-My invention relates to rotating brushes, butliiig wheels, polishing wheels, .grinding wheels, etc., and to means for holding and driving such brushes and wheels.
rl`he principal objects of my invention are, to provide improved means for permitting one brush or wheel of the character herein et forth to be removed from a rotating holder or driving shaft, and another such brush or wheel to be substituted therefor,
Vwithout stopping the rotation of the said provide an improved porta-ble holder or driving shaft for brushes and wheels of the characters herein -set forth, and an improved han-:lle -portioii for such portable holder or shaft; to provide improved flexible driving mechanism for the Vaforesaid portable holderor driving shaft; and vto provide other iinherein set forth.
proveinents in apparatus of the character Other-objects will be apparent from the following disclosure of the invention. Y
"Gn the accompanying sheet of drawings, illustrating one forni'of my invention, Figlurel is a longitudinal sectional view of one foi'in vof portable rotating-brush or rotatingwheel holder of this invention, with portions shown in elevatioii,the said holder carrying a removable brush or wheel ofthe characterV herein setforth Vwhich is'also shown in crosssection; Fig. 2 Yis a sectional-elevational view p of a portion of a flexible shaft connected to aniotor armature, anda portion of a flexible casing for the flexible shaft Vplayably. connected to the motor frame; 3 is a crosssectional'view of the device shown in Fig. l, with the' rotatable brush or wheel removed, talzen on plane 3-3 of Fig. l; Fig. l is an elevational view of one of the hub end-plates on the rotatable brush or wheel structure of Y Fig. i; Fig. 5 is across-sectional view of the rotatable driving shaft ofthe device of Fig. l, taken on planei-pofliig 1, with` a portion shown in elevation; Fig; 6 is a side-clevational view of the spring-controlled trigger carried by the rotatableV driving ,shaft of lthe device of 'Fig'. l, showing the relation of the said trigger to the said rotatable shaft;
and Figi. is a cross-sectional view oftherotatable driving shaft of the device of Fig. ,1, taken on plane 7 7 of Fig. l. Like characters refer to like parts inthe several figures of the drawings. y y n In the use of ordinary rotating brushes, buflfing wheels, Vpolishing wheels, grinding wheels, etc., it is necessary to stop the rotation of the driving shaft carrying sucliibiush or wheel when itis desired to substituteV one brush or wheel for another, and to nianipul late a nut tof'perinit such substitution to be iiiade. AStopping the rotation of the drivv`ing shaft of course necessitates bringing the said shaft up to the proper speedlagain Vafter Y tliedesired substitution of the proper brush or wheel is inade.
nipulating the said nutfconsurnes considerable time, especially where `one brush or wheel is substituted for another quite frequently, as, for instance, in shining 'orpolishingshoea This stooiiino' and start- J, La 1 t; Y ing or tue driving shait, together with ina y and in doing/various other buiingand polishy ingjobspl f i in my vpresent invention I'. havefdevised a characterr herein set forth may bev [quickly and easily substituted for another such brush or wheel on a driving shaft without stopping thell rotation of the* driving shaft -or having Vto nianipulatea nut.vk Such a device entirely device whereinlone brush Yor `wheel of thev overcomes the disadvantages above mentioned and consequently saves considerable time that heretofore was wasted. Y The convenience and advantages of such an improved device are therefore thought to be very apparent.
I will now describe my invention more in detail by reference to the embodiment thereof disclosed in the accompanying drawings.
Referring to the drawings, .1 is a flexible shaft and 2 is a flexible casingtherefor.v One end of the flexible shaft 1 is connected to the armature of an electric motor 3, preferably as shown, so that when the said armature rotates it rotatably drives the flexible shaft 1. The member 4 is soldered or rigidly attached to the motor end of the flexible casing 2, and is loosely connected to the frame of the motor 3 by bolts 5, 5, preferably :as shown, so asto n hold the flexible casing 2 against rotation but permit it to haven-nd play relatively to the y flexible shaft 1. The end play of the flexible casing 2 permits the flexible shaft 1 and casing 2 to `be more easily bent to various positions during -the use of the flexible shaft 1. 6 is a hollow handle portion whichis securely attached to the end of the flexible casing 2 away from the motor 8 by means of afportion 7 which Vis soldered or rigidly attached to the exible casing 2 and screwed to the portion 6, preferably as shown.` 8 is a driving shaft which 'is rotably mounted inside of the handle portion 6 in suitablebearings 9, 10. The sha-ft 8 projects from the free'end of the handle-portion 6 preferably as shown, and is-held against' any appreciable end movement by ilow hub .portion 16 adapted to slip over theY means-of the bearing 9 and the 4portion 7 cooperating with fan enlargedl end portion 11 thereof. The end of the vflexible'shaift =1 away fronrthe motor 8 terminates in a pin 12 which is rigidly secured tothe shaft l'preferably by solder and has a flat side `13. The pin v12 is rotatably located inside of the handle portion 6*,.and projects into the driving shaft 8, preferably as shown. The shaft 8 is provided with a flat side 14 toward the inner endthereof, which co-operates with the flat side 18v of thelpin 12, as shown in Figs. 1 and 8, where- 'by the flexible shaft 1, when-rotated, causes the 'driving shaft k8 to rotate therewith. It will be understood that the flexible shaft 1 and the flexible casing'2 of Fig. 1 are contin- -uations'of the flexiblelshaft 1 andthe flexible casin'g2, respectively, of Fig. 2. 15 is a rof'fatable -brusli,'bufling wheel, polishing wheel, grinding wheel,or other wheel, havinga holprotruding end 17 of the driving shaft l8. The hubr'portion 16 is 'provided wit-litransverse annular recesses 18, 18 in the inner surface :thereoffat the respective ends thereof. The -fhub portion 16 also carriesfend plates 19, =1-9,.each plate19 being provided with inwardly--projecting` portions 20, ..20 which lextend into the corresponding annular recess 18.
