Patented July 30, 1907.

Application iiled September 26, 1904. Serial No. 226,008.

To all whom it may concern:

Be it known that SAMUEL .IAMEs PORT, secretary oi Limited Company, residing at 314 Hag-ley road, Birmingham, in the countyoi Warwick, England, a subject oi the King oi Great Britain, has invented certain new and useiul Improvements in and Relating to Means for Conveying Sounds to the Ears, oi which the following is a specification.

This invention relates to improvements in means for suspending on the ears of an operator sound conducting tubes, and also relates to the particular construction and arrangement ol the tube so suspended.

The invention comprises the production of an ear piece, means for suspending the same in position, and a ilexible tube for conveying sounds to the ear piece.

The invention imther comprises the production of a crank shaped tube adapted to iit into the cavity of the ear, a clip for suspending the same in position, and tubes for conveying sounds from any desired place to the crank shaped member.

The object in view is the provision oi means for conveying sound from any desired point to the ear, and lor suspending the sound conductingmeans upon the ear.

W ith these and other objects in view the invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter described and claimed.

In the accompanying drawingzFigure l. is a plan view oi a sound conducting device formed according to the present invention, the ear pieces being shown in section to better disclose the invention. Fig. 2 is an edge view oi Fig. l. Fig. 3 is an enlarged detail, fragmentary view oi one oi the sound conducting tubes forming part oi the present invention, parts being broken away to better disclose the invention. Fig. 4 is a slightly modified form of my invention, the same bein g shown in section to better disclose the invention.

I provide by my invention a light weight attachment which can be suspended from the ears of an operator for conveying sound from any preferred point to the operator. u

My improved appliance when used by telephone exchange annunciator board operators as asubstitute for the inet-allie head gear and breast plate harness, renders the operation less exhausting and thereiore assist the operator in being continually in that bright, wakeiul and active condition, so necessary in attending to the duties oi' a telephone exchange call-girl.

I will now proceed to describe with reference to the accompanying drawings lthe manner in which the various parts of my invention are constructed, assembled and used.

At the lower end oi the tubes 11e-m, I provide a suspending ring j to which is secured a Y-shaped member d. To the Y-shaped member d is secured a pipe l which is adapted to convey sound l'rom any desired point to the interior of the Y-shaped member d. A suitable binding ring or nut L is provided lor holding the tube l in correct position. Secured to the arms lz oi the Y-shaped member d are flexible tubes ori-m which are adapted to convey sound from the interior of the Y-shaped member d to the crank shaped member or tube e.

The upper ends of the tubes m-m are adapted to receive the end oi the crank shaped member c as clearly seen in Fig. 3 oi the drawing. The member c is threaded at its upper end and has secured thereon an ear cavity nozzle s which is adapted to enter the ear cavity and have the sides thereof iinpinge against the sides ol the ear so as to prevent any sound l'rom entering the ear except that which comes through the tubes m-m and through the aperture in the ear cavity nozzle s. It will be observed that the member e has a deep bend at f in its upper end which permits the device to allow the ear cavity nozzle s to snugly fit in the ear without pressing the lower part oi the ear which will be accommodated in the bent-out portion f.

In order to suspend the member e in proper position for permitting the ear cavity nozzle s to snugly [it in the ear, I provide a clip n. The clip n is preferably made in a loop shape, and is secured to a reciprocating sleeve u. The sleeve u is positioned on the lower part oi the member e and adapted to reciprocate thereon so as to permit the positioning oi the loop it in any desired position ior accommodating various sized ears. A suitable securing means as set screw 13 is used to hold the sleeve u and clip n in proper position alter having been properly adjusted. As seen in Fig. el, I may provide a slightly modified form of means ior conveying sound into the ear. Instead of using the ear cavity nozzle s, I provide cushion o which impinges against the ear and thus prevents any sound from entering the ear cavity except that which passes through the crank shaped member c/. The upper end oi the crank shaped member e/ is threaded similarly to the crank shaped member e ior adjusting the position of the cushion Z, and also the position oi the clip n/. It will be observed that in the modilication shown in Fig. 4 that the clip n is secured to the upper end ol' the crank shaped member e and adapted to be moved back and l'orth for adjusting the same.

In operation the user would suspend the device upon his ears by passing the two ear loops n over his ears, the ear cavity nozzle s would then gently press against the inner surface of the ears, so that sound reaching the member @from the tubular arms m enters the ears ol' the operator. A person by the suspension of the U-shaped frame on his ears, would be able to receive a message, and yet have both hands iree lor use in recording the received message or for other use` i Having now particularly described and ascertained the nature of my said invention, and in what manner the same s to be performed what I claim is;-

1. In a receiver, a rigid tube bent at one end und having its other end Arttztched to a iexible tube which is adapted to communicate with a, receiver'. a rigid clip adapted to pass over and rest upon the ear, said clip being provided with means that is adapted to slide over the rigid tube and is adjustable thereon for holding the end of the rigid tube directly opposite the cavity 0f the eur, and an extension reaching into the cavity of the ear for conveying sound into the inner part of the ear.

2. In a receiver, an ear cushion, an adjustable crankshaped conduit stem passing through said cushion, :t flexible tube connecting said conduit stem and said receiver, and an ear clip adjustably secured to said conduit stem for supporting the same in position.

In testimony whereof I atlix my signature in the presence of two Witnesses.
