ELECTRIC HEATER.
Specification of Letters Patent.
Patented March 12, 1907.
Application tiled January 3, 1906. Serial No. 294,388.l
in Philadelphia, in the county of Philadel-A phia and State of Pennsylvania, have invented an Electric Heater, of which the following is a specification.
This invention is an improvementin electric heaters, and relates more especially to that class which are adapted for heating water and circulating the same for the purpose of heating cars and other compartments.
The primary object of the invention is to provide a simple and eflicient electric heater for use in connection with a water tank or boiler, whereby the water in such tank or boiler may be quickly heated and 'caused to e circulate through the usual water-pipes emp the apparatus, all as hereinafter fully deployed for increasing the amount of heatradiating surface.
A further object of the invention is to so construct the electric heater and tank or boiler as to produce a complete water-heating apparatus for hot-water heating systems, which is compact in construction, economical in use, and in which the parts are so arranged and connected that they may be conveniently examined and readily repaired or renewed, if necessary.
With these general objects in view the invention consists in the combination, with a water tank or boller having inlet and outlet openings to whic the circulating-pipes are connected, of an electric heating device com'- prising a plurality of closed metal tubes suspended in the boiler and containing the resistance-wires prop'erly insulated therefrom.
The invention further consists in the particular construction of the. parts constituting scribed, and more specifically set forth in the appended claims.
In the accompanying drawing, which 'forms a part of this specification, Figure 1 is a vertical longitudinal sectional view of an electric heater or water-heating apparatusA constructed in accordance with our invention. Fig. 2 is a top plan view with the covering-plate and electric heating devices removed. Figl 3 is a similar view, the electric heating devices being shown in position in the water tank oi' boiler. Fig. 4 is a detail view of the covering-plate. Fig. 5 is a transverse sectional view through one of the electric heating devices. Fig. 6 is a vertical sectional view, enlarged, through one end of the tank or boiler and including one of the heating devices. Fig. 7 is an elevation of the rear or discharge end of the apparatus.`
Fig. 8 is a similar view of the front or intake -end of the boiler or apparatus.
vLike-letters and numerals of reference indicate like parts in all the views of the drawing.
In carrying out our invention we employ in the first instance a water tank or boiler c, which is substantially rectangular in crosssection and is provided at one end with an inlet-pipe L and at its other end with an outlet-pipe h, the former enterin the tank or boiler at the bottom thereof, w lle the outlet is located at the top, and where said pipes connect with the boiler the'openings therefor are formed in bosses B and A, respectively. This tank or boiler is disposed at an inclination longitudinally, as shown in Fig. 1, for -which purpose there is formed at one end, the outlet end, le s or feet F. By thus inclining the tank or oiler upwardly from the intake to the outlet it greatl accelerates the circulation by inducing a ow of the heated water 'or fluid' tothe outlet. This tank or-boiler may be constructed in any suitable manner; but inthe present instance the ytop P is attached to lateral flanges E-of the body b means of screws k, with an ordinary pac ingv l interposed to provide a water-tight joint.
Located in .he of tubes d, which are adapted to' contain the electric 'heating devices hereinafter described, said tubes being preferably suspended from the top e of the tank, for which purpose the latter is provided With ltoles into which the open ends of .the tubes d are threaded, the connection between the tubes and top of the tank being such as to prevent leakage. By this arrangement the tubes are let into the water or other fluid contained in the tank or boiler, so that the water or fluid may circulate around the same, and as they open out through the top of the boiler the heating medium may be conveniently placed therein. y
In each of the suspended tubes d there is located an electric heating device or rheostat, comprising in' the present instance the resisttank or boiler c are a series IOO IOS
lcoils, which are connected to form a continug ance wires or coils s, which are wound upon i rods p, of porcelain or other non-conducting material, said rods being held between opi posite plates g and t, of slate or other non-coni ducting material, one of said plates, as t, bel ing adapted to fit within the tube d, while the Vl other plate, as g, is adapted to cover said I' tube and is preferably rectangular in shape, (see Fig. 3,) being secured in place by screws i The under side of the plate or cover g is provided with a boss which fits snugly within 1 the open end of the tube d, and on said under side of the plate is placed a lining of asbestos, l as 7, for the purpose of cushioning the leatl ing device and also for retaining the heat I within the tube, so that it may be utilized in l heating the water. The porcelain rods p are let into recesses in the plates t and g, and the parts are held firmly together by means of a bolt a, as shown. In each heating device or rheostat there are preferably four resistanceous circuit, the wire extending from the first to the second coil through the plate t, from the second to the third coil through the plate g, and from the third to the fourth through the plate t, the several heating devices or rheostats being connected in series, as shown in Fig. 3, for which purpose the usual blocks or connectors m are provided. The electricity from a suitable source of supply is conducted by the wires b b.
In order to protect the electric heating devices or electrical connections at the upper end thereof,v a `covering-plate a is removably secured |to the tank or boiler and at one end is provided with bushings o, of porcelain or othernon-conducting material, throughwhich pass the conducting wires b to and from the series of electric heating devices or rh'eostats.
The operation of the apparatus will be readily understood. As the current of electricity being turned into the rheostats or heating devices the resistance wires or coils s thereof will be heated, which will result in heating the tubes d, and the latter being susl ended in the Water of the boiler or tankavill iieat such water and cause it to circulate through the pipes h and i and intermediate connections, such circulation being accelerated by the inclination of the boiler, as hereinbefore pointed out.
By making up the electric heating device of a series of independent devices and locating the latter in separate tubes depending into the water tank or boiler a maximum amount of heating-surface is presented for quickly heating the water and causing a rapid circulation of the same. Also by this arrangement the entire heating device can beY readily and conveniently examined and repaired.
In case any one of the individual electric heating devices contained in the tubes d is found to be injured or out of order such individual heating device can be readily removed and repaired or replaced by a new one. The particular construction of the individual electric heating devices permits them to be rewound very quickly, in which operation it is only necessary to loosen the bolt n sufliciently to allow the rods p' to be removed, re* Wound, and replaced one at a time.
Though we have described the apparatus as used for the purpose of heating water for hot-water heating Systems, it is obvious that the same could be used for heating other liquids and, in fact, for any purpose where it is desired that a maximum amount of heatingsurface be provided.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
