  • Patent number: 11612909
    Abstract: A method of texturing a wall or ceiling with non-acoustical joint compound by providing a collapsible bag having an opening at its top and is adapted to contain non-acoustical joint compound for forming a textured coating on the wall or ceiling and providing a spray nozzle having a low pressure input port, a joint compound suction port attached to the opening at the top of the collapsible bag, and an output port for spraying the non-acoustical joint compound. A low pressure stream of air from an air gun attached to the low pressure input port urges a small quantity of the non-acoustical joint compound to be sprayed out of the spray nozzle when the bottom of the collapsible disposable bag is raised above its top to either allow or force the joint compound to flow into the suction port and into the interior of the spray nozzle.

  • Publication number: 20150069147
    Abstract: A paint spray gun for use in association with a HVLP turbine blower and an attachable paint container divides input air flow into two horizontally adjacent channels. Air flow through one channel remains open whereas air flow through the second channel may be varied by a side air controller such that when air flow is cut off from the second channel, the paint mixture is sprayed in a substantially circular shape whereas when air flows through the second channel the paint mixture is sprayed in a substantially fan shape. In another embodiment, a rotatable nipple is positioned to redirect some air flow from the channels to drive paint from the paint container.

On the opposite end of the hollow pole handle is a trigger. When the trigger is activated, an internal trigger stick is moved down through the hollow pole, thereby causing a “C” shaped piece to move upward. This upward movement pushes on a hard flat disk. The movement of the hard flat disk causes pliable cap center to move. The gravity flow of liquid herbicide from a liquid herbicide container causes the liquid herbicide to move through a tube and nozzle assembly. The adjustable width protective shield over the nozzle prevents overspray and accidental contact of the liquid herbicide on healthy desired vegetation.

  • Patent number: 7823806
    Abstract: A connector part (3) for connecting a material supply device (10) to a spray gun (20) that includes a hollow cylindrical connection piece (5); a threaded wedge element (8) with a lower starting point (8a) and an upper end (8b) running around the outer circumference of connection piece (5) and serving to produce a threaded wedge connection to a counter-element (15) arranged on gun base (19) of spray gun (20); and a stop element (14) that forms a limit stop during the production of the threaded wedge connection. In order to prevent the counter-element on the spray gun from digging into the soft connection pipe made of plastic and removing plastic chips there, it is provided in the connector part according to the invention that stop element (14) is arranged at a distance in the circumferential direction from upper end (8b) of threaded wedge element (8), whereby a gap (11) is formed between stop element (14) and upper end (8b) of the threaded wedge element.

  • Patent number: 7819341
    Abstract: The invention relates to a gravity flow reservoir for a paint spraying gun having a container and a cover, which can be placed thereon and which has a connecting part in order to place the gravity flow reservoir onto the paint spraying gun or onto an adapter. Prior art reservoirs require a separate pointed tool, which serves to make a vent hole, is often unavailable and can lead to operating errors. The aim of the invention is to provide a paint reservoir system that enables a simple, rapid and uncomplicated insertion of a vent hole into the container wall of the gravity flow reservoir while preventing shavings or plastic parts from entering the gravity flow reservoir. To this end, a delimited area is provided in the wall of the container and can be penetrated by the pointed tool in order to make a vent hole.

  • Patent number: 7815130
    Abstract: A paint reservoir has a fluid outlet 115 connectable to a spray gun 101 and a fluid inlet 131 provided with a removable screw cap 132 whereby the fluid inlet 131 is directly accessible for introducing paint to the reservoir while attached to the spray gun 101. The fluid outlet 115 and fluid inlet 131 may both be provided in an end wall of the reservoir with outlet 115 located on the longitudinal axis of the reservoir or offset to allow the size of the fluid inlet 131 to be increased for easier filling of the reservoir. The outlet 115 can be aligned with the longitudinal axis of the reservoir or it can be inclined relative to the longitudinal axis to provide greater clearance for access to the fluid inlet 131 when the reservoir is attached to the spray gun 101. In an alternative arrangement, the fluid outlet is provided in an end wall of the reservoir and the fluid inlet is provided in a sidewall of the reservoir.

  • Patent number: 7798425
    Abstract: A spray gun (1) has a fluid reservoir (11) which contains a removable liner (13). The liner (13), which may be thermo/vacuum-formed from a plastic material, is a close fit within the interior of the reservoir and collapses as fluid is withdrawn from within the liner during operation of the gun. Preferably, the liner has a comparatively-rigid base and is capable of standing, unsupported, outside the reservoir. The side walls of the liner are preferably thin in comparison to the base and can be collapsed for disposal of the liner. The reservoir (11) has a removable lid (15) and is capable of standing, inverted, on its own so that it can be filled with fluid. The lid (15) also functions to secure the liner (13) in the reservoir and, at the end of a spraying operation, the lid (15) and the liner (13) are removed together from the reservoir (11) and discarded, thereby simplifying the cleaning of the spray gun.
