  • Patent number: 10337662
    Abstract: The water cooler stand is an elevated stand for a water cooler that comprises a foot-operated mechanism for operating the spigot on the water cooler. The water cooler rests on the top surface of the stand and is retained there by a cooler cradle and two handle retention springs. A foot pedal located on the bottom, front leg of the stand is mechanically linked to a pressure plate in front of the spigot. A protrusion on the center of the front pressure plate will depress the push button on the spigot when the foot pedal is depressed. Use of the water cooler stand eliminates contamination and the spread of bacteria and germs to others. The water cooler stand may also comprise a slide-out sink basin and a hinged side tray to provide additional workspace.

  • Patent number: 10258502
    Abstract: A system for storing and delivering a predetermined amount of fluid includes a syringe including a barrel, a flange disposed at the proximal end of the barrel, and a plunger assembly configured to be received in the lumen of the barrel. The plunger assembly includes a piston and a plunger rod. The plunger rod is removably couplable to the piston at the distal end of the plunger rod and includes a thumb press flange at the proximal end of the plunger rod. The system further includes a stop feature that is removably couplable to the syringe or the plunger assembly. The stop feature is configured to arrest distal advancement of the plunger assembly relative to the syringe when the plunger assembly reaches a predetermined position relative to the syringe. The stop thus ensures that a predetermined amount of fluid remains in the barrel.

  • Patent number: 7455196
    Abstract: A support for manual grease guns has a base and lever-restoring mechanism. Grease guns conventionally have a pumping head with a barrel and lever joined thereto for cycling through pumping and restoring strokes between restored and depressed extremes. The restored extreme has the lever and barrel flared apart. Conversely, since the pumping stroke closes the flare, the depressed extreme has the lever brought alongside the barrel. The base has ground-engaging feet as well as clamps for clamping the grease gun tightly by the barrel, preferably with the lever projecting away for pedal-style depression in a generally vertical plane by a user stepping on it. The lever-restoring mechanism links the lever to the base, and yields under the user's step while the lever moves through pumping strokes, but restores the lever toward the restored extreme therefor as soon as the user takes his or her step off the lever.

    Abstract: A foot-controlled water faucet for regulating the outflow of water from a water faucet by means of air pressure comprises a compressing bladder connected with an air bladder in the water faucet by a passageway, a valve block, a ring body and a knob associated in proper order to form the water faucet. When stepping on the compressing bladder by foot the air inside is compressed and is squeezed to the air bladder in the water faucet via the passageway. The air bladder expands and pushes the platform as well as the stem in the ring body and the valve block respectively downward. The stem moves away from the opening of the valve block and water flows out. Water is stopped by releasing the compressing bladder which sucks back the air from the air bladder that is then contracts and allows the stem to move back to the original position. It can also be controlled by hand as an ordinary water faucet.

  • Patent number: 4349131
    Abstract: An apparatus for forming lather or soap foam for washing and/or shaving purposes comprises an actuation lever which simultaneously serves to drive a piston, a liquid soap-dosing pump and a membrane pump for generating compressed air. A perforated wall of a conduit or line enables blowing the compressed air into a dosed quantity of liquid soap located within a mixing chamber, to thereby form a coarse bubble lather or soap foam which subsequently is blown through a porous body, homogenized and compacted. Different embodiments of the apparatus can be realized and it is particularly suitable for use as a foot actuated structure and for producing hot lather for shaving. A preferred construction contains an intermittently operated heater for preheating the compressed air, to thereby accomplish a particularly effective generation of hot lather.

  • Patent number: 4231494
    Abstract: A connector is provided for attachment of a syringe to a dispenser adapted to provide measured quantities of pressured gas to the syringe to displace the contents of the syringe in measured drops. The connector includes a flexible conduit attached at one end to the dispenser and attached at its opposite end to the filling end of a syringe while gripping the oppositely disposed projections, or "ears", of the syringe. There is an externally threaded tube at the syringe end of the flexible conduit, terminated by a stopper member which has a cylindrical end portion sized to fit loosely within the filling end of the syringe, which end portion is joined to a sealing flange. The sealing flange abuts the flat surface at the filling end of the syringe while the syringe "ears" are retained within oppositely disposed channels after a knurled ring on the externally threaded tubular member is rotated.

  • Patent number: 4221359
    Abstract: A hydraulic valve normally mounted at a convenient level for manual operation on a machine can be operated by a person's foot as opposed to his hand. Towards this end, there are provided mounting means for mounting the valve in an upside down position at the same level together with an elongated tube extending from the normally existing manually operable portion of the valve vertically downwardly terminating short of the floor. A transverse foot pedal is pivoted to the machine frame at the level of the lower end of the tube, this lower end in turn being pivoted to the same foot pedal at a point spaced from the first pivoting point. The arrangement is such that rocking movement of the foot pedal will actuate the valve in the same manner as manual actuation when the valve was upright.

  • Patent number: 4170046
    Abstract: A foot liquid dispenser has a liquid reservoir on a base. A liquid sprayer on the base is connected to the reservoir and is mounted to discharge at a predetermined height above the base and in a predetermined direction. The sprayer is operated by a lever actuated by a bail pivoted on the base and having a small transverse bar projecting beyond the base and engageable by the user's foot. The bar is pivoted to travel from an upper position substantially above the spray then through the spray to a lower position substantially below the spray so the user's foot in depressing the bar is sprayed both bottom and top and excess liquid falls free of the dispenser.
