Specification of Letters Patent.
Patented Apr. 3, 1917.
Application filed October 14, 1916. Serial No. 125,676.
To all whom it may concern.
Be it known that I, EMIL STRANszKY, a citizen of the United States, residing at New York. New Yorkcounty, and State of New York, have invented and discovered certain new and useful Improvements in Electric Water-Heaters. of which the following is a specification.
The present invention relates to electric water heaters and consists in the combinations and arrangements of parts hereinafter described and particularly set forth in the accompanying claims.
The invention has for its purpose to provide an electric heater for water systems, wherein the heated. water is adapted for use at a distant station, and in which a local supply of water is maintained constantly heated and for use at the immediate heating station.
The invention has for its further purpose to construct an electric water heater having a common control for the circuit closer and flow of water, and with a variable control for the local supply; and in which the apparatus as a whole constitutes a unitary structure adapted to be readily set up in present installed water supply systems.
The invention is shown by way of illustration in the accompanying drawings, wherein Figure 1 is a central sectional view of the heater, with the wiring circuit in diagram.
Fig. 2 a horizontal sectional View taken on the line 22 of Fig. 1, and
Fig. 3 a similar view taken on the line 3-3 thereof.
Referring to the construction in detail the apparatus consists ofa cylindrical vessel 1 having a section 5 detachably mounted thereon, and provided with a pair of head plates 6 and 7 forming a water receiving chamber 8, a water discharging chamber 9, and an intermediate air heating chamber 9'. A pipe 8 connects the receiving chamber 8 with the source of water supply.
A partition plate 10 is mounted in the cylinder section 5 to form an auxiliary hot water supply and discharging chamber 11 that communicates with the main discharging chamber 9 through the apertures 12 and 13 formed in said partition 10, as shown in Fig. 2. Said openings 12 and 13 are of relatively difi'erent sizes to the end that difierent flows of water may enter said auxiliary discharging chamber, to be further described.
A plurality of tubes 14 are located in the heating chamber 9 and are secured at their respective ends to the head plates 6 and 7 and each of said tubes is provided with a covering of insulation 15, of any suitable material. An electrical resistance coil 16 is wound on the insulation of each tube and the several resistance coils are connected in parallel with the circuit conductors 17 and 18 from the source of electrical energy 19; and a condenser 20 is provided to prevent sparking at the switch, as will be understood. 4
A water discharging pipe 21 leads from the main water chamber 9 to a distant station, and the flow of Water therethrough is controlled by a valve 22 that is mounted on the shaft or stem 23 journaled in suitable bearings in the cylinder section 5 and the partition plate 10. The rotary valve 22 is formed with an annular flange 24 fitting closely against the inner surface of the wall 5, and said flange is constructed with an in-set portion 25 forming an opening adapted to register with the pipe 21. An aperture 26 is formed in the disk portion of the valve to register with either of the apertures 12 or 1-3 of the partition plate 10 and govern the flow of water into the auxiliary chamber 11; and a faucet 27 is provided for drawing off the heated water from said chamber, as shown. The circuit closing device for the apparatus consists of a block of insulation 28 suitably secured to an extended portion 29 of the cylinder part 5, and. a plurality of pins or contact members 30 are secured in the block 28 and are connected in pairs with the conductor wires 17 and 18, as indicated at 31, whereby a circuit will be closed through all the resistance coils accordingly as the water is discharged through either the pipe 21, or into the chamber 11 through the openings 12 or 13.
The switch per se consists of a contact piece 32 that is mounted on the square and tubular stem 33, having loose engagement with the squared end 34: of the valve stem 28, and a knob or hand-turning piece 35 is provided for turning the switch to close a circuit through the coils and regulate the flow of hot water. The hand-turning piece chamber, an outlet 35 has slight freedom bf axial movement,
from the spirit of my invention, and therefore l do not wish to be limited to those features except as required by the claims.
Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:
l. lln an electric water heater, the combination of a vessel having a water receiving chamber. and a water discharging chamber, a partition within the water discharging chamber providing an auxiliary discharging ch-amber communicating with the main discharging chamber, a water heating tube in the vessel connecting said water receiving and discharging chambers respectively, a coil of resistance wire around said tube, a circuit closing device for the resistance coil, a water discharge pipe leading from the main discharging chamber, an outlet pipe for said auxiliary water chamber, a rotatable valve for said discharge pipe and the passage to the auxiliary discharging chamber, and a common controlling device for said valve and the circuit closer, substantially as set liorth.
2 in an electric water heater, the combination of a vessel having a water receiving chamber and a water discharging chamber, a partition in said discharging chamber providing an auxiliary water discharging chamber communicating with the main discharging pipe for said auxiliary discharging chamber, a water heating tube in the vessel connecting said receiving and discharging chambers respectively, a coil of resistance wire around said tube, a circuit closing devicei'or the resistance coil, a water discharge pipe leading from the main discharging chamber, a rotatable valve comprising a flanged plate mounted in said main discharging chamber controlling the communication with said auxiliary chamber and having an inset tlange portion adapted to register with said discharge pipe, and a common controlling device for said valve and the circuit closer, substantially as set forth.
5. ln electric water heater, the combination of a vessel having a water receiving chamber water dischargingchamber, a partition in said discharging chamber proviu eg an aux liary water discharging cham-= having commw catlng nannies nation of a vessel havin a water receiving chamber and a water disc arging chamber, a partition plate in said discharging chamber providing an auxiliary discharging chamber, saidpartition plate having apertures therein of diderent sites, a heating tube in the vemel connecting said water receiving and discharging chambers respectively, a coil oi resistance wire around said tube, circuit closing device for the resistance cell, a water discharge pipe leading 'l'rom the main charging chamber, a rotatable valve hav mg an opening for registering with said discharge pipe, and an aperture adapted to reg ister with said partition apemures respec tively, and a coon controlling, device for said valve and the circuit closer, mibstan tially as set orth,
