WITNESSES: INVENTORS wafiw ATTORNEY WTEE STATES PATENT @FFTGE.
PETER L. JENSEN AND EDWIN S. PRIDHAM, OF NAPA, CALIFORNIA, ASSIC'NORS TO COMMERCIAL WIRELESS & DEVELOPMENT 00., 'OF SAN FRANCISCO, CALIFORNIA,
A CORPORATION OF ARIZONA.
TELEPHONE To all whom it may concern Be it known that we, PETER a subject of the King of Denmark, and ED- WIN S. PRIDI-IAM, a citizen of the United States, both residing at Napa, in the county of Napa and State of California, have invented new and useful Improvements in Telephone Sets, of which the following is a provide a practical commercial telephone set to be used when it is not convenient to hold the receiver to the ear.
The invention consists of the parts and the combination and construction of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is an elevation in partial section of a telephone set representing the invention, and with the adjustable hollow arm out of use position. Fig. 2 is a view of the arrangement showing the hollow arm in use position.
Referring to the drawings, 2 is the sound box of a telephone receiver of the type wherein a freely movable coil is disposed in strong magnetic field, the diaphragm of the receiver being rigidly attached to the coil. It is to be understood'however, that we do not limit ourselves to the type shown.
3 is the diaphragm of the sound box. This diaphragm byits position divides the sound box into air chambers 45 from ,which are respectively led two sound conveying tubes 67.
8 is a hollow handle made of rigid tubing equipped with a suitable holding grip. The grip is adapted to be held in rest position by the forked hook switch as indicated at 9-9 similarly as shown in our copending application No. 787 ,945, above referred to. The placing of the handle upon the hook or removing it controls the connection of the instrument to the line as in ordinary tele-.
phone practice. The hollow handle 8 is connected by a flexible tube 10 to the tube 6 leading to the sound box 2. The other end Specification of Letters Patent.

Application filed April 27, 1914. Serial No. 834,699.
of the handle 8 terminates in the 'earpiece 11.
Mounted on the handle 8 at a proper distance from the ear-piece 11 is the transmitter 12 which by proper connections is adapted to be included in the telephone circuit. In receiving telephone messages it is a well known fact that a great improvement in reception is obtained by listening with both ears. This method is generally practised in wireless telegraphy and in train despatching, but has'seldom been used in or dinary commercial telephony. With the mcreasing use of the telephone for long distance communication it is Very necessary that every advantage leading to better reception be taken. For this reason we have designed a telephone set which is exceptionally successful for long distance work, both in transmitting and reception. In mounting the transmitter on the hollow handle 8 at a proper distance from the earpiece 11 the user is constrained to talk correctly into the transmitter which of itself is of great value in telephony and especially so in long distance communication. In orderthat listening with both ears may be conveniently accomplished, we have mounted upon the handle 8 a light adjustable listening tube or hollow arm 13.. One end of this adjustable arm is connected to the tube 7, leading to the sound box 2, by the flexible tube 14. The other end terminates in the ear-piece 15. This hollow arm consists of two sections, one fixed in position in relation with the hollow handle 8, and the other movable through an angular displace 'ment about the joint 16, and carrying the ear-piece 15. Between the sections there is Fi g. 1, the movable section carrying the earpiece 15 is held back out of the way;'while in use the action of the spring tends, as indicated in Fig. 2, to press the ear-piece 15 firmly against the ear. In other words, the jointed arm 13 swings through an arc approximately 180? about its pivot 16, so that if one does not want to use it, it can be swung out of the way and remain there, as indicated in Fig. 1, even when the instrument is in use. A further adjustment of this listening tube is obtained by the adjustable mounting of the earpiece 1 5,. A ball 18 through which a hole hasbeen drilled is fitted to the end of the movable section. A socket 19 is fitted over the ball so as to move with a rather stifi action, and to this ear-piece 11 is placed to the ear and the transmitter is held in the proper position for good articulation, then the movable section of the hollow arm is swung around pivot 16 bringing it into use position, and
the ear-piece 15 is adjusted to the other ear. When through talking the movable arm section is folded back and the handle is replaced on the switch hook, thereby disconnecting the transmitter from the line.
Having thus described our invention what we claim and desire to secure by Letters Patent is- 1. In a telephone set, including a normally immovable receiver, an operating device comprising a hollow handle terminating in an ear piece and adjustable upon a hook switch, a transmitter mouth piece mounted on said hollow handle, an adjustable hollow arm with an ear piece connected to said handle, and flexible tubing connecting the sound box of said receiver to said hollow handle and hollow arm whereby the operation of said receiver may be heard, said tubing permitting said hollow handle to be placed upon or removed from said switch hook, thereby controlling the circuits of said set and allowing free universal movement of the ear pieces as to the relatively stationary receiver.
2. In a telephone set, the combination with a movable hollow handle upon which is mounted the transmitter of said set, said hollow handle being connected to the sound box of the receiver of said set by a flexible tube and said hollow handle terminating in an ear-piece, of an adjustable hollow arm said adjustable hollow arm being mounted upon said hollow handle, one end of said hollow arm terminating in an ear-piece, the other end of said arm being connected to the sound box of said receiver by a flexible tube.
3. In a telephoneset, comprising a transmitter, a receiver and a hookswitch, said receiv r being provided with a sound box, said transmitter being mounted upon a hollow handle, an adjustable hollow arm, said hollow arm being mounted upon said hollow handle, said hollow arm being made in two sections connected together by a' oint, one of sald sections bemg fixed in relation with said hollow handle, the other section being movable through an angle about said fixed section by the action of said joint, said movable section being equipped with an adjustable ear-piece and said fixed section being connected by a flexible tube to the sound box of said receiver, and a spring connection between said fixed section and said movable section by virtue of which said movable section is held in proper position, substantially as described.
In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
