15 Claims. (Cl. 179-150) Matter enclosed in heavy brackets appears in the original patent but forms no part of this reissue specification; matter printed in italics indicates the additions made by reissue.

The invention relates to an accessory for use with a telephone, and more particularly to such an accessory adapted for holding the combined transmitter and receiver in a convenient position for use, thus leaving both hands of the user free for other purposes.

One of the objects of the invention is to provide an accessory of the class described, having the combined transmitter and receiver in any a one of a variety of positions.

Additional objects of the invention will be apparent from the drawings and from the following specification and claims.

In the drawings I have shown in detail a preferred embodiment of the invention, but it will be understood that various changes may be made from the construction shown, and that the drawings are not to be construed as defining or limiting the scope of the invention, the claims forming a part of this specification being relied upon for that purpose.

Referring to the drawings, Ill represents a supporting plate or platform which carries the other parts of the accessory and which also supports the base of the telephone with which the accessory is to be used. The platform is shown as being rectangular in shape but the shape of the platform may be widely varied. The platform may be formed of any suitable material such as laminated woodror molded plastic. The platform may be provided with felt pads l2, l2 in order to avoid scratching or marring the desk on which the platform may be placed. A stud I3 may be provided at the front right corner of the platform which may be manually engaged for moving the entire platform.

Carried by the platform is a vertical post l4 which serves to support various other parts as hereinafter explained in detail. The post I4 is preferably detachably connected with the platform It and as shown in Fig. 4 the platform is provided with a vertical stud I6 which is held in place by a screw it. The stud it enters and fits a central vertical opening in the bottom portion of the post. It will be seen that the post can be readily engaged with or disengaged from the stud. Preferably the stud I6 is provided with a flange 20 and the post I4 is provided with a mating flange 22. A pin 24 projects upward from the flange 20 and through an aperture in the flange 22. The pin 24 serves to locate the post in a predetermined position with respect to the stud l5 and with respect to the platform It.

Supported on the post [4 by various parts to be described in detail is a holder 26 for the combined transmitter and receiver 28 of the telephone. The base 30 of the telephone is supported on the platform It adjacent the post M. For convenience of illustration the telephone base 30 is shown in Figs. 1, 2 and G as positioned with its edges parallel with the edges of the platform, but in use it is ordinarily more convenient for the base to be diagonally positioned. Preferably the platform It has lines 32 described thereon for indicating the most convenient location of the base with respect to the platform and for indicating the proper spacing of the base from the post 14. Normally the transmitter and receiver 28 is supported by the holder 25 so long as the accessory is in place and it is not returned to engagement with the base 30.

The base 30 has the usual vertically movable button 34 which is held in its lower open-circuit position by the combined transmitter and receiver when the latter is in its originally intended position on the base, the said button being biased to its upper closed-circuit position. However, when the present accessory is in place the transmitter and receiver is supportedon the holder I the post l4 and this mechanism will now be described.

Vertically movable on the post I4 is a slide which is preferably in the form of a sleeve surrounding and fitting the post. Carried by thr [side] slide or sleeve 35 is a horizontally extending arm 38 which extends over the button 34 as shown in Figs. 1, 2 and 6, Preferably the sleeve 36 is guided for vertical movement on the post l4, relative rotative movement being prevented. As shown, the sleeve 35 is provided with a vertical interior spline 4t and the post carries a pin 42 which enters the said spline. Thus the sleeve 36 is free for vertical movement, but relative rotative movement is prevented.

Preferably the arm 38 is rotatively connected with the sleeve 36, this being desirable in order that the telephone base may be placed in different positions on the platform [0. As shown, the main portion of the arm 38 is formed integrally with a centrally ap'ertured hub 44. A portion of the aperture in the hub fits the post 14 and another portion fits a reduced portion of the sleeve 36.

