ELECTRIC EYE-SHADE.

SPECIFICATION forming part of Letters Patent No. 298,397, dated May 13, .1884.

Application filed November 5, 1883. (No model.)

2'0 wZZ whom it may concern:

Beitknown that I, LOUIS K. OPPENHEIMER, a citizen of the United States, residing at 195 NVest Fifth street, Cincinnati, Ohio, have invented new and useful Improvements in Electric Eye-Shades, of which the following is a specification.

My invention relates to eye-shades, its object being to combine therewith suitable ap-. paratus for generating and maintaining a current of electricity to be administered to the wearer by and during the ordinary use of the eyeshade, for the purpose of stimulating and strengthening the functions of the nerves and organs of visions.

To this end my invention consists in combining and arranging upon the shade one or more simple galvanic piles with suitable insulated connections and electrodes arranged to rest against or in the region of the temples. To these may be added an inductive coil and automatic circuit-breakers, in which case the primary of the coil is connected with the piles in a closed circuit, while the electrodes form the termini of a broken circuit, including the secondary of the induction-c0il.

Apparatus embodying both forms of my invention is illustrated in the accompanying drawings, in which- Figure l is a perspective View of a shade provided with a single-circuit apparatus, and Fig. 2 a similar perspective view of a shade provided with induction-coil and circuit in addition.

Referring to the drawings, A designates an eye-shade of ordinary form and construction, having attached thereto near each end a single galvanic pile, B, consisting of two or more elements or plates, 1) b, of copper and zinc. The ultimate zinc element or plate of one pile is connected by an insulated wire, a, or band of metal with the ultimate copper element of the opposite pile, the wire or band C passing around the front of the shade. In general, but one element of copper and one of zinc are used in each pile, one of these (the opposite in each pile) being secured to but insulated from the shade A, while its complementary plate is mounted on a spring supporting-arm,

lVhen in use, it is also preferable to interpose a pad of similar material between the skin and the electrodes. Thus arranged,ias shown in Fig. 1, the head of the wearer closes the circuit and receives and transmits the direct current from one electrode to the other. In Fig. 2 the circuit between the piles is closed by the conductingwires a (6, connecting opposite poles of the pile-batteries B, in one of which is arranged the primary of an ordinary induction-coil, D, provided with a spring-armature, (Z, and contact-points, constituting an automatic circuit-breaker of ordinary simple construction. The secondary coil is connected at opposite ends by insulated wires 0 6 with the electrodes 0, whichgin this case are insulated from the piles, its circuit being completed through the head of the wearer as before.

The construction in detail is fully indicated in the drawings, and will be readily under stood by those familiar with the art.

It will be obvious that one of the piles may be dispensed with, and the circuit arranged for one only; but I prefer the arrangement shown.

Having described my invention, I claim and desire to secure by Letters Patent 1. In an electric eye-shade, two sets of copper and zinc plates, constituting the elements of galvanic piles, arranged one at each side of the shade, in each of which one ultimate element or plate is attached to the'plate, but insulated therefrom, and the other mounted upon a spring-arm electrically connected with an electrode or distributing-plate arranged to act against or in region of the temple of the wearer of the shade when in use, said plates forming a clamp to hold removably a moistened pad,

In testimony whereof Ihave hereunto set my hand in the presence of two subscribing witnesses.

LOUIS K. OPPENHEI MER.
