Publication number: 20080173180Abstract: A machine for the preparation of a hot drink with a housing and a brewing chamber, wherein the housing is provided with a connection region through which the brewing water is passed to the upper part of the brewing chamber. In order to seal the inflowing brewing water against the environment at the connecting point between the housing and the brewing chamber in a simple, economical and wear-resistant manner without complex locking mechanisms being needed, a seal is inserted into the upper part of the brewing chamber, wherein the seal and the connection region are automatically pressed together when the brewing chamber is inserted into the machine such that the connecting point between the connection region and the upper part of the brewing chamber is sealed against the environment.Type: ApplicationFiled: January 9, 2008Publication date: July 24, 2008Applicant: WMF WURTTEMBERGISCHE METALLWARENFABRIK AGInventors: Cornelius Boerner, Sander Dollner, Armin Startz

Patent number: 6513419Abstract: Described is a coffee machine (1) comprising a brewing member (5, 5′), a support surface (15) for ground coffee and a member (3, 6, 7) for applying water to the ground coffee, in which it is possible to level off the ground coffee positioned on the support surface (15) in a constructionally simple and generally applicable manner to obtain a layer having a substantially uniform thickness. To this end there is provided a member (22, 24, 25, 122, 222, 322) which guides water in a purposefully non-uniform manner over the ground coffee such that the ground coffee is distributed over the support surface (15) in a layer having a substantially uniform thickness.Type: GrantFiled: December 1, 1999Date of Patent: February 4, 2003Assignee: WMF Wurttembergische Metallwarenfabrik AGInventors: Siegfried Huber, Günther Nagel

Patent number: 5146839Abstract: A brewing means (1) for a coffee machine with a brewing chamber (3) is described, which is disposed in a housing (2) provided with an opening (9) on a front side. The opening (9) can be closed by means of a closing element (10) sealed against the opening. A hot water line (11) is furthermore provided, which supplies hot brewing water to the brewing chamber (3) under pressure and supports at the same time the sealing of the opening (9). In order to design such a brewing means (1) in such fashion that the service life of the seal (21) can be increased, it is suggested that the seal (21) comprises a flexible membrane disposed between a sealing chamber (22) connected to the hot water line (11) and a sealing seat (19), which can be arched and pressed against the sealing seat by means of the pressure.Type: GrantFiled: February 4, 1991Date of Patent: September 15, 1992Assignee: WMF Wurttembergische Metallwarenfabrik AGInventors: Karl Gockelmann, Rudi Geiger

Patent number: 4993315Abstract: A coffee percolator having a brewing chamber wherein at least one of the boundary wall surfaces of the brewing chambr is adjustable transversely of the direction of flow of the hot water through the coffee powder so that the thickness of the coffee powder bed in the direction of flow may be kept substantially constant for the coffee charges of varying size. The coffee percolator may include a brewing sieve having a support sieve with openings of a size exceeding the dimensions of the ground coffee particles and a fine sieve supported on the side of said support sieve facing towards the brewing chamber and having openings of a size smaller than the dimensions of the ground coffee particles.Type: GrantFiled: June 16, 1988Date of Patent: February 19, 1991Assignee: WMF Wurttembergische Metallwarenfabrik AGInventors: Siegfried Huber, Hans Motsch, Hermann Riegert, Rolf Ritter, Erwin Scholl, Konrad Walter, Gehard Wittlinger

Patent number: 4732079Abstract: Described is a coffee percolator having a coffee meal supply container mounted at an upper portion thereof, in which heating of the coffee meal supply by the heat of the coffee percolator and the resultant loss of volatile aroma substances are avoided. This is accomplished by providing a cooling system effective to cool the bottom of the supply container. In a preferred embodiment the supply container is cooled by means of air aspirated by a fan through an air flow path extending along the bottom of the supply container and subsequently returned to the environmental atmosphere.Type: GrantFiled: February 25, 1986Date of Patent: March 22, 1988Assignee: Wurttembergische Metallwarenfabrik AG.Inventors: Erwin Princz, Hans Motsch, Peter Pulvermuller

Patent number: 4583449Abstract: The invention relates to a coffee percolator for selectively making normal coffee or espresso, comprising a water flow path extending between a cold water supply inlet and a brewing unit, said flow path being divided into a first branch including a pressure pump, and a second branch including a valve adapted to close or be closed in the espresso making mode, and further comprising control means for activating said valve(s) and/or said pump in response to the selection of the type of coffee to be made. The invention is directed towards the provision of a coffee percolator of this type, which is of simplyfied and economic construction and substantially failure-proof. This is achieved by providing that the flow path is employed in common for the water used for making espresso and normal coffee, and is only divided adjacent the pump into the first flow path branch including the pump and the second flow path branch forming a bypass across the pump.Type: GrantFiled: April 30, 1984Date of Patent: April 22, 1986Assignee: Wurttembergische Metallwarenfabrik AGInventors: Artur Dangel, Josef Frech, Willi Niess, Rolf Prillipp, deceased, Hermann Riegert, Gerhard Wittlinger, Siegfried Anderl

Patent number: 4512495Abstract: The invention relates to a saucepan lid having a lid handle detachably secured thereto, particularly for a steam pressure cooker, including monitoring elements disposed within said lid handle. Means are provided for permitting said handle to be detached from said lid without technical difficulties and to be safely re-attached thereto. To this effect the lid and lid handle are provided with projections and engagement recesses at locations permitting them to be brought into mutual engagement for attaching the handle to the lid and to be readily released from such engagement for detaching the handle, at least one such projection forming a movable component of a locking closure means. In a preferred embodiment the locking closure means is designed as a snap-engagement locking means (FIG. 1).Type: GrantFiled: April 13, 1984Date of Patent: April 23, 1985Assignee: Wurttembergische Metallwarenfabrik AG.Inventors: Ewald Bauer, Jurgen Krejza
