16 Claims.
Our present invention relates generally to improvements in the art of producing beverages such as hot coffee, tea or the like, and relates more specifically to various improvements in the construction and operation of beverage producing devices for automatically and effectively converting granular material and liquid into wholesome beverage.
An object of the present invention is to provide an improved beverage producer which is simple and compact in construction, and which is moreover highly eificient in use.
, It has heretofore been proposed as shown in the prior Patent No. 2,190,270, granted February 13, 1940, to Ambrose A. Peters, to provide a coffee making assemblage wherein hot water from a stationary heater is caused to permeate upwardly through successive batches of coffee grounds confined in portable containers which are interchangeably associable with the fixed discharge pipe rising from the heater, and in which the finished coffee may be delivered from the portable permeating containers to any one of several coffee dispensing receptacles through spouts carried directly by the containers. This prior coffee fabricating equipment is especially adapted for use in restaurants and other establishments wherein large quantities of fresh coffee should constantly be available, and while the patented coffee maker has proven highly successful for its intended purpose, it is not sufficiently rapid in action and flexible enough to permit quick and unhampered dispensation of the finished coffee to diverse places or localities of actual consumption, due to the fact that the successive batches treated and produced are relatively large and the final dispensing receptacles are bulky and cannot be readily transported from place to place. The prior system is also somewhat objectionable in that the equipment is relatively cumbersome and difficult to manipulate, and it also lacks sensitive and automatic controls whereby precise uniformity and excellence in final product is always assured.
It is therefore a more specific object of our present invention to provide various improvements in coffee producing apparatus of the general type forming the subject of the prior patent above identified, and which obviates the objec- 2 batches of uniform consistency, which may be quickly and conveniently dispensed with the aid of transparent portable receptacles of standard construction.
A further specific object of this invention is to provide an improved beverage producing assemblage which has enormous capacity While being compact, neat and highly attractive in appearance, and wherein the permeating operation is most effectively accomplished and is subject to automatic control.
Still another specific object of our invention is to provide an improved cofiee maker wherein a succession of relatively small batches of granular coffee can be rapidly and effectively treated for extraction of the wholesome ingredients to produce delicious coffee beverage in correspondingly small and readily dispensable batches, and in which the grounds containers and the final coffee urns may be conveniently applied to or removed from the machine.
An additional specific object of the invention is to provide an improved device for making coffee or similar beverages in an expeditious manner, at .minimum'cost, and with utmost safety to the operator. V
These and other specific objects and advantages of the present invention will be apparent from the following detailed description.
A clear conception of the several features constituting the present improvement, and of the mode of constructing and operating beverage producers built in accordance with the invention, may be had by referring to the accompanying drawing in which like reference characters designate the same or similar parts in the various views.
Fig. 1 is a diagram showing the improved assemblage and the controls thereof;
Fig. 2 is an enlarged central vertical section through one of the improved beverage grounds containers and a standard beverage dispensing receptacle, and a transverse vertical section through the Water heater and supporting base; and
Fig. 3 is a further enlarged transverse section through one of the grounds containers, taken along the line 3-3 of Fig. 2.
While the invention has been shown and described herein as being especially applicable to the production of coffee beverage, it is not our desire or intent to thereby unnecessarily restrict the scope or utility of the improvement which is applicable more generally to the production of various kinds of permeated beverages.
Referring to the drawing forming a part of this specification, the improved beverage producing system shown therein by way of illustration comprises in general, a stationary electrically energized water heater having a valve controlled supply .pipe 3 communicating with any desirable fresh water pressure source and a fixed hot water discharge pipe I, the latter rising at an inclination from the uppermost portion of the heating chamber 3 and having a tapered socket 3 at its upper extremity; a plurality oi interchangeably similar containers In each having an inner central compartment II for confining a batch of granular beverage producing material|2 and being provided at its lower end with a central tapered nipple or plug l3 adapted to i'rictionally engage the stand pipe socket 9, while its upper end is provided with a down spout l4 communicating with the top of the compartment II and disposed closely adjacent to the outer side wall of the container Ill; a removable filter l5 carried by a detachable closure cap or cover l3 associated with each of the containers l0, the filter |5 being interposed between the spout l4 and the compartment II; a plurality of interchangeably similar beverage dispensing receptacles each formed symmetrical with respect to a central axis and having a handle l8 and a cover l3 associated with the upper neck portion 20 thereof; and a support 2| for the receptacles l1 located in central alinement with the container spout I4 and laterally of the inclined riser pipe I so as to permit unobstructed disposition of the successive receptacles directly beneath the spouts I4.
