TELEPHONIC APPARATUS.
Specification of Letters Patent.
raeeated sept. i5, isos.
Application filed April 5, 1907. Serial No. 366,594.
.To all whom fit-may concern.'
Be it known that I, FRANK I/V. `WOoD, a citizen ofthe United States, residing at Newport News, in the county of Warwick and tate of Virginia, have invented new and useful Improvements in rlelephonic Apparatus, of which the following is a specification'.
This invention relates to telephonie apparatus, and more particularly to apparatus of this character designed for use on shipboard Where certain contingencies arise that have to be met in the successful use of the telephone which do not present themselves in the operation of the instrument on land.'
he primary object of the invention is to provide a telephonie apparatus of compact and serviceable construction, which shall be practically proof against injury. by water,
- dust, smoke or other usual agencies. 20
A further object ofthe invention is to provide a portable telephone set in which the use of head gear is entirely eliminated and the usual objections to this Vclass of apparatus thereby overcome.
With the above and other objects in view the invention consists of the construction hereinafter described and illustrated in the accompanying drawings, in Whichzl Figure 1 is a view showing the complete portable apparatus in position. Fig. 2 is a plan view ofthe casing thereof with the cover removed. Fig. 3, is a central vertical'sec-n tion through the same. Fig. 4 is a side elevation ofthe casing and attached parts. Fig. 5 is a sectional view ofthe ear-piece and con necting tube. Fig. 6 is -a plan view, with cover removed, of a complete apparatus designed for stationary use. Fig. 7 is a lan view of the receiver magnet, and case. Fig. 8
is a central section oi the cup shaped disk,
constituting the case. Fig. 9 1s a central sectionon line 9-9 of Fig. 6. Fig. 10 is a central section on line 10-1() of Fig. 6.
On shipboard it is often the practice to- 'wire the entire ship for a telephone system and to provide at suitable locations sockets into which suitable plugs attached to a telephone instrunient.may be insertedand the user thereby enabled to communicate with the centralfoi'iice or different parts of the ship. In this way the' oilicer in charge may communicate, say `with the engineer from a number of diil'ercut points, and thus the necessity for providing a large number of tele phone sets is avoided.
Referring to the drawings in detail, my imn proved portable apparatus comprises a cas-A ing 1 of substantially cylindrical shape provided withends 2 and 3. The end 2 is attached thereto,. and preferably formed integral therewith is a series of lugs 4 havifng per forations adapted to receive snap hooks 4S, attached to straps 49, 50, secured around the body ofthe user as clearly shown in Fig. 1. The straps 49 and 50, are provided with slide buckles 51, whereby they may be adjusted to the proper length.
/' The cylinder 1 is provided at diametrically 'opposite' points with bosses 5 and extending across the inside of the cylinder parallel with the ends is a partition 6, having formed integral therewith sleeves 7 extending toward said bosses and arranged in 4line therewith. The sleeves and partition serve to divide the casing into two compartments, in one of `which is located the transmitter, and in the other of which is located the receiver, the arrangement being suoli that the compartment containing the receiver communicates through an opening in the partition with the sleeves 7, while the com artment containing the transmitter is eiitire y closed.
Fitting into the sleeves 7 an'djournaled therein are extensions 8, formed on the end of hollow receiver arms 9. These arms 9 are provided with radial flanges 10 swiveled in the1bosses 5, above described, and a plate 11 overlies the flanges 1() and is secured to the bosses. By this arrangement it will be seen thatthe receiver arms can turn freely, the flanges 10 turning under the plate 11 and the ends 8 turning ,in the sleeves 7.
Surrounding the outer end 12 ol each receiver arm and resting against an annular shoulder 13 formed thereon is a ilexible tube 14 formed of a Acoil of spring steel wire and this tube embraces at its other end a flange 15 formed on the ear-piece 17. The carn piece 17 is provided around its outer periphery with a cushion 19 of soft rubber or other suitable material which is adapted to lit snugly avainstthe ear of the user and thereby exclude external sounds. 'Arranged within the tube 14 is a second flexible tube l5,
lwhich conducts the sound from the receiver arm to the ear-piece. It will thus be seen lili;
that owing to the resilience of the tubes 14 the earieces will be held irmly against the.
ears of t e user and the necessity 'for employing head gear or clamps of any kind is'entirely avoided.
