Application'filed March 18, 1909. Serial No. 484,933.
To all whom it may concem:
Be it known that I, WILBUR H. THOMP- SON, a citizen of the United States, residin at Wheeling, in the county I of ()hio an State of West Vir inia, have invented cer-' tain new and usefu Im rovements in Telephones, of which the 0 lowing is a specification.-
My invention relates to telephones of. the class in which the receiver and'transmitter are mounted upon opposite ends of a handle, and in such amanner' that they ma be applied simultaneously to the ear an mouth with the use'of but one hand.
The object of my invention is to rovide 1 a device of the character indicated t at will be more convenient to use, and more simple,
compact and inex ensive in constructionv than others hereto ore provided.
The specific feature which renders the telephone especially convenient. in use is a.
handle that is capable of being bent'into,
and of thereafter remaining in, any one of a variety of forms, and that, therefore, permits the adjustment of the receiver and transmitter to any useful positions relative to each other.
The device is rendered simple, compact and inexpensive inconstruction by certain other structural features that will be hereinafter more fully pointed out.
The invention is illustrated in the accomanying dra'wing, Figure 1 of which is a ront face view of a telephone constructed in accordance therewith, some of the parts bein broken awa for the sake of clearness of ustration. ig. 2 isa back face view of the device, Fig. 3 is a side view' thereof with the receiver and transmitter adjusted to one of the most commonly useful relative positions, and Fig. 4 is a sectional view of a modification of the handle of the telephone.
Mounted upon opposite ends of a handle 1 are a receiver 2 and a transmitter 3, the operatin parts of which are of any usual or desire construction, and are inclosed within shells or casings, each com rising two parts 4 and 5 that are telescopeci and suitably securedtogether, the back shell parts 4 being provided with flat circular bases 6. The handle 1, comprises a'main intermediate portion that is capable of being bent into, and of thereafter remammg 1n, any one of a variet of forms, and to this end it may convemently consist of liable tubing, like that illustrated, and suc as is often used for suitable material.- To the ends of the pliable portion of the handle are secured two tubular members 7 and 8 that are partially or almost wholly flattened, the flattened portio'ns formin seats for, and being respectively secured by means of rivets and screws 9, or otherwise, to the flat base portion of the receiver and transmitter. The end member 7 is extended somewhat beyond the receiver 2. and is slotted to ermit of han ing the telephone upon a 00k or a hoo switch. The telephone is connected to the line by means of conductors 10, and the receiver and transmitter are connected together by conductors 11, that project through holes in the parts 4 and in the unflattened portions of the end member 7 and 8 of the handle, and that extend through the handle which sheathe's and protects them. In some instances it may be desirable to utilize the handle as one of the conductors connectin the receiver and transmitter,
'and in t at event therewill be but one other conductor inclosed by the handle, as shown in Fig. 4. M
The telephone may be used in connection with an ordinary hookswitch, but I prefer toe render it independent of a hook switch, and accordingly mount members 12 and 13 within the receiver casing, and rovide a button 14 that projects through t e casing and is adapted, when pressed inwardly, to efi'ect engagement of the switch members piping gas, or it may consist of any other and completion of the ringing and talking circuit.
In'the use of the telephone the operator may adjust the receiver and transmitter to any desired or convenient positions relative to each other by simply bending the handle, which thereafter maintains the said parts in the relation to which they have been adjusted. In order to call the central office and to talk to a distant party, it is only necessary to press the button 14 with the thumb or finger of the hand used-for holding the telephone in roximit to the ear and the mouth. H
he plia ility of the handle, which permits each operator ,to adjust the positions of the receiver and transmitter to his own convenience, is regarded as a novel and specially useful feature, while the. provision of casings for the receiver and transmitter having flat or plane base'portions that are seated a ainst, and secured to, the. flattened portlons of the tubular end members of the 1. In a hand telephone, the combination with a receiver and a transmitter, of a bane dle therefor composed of tubing and com:
prising a pliable central member and solid" 10 end members secured thereto that are partially compressed to provide flattened pore tions to which the receiver and transmitter are respectively secured.
2. In a hand telephone, the combination 15 with a' receiver and a transmitter, of a handle therefor composed of tubing and comprising a pliable central member and solid end members secured thereto-that are partially compressed to provide flattened ortions to w ich the receiver and'transmltter 2b are respectively secured, and an insulated conductor extending through the handle and electrically connecting the receiver and transmitter. I In testimony whereof, I have hereunto 5 subscribed my name thiseleventh day of March, 1909.
