MOSES c. FARMER, OF nnwrohgi, RHODE ISLAND,
ELECTRO-MAGNETIC HEATlNG APPARATUS,
SPECIFICATION forming part of Letters Patent No. 3.23 51 dated August 4 1885 Application filed March 14, 1885. (No mhdeL) To all whom it may concern:
Be it known that I, Mosns G. FARMER, a citizen of the United States, and a resident of Newport, in the county of Newport and State of Rhode Island, have invented certain new and useful Improvements in Electro-Magnet-ic Heating Apparatus, of which the following is a specification.
It is well known that certain changes of the magnetic conditions of an iron body are attended with the development of heat more or less intense, according to the rapidity and violence of the changes. I have found that if an alternating electric current be passed through a coil of insulated wire surrounding an iron core of somewhat greater length than the coil a marked degree of heat is developed in the core, greatest at its ends and diminishing toward its center. To utilize and to apply to general purpose this method of developing heat is the object of my present invention. I accordingly combine with an iron bar or simi lar body adapted to radiate the heat developed at and near its ends a large coil of low electrical resistance, through which I pass the current from an alternating-current machine. By this means I am enabled to convert power and electrical energy into heat in a way that for a great many purposes is extremely desirable and useful.
I have also devised certain forms of apparatus with a view to the better radiation and application of the heat. For example, I form the core of a number of plates, between which are spaces at the ends, through uhich a circulation of air is induced by the heat; or, if the heat is to be applied to a special purpose, such as heating water, I introduce the poles of the core into the vessel for containing the water, enlarging the poles or attaching some form of plate to them in order to obtain a greater radiating-surface.
I will describe more in detail these several features by reference to the accompanying drawings.
Figure 1 is a side view and part section of a. simple form of heater. Fig. 2 is an end View, and Fig. 3 a top or plan view, of the same. Fig. 4 is a side view of a modified form.
Fig. 5 s i p 1 tn, and Fig. 6 apart section, of a device fQl 1181; ing water and other fluids.
A g a fis a core composed of a given n mber of lrOIl' plates, a portion of which are of the full leng h of the core, and the remainder a e m orter, so that when made up into a b n r-spaces will be formed between the larg plates at the end of the core.
B 18 the C0 ade in the ordinary way. It should e of paratively low electrical resistance, n Should be of such length as to strongly magn the core with a given current. It may als be desirable to insulate the wire wlth s tance capable of with- St n mg Wlbhoflt l y a considerable heat.
The relative sizes of the coil and core may 6 be g y Varied: gh due regard should be had to securing the b t ti conditions. The core should be however' t, l t, double the length of coil, a d it may b more,
It is not essential that it S ould be straight. 0
The form shown in Fig. 4 may be desimme in some cases, and this and man th forms may be used with the same resqlt In some cases it may be ady m to bring the poles of the core into 511 m; t t;
with the substance upon which t heat is to act. For example, a device for bgili water or other fluid is shown in Figs. 5 a The form of core shown in Fig. 4 is hen used, the
ends of the cores being projected int, the 8O sel 0, preferably through the bottom and diating-plates D- are secured to the of the poles. With this device but a fi utes suffice to raise alarge volume of xv to the boiling-point with an alternating cu of considerable strength.
The means by which I propose to devc heat and which I have now described are many respects economical and in many 1, stances exceedingly desirable. the devices described I use an ordinary form of alternating-current machine, by which I avoid the necessity of using special devices for reversing the current or for producing the changes of current necessary for producing the 9 5 requisite changes in magnetism in the core.
