EPECIFICATION forming part of Letters Patent No. 386,071, dated July 10, 1888.

Application filed July 23, ISSS. Serial No. 172,437. (No model.)

In Fig. 5 the half-ring d is plus and the halfring d minus when the armatures are as shown in that figure, and the current through the line is fromf tof; but when the armatures are moved through ninety degrees the halfring d becomes minus and (1 plus; but as the brushes ff have changed contact with the half-rings-that is,fis in contact with d and f with dthe current over the line f is as before-that is, from f to f. On the next quarter of the revolutionthat is, when the armatures have been moved the second ninety degrees (or one hundred and eighty degrees from their position shown in Fig. 5)the halfring d will be plus and the half-ring d will be minus; but the current will nevertheless be fromftof, becausefis then in contact with d and f with d. On the next quarter of the revolution the half-rings d d. again change their polarity, (I being minus and d plus; but the current is the same as before, forfis then in contact with d andf with d. In this way there are two pairs of currents of the same polaritythat is, in the same directionsent through the wire at each revolution of the armatures, and the purpose of this arrangement of the half-rings d d and brushes ff is to cause a bell-hammer arranged between two bells and actuated by the currents generated by my device to strike two blows upon one bell, then two upon the other, for each revolution of the armatures B B.

In Fig. 13 I show two bells, 1 and 2, arranged with a bell-hammer, 3, between them, and this is a convenient arrangement of the hammer and the two bells, as will be readily understood without furtherdescription. When simple alternate currents are required, the half-rings d d are not necessary;

but this arrangement, whereby I get currents in pairs, is an important feature of my invention.

Fig. 11 is a diagram illustrating one of my magnets with six poles, and Fig. 12 with eight poles; and from the drawings it will be clear to all skilled in this art how to multiply the poles to any desired extent. In Fig. 11 no advantage is derived from using a double armature, and I have therefore indicated an ordinary armature; but while I have shown my magnets as adapted to induce a current in the coil of an armature I do not of course limit myself to such use.

One of the chief advantages of my new apparatus is that multiplying-gear can be dispensed with; for although I have shown such gear in Fig. 1, that is solely because I wished to indicate the medical use of my apparatus; but with my double armature each revolution will give four currents with a four-pole magnet, eight currents with an eight-pole magnet, and so on, for each revolution of the armature, and consequently no multiplying-gear is needed for many uses of my apparatus. This is a practical matter of considerable consequence, as it greatly lessens the expense of construction.

What I claim as my invention is-- 1. The double armature above described, composed of the two cores and the two coils, the cores being held together back to back, but magnetically insulated, substantially as shown.

2. In combination, the double armature B B and its two coils, the magnets A A, &c., and the electrodes (2 d and f f, whereby the currents are sent in pairs over the line, as set forth.
