INVENTOR ATTORNEY WIJTSE BEIJE SMITS, OF DIEMEN, KERHLAAN, NETHERLAND$.
ELECTRICAL TEA-HEATER.
Specification of Letters Patent.
Patented Oct. 28, 1919.
Application filed April 29, 1919. Serial No. 293,563.
To all whom it may concern:
Be it known that I, WIJTSE BEIJE SMITs, subject of the Netherlands, residing at Diemen, Kerhlaan, Netherlands, have invented a new and useful Electrical Tea-Heater; and I do hereby declare the following to be a full, clear, and eXact description of the same. 1
This invention relates to electrical de vices for heating liquids such as tea, coffee and the like. Hitherto it has been usual to employ for these purposes carbon filament lamps or ordinary resistance coils.
There is however the disadvantage with such heaters that a relatively small quantity of heat, for example, that produced by 100 watts has to be transmitted in a relatively short space of time, so that glow lamps are unsuitable because the heat transmission from the filament in a vacuum proceeds very slowly; while resistance coils are not desirable because for a voltage of say 220, it is necessary to use between 12 and 20 meters of wire for the quantity of heat it is desired to produce and such an installation is impracticable in the small space which is available for a tea heater.
The object of the present invention is to overcome the above mentioned difficulties and at the same time retain the illuminating efiect of a lamp, which is desirable in devices of this kind.
The present invention consists in an improved electrical device for heating liquids comprising the combination of an ordinary incandescent electric lamp and a resistance coil arranged around or closely adjacent the lamp and connected in series therewith.
The invention will now be described with reference to the accompanying drawings which illustrate one example of a device constructed in accordance with the invention and in which Figure 1 is an elevation of the complete heating device, and
Fig. 2 is a diagram showing the electrical circuit.
In carrying the invention into effect the apparatus comprises an electric incandescent lamp, preferably having a carbon filament, the exterior of the glass bulb of which is provided with a series of ribbed bars of glass or other suitable transparent medium and upon which the resistance wire 2 is wound. As will be seen in Fig. 2 the re sistance is connected in series with the filament 8 while the conductors a and 5 are connected in the usual manner in the lamp socket 6 with the filament and the resistance.
The voltage may be divided over the resistance and the lamp as desired. For instance there may be used a carbon wire lamp, adapted to be illuminated at 150 volts and having about 30 candle power with a consumption of about 100 watts in which case the %%g is about 0.65 Amps. In case the general voltage is 220 volts, 70 volts are kept at the disposal of the resistance wire, so that this wire has with a current intensity of 0.65 Amps, a capacity of 0.65 70:4t5 watts. Experiments have shown that the efiiciency of 45 watts in the conditions which are encountered when the device is used as a tea heater, have a far better effect than the 100 watts consumed by the carbon wire so that in this way efficiency is obtained without the difliculties mentioned above.
What I claim is:
An improved electrical device for heating liquids comprising the combination with an ordinary incandescent electric lamp of a resistance coil arranged around the lamp and connected in series therewith.
In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
WIJTSE BEIJE SMITS.
