The present disclosure generally relates to coating material applicators and more specifically, but not by limitation, to an apparatus for applying a coating material such as stain to a surface such as a deck, characterized by a generally planar surface with intentional gaps between elements (e. g. , boards of a deck). In one example, a coating material applicator is provided. The coating material applicator is configured to apply a coating material to a structure having a generally planar surface formed by members having opposed surfaces separated by one or more gaps. The coating material applicator includes a base layer having an applicator surface for applying a coating material to the generally planar surface and a removable implement for applying the coating material to the opposed surfaces.

A hand-held, battery powered liquid applicator having an on-board reservoir. An electric motor drives a piston in the reservoir via a pinion gear member and rack gear. A gear shifter may disengage the pinion gear member from the rack gear. A battery compartment may have a door has recess to enable a user to grasp a dry cell located farthest from the door. The rack gear may have modified profile teeth at the end of travel to allow the pinion gear member to slip when the piston is urged past the end of travel. The piston may have a length substantially equal to a characteristic length of the reservoir. Liquid may be drawn into the reservoir by powered or manual retraction of the piston and liquid may be delivered from the reservoir to an applicator head by powered or manual motion of the piston into the reservoir.

The present disclosure generally relates to systems and devices for spraying fluid materials such as paints, stains, and the like, and more specifically, but not by limitation, to a dual voltage electromagnet motor for an airless fluid sprayer. In one example, a dual-voltage electric airless fluid sprayer is provided and includes a fluid reservoir and a pump configured to receive fluid from the fluid reservoir. An electric motor is operably coupled to the pump and includes a plurality of windings. The plurality of windings include a first winding portion having a first wire gauge and a first number of windings and a second winding portion having a second wire gauge and second number of windings. A power-module receiving portion is configured to receive a power module to couple one of the first or second winding portions to a source of electrical power.

The present disclosure generally relates to fluid spraying devices and systems and more specifically, but not by limitation, to a fluid intake assembly configured to be used with a remote fluid source to supply fluid material from the remote fluid source to a fluid sprayer. In one example, a fluid intake assembly for a fluid sprayer is provided. The assembly includes an inlet tube providing at least a portion of a fluid path between a remote fluid source and the fluid sprayer. The assembly also includes a fluid flow control mechanism configured to allow a flow of fluid material in the fluid path in a first direction and restrict a flow of fluid material in the fluid path in a second, opposite direction. In one example, the fluid flow control mechanism comprises a valve mechanism.

In one example, a fluid intake assembly configured to provide an inlet fluid path for a fluid sprayer is provided. The assembly includes a fluid intake assembly body configured to be removably engaged to a portion of the fluid sprayer by rotating the body with respect to the portion of the fluid sprayer. The assembly also includes a fluid inlet tube configured to be supported by the body and extend from the body within a fluid container to provide fluid flow along the inlet fluid path.
