Abstract

495,669. Coffee - infusion apparatus. STILL & SONS, Ltd., W. M., and STILL, E. H. Oct. 18, 1937, No. 28314. [Class 129] Coffee is infused by first passing a flow of comparatively cool water through the infusion chamber and thereafter hot water is passed to complete the extraction. The Figure shows an apparatus for this method of infusion. Hot water from a boiler passes through a valve b<1> to a pipe b leading to a device u comprising a thermostatic device d carrying a valve e by which cold water is admitted to mix with the hot water so that comparatively cool water 120‹ F. passes to the infusion chamber a. The cold water supply is shut off when a dashpotcontrolled valve c<1> is closed by spring action. This valve c<1> is automatically opened when the hot water valve b<1> is opened. A cam g on the spindle of the valve b<1> depresses a lever h which through a rod i depresses a lever c<2> to open the cold water valve c<1>. The rod i has a slope piece i<1> by which it is swung to the right out of contact with the lever c<2> whereupon the valve c<1> is able to return under spring action but retarded by the dashpot n. Instead of the thermally controlled valve e an adjustable screw needle valve may be used, Fig. 2 (not shown). Specification 407,108 is referred to.
