P. SWAINE TELEPHONE SET Filed dgt. so, 1934 Patented Nov. 12, 1935 UNITED STATES PATENT ,oFFicE TELEPHONE SET Percy Swaine, carborough, England Application October 30, 1934, Serial No. 750,636

' In Great Britain September 26, 1933 p 7 Claims. The present invention relates to new and useful improvements in telephone sets or to attach-:. ments or accessories therefor of the type in 15 ceiver to an operative position for the transmission of a message.

A further object of the invention is to provide a device of the above character wherein there is provided a movable platform and means con- 20 necting said platform with the receiver and the hook switch whereby upon the movement of said platform, the required electric circuit is established and the receiver is moved to an operative position for the transmission of a message. 25 The above and other objects of the; invention will in part be obvious and will be hereinafter more fullyvpointed out.

In the drawing:

Fig. 1 is a perspective view of a telephone set I 30 of the type embodying a receiver and a mouth,- piece as separate elements and showing the construction of the present invention applied there- Fig. 2 is a side elevation. of a telephone set em- 35 bodying a receiver and a mouthpiece as a single unit and showing the construction of the present invention as applied. thereto.

Figs. 3, 4 and 5 are detailed views showing modifications of the operating platform and the 40 manner in which they are displaceable.

Referring more in detail to the accompanying drawing and particularly to Fig. 1, the mouthpiece III is connected to the usual standard II which is mounted on a base plate I2. Extending 45 from the standard II is the usual hook switch I 3 which establishes the necessary electric circuit. A platform It has side arms Ha which are pivotally mounted on the base plate I2 as at iii. A bracket member I6 is suitably secured to I50 the standard II and has an outwardly projecting portion I60. to which ispivotally mounted at ll a rocker a'rm I8. The arms Illa of the platform ll are suitably connected to one end of the rocker arm I8. In this particular instance, the arms 65 I la are connected by a forked link I9 which in turn is connected to a second link 20 pivotally connected as at 2I to the rocker arm I8. The receiver 22 is carried by a spring clip 23 which is adjustably mounted on a post 24. The post 24 fits within asleeve 25 and is adjustable verti- 5 cally therein and is held in position by a knurled nut 26. The sleeve 25 is pivotally mounted for swinging movement on an arm 21 and is held in position by a wing nut 28. The arm 21 is pivotally mounted for. horizontal turning movement on the rocker arm Hi. It will thus be seen that K the receiver 22 may be adjusted relative to the rocker arm l8 and is capable of a universal movement relative thereto.

As shown in Fig. 1, the rocker arm I8 is disposed over the hook I3 so that in this position the hook switch I3 is depressed and the circuit is closed. A spring 29 serves to normally hold the platform It in a raised position although the weight of the receiver on the rocker arm I8 may serve this purpose. It will be noted that when the platform I4 is depressed, the connecting links I9 and 20 will move downwardly thus'causing the rockerarm ill to move in a clockwise direction about its pivot I1 so that the hook switch will be permitted to ascend and thus establish the required electric circuit and at the same time the receiver 22 will be moved in a clockwise direction to an operative position relative to the mouthpiece I I] so that the operator does nct need 30 to hold the receiver at any time after it has once been adjusted.

-A pivoted catch 30 on the base l2 may be employed for holding the platform It in its depressed position with the telephone set inan operative position with the circuit established. If it is desired to permit an operator at an exchange or some other remote point to control the set, an electromagnet 3| is provided which, when energized, exerts a pull on the catch Slim 9. direction toward the platform I4 so as to hold the same in its depressed position. Should the circuit be broken by the operator, the magnet will be de-energized, and the spring catch 30 will move out of contact with the platform so as to release it.

A sign 32 is mounted on the base I2 and is normally disposed beneath the platform I4, but when the platform is depressed, the sign is disposed above the same so as to indicate to the observer that the set is in a position consistent with use. A writing pad or the like, Mb, may be mounted on the platform I4.

Referring to Fig. 2, there is shown a telephone set of the type wherein the mouthpiece and rcceiver are a single unit. In this case, the platform I is pivoted to the base l2 in a manner similar to that shown in Fig. 1'. A bracket lGa f has pivotally mounted thereon a rocker arm I811 5 which is connected by a link 20a to the platform II. The rocker arm Ila has mounted thereon for adjustment a sleeve 25a. in which is mounted a post 24a which may be adjusted vertically and held by a knurled nut 26a. The post 24a carries a spring clip 23a in which the mouthpiece Ma of the telephone set is mounted. The rocker arm Ila extends over the hook switch [311 in a manner similar to that shown in Fig. 1. When the parts are inthe position shown in Fig. 2, the

- hook switch I 3a is depressed. When the platform I 4 is moved downwardly, the connecting link a will cause the rocker arm lfla to move in clockwise direction, thus releasing the hook switch Ba and moving the receiver or ear piece 22a to an oper- 20 ative position.

In Fig. 3, the depression of the platform ll may be through the medium of a foot rest (not shown) which is connected thereto by a link 33. This link 33 may be formed as an extension of the link 19 or the link 20a.

' In Fig. 4, the platform I 4 is pivotally connected to a link 34 which is pivoted at one end to the base l2 and intermediate its ends to the link I! or 20a. In this form, the depression of the platform I 4 causes the same to slide longitudinally of the base plate It.

In Fig. 5, the platform I 4 is shown mounted on a pair of links 35, one of which may be connected to the link I! or Me. In this form, the

5 platform I! remains parallel to the base l2 while it is being depressed.

It will be readily understood from the foregoing description, that the present invention provides an improved telephone set or an attachmenttherefor which operates to establish the required circuit and at thesame time to move the receiver into an. operative position so that the operator need not hold the receiver at any time, thus allowing free use of the hands for taking notes or the like.

' I claim:
