The insulation member has a one piece construction comprising an upwardly convex center portion which mates with the concave base of the inner tank, a peripheral ring which spans the insulation gap and an annular channel between the center portion and the peripheral ring which seats the inner tank of the water heater.

Abstract: A method provides a mold for producing a product where the product includes material over an undercut opening in the product. The mold comprises first and second mold sections which open and close relative to one another and the first mold section in itself includes mold parts which open and close relative to one another. The mold is arranged such that when the first and second mold sections are closed, the mold parts of the first mold section are also closed to define a mold cavity between the mold sections and further including a cavity region for forming the material over the undercut opening between the mold parts of the first mold section. The mold then opens in a manner in which the first and second mold sections are opened which then allows the mold parts of the first mold section to open for releasing the product from the mold.

Abstract: The present invention relates to a fascia angle adapter for an eavestroughing system wherein the fascia angle adapter allows for supporting of an eavestrough hanger or other support fitting at different angles relative to a fascia board. The adapter is placed intermediate the hanger and the fascia board. The adapter has a base member having a fascia engaging surface, a top port for securing of the adapter to a fascia board, and an eccentric cam supported by the base member and movable with respect thereto whereby the cam can be moved to various positions such that the exterior surface of the cam is spaced a different distance from the fascia engaging surface. The cam member is preferably rotatably supported within the base member and has a number of planar surfaces about the periphery of the cam for defining, in cooperation with the base member, predetermined angles for known angled fascia.

Abstract: The eavestroughing system uses hidden hooks in combination with a particular evestrough which allows the effective placement of a leaf screen within the eavestroughing system. The leaf screen is engaged either side thereof in a simple manner, allowing convenient ease of insertion of the screen within the eavestroughing system and in a predetermined orientation. The eavestrough section cooperates with the hanger to provide support for the screen adjacent a forward edge of the screen and also serves to hide the forward edge of the screen within the eavestrough section. The preferred orientation of the screen advantageously is disposed at a downwardly extending angle to the forward edge of the eavestrough to encourage the movement of debris across the screen towards the forward edge where it can easily be removed by the end user and/or removed by natural causes. This natural tendency to move the debris across the screen reduces accumulation of debris on the screen.

Abstract: An eavestrough fitting according to the present invention comprises a moulded plastic member having an improved gasket secured thereto. The gasket has at least two ribs extending across the member and up the sides thereof with the ribs sized to form a seal with an appropriately shaped eavestrough inserted within the fitting. The moulded plastic member has a generally flat base connected to outwardly angled sidewalls which terminate in a short vertical section. The gasket conforms to the shape of the moulded plastic member and includes a raised land interior to the ribs. This raised land limits the extent of deformation of the ribs while providing a resilient base for supporting the eavestrough section within the fitting. The raised land allows the eavestrough section interior to the ribs to be in contact with the land and the lower surface of the eavestrough such that grit and other debris has less of a tendency to become lodged beneath the eavestrough section.

Abstract: An eavestrough fitting according to the present invention comprises a body portion of a shape generally corresponding to the eavestrough to be axially received therein, with a fitting on the interior surface including an abutment member positioned to limit the extent to which an eavestrough is axially inserted within the fitting. Retaining tabs extend above and project outwardly from the abutment member and define a slot like opening between the retaining tabs and interior surface of the fitting into which an end portion of the eavestrough is inserted and retained. A sealing arrangement is moulded to the fitting on the interior surface of the fitting in front of the retaining tabs and forms an effective seal between the lower surface of the eavestrough and the eavestrough fitting. This fitting allows for an effective method of joining lengths of eavestrough, whether they be symmetrical or nonsymmetrical, and positively retain the eavestrough within the fitting.

Abstract: The present invention relates to an eavestrough fitting having a molded plastic member with a gasket secured thereto having a unique configuration. The gasket has at least two ribs extending across the molded plastic member and up the sides thereof, with these ribs being sized to form a seal with an appropriately shaped eavestrough inserted within the fitting. The eavestrough is inserted into the fitting and the gasket includes resilient aligning members urging the sidewalls of the inserted eavestrough towards the center whereby the base of the eavestrough is more positively urged into sealing contact with the ribs across the base of the molded plastic member.

Abstract: An eavestrough system comprises a particular eavestrough section having inwardly directed locking flanges adjacent opposed upper edges thereof. This eavestrough section is designed to cooperate with a hidden hook having a cored base portion which cooperates with a cantilevered arm whick supports the eavestrough at the free end thereof. A downwardly opening locking slot is provided at the junction of the arm and base.

Abstract: The present invention relates to an end piece for a water heater dip tube which converts the dip tube from primarily a water feed only, to a combination water feed and turbulator. The end piece comprises an end face at right angles to the water flow through the dip tube with openings radially around the end face and the openings being symmetrically positioned for balanced pressure water flow to all sides of the end piece thereby eliminating directional torque on the dip tube itself.

Abstract: The present invention relates to fabricated metal toilet stall panels comprising opposed panel sheets, each having flanged edges which cooperate to define an essentially hollow core. The panels at the flanged edges include an inwardly directed sealing flange in abutting opposed relation with the like sealing flange of the opposed panel sheet. The metal panels are at least primarily secured to each other by an adhesive seal between the sealing flanges. The method of the present application comprises forming of the metal panels, including the flanged edges with the inwardly directed sealing flange, placing opposed panels in abutting contact such that the sealing flanges generally engage, applying an adhesive between the sealing flanges, and maintaining the particular relationship of the panel sheets until the adhesive has cured to an extend sufficient to maintain the engagement of the panels.

Abstract: The present invention provides a pump arrangement formed with a plastic pump housing and a motor housing secured to one another. A heat transfer member extends between the housings for picking up heat generated in the pump chamber of the plastic pump housing and transferring the heat for dissipation internally of the motor housing.
