Referring to the drawings, I have shown at I a housing preferably made of ornamental appearance and enameled in an aesthetically beautiful color and containing (not illustrated) v an electric motor.

Circuit wires 2 terminating in aplug 3 are connected to the `motor within the housing I for driving it in the well known man- Der A switch of theturnbler type l controls the part of my invention and have not been fully Y The parts thus far described form no essential illustrated inasmuch as electric motor driven cables of this character are well known in the art.

The cable housing 5 as shown in Fig. 4 and indicated in Fig. 2, is connected to a tool handle The cable 'I is connected to a rotary part within the handle to be described. Upon the top of the housing I is mounted a post 9 carrying on its upper end a U-shaped handle support i9, the legs l! and I2 of the U being bent into C-forrn in generally parallel planes and with the open side of the C of the two legs facing in opposite directions. When the cable housing and the cable 'l therewithin are bent or wound in the generally clockwise direction as viewed in Fig. 2 to dispose them around and upon the housing I, the tool handle S may be lodged in the C-form legs II and the resilient tendency of the housing and cable to unwind will cause the handle to be gripped in the C-form legs II and I 2 to secure and support it upon the housing I, as illustrated in Figs. l and 2.

Furthermore, the closed end of the U-form support I9, being spaced by the post S from` the top of the housing I, provides a handle under which the fingers of the hand may be inserted for lifting and transporting the entire motor unit from place to place.

Referring to Fig. 4, the tool handle 8 oomprises an elongated cylindrical body portion I3 to the inner end of which is secured the cable housing 5, the preferred construction comprising a sleeve Ill into which the end of the cable housing is telescoped and to which it is permanently secured, the sleeve I4 having a threaded portion of reduced diameter I5 threaded into the end of the handle body portion I3, a shoulder I5 abutting upon the end of the handle portion. Into the opposite end or outer end of the body portion of the handle, a chuck housing II generally of elongated cup form is screwed, by external threads i3 on the chuck housing and corresponding inner threads on the body portion of the handle, and the inner end of the chuck housing abut upon a shoulder of the body portion, as for example at I9, to rigidly secure these parts together.

The outer end or cup bottom of the cup-form chuck housing is provided with a perforation or aperture 2o through which the shank portions of tools may be inserted in a manner and for a purpose to be described.

The end of the chuck housing I'I is preferably formed cylindrical as at 2I and provided with a shoulder 22.

Within the tool handle 8 is a rotatably mounted shaft 23 the outer end of which terminates, as at 24, adjacent the end of the chuck housing Il and is longitudinally bored as at 24 in alignment with the aperture 2U and longitudinally slotted as at 25 to provide a plurality of resilient chuck jaws 26-26 for gripping a tool shank to be described, and the outer surfaces of the jaws are tapered, aring outwardly toward the outer end as shown at 2l.` A chuck jaw operating sleeve 28 slidably mounted on the shaft 23 engages at its outer end portion as at 29 the tapering portion 'of the jaws. By this construction when the sleeve 28 is moved outwardly, the jaws are moved radially inwardly to grip a tool shank therewithin; and when the sleeve is moved in the opposite direction the resilience of the jaws moves them outwardly to release the tool shank.

The movement to engage the tool shank is effected by a compression spring 3l) surrounding a portion of the shaft 23, abutting at its inner end upon a flange 3I of a sleeve 32 telescoped over the shaft and preferably secured rigidly thereto by a pin 33 projected through the sleeve Si. and the shaft; and the other end of the spring abutting upon the inner end 34 of the chuck operating sleeve 28; and to move the sleeve 28 in the chuck-releasing direction, the following construction is provided.

An external sleeve 35 is mounted to slide on the body portion I3 and chuck housing I1, being telescoped thereover, and has threaded therein a plurality such as three radially extending screws 36--36, the screws having smooth unthreaded cylindrical inner end portions 31 projecting through longitudinally extending slots 38 in the tubular wall ofthe chuck housing I'I and projecting at their inner ends into an annular groove 38 in the outer surface of the sleeve 28.

