To all whom/it may concern:
Be it knownthat LEnwm W. RICE, J r.,-
acitizen of the United States, residing at Schenectady,- county of Schenectady, State of cation. 7 I 1 My invention relates to a device for protecting anvelectric circuit from the efiects of y a lightning orother higlrpotential discharge,
and comprises certain novel features, which l have pointed out with particularity in the appended claims. A
The invention itself, as exemplified in one of-the numerous embodiments of which it is capable, I have described in detail in the f llowing specification, which is to be taken in '1 connection with the accompanying drawings,
in which- I.
Figure 1 represents a plan-view of ainrcuitprotecting device or lightning-arrcster built in accordance with my invention, and Fig; 2
' a side elevation of the same.
"like. At each end of the rod is arranged a series of spark-gap terminals or balls, one of these series consisting of the balls 3, 4, 5, and 6, the last mentioned being provided with a binding-post 7 for connecting one end of the lightning-arrcster in circuit. The other end of the resistance-rod is similarly provided 'with a series of balls 8,9, '10, and 11,,the last mentioned being, like the ball 6 of the other series, provided with a binding-post 12, forming the remaining terminal of the lightning arrester. These ball s'orspgu'k-gap terminals may be formed-of brass or other suitable metal and may be arranged in two series, as
.shown, one on either side, so 'to speak, of the,
resistance-rod 2, or, if pleferred, one series onlymay be employed: Connection ground.
between the balls? and s and the adjacent ends of the resistance-rod 2, near which they'.
are located, by clips 13 14, electrically 0on nected withtherespective spark-gap terminals 'o balls-8 and 3.
A'series of rings 15, which may be split, 1 are sprung about .or shrunk upon' the resistance-rod2at intervalsin the length thereof:
so that 'eacliring'is separated from its nejgh form spark-gap terminals.
. In connecting up the lightning-arrester or.
protecting devicebne terminal is connectedto the line to protected and the other to minals 3 to 6, inclusive, and 8'to 11, inclusive,
In case a relatively smallj-dis-I charge passes through the ahrester the flow,
the circuit of the discharge being'cor'npleted tjrough the resistance-rod 2. The resistance of this rod issuch that it limits the value of the dynamo-current following a' lightning or other high-potential discharge to such a value that the arc-extinguishing action of .the se ries of spark-gap terminals mentioned is sufii':
cient to interrupt the flow .of current. In case a heavy discharge of excessive intensity takes place the path of thedischarge instead of following the resistance-rod 2 extends mostly along the series of rings 1,5 from rlng to ring. As soon, however, as the dynamocurrent starts in response to the path opened up by the high-potential discharge it flows not from ring to ring on the resistance-rod,"
,but passes instead through thedaetter path at -forded by the rod itself. The current thus deserting the'rings 15,' the arcs between the, rings are immediately extinguished, and the. current being reduced in value by the resistance 2 is interrupted through the ard-extiu;
guishing action of the lightning-arrester balls- 1 V in'circ'uit with the rod 2, as above described.
The lightning-arrester, as thus described,
therefore furnishes-a ready path for high-pof tential discharges and operates to interrupt the flow of current resulting from these dis- BEST AVAILABLE COP,
