To all whom may concern:

Be it known that-I, Mme F. MORAN, a citizen of the United States, and'residen'tof East Lynn, county of Essex, State of a Massachusetts, have invented an Improvement in Strip-Winding Mechanisms and Reels, of which the following description,

in connection with the ace mpanying drawing, is a specification, like'characters on' do .the drawing representing like parts. I '1 This'inverition. relates to improvements in stripwinding mechanisms-and reels. for

' receiving and for delivering coiled strips of material, and the principal object thereof is to provide means for winding a strip ofmatenal, such as a moving picture film, in a suitable reel from the outside toward means for transferring the wound spiral strip to a suitable strip delivering reel,

-meansalso preferably being provided for I retaining 'thecoiled strip upon the delivering reel.

. Moving picture films are coiled upon a reel from the center outwardly and when placed in a moving picture machine are unreeled and passed across the projecting apparatus whichthrows the picture upon the film. After leaving the projecting apparatus the '30- film has heretofore been coded upon a sec-.

' and reel from the center outwardly. Thus the initial portion of the begins at the center of the reel and necessitates the re-winding of thefilm in a reverse direc- ,tion in order that the film maybe in posi- -tio n to belagain used in themoving icture machine, This entails a cons! erable: amount, of time and labor and produces ;,-more or lessiwear upon the film;

1; The principal b]ect of, the present "invent-ion is to provide means for winding the film-upon a reel after it has, assed through --the' projecting apparatus-of t 'e' moving p cturemachine beginning. at" the. outside and 1'4 winding toward the center-of the reel, so

- h the film in condition be at. once wound upon the reel.

ings and will he pointed out in the accompanying claims; 'A preferred embodiment of the invenition-"is illustrated herein as adapted to'reused in the moving picture with i out the necessity of re-windingg. "-1 By thus avoiding re-winding of the the danger of ignition .of the film is greatly reduced since it is not exposed to heatand, sparks as is some times the case where the- .fihn is re-wound. A further object of the invention is to provide a particular form of reel in which the film may be conveniently wound toward the center. p

- Another object of the inventionis to provide means for tightly winding the film, or other strip, from the periphery toward the 0 center'of the reel.

' Another object of the invention is to pro- 5 videm'eans for tighteningthe winding of. the'center of the reel and also comprises the film upon" the reel after a predetermined amount has been wound upon-it. 1

A further object of the invention is to' provide a: strip winding machine in which the strip-receiving reel can be readily re moved from the winding mechanism.

A further object offthe invention is to provide a strip "retaining. device for the strip delivery reel .which will overlie the exposed edges of the strip and. prevent the" 'same from l displacementwhile the reel is Jb'eingItra-nSPQrtedIfrOm place to place.- 86

The present provision of means for winding a;str1p,i

I j such as; the strip of a moving picture film,

as it comes. from the moving plcturemachine, upon a reel in which s irals, of the strip are laid upon the reel omtheperiphery toward the center, means being provided for progressively pressing and retaining the lower edge of the strip asit I is of a suitable contactswith the base of the reel firmly against thenextouter spiral. ,This is accomplished by supporting the strip receivingw'reel upon a rotatable-conical winding member in which the surface of-the cone pitch which will cause its surface progresslvely to .contactwith the lower edge of successive spiralsas they are wound upon the reel and will act to press the lower edge of the spiral'tightly-against the next outer spiral and also to maintain such pressure untilthe entire coil has beenwoun The invention further contemplates the provision of means for positively driving the conical member of the strip winding mechanismand automatically governing the speed of rotation of-said conical winding member in correlation to the spiral which is being wound. To accomplish this 'urpose the reel supporting member is gra ual- 1y elevated'a's the spiral is being wound and side elevation of a winding.

invention contemplates the",

. rotated in a mechanism is provided which is actuated by the upward movement of the reel suping mechanism toward the axis of the reel supporting means.

