Abstract: A compact coffee maker can prevent the dirt and ashes enter into the pot body and the handle has an excellent heat isolating capability. This compact coffee maker includes a pot body, a conduit, a filter, and a pot base. The pot body is made from carafe and is provided with a spout. The washer is disposed at the outside of the external threaded slot, accordingly, there is not a leakage found between the pot body and the pot base. The conduit is disposed within the external threaded slot and the filter is disposed at the opening of the pot body. The conduit passes through the center opening of the filter and the permeable section of the conduit will spray the hot water onto the filter radially. When the lid is lowered down, the curve slot is met with the spout of the pot body. By this arrangement, the coffee can be directly poured onto a cup without removing the lid. On the other hand, the lid with a curve slot is disposed on the pot body, the dirt and the ashes will not fall onto the pot body.

Abstract: A cast cup provided with a heating element is secured to the bottom plate of a reservoir for a percolator. The cup is inserted into an opening in the bottom plate of the reservoir and has an upper flange and a lower flange. The upper flange is secured to the top surface of the bottom plate by means of swaging. The seal is water-tight. The lower flange has a sealing compound applied to it and is sealed against the underside of the bottom plate when the upper flange is swaged to the top surface of the reservoir's bottom plate.

Abstract: A generally C-shaped coffeemaker housing holds a heated carafe on one horizontal leg and a water spreader on the other with the vertical leg enclosing an accessible water reservoir having an apertured bottom wall. The housing has a pump and heated chamber in the bottom for delivering heated water to the spreader and a tubular outer conduit connecting the reservoir and chamber with a concentric spaced inner conduit between the chamber and reservoir interior. An integral one way valve is provided on the inner conduit between the conduits and the chamber permitting cold water into the chamber through the outer conduit and hot water exit through the inner conduit.

Abstract: A coffee percolator includes conventional elements such as an electrical heating element, an on/off switch for energizing the heating element and a thermostatic switch for deactivating the heating element when the brewing coffee reaches a predetermined first temperature. The coffee percolator further includes a conventional pump and a coffee ground receptacle disposed in the upper portion of the inner chamber of the percolator. The invention resides in the inclusion of a temperature actuated pump for deactivating the pump when the temperature of the fluid in the inner chamber of the percolator is less than a second temperature. The second temperature is below the first temperature which activates the thermostatic switch. The temperature actuated pump control means includes an aperture disposed in the coffee pump to release fluid under pressure from the pump and thereby to disable the pump at low fluid temperatures.

Abstract: A container or reservoir for liquid to be heated, has a pump well and heater assembly secured to and depending from the bottom wall of the container, and a pump and pump tube assembly can be positively locked on the well for pumping function but is easily and quickly removable for cleaning or replacement. The assembly is locked on the well by a retainer plate fixed to an outer pump tube and having locking portions coactive with locking portions on the side wall of the well, with said outer tube being telescopically slidable and rotatable on an inner pump tube which carries a pump plate to seat in the well and a valve disk co-operative with said valve plate. A compression spring is disposed between the retainer plate and the pump plate locking portions to hold the retainer plate interlocked with the well locking portions and to hold the pump plate seated in the well.
