Description
Background of the Invention
This invention relates to an automatic coffee making device which employs the use of hot water before contacting the coffee. There are a number of coffee makers of this type on the market but each of such devices has a number of defects or faults that cause the user inconvenience and difficulty during use of the device. For example, when the water begins to boil the pressure of the steam between the cover at the top and the walls of the water reservoir causes water or steam to leak down the outside of the coffee maker which may contact the electric wires so that a "short" may occur, the metal may rust and cause other difficulties and inconvenience. Also, the outlet at the base of the water reservoir permits the hot water to shoot directly down into the basket containing the coffee causing splashing of the hot water. The wall of the paper filter within the basket beneath the water reservoir often collapse so that the hot water passes between the paper filter and the basket and not directly onto the coffee grind. The silk screen at the base of the basket is permanently attached to the basket and is difficult to clean. The screen is often accidently punctured and since it is attached to the entire basket, a new basket must be purchased and replaced at an added cost and the inconvenience of obtaining a new basket. The water spreader which is attached to the basket is difficult for the user to remove as presently constructed and has other defects which require improvement. The warming unit at the base of the coffee maker also requires improvement since it permits water to leak through the base and reach the surface upon which the carafe rests.
I have, therefore, made a number of improvements to cure the defects and faults above mentioned which inconvenience the user making coffee with such coffee devices on the market at the present time so that such difficulties, among others, are eliminated and the making of coffee with my improved coffee maker becomes easy and a pleasure for the user.
The above and other objects of the invention will become more apparent when considered in view of the following specification and drawings.

Description of the Preferred Embodiments of the Invention
The present invention provides a coffee maker 10 comprising an upper housing, opposite vertical support walls 79 and a back plate 80 which covers a hollow compartment between said vertical support walls 79, said upper housing having walls 15 and having a top cover 11 for such upper housing which has a depending inwardly angled flange 12 extending around the cover set back from the outer edge 13 of the cover providing a shoulder 14 the width of the thickness of the wall 15 so as to make a fairly tight fit with the inner edge of wall 15 which contains the water reservoir 16 within the upper part of the coffee maker 10. Cover 11 has a shallow circumferential depressed portion 17 to receive the bottom of the filter housing 18 which is removably attached to the basket 19. Basket 19 has a shoulder 19' for seating the basket upon the upper edge of the carafe 20. Depressed portion 17 of the cover is a convenient place to place the basket 19 with its filter housing 18 when the basket is removed from the glass carafe 20. Any moisture or coffee dripping will accumulate within the depressed portion 17 and can be readily washed off when the cover 11 is washed. The inwardly angled flange 12 permits any moisture which may collect on the inside of cover 11 or between the flange 12 and wall 15 to flow into the compartment 21' containing the water reservoir 16 thus keeping the outer walls 15 dry and preventing water from flowing out of the upper housing and onto any of the switches and electrical wiring hereinafter described to avoid electrical "shorts".
Walls 15 provide the compartment 21' within which there is the reservoir 16 to receive water for coffee making. A bottom 22 acts to support the bottom 25 of the reservoir 16 and the compartment unit 21 by means of two opposed metal support arms 28 which are attached to the outer walls of compartment unit 21 and which have their ends 29 bent inwardly to receive a screw 29' in a screw hole to fasten and adjust the tightness and seating of the unit 21. The compartment unit 21 has an outwardly directed flange 24 which is also supported by an inwardly projecting shoulder 23. There is a space 21' between the compartment unit 21 and the water reservoir 16 acts as air insulation around the reservoir 16 and collects any moisture circular metal may accumulate within the space 21'. The bottom 25 of water reservoir 16 is attached to the bottom 26 of the compartment unit 21, preferably by spot welding, and both the compartment unit 21 and the reservoir 16 are preferably made of thin stainless steel. Water reservoir 16 has numerals and lines die stamped in the metal to indicate the water level for 4, 6, 8 and 10 cups of water for making coffee. A heating coil 27 is welded to the bottom 26 of compartment unit 21 which supplies heat to the metal bottoms 25, 26 thus heating the water within the water reservoir 16 when desired. Compartment unit 21 has an outwardly directed upper flange 24 for seating the compartment unit 21 upon shoulder 23.