A preferred embodiment of the inven tion illustrated in the accompanying drawings comprises a frame having a base 1 porting mechanism to shift a frictional driv- 2 from which rises an upright post 2 which I is provided at its upper end with an overhanging arm 3 in parallelism with the base 1 0f the frame andwhich serves to support a guiding device for the upper end of the elevating rod of the winding mechanism. A standard 4 is suitably secured to the base and extends upwardly therefrom and is provided with a socketed upper end which receives trunnions 5 of an upper section 6 in the form of a spider having laterally extendingarms 7, preferably three in number, provided at their ends with bifurcated bosses 8 having anti-friction roll ers 9 which engage and support the base 10 of a conical winding member.

A bracket 11 pivotally mounted upon a screw or stud 12 in the standard 4 under- .reel the bracket 11 is swung aside about its pivot 12 so as to permit the spider to be swung upon the trunnions 5 into substantially'vertical position, permitting the reelto be removed from the conical support as will hereinafter be more fully described.

ada ted to receive the arms 15 of the receivingvreel spider so that the receiving reel spider'may be raised upwardly while being unison with the rotation of the conica'lwinding member. Thearms 15 of the strip receiving reel are inte ral with a central disk 16 to which is allixed a hub 17 having a screw threaded central por tion which engages a" screw threaded elevating rod 18 which is fixedly secured in the hub of the spider 6 by a "set screw 19. Both tlielower and upper portions of the elevat -ing rod 18 preferably are not screw threaded. The .outer endsv of the arms 15 of the reel dem'rably are integral with a flat annular rim 20 which is rovided with tabs 21' which overlie and our! guides for a The conical winding member comprises a .shell 13 having a series of guiding slots 14 extending upwardly from its base and flange 22 of a peripheral strip retaining -means such as a. ring 23 which is of the same or slightly greater height than the width of the film to be wound. The .pe-

is rotatably mounted upon the'rim 29 of "the reel spider.

,ripheralstrip retaining ring 23 therefore,

sirably' is-. provided with arms .24 which e'x tend inwardly a short distance and rest upon the arms of the receiving reel spi er The arms 24, therefore, lie within the guiding slots 14 of the conical winding member 'when the reel is at the base of said conical winding: member and remain in said slots during a portion-of the elevation of the reel during the winding operation. WV hen, how-- ever, the reel is raised sufficiently, the ends of the arms 24 will not extend into the grud- .ing slots 14 and when thus released the peripheral strip retaining ring23 may be rotated independently of the rotatlon of the spider. -Means are provided for produclng such relative rotation during the latter-portion of the winding of the film for the purpose of tightening the spirals of the film within the reel as will hereinafter more fully appear.

As before stated the hub 17 ofthe reel is mounted upon and has screw "threaded renigagement with the stationary elevating rod 18 so that therotation. of the, coneand reel margin only of the lower edge of the successive spirals of the strip are progressively pressed against the" next outer spiral by the cone, so that the film is wound tightly from the outside toward the center. By reason of the fact that the conical winding member engages the strip only at the margin ofthe lower edge as it" progressively winds the spirals upon the reel from the outside toward the center theiiaof contact with the face of the strip is avoided. Thus where a.

moving picture film is wound bearing a series of p ctures injury to the picturesor scratching of the face of the strip is prevented.

The upper end of the elevating rod 18 is V journalled in-a sleeve 27 (see Fig. 4) which desirably may be-in the form of a pipe section havingits' upper end screwed into, the overhanging arm' 30f the main frame, The lower end portion of the pipe 27 isprovided with a slot 28 adapted to permit 'the'elevating rod to be removed laterally when it is desiredto tilt the winding device -for the purpose of'remo'ving the reel. Inorder to confine the upper end of the elevating .rod

in its bearing asleeve 29 is rotatably mounted 'upon the pipe 27 and is provided witha slot adapted to-be rotated into registry with theslot 28 when the upper end ofthe, elevat .ing rod is to be'removed or to be rotated into a position to close said slot during the reeling operation.

