ROBERT A. BONIVENTURE, OF NEW YORK, N. Y.

TELEPHONE.

To all whom it may concern:

Be it known that I, ROBERT A. BONIVEN- Tune, a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Telephones, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invent-ion relates to telephones and particularly to what are known as stand, desk or table telephones, and the object thereof is to provide an improved receiver attachment for telephones of this class whereby the necessity of holding the receiver to the ear by hand is avoided and whereby the wires of the receiver circuit are concealed or partially concealed and prevented from becoming twisted, tangled or formed into loops which frequently occurs in telephones of this class as usually constructed, a further object being to provide a receiver attachment of the class specified which is composed of separate mechanical parts, part of which are movable and one of which consists of a rotary and vertically movable arm by which the receiver is supported, all of the parts being connected with a telephone of the class specified without interfering, in any way, with the construction thereof, and with these and other objects in view, the invention consists in a receiver attachment for telephones of the class specified, constructed and operated in the manner hereinafter described.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my invention are designated by suitable reference characters in each of the views, and in which,-

Serial No. 617,591.

and Fig. (3, a section on the liuc (SW6 of Fig. 1 and on an enlarged scale.

In the drawing forming part of this specifieation, I have shown an ordinary stand or desk telephone comprising a standard a, having a base ag'and with the top of which the transmitter o is connected in the usual manner, and the standard a is provided with the usual receiver supporting arm a* pivoted at a5 and having the usual receiver yoke a, and the pivoted end of which is provided with a downwardly directed finger a7 between which and the standard a is placed a spring as, and said pivoted end of the arm a4 is also provided with the usual upwardly directed and curved finger member a which passes into vthe standard a and operates in connection with the circuit making and breaking device b, said standard a being also provided with the usual transmitter circuit wires be, all of these parts being of the usual construction.

In the practice of my invention, I dev tachably connect with the standard a a top arm c and bottom arm c2 and the bottom arm c2 is provided with a head c3 into which is screwed a receiver standard tube (Z which passes through a keeper c4 with which the arm c is provided. Secured in the top of the tube (Z is a tubular plug (Z2 in which is secured a supplemental tube e, and the tubuiar plug [Z2 is provided at the top thereof with a flange or rim (Z3, and inclosing the supplemental tube c is a sleeve f in the lower end of which is secured a tubular plug f2 through which the supplemental tube c loosely passes, and the tubular plug f2 is provided at its lower end with a flange or rim f3 which corresponds with the rim or flange (Z3 of the tubular plug d2, and secured to the flange or rim f3 of the tubular plug f2 is a ring or band y which incloses the flange or rim (Z8 and which is provided with an inwardly directed flange or rim f5, and between the flanges or rims (Z3 and f3 of the tubular plugs d2 and f2 is a ball race f and between the flange or rim (Z3 of the tubular plug d2 and the flange or rim f5 is another' ball race f7. As thus constructed it will be seen that the sleeve f is rotatable on the supplemental tube c which is stationary, and the top of the sleeve f is closed by a plug g having ears g2 between which is pivoted a receiver arm L.

Within the top portion of the sleeve f the CIT supplemental tube e is provided with a spacing collar e2 above which and in the annular space formed by the parts e and f is placed a spiral spring e, one end of which is secured to the tuloe e at et and the other end of which is secured to the sleeve f at e5, and with this construction the sleeve or arm h is normally held in the position shown in Fig. l but when it is desired to use the receiver the said receiver arm is swung forwardlya quarter of a circle or approximately so as indicated in Fig. 4.

The receiver circuit wires z' pass up through the receiver standard formed b y the parts (Z, c and f, and pass out through the aperture g3 in the plug g, and are then passed through the receiver arm 7L, and connected with the receiver h2 in the usual manner, and the receiver h2 is preferably what is known as a watch-case receiver. The receiver arm 7L is provided with a head 72.3 which fits between the ears g2 and the pivotal connection at 7b4 is such that the friction thereof will hold the arm L in any desired position of vertical adjustment but said arm need never be adjusted above the position shown in Fig. l.

Secured to the head ha of the arm h or to said arm adjacent to said head is a downwardly directed finger y' which passes through a corresponding aperture j in the plug g, and the stationary member e is provided in one side of its upper end wit-h a recess js adapted to receive the linger j, and when the arm z, has been rotated into the position shown in Fig. 4 a slight depression of said arm will force the lower endv of the finger into the recess and the arm L will be locked in the position shown in Fig. 4, and the transmitting circuit in the standard a will be closed as hereinafter described.

Mounted on the arm at is a longitudinally ranging bolt 7c which is secured to said arml by a pin 7a2, said bolt being provided, in the construction shown, with base flanges k3 and the outer end of the bolt 7c is provided, in the form of construction shown, with a head kt movable in a spiral slot 725 formed in the sleeve f, and the head ist of the bolt 7c preferably consists of a rotary anti-friction sleeve, and by means of this construction, when the arm 71. is swung into the position shown in Fig. 4, the arm a4 is raised and the circuit through the standard a is closed in the usual manner as will be readily understood.

From the foregoing description it will be seen that my receiver attachment does not in any way change the construction of the telephone as originally made and operated, my improvement consisting of separate parts detachably connected with the standard a and with the original receiver supporting arm a4 and whenever desired, or if desired at any time, my attachment may be. removed and the original telephone used in the usual ianner, all that is necessary being to provide the arm a4 with the usual receiver.

The receiver 7b2, as hereinbefore stated, is what is known as the watch-case receiver and is held in place by a clamping device h5 which engages the body portion thereof and which consists of separate spring jaws connected at one end with a head he having a screw 71.7, and the opposite ends of which are connected by a bolt or similar device 7a2", but my invention is not limited to any particular means for connecting the transmitter /Lg with the arm 7L.

As hereinbefore stated, in order to close the circuit through the standard a, the arm /L must be swung into the position shown in `full lines in Fig. 4, and if it is desired, at

any time, to discontinue the use of the telephone, for any purpose, without breaking the circuit, all that is necessary is to depress the arm 7L when in said position so that the finger j will enter the recess jg as shown in Fig.A 3, and this will lock said arm in the posit-ion shown in full lines in Fig. 4.

Although I have shown and described the preferred form of my improvement, my invention is not limited to the exact construction, combination and arrangement of the parts herein shown and described, and various changes therein and modifications thereof may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new, and desire to secure by Let-ters Patent, is

l. In a telephone, the combination with the standard of the transmitter having the usual pivoted receiver supporting arm and the usual circuit wires which pass therethrough of a receiver supporting attachment comprising a tube adapted to be secured to the standard of the transmitter below said arm and terminating below said arm and provided with an extension of less diameter, and which passes upwardly through the fork of said arm, a rotary sleeve mounted on said extension and also passing through said fork, a tension device for holding said rotary sleeve in a predetermined position, a supplemental receiver arm pivoted to the top of the rotary sleeve and adapted to turn therewith and to swing vertically, means operated by swinging the supplemental receiver arm vertically to lock the rotary sleeve in a predetermined position, and means whereby the rotary movement of said arm and sleeve will operate the first named receiver arm to close the circuit through the standard of the transmitter.
