WILLIAM DOHERTY, OF WEST PHILADELPHIA, PENNSYLVANIA.
AIR-HEATING PLANT.
. Application filed May 21,
This invention relates to an electric furnace, the general object of the invention being to provide a housing thoroughly covered with non-conducting material and having therein a large electric heating coil which is suitably connected with a-source of supply for heating the air in the interior of the device, with means for conducting the heated air to the point of use.
Another object of the invention is to provide means forsupporting the coil at adacent the center of the housing by a tubular member which is supported by a tubular base of'non-conducting material, these mem- -bers forming a thecoil.
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 the appended claim.
In describing my invention in detail, ref erence will be had to the accompanying drawings wherein like characters denote like or correspondin partsthroughout the several views, and in which:
passage for the conductors of Figure 1 is a vertical sectional view.
through the improved furnace.
Figure 2 is a section on line 22 of Figure 1.
Figure 3 is a section on line 3-3 of Figure 1.
' Figure 4: is a diagrammatic view of the circuits.
In these views, 1 indicates the base of the housing which is formed of cement or the like, 2 indicates the sidewalls which are formed of inner and outer layers 3 of asbestos orthe like with an inner reinforcing member 4 of metal or the like and 5 indicates the dome-shaped top of the housing. The housing is provided with a hinged door 6 so that access can be had to the interior parts thereof and in its lower part, it is provided with air inlet ports 7 and pipes 8 are connected With its upper part for conductin the heated air to the pointsof use. Metal and 9 hold the layers 3 in place.
' A tubular base 10 of porcelain or the 1926. Serial No. 110,736.
like is fastened to the baseof the furnace and a tubular member 11, preferably of brass, is carried by the base 10. A cup-. shaped member 12 of porcelain or the like is supported by the member 11and this member 12is grooved to receive the coil 13 which forms the heating element; of the furnace. The ends of the coil are connected by the wires 14 with the contact strips15 carried by thebase 10 and these strips are electrically connected with the plug 16 which in turn is connected with the main switch 17 by the conductors 18, these conductors passing through a hole 19 formed-in the housing. I also provide a switch 20 in each room or in any desired room for controlling the circuit of the heating element, two of these switches being shown in Figure 4: in addition to the main switch 17, all three switches being connected with the battery B or other source of supply.
From the foregoing, it will be seen that I have produced a simple and efficient electric furnace which can be manufactured to sell at low cost and one which is not likely to get out of order, due to its strong construction. The parts are all accessible through the large door so that repairs can be easily made. l
It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.
I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that suchchanges fall with 'in the scope of the appended claim.
WILLIAM'DOEIERTY.
