Abstract

Abstract A cold water pour-in beverage brewer having a generally C-shaped body with the upper and lower leg portions extending forwardly from an upright interconnecting leg portion. The body houses an integral inverted L-shaped receptacle formed by an elongated shallow cold water basin from adjacent the bottom of one end of which a relatively deep hot water tank depends. The cold water basin sets in the top of the upper leg portion of the brewer body and has an out-turned flange on its top edge which rests for support on an in-turned flange on the edge of the top opening in the body. A cover fits over and completely covers the cold water basin and rests thereon. The cover has a pour-in opening adjacent the front of the brewer. A pair of top beaker warmers are supported in tandem on a heater unit mounted on the cover rearwardly of the pour-in opening. The hot water tank is housed mainly within the upright leg portion of the body. A removable brewer funnel is supported underneath upper leg portion so that beverage from the funnel falls into a beaker supported on a heater located on the lower leg portion. A removable baffle plate closes the opening between the cold water basin and the hot water tank so to provide ready access to the interior of the hot water tank for cleaning.
