Abstract: An applicator comprises a housing having a liquid input, a pump, a motor, and a power source; a trigger for providing selective control over the pump; a wand hingedly connected to the housing; and a nozzle coupled to the wand for discharging liquid from the applicator. The nozzle and the liquid input are in fluid communication via the pump and various conduits of the applicator.

Abstract: A ready-to-use sprayer comprises a container defining an interior compartment for containing a liquid product, a housing having a main chamber and a grip portion, a nozzle in selective fluid communication with the outlet of the fluid chamber, and a pivot switch on the exterior of the housing for selecting a fluid flow condition for the main chamber.

Abstract: A spraying device is provided that includes a cartridge containing a first fluid, the cartridge being removably connected to a sprayer body. The cartridge is oriented such that gravity exerts a downward force on the first fluid. The sprayer body includes a conduit for receiving a second fluid. A valve is coupled to the conduit. The valve allows the second fluid to flow through the valve, thus creating a Venturi vacuum that draws the first fluid out of the cartridge and into the valve to enable the first and second fluids to mix and form an outlet stream. An orifice meters a predetermined amount of the first fluid into the valve to achieve a predetermined ratio of the first fluid to the second fluid. The outlet stream is then dispensed from a spray nozzle.

Abstract: An improved collapsible spreader with a spread rate selection mechanism including a knob and a rotatable cup-shaped structure. The cup-shaped structure includes an elongated setting tab and a thirty-six step edge corresponding to thirty-six spread rate settings on the knob. Operatively engaged with the cup-shaped structure is an abutment tab that is part of a closure structure for blocking and selectively unblocking a hopper opening. The tab engages the setting tab to define the adjustable length of the closure structure. Thereafter, abutment rate selection is a function of the rotatable position of the cup-shaped structure. Engagement of the abutment tab and a step defines the size of the hopper opening and thus the amount of product released from the hopper during operation. The spreader also includes a dual spring arrangement to bias the closure structure to a closed position and to prevent breakage. The disclosed spreader also features a one piece wheel to reduce parts and assembly costs.

Abstract: A hand held spreader having the bottom-face of the hopper portion at an angle with respect of the horizontal and having the handle for holding the device disposed directly below the hopper and so directly below the weight of the hopper; the handle is angled so as to afford an in-line action between the trigger of the handle and the slide of a dispensing mechanism, thus avoiding any requirement or a linkage between the trigger and the slide mechanism. Also the gear-box portion of the device is of a simple clam-shell design that allows the rotary drive shaft of the device to be removably supported on opposite sides of its load bearing section by means of bearing supports on both sides of at least one of the gears. The supports are part of the separate halves of the housing itself, thus avoiding the need for additional or separate bearing structures.

Abstract: The invention provides an easily assembled connector for handle sections of a wheeled appliance in which the connector is formed from a plastic having an agressive memory for enabling a pair of opposed tab members thereon formed from the same material to cooperate with respective apertures in the handle members to be joined or connected. The handle members are slip-fitted the one onto the other with the connector occupying a reinforcing position on the inside surface of the end of the innermost handle member in one embodiment and, according to another embodiment in which the connector housing comprises two half portions, joins the handle members in an abutting relationship.
