Be it known that I, JOSEPH SILYERMAN, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Im rovements in Telephone Attachments of whlch the following is a specification.

'My invention relates to a telephone attachment, and especially to a hook-o crating device for use in conjunction wit means for holding the receiver in suitable relation to the mouth iece. Its ob'ect is to provide a device ap icable for eit er wall-tele hones or for deslE and hand teleph0nes,whic shall be simple practical, not too ex ensive, and whichwill permit of a quick an satisfactory ad'ustment of the receiver-holder to either si e of the mouth iece and allow the operator to hear throug either ear, and by which device both hands will be left free.

The invention consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawin 's, in whichigure 1 is a side elevation of my invention, showing its application to a hand-telephone stand, the receiver-holder being omitted. Fig. 2 is a front elevation of the same. Fig. 3 is a plan view of same.

A re resents a base or stand provided with suitab e means, as the screw-clamps 2, to receive and hold a desk or hand telephone 3 of ordinary construction. The base is of sufficient size and weight to holdthe various parts'of the device without tipping over, but

is preferablycapable of easily being moved by hand to any portion of a desk or table.

. Extending upward from this base is a rod or standard 4, carrying the adjustable sliding arm 5, which is arranged relative to the telephone-hook 6, by which the circuit is usually made and broken. The arm 5 supports a vertically sliding slotted member 7 ,which rests on a cam-finger 8. The telephone-hook 6 is engaged by the part 7, and a spring 9, connected with the hook, normally holds the hook down to disrupt the-circuit. Pressin down on the cam-finger lifts the hook 7 an the hook closes the circuit and connects the telephone with central station. When the finger is pressed clear down, the stem .of member 7 rideson a fiat part of the eccentric surface of thecam and abuts against a stop ,10,

er is tripped, when the spring 9 will draw the 00k down again. V 1 v I, The holder for the .tel'ephonereceiver is represented-by a lengthwise andsidew ise adas ihihtok will stay up until the cam-fin-' in three parts, the central part beingslotted and angular and having one end extendible by means of the set-screws 14 and guide-pins 14 to lengthen or shorten the carrier, the other end similarly extendible by means of the screws 15 and guideins 15' to'lengthen or shorten the radius of t e are of movement of the carrier about its horizontal pivot 16. The outer end of the arm 11 carries a spring clasp or holder 17, adapted to hold the telephone-receiver in horizontal .position. The pivot 16 is so positioned relative to the telephone on the stand that the arm 11 will have an equal sweep from side to side of the mouthpiece. For this reason the carriage 12 projects out from the rod 4 to bring the pivot 16 into approximately a vertical line with the center of the mouthpiece. When the operator desires to hear with the left ear, as is usual, the arm is thrown to the left of the mouthpiece and the holder 17 and collar 18 adjustedto maintain the receiver in the position best suited to the needsor fancyof the operator. In case he wishes to hear with his right ear the receiver is detached temporarily'from the holder, the arm turned over on the pivot 16 to. the ,ri ht of the mouthpiece, and the holder an collar adjusted so that when the receiver is placed in the holder the receiver will be properly supported on top' of the arm and relative to the mouthpiece.

By a slight change in construction the same invention is applicable to walltelephone.

It is possible that various other modifications in my invention may be made without departing from the principle thereof, and I do not wish to be considered as limiting myself Ito'my specific construction beyond a reasonable interpretation of my claims.

This a plication is a division of my original a p ication, Telephone attachment,

LOO

Having thus described my invention, what I claim, and desire toseoure by Letters Patent is 1 The combination with a telephone of an attachment therefor having means for holding down the hook, said means including an adjustable arm carrying a vertically-reciprocating part to embrace the hook, a spring on said arm operatin on the hook in opposition to its tendency to ift, and means for reciprocating said part in opposition to said spring.

2. The combinatlon with a telephone of means for holding down the hook comprising a vertically-reci rocating rest for the hook, a support for sai rest, and means including a pivoted cam-finger for reciprocating said rest.

3. The combination with a telephone and the hook thereof, of a stand for the telephone, a vertical standard supported on the stand, a part adjustable on said standard,

and means on said part including an oscillating cam for operating the telephone-hook.

4. The combination with a telephone and the hook thereof, of a vertical standard, a part adjustable on said standard, means normally actin to hold the hook down, and means inclu ing a cam-finger to lift the hook.

5. The combination with a telephone-hook, of a spring to hold the hook down and means acting in 0 position to the spring to lift the hook, said ifting means including a pivoted cam member.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOSEPH SILVERMAN.
