i' Application filed July 18, 1912. Serial No. 710,145.
17 70 all/whom it may concern Be it :known that l, DALLAS l?. GREEN,
a citizen of the, United States, and resident of Fort Vitayne, in the county of Allen vand State of Indiana, have,iii\f'ented new ,iication This ii'iveiition relates to devices operative by spring tension 'for furnishing power for various purposes, and particularly to reels in which a rotatable inei'i'iberis spring driven for winding up a chain or cord attached to a pair ofv eyeglasses or other article.
The invention is adapted for many uses and its object is to provide a simple and efficient means whereby spring tension is applied in a novel manner to drive a rotatable member.
ln the drawings I illustrate an adaptation of iny invention as an eye-glass reel, the reel in use being attached to the garment of the riser and the cord or chain being attached to the eye-glasses.
Figure 1 is a side elevational view of the rcel; Fig. 2, a back `view of the saine; Fig. El, an enlarged central vertical section of the saine; Fig. 4, a. section onl line ileof Fig. 3; Fig. 5, a' section on line 5 5 of Fig. 3; Fig. a nnulilication of the frame or case, and Fig. '7, a modification of the revoluble member connecting the springs.
Referring to the drawings, l() 1s a frame having an annular flange 'l1 projecting inform a spring space on said side. A rccessioi' socket 13 'is provided in the inner face of side l2 in which is revolubly seated one end of ak shaft 1l. The shaft is provided with two longitudinal slits 15 and 16' in opposite ends. The slitsare of suitable depth for the purposes hereafter described, and are disposed preferably 90o apart relatively to the circumference of the shaft. A. coiled spriiig 17 is 'operative in the space contained within flange 11, the outer end of the spring-being secured to the flange and the inner extremity being inserted in slit 15, a portion of the saine projecting through the slit and being bent bacltwardly over i ythe adjacent surface of the shaft. Any suitable manner of securing the spring to the shaft. will sufiice, the manner just described being the preferred connection.
A rotor, or chain'or cord barrel 18 is revolubly mounted on shaft 1liand vthe outer surface of flange 11 and is freely rotatable thereon. The reel barrel preferably consists of a web or dish 19 which is centrally aperturcd to permit shaft 14 to pass through the saine. On the periphery of the web is a U-shaped portionK 2() which is integral with the web and forms between-its walls the space Q1 for the reception. of the chain or cord Q2. One end of the chain or cord is secured to the barrel in a suitable manner and the other end is projected through an opening 23 in the side wall of fraine l0, which opening is provided with a reduced portion or extension 24; into which the chain or cord may be engaged, when unwound from the barrel, to retain the saine and pre-V vent the barrel :troni winding it up under thev influence of spring 17 and spring 25.
Spring 2111s contained within the space formed by the rear side of disk 19 and the portion of the bottoni 2G of the U portion 2O which proget-,ts rearwardly from the disk. The outer end of the spring is secured to said bottoni 26 and the inner end is inserted in slit 10, a portion-of said end being bent back over the shaft 14. Spring 25. it is seen from -tlie drawings, is woundv in the opposite direction to spring 17.
ln the reel adaptatioi'i of niy inveiit-ioii frame l() also forms a casing and a suitable back 7 is suitably secured thereto and the rca r end of shaft ll extends into an aperture 2S in the back. Shaft 1 4 is free to rotate in socket 13 and aperture 28 and barrel 1S is free to rotate on the shaft except as spring 25' drives the shaftl as is about to be cxplained.
lVhen the user pulls on the chain or cord the barrel is .rotated and spring Q5 is Wound up. As said spring is wound its inner end soon begins to rotate shaft 141-. at much less speed than the barrel is rotating, and the rotation of the shaft winds up spring 17, 1
lfi-aine 10. Upon releasing the cord or chai'i from said engagement the springs-drive the barrel in thei opposite direction and cause it to Wind up the chain or cord. Each spring acts independently of the other, yet `its action is coordinate and continuous with the other and the combined action produces a. uniformly continuous pressure or motive force on the rotor Within a small space.
In the application of the invention herein described I am enabled, by the use ot' two springs'arranged in parallel planes, to construct the reel ot' exceedingly small dimensions, thereby making a large saving in material as Well as greatly improvilig the appearance of the device. f
.n order that the i'naterial out of which frame 10 of the reel is made shall be thin and light I contemplate providing flange 11 on.a separate plate 29 and soldering the plate to the it'rame 'as shown in Fig. 6. ()pen' ing 30 in the plate serves as bearing for shaft 111-. I may also .secure` shaft le to .frame l() or to back 27 and revolubiy sup port thereon a sleeve 3l to which sleeve the inner ends of springs 17 and will be attached in a suitable manner as to ears 32. In either case the tension ot' the springs is effective to drive the shaft or. spindle and the rotor 1S with great accuracy and continuity Within a given space, the springs actmg independently ot each other.
.Numerous modifications ot eonstructimi and arrangement ot' parts will suggest themselves to one skilled in the art, hence l do not wish to be limited to the precise construction shown.
It is also apparent that the main feature of my' invention-the two springs comiected by a revoluble part, one spring being also connected to a iixed point and the other to a movable part or rotor-is capable of adaptation to nun'ierous uses. The reel l have herein described is only one adaptation ofthe invention.
What I claim is:
l. The combination oi a revoluble bearing, a support tor the bearing, a driven member revolubly mounted on the bearing, a plurality ol springs, opposite ends ot one spring being connected respectively to the bearing and the bearing support and opposite ends of another spring being connected respectively to the bearing and the driven member.
2. The combination of a Jframe, a member revolubly supported. by the trame, a rotor revo'lubly mounted on the member, and two springs connected to the member, one end ot' one of the springs being fixed and one. end of the other spring being connected to the rotor, the parts being so arranged that the tension of the springs is independently effective to drive thefrotor.v
3. The combination With a frame, of a shaft revolubly supported thereon, a driven member revolubly mounted on the shaft, and tivo coiled springs connected at one end to the shaft, the other end of one of the springs being connected to the driven member and the other end ot' the other spring having a conneetion'to the frame. v
el. The combination with a trame of a sha'l't revo'lubly supported thereon, a driven member revolubly mounted ou the shaft, two oppositely `coiled springs each secured at one end to the sha-tt, the other end of one of the springs being connected to the driven member and the other end of the'other spring having a connection to the frame, a cord connected to the driven member, and means in the frame to cooperate with the cord for holding the driven member in any rotated position.
Thecombination with a trame, of a shaft revolubly mounted thereon, a driven member revelubly'mounted on the .shaft and having a springlspace on one o't its sides, a spring secured at. one end to the driven member and at its other end to the shaft,
said spring being operative in said space, av
second spring having its inner end conuected to the sha ft and its other end tol the trame, said springs being operative in parallel planes.
i. The combination ot a trame, a shaft revolubly mounted thereon, a driven member revolubly mounted on the shaft, tivo springs secured to the shaft. and also to the driveninember and trame respectively, the connections being such that. as the drivenI member is rotated one of the springs is wound up and rotates the shaft to cause the other spring to wind up.
7. rlhe combination of a casing, a shaft' revolubly mounted therein, a spring connected to the shai't and to the casing, al
barrel revolnbly mounted on theshaft, a'
cord wound on the barrel and secured 'at one end thereto, and means connecting the barrel and shaft tor rotating the shaft, when the barre] is rotated, to place tension on the spring.
ln witness whereof I hereunto sign my name.
