To all whom f'itmaj concern. I V Be it known that I, CHARLES It. Scenes, of Syracuse, in the county of Onondaga, in

the State of New York, have invented new.

and useful Improvements in Telephone- Stands, of which the following, taken in con neotion-With the accompanying drawings, is a fulh elear, and exact description.

- This invention relates to certain improvements in telephones and refers more p articularlyto receiver supporting attachments for des telephones whereby the ordinary receiver may be supported 1n operative pos1 tion ready-for use in connection, with the 'transnnttenleavlng the hands free for use.

i The main object is to provide means for supporting the receiver at the proper distance from the transmitter and to enable 'suoh receiver relatively to the transmitter to conform to the relative position of the mouth ear of the user.

: 'One of the specific objects is to provide means for locking the usual switch arm which ordinarily carries the receiver in one of its adjusted positions.

Another specific object is to provide spring clamping jaws for the receiver with means for tightening the jaws thereon.

. Other objects and uses will be brought out in the following description.

- In the drawingsFigure 1 is a side clevation of an ordinary desk telcphoneshowing my receiver supporting attachment as operatively mounted upon the transmitter sup porting standard. I Fig. 2 is a front elevation of the device seen in Fig. 1' showing portions of the transmitter and receiver as broken away. Fig. 3 is an enlarged elevation partly in section of the spring clamping jaws for the receiver showing the tightening nut 111 sectron. Figs. 4, 5 and 6 are sectional views taken respectively on linos44, 55, Fig. 2

and 6 6, Fig. 1.

In orderto demonstrate the practicability of my invention, I have shown an ordinary weight of the receiver when supported upon the switch arm -5 operating to hold it in one of its adjusted positions to cut out the receiver circuit but when it is desired to use the instrument it is necessary to take the re-- ceiver in one hand and frequently becomes necessary to hold the-transmitter supporting standard in the other hand while in my presrnt invention I have sought to provide an attachment whereby the receiver of the ordinary desk or wall telephone may be permanently positioned for use in connection with the receiver without necessitating handling the same thereby leaving both hands free for any otherwork which the op erator may wish to perform. In the use of this attachment which I will presently de- I scribe, Iprovide means consisting in this instance of a lock lever Zadapted to be manipulated by hand for locking the switch. arm v5-- in one of its adjusted positions as for instsnee in, cutting out the receiver, said lock lever bcing pivoted at 8-- to a suitable support 9 which is clamped upon the stanlard l directly above the switch arm 5, the lower end of the lock lever being movable into and out of contact with the upper end of said switch arm so that the latter may be locked in its down position by moving the switch in one direction.

and may be released and allowed to closethe circuit through the receiver by being spring pressed upwardly in the usual manner when the locking lever is moved in the opposite direction or out of engagement therewith. The support -9 preferably consists of a split ring or strip clamped around and against.

the periphery of the sttnlard -.1- and having its ends offset laterally for receiving between them the lock lever 7- which is held by the pivotal bolt 8 as best seen in Fig. 4. This clamp is preferably secured to the upper end of the standard and upon the lower end of said. standard is secured a similar clamp having its ends offset laterally atone side of the standard and adapted seen in l igf5. The intermediate portions of both of these clamps '9 and :1() are deflected laterally some distance to one side of the standard -1 and are returned upon this forming eyes -12 in which is clamped an upright arm ,13-, the opposite sides of the eyes being drawn together by suitable clamping bolts -llto hold the rod or to be tightened upon said standard as best may be adjusted circumferentially around desired position.

the standard to bring the rod 13 to any A horizontal receiver supporting arm 15 is secured bysuitable fastening; means as a bolt --16 to the upper end of the rod -13- and is provided with a lengthwise slot 17 receiving the bolt 16' and permitting lengthwise or horizontal adjust-- mentof the receiver and supporting; arm --l, the bolt -16- also serving as a pivot upon which the arm -l5- inay be rocked vertically. This receiver supprn-ting armis located some distance above the transmitter 3- and extends from a point at the rear some distance in [rent and to one side of said transmitter and its tree end is provided with opposite spring jaws --lS- having separately movable clamping plates l9- for engagement with diametrically opposite sides of the shank ol the receiver **6 as best shown in Figs. 1 and 2, said clamping, ]')lates being of greater transverse width than the width of the spring jaws 18- upon which they are mounted by pivotal bolts 20 i The "ing jaws *iS- are formed by splitting the free end of the arm l5 inwardly and then bending the free ends of the jaws to the desired curvature for tilting upon and around the shank or base of the receiver -6-. The outer faces of the bases of the jaws 18 are provided with tapering threaded portions --21 which are engaged by a hand nut --22 which when rotated in one direction operates to tighten the jaws lS- upon the receiver to hold the latter iirmly'in its operative position and by ro'tati ing it in the opposite direction permits the jaws to release the receiver from the grasp of the jaws.

The clamping members 0 and upright rod 13- and receiver supporting arm constitute an htitachment which may be applied to any ordinary desk telephone and permits the receiver to be readily attached to the jaws 18 Withoutin any way reconstructing or modifying the transators.

mitter supportoi other parts of the ordinary desk telephone. ment the receiver may be permanently su ported in operative position relative to t e transmitter ready for use at any time without applying the hands thereto, although the receiver and supporting arm may be adjusted longitudinally or rocked vertically to bring the earpiece of the receiver into proper relation to the mouth piece of the transmits ter to conform to the diil'erent relative posi tions of the mouth and ear of different oper- What I claim is: 1. in combination with a telephone transnutter and a support therelor, of an upper Inithe use of this attach-.

and a lower clamp secured to the support, an i adjustable and vertically disposed supporting arm suspended by said clamps, a switch arm on the support, a locking member for said. switch arm, said locking member carried by the upper of said clamps and arranged at right angles with respect to said siipporting arm, a receiver supporting arm a'djustably connected to said vertical arm, said receiver supporting arm having one end formed with a pair of spring jaws, clamping plates pivoted to said jaws and adapted to engage a receiver, and means cairicd by the receiver arm and adapted to engage said jaws for clamping the receiver to said dates.

2. In combination with a te ephone transmitter and a support therefor, of an upper and a lower clamp secured to the support, an

adjustable and vertically disposed support arm having one end formed with a pair 0 spring jaws, clamping plates pivoted to said jaws and adapted to engage a receiver, and means carried by the receiver arm and adapted to engage said jaws for clamping the receiver to said plates. ln witness whereof I have hereunto set my hand this 18 day of March 1908.
