UNITED STATES DAVID H. IVILSON, OF NORMAL, ASSIGNOR TO THE PATENT OFFICE.

AMERICAN ELECTRIC FENCE COMPANY, OF CHICAGO, ILLINOIS.

SPECIFICATION forming part of Letters Patent No. 455,696, dated July 7, 1891.

Application filed August 25, 1890. Serial No. 362,996. (No model.)

To all whom, it may concern.-

3e it known that 1, DAVID H. WILsoN, a citizen of the United States, residing at Normal, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in Switch-Boards forElectrio-Fence Stations, of which the following is a specification. 1

My invention relates to switch boards adapted to be used at a station wherein is lo- 'cated the electric generator and other apparatus necessary for the proper equipment of an electric fence, as it is termed, an electric fence of the kind referred to being a fence composed of one or more strands of uncovered wire not in electrical connection with the ground, each of such strands, where more than one is used, forming an electrical conductor over which an electric current will be automaticallyconveyed when any animal or other electric conductor comes in contact therewith and with the ground, thereby grounding such wires. In a fence of this character one end of each of the strands of wlre forming the fence is-when the fence 1s in condition to automatically impart a shock to an animal touching and thereby grounding any one or all of such strandsconnected with one of the wires extending from an induction-coil or from a magnetoelectric generator, and the other end of each of such strands of wire is disconnected from such induction-coil or from such magneto-electric generator and not grounded, but adapted to be connected to such induction-coil or magneto-electric generator by a return-wire or by grounding, as preferred, Whenever desired; and in.a fence of this character the other wire extending from the induction-coilor from the magneto-electric generator is grounded, such ground wire being arranged to be cut out from the circuit when a return-wire is employed for completing the circuit.

The object of my invention is to provide means for readily connecting and disconnecting one end of all or any of the strands of wire forming the electric fence with the wire extending to the induction coil or coils when an induction-coil is used for generating the desired current, or to the magnetoelectric generator when one is usedinstead of an induction-coil for generating the desired current; to provide means for connecting with or disconnecting from the induction-coil or from a magneto-electric generator that end of the strands of wire which is ordinarily in an electrical connection with such induction-coil or magneto-electric generator; to provide means for readily forming a closed electric circuit consisting of any one of the strands of wire forming the fence, within which circuit shall be contained a magneto-electric alarm-bell, constituting the signal by which a test may at any time be made of the electrical conditions of the strand tested, and to provide means for readily disconnecting any one of the strands forming the fence from electrical connection with the" induction-coil or magneto-electric generator and to connect or disconnect at will a-primary battery with the strand so cut out of the circuit connected with the induction-coil or magneto-electric generator, such primary battery having or adapted to have placed in the circuit thereof a telegraph-instrument or telephone. v

I .have illustrated my invention by the drawings accompanying and forming a part of this specification, in which Figure 1 is a front elevation of my invention with wires attached thereto extending to an induction-coil actuated by'a primary batteryalsoinanelectricalconnection with theinduction-coil t0 the fence, toatelegraph-instrument, and to a telephone; and Fig. 2 is a rear elevation of my invention, showing the manner in which the several binding-posts thereon which are in permanent electrical connection are wired together. Fig. 3 is adiagram- Ina-tic view showing the entire system consisting of the fence and my invention applied thereto.

Like letters and figures refer to like parts throughout the several views.

X is the primary battery. A magneto-electric generator may be employed instead and in place of the primary battery, and if a magneto electric generator is employed wires would extend therefrom directly to bindingposts E and O, hereinafter described, on the switch-board.

Y is an induction-coil,and y y are wiresextending from primary battery X to induction-coil Y.

y g are wires extending from the induction-coil to binding-posts E O on the switchboard.

Z is a telegraph-instrument, and Z isa telephone. I

' Z is a wire extending from the telegraphinstrument to binding-post S on the switchboard, and Z is a wire extending from the telephone to binding-post T upon the switcln board. Z* is a primary battery connected by a wire Z to the telegraph-instrument and to the telephone and by wire Z to the groundplate Z y A is the base-board of myimproved switch.

13 B are magneto-electric alarm-bells, and b is the hammer thereof.

.C O are binding-posts electrically connected in the ordinary manner with the electromagnet-actuatin g hammer b of the alarmbells B B. i

D is a wire electrically connected at one end with binding-post O, and, after passing through a hole in base-board A to the rear thereof, connected at the other end with binding-post E, hereinbefore referred to'as electrically connected with wire y. To the binding-post 0 there is electrically connected one end of wire D, the other end of which wire, after passingin like manner as wire D through a hole in base-board vA to the rear thereof, is electrically connected with post F.

F is a metal spring-arm pivoially secured on post F.

f is a handle on pivotal arm F, by which such arm may be turned. .1

F 1 F are metal spring-arms, each pivotally secured by pivot f f f to arm F, and each having a handle thereon, lettered, respectively, f.

G G G G are posts, upon the upper face of which pivotal arms F, F F and F may be respectively placed in contact and in electrical communication with, and it will be ob served that pivotal arm F may be brought .in contact with each of the posts G, G G

andG.

G is a pin forming a stop tending to hold pivotal arm F on post G, thereby preventing it from leaving its position on the post G when any one or all of the pivotal arms F F and F are turned off from contact with posts G G and G H, 11 ,11 and H are wires upon the back face of the base-board A, electrically connecting posts G, G G and G respectively, with binding-posts I 1 I I.

