' INDUCTION-COIL.
' Specification of Letters Patent.
Patented Feb. 13.,
Application fil ed November 15, 1904. Serial No. 282,890
To (all whom it may concern: I
Be it known that 1, JOHN SPLrrooRF, .a citizen of the United States. residing at New York cit in the county of New York and State of New York, have invented a new and useiui Improvement in Induct1on-Coils, 'ofing of the soft iron core. In all electromagnetic coils the very rapid magnetization and demagnetization of the iron core causes the ircnto become uite hot, and this heat is detrimental to t einsulation used between the coils as well as impairs the efliciency of the apparatus.
Latte-in my object by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a vertical section of anordinary Fig. 2 is a horizontal section of the same. Fig. 3 is a vertical section of an enlarged iron core separated from the coil, showmg a ertures extending through the iron; and ig. 4 is a top view of Fig. 3.
Similar numbers refer to similar parts throughout the several views.
In Fig; 1 the numeral 1 represents a soft iron core supported by the square frames 10. 2 is an iron armature'rigidly attached to the flat spring 11, which is supported by the bearing 15. 3 represents a thumb-screw with a jam-nut capable of adjustment upon the frame '16. fl represents the contactpoint between the sprlng 11 and the thumbscrew 3. 6 indicates a secondary windin of 7 indicates the primary win ing ct coarse wire, separatel'roin the core 1 and the primary winding 6 by the insulating ma- 12 represents an on space between the core 1 and the insu ating material 8, and 9 represents apertures through the frames 10, connecting the open space 12 with the external atmosphere.
In Fig. 3, '14 is an enlarged View of an iron core, showing the apertures 13 extending throughits length to allow the free passage of theatmosphere.
In 4, 13 and indicate the apertures extending through the iron core 14. r
In ordinary induction-coilsone end of the primary coil 7 is connected Withthe spring 11 at the bearing 15 and the-other end to one pole of the source of electricity, while the second pole is connected with the thumbscrew 3' by means of the bearing 16. i V hen the s ring, 11 makes a contact with the thum screw 3 at the point 4, the current of electricity passes through the primary coil 7. and magnetizes the iron core 1. The
moment this core lis magnetized the arma- I ture 2 .is attracted toward the core and the contact at 4 is broken.
In breaking the contact at 4 the electric circuit is'disrupted,' then the iron "core loses its magnetism, and the spring 1.1 flies back until it meets the thumbscrew 3 and closes the contact at 4. This operation is repeated very rapidly, and the I rapid magnetization and. demagnetization of the core causes the iron in the core to become hot and injurious to the coil. By .means of my invention 1. cause a free circulation of air about and through the core, which eliminates the heat and keeps the core c0ol, thus venting any injury to the insulation.
