n.1. on :EvAN-sroit,

Be' it (known 'that We, ALEXANDER Mnnn andVv DONALD Hf' Svvnnryresidingjat Villa' larln in. the County? O D'l-Pgwdi State. of' Illinoigi; and' at' Evanston, nthe' county O'Cookand' Stat-'enfv illinois, responfor'the Vconvenience 'of 'the user Ain" drawing thertelephone instrument toward him for use and pushing it away when' it is not Wanted.

One 'object of the invention lis to eliminate' unnecessary' ymovement'l in; usingY telephones, especially those Which are movablyinounted on extensible supportsfto' bev 4drawn"towards the `user When in use.

Another object is toi call the operator automatically when sucha telephone isdrawn tovfards the user, independent' of any Inanipulationgothe .ear piece. Another :object is to bringtlre telephone' and ear pieceboth' into operative'juxtaposition Withthe mouth and ear respectively of the `user by a single simple movement of one hand only, leaving the otherhand Yentirely free atall timesto Write down memorandal or for Manyother purpose.r f

Anotherobj'ect is to leave both handsen` tirely free' while conversing overI the telephone.

Further objects and advantages of vthe in-l vention will become apparent as the description proceeds,

In the accompanying drawings a'v Figure l is a side elevation, and

Fig. 2 isiA apartial plan view-of an illustrative embodiment of the invention; and

Fig. 3 is a detail of the clamp for the ear piece Support.

In the embodiment of the invention selected for illustration, We have shown an ordinary desk telephone comprising a base 10, a standard l2 and a mouth piece 14. The usual hook 16 is provided, adapted to connect and disconnect the electric circuit' through the instrument. Ordinarily this is accomplished' the hookf'do'vvn' i with"thewveightfofthe' earpiece, or by yre'- moving the ear piece vto let the hook iiy up' under' thev action of a suitable spring (not shown) Various tyres' of eXtensible linkages" ate' employed'for the'iconvenience ofthe users' of such telephones; XVehave illustrated 'a standard '18 supported by anv eXtensible' Alink- '.20 in this` 'instance of 'the lazy-tongs variety.V `racket `22 gripsf'standardslS and 12 to` fasten' themtogether'.y According to 'the "present 'invent-ion `suitable means are provided for supporting the ear'piece'-24 at all'times'insuolr` a position thatl whenV the user istalki'ng into-` mouth piece 14 his ear Will be' conveniently junta-VK posed1to.` the ear' piece 24. Vtehaveillus: trated-'a standard 26 mounted on bracket 22 byV means. of bolt 28 having a, transverse' l i slotted' hole fto receive the standard: A 'Washer 30 is provided; Withlarcuate Anotches at132'to "fit standard. 26 and lock nut- -34'z Will force'standardA against Washer 30 andA Washer 'SO againstf 'bracket '22," to f hold Ythe parts yin juxtaposition lbyl friction. i When freely about-y its oi'vn axis, and standard '26 cangslidethrough'A thebolt andalso rotate about itsoWnfaXisf*Receiver 24fis-attached mea'ns'oil set' screu7 40;" I n'thi'svvay complete adjt'ist-ment'vo earpiecel 24 tothe precise position required by the-physicalicharacteristics of the user is provided. Y

Rod 26 is bent at ri. ;ht z tnglesiatthel bottomasat162i and terminates in lan eye G4 connected by linkfltor the intermediate' pivot 68 .o;t;linl.44.v `NVhen the telephone is lpushed backI the ear p iecelvvill-swing.l aromi'dvout ofV the fvvay,.and When the parts are pulled out it will swing fonwvafrd r intoA operative positionilt will beiobvious that the means :fory moving the ear pieces in and out may be omitted if desired.

Suitable means Aassociated With the eX- tensible` support are provided for automatically permitting hook 16 to rise When the instrument is drawn toward the user. `With a linkage type of eXtensible support, this means may conveniently comprise a single piece of spring Wire extending through the pivotal connection at 42 belCO tween standard 18 and link 44 of the linkage. One end of the wire extends upward to pass through one of the other pivots 46 of link 44, whereby the wire tends to rotate about point 42 as a pivot when the linkage is expanded. From pivot 42 the other end of the wire extends in any suitable or convenient way to terminate in a hook '48 overlying the narrow portion of hook 16. As this hook moves about point 42 of the center, its outer end 50 should preferably be curved substantially in the arc of a circle around point 42. In the embodiment shown, slight additional resilience is provided in the wire by extending it forward as at 52 then laterally as at 54, then coiling it around itself as at 56 and finally forming a small coil 58 to embrace part 54 and constitute a pivot between reach 52 and the intermediate reach 60 extending to hook 48. It will be obvious that as far as the broader aspects of the invention are concerned, the resilience required may be provided by a helical coil located either sideV of pivot 42, or by employing wire of proper diameter, suitable action can be obtained without any coil at all. Any element fastened to or moving with link 44 could be an effective substitute for the wire. n

Without 'further elaboration, the foregoing will so fully explain the gist of the invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service. It will, for instance, be obvious that by omitting the arm 62, and leaving lock nut 34 a little loose, the ear piece could be swung around the horizontal axis of bolt 28 instead of around the vertical axis of standard 26. This and many other modifications and alterations may be made without eliminating certain features which may properly be said to constitute the. essential items of novelty involved, which items are intended to be defined and secured to us by the following claims. i

We claimz- Y 1. In combination, a telephone instrument comprising' a transmitter and a receiver, an extensible support for carrying the instrument substantially horizontally to and from the user, circuit control means, and means for automatically operating said control means to adjust the circuits for talking lfor holding said receiver spacedfrom said transmitter.

3. In combination, a telephone instrument comprisingY a transmitter and a'receiver, an extensible supportfor carrying the instrument substantially horizontally to and from the user, circuit control means, means for automatically operating said control means to adjust the circuits for talking upon pulling the instrument toward the user, and to adjust the circuits for ringing upon pushing the instrument away from the user, said instrument including a support for holding said receiver spaced from said transmit-ter, said support vbeing movable, and connections for retracting said support when the entire instrument is pushed away from the user.l

4. The combination with a lazy tongs support and a telephone instrument mounted on the extensible end thereof, said instrument including a receiver and a transmitter, of circuit controlling means" movable into two positions, i. e. a first talking position and a second ringing position, and a connection for automatically shifting said circuit controlling' means from the second to the first position upon extension of said support, and vice versa. y

5. In combination, a telephone desk stand including a transmitter, a receiver and a switch hook, a horizontally extensible support for said desk stand, and means controlled by the movement of said extensible support for raising and lowering the switch hook independently of said receiver.

In witness whereof, we hereunto subscribe our names this 13th day of August, 1923.
