Specification of Letters Patent.

Application filed March a, 1915. Serial 12,492;

To-all whom it may comm;

Be it known'tha't I, Gnonen Mpnnr, a citizen of the United States, resi at Washington, in the District of Colum ia,

have invented certain new and useful Improvements in Telephone Attachments, of which the following is a specification.

My invention relates to improvements in telephone attachments. V 4

The object of my invention is to provide an attachment for a desk telephone which is adapted to wind up the 60rd carrying the Wires leading to the telephone and at all 1 times keep it in a taut position in respect to its connection with the box always employed in telephones.

Another object of my invention is-to provide an attachment of. this character which' will not have a tendency to move the telephone from its placed position and yet will f at all times keep the cord comparatively taut;

-Another-6bject of my invention is to pro-I vide an attachment of this character which can be readily applied to the ordinary telephone and which does not disfigure the tele phone and at the same time provides an attachment having certain detailsof construction and operation hereinafter imore fully their disassembled relation.

Referring now to the drawingal represents the ordinary telephone which; as shown, is of the desk form, and needs no further description. The base 2 is of an enlarged form and is provided with an opening 3 through which the wires or cord leading to the transmitter and also .to the box carrying the bells, pass. In telephones of this character it is ncce$ary to have a sufiicient amount of cord leading from the base of the telephone to the box to allow the telephone to be used from any point on the desk. This large amount of cord is greatly in the way and especially when the te'ldphone is on the desk at a. point close to the 7 bell box.

In my improved attachment, as heretofore stated, the base 2 of the telephoned, is of a an enlarged form and has a downwardly extending flange 4:, inwhich is secured the base plate of the ordinary telephone; In my improved attachment, the base plate of thehordinary telephone is removed and has secured within the upper end, of the base 2 a. circular member 5. This circular member 5 is secured within the base 2 by 1 means of screws 6. and is provided with.

downwardly extending integral legs-7, to

Which are secured, by -means of screws 8,

a disk 9 which is of a diameter approximately that of the interior of the base 2. I

Secured 'Within the telephone above the member 5 is a downwardly extending arm end turned laterally p 10, which has its lower at '11, and is provided with an opening 12. The arm 10 is of such a length that the laterally turned portion thereof rests upon the upper face of the disk. 9.

Passing downwardlythrough the opening 7 12 in the arm 10, and also through an opening 13 in the disk 9, is a bolt 14, which forms the bearing for the reel '15. This reel 15 is preferably constructed of a block of wood 16, and has metal plates 17 arranged on each side thereof and extend outwardly beyond the block of wood 16 to a point close to the inner periphery of the base 2. The space 7 between the plates 17 is approximately equal to the diameter of the cord 18 which leads to the box 19 carried by the desk 20. The upper face of the outer plate 17 has secured thereto a drum 21, which has an opening therethrough, through which the bolt 14L passes and the said bolt also passes through the plate 17 and the block 16. The lower 'end of the bolt 14, below the lower plate 17,

has screwed thereon the nuts 22 and 23, whereby the reel formed by the block 16 and plate 17 are held thereon, but are free to rotate.

Secured to the lower face. of the bottom plate 17 is the inner end of the coil spring 24:. This connection between the spring 24 and the reel is by means 'ofa staple 25. The outer end of the coil spring 2t is secured to theplate 26 and. forms the base of the telephone taking the place of the usual base now used. This connection between the outer end of the spring and the plate 26 is made by striking the metal of the plate upwardly, as indicated at 27, and passing the wire loop 28 therethrough so as to secure the said loop to the plate, and the said loop in turn is secured to the free end of the coil spring. The center of the plate 26 is provided with a central upwardly pressed portion 29, having an opening in its center through which the bolt 14. passes. Screwed upon the outer end of the bolt, on the outside of the plate 26, is" a nut 30, by means of which the plate is secured to the bolt. The outer end of the plate 26 is provided with an upwardly turned.

flange 31, and resting on the said plate on the inside of the flange is a cylindrical shaped member 32. The upper end of this member 32 enters the base 2 of the telephone on the inside of the flange 4. By th1s arrangement, it will be seen that the entire reel, spring and other parts of the attachment are wholly inclosed within the base and forms a very neatappearance only add ing about an inch and a quarter to the height of the telephone The cylindrical member 32, at one side is provided with an opening 33 having a spun. portion 34 there-,

around which forms means for allowing the cord to freely pass through the opening without injury thereto. 'The cylindrical member 32 is clamped to the base by means of the plate 26 and the nut 30, as clearly shown in Fig.2 of the drawing.

The cord 18 passes from the block 16 through the opening 33 and is wound upon the block 16 between the plates 17 The inner end of the cord passes through an opening 35 in the upper plate 17 and is coiled upon the drum 21,. and passes upwardly through an opening 36 in the plate 9 and then upwardly-to the telephone in the on the drum 21 and thus, as the drum is un- I usual manner. In Fig. 2, it will be seen that there are the same number of coils of the cord between the plates. 17 as are arranged wound," the cord unwinds therefrom. The relativesize of the drum 14 and the block 16 allows enough cord to be withdrawn from the base of the telephone to enable the use -of the phone at any point on the desk.

When more cord is necessary an extra coil is made upon. the drum 14 and also upon the block 16. The spring 24, as will be readily understood, rotates the reel so as to cause a constant tension upon the cord 18. The ten sion of this spring is only sufficient to wind the cord, but not to disturbthe position of the telephone on the desk or other support upon which it isused. lVhen the tension of the spring 24 'is notsufricient to wind the cord, the nut 30 is loosened and the plate 26 is turned and having one end of the coil spring attached thereto, it will be seen that "I claim as new and desire to secure by Letters Patent, is

1. The combination with the base of, a

desk telephone, of a cylindrical member within the base and extending below the same, a rotatable plate closing the lower end of the cylindrical member, a reel-within the cylindrical member and upon which is wound the cordleading from the telephone to the bell-box, a spring having one end secured to the reel and the opposite end to the plate.

2. The combination with a desk telephone of a cylindrical member secured to the lower end and forming the base, of a spring wound. reel within the cylindrical member, and having a drum on its upper face, the cord carrying the Wires leading from the telephone wound upon the drum and passing to the center of the reel and wound thereon and passing outwardly to the bell box, whereby a constant tension is kept on. the cord between the bell box' and the telephone.

, 3.. The combination with a desk telephone, of a cylindrical member secured to the lower end thereof and forming the "base, of a spring wound reel. within the cylindrical member, and a drum carried by the upper.

face of the reel and upon which is coiled the cord leading from the phone and carry ing the wires, said cord passing from the drum to the inner periphery of the reel and wound thereon and passing outwardly the telephone, a horizontally arranged reel withinthe cylindrical member, a spring for winding the reel and having one end con- The combination. with a desk telephone nected to the cylindrical member, the upper end of the reel having a drum secured thereto and upon which is wound the cord carrying the wires from. the phone and I said cord passing from the drum to the inner periphery of the reel and wound thereon and passing outwardly through the cylindrical member, whereby a constant tension is kept upon the cord between the telephone and the bell box. v

In testimony whereof I aflix my signature in presence of two witnesses.
