxiliary dispensing member for the spreader.

Abstract: A large bucket-like utility cart having two pairs of wheels for allowing the cart to be tilted in both forward and backward directions on respective pairs of wheels by means of a collapsible loop handle with an angled crossbar design. A number of such utility carts can be alternately stacked or nested within one another with either the handle extended for use or collapsed or folded to its inoperative position, thus creating a high-density multiple-product module suitable for shipping, storage or display.

Abstract: First and second mold members are fitted one within another and together define a first annular space for forming a discontinuous single thread in a thin-walled housing, as well as a second annular space coaxial and contiguous with the first annular space; the second space defines the thread on the interior wall of the housing in the form of teeth members for receiving a threaded member associated with a linear adjustment device used with an agricultural implement, such as a spreader.

Abstract: A drop spreader having a hopper with a series of materials-dispensing apertures therein supported by a pair of wheels, an upper U-shaped frame pivotally connected to a pair of spaced-apart leg members supported on the hopper for use as a handle for the spreader, the hopper further having molded in place a pair of sleeve members adjacent the rim thereof for receiving the respective leg members, a shutoff bar adjacent the apertures being composed of two different materials, plastic enveloping metal, and further the use of a simple pivotal snap connection between the micrometer device used with the spreader and the control lever for controlling the movement of the shutoff bar.

Abstract: A collapsible drop spreader having a hopper for supporting a wheel axle bearing member, an upper U-shaped frame pivotally connected to a pair of parallel leg members supported on the hopper for use as a handle for the spreader, the hopper further having wheel track alignment guide arrows indexed thereon, a series of material exit apertures extending the length thereof, a two-part rotary agitator bar disposed above the material exit apertures of the hopper, a spring washer for biasing the separate members of the agitator bar apart to effect a sealing relationship with the wheel axle bearing supports, a light weight fiber reinforced shut-off bar disposed adjacent the material exit apertures and rotatable about splines on the wheel axle bearing members, and a flexible cable having one end connected to the rotatably journaled shut-off bar and the other end thereof connected to a control lever located on the upper frame for rotating the shut-off bar from a closed position to an open position with respect to the ma
