Abstract: A spraying device includes a housing that has a spraying unit and a trigger assembly. The spraying unit is a removable insert within the housing. The spraying unit includes an air chamber that is coupled to a liquid tank. A front end portion of the air chamber has a nozzle. The air chamber receives a liquid tube that opens in the nozzle. The liquid tube receives a needle and the needle and the liquid tube are coaxial with each other. The trigger assembly controls the flow of liquid through the liquid tube by positioning a tapered front end of the needle. The trigger assembly includes a trigger that has a first position and a second position. In the first position, the opening of the liquid tube is closed by the needle. In a second position, the liquid tube is opened to discharge a liquid from an opening of the liquid tube.

Abstract: A nozzle for use with a sprayer, such as a spray gun for a pressure washer or a garden hose system, includes a body, which has an inlet for receiving a pressurized flow of water. The nozzle further includes first and second outlets, and first and second passages. The first and second outlets are formed in an end of the body. The first passage extends between the inlet and the first outlet, and the second passage extends between the inlet and the second outlet. The first and second passages are substantially straight and parallel to one another. During operation of the nozzle, the pressurized flow of water from the inlet is split, passes through the first and second passages, and exits the body from the first and second outlets.

Abstract: A foam dispenser includes a refill unit and a dispenser housing. The refill unit carries foamable liquid and provides a liquid pump portion actuated to advance foamable liquid through the dispenser. The dispenser housing provides an air pump portion actuated to advance air through the dispenser. The air pump portion communicates with the liquid pump portion when the refill unit is properly placed in the housing. The liquid pump portion includes a piston housing that reciprocally receives a piston assembly to define a collapsible liquid chamber. Similarly, the air pump portion includes a piston housing that reciprocally receives a piston assembly to define a collapsible air chamber. Upon actuation of the dispenser, both the liquid chamber and the air chamber collapse and thereby feed air and liquid to an extrusion chamber, and extrude the mixture of air and liquid therein through a premix chamber and at least one mesh screen.

Abstract: The present invention is a vibratory pumping apparatus that increases the ease and effectiveness of use of the apparatus. More specifically, the apparatus includes an adapter engageable with a conventional motive member, such as an electric drill, in order to enable the apparatus convert the rotational motion of the motive member into oscillatory motion for the pump, such that the pump can be operated using any number of different motive members. In addition, the mechanism within the apparatus is formed of a pair of piston-like members that operate in conjunction with one another to increase the pressure at which the fluid pumped by the mechanism is dispensed from the apparatus.

Abstract: An air brush includes a brush member with a head portion at an end and a nozzle on the head portion. A nozzle cover is detachably bonded to the nozzle. The nozzle cover has a first attracting portion, and the nozzle has a second attracting portion associated with the first attracting portion. The first attracting portion and the second attracting portion are attracted together by a magnetic force to bond the nozzle cover to the nozzle.

Abstract: Methods and apparatus are provided for dispensing chemical material, and in particular, granular, agricultural material, from a moving device driven over terrain to be treated with the material. A metering system for dispersing the material includes on apertured metering disk positioned above a rotatable impeller. The apertured disk meters material from a product container, by gravity feed, onto the impeller below at a rate proportional to the linear speed at which the apparatus is driven to dispense material at a uniform density over the terrain. The metering disk is a component of a product container which is removably mounted to the device. The impeller rotates at a constant speed to disperse the deposited material at a uniform distance from the apparatus, and the position on which the material is deposited on the impeller is adjustable.

Abstract: An air brush apparatus that is made up of a head assembly, a shell assembly, an air valve assembly for controlling the compressed air which is fed into the apparatus, a handle assembly, a lever assembly, and a paint regulating needle, with a distal end and a proximal end, being movably inserted into the handle assembly and through the air valve assembly and into the head assembly. The paint regulating needle can be cleaned by simply twisting the handle assembly. The apparatus also is designed with a more comfortable and ergonomic lever handle assembly.

Abstract: An air brush. The brush includes an adjusting function, in which without bringing about an increase in manufacturing cost, the adjusting function for arbitrarily adjusting a retreating position of a needle is provided and blowing-off of a certain amount of coating material can be easily performed. The air brush is constructed by detachably and threadedly connecting a cap member to a rear section of an air brush body in such a manner that the cap member covers an adjusting screw and a rear portion of the needle. An abutting portion is provided in an interior of the cap member and the chuck adjusting screw is adapted to be abutted against the abutting portion upon retreating of the chuck adjusting screw retreated by the operation of an operating lever.

Abstract: An air brush is shown and described including a replaceable, rotatable, nozzle head including a media port and a needle arrangement. Media contamination of the air brush is limited to the removable nozzle head, thereby making the air brush body free of media contamination. By rotatable mounting of the nozzle head, a variety of media sources are made available, ranging from gravity fed devices such as media top and side cups to suction fed devices such as media jars. The trigger arrangement of the present invention presents an actuator shaft movable longitudinally in response to trigger movement for engagement of the needle of the nozzle head. Mechanical coupling between the air brush body and nozzle head is limited to structural coupling for mounting the nozzle head and an abutment relationship between the actuator shaft and the needle. This allows rotational freedom of movement for the nozzle head relative to the body, and also ease of dismounting by simply separating the nozzle head from the air brush body.

Abstract: The specification and drawings disclose an apparatus for dispensing a fine dispersion of grease into the interior of baking pans. The disclosed apparatus comprises a continuous screen belt which moves above a conveyor on which the pans are traveling. Above one run of the belt is an air chamber from which high-velocity, short-duration air jets are directed downwardly through the screen. The air jets are laid out in a pattern generally corresponding to the shape of the interior of the baking pans. Additionally, a roller and hopper assembly is provided to apply a coating of grease to the mesh so that the air passing therethrough causes the grease to be dispersed into the pans.