Also formed integral with the casing 1 is a boss'20 provided with-a gland 21 ada ted to 25 formed *on-the member 3 (see Fig. 3) and is surrounded by an under-cut ring 23 secured to said member 3. A split ring 24 is adapted to enter a groove in the member 22 l `,sand to underlie the ring 23, thereby securing "the member 22 'nl place and forming a substantially water-tight joint, while, at the' same time, perniitting the mouth-piece to swivel freely in the casing.
lmmediately under the mouth-piece is disposed a dia hragm 26 formed of copper foil, mica. or cel uloid and-which is designed to protect the working diaphragm 27, frommoisture or foreign material. The working diaphragm 27 1s preferably formed of alum1- num and is disposed immediately beneath fthe diaphragm 2- and is preferably' secured thereto. A ring 2S serves to support the two diaphragme and hold them in position. The working diaphragm 27 eoperateswith the pin 30, connected with the transmitter 29 as in the usual construction. This transmitter is supported by a bar 29' carrying binding posts 29 a, as clearly shown in Fig. l0.
31 indicates the receiver magnet coils, which arc wound upon cores 32, secured to the two permanent magnets 36, as shown in Fig.l 7.V These magnets consist of superposed lamina?, and are mounted in a cup shaped disk or case, 35, which is secured into the casing, and thus serves to support the receiver. The case 35, is provided with openings 35 through which the wires extend. These wires then pass upwardly through a conduit la (shown in 'Fig-3) formed in the walls ofthe casing 1, and pass thence to suitable binding posts 29 1n the transmitter compartment. From this compartment, the
wires extend. out through the packing gland' -,21. neeting strips 38, held by binding screws 37.
seaeeo .Mounted inside of the casing are a pair of contacts 40 carried by a block of insulation 41. And a shank 42 attached y-to a push button 43 is adapted to abut against one of these contacts 40 and to close the circuit between them when displaced. These con-v tacts control the talking` circuit of the instrument. A diaphra rn 44 preferably of soft rubber surrounds t e push button 43 and is attached thereto at its center, while its outer edge is secured to the casing by means of a gland 45 screwed down over a boss on the casing. By this construction l provide an absolutely water-tight joint "where the push button asses through the casing so as to exclude ail dampness and foreign matter from the. casing. l
In practice the user inserts his plug 37 into the'most accessible socket and having thus callcd'the arty he desires to' communicate with, he ho ds the button 43 and thus estat. lishes and maintains the talking circuit while carrying on the conversation.
ln Figs. 6, 9, and 10 l have shown a slightly modified form of apparatus adapted for use as a stationary or bulirhead telephone set. ln this form, l provide an ordinary mouth piece 22' screwed i'nto the top 3a of the" casing 1'. The construction of the transmitter and receiver, and their arrangement, is the same as above described. There. is, however, in this modication, but one ear piece, 17', and this is carried at the end of a' rigid receiver arm 9', swiveled in the casing 1', by means of the flange 10, and overlying 100 plate 11. A set screw 10' underlies this plate 1l, and bears against the case 3.5.
The casing 1', has a artition 6', provided with a sleeve, 7', in W ich is journaled the hollow extension 8', of the receiver arm 9'. 105
Fitted'in'to the eri'd of this extension 8', and secured by means of a screw 41a, is a block 41' of insulation, such as' hard rubber or fiber, having a semicylindrical cam projection. Disposed adjacent this cam shaped projection are the ends of two contact springs 40' of the form shown in Fig. 6, secured to the casing at their other end by means of screws 46. A pipe conduit, 20a
screws into a boss 20', formed on the casing 115 1', and protects the outgoing wires.
Formed in the extension 8' is a circular opening 8u, clearly shown in Fi s. 9 and 10.
The drawing shows the norma position of the arts, with the receiver arm hanging ver- 120 the cam projection on the hlock-41' engages 130 y and forwardly, thus roseaeeo the lowericontact spring and forces it'u'pward against the upper spring,
. in the art.
- cut away, if necessark lt isobvious that, if desired, the construe? tion of circuit controller shown in Figs. 6 and 9 may be employed to equal advantage in the forni of apparatus shown in Fi s. 2 and 3. ln this case, of course, the push utton 43, would be omitted, and a cam projection tted to one of the extensions 8, the sleeve, 7 ,being contactlsprings.
What I claim is 1. A telephone` Vapparatus comprisin a i transmitter and a receiver, a casing incosmg -the saine, and providedl with .substanf 'tialiy lat, '.opposingends, one of which. is j adapted to rest against the body of the user, a
