The support, 1, in this instance is upon a desk or table, for example, a loose and, provided with an integral cylindrical portion, uncontrolled section of the electric connector indicated at 6, within which the reel chamber, which is liable to become entangled with 7, is formed in any desired manner.

portion, 6. The reel chamber is in this instance held in rigid relation with the supporting member, 1, by screws, 12, for example. The base plate, 8, carries a vertically disposed non-rotatable post or shaft, 13, upon which the reel is rotatably mounted. The reel, indicated at 14:, is provided with a centrally located chamber, 15, to receive a coil flat spring, indicated at 16, and the outer annular face of the reel is provided with an annular recess, indicated at 17, of substantially the width vertically of the connecter, and of a depth sufficient to contain a plurality of coils of the connecter. The spring, 16, is connected at one end to the post, 13, and the other end is connected to the reel adjacent to the outer edge of the spring recess, or chamber, 15, and has its coils widely separated. The connecter, indicated at 20, which is of the usual type of telephone cord or cable carrying the necessary wires, two, three or more as may be desired, is given a number of coils around the reel in the annular groove; 17 sufficient to enable the hand piece to be withdrawn from the supporting base, the maximum distance desired, and the connecter is then carried within the spring chamber, 15, through an aperture, indicated at 18, see Fig. 2, and is then carried around the outer face of the spring coils, as indicated in Figs. 2, 3 and 5, and is secured at intervals thereto in any suitable manner, for example, by clips, indicated at 19. The spring is so constructed that when it is wound up to its maximum extent by the reeling off of the exterior coils of the connecter, the coils of the spring will not be brought closer together than would readily accommodate the intervening coils of the con- The connecter is then carried from the innermost coil of the spring over the top of the reel. and preferably above the cover, 10, of the reel case and through an aperture, 21, in the base member, from which it passes through an aperture, indicated at 22, to the interior of the base member, where the wires are connected with the parts within, in the same manner that they would be if the connecter had been led directly from the hand piece. The other end of the connecter, 20, extends through an aperture, 23, at one side of the cylindrical portion, 6, preferably in a tangential manner, as indicated in Fig. 2, with respect to the-reel, said aperture being provided with anti-friction eyelet, 24, or other device, and is connected to the hand piece, at 25, in the usual manner. The connections of the connecter with the telephone apparatus form no part of my invention and will not be specifically described. The connecter, 20, is
own provided with a stop member, indicated at 26, to engage the eyelet, 24, when the connecter is wound up to the desired extent, and it will be seen, by reference to Fig. 1, that the exposed portion of the connecter will extend directly from the base of the supporting member, 1, to the hand piece, without any appreciable slack, and with no uncontrolled slack portions to rest upon the desk or table.
\Vith the apparatus constructed as thus far described, it will be obvious that when the instrument is not in use, the connecter, 20, will be wound up on the reel within the casing, constituting the base of the instrument (or a separate casing connected therewith). When the operator removes the hand piece, 3, from the yoke, 2, to use the telephone, releasing the spring actuated switch plunger, indicated at 2, he can, by simply placing the hand piece in proper position with respect to his head, draw out the connecter, 20, to the necessary extent against the tension of the spring, which will be correspondingly wound up, but will not be sufliciently compressed to bring its coils into contact with the portions of the connecter applied thereto. As the hand piece is moved toward the yoke, 2, to replace it thereon, the connecter, 20, will be rewound on the reel, so that it will not at any time rest upon the supporting desk or table. In some instances it maybe desirable to hold the reel when the connecter has been drawn out to the desired extent, so as to relieve the user of the retracting pull of the spring, and in Figs. 2, 3 and 4, I have shown means for accomplishing this result. This includes a locking pawl and interengaging parts, the one connected with the casing, and the other with the reel, the coacting parts being so constructed that they can be disengaged by a movement of the reel in either direction. For example, in Figs. 2, 3 and 4, I have shown the reel provided with a circular series of locking recesses, indicated at 27, for engaging a vertically movable pivoted gravity pawl, 28, secured to the reel casing or other stationary part of the apparatus. As indicated in Fig. 4, the pawl is provided with oppositely disposed cam portions, 28*, for engaging similar cam portions, 27*, at opposite ends of the locking recesses, 27, the parts being so constructed that as the pawl is pulled out and the recesses, 27, are passed rapidly by the pawl, 28, it will have no effect to arrest the movementof the reel, but by stopping the reel and permitting the pawl to slowly engage one of the recesses, the reel will be held against the retracting force of the spring, but the pawl can be instantly disengaged by pulling the cord a little further, so as to bring the coacting cam faces of the reel and pawl into engagement, and by allowing the connecter to be wound up on the reel, the recesses, 27, will again pass the pawl so rapidly as to cause the coacting cam faces to keep it out of locking engagement with the recesses. I do not limit myself to this specific means for locking the reel in adjusted positions as the same result may be accomplished by other means within the scope of my present invention.
