Description

R. CONNELL. COMBINATION TERMINAL BLOCK AND LIGHTNING ABRESTER.
7 APPLICATION FILED JUNE 20, I9I9- 1,328,720, Patented Jan. 20, 1920.
To all whom-it may concern:
'noY coNNnLL, or BUFFALO,
new Yjonx.
COMBINATION TERMINAL BLOCK AND LIGHTNING-ARRESTER.
Application filed June Be it known that I, ROY CoNNnLL, zen of the United States, and resident of Buffalo, in the'county of Erie and State of New York, have invented a certain new and useful Combination Terminal Block and Lightning-Arrester of which the 01- I lowing is a specification.
This invention relates to a combination terminal block and lightning arrester.
' The object of the invention resides in so constructing the device that it will operate as. an ordinary but will permit tential discharges the grounding of high poto protect the circuit in I which it is interpolated.
' relation to each I accomplish this object broadly by interposing a resistance element of carborundum or the like between the two binding posts of the "terminal block, using one of the binding osts for the connection to the line and to the relay and grounding the other bindin post. o v
Furt ermore, the carborundum resist ance element is interposed between the binding posts in such manner that it may be readily applied and so that it will notinterfere with the.normal function of the binding posts.
In the drawing:
Figure 1 is aside elevation of a device constructed in accordance with my inven- -p to, so that the circuit from the tion;
lFig. 2 is a and a Fig. 3 is a fragmental detail.
The form of the invention illustrated in the drawing includes a base 1 of suitable insulating material, such as porcelain or the like, on which are mounted twolbinding posts 2 and 3, which are arranged in spaced other and extend above the upper face of the base. A pair of collars e encircle the binding posts 2 and 3 and rest upon the bosses 5 of the base. Between these collars is interposed the resistance element 6 which is made, preferably, of carborundum. The ends of this resistance element are provided with seats 7 to closely fit against the outer faces of the collars. Lock nuts 8 are mounted on the binding posts above the collars 4.. Between the upper edges of the collars and the lock nuts 8,

brass washers 9 are interposed, and these washers are of greater diameter than the Thus, when the nuts 8 are in their locking positions and the; carborundum block or resistance element is in place, the
displacement of the element. will be prevented. Binding nuts 10 are also mounted on the binding posts 2 and 3 and interposed between the lower ends of these nuts and the upper faces of the nuts 8, are a tional brass washers 11, between which the ddiwires from the line, to the relay and to the. ground are engaged and securely clamped in the usual'manner.
In Fig. 2 of the three of the devices which are arranged in parallel, the grounded terminals 2,bein.1g t

will be readily" realized that the device may be used singly or may similar devices if desired.
When a normal voltage is used the curthe line and relay drawing I have shown be connected tootherwires and .through the binding post to which they are attached,

However, when the voltage is increased to an abnormal extent, the current will flow through the and will be grounded through the binding 0st 2 and the ground wire connected thereline to therelay will be 'protected- Thus it '-.will be seen that I have constructed a combination terminal block, and lightning arrester in which the resistance the high potential discharges alone, IS inelement, which} permits but the circuit will not be grounded because of the high thereon,
