ROBERT C. WALBERG, F NEW PRESTN, CONNECTICUT.
HEATER.
Application filed May 22, 1922. Serial No. 562,790.
. T0 all whom t may'ooncewt:
useful Improvements in Heaters, of which the following is a speciiication.
This invention relates to an electric water heater, the general object of the invention being to provide means for turning on the n current to heating coils when water is drawn from the heater and forshutting off the current when the iiow of water ceases.
Another object of the invention is to provide a plurality of spirally arranged water tubes for conductingthe water through the device and arranging the heating coils in the space formed by said tubes.
Another object of the invention is to enclose the tubes and heating coils in a casing formed in part of insulating material so as to prevent loss of heat and enable the heat from the coils to quickly heat the water in the tubes.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in theA appended claims.
In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a side view of the invention.
Figure 2 is a longitudinal sectional view.
Figure 3 is a section on line 3-3 of Figure 2.
Figure 4 is al section on line 4 4 of Fig ure 2.
Figure 5 is an elevation of one end of the device with the cover removed.
Figure 6 is a detail view showing the block 13 and the contact plates.
Figure 7 is a sectional view of the spring brush 11.
Figure 8 is a diagrammatic view of the circuits.
In these views 1 indicates a casing which may be formed in whole or in part of insulating material, said casing being preferably of cylindrical form. An inlet cap 2 is connected with one end of the casing and an outlet cap 3 is connected with the other end of the casing. A delivery pipe 4 leads from the cap 3 and a supply pipe 5 is connected with the reduced part 6 of the cap 2. This reduced part 6 has a valve seat 7 formed in its upper part to receive a spherical member 8 which is held to the seat by the cover part 9. A gate 10 is connected with the member 8 and acts to control the passage of water through the part- 6. A spring brush 11 is connected with the member 8 diametrically opposite the gate 10, said brush being adapted to engage with the contact plate 12 which is carried by an insulated block 13 which is seated on the part 6 and forms a chamber to rece-ive the brush 11. A spring 14 holds the brush out of engagement with the contact plate and the gate in a position closing the part of the cap. Then tliewater is permitted to flow through the part'G it will swing the gate forwardly, ius revolving the spherical member S and moving the brush into engagement with the contact plate 12. `The cover member 9 is electrically connected with a source of supply through the connections 15 anda terminal post 16 and the contact plate 12 has a terminal post 17 connected therewith which is connected by the conductor 18 with the terminal 19 passing through the casing and which is in electrical connection with the heating coils 2O in said casing. All of these coils are electrically connected together and are supported by the partition plates 21 in the casing which are provided with holes 22 to receive the coils. Spirally arranged tubes 23 are arranged in the casing adjacent the walls thereof, said tubes passing through holes 24 located in the partition plates, the holes in the partition plates being so arranged that the tubes form a. circular space in which are located the heating coils. The ends of the tubes pass through the ends of the casing so that the tubes are in communication with the caps and a deflecting cone 25 is placed on the inlet end of the casing for directing the water into the tubes.
From the above it will be seen that when a faucet on the delivery pipe 4 is opened, water will start to How through the device and this water will act upon the gate 10 to open the same, thus moving the brush into engagement with the contact plate 12 and so closing the circuit to the heating coils. This circuit may be provided with an ordinary switch 26 if desired. The water will flow into the cap 2 and through the tubes into y are of small dimensions the Water Will be heated much quicker than it Would if it would flow through the casing in a large stream.`
A cover is provided for enclosing the switch means, as. shown.
It. is thought from the foregoing descrip.- tion that the advantages and novel features of my invention' Will be readily apparent.
I desire it to be understood that I may make chan-ges in the construction and in the combination and arrangement of the several parts, provided that such changes fall Within the scope ot the appended claims.
that I claim is z-e 1. A device of the class described comprising an insulated casing, a plurality of spirally arranged tubes arranged adjacent the inner Walls thereof and having their ends passing through the ends of the casing, heating coils inthe casing, an electric circuit connected with the coils, caps connected With the ends of the easing, a discharge pipe connected with one cap, an inlet pipe arrange in the other cap, a gate connected With the inlet pipe and actuated by the Water passing into the pipe, a spherical member seated in the inlet pipe for rotatable movement and having the gate secured thereto, a brush carried by said member diametrically opposite the gate, a contact plate arranged to be engaged by the brush when the gate is moved by the Water passing through the inlet pipe and means for connecting said conta-ct plate and brush with the circuit as and for the purpose specified.
2. A heater of the class described comprising an insulated casing, spirally arranged tubesv therein having their ends passing through the ends of the casing, means for supplying a liquid to one end of the tubes, discharge means for the other ends of the tubes, heating coils Within the casing, means for supplying the same with current and partition plates in the casing having holes therein through which the coils and tubes pass and the tube plate holes being arranged so that the tubes form a circular space within which are disposed the coils.
In testimony whereof I a'lix my signature.
