CONNECTOR FOR ELECTROCHEMICAL APPARATUS..
SPECIFICATION forming part of Letters Patent No. 768,175, dated August 23, 1904.
i Application filed December 28, 1903. Serial No. 86.875. (No model.)
Bc it known that l, OLIVER 1).FRITCHLFL, a citizen ot' the United States, residing at Denver. in the county of Denver and State of Colorado, have invented certain new and useful improvements in Connectors for ElectrochemicalgApparatus, of which the following is a speciiication.
This connector is especially intended for use with storage batteries, electrolytic cells, and other apparatus requiring` an easily-detachable connector which will resist the action of corrosive liquids and fumes. Y
The connector comprises mercury cups, preferably of copper plated with nickehwhich are secured to the electrodes', a coupler, pref-- erably a heavy copper wire or rod sheathed with lead except at its ends, the ends of the sheath being grooved and formed into bulbs and the ends oi' the wire being nickel-plated, and soft-rubber sleeves which fit closely upon the mercury-cups and the bulbed ends of the coupler sheath and have punctured diaphragms to receive the ends of the couplerwire, but automatically close when the coupler is withdrawn, thereby preventing the cscape of mercury.
Referring to the accompanying' drawings,
Figure l is a vertical section through the connector and the upper ends of two electrodes joined thereby; and Fig. 2 is a vertical section through the -connector with its several elemerts detachech but in position to be assemble y The connector comprises a mercury-cup 1, preferably of copper plated with nickel orA some other metal which is insoluble in and non-absorbent of mercury. The cup is secured to the electrode 2 by an integral threaded stem 3. `When the connector is used for lead storage batteries, the stem is tinned and' cast into a lug e at the upper end of the electrode. The mercury-cup has external annular grooves 5 and is partly filled with inc rff cury 6. Y
The coupler 7 consists of a heavy copper wire or rod 8 covered with a lead sheath 9 except at the ends l0, which are received by the mercury-cups. The lead sheath may be cast on the copper wire, this being previously tinned. The exposed ends 10 which enter the mercury are plated with nickel. rllhe lead sheath has grooves 11 near its ends and the ends are formed into bulbs 12. The exposed ends 10 oi' thecoupler-wire should be ot' considerably less diameter than that oi' the recesses in the mercury-cups and should not cxtend to the bottom of these cups. This not only prevents the coupler from displacing' the mercury from the cups. but allows either electrode to vibrate without transmitting the vibrations to the other electrode, the coupler being supported entirely by the rubber sleeves. The connector is thus especially' serviceable for use. with autoniol )llc-batteries.
Each oi' the soft-rubber sleeves 13 has a lower central bore le, which lits closely upon the mercury-cup and usually prevents any electrolyte from creeping up the cup. As a further precaution, an acid-prooi' grease may be placed in the cup-grooves 5 and around the electrode-lugs 4. Each sleeve also has an upper central bore 15, which receives and tits closely upon the lead bulb 12 ot' the coupler '7, preventing any accidental dislodgrnent of the coupler. Between the bores 14: and 15 is an intcgraldiaphragm 16, which is centrally punctured to receive the end 10 ot the coupler-wire when forcibly inserted. but to automatically close when the coupler is with drawn` thereby preventing` any escape ot mercury from the cup.
This coupler has been found to be entirely prooi' against the action of the acids and fumes of the ordinary lead storage battery, remains in perfect condition without attention, pernzits the elements to be easily uncoupled, and avoids the broken connections lwhich occur when the elements are rigidly connected by lead strapsjlused together.
L/n electric connector, comprising a merters said cup, and a carrier of flexible, nonconductive material supporting said coupler with its end within but out oi' contact with said cup, as set forth.
52. An electric connector, comprising a mercury-cup, a coupler having an end which ente; said cup, and a sleeve of flexible, nonconc mfyr-cup, a eoupler having an end which enductive material carried by said cup and supporting said coupler with its end within but out ol' contact with the cup, as set forth.
