ELECTRIC HOT-WATER HEATER.

Application led .Tanuary'l, 1928. Serial No. 246,959. i

This invention rela-testo new and useful device in the nature of an electric hot water heater using electricity as a medium for heating hot water, and is Vespecialy adapted for use in residences and the like, when a supplf)7 of hot water is desirable.

The obj ect of the invention is to provide an electric hot water heater of novel construction and arrangement of parts hereinafter more lo fully described, claimed and illustrated in' the accompanying drawing.

Fig. 1 illustrates my improved device as same would appear when in use, certain parts being shown in section.

Fig. 2 is an enlarged of the heater proper.

Fig. 3 is a schematic wiring diagram thereof. y

Fig. 4 is a central sectional view of the water supply valve as embodied in my imv proved device.

Fig. 5 is a perspective detail view of the valve proper.

Fig. 6 is a perspective detail view of the 25valve control member.

Fig. 7 is av fragmentary perspective view illustrating a further development of'my improved device.

f Fig. 8 is a fragmentary sectional view of Fig. 2 showing the modification of Fig. 7 applied thereto. f

As Vhere embodied my improved device comprises an electric heater consisting ofa housing 10, or shell, of tubular construction, and provided with feet 11, or supports secured thereto at the lower extremity thereof, and extended downwardly therefrom, as a vmeans of supporting the said heater. rlhe housing 10 is provided with a closed lower end 12, and a closed upper end 13. The coil 14, preferably of copper tubing is positioned in the housing 10, the lower portion of the coil 14 extends through an aperture formed in the lower portion of the housing 10. The upper portion 16 of the coil 14 extends through an aperture formed in the upper closed end 18. Y y i Y My improved device is particularly adapted to be attached to the usual or existing 'cold water pipe designated by the numeral 17 and which is provided with .the usual water faucet 18, positioned over the usual sink 19. The hot water pipe 17 is cut and the usual commercial T 20 is threadedly attached thereto.

l5 vertical sectional view the T 20 and is of hollow construction and The valve body 21 is threadedly attached to has formed therein intermediately a valve seat 22, formed tapered, adapted to receive the valve proper 28, which is provided with a tapered portion 24 and a central extended element 25 and radially extended lugs 26 adapted to'slidably engage in the enlarged bore 27 of the valvebody 21. The valve control member 28 is of tubular construction and is pro vided with a threaded portion 29 as a means of attaching the valve control member 28 to the valve body 21. The valve control member 28 is providedwith handle elements 30, or lugs, as a means of adjusting, or rotating the valve control member 28, for the purpose as hereinafter set forth. member 28 is provided with an axial lug ele ment 81 supported by the radial elements 32. The valve control member 28 is provided with a threaded .portion 33 adapted to receive the washer S4. The extremity 85 of the lower portion 15 of the coil 14 being formed flanged outwardly, so as to freely engage in the threaded portion 88 of the valve control meinber `28 and secured therein by the washer 36, suitable rubber washers 87 are positioned adacent to the flanged portion 35 of ther lower portion .15 of the coil 14 and adjacent to the washers 34 and 86 as a means of permitting the valve control member 28' to be freely rotated without the leakage of water. `The ex- The valve control p'ansionl spring 39 is positioned in thevalve body 21 as a means of ,holding the valve proper 23 in engagementl with or in contact with the lugelement 81 of the valve control member 28. The above described cpnstruction is such as will permit the valve proper 23 to be opened or closed by rotating the valve control member 28 as a means of supplying the desired quantity ofwater to the above mentioned heater.l

The upper portion 16 of the coil 14V is ex tended, preferably at the rear of the above mentioned sink 19 and has secured at its extremity the usual water faucet 40 positioned over the sink 19. l

an electric heater comprising the usual wire 41 suitably coiled so asto provide the required radiating surface is mounted on the usual insulated base 42 positioned at the Abottom of the above mentioned heater directly below the coil 14. The heating coil 41 is connected by the wire 43 to the battery 44, or any suitable convenient means of electric current and connected by means of the wire 45 to the coils 46 of the usual rheostat mounted on the panel 47, which may be secured to the wall to the Contact 48 and positioned or located adjacent the valve control member 28. The movable contact lever 49 of the above mentioned rheostat is connected by means of the Wire 50 to the above mentioned battery all. rlhe ahove described construction is such as will permit any desired amount of electric current to be supplied to the heating coil all as is required to heat the water in the coil 11i. rllhe electric light bulb 5l, preferably colored red is mounted in the usual socket 52 and is connected by means of the Wires 53 and to the auxiliary rheostat Contact lever 49 insulated as at im from the lever i9 and to the battery 56, which is connected by means of the Wire 55 to the coils i6 of the said rheostat a moans of lighting the electric light bulb 5l so as to provide a red Warning li ght when the heater is in operation. in electric light bulb 57 of usual White transparent glass is mounted in the socket 58 and is connected by means of the Wires 59 and GO #to the rheoszad contact lever 49 and to the battery (il, which is connected point 63 adapted to be engaged by the rheostat lever fi-9 by means of the wire G2. The latter described construction is such as will provide a White light when the heater is not in operation, It should be understood that the

sockets

52 and 58 are mount` ed on the panel 47.

In Fig. 7 of the accompanying drawing- I have shown the valve control member 2S having formed or cut therein, teeth adapted to mesh with the segment gear G5 integral with or secured to the Contact lever iQ ofv the said rheostat. The above described construction is such as Will permit the electric current supplied to the heating coil il to be automatically increased or decreased When the valve proper 23 is opened or closed. An extension 65 from the gear 64 has atits end another gear G6 meshing;` with a rack 67 at the top of rod G8 slidably guided along the side of housing,l l0 down to the bottom thereof and then formed with ll-bend 69. The free arm of this U-bend extends through an aperture in base l2 and connects to base Li201 the heating` unit. The heating unit is slidable on guide 70. Upon turningl member 28 to adjust valve or further from the Water coils ll.

23 and arm 49, the gear 66 Will also be turned moving rack 67 and rod GS, which will raise or lower the heating unit so as to be nearer As the valve 23 is opened, the heating unit Will move closer to the Water coils.

I,While I have above described the preferred form, construction and arrangement of the several elements employed, it Will be under- `stood that the device is nevertheless susceptible of considerable modification therein and I therefore reserve the privileg'ge of resorting 'to all such changes as may be fairly embodied Within the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim new and desire to protect by Letters Patent of the Unitec States is as follows l.' An electric hot Water heater, compris1- ing a housing with a Water coil, guides connected with theinterior of the housing, a heating unit slidably mounted on the guides, and a. rod attached to the heatingy unit and extended from the housing and arranged upon motion for raising or lowering the heating unit so as Vto be nearer or further from the Water coil.

2. An electric hot water heater, comprising a housing with a water coil, guides connected with the interior of the housing, a heating` unit slidably mounted on the guides, a rod attached to the heating unit and e1;- tended from the housing and arranged upon motion for raising` or lowering the heating unit so aste be nearer or further from the Water coil, and a means for moving` and holding the rod in various positions.

3. In an electric hot Water heater, guides mounted on the heater, a heating unit movably mounted on the guides, and a rod attached to the heating unit and extended from the heater, and arranged for raising and lowering the heating unit, upon motion so as to be nearer or farther 'from a. Water coil of the said heater.

In testimony Tvhereof I have affixed my signature.
