Imp-arm n Application filed July 21,

To all whom it concern:

Be it known that E, DAVID Sworn. a citizen of the United States, residingat Mercliantville, in the county of Camden, State oi" New Jersey, hero invented a. new and useful Automatic" Tulle-Up Attachment for Portehi.e-".ielephonc Conductors, of which he followii is e specification.

' or extension telephones for Lcnces and other which are to he transported from one room to another from one desk to another. or s downstair or vice versa, es in of on extension house pnone, there is always considerable length of loose cord. or slack telephone wire intermediate the portable telephone. and the signal box which is liable to he tripped over, or become enuglcd with V3.1 o'us objects. and the object or my invention is to provide a. novel, neat and simple appliance whereby said loose or slack Wire or cord will be automatically hep-t tent or reeled up at all. times and yet be capable oi being readily unreeled when l is desired to move or change the position oi the extension telephone, as from one desk to another, or from one room to another, provision being made for enabling said slack cord to be automatically Wound upon :1 suitable reel Without cutting or interfen ing iii-any Way W'th the cord or installation of the telephone company, provision being made for the slack cord to automatically kept taut, or wound u under a slight tension so that the telephone will not be moved from its temporary position and the liabiiity of the breakage of the instrument or other object by the entanglement of the loose cord therewith is entirely obviated.

My novei take up device is entirely autorustic in its operation, can be readily installed. Without the employment of an electrician or skilled labor, can he cheaply inanufactured, as the number of parts is reduced to a minimum. is not liableto get out of order and will be tioilnd to he eilicient and serviceable under sli conditions.

For the purpose of illustrating m3: invention, I have shown in the accompanying drawings one form thereof which is at present preferred by me. since the some will he found in practice to give satisfactor suits although it is to he understood that the various instruinentelities of which my invention consists gun cs variously arranged and organized and that my invention is not Letters Petcnted 1916. serial No. 110,425.

limited to the precise arrangement and organization of these instrunientslities herein shown and described.

Figure 1 represents a. perspective'view of an automatic take-up attachment for extension teicphone ei'nhodyiug my invention.

Fig. 2 represents a section on line 2-2 of Fig. 3.

Fig. 3 represents :1 plan View cl Fig. 2. the top of the her; being removed.

Fig. at represents a section elview partly in elevation of another embodiment of the principle of my invention.

Fig. 5 represents an end elevation of a portion of the boX and reel seen in F 3.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to drawings:

1 designates the line Wire which leads to the signal box 2 of a subscribers desk and is of the usual construction, from which box leads the Wire, conductor or cord oi? the extension telephone at, which latter isyoi? the usual construction and requires no detail description.

The cord 3 is dropped into a recess 5 in the box 6 which may be of rectangular or other shhpe supported upon a table as indicated at 7 or attached to :1 side Wall or any other desired point. The cord utter being passed through the recess 5 is held in position from longitudinal movement by e. staple 8 and then Wound as indicated at 9 around the hub or spindle 10 which curries the hollow reel 11 of enlarged diameter.

Within the chamber 12 of the reel 11 is located the spring 13, which has one end 215 lei secured to the reel 11. while the other end of said spring as 15 is secured to the spindle 10, as will he understood from F 2.;

The outer terminals 16 of the spindle 111 have their opposite sides flattened or par allel and are adapted to he dropped into the recesses 17 in the sides 28 of the box 6. so that it will he understood that after cord has been loosely Wound around the spindle 10, as indicated at the top of Fig. 3, and then Wound in the reverse direction around the reel portion 18. as indicated at 19 in Figs. 2 end 3. the free end 20 of the 'cord will lead to the telephone stand l. I

preferably insert staple or other fastening device. indicated at??? in Fig. 3 into the reel body 18, sothet an zipproxiniiotely Prods termined fixed length of cord may be W eund on the-huh l0 and reel 18. The parts Will 2' 2, Hills,

now appear as seen in Fig. 1, it being understood that the spindle l and the reel ll. are preferably removed or lifted upwardly from the box 6 during the act of winding up the shack cord upon the hub and reel 18, the spindle portion 10 being held stationery in. the hand of the user and the reel member 18 having been turned against the tension of the spring 13, so that when the spindle l() is dropped into the box (2, as indicated in Figs. 2, 8 and 5, any pull upon the cordQO in the direction of the arrow a will automatically permit the cord 19 to unreel from reel 18 end when the user is through talking on the telephone, and replaces it in its desired position, the tension of the spring 1 5 will he s i ticient to reel up the cord 20, the spindle l0,

iii;

till

reel ll and the square terminals 16 operating in a manner somewhat similar to a. curtziin holder, and the tension of said spring being only suiiicient to effect the de sired reeling and unreeling of the cord or conductor 20.

