CHARLES a SHEDRICK, 0F SHERBROOKE, QUEBEC, CANADAj ELECTRIG CONTROLLER' man sq. is, 100e.

Anima. m mgm minos. um L mans.

To all whom it may concern:

Be it known that I, Cnaanns E. SnEDaIcx, a subject of the King of land, residing at Sherbrooke, county of Sher rooke, Province of Quebec, Dominion of Canada, have invented certain new and useful Im rovementsin Electric Controllers; and I do ereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled'in the art to which it appertains to make and use the same.

M 'invention relates to electric controllers.

T e object of my inventionfis to provide an a paratus articularly for'electric lights whic is simp e in construction and automatic in its action.

A further object of my invention is to provide'adjustable means -for ap l the invention to a varying number of) e ectric lights or for similar purposes; and my invention consists of the construction, combination, and arrangement of parts, Yas herein illustrated, described, and claimed.

In the accom anying drawings, fo part of this app ication, I have illustra one form of embodiment of my invention, in

which drawings similar reference characters designate correspon parts, andinwhich- Figure 1 is a side e evation. Fig. 2 is a plan. Fig. 3 is a central vertical section taken longitudinally approximately on line 3 3 of Fig. 2, and Fig. 4 is a`transverse vertical section taken approximately on line 4 4 of 2. d d b e erring to rawings,5 esignates a ase, in one corner of which is disposed a bindingpost 6, which receives a feed-wire 7. Disposed adjacent the o posite sides of the base are plates 8, on whic are disposed standards 9 in electrical connection with kthe plates. The feed-wire 7 is carried from the bindingpost 6 and placed in electrical connection with the plate 8 on one side of the base. The

r ends of the standards 9 are provided wit bearings 10, xadapted to receive the rockable shaft 11. Disposed on rockable shaft intermediate of the beari are a plurality of receptacles orcu 12, t e periphery of each of which is provil ed with an o which may be conveniently closed, as y the screws 12.` Each of the receptacles 12 is in electrical-connection with its adjacent rockshaft 11, and said receptacles are electrically se V'n.rated, as b the disk 13, com sed of suitable insulat1on,.which also ins ates adjacent ends of the rock-shaft.

`14 and For the purpose of making electrical connection between receptacles 12 the disk 13 is provided with an opening 14, and each of said receptacles has'therem a body of fluid conduct mattei; 15, preferably mercury. It should Fig'. 3 that a connection vll be made beL 'tween said receptacles when they are rocked in such position that the mercury can flowthrough opening 14 and that they will be apparent upon an inspection of electrically separated when they are rocked to such a 'tion that the o 14 is above the .leml of the mercur facilietween said cups and to prevent disarrangement of the working of the apparatus by the mercury beL coming clogged 1n said openin I provide a member- 16, disposed through tide disk 13 and preferably composed of platinum and of an inverted-U sha with its ends disposed with relation to the evel of the mercury, so that in one position it will not contact therewith and that when in another osition it will contact with the mercury, andp thereby brid e the insulated space and form an electrica connection betweensaid receptacles.

Carried one side of the receptacles is a b screw-threaded rod 17, adapted to receive the nut 18 and a check-nut 19. Disposed on one end of the base 5 is a standard 20, provided at its upper end with an offset 21, on which is disposed a'bod of insulation 22, in the path of movement o the rod 17 when the receptacles 12 are rocked.

Projectin from and carried by one side of the receptac es 12 is a rod 23, to which is connected a link 24, ca preferabl a plate o metal working into a series co A26, and leading from the coil is a wire 27, carried to the binding-po base 5, from whence it is carried on tothe lights orplace of consumption.

In the operation of my invention the nut 18 and the check-nut'19 are set' at such distance on the screw-threaded rod 17 that the electrical current necessary to run a given number of lights will not energize the coil 26 suiciently to attract the core 25, and thereby rock the receptacles '12 sufficiently to break the connectiontherebetween. Should g a core 25, which is 9s Y st 28 on the more -lights be added to the circuit or more current turned on, the coil 26 will be energized sufcietly to attrxct the core 25 therey rockin' g t e receptac es until the opening t e conductin members 16 are thrown to the position own in' dotted lines in Fig. 3, whereby the connection will be broken and remain broken until such excess of current is removed. When the excess is removed, the weight of the nut and the check-nut will overcome the attraction ofthe coil, and the arts will resume the position` shown in full ines;

Havin thus fully described my invention,

what I c aim as new, and desire to secure by 1. -In a device of the character described, a plurality of rockable receptacles, means for rocking the receptacles, means for electrically separating the receptacles, means for au-` to currents of varying intensity, comprising a rod carried by the rece tacles `and screwthreaded Weights dispose thereon.

3. -In a device 'of the character described, a

I, 4 k base, conducting-plates on the base, a feed- 3o` Wire connected to one of the plates, standards on the plates, a plurahty of electricallyseparated receptacles supported by the standards in electrical connection with the plates,

means for making a connection 'between the receptacles when they are rocked and thereby makin a connection between the lates, a coil on tie base, means actuated b t e coil for urocking the receptacles, means or limt- Iing the movement of the receptacles, anda 4o wire leading from one of the lates into the coil and leading from ythe coil? 4. In a device of the character described, a pair of electricall -separated plates, standards carried by t e plates, a shaft on the standards, .means `for electrically separating the ends of the shaft, receptacles carried by the shaft on the opposite sides of the separating means and in electrical connection with the shaft, means for bridging the separating. means, 'and means for rocking the shaft to render the brid ing means operative.

In witness whereof I ave hereunto set my hand in the presence of two witnesses. CHARLES E. SHEDRICK.
