Filter adapter head

A filter device for use in a residential water supply system, or the like. The device includes a container having an enclosed cavity, and includes a filter unit disposed in the cavity. The device includes a two-stage filter having a first radial flow filter subassembly and a second axial flow filter subassembly.

Radial and axial flow stage filter device

A filter device for use in a domestic or office water supply system is provided. The device includes a container having an enclosed cavity, and includes a filter unit disposed in the cavity. The device is a two-stage device having a first radial flow filter subassembly and a second axial flow filter subassembly. The radial flow subassembly includes a radially inner perforated tube, a carbon block cylinder over the tube, prefilter cylinders over the carbon block cylinder, and a screen-like wrap layer over the radially outer second prefilter cylinder. The axial flow subassembly has a plurality of axial filter fiber tubes which have a support header wall. The header wall is mounted in a cup-shaped member. The cup-shaped member has a plurality of outlet passage slots at the closed end thereof and supports the header wall at the other end thereof.

Combined water filter and stand therefor or similar article

A filter apparatus is used to filter tap water and to automatically fill two containers. This apparatus includes a filter subassembly, a housing subassembly, a water control subassembly, and first and second containers. The water control subassembly includes a center see-saw chute receiving filtered water from a supply line from the filter subassembly, and includes a left pivoted chute and a right pivoted chute, each receiving a selectively directed water stream from the center chute. Each pivoted chute has a float at one end thereof, in contact with the water in its respective container when about full. An upward force from its container water pivots each left and right chute, when the container is about full, causing the respective water stream to be redirected in the opposite direction along its chute to a reservoir and drain line. In a preferred embodiment, first chute has a cam surface, which bears against a surface on the center chute, thereby pivoting the center chute, and redirecting the water stream to the right chute.

A filtering device includes a head intended to be permanently installed in a fluid dispensing machine and a disposable canister therefor. A central chamber is formed in the head which chamber is in communication with an inlet port and an outlet port for receiving an unfiltered liquid and supplying a filtered liquid, respectively. The disposable canister has a flask shaped main body with a flat top and a neck of substantially uniform diameter on the top. The neck fits in the central chamber. A tube extending through the neck defines an annular clearance between the tube and the interior of the neck which annular clearance is in fluid communication with the inlet port. The opening into the tube located at the top of the neck is in fluid communication with the outlet port in the head. A pair of tab receptacle on the head and a complementary pair of tabs on the canister are engageable with one another by 1/4 rotation of the canister to lock the canister to the head.
