Definitions
- This invention has reference to coffee infusers of the type in which hot water from a boiler under pressure ⁇ passes through ground coffee contained in a suitable receptacle.
- VJ ith such apparatus if the infusion period is prolonged and the temperature of the vater is at or about boiler temperature (say about 200O F.), it is found that the coifee becomes a bad colour when in the cups.
- the object of this invention is to enable this disadvantage to be overcome and for this purpose the hot water, instead of passing directly from the boiler to the infusing receptacle, is led through a cooling device, which is adapted to reduce the temperature of the water coming from the boiler (for instance to about 16W-18()o before reaching the coffee in the infusing receptacle.
- the cooling device may be in various forms. In some cases it may be a coil or chamber exposed to the air or it may be in the form of a series of tubes contained in a casing, the hot water passing through the tubes and air flowing through the casing around them and, in order to regulate or vary the cooling effect automatically, a diaphragm or expansible capsule exposed to the hot water is adapted, in the event of the water not being suiiiciently cooled after passing through the cooling device, to open a damper controlling the flow of air through the casing; the additional flow of air will reduce the temperature of the water and, on the diaphragm accordingly contracting, the damper will more or less close.
- the control cock is arranged between the boiler and the cooling device.
- the present invention is applicable to apparatus of a kind commonly used in restaurants, a portion of one well known form of which has been chosen for illustration in the accompanying drawings in further describing the invention.
- Figs. 1 and 2 are elevations at right angles to one another showing one arrangement, Fig. 1 being partly in section and drawn to a larger scale than Fig. 2.
- Fig. 3 is a view corresponding to Fig. 2 of another arrangement, Fig. 4 isy a 16, 1925. serial- No. 9,654.
- Fig. 5 is a section on the line 5 5 Fig. 3.
- Fig. 6 is a sectional view of a part of Fig. 1 to the same scale as Fig. 2.
- Fig. 7 is a part sectional elevation corresponding to Fig. 1 of a further modification.
- the pedestal 1 which, as before, has two steam branches 2 leading to the jackets 3 of infusion receivers 4 and a control cock 6 has a water way 7 which in lieu of directly entering the infuser 8 that surmounts the portion 9 of the pedestal 1 is diverted, as by an obstructing screw plug 10, so that it passes through a lateral passage 11 to the inlet end 12 of a cooling element 13, and the outlet end 14 whereof leads through a passage 15 to that portion 16 of the water way that is above the plug 10.
- the element 13 as will be seen, is of oval shape in cross section.
- a nonreturn ball valve 17 is shown as inserted in the passage: 16.
- a number of straight tubes 18 extend between plates 19, 2O in a casing 21, the plate 19 forming with the bottom 22 of the casing a chamber connected by piping 23 to the passage 11 of the pedestal 1, and the plate 20 forming with another plate 24 a chamber connected by piping 25 to the passage 15 of the pedestal.
- Air is admitted to the casing 21 by holes 26 and passes through tubular vents 27 to the chamber 28 which is equipped with a hinged lid 29 acted upon near its hinge by a lever 30 of well known type associated with a thermostatic capsule 31 in contact with the plate 2O which may for this purpose conveniently be dished as shewn.
- a screw such as shown at 32* in Fig. 6, may be employed.
- control cock 6a is adapted, as in the other cases, to admit hot water to the passageway 7a which however communicates through a port 11a with a chamber 32 constituted in part by a false bottom 33, a dished baffle 34 in the chamber 32 serving to cause the water to be diverted radially inwards under the bottom of the infuser 8a and to subsequently escape by passage 15a to the waterway 16at beyond the obstruction 10a and so past the ball valve 17a into the infuser.
- the bottom member 33 is shown as the "desired cooling.-
- lVhat I claim is l.
- an infuser pedestal formed With a Vertical Water Way, a Water cooler Connected at two points in the water Way and an obstruction in thelattjer 'adapted to bye-pass the water vvthroughthe Water cooler,k substantially as described.
- In cieeinakiiig apparatus ot thekkind in Whichw'ater from a boiler under pressure 'is forced through the lottoin "of an infuser, an infuser pedestal formed with a Vertical Water way, said pedestal'constituti'ng a 'false bottom 'for Vsuch rinfuser and forming Wit-h 'the latter 'a cooling chamber, said pedestal having furthera Water Way through Which equipped with nsn35 to assist in obtaining Vlatter Water may be caused toi enter the infuser, andobstruc'ting'means 'adapted to c'a-u'se the water to leave the Water way, flow through the cooling chamber and again enter the Water Way so that it enters the infuser reduced in temperature.
