  • Patent number: 10281189
    Abstract: A combination light and pressure relief vent (10) is disclosed which includes a housing (11), a valve assembly (12), and a light assembly (13). The housing include a valve body (16), port tube (17), and an outside louver (18). The valve body has a low pressure intake port (25), a high pressure intake port (26), and a low pressure exhaust port (27). The valve assembly includes a low pressure intake valve (40), a high pressure intake valve (42), and a low pressure exhaust valve (44). The light assembly includes a heat sink casing (51) which partially defines a heat chamber (52). The casing has a front wall (55) to which is mounted an LED module (57). A lens cover (61) is coupled to the front surface of the casing. Heat generated by the LED module is transferred through the casing to the heat chamber to warm the valve assembly.

  • Publication number: 20160083993
    Abstract: There is disclosed a hinge (10) having a cartridge (12) with a round interior channel (16), a mounting flange (20) with a mounting hole (24) therein, a bushing (28), a pivot pin (33) having a square shoulder section (43) and a round shaft (44), a cam follower (49), a cam (50), a compression spring (51) and a spring retainer (52). The cam follower has a square mounting hole (55) which fits within the square shoulder section. The cam includes central hole (58) configured to receive the pivot pin shaft. The cam includes elongated guides (61). A cabinet mounting bracket (72) is coupled to the pivot pin. The hinge is assembled by coupling the cam follower onto the pivot pin prior to placing the combination into the cartridge with the pivot pin square shoulder section received within the cam follower square mounting hole to prevent relative rotation therebetween.
