Patent number: 6611967Abstract: A dump bucket toilet that enables the construction of a toilet that has a low profile and that avoids splashing of water. A barrier (90) lies over much of the first side portion of the bucket to prevent the very rapid discharge of water from the bucket into the surrounding tank when the bucket is tipped, but to instead allow water to be discharged through an opening (92) of moderate size. This avoids splashing and keeps the bucket in it dump position for a few seconds to avoid the bucket scooping up water at the bottom of the tank. A return wall (120) at the bottom of the middle of the tank retains water at a second side portion of the tipped bucket to urge the bucket to tilt back to the filled position.Type: GrantFiled: June 6, 2002Date of Patent: September 2, 2003Assignee: Flapperless, Inc.Inventors: Arnold Hennessy, Philip Hennessy, Myron Ament

Patent number: 5887293Abstract: A dump bucket apparatus is described for use in a toilet of conventional shape and appearance, which is of simple construction and operation. The apparatus includes a bucket (50) that lies in a conventional tank (44) of long lateral (L) length and short front-to-rear depth, wherein the tank lies on the rear portion (40) of a toilet bowl part (20). Each end of the tank has a hole (122), and a bearing (124) extends through the hole and is fixed thereat to the tank. At least one end of the bucket is fixed to a trunnion (122) that extends through the bearing and that is fixed to a lever (64) lying immediately outside a tank end wall (100), with pivoting of the lever resulting in pivoting of the bucket. A deflector (82) lies at the bottom of the tank to one side of the water exit hole to minimize splashing and to concentrate water at the exit hole. At least one end (94) of the bucket is rounded into about a half circle as seen in a plan view, to provide room for a water inlet pipe (54).Type: GrantFiled: January 28, 1998Date of Patent: March 30, 1999Inventor: Arnold Hennessy

Patent number: 5666674Abstract: A dump bucket toilet is described, with an improved support for the bucket, a manual control that can save water, and an outlet region which efficiently directs dumped water into the toilet bowl. A support (60, FIG. 1) for the bucket has a mount portion (62) mounted on an upper portion of the toilet tank and has a largely downwardly extending support portion (100), the support portion pivotally supporting the middle of a rod (104) that extends between the opposite sides of the bucket. A manually operable control (152, FIG. 5) is operable in a full-flush mode to pivot the bucket by a first angle to a full release position to release almost all bucket water, the control being operable in a second partial-flush mode to pivot the bucket by a smaller second angle to release about half of the bucket water. A funnel (24, FIG. 1) extends at least four inches above the bottom of the container, with the funnel walls forming an included angle of about 14.degree. to efficiently direct the dumped water.Type: GrantFiled: March 24, 1995Date of Patent: September 16, 1997Inventor: Arnold Hennessy

Patent number: 5487193Abstract: A water saver toilet is provided, of the type that applies a vacuum to the toilet bowl outlet to assist flushing, which effectively uses the vacuum and which can be of low height. The toilet bowl outlet includes upper and lower trap devices (44, 50 in FIG. 2) connected by a trapway (46), with a vacuum source applied to the trapway during a flushing to pull out water and debris from the toilet bowl. One vacuum source (FIG. 3) includes a largely horizontal diaphragm (76) which separates a water chamber (82) from a vacuum chamber (80). The water chamber is initially filled with water, which is rapidly emptied during flushing, causing the diaphragm to rapidly fall from an upwardly bowed configuration (76) to a downwardly bowed configuration (76A). The vertically moving diaphragm produces a vacuum in the vacuum chamber that is connected to the trapway.Type: GrantFiled: August 27, 1993Date of Patent: January 30, 1996Assignee: Fluidmaster, Inc.Inventor: Arnold Hennessy

Patent number: 5426794Abstract: A vacuum assisted toilet is described, of the type wherein the toilet bowl outlet has a lower trap that is open to the passage of air therethrough except during each flushing when a vacuum is applied, which uses the vacuum more effectively. A vacuum source (46, FIG. 3) includes a first container portion (107) that holds water between flushings, with the water released during a flushing and creating a vacuum in a second portion (106) of the container that is coupled through a vacuum conduit (48) to the toilet bowl outlet. Instead of constantly coupling the second portion of the container to the bowl outlet, the second portion of the container is allowed to progressively expand but remain substantially unconnected to the bowl outlet until a predetermined amount of expansion (to 108) when the second portion is suddenly connected through the vacuum conduit (48) to the bowl outlet.Type: GrantFiled: February 10, 1994Date of Patent: June 27, 1995Assignee: Fluidmaster, Inc.Inventor: Arnold Hennessy

