Abstract: Novel infusion-making machine characterized by a filter consisting of superposed crowns located in a centrifuging chamber eccentric with respect to a central shaft rotated by a motor, and submitted to a compound motion. The adjustments of the crowns permits infusing and filtering over a broad range so that the machine may be used in a variety of applications.

Abstract: A coffeemaker having a ground coffee basket and a heated brewing water spreader positioned generally above the ground coffee basket wherein the spreader includes a generally vertical cylindrical dam wall extending upwardly from a generally flat foraminous wall for permitting brewing water to flow over the dam wall, through an overflow passage and into the ground coffee basket when the spreader has been filled with heated brewing water above the upper surface of the dam wall.

Abstract: An automatic coffee brewer including a water heating tank, a funnel-like holder for ground coffee, a siphon device for dispensing a predetermined amount of hot water from the tank through the grounds holder, and a bypass valve for directing approximately 40% of the hot water around the grounds and directly to an unheated, thermo-insulated beaker so that the resultant brew has extracted about 60% of the soluble solids in the coffee to yield a better tasting brew free of bitterness and astringency. The use of the thermo-insulated beaker enables the brewed coffee to be kept hot without further heating for several hours and avoids bitterness derived by continuous heating.

Abstract: A pour-over type coffee brewing apparatus is disclosed adapted for mounting under a cabinet or shelf and having a water receiver assembly containing means for immediately heating a charge of water and having a temperature-actuated valve for discharging the heated water at an appropriate temperature into a brewing vessel. A thermostatic device is included for automatically monitoring and controlling the activation of the heating means.

Abstract: A heater unit for heating a quantity of water in a reservoir. The flow of water from the reservoir to the heating unit is controlled by thermally responsive means disposed to be exposed to vapors from the water as it is heated by the heating unit. The temperature sensing means comprises a flat bimetallic member for operating a valve to control flow between the reservoir and heating unit. A pan-like heating unit structure is a well in which a spiral heating element is positioned and a sandpipe forms the outlet for the heating unit and operates to back-water over the heating element. A generally horizontal flow channel receives water from the reservoir and leads the water to the top of the well.

Abstract: Coffee brewer apparatus adapted for the selective brewing in a brewing cartridge of coffee from ground coffee charges either in loose form carried on a cup-shaped filter sheet, or in enclosed form carried in a filter bag. The brewer apparatus includes selectively mountable hot water delivery elements and an adaptor selectively disposable in the cartridge for use in combination with the delivery element adapted for brewing coffee with bagged charges. The brewing cartridge is selectively positionable on a mounting bracket. The mounting bracket may be retained to a support wall portion of the brewer by the selectively mounted water delivery element.

Abstract: An electric drip coffeemaker wherein a dry ground coffee dispenser is supported at an upper overhanging portion of a housing, a carafe is positioned on a lower stand portion of the housing at one side of the dispenser, and a ground coffee basket is selectively positionable on guideways which are provided at the lower portion of the dispenser and at the top wall of the housing above the carafe.

Abstract: A beverage brewer wherein hot liquid is delivered from a heating tank to a brewing cartridge as a result of introduction of additional liquid into the heating tank from a suitable source. An aspirator is provided in combination with a spray device for preventing dripping of hot liquid from the apparatus as a result of the expansion of the newly introduced liquid resulting from the heating thereof in the heating tank. The aspirator is removably associated with a reservoir structure and the reservoir structure is removably carried on the removable cover of the heating tank. A transfer duct between the reservoir structure and spray device is removably connected to the aspirator and is displaceable from a position overlying the heating tank to laterally thereof for facilitated removal of portions of the apparatus upwardly from the tank.

Abstract: An automatic beverage-making apparatus is described which has a stand and a receptacle and water may be supplied to solid material such as ground coffee in the receptacle by a pipe means within the stand, said pipe means being provided with a heater to heat the water and means for controlling the throughput of water, the time for which water flows through the pipe means and the energisation of the heater respectively.