A circular member 30, preferably of a ceramic material, is located along the central medial line in the circular opening of the bottom 25 of the water reservoir. Member 30 has an outwardly directed flange 31 which permits the seating of member 30 upon the short extension 32 of the circular opening of the bottom of compartment unit 26. Member 30 has a depressed circular chamber 33 and a circular pipe 34 which extends shortly below bottom wall 22 and communicates with chamber 33. Within the upper part of circular chamber 33 and member 30 there is a stainless steel metal plate 35 which has a series of fine openings 36 to permit the heated water within the reservoir 16 to enter into the member 30, chamber 33 and pipe 34. A rubber sleeve 37 surrounds pipe 34 and acts as an insulator for pipe 34. A circular metal depending flange 38 is attached to the bottom 26 of compartment unit 21 and acts as a heat shield to prevent a certain amount of the heated air from heating coil 27 to pass between the coil 27 and rubber sleeve 37. A thermal valve 33' well-known in the art, is in the bottom of the water reservoir within the member 30 and opens and allows the heated water to start to drain out of the reservoir when it reaches a predetermined temperature. Attached to bottom 22 of compartment 21 is a circumferential depending outwardly dished flange 39 which prevents the splashing of the hot water when it leaves the pipe 34 and may contact and injure the user. Electric wires 40, 41 are attached to each end of heating coil 27 to heat the coil by movement of an "on-off" switch as will be hereinafter more specifically described. The hollow compartment between the vertical walls 79 contains most of the electrical wiring (not fully shown) for automatically operating the various electrical parts mentioned herein.
The carafe 20 with its basket 19 and spreader cover 44 therein is centrally placed upon a metal circular warming plate 42 which is attached to the base 43 of the coffee maker 10 so that it is centered directly beneath circular pipe 34. The warming plate 42 has a short vertical wall 45 and an outwardly directed flange 46 providing an air space 47 between flange 46 and the horizontal platform 48 at the base of the device. Platform 48 has a circular opening spaced from the wall 45 of plate 42 permitting circulation of air from the raised bottom walls 48 and between the air space 47 and platform 48 and wall 45 thus keeping the heat created by warming plate 42 from effecting the plastic walls and housing around the plate 42. Flange 46 also helps to retain the carafe 20 on the plate 42 which also collects any possible spillage of water or coffee and prevents same from reaching the electrical wiring associated with the warming plate 42. Warming plate 42 has a metal heating coil 89 attached to its underneath surface which is enclosed in a bottom cover plate 49 attached to plate 42. Warming plate 42 with its cover plate 49 is attached preferably by screws 90 at the corners to the housing of the device. A thermostatic control T2 shown in FIG. 10 well-known in the art, is attached to the warming plate 42 to maintain a temperature to keep the coffee within the carafe at a desired temperature for serving.
Spreader cover 44 is preferably circular and is adapted to fit snugly upon the upper part of circular basket 19 and comprises a horizontal member 50 which extends slightly beyond the outer wall 51 of basket 19 so that it may be easily lifted off basket 19 by the fingers of the user. It has a downwardly directed depending circular flange 52, the outer edge of which is slightly tapered inwardly so that it fits tightly upon the top of the basket 19 and within the upper edge of said basket 19. It also has a large dished circular central portion 53, the angular wall 54 of which extends above the upper surface of cover member 50 to catch all the hot water that shoots out of pipe 34 due to the pressure. The openings 56 on the bottom of said spreader cover permit such hot water to enter basket 19 through the small tapered openings 56 adjacent the outer portion of bottom 55 so that very little heat and pressure within the basket 19 is lost. The hot water then passes downward into a dished plastic cover member 57 for a circular plastic filter support wall member 58. Cover member 57 breaks the force of the hot water entering and has a large number of small openings on its bottom 59 which permits the hot water to enter into the support wall member 58. Cover member 57 has a circumferential flange 57' for seating the cover upon the upper edge of the support wall member 58. Member 58 has no bottom and has a large number of small openings 60 in the circular wall 61 so that the hot water passes into the cup-shaped paper filter 62 which contains the coffee grind (not shown). If the fluted circumferential wall of the paper filter 62 is not supported, it often collapses and the hot water passes between the collapsed filter paper wall and the inner wall of basket 19 so that the hot water does not extract much of the coffee brew within the paper filter. By placing the cup-like support 58 within the paper cup filter 62 the circumferential wall of the paper filter 62 cannot collapse. Thus, the hot water acts on all the coffee grind within the cup-type filter 62.
