IMPROVEMENT IN ELECTRO-MAGNETIC APPARATUS FOR MEDICAL USE.

The Schedule referred to in these Letters Patent and making part ofthe same To all Iu'hom It muy concern:

Be it known that I, CHARLES Rnrrz, of Indianapolis, in the county ot' Marion and State ot' Indiana, have invented new and useful Improvements in Electro-Magnetic Apparatus; and l do hereby declare that the following is a full, clear, and exact description thereof, that will enable skilled artisans to make and use .the same, reference being had to the accompanying drawings 'and to thc letters ot' reference marked thereon making part ot' this spcciiication.

This invention relates to construction and arrangement of the battcry,.and its permanent connections with the coil 0f electro-magnetic apparatus, with a view to render it suiliciently portable to he carried in the pocket, and to be used by persons inexperienced in and ignorant of its'ol'ieration.

Iligure l is atop or plan view of thc apparatus, showing the arrangclncnt ofthe battery and coil in a suitable case, in which space is also provided in which to store the cords and handles connecting with the poles,

and a phial for containing sulphate of mercury, or other v analogous dry acid, for exciting the battery.

Figure 2 is a plan view' of the apparat-ns, showing, in red lilies, the arrangement of the wires beneath the bottom, forming permanent connections ot' the battery with the coil.

Figure 3 is a top or plan view ot' the battery.

Figure 4 isa vertical transverse section oi' thc same.

A is the iron cup or trough, and

I5, the zinc cup of the battery. l

The iron cup A is furnished with a projection, (l,

which tits into ai correspoluling recess, a', in the case,

to prevent it by accident being set into the place ot" the zinc cup, the projection a preventing it ii'onrgoiug down low enough to restl upon the studs I 'l L in thc compartment ol'thc zinc cup, il', by accident, itshould bc placed in that compartment. It will bc readily understood, of course, that various devices' may he cinploycd to effect the same purpose.

lhe movable partsoi'the battery, I) being the iron, and C the zinc, are also so arranged that their transposition would bc readily detected, as, unless.thc hole y inthe cross-picec G is in proper position to receive the pin II. in the partition separating the two cups, the movable parts of thc battery will not go down into place.

- In order to make the apparatus within the smallest practicable space, and the battery to evolve the rcquired strength ot' electrical current, .l divide the cups by partitions I) and F, as shown, the partitions in each cup being of the saine metal asthc cup in which they are placed; and also ina-ke the movable parts ot' the battery with leaves, C D, corresponding to the spaces formed by the partitions, thus exposing a very extended surface of metal to the action of the acid,

the strength of the electrical current being in proportion to the surface of metal exposed to the action of the acid.

The red lines in fig. 2,sl1ow the arrangement of the wires connecting the battery A B with the' coil I. 'Ihcse connections are so constructed and arranged as to be permanent, and are at all times in readiness to conduct the electricity evolved by the battery to the coil whenever the acid is placed in the cups andthe movable parts of the battery are putin place.

The electricity is conveyed from the battery to the coil as follows, to wit: From the iron cup A to the points SS; thence along thc wire J tothe post K, connected with the v ibrating armature L; thence along the vibrating armature to the post -O,'eonnect ing with the set-screw l); and'from thence along the wire Q both to the pole marked I l), (indirect posi- 'tive,) and to the pole marked I) I, (direct positive,) also to the end Itot' thc large wire ot' the coil I.- From the zinc cup B it is taken up by the studs or points 'I I T, i'roln whence it is conveyed along the wire U to the pole marked I) N, (direct ncgative,) and also along the wire 'V to the end IV ot` the large wire of the coil I. One end ot' the liuc wire that is wrapped on the outside, and forms part of thc coil I, is soldered /to thc cud IV ol' the large wire, and leads thence by X. to the pole I N (indirect negative,) and the other end to the end w ot' the large wire., y