1, 2, 3, and 4 are wires electrically connected with binding-posts I, I 1 and 1 respectively,

and forming the first, second, third, and fourth strands of an electric fence, wire 1 being the bottom strand and 4 the top one thereof.

J, J J and J are binding-posts upon the switch-board, to which the other and return ing end of fence-wires 1 2 3 4c are respectively secured.

K, K K and K are wires secured at one end, respectively, to binding-posts J, J J and J and at the other end to posts L, L L and L. i

M is a post having pivoted thereon springarm N, such spring-arm being adapted to bring into electrical connection with post M any one of the several posts L, L L and L when the armN is swung over such post. Post M is electrically connected with post 0 by wire m.

P is a post arranged at one end of the series of posts L, L L and L and, like them, being adapted to be electrically connected with post M by having the arm N placed thereover.

p is a wire secured at one end to post P and at the other endv to post Q.

g is a wire extending from post Q to the ground.

R is a pivotal switch-arm connected by Wire with post 1 Arm R is adapted to be turned to the right or to the left andlinto electrical connection with posts'S or T, as desired. To these posts S and T are secured, as hercinbefore described, wires Z and Z respectively.

In order that the operation of myinvention may be fully understood, I will describe this operation in use with an induction-coil for generating the necessary electric current; but it will be observed that in place of such induction-coil a magneto-electric generator may i be employed, if preferred.

The primary current generated by the battery X extends on wires y 2 through the induction-coil Y. The secondary and alter-nab ing current will thereupon extend from such induction-coil on wire y to post E, through such post, and from thence on wire D to post 0, thence through the coil-actuating hammer b of alarm-bells B B to post 0, from thence on wire D to'post F, from thence on pivotal arms F F F F to posts G G G G*, from thence over wires H H H H to posts I, 1.

1 and I, and from thence on wires 1, 2, 3,

and 4:, forming the fence, and, extending over such wires, or that one thereof, if'any, which is grounded, to the point of grounding, will return by the ground to ground-wire q, thence over wire (1 to post Q, thence over wire 19 to post P, thence over pivotal arm N to post M, thence over wire m to post 0, and from thence over wire 1 to the induction-coil Y, thereby completing the circuit.

If no one of the strands of wire forming the fence is grounded, each of such wires, when the fencesurrounds the field or other inclosure, being returned to the switch-board and secured to posts J J? J J respectively, pivotal arm N be turned on pivot M, so that the free end-thereof is over and in electricalcontact with any one of the posts L L L L such posts being respectivelyconnected by wires K K K K", as her inbefore described, with posts J, J J 3, and J a closed electrical circuit will be formed over some one of the strands of wire forming the fence. For instance, if arm l be in contact with post L,

as indicated by the dotted lines in Fig. 1 of .the drawings, a closed electric circuit will be formed thereby, and an electric-current will extend entirely around the inclosure upon wire 4 or the top strand of the fence to post J thence over wire K to post L thence over lever N, post M, Wire m, post 0, and wire g to the induction-coil Y, as hereinbefore described. By turning lever N upon post L the same circuit will be formed, with the exception that wire 3 of the fence will be substituted as an element therein for wire 4, which will thereby be dropped from the circuit. Wires 1 or 2 may in like manner be placed in aclosed circuit by placing arm N the drawings, Fig. 1, if any one of the wires 1 2 3 4, forming the fence, is grounded the alarm-bells B B will be rung, as above described, and in order to test, if any, which one, or, if more than one, which ones, of such wires are grounded pivotal levers F 1 F are turned away from contact with posts G Giand G ,and,lever F being in contact with post-head G, if the alarm-bells B B continue to ring, wire 1 of the fence being the only one in electrical communication with post C through arm F',in contact with post G, such wire 1 of the fence is grounded. By turning lever F upon post G2 the'bell will continue to ring if wire 2 of the fence is grounded, such bell ceasing to ring if wire 1 is not grounded. Wires 3 and 4 may be tested in the same man ner by turning the lever F upon posts G and Gflrespectively. By turning lever 13 away from contact with post G wire at of the fence is thrown entirely out of the circuit traversed by the current, if any, from induction-coil Y, and thereafter by turning switchR to post S and grounding wire 4 by a suitable conductor'at any point selected as a receiving-point the telegraph-instrument Z may be'operated and messages sent and received on wire 4 from the station to the receiving-point, provided, of course, that a receiving-instrument be placed in the circuit in the ordinary manner.

such arm be turned to post If, instead of turning the arm R upon post S, T and wire 4 be grounded at a point desired for a receivingstation, with a telephonic receiver placed in the circuit, telephone Z' may be worked over wire 4.

It will be observe'd that any person may ground, say, wire 4 at any point on the fence, and if such grounding be done by a regular series of movements there will therebybe rc- Again,

ceived a signal upon bells B B, and upon receiving such signals the operator at the station may throw any agreed wire out of circuit with the induction-coil in the manner last described and throwinto circuit on such wire either the telegraph-instrument or the telephone, as called'for, and messages may thereby be sent and received in the ordinary manner.

Having thus described my invention, What I claim, and desire to secure by Letters Patent of the United States, ish 1.
