To @ZZ 'whom t mag/concern:

Be it known that I, CHAnLns T. CLAYPooLn, a citizen of they United States, residing at Sioux City, in the county of Woodbury and State of Iowa, have invented new and useful Improveing is a speciiication. p

In electric meters as ordinarily constructed anism is operated and controlled is connected with one of the line-wires outside the metercasing and extends through an opening in said casing. This shunt has no effect whatever upon the iiow of current through the meter to supply the translating devices; but if of the meter will cease to operate. It has been found by actual experience that dishonest consumers of current can and do disconnect or break the shunt-circuit in question by simply removing the circuit-wire from its socket in the meter-casing or by cutting it, and thereby prevent the registration by the loss-to the electric companies in thel dierent large/cities from this cause is estimated at many thousands of dollars. To prevent detection, the consumer connects up the shunt prior to the visit of the inspector or meterreader. By my invention kI provide means whereby this stealing of current by the cutting out of the shunt which controls the registering mechanism is absolutely prevented.

of the shunt-circuit wholly within the metercasing and secure in an opening in said caspasses a T coupling-piece of brass, copper,`

arm of which the shunt-wire is attached and sections'of the outer line-wire are attached.

The details of my invention will hereinafterappeanand the novel features thereof will be set forth in the claims.A Y y, f

In the drawing forming part of 'this specication, the figure thereof is a diagrammatic view illustrative of my invention.

The casing lof the `meter may be of any suitable form of construction, but is provided the shunt-circuit wire controlling the metercoupling-piece is solid and of sufficient thickness to preventy cutting. One arm thereof extends down into the meter-casing l through the opening 2 and is firmly screwed or otherwise secured in place. Its lower end has connected with it the wire 8, forming part of the shunt-circuit through the meter, and the other arms of said coupling-piece have attached to them the ends of two sections of the line-wire 5. By this construction it will be seen that the wire portion of the shunt-circuit through Which the registering mechanism is operated and controlled is wholly inclosed within the meter-casing -l and is therefore out of reach of a dishonest consumer who would want to tamper'with the same for the purpose of preventing the proper registration of the'current consumed by him. Furthermore, the T coupling-piece 7, which is firmly secured to the meter-casing, cannot be disconnected therefrom without opening the meterand removing the dial or registering mechanism. v