It will thus be seen that under all condi- Q tions my novel device is automatic in its operation and can be attached to any telephone having an extension cord Without cutting or interfering in any way with the connection or installation of the telephone company, the slack cord at all times being czipaole of being unreelcd, according to re (.guirenients, undbeing automatically reeled or Wound up and kept eufliciently taut w1thout requiring any attention on the port or" the operator.

in practice, I cover the l3OIi'6 containing the tzilte up mechanism with it suitable cover 5-31. which can be secured in position by suitable hitching or locking devices 22, said hot:

llllw'lllg' an elongated slot 23 therein to permit of the necessary lateral unreeling of the cord 20.

in the construction seen in Fig. 4:, I have shown another embodiment of the principle of my invention. wherein the spindle 2% is. shown, us formed of a shaft supported from the side oi the box 6 at the point 26, the general in illllCl' of constructing and collocnting the spring 13 with respect to the reel il being as already described, the cord from the signal box or subscribers desk being indicated in Fig. 4 as 3, the slack cord as 27, the cord on the reel as 19, and the cord leading from the reel to the telephone us 530, as already described with reference to Figs. 2 end The i'nunner of operation of the structure seen in Fig. i will be readily apparent to those skilled in the art from the foregoing description, as it will be apparent that o pull on the cord 20 will serve to unwind the reel. 11, xii eupon when the cord 20 is released, said cord will be automatically wound on the reel and kept tout as is evident.

It will be understood that t], suitable cover or top 2111 be provided as in 2, as already explained with reference to Figs. 2 aud o, and that in all the embodiments of my invention, my novel take-up device dispenses with complicated and expensive genring which is liable to get out of order and can. be readily attached lo or used in conjunction with any extension telephone hav ing on extension cord, without necessitating the employment of an electrician or skilled labor, and without necessitating the cutting of the slack cord or interfering with the installation put in by the telephone company.

It will be seen from the :t'oregoin that my novel device can be readily ettec led to the slack cord of any extension telephone, without cutting or in any. Way interfering with the telephone companysinstallation.

it is further entirely automatic in its action, and the box containing the n1echonism can be fastened out of the way to o well, desk, table or other support.

It will be further apparent that the reel 18, which is of considerably larger diameter than the spindle 10, can be so proportioned us to have Wound thereon a greater or loss length of cord 19, according b0 the len th of cord which it is desired to unreel. Iv y device is especiully useful in extension telephones for residences, Where families at night on'retiring take the telephone upstairs, in which case unless u device of the character of my invention is employed, there is liable to be a. considerable length of one cord, which is liable to be tripped over in the dark, all of "which is obviated by my invention.

Having thus described my invention, What 1 claim new and desire to secure by Letters Patent, is

1. In an automatic take-up device for the cord of an extension telephone, a. spindle, 2:. reel rotatably mounted on said spindle, a spring intermcdia-te said reel and spindle, a telephone cord wound on said reel in one direction and having an extended spare length' wound in the reverse direction on said spindle, whereby it predetermined length of cord may be unreeled, and 2t telephone connected to the outer end of said cord extending from said reel.

2. in an automatic take-up device for the cord of on extension telephone, at spindle, means for preventing said spindle from rotation, a. reel rotatably mounted on sold spindle, a spring intermediate said reel and spindle, a telephone cord wound on said reel in one direction and having an extended spare length wound in the reverse direction on said spindle, whereby said telephone may be readily moved toward and away from said reel, and u fastening device for said cord intcrmedittte said real and spindle, and secured to said reel body, whereby it prospare length wound in the reverse direction 10 on sald spnidle,

whereby a predetermined length of cord may be unreeled from said reel, said box having an inlet opening for the cord wound on said spindle, and an outlet opening for the cord extending from said reel, said latter cord being connected 15 to said telephone.