The electrically energized water heater 5 which is shown diagrammatically in Fig. l and in transverse section in Fig. 2, consists primarily of a slightly inclined cylindrical drum 22 forming a suitable enclosure for the liquid filled heating zone or chamber 8, and being housed and normally concealed within an ornamental frame or base 23; and one or more U-shaped electric heating elements 24 confined within the chamber 3 and connected to a main electric energy supply 4 3315 open. The arrangement of the electrical connections and switches for the water heater I 5 is such that when the main switch 23 is closed,
- the heating elements 24 will be energized and will function to continuously heat the water within the'chamber B; and when the temperatureoi' this water reaches a predetermined high degree line 25 having a manually actuated cut-out switch 26 associated therewith. A thermostat 21 is operatively associated with a switch 28 interposed between one terminal of the heating elements 24 and the main line 25, and this switch 28 is adapted to break the heater circuit automatically when the temperature of the water in the chamber 8 reaches a predetermined high value. The fresh water supply pipe 6 communicates with the heater 5 through a strainer 29 and past a magnetically actuated automatic control valve 30 and a manually operable regulating valve 3|; and the delivery end of the supply pipe 6 is provided with an elongated tubular end 32'disposed within the lower portion of the heating chamber 8, and having a series of downwardly directed ports or orifices 33 in the bottom thereof. The magnetically actuated fresh water control valve 30 is connected to main line 25 in series with a magnetically actuated switch 34 the operation of which is controllableby means of two push button switches 35, 36 one of which is nor- "mally open and the other of which is merely athe temperature controlled switch 23 will automatically open to de-energize the heating elements 24.- When the manually actuated valve 3| has been set to predetermine the rate of flow of the fresh water, and the push button switch 35 is closed, the lamp 31 will light and the magnetically actuated valve 30 will be opened so as to automatically regulate the quantity of fresh water delivered to the heater from the pressure source.
The receptacle support 2| is vertically movably supported upon the base frame 23 by means of a central spindle 33, and is constantly urged toward uppermost position either by means of a lever 44 and weight 43 as in Fig. 1, or by a coil spring 33, as in Fig. 2. The disk-like movable support 2| is provided with an electric heating element 40 one terminal of which is constantly and directly connected with the negative branch of the main line 25, while its opposite terminal is adapted to be interchangeably connected to the positive branch of the main line 25, either through the lever switch 4|, or through another magnetically actuated switch 43. This opposite terminal of the heating element 40 is connected to the upper contact of the two way switch 4|, and the lower contact of this switch 4| is connected with the solenoid or actuating coil 42 of the magnetic switch 34. A similar solenoid or actuating coil 49 of the magnetic switch 48 is connected in parallel with the coil 42 of the magnetic switch 34, and the pivot terminal of the switch 4| is always connected to the positive branch of the main line 25; so that when the push button switch 35 is closed, both of the magnetic switches 34, 48 will automatically close if the lever switch 4| is engaging its lower contact.
Whenno receptacle I! or an empty one, is resting upon the movable support 2|, the lower contact of the switch 4| will be closed, and the heating element 40 may then be energized by closing the push button switch 35. Such closing of the switch 35 will immediately cause the magnetic switches 34, 43 to close, and the closing of these magnetic switches will simultaneously illuminate the lamp 31, energize and open the fresh water control valve 3|], and energize the heater 40. The apparatus will then function to deliver beverage to the receptacle 1 disposed upon the support 2|, and when this receptacle becomes filled to a predetermined extent, the circuit through the lower contact of the switch 4| and through the solenoids 42, 49 will be interrupted to simultaneously open the switches 34, 48, extinguish the lamp 31, and close the magnetic valve 30, thereby stopping the flow of fresh Water to the heater 5. The heating element 43 will be momentarily de-energized, but will be quickly re-energized when the lever switch 4| engages its upper contact, and will remain active so long as the liquid filled receptacle I1 is permitted to remain upon the support 2|.
The push button switch 35 is of the type.
wherein when the button is released after clos= ing the circuit controlled thereby, it will automatically return to open position; and the other push button switch 35 is merely a safety switch and may be of the type wherein the circuit controlled thereby is normally closed but will be interrupted by pressing the button. Closing of the switch 35 will therefore energize the coils 42, 4! simultaneously, and these coils will remain energized until either of the switches 36 or 4| are opened, whereupon the switches 34, 48 will automatically open.
The weight of the support 2| and spindle 38 may be counterbalanced either by means of a weight 43 adjustably. suspended from a lever 44 which is pivotally attached to the spindle 38 and coacts with a fixed fulcrum 45 as shown in Fig. 1, or by means of an adjustable tension spring 39 as in Fig. 2. Several other stationary electric warmers or heaters 46 for other liquid filled receptacles I1, may also be connected to the main line 25 and provided with independent switches 41 as illustrated in Fig. 1, and these auxiliary heaters 46 may be mounted on the base 23 around the movable support 2| and riser pipe 1.