The paper cup-type filter 62 with the ground coffee is placed within basket 19 and rests upon the silk screen 68 on the bottom of the shallow cap unit 66. The lower outer end of basket 19 has a threaded portion 65 to receive a circular inwardly threaded shallow cap unit 66 which has several radiating cross ribs 67 upon which there is a fine silk screen 68 through which the coffee extract flows into the carafe 20. Very often the silk screen is punctured and must be replaced or it may have to be cleaned from time to time if it is not washed frequently and foreign matter accumulates to clog up the fine pores of the silk screen 68. In the baskets heretofore used the silk screen was part of the entire basket and the complete basket had to be replaced. In the present invention only the threaded shallow cap 66 need be replaced and can easily be unscrewed by the user.
After all the coffee has drained into the carafe 20, a cap 69, preferably made of plastic and having a depending flange 70 adapted to fit within the neck of the carafe, may be placed on the carafe and turned so that opening 71 in the flange lines up with the pouring spout 72 to permit pouring of the coffee with cap 69 on the carafe. Flange 70 also has a self biased detent 83 which has a slot 84 to provide a spring effect to flange 70 so that it remains tightly in the neck of carafe 20 when the beverage is poured.
Carafe 20 has a downwardly sloping handle 73 with a plastic strengthening member 74 sloping at the same angle as the sloping wall of the carafe for holding the filled carafe more firmly and rigidly. A wide metal band 75, with inwardly bent ends, circumscribes the neck portion of the carafe 20 and is attached to the handle 73 by a long screw 76 passing through the upper part of handle 73 and the inwardly bent ends of metal band 75 and may be tightened through a nut (not shown). Handle 73 is spaced somewhat away from the sloping wall of the carafe so that when the fingers of the user grasp the depending handle 73, the users fingers are sufficiently far from the wall of the carafe to avoid the heat of the carafe containing the hot coffee.
At the lower front of the upper housing which contains the water reservoir 16 there are several switches and lights namely, an "off-on" switch 85, a "warm" light 86, a "brew" light 87, and a "push to brew" switch 88, which are all well-known in the art of coffee making machines. These switches and lights are properly wired as shown in FIG. 10 so that they operate the coffee maker in accordance with the following instructions.
In order to properly use the coffee maker of this invention, the following steps should be taken.
Remove the top cover 11 from the water reservoir 16 and fill the glass carafe 20 with cold water and pour it into the water reservoir 16 to the desired level indicated on the inside of the upright wall of the reservoir for making four to ten cups of coffee and replace the cover 11 on the top of the device. Place the paper filter cup 62 in the basket 19 and add the desired amount of coffee. A general measure of regular grind coffee is two level measuring tablespoons for each cup. For a weaker brew, water is added to the carafe 20 after the cycle is completed and for a stronger brew the amount of water is decreased slightly. Then place the filter support member 58 into the filter cup 62 which will support the upright wall of the paper cup. The cover member 57 is then placed on the support member 58. The spreader cover 44 is then placed on top of basket 19. The basket 19 and spreader assembly is then placed onto the empty glass carafe 20. Carafe 20, with its basket 19 and spreader cover 44 assembly, is then placed directly under the circular pipe 34 and centered on the warming plate 42. The electric cord 77 with its plug 78 is then placed into an electric outlet and the switch 85 is turned to the "on" position. The warming plate 42 will begin to heat and the "WARM" light 86 will show. The "push to brew" switch 88, and indicated as T2 in FIG. 10, which is on the side wall of the upper housing portion containing the water reservoir, is then depressed and the water in the reservoir 16 will begin to heat and the "brew" light 87 will show. If the brew switch has been accidentally turned on with no water in the reservoir, the plug 78 should be promptly disconnected from the electric outlet and the reservoir 16 should be allowed to cool and then water should be added to the reservoir. Plug 78 should then be plugged into the outlet again.
