outer or free end of .eachZsleeve is provided I V with taperedthread as at 13 and each jofthe sleeves are slit axially a portion of the length of he; sleeve on the diametricallylopposed sides thereof as is indicated at 14. a Mounted on the threaded end of each sleeve 11-, 12 is a thumb nut 15, engageable with the slit threaded end thereof. The diameter of J of the sleeves and is horizontally movable with respect thereto, providing tWO'ZtdjUStf ments.- After thestem l6 has been properly 1 adjusted, thezthumb nut 15 may be screwed I upon the tapered threads 13 and by reason of the slit in the threaded portionv ofeach thereto. V

threadslS and is split as at19 in the threaded respect Po ti n the d m ri lly Oppo ite-si es ably anchoredin the opposite side of a pair thereof. A thumb nut 20, having its interior provided with tapered peripheral threads is adapted for engagement with the threaded end 18 of the head 17. A pair of supporting rods indicated generally at 21, 22, have stems 23, 24, extending through each sleeve of the T-shaped members 17 'When the thumb nuts 20 on each sleeve are loose, thestems 23, 24,

- are rotatable and vertically adjustable inthe 10 sleeve. v

To fix the stems 23, 24, the thumb nut 20 is tightened upon the tapered threads, thereby forcing the split end of the T-shaped members together and holding the stems in fixed relation. The lower ends of each part 21, 22, is forked to provide oppositely disposed legs 25, 26, the continuity of which forms a V semi-circular support.

On the free ends of each leg 25, 26are formed a pair of inwardly projecting trunnions 27, 28, which .are rotatforked end flared inwardly provides avery comfortable and light bearing against the ears when the phones are in the listening position. I The ear phones 29 -29 are connected witha suitable conductor wire 30, which leads to the device being listened to, such'as a radio, a telephone or the like. The earphones 29-29 may be of anyconventional type.

,It is to be understood that by describing in detail herein any particular form, structure or arrangement, it is not intended to limit the invention beyond the terms of the several claims, for the requirements of the prior art.

What is'claimed is:

1. A supporting frame for earphonescomprising a-flatresilient metallic band of semicircular configuration, a pair of plates secured to the ends of the band and extending on the opposite sides at right angles thereto, a sleeve secured at its inner end to each end of the band and projecting at rightangles to the head of the user when the band is supported thereon, each sleeve having a threaded yieldable portion on its free end, a T-shaped member having a stem seated in and normally rotatable and horizontally movable with respect to the sleeve, means threadably engageable with the yieldable end of the sleeve for selectively locking the stem with respect to theflsleeve, the head of the T-shapedmember formed of a sleeve, having its upper end threaded and yieldable, a'pair of forked supports, stems on the forked supports rotatably and vertically movable in the sleeves of the T-shaped members, means supported on the yieldable ends of the last-mentioned sleeves for locking the stems of the forked supports in selective position, the forked ends of the forked supports extending inwardly at an inclination to a vertical plane, and a pair of ear phones rotatably mounted in the forked support.

' 2. A supporting frame for ear phones comprising a flat resilient metallic band of semicircular configuration, a pair of plates securedto the ends of the band and extending on the opposite sides at right angles thereto, a sleeve secured at its inner end to each end of the band and projecting at right angles to the head of the user when the band is supported thereon, each sleeve havinga threaded yieldable portion on its free end,xa T-shaped member having a stem seated in and normally rotatable and horizontally movable with respect to the sleeve, means threadably engageable with the yieldable end of the sleeve for selectively locking the stem with respect to the sleeve, the head of the T-shaped member formed of a sleeve, having its upper end threaded and. yieldable, a pair of forked supports, stems on the forked'supports rotatably and vertically movable in the'sleeves of the T-shaped members, means supported on the yieldable ends ofthe last-mentioned sleeves for locking the stems of the forked supports in'selective position, the forked ends of the forked supports extending inwardly at an-inclinationto avertical plane, and a pair of ear phones rotatably mounted in the forked support, the radius ofsaid band being such as to terminate about the ears of the user.

3. In a supporting frame for ear phones comprising a fiat resili'ent metallic band of semi-circular configuration, a pair of plates secured to-the ends of the band and extending on the opposite sides-at right an- 'gles thereto, asleeve secured at its inner end to each end of the band and projecting at right angles to the head of the user when the band is supported thereon, each sleeve having a threaded yieldable portion on its free end, a T-shaped member having a stem seated in and normally rotatable and horizontalmovable with respect to the sleeve, means t readably engageable with the yieldabl'e end of the sleeve for selectively locking the stem with respect to the sleeve, the head of the T-shaped member formed of a sleeve, having its upper end threaded and yieldable, a pair of forked supports, stems on the forked supports rotatably and vertically movable in the sleeves of the T-shaped'members, means supported onthe yieldable ends of the last-mentionedsleeves for locking the stems of the forked supports in selectiveposition, the forked ends of the forked supports extending inwardly at an inclination to a vernate about the ears of the user, the head of the T-shaped member normally disposed in a vertical position laterally of the ears of the user.

i. A supporting frame for ear phones comprising an arcuate band, a sleeve secured at one end to the band and having a threaded yieldable portionon its other end, a U-shaped member having a stem and normally rotatably and longitudinally movable with respect to the sleeve, means threadedly engaged with the yieldable end of the sleeve for selectively locking the stem with respect to the sleeve,. the head ofthe U-shaped member being in the form of a sleeve which has its upper end threaded and yieldable, an ear phone support having a stem extending through the last mentioned sleeve and means supported on the yieldable end of the last mentioned sleeve for locking the stem in selective position.

,7 In testimony whereof I afiix my signature.