The upwardly extending laterally inclined hot water discharge pipe 1 which communicates with the uppermost portion of the chamber 8, may be housed within an ornamental and pro-' tective tubular casing 50 and the tapered socket 3 may rest upon the upper end of the casing 50 and is rigidly attached to the outlet end of the pipe 1 by a liquid tight joint. The interchangeably similar containers ||l may be formed of sheet metal, and each of these containers ID is preferably provided with a lower annular apron 5| depending from its chamber H and below the lower end of its nipple plug [3, so that the container l may be set firmly upon a fiat surface without obstruction by the lower plug thereof. The interior of each nipple plug I3 is provided with a one-way ball check valve 52 which will permit hot water to flow freely through the plug and into the percolating chamber II, but will not permit reverse how of the liquid, so that no coffee can flow into the heating chamber 8 and the containers ||I may be removed from the socket 9 without danger of dripping. The plugs l3 may be formed of soft rubber and are tapered for snug coaction with the socket 9, but the containers III are freely upwardly removable and replaceable by other similar containers. The upper closure covers iii of the containers ||l may be provided with handles as shown, and are removably attachable to the containers by bayonet joints 53 as shown in Fig. 3 The cloth filter 15 which is suspended from each cover I6, is attachable to a spider 54 secured centrally to the cover, by means of a draw string 55 as shown in Fig. 3, and the filter l spans the upper end of the permeating chamber so that no liquid can escape from this chamber to the spout t4 without passing through the filter cloth. The beverage producing material l2 may be coffee grounds, tea leaves, or any other relatively granular beverage stock, and the spouts |4 are disposed closely adjacent to their supporting containers in and are open at both ends.
The beverage receiving and dispensing receptacles ll of which there may be any desired number provided depending upon the capacity of supply pipe 6 may be connected to any suitable source of water under pressure.
When it is desired to utilize the improvedbeverage producing apparatus, the manually operated control valve 3| should be set to produce the desired rate of flow of fresh water from the supply pipe 6 to the heater 5 when the valve 30 has been opened, and the main switch 26 should chamber 8.
the bottom of the chamber 8 will force hot liquid.
I1 is of sufficient volumetric capacity to hold the I beverage which can properly be produced from a be closed, thus energizing the heater elements 24. A container Ill having a fresh batch of materialv i2 therein should then be applied to the.
The return of lever switch 4| from its upper to its lower contact deenergizes the heater 40 even though this same lower contact operates to maintain the heater energized while the receptacle I1 is being filled. Thus when the lever switch 4| shifts from the lower contact to the upper contact, it shifts control of the heater 40 so that its return to the lower contact will no longer maintain the heater 4!) energized,
The thermostat 21 will prevent excessive rise of the temperature within the chamber 8, and the regulating valve 30 will effectively control the delivery of fresh liquid to this chamber and will stop thexdelivery when the switches 34, 48 are open and'no container I0 is associated with the socket 9, or when the safety switch 36. is opened. When a batch of beverag has been completed, the container l0 may be removed and replaced When the hot liquid I When the liquid in auxiliary heaters 46, whereupon another empty receptacle ll may be placed upon the support II.
In this manner successive batches of beverage can be quickly and effectively produced and the completed batches may be maintained in heated condition until they are to be dispensed. The system operates automatically and is efiectively protected against dangerous pressure conditions within the chamber 8 by the thermostat 21 cos operatingwith the switch 28. In order to place the system in inactive position, it is only necessary to manipulate the push button switch 36, and when it is desired to de-energize the heating elements 24, it is only necessary to open the main switch 26.
From the foregoing detailed description it will be apparent that our present invention provides an improved beverage producing system which is extremely simple in construction and highly efllcient in operation. The performance of the apparatus is automatic except for the replacement of the containers l and of the receptacle l1, and the final beverage is automatically maintained in heated condition so that it may be served hot. The improved construction of the heater with its inclined hot water discharge pipe 1, permits the use of standard receptacle H which is formed symmetrical with respect to central vertical axes, and also permits the location of the discharge spouts l l closely adjacent to their containers Ill. The provision of the aprons 5| on the containers in also permits these containers to be set vertically upon fiat surfaces, and the indicator light 31 effectively shows when the system is in operation and beverage is being produced. The operation of the heating element 40' which is associated with the. movable support 2| is entirely automatic, and the unit can readily be adjusted for co-operation with relatively rough supporting surfaces by adjustment of the legs 56. The improved beverage producing apparatus has proven highly satisfactory and successful in actual commercial use, and is adapted to produce successive batches of delicious beverage in rapid succession and at extremely moderate cost.
It should be understood that it is not desired to limit this invention to the exact details of construction or to the precise mode of operation, herein shown and described, for various modifications within the scope of the claims may occur to persons skilled in the art.