For vertically moving the sleeve 36 and the arm 33 there is provided at least one manually movable eccentric and preferably there are two such eccentrics. As shown, the post [4 is flattened at opposite sides and a rotatable shaft 46 extends through a horizontal bearing aperture in the post. Secured to the shaft 46 are two similar eccentrics 43, @8 which engage the opposite flat faces of the post. Connected with the shaft 46 and the eccentrics 48, i8 is a manually operable lever 50 for Ill) turningthe said shaft and eccentrics. When the lever 50 is in the upper position, as shown in Figs. 1, 6 and 7 the eccentrics are in the positions to permit the sleeve 36 and the arm 38 to move to their lowermost positions. is moved to its lowermost position, as shown in Fig. 2, the eccentrics are moved to the positions shown in Fig. '2 and the sleeve 36 and the arm 38 are moved to their uppermost positions. Inasmuch as there are twoeccentric's, pressure is applied to the sleeve 36 at both sides of the post. A pin 52 on the post 14 limits the movement of the lever 50, so that thesleeve 36 and the arm 38 are either in their lowermost positions or in their uppermost positions. Preferably the lever 50 has notches asshown to receive the pin 52.

Aspring is preferably provided for biasing the sleeve 38 and the arm 38 in the downward direction and as shown there is a coil spring *54 which surrounds the upper portion of the post l4 and which is within an upward extension of the hub- 44 on the arm 38. The upper end of the spring 54 abuts against a nut 55 having threaded engagement with the upper end of the post I4.

As has been stated, the arm 38 engages the button 34 on the'base of the telephone. When the 'lever 50 is moved to the position shown in Figs. 1, Band -7, the-arm '38 is moved downward by gravity and by the spring 54 'so as to depress the button 34 to its lower open-circuit position. When the lever"'50is moved"to the position shown in Fig. 2, the sleeve '36 and the arm 38 are moved upward thus permitting the button 34 to assume When the lever 55 4 its upper closed-circuit position. Thus the user of the accessory can close or open the telephone circuit at will by merely moving the lever 53.

The base of the telephone has the usual upward projections 58, 58 at opposite sides of the button 34 and preferably the arm 38 is provided with a pair of aligned rollers positioned respectively for engagement with the said projections 58, 58 atthe sides thereof adjacent the post 14. As shown, there are two pairs of rollers which are so positioned that the rollers of the said pairs are at opposite sides of the said projections 58, 58. The rollers of one pair are indicated at 60, 80 and the rollers of the other pair are indicated at 62, 62, the rollers 65, 60 being at opposite sides of the front projection 58 and the rollers 62, 62 being at opposite sides of the rear projection 58. The rollers are preferably formed at least in part of rubber or equivalent material.

Preferably each two rollers 60 and 62 are retatably mounted on a pin 64 as shown in Figs. 7 and 8, the rollers being held in place by means of screws 65, B6. The main body of the arm 38 is provided with transverse recesses 58, 6B.

The arm 38 includes a separate bottom plate 10 which is held in place by screws and which closes the bottoms of the recesses 68, 68. Vertical pivot pins 12 extend through thepins 64, B4 and through the main body of the arm 38 and through the bottom plate 10 thereof. Thus the pins 64, 64 which carry the rollers are free for slight :oscillatory movement.

The telephone base 30 is accurately positioned on the platform 10 so that the projections 58, 55 thereof are between the pairs of rollers 50, 60 and 62, '62. The rollers constitute anti-friction means which permit the arm 38 to vmove freely upward or downward with respect to the base and inasmuch as the said rollers are formed at least in part of rubber or equivalent material, there is no possibility of scratching or marring the said projections on the base. Inasmuch as the rollers can oscillate they can adjust themselves to minor inaccuracies in the location of thebase 35 with respect to the post I'4.

The telephone base shown in Fig. l is that of a standard telephone. Certain other telephones, as for instance those for inter-office use, have the button 34 at a slightly higher elevation. To accommodate such higher elevation of the button 34 an alternative stud 74 may be provided, as shown in Fig. 5, this stud being provided with a flange '76 which is somewhat thicker than the flange 26 shown in Figs. 1, 4, 6 and '7. The flange 16 of greater thickness :holds the entire accessory at 'a slightly higher elevation so as to accommodate the higher :elevation of the button 34 The upper portion of the post 14 hasa central cylindrical aperture therein and a vertical rod 18 accurately fits this aperture, being rotatable therein. The lower'end'of the rod 78 is preferably reduced in "diameter, and the lower end of the aper'ture in the post F4 'has'a corresponding reduced diameter. There is thus provided a "shoulder 15 which con'stitutesa bearing for supporting the red when it 'is in its lowermost position as shown.