21 is a trigger which is pivotally mounted at 22 in a slot 28 in the driving shaft 8. 24 is a coil spring which acts on the trigger 21 so as to cause a portion 25 of the trigger 21 to normally project out from the side ofthe driving shaft 8. l/Vhen the brush or wheel 15 is placed onto the protruding end 17 of the driving shaft 8, to the position shown in Fig. 1, with either end of the hub structure 16 placed toward t-hev handle portion 6, the end plate 19 which is nearer the handle portion 6 first depresses the project-ing portion 25 of the trigger 21 to a position within the connes of the driving shaft 8, which permits the said end plate 19 to pass over the portion 25 of the trigger 21, after which the spring` 24 causes the portion 25 of the trigger 21 to again project out' from thc side of the driving shaft 8, this time intothe annular recess 18 Vin the end of the hub structure 16 nearer the handle portion '6, as shown in F ig. 1, whereby the Ybrush or wheel 15 is, securely retained on the d-rivijngshaft. 8 yand locked thereon.` Now when the driving shaft 8. is rotated, in either direction, the projecting portion 25 of the trigger 21 laterallyengages one of the portions 20, 20 ofthe hub structure ofthe brush v(za-wheel 15, in the yannular recess 18 into which the portion 25 :of the trigger 21 projects, and thereby ldrives the brush or wheel 15 .with the driving shaft v8. The two end plates 19, 19, at opposite ends of the hub structure 16, permitthe brush orwvheel 15 vto be reversed, or turned end-for-end, on the driving shaft 8, thereby, in effect, reversing the drive on thebrush or wheel 15. 26 is a springcontrolled manually-depressible member which extends into the outer end 17 of the driving shaft 8 and at the Sametime projects from the end 17 of .the shaft v8. The coil vspring 2.7 tends to force ,the member 26 out ofthe end 17 of the shaft 8, but the pin `28 limits theoutward ,movement of the member 26. The outer end of thermemberr26 is provided with a convenient cap 29 adapted to slide farther into the-hollow Yend 17 of the shaft 8 when depressed. rEhe cap 29 is preferably-loosely attached to the member 26, so
that whendepressed while the member 26 is rotating, the ,pressure thereon lwill hold it from rotating and thus prevent it from rubbing on the member ,pressed thereagainst. YVhen the member 26 is depressed farther in to the shaft 8,.preferablyby pressing onthe cap 29 with the palm of the hand, or in anyv other suitable manner', either while the Ashaft 8 is rotating or 'while it isy stationary, the inner end of the vmember 26moperates with thetrigger 21, as thought to be well understood from'the drawings, and `moves the trigger 21 L fromfthe position 30 to the positionl', 6,
lin which latter position the por-tionr25 of the trigger vis .brought t0 a` Aposition within the confines of the driving shaft 8. Bringing the Vprojectingportion 25 of ythe trigger 21 from the position shown in l to the position 31 shown in Fig. 6, relatively to the drivingshaft 8, releases the drive on the brush or wheel l and simultaneously unlocks the brush or wheel holder, thereby permitting the brush or wheel to be stopped, when rotating, and removed from the protruding end 17 of the driving shaft 8 without rotating, while the driving` shaft 8 continues to rotate. rI`his permits one brush or wheel 15 to be substituted for another such brush or wheel on the driving' shaft 8 without stopping the rotation of the latter. Of course such a substitution may also be made while the driving shaft 8 is at rest. The advantages derived from such a device are thought to be now well understood.
I do not wish to limit this invention to the particular details herein set forth, as many modifications thereof may be made or utilized without departing from the scope of the appended claims. Neither do I desire to limit this invention to certain uses1 as the uses to which it may be put are numerous;
lhat I claim herein as my invention is:
l. A flexible shaft, means for driving the iiexible shaft, a hollow handle portion, a secondary shaftvrotatably mounted inside of the said handle portion and projecting from the end of the latter,'means for casting the fieXible shaft,l when rotated, to drive the said secondary shaft, a wheel of the character set forth having a hollow recessed hub structure adapted to slip over the protruding end of the said secondary shaft, mechanism carried by the said secondary shaft and cooperating with the said recessed hub struc# ture when the said wheel is placed onto the said secondary shaft whereby the said wheel is retained on the said secondary shaft and is driven therewith when the latter is ro e tated, and spring-controlled manually-depressible mechanism extending` intothe outer end of the said secondary shaft and co-operatingl with the first said mechanism when depressed, for causing the first said mechanism to release the drive on the said wheel and simultaneously unlock the wheel retainer, while the said secondary shaft is rotating, to permit the said wheel to be removed from the said secondary shaft without rotating,
while the flexible shaft and the said secondary shaft continue to rotate.
2. A shaft means for drivin@` the said shaft, a wheel of the character set forth havber, 192e.
