ELECTRIC LIQUID-HEATER.
Specification of Letters Patent.
Patented Jan. 4:,
Application filed March 6, 1909. Serial No. 481,835.
To all whom it may concern:
Be it known that I, ()scan H. F moss, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Electric Liquid- Heaters, of which the following is a specification.
The object of the present invention is to provide an electric fluid-heater which may be made portable and in which a given amount of fluid may be very rapidly heated entirely separate from the main body or supply reservoir, and which will be simple in construction, convenient in operation, and not liable to get out of order.
\Yith these ends in view my invention consists in the details of construction and combination of elements hereinafter set forth, and then specifically designated by the claims.
In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction and operation in detail, referring by number to the accompanying drawing, forming a part of this specification, and in which 3 The figure is 'a central vertical section of my apparatus. i
In referring to the drawing, I have shown a reservoir or supply tank which may be of any desired size, shape and proportions. A heating reservoir or chamber 3 is located below the bottom of the reservoir 1 in which the fluid from the reservoir is heated. A pipe or tube 2 screw-threaded on both ends connects the bottom of the heating-chamher 3 with the bottom of supply reservoir 1 by means of a screw-threaded nut 9 whici forces downon the washer 1O forcing the bottom ZOfthG supply reservoir 1 down upon the packing'ring 11 and the flange 12 making a water tight connection, the ipe 2 making a free passage'for the hqui. from the supply reservoir 1 to the bottom of the heating-chamber 3. A vent-pipe 5 is shown connecting to the top of the heating-chamber 3 and extending upward to a point above the top of the reservoir 1. A stop-cock 4 is shown connecting to the vent-pipe 5 at a oint above the bottom of the reservoir 1 and 1s the means by which the heated liquid is drawn off from the heatin -chamber 3. The heating-element consists o? a single layer of naked high-resistance wire 6, so wound that the continuous turns of the wire out contact with each other so as to prevent short-cireuiting. The ends of the resistance-- Wire; 6 are connected or anchored to two clamps 8 shown at each end of the heating coil which are insulated from the walls of the heating-chamber by means of the insulation 7. The insulation 7 consists of a thin layer of a high-resistance material such as sheet mica, which will not materially interfere with the passage of the heatfrom the coil to the walls of the chamber An ordinary electric light 13 is connected in multiple with the heating-coil (3 by wires it) which lead from the lamp l3 and connect to each oi the clamps or binding-posts 8. means of wires 15, current is conducted to the heating coil 6. A switch 14 is inserted in circuit with one of the wires 15 and completes or opens the circuit which conducts the current for heating the coil 6.
The operation of this apparatus will thei, be as follows: The reservoir 1 is first. fillewith water or such iinid that is required to be heated, which flows by gravity d wn the pipe 2- filling the heating-chamber 3 and then seeks its level in the vent-pipe The current is then turned on by means of the switch 14, heating the coil 6 and lio'hting the lamp i3 apprising the user that the apparatus is in operation. In a short 5; ace of time, which will be in proportion to the size of the heating-chamber 3 and theamount of current consumed by the coil 6 the fluid in the chamber 3 will begin to boil. By means of the stop-cock e} on the vent-pipe 5 the heated liquid can be drawn oil the heating-chamber 3 and will be replaced by" an equal amount of cold from the reservoir 1 which can in the same space of time be heated and drawn likewise from the stop cock 4. The top of the heating-clniuiber 3 out of communication with the reservoir 1, the vent-pipe 5 heating-chamberS and the stopcock i: connecting to the vent-pipe 5 at a point above the bottom of reservoir 1 form the main features of this invention. It is evident that if the top of the heating-chamber 3 was 1;
connected to or in any way connnunicated with the reservoir 'l the steam which would be generated in the heatingclianiber would naturally rise to the top and discharge and.
condense into the reservoir 1. The object of i.
having the heating-ehamber out of any communication with the reservoir 1 is to confine leading from the top of the entire heating energy generated by the heating-coil 6 to the 'l'lrkl in the heatingchamber 3. If any steam could escape throi i any connection to the reservoir 1 5 the heating energy of the steam would be taken the cooler liquicl in the reservoir which would greatly lower the efficiency of this apparatus.
it is 015 the very essence of this invention that th: heating-chambershoulclbe connected to atmosphere, by means of a ventpipe, for
the purpose off relieving the pressure Which would he gei'ieretecl. in the heating-chamber viclent that if the vent-pipe Was not the liquid when boiling would earn, which would rise to the top GIQUlLLZi S "ChQ lbQl 3 and back the o k 'Wll'lCll would. en-
7 ply the heatingchmnber 3 and pro- (luce excessive heating of the heutiz'lg-hhainher and heating-element 6, and on pening the stop-cocla: st ewn, instead of liquid voultl llow therefrom. the top of the heating chamber 3 as not connected to atmosphere by means Or the vent-pipe 5 this apparatus would he impracticable as the heating-chainher we 1e contain sir ml. the fluid could not readily now down in o the heating-chamber 3 on being filled for the ii llIlQ. The stop- 39 cool; being connected to the vent-pipe 5 at a, point shove the bottom the reservoir 1 is to produce means by which a portion of the may be retained in the bottom of the reservoir 1 so than the heating-chamber 3 may contain liquicl in case by neglect the operator would leave the current turned on when the liquid was down to the level of the stop-cool: 4t.
Many variations may be made in the form of the device from that here shown Wit out l. The
