J OHANN MAXIMILIAN PLESSNER, OF S'IUTTGARI, GERMANY.
ANTIPHON E.
SPECIFICATION forming part of Letters Patent No. 322,003, dated July 14, 1885.
Application filed December 2, 1884.
To all whom it may concern:
Be it known that I, J OHANN IVIAXIMILIAN PLEssNER, a citizen of Germany, and a resident of Stuttgart, Germany, have invented a new and useful Improvement in Antiphones, of which the following is a specification.
The object of my invention is to produce an apparatus for excluding sounds from the car. This apparatus is simple in construction and easily and safely used. It is so constructed that it can be worn on a watch-chain as a trinket.
For the better understanding of my invention I refer to Figures 1 to l of the accompanying drawings, wherein Fig. 1 gives a view of the antiphone in realsize as worn on a watoh-chain. A A are two small grapnel-shaped stoppers, with thin shanks s 8, each having a ball, b b, at its lower and a half-disk, d d, at its upper end. The half-disks are each perforated with a hole for attaching the stoppers to a hook orring, B. Fig. 2 shows the position of a stopper when fixed to the ear, the ball entering freely into the outer earpassage, while the half disk, laying flat against the inner side of the scapha, is held in its place and slightly pressed in the direction of the ball by that part of the auricle called anthelix. Practical trials having established the fact that the depth and diameter of the outer ear passage vary considerably and independently of the size of the scapha, and the arranging of stoppers with adjustable shanks having proved inconvenient,I found it more practical to construct the antiphones of different but unchangable dimensions, as shown in Fig. 3.-
Each of the six balls shown below the line a; 1 and which I designate with the lettersAto F, may be fixed to one of the six handles shown above the line a; y. The handles I designate with the numbers 1 to 6. There are thus thirty six stoppers of varying dimensions,

as shown in Fig. 3. The width of the latter and of the shanks remain the same in all stoppers, and is as shown in Fig. 4, representing a section of an antiphone, 24:.
As regards the material of which the stopper may be made,I have found metal the most suitable, especially aluminum and nickel, silver, or gold, since it facilitates the application of light hollow balls, thereby forcing the Vibrations of the air to pass through various strata of metal and air before reaching the drum oft-he ear, which diminishes theintensity. All brittle substances,like glass and porcelain, are unsuitable, since a breaking of the thin shanks may cause an injury to the tympanum. Box-Wood, papier-mach, vulcanite, celluloid, and ivory may he used with advantage, but are less durable than metal.
Having now particularly described and ascert-aimed the nature of my said invention,and in What manner the same is to be performed, I declare that what I claim, is-
In an antiphone or apparatus for excluding sound from the ear, the stoppers A A, with shanks s 8, each having balls b b at the lower end and half-disk d d at the upper end, substantially as and for the purpose set forth.
In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 19th day of June, 1884.
