. DALL, a citizen of the United States of iceiveurs, of which-the following isa specifi cation. A l
America, residing at Boston, in the county of Suffolk and State of Massachusetts, haveL invented certain new and useful Iinprove ments in Head-Supports for -TelephonejRe- 1 rlhis invention relates to head supports for telephone'receiverssuch as are customlarily iisedby operatives, receiving such al number ,of messages as to need the receiver lor receiversnearthe ear, at all times.
ther development of the idea contained in -Patent Number 1,087 ,704, issued to me on February 17, 1914,l and in mypending application, Serial Number 813,165, filed Jan- ,nary 20,' 1914-; both for head supports for.
telephone receivers. p
. The objects of the invention are to lprovide va support of simple and cheap construction, having asmall number of sepa,-
rate parts so as to`facilitate the assembling of the device. To provide a support in which the receiver will be verti ly adjustablel sol as toV contact the ear of dierent users;v inv which the receiver will have a swivel adjustmentvso asjto conform to the contour of the ear; and in which the receiver will have a resiliently retained hori zontal adjustment to permitthe same to approach-or recede from the ear, as the volume and character ofthe transmitted sound may require.
' broken side' elevation of a receiver showing Fig. 2 is a side elevation thereof.- Fig. 3 is a side elevation of a receiver showing.v in' 'detail' a modified form of resilient retaining means,'and swivel connection. Fig. 4 is a in detail a modification of the vertical justing means. Fig. 5 is a rear elevation thereof. Fig. 6- is a front elevation of -a modified forni of the head support. Fig. `7

The present invention constitutes a .fur-' accompanying drawings,
Patented Jan. 4, 1916.
iS- a side elevatioiithereof. Fig. 8 is a front elevation of a head support showing a further modiication of the support shown in Fig. 6. l
ReferringV to said drawings by numerals:-A suitably curved liead-band is composed of two similar arc shaped sections 1,- adapted to overlap 'for-a portion of their length-and to be retained by sleeves 2 which embracesaid sections at their over' lapped -portion and in which said sections have a`close` sliding lit. Y
The head-band sections 1 are provided, at
a' suitable point, with the integral, laterally extending ears, or wings 3, curved toY conform to the side of the head and positioned .to engage the head, above the-ears. The purpose of said ears, or wings 3 being to retain the band more firmly in place and'at the same time relieve the pressure ofthe band upon the head by distributing the same over a,- greater area.
The'free ends of sections 1 are turned outwardly at practically right angles, to form receiver supporting members 4, the said' niember's 4 being provided with angularly disposed ends 5, for the purpose of limit-v ing the swivel movement of the receivers as hereinafter more fully set forth.
,iiisuitable opening 6 is formed in supporting members 4 for thev reception of a Screw 7, which fits loosely in said opening,
and is provided with a head of substantially heinispherical form, the curvedl siirfface of said head forming the bearing surface thereof.` `Screw 7 is adapted to engage a j convex `projection 8,' which is drilled vand tappedforthat purpose, formed on a receiver holding ring or band 9. Band 9 has an L shaped. arm 10 projecting from the edge thereof, said armbeing provided'in its .downwardly projecting leg with an aperture adapted to receive a threaded stud 1'1 carried by the back ,of the receiver case 1 2.'
Receiver case 12 is slidably mounted in ring or bandV 9 and has, interposed between the back thereof and the downwardlyprojecting leg of member 10, a resilient member,
by pre-ference thespiral springi 13, surrounding the aforesaid stud 11. Aknurled thumb nut 14 is adapted to engage the stud 11 for the purpose of sliding the receiver v'back and forth through the ring or band 9 against the action of spring 13 by screw- I ing said nut 14 on or', od, thereby causing 11o Vpiecehead-band 1 has adjustably secured 1 4 agree/,eea
' the receiver to approach .or be withdrawn from the ear of the operative.
Referring more particularly to Fig. 3, it will be seen that, in place of the Iscrew 7, a threaded pin or stud 7 may be carried by the band 9 and a nut, such as the globular nut l5, here shown, provided to engage the lstud 7 for the purpose of swivelng the. `In this figure is also receiver in place. showna modification of theresilient member; the curved spring 13 being. here substitutedfor the spiral spring 13.
In Figs. land 5 is shown a further modiication wherein the usual one piece head- 'band-1l is used, having adjustably secured tothe ends thereof, throughbolts 16 and nuts 17, the extension members 18 provided with a. longitudinal slot'19 for the purpose of allo-wing vertical adjustment. The ends `of 'said members 18 are angularly disposed to form receiver supporting members 4 the formv of which and connections to Which.
are the same as'. heretofore described.
A further modification of the device is shown in Figs. 6,7 and 8, wherein the one thereto, by'means of the bolts 16 and nuts 17, the resilient straps or bands 20, provided with longitudinal slots 21 for-the purpose of permitting 'vertical adjustment thereof. Lugs 22 are provided on straps or bands 20, said lugs being centrally bored and tapped .to receive `the thumb-screws 28.A As will be readily understood, the ends of thumbscrews 23 impinging upon head-band l causes ,straps or bands 20 to approach or recede from head-band 1` vthereby causing a horizontal adjustment of the receivers. Suitably secured to the free, ends of bands or straps 20- are outwardly projecting, bifurcated, members 24, between the prongs of which. are placed spherical members 25.
' Said' prongs being counter sunk on ,their inner faces to-form a socket for said spherical members. Suitably secured to spherical members,25lis a pinor stud 26, passing through an opening 27formed in one prong of bifurcated members 24, and having its lower end secured, in any suitable and convenient manner, to a foot piece 2S carried by 'the receiver `casing12.` The. prongs of bifurcated members 24 are drilled and tapped 'to receive the adjusting screws 29, by means of 'which the tension on spherical member 25, may be regulated.
The modification shown in Fig. 8 isin all respects similar to that just described with the exception, that the slotted portion of straps or bands QO'are adapted to overlap and be retained by the one bolt 16 and nut 17. `When using my invention the band is placed in position over the head and -the receivers brought into position to Contact the ears by sliding the band sections'l back and forththrough sleeves 2, or when using a modiiication, by loosening nutv17 .and sliding the receiver carrying member up or down yuntil the desired positionis obtained. This gives the vertical adjustment which is so necessary in devices of this character. Because of the swivel connection between the receiver and head-band the receiver will conform to the contour of the ear, but will 'be limited in its outward swing by the down turned ends 5 coming in contact with the arm 10. c
IVhen adjustment toward or away from the ear is required; that is, horizontal adjustment ofthe receivers; a turn of the` said head band, means carried by said-head band for. vertically adjusting said receivers,
and resiliently retained, screw operated means for causing said receivers to approach or recede fromthe ears. i
2. In a head-support for telephone receivers, a head band,- receivers secured to said head band,` and Screws which adjust said receivers horizontally.
In a head support for telephone re- ,I celvers, a head band, receivers secured to said head band, and screws which Vadjust said receivers toward and awa-y from the ears. n
4. In a headxsupport for telephone receivers, a head band, resilient members adjustably secured to said head-band,receiv ers carried by said members, and screws, carried by said members and engagingA said band, which adjust the receivers toward and away from the` head.
In testimony whereof I hereunto aHiX my 1 signature in presence of two witnesses". i' n CHARLES ADAMS-RANDALIL` Witnesses:
