.ASSIGNOB T0 SAID XUNIN B'AID MCELROY WINBING DEVICE This invention relates towinding devicesv capable of Wide ygeneral use, but especially, l

ymatic brush adapted to quickly and-efficiently adapted for coiling or winding human ha1r in connection with the process of effecting socalled permanent waves. Q I.

It is an object of our invention to provide a compact comparatively simple but highly efficient winding device, which may be driven from a suitable source ofpower. and which' will permit a`n operator to control the winding of the material upon a spool by the manipulation ofl a convenientv operating handle or hand piece.

It is a further object to provide a Winding device which is connectible to a source of power such as a motor, and which is provided with a slip clutch by which a uniform tension may be placed at all times upon material wound and by which fracture or damage to material will be prevented. a J

A further object is to provide a compact,

portable winding device, the working partsy of which are enclosed in a-casing adapted to be held in the hand, especially adapted for beauty parlor work, to wind or coil locks of hair about a spool detachable from the winding shaft.

A still further object is to provide, in a device of the class described/a small casingA in the form of a handle, having rotatably mounted therein-a winding shaft 'adapted to v receive a spool and mechanism disposed within said casing for connecting ysaid winding-v 'mg end of my devlce converted into an autoshaft with a source of power. or forrigidly connecting said winding shaft with said casing and simultaneously disconnecting `said winding shaft from said source of power, thereby enabling an operator to manually wind material on said rod by turning said casing to start the winding of material, or to automatically 'windmateriaL Itis a further object to provide in a device of thefclass described, means for varying the resistance or friction of the lslip clutch to vary the tension which may be placed upon the material wound.

Another object of the invention is to'provide a small, compact, portable device adapted to be held in the hand, capable of use as a winding device and moreover having another important use or function in connection with an attachment, namely, that of an auto- ,brush out human-'hair in connection with various treatments iven by beauty shops.

These and other o jects and advantages of the invention will be apparent from thefollowing description, made in connection with the accompanying drawings, in which like reference `characters refer to similar-parts throughoutzthe several views, and in which, Fig. l is a sideelevation of thedevicewith some parts broken away on the wind-ingvvspool and on the rear connection of ,thecasingl Fig.f2fis a view mostly in longitudinall sec-`L tion ofan embodiment of the invention, some parts of the tubular sleeve constitutingcne of the clutch elements being broken away, and'some parts being shown in section;

The embodiment of our invention illuslen trated in the drawings includes a straight 'f the right or rear lend. of said casing is pro-v vided with a square plug 10 secured .within A sleeve 11 .externally threaded,screwsf' casing 8 and having a threaded circular bore into plug 10 and is adapted to abut at its inner end lthe shoulder 12a of a clutch sleeve y12, which hasi a diminished' outer `portion telescoped within sleeve'f 11 and an enlarged cy-V i Ylindnical forward portion 12"'disposed with- 16' in themedialportionof the casing 8 and mounted for free rotation within said casing.

The clutch sleeve l12 mayl have its outery end A slotted at 12c for connection with a lsuitable toothed driving head 313 rigidly connected withone end-of a fiexibledriving member 13.

" The casing 14V for the fleiiible driving `nreiiiber may be swivelly connected to the plug meinb'erlO in any suitable manner, such as in the manner shown in Fig. 1,V whereinl the casing for the fiexlble'connection 1s providedwnh a flanged bushing'YV 'swivelly connected )vith a swivel cup Z threadedly connected'with meinber11.'

' Arewinding shaft 15 is' joui'naled in the ybearing 9 and also in the medial vportion of Y the clutch sleeve 12, said winding shaft'vp'ro-v jecting from the forward end of casing `8 and terminating short of the rear end of said casing, and slightly in' advance of the slot 12c in f the clutch sleeve 12. Y Loosely mounted on shaft 15'within casing 8 is a slide block 16 of the width of said casing, and said block has' connected-therewithat its-u per surface a finger piece17 'whichpis slida le forward or backwards in therslot 8l provided in the upper face of the casing A clutch collar 18 is pinned, or otherwise fixed, to shaft 15 at the forward side of the block 16 and is 'adapted-to y.engage dogs 9* rigidly carried bythe bearing 9, the connection being made when shaft -15 is moved by the finger-'piece 17 toextreme forward position. At'the rearward sidey of the block 16, a clutchcolla'r 19 is pinned to shaft 15, said clutch collar preferably having ratchet teeth adapted to engage a co-operating clutchmember for driving only in one direction. The clutch member'19 is adapted to be drivably connected with the forward end of a relatively small sleeve 20 loosely mounted on the rear portion of shaft 15 and havin clutchvelements 20 at its forward end. The s eeve 2O is provided with a flange or l head 20 l at its rear end. and adapted to ber abutted against a concave disc shoulder "formedin the clutch sleeve,12. -A friction sleeve y21 of compressible material surrounds the sleeve 20 adjacent the rear lend thereof and is adapted to be compressed between a pair of washers 22 also mounted on sleeve 20 at theop osite ends of friction sleeve 21. Friction s eeve 21 `is of such diameter that its outer surface'will snugly fit within the clutch ortion 12" of clutch sleeve 12, and an adjusta le tensioning device is provided for j compacting or compressing friction sleeve- 21. lIt will be seen that a slip joint is provided between` the sleeve 2O andthe clutch ortion 12b of 'clutch sleeve 12 by the interposition'of saidfriction sleeve 21. This may comprise a Y nut 23 having threadedengagement with thelforward .portion of sleeve 20, anda coiled spring 24 interposed between said nut and theforwardcompression disk 22. vIf desired,