A laterally extending arm 88 '"is provided which is connected at one end with the upper end of the rod 18. The arm 88 is pivotally movable relatively to the rod -'to positions at vertically different angles. As shown a two-part socket clamp is connected with the upper end of the rod I8, this clamp having left and right parts 80 and 82 formed of sheet metal. The left part 80 of the clamp has an offset 84 to which is secured a nut86. As clearly shown in Fig. 7, the upper end of the rod 18 is reduced in diameter and is threaded for engagement with the nut 86. The extreme upper end portion of the rod I8 is peened or riveted to hold the rod 18 and the nut 86 in permanent engagement.

The laterally extending arm 88 is shown as having a ball-like enlargement 90 which is clamped between the two parts 80 and 82 of the clamp. The projecting end of the arm 88 carries the holder 26 in a manner to be described. A bolt 92 extends through apertures in the two parts 80 and 82 of the clamp and is engaged by a nut 94. By turning the nut 94 the bolt acts to draw the two parts 80 and 82 of the clamp toward each other so as to clamp between them the ball-like enlargement 90 of the arm 88.

A member is provided which is carried by the the said rod I8 and which has therein a plurality of notches of different depths for receiving the arm 88 and for supporting it in any one of a plurality of positions at vertically difierent angles. As shown, the said ball-like enlargement 90 of the arm is generally pear-shaped and the right part 82 of the clamp constitutes the said notched member, and is provided with a plurality of notches 96, 66 into which the right end of the ball-like enlargement 90 can fit. As shown, there are three notches which are of different depths. the ball-like enlargement 90 is seated in one or another of the notches 66, 90 the arm 88 can be held in three angularly different positions. This makes it possible for the holder 26 and the combined transmitter and receiver 28 to be held not only in different elevations but at different angular positions'to suit the convenience of the user.

Under some circumstances it may be desirable to provide for angular positions of the arm 88 additional to those which are provided by the three notches 96, 86. When this is desirable the ball-like enlargement 90 of the arm 88 may be provided with annular grooves 68, 98 and the edges of the clamp part 80 may be provided with lips I adapted to be seated in one or another of the grooves 68, 98'by means of the said grooves 98 and the said lips I60, the ball-dike enlargement 90 may be gripped and held in positions other than the positions attained by the engagement of the said ball-like enlargement with the bottoms of the notches 96, 68.

The holder 26 is preferably so connected with the arm 88 that it may be rotatably adjusted with respect thereto. As shown there is provided a disc I02 having a hollow hub I04 which is interiorly threaded for engagement with a threaded end portion of the arm 88. A second disc I06 is provided which normally has face to face engagement with the disc I02. The before-mentioned holder includes a sheet metal plate I08 and this plate is connected by means of rivets IIO with a flange II2 formed integrally with the disc I06. The disc I06 is provided with an. integral stud II4 which extends through an aperture in the disc I02 and into the hollow hub I04 thereof. A coil compression spring H6 is located within the hub I04 and surrounds the stud I I4. A screw I I8 has threaded engagement with By placing the arm 88 so that p the stud H4 and the head of the screw serves as an abutment-for the spring H6. It will be seen that the spring II6 normally holds the disc I06 in engagement with the disc I02, but permits it 6 to be slightly separated therefrom when desired. After the parts have been assembled as shown in Fig. 12 a pin I20 may be inserted through the hub I04 and through the threaded end of the arm '88 to permanently lock the parts in assembled relationship.

The discs I02 and I 06 are provided with means which enables them'to interengage with each other so that the disc I06 may be releasably held in a variety of positions of rotative adjustment with respect to the disc I02. As shown in Fig. 13, the disc I02 has an annular series of holes I 22, I22 therein and the disc I06 carries a pin I24 adapted to enter any one of the holes I22, I22. It will be seen that the angular position of the holder 26 with respect to the arm 88 can be changed by moving the holder toward the right in opposition to the spring I I6, thus. withdrawing the pin I24 from the hole I22 in the disc I02. Then the holder can be rotated with respect to the arm 88 and released, the pin I24 entering another hole I22 in the disc I02. Thus the holder is normally held against relative rotation, but can be angularly adjusted as desired.