In order to hold the sleeve 29 inplace the low'er'end of the pipe 27 is provided with an outwardly extending flange 30. As the progressive winding of the reel produces spirals diameterit is desirable that'means shall be provided to produce a rotation of the winding mechanism in correlation to the decreasing diameter of the spirals of the strip or film. This is accomplished in. the present .invention by providing means governed by theelevation ofthe reel tor shifting a trio .of constantly but gradually decreasing tional driving mechanism progressivelytoward the axis of the winding mechanism. In the preferred construction illustrated herein the hub 6 of the reel is provided with two concentric supporting members 31 and 32 which are rotatable within a relatively stationary cap which is actuated by the elevation of the reel to shift the frictional driving mechanism. I

As illustrated in Fig. 5 the cap comprises two annular plates 33 and 34 which clamp between them the flange 35. of a cylindrical member 36 which encloses the outer supporting member 32; .the - disks 33 and 3% being secured together by suitable bolts or screws. The cap-is provided with a slot 37 to permit it to be swung laterally when it is desired to tilt the conical winding mechanism into position to permit the removal of;

the reel.

The "disk 34 of the cap is provided with upwardly extending bosses 38 in which standards 39 are secured at their lower ends. These standards are p-ivotally connected at their upper ends to the lower ends of levers- 40 which are fulcrumed about midway of their lengths upon a pivot 41 carried by a link or links 42 which are pivotally mounted upon their upper ends upon studs 43 carried by a bracket 44 having a sleeve 45 which is slidably mounted upon the sleeve 29 which surrounds the pipe 27 forming the guide for the upper end of the elevating rod.

The spiral movement of the reel is translated through the lever 40 and other mechanisms hereinafter described into a move'- ment' which shifts a frictional driving wheel, which engages the base ofth'e conical winding member, jfromsthe periphery toward the axis of'said winding member-in correlation to" the decreasing diameter of the spirals of the strip being wound. In order 1 I to maintain'the proper correlation between the drivingmechams'm andthespirals-of the strip being wound it isnecessary to accelerate the movement of the frictional driv big wheel toward the axis of the winding mechani m asnthe spirals of thesstrip-prmgressively' decrease in iam'eter; This is accomplished in the pre erred embodiment of the invention illustrated herein by the following mechanism. -The.upper ends of the levers 40 are pivotally connected to the lower end of a lever 46 which is fulcrumed upon a stud 47 on a carriage 48. The carriage is preferably mounted upon a track 49 and is provided with anti-friction rollers engaging each side of the track. As the lever. 40 is raised by the elevation of the reel it moves the lever 46 end-wise, thus moving the carriage along the track 49. At thesame time the lever 46 swings about its pivot 47.

The lever 46 is provided with a laterally extending end 46 having a cam slot 50 inwhich a stud 51, which forms the fulcrum of a lever 52,. is slidably mounted. The

lever 52 has a laterally extending end 52 yvzhich is provided with a stud which extends 1 to a slot in the end portion of a link 53. The opposite end of the-link 53 is pivotally connected to a stud 54 upon the end of the extension 46* of thelever 46.-

Durin'g the relative movement of the end 46 and 52 of the levers 46 and 52 respectively the link 53 engages the pivotal stud 51 Which'forms the fulcrum of the stud 52 and forces it along the cam slot until at the end of its movement it finally is lodged in an offset end of said slot. By thus shifting the pivot 51 ofthe lever 52 the lever 52 is given a progressively increased end-wise movement which provides the necessary ac-' celeration of the movement of the driving wheel toward the axis of the winding mr her when the relatively small spirals of .1 strip are being wound" ,The lever 52 preferably'is made adjustable in length in orderto permit the driving wheel. to be; properly positioned in relation to the base of thewinding member. As illustrated herein the lever 52/ is provided with an adjustable section 55 in the form of mg from the vertical standard 2 of the.

"'end to one or bot 60.

a rod which is slidably mounted in an upturned flange at the end of the lever 52 (Fig. 7 The end of the rod 5 5 is bent-at right angles to its axis and passes through a slot in the lever 52, a winged nut 55* upon the screw threaded end of the rodservmg to clamp the same in adjusted position. The opposite end of'the' rod 55 preferably is detachably connected by a bayonet andslot connection 56 to an arm 57 .which is pivotally mounted upon a shaft 58 which is journalled in arms of. brackets 59 having vertical sleeves which are slidably mounted upon guide rods 60 carriedby brackets 61 extendframe. A spring162,-.connected at its lower its upper endto an arm extending fromthe side frame 2,"tends normally to raise said brackets and thereby to move the frictional drivingwheel toward the periphery of the 7. base of the winding member as will hereinafter-more fully appear.

