1,0Q6As65. Specification or I? Application filed Tiny 7.911.
To all whom it may concern Be it known that I, ADRIAN H. Herr, a citizen'of the United States, and resident of Penacook, county of Merrimack, and State 5 of New Hampshire, have invented an Ln proved Electric Shunt Connection, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawings repre- This invention has for its object the pro duction of a novel electric shunt connection adaptable for use in connection with a galvanometer, ammetencr any other instrument placed in parallel circuit therewith, by means of which current or voltage is to be measured.
. One of the particular objects of this invention is the production of a form of connection between the shunt, the measuring instrument placed in parallel circuit therewith, and the source of current, arranged so that proper proportionate part of the current must necessarily pass through the shunt whenever the galva'nome'ter or animeter is placed in parallel circuit there with.
Another of the special objects of this invention is the production of a method of securing contact between the shunt and the source of current, whereby a perfect connection must. be established between the same, before the measuring instrument placed in parallel circuit therewith can receive any current.
Another particular object in View to provide such a connect-ion between the shunt, the measuring instrument placed in parallel therewith, and the source of current, so that 49 if the shunt becomes disconnected accidentally or otherwise from the circuit, the Incas uring instrument will also become discern ncctcd, and will not be injured by V passage of a greater amount of current through the same than is proper.
With these andbther objects in View the invention consists of certain novel features of construction and combinations 0* parts which will be hereinafter more fully (le- 50 scribed and pointed out in the claims.
In the accompanying drawings is shown the preferred form of the invention.
In said drawings, Figure l is a plan View of the shunt and connection as used on a switchboard, one end of the shunt being through wire 7 to the instrument.
Having described my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination of an electric shunt with a particular form of connection consisting of a flat late, a threaded bolt projecting upward t rough a hole in said plate, said hole\being larger than the bolt, means for attaching said plate to a switch board, means for ringing said plate, bolt, and shunt in electrical contact, and means for attaching a terminal wire toathe lower end of said bolt, as described and set forth.
2. The combination of an electric shunt with a flat rectangular plate, a threaded bolt, said plate being pierced with a hole larger than the diameter of said bolt, a milled and threaded nut on said bolt, and a nut for attaching a terminal wire to the lower end of said bolt, as described.
In testimony whereof, I have signed my name to this specification, in the presence of two witnesses.
