To all whom it may concern:

Be it known thatI JOHN S. TxMMoNs, a citizen of the United tates, residing in New York city, in the State of New York, have invented the Telephone, of which the following is a specification.

One ob'ect of this invention is to provide a relativel simple, compact and inexpensive form of te ephone whereby sounds produced by a telephone receiver of any of the ordinary forms in common use may be mao'nb lied or amplified so as'to be clearly audlble at a distance fromlthe instrument ;-the inbody of the horn formed vention contemplating a novel form of combined telephone support and horn particularly adapted for use with a receiver supported byva hook or bracket in the customa manner.

ese objects and other advantageous ends I attain as hereinafter set forth, reference being had to the accompanying drawings, in which,

Figures 1 and 2 are res a front elevation of'a te constructed in tion;

Fig. 3 is a front elevation partly in vertical section illustrating a slightly modified form of the invention; and

Fig/1 is a front elevation of the invention applled to a box telephone.

n Figs. 1 and 2 of the above drawin 1 represents al telephone base o r stand o the general form in common use although preferably somewhat more conical in outline. This stand 1 is hollow and as shown in Fig. 1, its conical cavity communicates at the upper or small end with an open end, lateral extension 5 projecting horizontally si as to constitute in effect a continuation f the by the main porctively a side and ephone instrument accordance with my invention of the stand.

A transmitter 2 of any desired construction is pivotally or otherwise mounted on the upper portion of the stand which in that form of the invention shown in Figs. 1 and 2, has a holder 13 formed by three fingers whereb atelephone receiver 3 may be normally t ough removably supported. The tubular extension 5 of the stand is so positioned thatits o n or inlet end terminates at one side of t is holder in such position that when the receiver 3 rests .in the latter, it 1s substentllly @mutue with Said open end and an annular portion ofits face sur rounding the opening to its diaphragm edh gaes the edges of said extension.

'Ihe receiver is electrically connected through the customary cord 14 with the terminals whereb the instrument is connected to the line, w ich terminals, in accordance with my invention, may be mounted on a base plate 15 within' the hollow interior of the stand l or at any other suitable point and said stand has 'a series of openings 6 through the sides'of its flared end immediately adjacent the base plate to permit of the escape `of the sound waves from its interior.

With the above described arrangement of parts, the receiver is so connected as to vbe at all times included in the line circuit, so that when it is desired to utilize the instrument, the voice of a person speaking into the transmitter of a sendin instrument will at any time energize the laphragm of the receiver. By reason however, of the roX- imity of the end 5 of the horn to sai diaphragm, the Voice of the person calling will be greatly magnified so as to be audible at a distance from the instrument. Thereafter the receiver 5 'ma be removed from its holder 4 and the te ephone used in the ordinaly manner, the receiver being returned to sai holder at the termination of such use with its opening or diaphragm immediately adjacent the inlet end of the horn exten sion 5.

In that form of my invention shown in Fig. 3 I have as before so formed the main portion of the base structurel ofavtelephone stand as to provide a conicalor taperlng horn chamber. In this instance however, I have also provided a tapering conduit 10 whose larger end extends up into the hollow interior of the stand, which is so formed as to reflect sound waves delivered to it from said conduit and amplify them asbefore so as to materiell increase their intensity. The smaller endyof said conduit 10 is extended through.Y the side of the stand and is turned upwardly into a position substantially coaxlaln with a telephone receiver 9 sup rted ona hook 16 carried by said stand int e well known manner. The transmitter 2 is likewise mounted as usual `on the u per -end of the stand. The upturned end o the conduit 10, as well as the openend, of the Patented July 19, 1921. i

extension 5 (Figs. 1 and 2) are preferably provided with an end or mouth piece 17 of Iiexible material such as rubber so that they mayclose-lvgthough yieldingly engage the receivefaniE insure the passage of sound waves therefrom into the horn provided by the stand.

In that form of my invention shown in Fig. 4, I have mounted a horn structure 11 so that it extends transversely through the box 12 of a Well known form of telephone instrument in which the transmitter 2 is mounted on the door or front 18 While the receiver 9 is removably supported on a hook 16 projecting'froni one side. The small end of the horn structure 11 in this ease projects from one side of the box and is turned up into position so that its mouth piece 17 will contact with the open end of the receiver 9 when this is hung from the hook in the Well known manner. In thisI case as Well as in all of the others above described, the receiver and transmitter are both constructed, mounted and capable of use in the or inary manner, while the receiver-supporting structure is so modied as to itself form or I horn provided by the supportin rovide a tapering chamber constituting a horn Whose small or inlet end terminates immediately adjacent the open or diaphragm end of the receiver when this is supported in its normal o r idle position not in use. Said receiver, being at all times included in the line circuit, Will coact with the structure or stand to so magnify the soun s from the `receiveras to cause these to be clearly heard at a distance from the instrument'.

Obviously it is inunaterial as to Whether the stand upon which "the telephone apparatus'is mountedis designed primarily as part of such apparatus'or Whether it in addition possesses other'u'seful or ornamental functions s uch asthaty of supporting a lamp structure or the like,`sin'ce in any case my invention contemplates the vcombination of a supporting stand formed to serve as a sound ampliiier or horn,' with atran'smitter carried "by `the standY and aV receiver remc'vably mounted on saidv stand in position to utilize its sound amplifying quality.

I claim: Y

1. The combination in a telephone instiumentof a'hollow substantially conical supporting 2 structure having an inlet opening forit's small end; at smitt'er mounted on s'ald structure; andjiafreceiver removably vcarried b'yf-the'strnetlire with its diaphragm vconstitute a telephone stand; a transmitter mounted on the horn; a receiver; and means on the horn for removably supporting the vreceiver with its diaphragm immediately adjacent the inlet end-thereof.

SQThe combination of a telephone support in the shape of a casing formed with a tapering chamber and including a projecting tubular portion constituting the small or inlet end of said chamber; a transmitter; and a receiver removably carried by the support with its diaphragm immediately adjacent the open end of the tubular projecting portion of the support.

4. The combination of a telephone stand having a cavity of generally conical form and mounted with its larger end downward, said stand having an opening into the small end of its conical cavity; a transmitter carried by said stand; and a receiver removably supported by the stand with its opening or diaphragm immediately adjacent the opening into the small end of the cavity thereof.

5. The combination of a telephone stand having a flaring base and formed with a tapering hollow interior having openings through said base, the stand having also an open end lateral projection forming a continuation of its hollow interior; a transmitter mounted on the stand; and a receiver removably carried by the stand with its diaphragm nnrmally immediately adjacent the opening into said lateral projection.

(i. The combination of a telephone stand having a substantially conical form and provided With a tapering chamber; a tapering conduit havingts' small end extending outside oi' the stand and its larger end terminating adjacent the small end of the tapering chamber; a transmitter carried by the stand; and a receiver removably supported by the stand with its open face in substantial engagement Witli the small end of the tapering conduit,

`7. The combination With the receiver and the transmitter of a telephone of a hollow stand for supporting the same; with means connecting the receiver independently of the transmitter with said stand for utilizing the JOHN s. 'riMMoNs ,t latter as a horn to magnify sounds produced
