BachekVs Naw or Improved EUctromagnetic Therapeyutic Apparatus. magnet to and tlnougL. tlie other, and therefore it is obvious that hv movino' one magnet relatively to the other, so that a direct line between their opposed poles will pass through the body of the patient, such part of the patient will be traversed by the greatest number of direct axial lines of force without the magnets actually contacting with the natient. One maimer of treatment is indicafed in l-’ig. 4 in wliieli the magnets are pJaced at opposite sides of a room and the patient seated in the chair there etween will be subjected to the ac.tion of the magnetic current flowing directh' irom magnet A to magnet Ah as indicated in the drawings. It will be seen that, by my apparatus the lines of force developed by the electromagnet A, for example can be concentrated or prolonged in the direction of the magnet A^ and thus giving an definitive direction enabling the onerator to certainly control and direct their application to the patient, and this is the principal feature of the invention, and I do nof restrict myself to the employment of a second electromagnet A^ for the purpose of elongating or directing the magne,tic field or ^ines 0 bice generated by magnet A. Any other device which will accomplish the desired object may be substituted for tlie magnet A^ within the scope of my invention. Ihe possibility of varying and localizing the aimlication of the magnetic currents by varying the relative nositions of the magneis will be obvious. In Iig. 5 1 have indicated a preferred construction of the magnet in that the niaguet is preferably wound in a fiat wide annular cofi or ring, which is divided into sections connected with contacts n, any one of wlTicli can be brought into electrical communication with binding post cd by the switch-arm ed. The other terminals of the coils are all connected to a common terminal fif, and therefore by shifting swfitch more or less of the magnefic coils are cut into the circuit, and consequently greater or less magnetic force is generated by the magnet, while the same effect could bte realized by the introduction of a rheostat in the circuit; this construction of the magnet economizes the power and is more compact and desirable than a rheostat, particularly when the apparatus is made in portable form and operated by batteries. In Fig 5 a core A^ is indicated in the magnet which core should be laminated when used; but I do not restrict myself to the employment of cored magne:ts. Having now particularly described and ascertained the nature of mv invention and in what manner the same is to be performed I declare that whaf I claim is : 1. In an electromagnetic therapeutic apparatus, an electromagnet and means for prolonging the lines of force generated by said magnet and giving direction thereto substantially as described. 2. An electromagnetic therapeutic apparatus comprising one electromagnet, means mechanically disconnected from said electromagnet for prolonging and directing the line of force generated thereby and means for varying the strength of the magnetic field substantially as described. 3. In an electromagnetic therapeutic apparatus two magnets arranged in series mechanically disconnected but for the purpose and substantially as described. 4. In an electromagnetic therapeutic apparatus two mechanically discon¬ nected electro-magnets arranged in series and means for energizing the magnets substantially as described. 5. In an electromagnetic therapeutic apparatus two electromagnets arranged in series and an interrupter substantially as described. (). In an electromagnetic therapeutic apparatus, an electromagnet, and a second magnet in series therewith, said magnets being mechanically discon¬ nected but relatively adjustable. 7.