The holder 26 includes not only the beforementioned plate I08 but also two clips I26, I26 which are adapted to receive and hold the combined transmitter and receiver 28. Clips I26, I26 may be varied as to details but I prefer to provide clips as shown in detail in Fig. 14. As shown, each clip comprises a generally U-shaped metallic spring I28 secured to the plate I08 by means of a rivet I30. Each clip also includes a generally U-shaped body I32 of yieldable resilient material such as rubber, the body I32 being within the confines of the spring I28. The interior of the U-shaped body I32 is shaped to substantially fit the corresponding portion of the combined transmitter and receiver. When the transmitter and receiver is to be put in place on the holder it is pushed toward the plate I08, the clips spreading s'ui'ficiently .to permit the said transmitter and receiver to enter the interior'opening in the base I32 of rubber or equivalent material. Thus the transmitter and receiver is firmly held in place and is engaged only by the bodies of rubber or equivalent material, thus avoiding any possibility of scratching or marring the said transmitter and receiver.

As has been stated, the arm 88 may be angularly adjusted vertically, thus changing the height of the holder 26 and of the transmitter and receiver 28. However, the adjustment of the arm 88 is depended upon primarily for changing the angle of the transmitter and receiver rather than for changin the elevation thereof. The elevation of the transmitter and receiver may be changed by vertically moving the rod 78 with respect to the post I4. The rod I8 has two or more annular grooves I34, I34 therein and the rod 78 can be raised to locate any one of the said grooves I34, I34 just above the top of the nut 56. Withthe rod I0 so raised, a stop I 36, as shown in detail in Figs. 9 and 10, is engaged with the said rod at the last said groove thereof. As shown, the stop I36 comprises a lower plate I38 having a notch therein, and the notched portion of the said plate I38 is adapted to enter the annular groove in the rod 18, the said plate I38 resting on the nut 56 as shown in Fig. 9. The stop I36 also includes a spring I40 which embraces the rod 18 and is shaped to engage the rod to resiliently hold the stop in place. The sto may also comprise a second plate I42 at the top for covering the spring I40.

Fig. 7 shows the rod I8 in its lowermost position, it bein supported on the shoulder at I9. The rod can be raised to position either of the grooves I34, Iii-l adjacent the top of the nut 55', and the stop I36 can be snapped in place. Fig. 2

shows the rod 78 raised and'shows the stop I36 engaged with the rod at the lower groove 34 therein. The rod I8 can be held at any one of three elevations, and the number of positions may be increased by increasing the number of annular grooves I34, I34.

Preferably the rod I8 is provided with an additional annular groove near the top thereof with which the stop I35 can be engaged when the rod is in its lowermost position as shown in Fig. 7. When the stop is in the position shown in Fig. 7 it has no function, but it is retained in place so that it will not be lost.

The usual cord I44, connecting the transmitter and receiver with the base, may be held by a hook I46 carried by the arm 88. Thus the cord is maintained in a convenient elevated position.

From the foregoing description it will be apparent that the transmitter and receiver 28 may be held in any position that is most convenient for the user. It may be adjusted angularly in one direction by changin the position of the arm 88 with respect to the socket clamp and it may be angularly adjusted in another direction by changing the positionof the disc I 05 with respect to the disc N32. The elevation may be changed by raising the rod I8 and putting the stop I in place at one of the grooves I34, I34. The transmitter and receiver can at all times be freely rotated about the axis of the rod I8 and the post I4;

With the transmitter and receiver adjusted to the most convenient position, the user has his hands free at all times for handling papers and for making notes and the like. When the telephone is not in use the lever 58 is in its upper position as shown in Fig. 1. Whenever the telephone is to be used the user merely moves the lever 5% to its lower position as shown in Fig. 2,

thus opening the telephone circuit so that the desired number can be dialed in the usual manner. Upon completion of use the lever 53 is restored to the position shown in Fig. 1.
