' "Patented Feb. 12,1907:

cooperating with graduations l2 on the rack- Bcit known that I, AUsUs'rUs t). CAREY, a 4 bar to indicate the extent oi movement oi citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a certain new and useful improvement in Electric Regulators, of which the following is a lull, clear, and exact description.

The object of this invention is to provide a device by means of which the application and control of an electric current may be regulated in an inexpensive manner, the device being capable of use both as a regulator and as a receiver.

The invention comprises, i'unds ental tube of glass or other insulating ma conta ning loose particles or" con terial therein and arranged bets es ive plungers, one or both oi" 'c adjusted in order to collect the loose i into a more or less compact mass. iii both of these plungers may be wound insulated wire to form electromagnets ductoriums.

In the accompanying drawings, illu t ing the invention, in the several 'liguros of which like parts are similarly designated, Figure 1 is a plan view with part of an optionallyemployed shieldbroken away. Fig. 2 is a longitudinal section showing a variation in the arrangement of the phingers. Fig. 3 is a longitudinal section showing another variation in the arrangement of the plungers.

The base 1 may be of any -harm and mate rial, and in Fig. 1 it is shown of wood, haviiigbearingblocks 2, in which is supported a tube 3, of glass or other insulating or electric ally non-conductive material. in this tube is placed a quantity of loose particles t of electrically conductive material such as brass, steel, silver, or other alloy or metal confined between plungers 5 and 6 of equal or unequal length, one or both of them being capable of adjustment lengthwise of the tube in order to move the loose particles into a more or less compact mass, and thereby form a more or less e'tlicient conductor of electricin Fig. 1 the plunger 5 is supposed to be stationary and shorter than plunger 6, and the plunger 6 is shown adjustable by means of a toothed rack-bar 7, engaged by a pinion 8, operated by a key 9. The raclebar has its outer end supported in a bracket 10, and this bracket may be supplied with a pointer 11,

the plunger and the consequent degree of compacting thereby resulting upon the loose partic .s to prepare them for currents co ining in n greater or less distances or currents of more or loss strength. is shown in Fig. l, the plungers may be composed of rods of considerably smaller diameter than the bore oi the tube, and these rods may be supplied with one or more disks of substantially the diameter of the tul 0; but in anycase ti sends oi the piungcrs, which cooperate with the mass oi icles, must be of sulliciently close thr interior or the bore oi the tube to 10 particles past them. s may in wound with the same or uigths oi" insulated wire 13. shown in 5",; i, the wi e is alike upon both 'ilungers and may be a plied to form an elecrot or an indin oriinu, or, as shown in i one plunger may be an clectromagnet ie other an induetorium, or, as shown in one plunger maybe loft plain and the on her be an electromagnot or an iiuluctorium. Other variations in the arrangement of these plungers maybe used in carrying out the p urposes oi the invention.

The plunger rods and disks are construci ed ,o'l' soil. iron or other good conducting or insigneiic ma eiial, and either or both 0t S.ll(l rods may be wound between the disks with insulated wi: o i; o i'orzn oloc'ironnignei s or inductolines. in tilt preferred construction the leadin in iorn'inal oi' the windn-g is passed througn the outer disk oi the plunger and is carried outside oi tlro tube 3 in any suitable manner to be connected with one oi the tern inals oi the ('iiClllt in which the device is to be used, and the other term inzzl oi the winding is electrically connected with the inner disk oi the plunger.

It it be desired to form inductor iuns oi the plunger-rods, the rods are wound between the disks, as is usual in iiulucto'i'ium con- S'tIIlQLiUDS, both the torn inals of the secondary winding being electrically comic ct ed with the inner disk. it both plungeis are con s'truc'ted as electromagnets or iinluci'oiiuns, the windings are arran god revoisoly and the leading-in wircs of the windings are con nec'ted to the terniinels of the circuit in which the device is to be used, and the current passes through the windings of the electromagneis and from the magnets or plungers through the loose particles.