a setA screw 25 may be provided in Vnut 23 to Vlock` `the: same againstr displacement on sleeve 2O...l y

Y, In the bottom of slidable block 16, we prefer to'provide a spring pressed ball 26 adapted to engage a pair of spaced notches or Ldetentsl 27n the bottom face of casing 8v, Y 'to position, shaft l'properly in extreme -for-` ward or rearward. positions and thereby cause driving' engagement with rigidly connected with bearing 9,V as lthe case 'may be.

- The projectinv drivably retaining a'- hollowv spool S thereon andas shown a bayonet joint 'is employed including alaterally projecting pin 28 on the forwardly projecting end of shaft 15 and a bayonet slot 28 being provided in the inner end-ofthe tubular body of spool S'. Spool S is provided withfront and rear flanges or disks and the vrear disk is preferably-slotted at 29, to permitthe swinging of a retaining bar 30, which vbar at its rear end is hingedv to the rear side of said disk.

In Figs. 7 and 8"anl attachment is shown"v the clutch ,members 20aon sleeve 20 or with 'dogs 9 end of shaft 15 is 4provided with any suitable meansfor releasahly and appliedto the forwardly projecting end of shaft 15', converting the device into an auto matic brush lespecially adapted to straighten out thehair andcleanse the scalp. The brush,

indicated as an entirety by the letter B, comprises asleeve 31 adapted to readily slip over project-ing en'd of shaft 15, o n at its inner end .and having its outer en closed by any,

The operation of our device may be brieiy described as follows When one of ythe windin spools S is slipped over the projecting end o shaftl and 1vably attached thereto by means ofthe bayonet joint, the 'device may be employed'to automatically wind human hair for permanent waving. The outerend ofa lock of hair is inserted `between the retaining arm 30 and the sleeve of spool S and the hand piece 17 is pushed to extliemeforward position,there by rigidly connecting shaft-15 with the handle or casing 8. The operator may then turn the device once or twice by hand, securing the lock to the spool. The hand piece 17 may then be moved vto extreme rearward position causing clutch members 19 and 2()a to intermesh and thereby driving shaft 15 through its clutch engagement with the driving sleeve 12. The slip clutch engagement is made through the compressible friction sleeve 21 engaging the cylindrical forward portion 12b of clutch sleeve 12. In winding human hair the tension of spring 24 is so regulated by manipulating adjustment nut 23 as to apply the degree of friction desired between the 'slip clutch parts. The position of the clutch sleeve 12 may be slightly varied as desired by screwingor unscrewing the externall threaded sleeve 11. The hair or other flexible article may be wound upon spool S automatically cont-rolled by the finger piece 17 handle or casing 8 being of such size that it can be conveniently grasped in the alm of the hand with the thumb applied to nger piece 17. In Fig. 2 the device is illustrated on an enlarged scale.v

lVhen a lock of hair has been completely wound, the finger. piece 17 is drawn forward, disconnecting the power upon winding shaft 15 and rigidly connecting said shaft with the casing to prevent unwinding of spool S. The spool may then be readily detached from the winding shaft, a 'lock of hair secured to the spool in any suitable manner andthe coiled hair on the spool may be inserted in a suitable tubular heater of a permanent waving machine.

Our device may be quickly and easily converted into an automatic brush by removing the spool S and inserting the brush attachment B, sleeve 31 beingk secured by the bayonet joint to shaft 15. W'ith the automatic brush attachment the hair may be quickly and evenly brushed, uniform tension being applied without damage to the hair, due to the slipvclutch ldriving mechanism of shaft 15. In beauty parlors it is desirable to brush the hair thoroughly before separating the locks for permanent Waving vrand in treatment of the scalp for dandruf or other scalp diseases, it is also desirable vto thoroughlyv brush the hair and the scalp. With our device this may be done quickly and efficiently and without injury to the hair,- assuming that the device is regulated to inteiapose the proper friction betweendriving sleeve 12 and the sleeve 20.