Patent number: 5406652Abstract: A water source (12, FIG. 1) is provided for mounting on a toilet housing (32) rearward of the toilet bowl (18), which has a small rearward-to-forward depth (D) and low height (H), and which enables close control of the flow of water and any vacuum to the toilet bowl and its outlet. The source includes a frame (40) for mounting on the rearward portion of the toilet housing, the frame having two wide holes (50, 52) and a diaphragm device (54, 56) extending across each hole to separate water regions (60, 62) from air regions (64, 66) that lie on opposite sides of the diaphragm. The holes and diaphragms form two horizontally spaced water supply units 42, 44 that lie on opposite sides of the toilet bowl outlet 24 to efficiently use space. A spring or weight biases each diaphragm to compress the water region. The two water regions are connected together and to a flush valve (14) for supplying water to the toilet bowl.Type: GrantFiled: April 30, 1993Date of Patent: April 18, 1995Assignee: Fluidmaster Inc.Inventor: Arnold Hennessy

Patent number: 5404597Abstract: A vacuum assisted toilet wherein a vacuum is applied between upper and lower traps (40,44 in FIG. 2) of a toilet bowl outlet during a flushing, wherein the lower trap is constructed to more reliably assure that an air passage (64) above a pool of water (52) of the lower trap will quickly close near the beginning of a flushing and will remain open between flushings. The lower trap has a lower wall (50) that holds a pool of water (52) with a pool top (62) of predetermined height (A) between flushings, and has an upper wall (60) spaced above the pool top to form an air passage. The upper wall forms a narrow but tall vent (100, FIG. 4) of the air passage, which assures that the air passage will always be open between flushings, and with the narrow but tall vent being quickly closed by water rapidly flowing therethrough at the beginning of a flushing.Type: GrantFiled: January 24, 1994Date of Patent: April 11, 1995Assignee: Fluidmaster, Inc.Inventor: Arnold Hennessy

Patent number: 5386596Abstract: A water saver toilet is provided, of the type that applies a vacuum to the toilet bowl outlet to assist flushing, which effectively uses the vacuum. The toilet bowl outlet includes upper and lower trap devices (44, 50 in FIG. 2) connected by a trapway (46), with the lower trap device being initially unobstructed. At the beginning of flushing, the initial water flow causes obstruction of the lower trap device to air flow, and a vacuum is then applied to the trapway to pull out water and debris from the toilet bowl. One toilet (FIG. 5) is of the urinal type, and includes a container (214) lying within a water tank, with the lower end (218) of the container opening to the water tank, and with the upper end (219) of the container connected by a vertical vacuum pipe (221) to the trapway.Type: GrantFiled: September 20, 1993Date of Patent: February 7, 1995Assignee: Fluidmaster, Inc.Inventor: Arnold Hennessy

Patent number: 5142712Abstract: A vacuum assisted toilet is described wherein a vacuum is applied to a toilet bowl outlet during flushing, which avoids malfunctions that could allow sewer gas to escape, and which uses flushing water effectively. The toilet bowl outlet includes upper and lower trap devices (40,44, FIG. 5) coupled by a trapway (42), with the lower trap device forming an unobstructed air passage when no water is moving therethrough but which includes a trapping region (64) that completely fills with water and forms an airflow barrier during flushing. The vacuum source includes a container (72, FIG. 1) in the toilet tank, with the container fixed in place in the tank to lie stationary therein, and with an ordinary flush valve (23) lying outside the container, so substantially the only part of the toilet that moves during flushing is the long developed and reliable flush valve.Type: GrantFiled: November 26, 1990Date of Patent: September 1, 1992Assignee: Fluidmaster, Inc.Inventor: Arnold Hennessy

Patent number: 4707868Abstract: A diaphragm valve for a toilet flushing mechanism, and a hydraulic flushing assembly using the valve, control water mains pressure for the pressure flushing of toilets with small quantities of water. Water mains pressure is used to retain a flexible diaphragm against the orifice through which flushing water from a pressurized tank can flow through the valve when flushing action is desired; flushing is initiated by temporarily lowering the water pressure applied to retain the diaphragm. Various designs of pressurized tank can be used to provide a constant or variable volume flush, which can be less than six quarts or liters.Type: GrantFiled: May 27, 1986Date of Patent: November 24, 1987Assignee: AHED Research and Development Inc.Inventor: Arnold Hennessy