The driving shaft has secured to it a belt pulley 6S and also has slidably mounted upon it a frictional driving wheel 69 preferabl having, a suitable tire 7O which'engages t e under face of the base 10 of the conical winding member. The frictional driving wheel 69 is slidably mounted upon the driving shaft, but is caused to rotate therewith 'bya feather carried by the hub of the wheel which engages asuitable slot 71 in the driving shaft. The hub of the pulley 69 is provided with an extension having an annular groove 7 2 which is engaged by a flange at the end of a carriage which. comprises a sleeve slidably mounted upon the driving shaft and having legs. 75 and 76 which are provided at their lower .ends with rollers 77 and 78 which travel upon guide rods 9 extending horithe driving shaft.

In'the operation bf the machine the upward movement of the reel acts through the non-rotatable cap 36 to raise the standards 39, thereby As the upper end of the lever 40 is connected to the lever 46 it causes the latter toxmove end-wise during the first upward movement, thereby forcing the carriage 48 laterally. (to the left). At the same time the lever 40,

'moving the, lever 40 upwardly.

acting throu h the link ,42, raises the sleeve 45 "until the latter engages the horizontal arm 3 of the frame. Further upward movement of the reel after the sleeve 45 has thus been seated against the arm 3 causes the link 42 to swing the fulcrum 41 of the lever 40 laterally,- (to the left). This produces a continued movement of the carriage 48 to the left. I

During these movements of the lever 46, the extension 46 of the lever 46 is swung downwardly carrying with it the end of the 1ink'53 which is connected'to it. main portion of the lever-"46.v approaches As the horizontal position the central portionot the link'53 engages the stud 51 which forms the fulcrum of the lever' 52 and further pivotal movement of the'lever 46 causes the link 53 tolforce'said pivotal stud lengthwise of the slot 50 until iteventually reaches the end of said slot and enters the Offset portion thereof. of-these movements of the 40 for the winding mechanism, is then swung aside and the conical winding member tilted:

This is accomplished in the present invention by .driven by 14 in the conical windin causing a difi'erential'rotation ofthe peripheral'strip retaining ring 23 which engages the outer spiral of the strip relatively to the conical winding member after a predetermined portion of. the strip has been wound. It will be remembered that the peripheral strip-retaining ring 23 is rota-- tably mounted upon the disk 20 within the keepers 21. The differential rotation is im-- parted to this eripheral strip retaining ring by means 0% a pulley having a frictionally driven rim which engages the erim 80' is mounted upon a series of radial, plungers 81 slidably mounted in guideways 82 in a cylindrical pulley 83 having a hub 84 which is slidably feathered upon a shaft 85- which is journ'alled in suitable bearings, (not shown). Springs 86 located in the guideways 82 serve to force the plungers 81 outwardly into frictional engagement with the pulley rim 80. The shaft 85 isprovided with a suitable sheave or pulley which is engaged by a belt 87 l which passes over idler pulleys 88 and is a pulley 89 upon the main driving shaft 65.'- V

During the early: part of the winding movement the arms 24 which are connected .to the ring 23 are located in the slots 14 in. the conical'winding member and the rin 23 is rotated in unison with the conica member irrespective of any action of the rim 80 of the tension pulley. During this ,time the tension pulley 80 rotates upon the riphery of the ring 23. The pul eyperiphery ofthe ring without having any influence upon it. When, however', the reel .has'been elevated sufliciently to cause the arms 24 of the reel to pass out of the slots member the tension'pulley 80 will rotate t e peripheral strip retaining ring 23 somewhat faster than the rotation of the winding cone, thereby im posing a greater'tension upon the wound film during the latter portion/of the winding'movement. By reason of the frictional engagement between the plungers 83 and the rim- 80 of the tension pulley any desiredamount oislip'page ma be given to the rim" 8,0 of the drlving pul ey so that a proper amount of tensionma be ap liedjto the film when under the i' uence 0 this tension,