It will bc readily understood by those skilled u1 electro-magnetic apparatus that the movements of thc electrical currents in this apparatus do not differ materially from that of others, and that the poles may he readily changed by making different connections of the wires leading from the battery to thc coil I; hence noclaim is made to anything 1norc,in this respect,

than to thc arralllgcment of the connections in this particular device as a matter ofconvenient and economical construction, the claim being more especially confined to the construction and arrangement ot' the permancnt connection ot' the battery through the points h S S and 'I l T, either under the lcups A B ory at their sides, as may be found most convenient, and being at all times in readiness to convey the electrical current from the battery to the coil, without requiring skill or knowledge on the part of the operator to make the connections, as in othc apparatus.

'Ihc use of ,acid inA connection with the battery and othc of thc apparatus, constructed as herein described so a matter of' great convenience as well as eleanlin'esslf- When required to be put in operation, the movable parts C I) of the battery are to be taken out, and about four of the small copper spoons accompanying.- the apparatus full ot' the dry acid, contained in't'hc phal Y, is put into each cup A B, and is then made iud by the addition of aismalt quantity, say about two large tea-spoonfuls, of water. 'lhe movable parts C D are then put in place, when' the evolution ot'the electrical current commencs, the quantity of which is in ratio to the depth ot' the acid contained in the cups A B.

For a strong current, the handles N N' are connected with the poles marked l l and l N, (indirect positive and indirect negative, respectively) and fora weaker current, with the poles marked l) l and D X, (direct positive and direct negative, respectively.) Ati any time during the action ot' the battery a violent shock maybe produced by depressing either end C or D of the movable part of the battery deeper into the aeid. The vibrations of the armature l), alternately breaking the current and connecting it with great rapidity, induces a smooth current, which is very de* sirable, in heilig less disagreeable to the patient when applied to the treatment of disease.

M is a regulating-bar, made iu the usual, manner, and inserted in the-interior ofthe coil l,-\\hieh is also made in the usual manner, except that the inner coil, of large wire, is wound upon a hollow shaft or spool of wood, of which care the heads, all turned in one piece. The shaft is lined on the inside with sheet'- iron, and in the end next to the armature a cylinder of soft iron is permanently lixed. Ihe cylinder of sott iron is shown in dotted lilies at g, in lig. 2.

lhe partitions lil and F ofthe cups .k and B do not extend entirely to the bottom of the cups, but space is lel't for the acid to flow freely beneath them, as shown in iig. 4. l

The battery is easily cleaned by taking out the movable parts C D, and taking out and emptying the cups A B, which then require no washing or other cleansing. (Jare should be taken, however, to keep the bottoms ot' the cups clean, especially where they come in contact with the studs S and T.

lhe advantages ot' this apparatus over those of ordinary construction consist* First, in -its coinpactness and portability.

Second, in avoiding the use of fluid acids and their attendant dangers 'and disagreeable odor.

Third, the completeness ot' the apparatus within itself, requiring nothing outside of it to set it in operation but a small quantity of water.

Fourth, the strength ot current, for all required purposes, produced by a small and compact apparatus.

Fifth, evenness of current, effected by the more rapid movements of the vibrating armature.

Sixth, simplicity of construction, operation, and use,

on account ofthe arrangement and permanent connections oi' the battery and the coil.

Seventh, avoiding the possibility of changing the poles by unskilled persons.

Eighth, susceptibility to produce violent shocks by simply immcrsing either of`-the movable parts G or l) deeper into the acid.

Having thus fully described my invention,

That I claim as new, and desire to secure by Letters latent, is

1. The arrangement of the cross-piece G and pin H` in a galvanic-battery, in the manner and for the purpose substantially as specified.

2. The arrangement herein shown and described of the iron cup A, zinc cup B, removable leaves O and D, constructed respectively of iron and zine, as described, together with the iron and zinc partitions E and F, when the several parts are constructed snbstautially as and for the purpose specified.

CHARLES REITY.
