T 0 all idiom it may concern Be it known that l, ESTELLA Sanonas, a citizen oi the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Telephone Attachment, of which the following is a full, clear, and exact description.

The object of the invention is to provide 'a new and improved telephone attachment terial change in the construction of the telephone as now generally furnished by the telephone companies. In order to accomplish the desired result, use is made of a closed diaphragm cap for attachment to the receiver body in lieu of the open cap now generally used, and

tuhula r ear connections extending from the 1 closed cap and ndapted to transmit the; sounds to the users ear." r A practical embodiment of the invention is rei'n'csented in the accompanying draw ions forming-a part of this specification, in which similarcharacters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the improved attachment as applied to the ordinary Bell telephone; Fig. 2 is a sectional side elevation of the manually controlled means for moving the hook into open or closed position and with the receiver in Fig. is a face view of the same with the hook shown in cross section; Fig. t is a perspective vie. of a modified for i of one of the ear :onnections; Fig. 5 is a similar view showing one of the ,a r connections provided with branch tuhes; Fig. 6 is a perspective view of the attachment as applied and showing a modified form ot'the means for opening and closing the receiver circuit; and Fig. '7 is an enlarged sectional side-elevation ot' the said switching i'neans.

The attachment as illustrated in Fig.1

is shown applied to a telephone of the portable type, that is, having stand A carrying a transmitter B and provided with a hook C supporting -a receiver ii. The body of the receiver D is providedivith a closed diaphragm cap E in lieu .of the ordinary apertured diaphragmcap- -now generally.

used, and from thesaidc cl'o'sed diaphragm cap E extends a plurality of ear connections one of which is, in the form of a flexible tube F terminating in branch tubes F provided with removableear buttons 1, and the other car connection is in the form of a rigid tube G made in telescoping sections, of which the end sectioirterminates in an ear drum l adapted to he opened or ciosed by a suitable cover G Both ear connections F and G, are on one and the same closed diaphragm cap E, as shown in the drawings. As shown in Fig. 6 the flexible tube F may terminate in two flexible tubes F provided at their terminals with removable buttons F and mounted on a resilient band F for attachment to the users head to support the buttons in the ears of the user.

in order to transmit the sound from the receiver D through the ear connections to the users ear without removing the receiver 1) from the hook G use is made of means for controlling the transmission circuit. This is preferably done, as shown in Fig 1, by the use of a slide H inthe form of asprin mounted to slide in a slotted guideway attached to the stand A directly below the hook C. The slide 'H is provided with a suitable handle HL tinder-the control of the user of the telephone. The slide lil is normally in lowermost positionso that the hook is in closed positioifas long as the receiver 1) is in position on the hook, but when it is desired to use the telephone by Way of the ear connections and without removing the lever if) from the hook C, it is only necessary for the operator to move the slide H upward so that. the hook C moves into open switching, condition. it will he noticed that When the hook (I is in this position the user of the telephone can either place one or both buttons F into one or both ears or hold the ear close to the drum G to receive the message. .Vhile receiving the message both hands of the user are free for Writing or other purposes. After the conversation is terminated tie operator simply slides the slide H downward back into normal lowermost position so that the hook swings back into open position.

Instead of using a mechanical means for controlling the hook C, use is made of a switch J mounted on the stand A for controlling the electric connection to the hook The switch J is tons J and J mounted to slide in a plate J 3 attached to the stand A, the buttons passing through apertures A in the side wall of the stand to the interior thereof to connect with arms K, K on a three arm lever having an angular arm K fulcrumed at K on the inside of the stand A. The third arm K is pressed on by a spring L and is provided with two pins N and N for controlling .the spring contacts 0, O, O and O of the telephone circuit sothat when the parts are in the position shown in Fig. 7 the call circuit is open to allow of calling the person to the telephone. Now in order to make use of the telephone the operator presses the button J inward so that the switch contact 0 is moved out of engagement with the hook contact 0 and the contact 0 is moved into engagement with the contact 0 to cut out the call circuit and to close the hearing circuit for the hook C and the receiver D without removing the latter from the hook C. When the conversation is terminated, the operator presses the button J to, return the part to the normal dormant position shown in Fig. 7. The spring L is preiti'ably provided with spaced indentations '13, L for engagement with the free end of the arm K provided with two but 1 oi thethree-armed lever to hold the latter in whatever position it is moved into on the operator pressing either button J or J It will be noticed that by the arrangement described the attachment can be readily placed in position on the telephone as now generally; constructed without requiring material alteration or change in the construction of the telephone. It will further be noticed that the attachment is very simple in construction and by its use it enables the user of the telephone to receive a message without removing the ordinary receiver D from the hook C, at the same time allowing the user to utilize both hands for writing or other purposes.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

A telephone attachment, comprising a closed diapl'n'agm cap a plurality of ear connections leading from the said diaphragm cap, one of the said ear connections being flexible and the other formed of rigid telescoping members, and switching means for establishing sound transmission while retaining the receiver in position on its usual support.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ESTELLA SANDERS.
