Definitions

  • Figure X is a plan view of machine with my improvements, having the covers removed.
  • Fig. X is a vertical longitudinal section of the same.
  • Fig. X" is an inverted plan, showing the connections of the different circuits.
  • Fig. Xmcx hibits a modification ofthe vibrating arniaturewhich constitutes one of the features of my invention.
  • Fig. XW is a face View of a movable hanimerhcad or piece to be used on the vibrating armature.
  • My 'invention consists, first, in intcrposing a helix into the primary circuit of au electro magnetic machine, in addition to the helix used for the principal -prirnary circuit, said additional helix'being for the purpose of re ducing the power of the induced currents by its oice ol reducing the primary current, by acting as a resisting medium to the same.
  • My invention further consists in a point for connection with spring to close the batterycircuit, so arranged that the alternate connection by the vibrating spring can be changed to apermanent connection ofsupportto shorten the spring, and so vary, in a greater degree, the rapidity or slowness of the vibrations or oscillations of said spring.
  • My invention consists, further, in having three or more coils of three or more different lengths and thicknesses of insulated wire with an electro magnet, and with movable magnet or a movable closed circuit, as a power-ad juster, so as to have a more desirable varia tion ofthe qualities ofthe currents developed.
  • My invention also consists of a method of supporting the helix by clasping the coils of thicker wires at or near one end of said helix, thus providing a convenient and proper support of c0ils,whose electric powers are varied by a movable closed circuit.
  • diagram X,A is a system Vof helices of four coils of wire.
  • B is a clasp of wood, but may be ofany suitable material'. Bcingitselftlxed, it supports the helix altogether at or near one end by clasping firmly the coils of coarse wire Y, which have their longitudinal hollow axis snugly iilled with the iron wires (L composing the electro-magnet; D, a hollow cap of sheetiron, driven on the end ot the wires.
  • D, Fig. X' is another form oi' the cud ofthe electroinagnet C, when the cap D, in' Fig.
  • N and O are metallic pieces, with sawcuts in top,which pieces pass through the side of the box, connect Vwith the Wires N' O' underneath.
  • P is a metallic part passing through the box, and connecting with the. wire W underneath.
  • R R' R R'" RW are also metallic posts or parts, passing through the box and connecting with wires underneath.
  • the wire N' connects with the first end 1 of the primary coil of wire in the helix.
  • the Wire O' connects with Rand K.
  • YV is awire, which connects P with G.
  • 1 is the first end of the iirst or inner coil of the helix, for the primary current, which wire is insulated, and after traversing with convolutions the length of the helix and back again, appears at 2, and is thence continued and joined with the metal 1t".
  • 3 is the first end of a coil of finer wire, joined with the wire 2, and after passing with its convolutions the length of the helix, and back again, appears at et, and is thence continued and joined with R".
  • 5 is the first end of a still smaller insulated wire, joined also with 1 and after passing with its convolntions twice backward and forward nearly the whole length ot' the helix, appears at (i, and is joined to PJ.
  • 7 is the first end of a still incr coil of insulated wire, which,
  • “.l is the knob on the end of a copper tube, T, which closes over the series of coils A, and is adjustable longitudinally to vary the power o1" the induced currents.
  • U is a wire, connecting VIt and O and K.
  • V is a wire, connecting M and Il.
  • the machine operates thus: The plug S, closing with l and It", the screw L, turned lo close l( with M, and the screw I touching the spring F; the screw J turned back so as not to touch this spring when it oseillates; the battery being connected with ils positive pole at N und its negative at O'.
  • Vhat i claim as new is 1.
  • An additional helix, introduced into the primary circuit ol" an electro magnetic machine, operating substantially as and for the purpose herein set forth.
