T'.aZZ whom (it may concern:

Be iliknown that I, ALoonx Ramon, of

the city county, and State of New York, have invented a new and useful Improvement in Telephone Adjuncts, of which the following is a full, clear, and exact descripnun. 1 i

p My invention relates to-improvements in that class of tele'p'luznejapparatus whiclr'are used in connection with a telephoneto assist hear ng, but wh ch are not attached to the telephone More particularly my invention relates to improvements in telephone head pieces s uch 15, as are worn on the head with ear cups to .fit

- both ears, and'wi'th means for having sounds from a telephone receiver transmitted to" both ear pieces of the head piece I I am not the first, inthis application, to

-:."show and describe a telephone head piece; having earcups to fit both ears and having means for connecting in some manner with a telephone, but in apparatus of this class -.hereto'fore n'iade, 'clitticulty has been expel-'1.-

enced in producing a device which wouldfit. any ordinary head so that the ear pieces wouldfit naturally and comfortably over the ears. Such structures h'ave'been recognized asbeing valuable-because. they-'exclu'de' eitp traneoushsoiinds and enable the slightest sounds through the receiver .to be trans-' mitted to hothear pieces; :Moreover they are-not attached to the telephone',fand that leaves one hand free for making memoranda,

etc

- It is not practically feasible tolprovide for "adjusting the head pieces 'to d fferent" ,'hea d's,because this means complication and -'-,expense, and such devices must be simple, as i' .fr'e'easspos'siblefrom joints, and easy or application without the bother of adju'st- H I I a Qan'y pecul arityottheshape' ofgthe head,"

Thus sounds entering thefbore l'6"o't the-earq'iiece 10 are'a lso'transmitted through the tube'let to'the first ear piece. ,(Thisarrangement 'so" far described is not' 'clairned' as'novel. .Tli'e' ear piece l0 hasl a flangedplate 17 large enough .to receive theen dfof any ordinary -t e l e hone recelver th'eficenterpart 15 pre erably convex, .as "'shon-n fa't {18' sojtha't the telephone rece1ver' when "h'ol (1' against the platel7wil1vnat1irally center itself and bring the bore of the freceiver. oppositethe'hore': I6 of theiear' piece 10% The important .featurebf (the invention,

lies .in. the spring. connection between the.

the ear pieces are held against wabbling and remain firmly inplace. The joints, it will be noticed, connecting the ear pieces and the springforks, permit the ear pieces to turn.

on horizontal axes so as to'adjust themselves in any direction. Thespring forks are provided with flanges 22, a iidThere should be a plurality of these flangeson each fork so that the spring may be held rigidly in one direction, but the flanges are pivoted on the upper ends of a connecting sprmg'QB of a general U shape which fits over some part of the head and which is sufficiently springy to cause the ear pieces to press with 'sufiicient force against the head of the operator to hold the ear pieces 'in'place. It will be seen that the joint betweenthe forks 19 and the spring 23 provides for turning the ear pieces on vertical axes, and thus they can adjust themselves either vertically or laterally, and

will permit the ear pieces to adjust themselves vertically and laterally, outwardly and inwardly, The joints which I have shown connecting the spring forks 19 and the spring 23, hold the forks against doubling over inwardly or outwardly on the spring 23, but permit them to turn laterally.

In Fig. 3 I have shown a modificationin which the ear pieces 10 are similar, and mounted as shown and already described, but in which the tube 14 is divided and connects with a tube 1% through which the sound may come from any source whatever. This form of the device is applicable for use in connection with any other sound prodncing machines for instance for hearing the sounds from a phonograph or other form of musical and talking machine. the apparatus in any case is not strictly limited to use with a telephone, as it can be operated in connection with the conveyance of sound or with any sound producing machine or apparatus where it is desired to have the sound waves accurately and nicely transmitted to both ears and 'where it is desired to have at least one hand left free.

Having thus fully described my inven- In fact tion, I claim as new and desire to secure by Letters Patent:

1. A telephone adjunct comprising ear pieces independent of a telephone but one of which is adapted to abut with the-end of the telephone receiver, a sound transmit ting connection between the two ear pieces, a. tension spring adapted to clamp the ear pieces to the head, and a'flexible connection between the ear pieces and the tension spring which permits the ear piecesto oscillate in one of the ear pieces being provided with a plate to fit against a telephone receiver, and

a sound transmitting connection through the plateto the ear piece, in combination with a curved spring arranged between the ear pieces, and spring forks pivoted on the spring and pivoted also to the ear pieces, whereby the latter can oscillate in two directions.

4.. An apparatus of the kind described, comprising a pair 'of ear pieces having a sound transmitting connection between them, one of the ear pieces being provided with a plate to fit against a telephone receiver, and a sound transmitting connection through the plate to the ear piece, in combination with a spring connection between the ear pieces which permits the latter to tip vertically and laterally.

A telephone adjunct comprising hollow ear pieces having a sound transmitting connection between them, a single curved tension spring arranged adjacent to the ear pieces and spring forks straddling the ear pieces, the said forks being pivoted to the ear pieces at their ends and having their midc le portions journaled to the ends of the tension spring.