In Figs. 6 and 7 I have shown a modification of my invention, in which figures the corresponding parts are given the same reference characters with the addition of 100 to avoid repetition. I11 these figures, the connecter, 120, is given a certain number of turns upon the reel, 114, within the peripheral groove, 117, thereof, and is then carried upon the upper side of the reel, as indicated at 120, and given a sufiicient number of coils around the stationary stem, 113, to provide a slack portion whichwill uncoil and coil with the corresponding uncoiling and coiling of the portions of the connecter in the peripheral groove, 117. It will be understood that the slack coils, which are indicated at 120*, will be of much smaller diameter than the coils, indicated at 120, in the peripheral groove, 117, and sufficient room will be provided within the casing above the reel to permit the coils, 120", to expand and contract without at any time placing any injurious strain on the slack portions of the connecter, 120. By this means the connecter may be carried from the hand piece to the reel and from the reel to the telephone connections within the base of the instrument without the use of any sliding connections, as in the form of my invention illustrated in the preceding figures. In this construction the rewinding spring, indicated at 116, may be of any desired form, and is preferably contained within the chamber, 115, formed in the central portion of the reel surrounding the stem, 113.
It will be understood that the reel casing may be formed separately from the base of the telephone stand with which it is used and secured thereto, as previously described, and also that it may be applied to the supporting stand of the desk type of telephone, in which the transmitter is permanently connected with the stand, and the receiver only is removable therefrom. connecter extending from the supporting base to the receiver, or the connecter extending from the supporting base to the telephone box or other stationary part, may be wound upon the reel. In illustration of the fore going I have shown in Fig. 8, for example, my improved reel contained in a separate casing, indicated at 206, and secured by clips, 206, to the base, 201, of a telephone instrument. In this instance the connecter, indicated at 220, which is wound up on the peripheral portions of the reel, is the connecter extending from the telephone base, 201, supporting a telephone transmitter, 204, to the telephone box, or other fixed part, 230, representing in this instance the connecter which extends to the receiving instrument, 205, supported upon a yoke, 202, connected with the upper part of the base, 201, in the usual manner. It will be understood that the reel car- In this case either the ried within the casing, 206, will be constructed without interruption and without the use of any sliding contacts.
In Figs. 9 and 10 I have shown a slightly modified construction for arresting the reel when the cord, or connecter, is in the coiled or normal position, and also when it has been drawn out to a predetermined extent so as to prevent the connecter from being sub ected to undesirable strain. In these figures the parts corresponding with those shown in Figs. 1 to 5 have been given the same'reference numerals with the addition of 300, to avoid repetition. In these figures I have shown the reel provided, preferably on the under side, for example, with'a spiral groove, 330, adapted to be engaged by a movable pawl, indicated at 331, pressed upwardly into the groove, by a spring, 334, and being connected with the bottom plate, 308,.of the reel casing in such manner as to permit it to follow the convolutions of the groove. The groove, 330, is of such length as to permit the necessary rotary movement of the reel to unwind a predetermined length of'the connecter, 320, and the pawl and groove are so constructed that the reel will be arrested when the connecter is in the coiled or normal position, and also when the connecter has been drawn out to the predetermined extent. I prefer to form the pawl in substantially the same manner as indicated in Fig. 1, with the releasing cams, indicated at 331, and to provide a locking recess, 332, at the end of the groove engaged by the pawl when the con necter has been drawn out to the desired extent, which recess is also provided with the coacting cam faces 332, similar to the construction illustrated in Fig. 4. The opposite end of the groove, 330, may be provided with a similar recess, indicated at 333, also, but this is not necessary as it may terminate simply in an abutting shoulder or end wall of any desired character, which will enable the pawl to stop the movement of the reel under the influence of its spring. lVith this arrangement the reel will be arrested in its normal position without any strain on the connecter, a sufiicien't length of the connecter being provided to simply enable the hand piece to be placed on the supporting yoke and the reel will also be arrested and preferably locked when the hand piece has been removed and the connecter has been drawn out to the predetermined extent for use. This construction will dispense with the employment of a stop, such as is indicated at 26 in Fig. 1, on the connecter, and will also dispense, if desired, with the use of the circular series of locking apertures, such as are indicated at 27 in Fig. 2 and 127 in Fig. 6, and the coacting locking pawl. It is obvious, however, that these locking recesses and the coacting pawl therefor could also be employed, if it were set, comprising a supporting member and a hand piece provided with transmitter and receiver, of a connecter reel connected with the base of said supporting member, a rewinding spring therefor, and a connecter connected with said hand piece, and having portions engaging said reel, adapted to be withdrawn therefrom when the hand piece is removed from said supporting membenfo-r use, and to be rewound thereon when the hand piece is replaced, ,and locking means for arresting said reel, said reel including interengaging portions on said reel and a part connected with said supporting member, said interengaging portions being constructed to be disengaged by a movement of the reel in either direction.