The thermostat T1 thermostatically controls the main unit and heats the water. The thermal valve T1 indicated in FIG. 10 in the bottom of the reservoir 16 opens and allows the heated water to start to drain and enter the spreader cover 44 which distributes the hot water evenly through the cover member 57 and into the filter support wall member 58. The hot water then passes through the small openings 60 onto the coffee grind within the paper filter 62. The coffee is then filtered and drips through the silk screen 68 which acts as a second filter and then passes into the glass carafe 20.
The main heating unit (not shown) and well known in the art will turn off automatically when the water has been heated to the proper temperature. The "brew" light 87 will go out but the "warm" light 86 will stay on which indicates that the warming unit 42 is still on. Sufficient time is allowed for brewing to be completed and all the hot water has filtered through the coffee grind.
Before the coffee is served, the carafe 20, with its basket and spreader assembly, is removed from the coffee maker. The basket-spreader assembly is removed from the carafe 20 and placed in the sink for cleaning up later. The coffee in the carafe 20 should be stirred before serving. The serving cover 69 is then placed on carafe 20 with its flange 70 within the neck of the carafe and the opening 71 is lined up with the pouring spout 72 of the carafe. After serving the coffee, the carafe is placed on the warming plate 42 to keep the coffee at serving temperature. When all the coffee has been served, the switch 85 is turned to "off" to disconnect the current.
If it is desired to immediately make another carafe of coffee, the electric cord 77 and plug 78 is kept in the wall outlet with the switch 85 turned to "off". The basket 19, spreader assembly and carafe should then be washed and rinsed before repeating the above described operation. When brewing one carafe of coffee immediately after another, cold water should be used in order to reset the thermostat.
In order to clean the coffee maker, it is unpluged and the warming plate is allowed to cool. The outside and base is cleaned with a damp cloth and then dried with a dry cloth. The coffee maker unit is not to be immersed in water. The carafe, basket, spreader and serving cover is cleaned in hot soapy water with a dish cloth and then thoroughly rinsed with clear water and permitted to dry. If a lime deposit forms in the reservoir because of the hardness of the water used, white distilled vinegar may be used for the cleaning process by pouring about ten ounces of the vinegar into the reservoir and adding about two cups of hot water and allow it to remain for about one half hour. The carafe is then placed on the warming unit 42 and the plug 78 is placed into the wall outlet and both switches 85 and 88 are turned to "ON" and the coffee maker is permitted to complete its cycle. The switch 85 is then turned off and solution is discarded. To rinse, the reservoir is filled with cold water to the ten cup level and the switches 85, 88 are turned to "ON" to cycle the coffee maker. If the coffee maker should begin to drip, a distilled vinegar solution should be used to clean it.
The front legs 81 and back legs 82 of the beverage maker are set inwardly from the front and rear of the device and are sufficiently high so that the bottom of the base of the unit is off the surface upon which the beverage maker is placed to permit air to circulate beneath the base to prevent excessive heat from the warming plate 42 from damaging any surface upon which the unit is placed and to aid in keeping a circulation of air beneath the warming plate 42.
While this device is primarily designed to make coffee, it can also be used to make tea, bouillon, and cocoa. The cocoa mix, or bouillon granules, tea leaves or tea bag may be placed in the serving carafe or in the basket 19 and used as heretofore described.