By slidingly moving the sleeve 355 inwardly, the ends 3T of the screws 35 engage the side of the groove 38 and retract the sleeve 2S against the compression of the spring 30 to release the chuck jaws and upon releasing the sleeve 35, it, together with the sleeve 25, are returned by the spring 30 to the chuck gripping position illustrated.

The flange 3| prevents axial movement of the shaft 23 inwardly and movement of the shaft outwardly is prevented or stopped by a flange 3S on a connecting element 4I) threaded upon a reduced end il! of the shaft. The .flanges 3l and 353 may abut upon corresponding opposite shoulders I9 and 42 formed in the body portion i3 of the tool handle 8.

The connecting element 4!! comprises a generally cylindrical portion 42 into which the threaded portion 4I of the shaft is screwed at one end and at the opposite end is bored out as at 43 and has rigidly secured therein the end of the driving cable 1, as shown in Fig. 4, the outer diameter of the element 4B being sufficiently small to rotate freely in the bushings I4--I5.

By the construction above described it will now be clear that the tool handle may be grasped by an operator by the body portion I3 and chuck housing I1 and sleeve 35, these portions remaining stationary and not rotating; and that upon application of power to the motor above referred to to rotate the cable 1. th-e shaft 23 together with the chuck jaws 2G thereof will be rotated in the handle and a tool whose shank is projected through the aperture 2B and gripped by the chuck jaws and projecting outwardly from the end of the handle will likewise be rotated. Furthermore, the tool shank may be inserted in chuck jaws or removed therefrom while the chuck is being rotated, that is to say, without stopping the motor.

Tools operable by the chuck handle just described wlll now be considered in connection with various manicuring operations which may be performed.

A nail polishing operation may be performed by the tool illustrated in Fig. 9, the tool being illustrated in connection with a portion of the chuck handle above described. The tool comprises a holder 45 having a cylindrical rsleeve portion 4B adapted to slide over thev outer end portion 2I of the tool handle above described. Outwardly the holder 45 has a cylindrical bore 41 therethrough in which is rotatably mounted a tool shaft 48 having a collar 49, preferably formed integrally therewith, engageable with an interior shoulder 5I! of the holder to prevent axial movement of the shaft in the holder in one direction,`the shaft 48 beyond the shoulder GS being reduced in diameter to provide a shank 5I adapted to be inserted through the aperture 2n and within the chuck jaws 26 above described and to be gripped by the same.

The outer end of the shaft 4B has a reduced the screw being` secured to the outer end' 'of the threaded portion 52 of the shaft, for example by a nut portionY 56 of the screw press-fittedinto a recess in the end of the portion 52 A polisher or buffer 51 having an axial bore 58 therethrough is mounted in the receptacle 54 and is of asize to substantially fitl the inner wall thereof anclwith the screw 55 screwed intovr the bore 58. y The buifer 51' is made from suitable bufling material such as felt or like material.

Inoperation ofthe tool of Fig. 9, the motor turns the chuck jaws'in the manner above described and thereby'turnsy the shank `5| and shaft 48 and the bulerV 51 at relatively high" Velocity. The end portion 5901' side Vportion 60 of the buffer 51 may be applied to the finger nail to polish the same with arbufling action. In presenting the buffer to the nger nail, kthehand of the operatormay embrace the handle above described and may support -the `buffer by gripping the holder 45 within which theshaft 48 rotates as will now be understood. yThe holder 45 is maintained in assembled relation with lthe shaft 48 partly by engagement of the collar'49l with the shoulder 50 as described and also by the engagement of the ,outer end 6| of theholder with a shoulder portion 52 of the receptacler 54,. As will be apparent, the buifer51 may be readily removed and renewed or replaced. `To secure the buing tool to the handle, it is only necessary to slide the sleeve 35 inwardly, insert the rshankV 5| in the chuck and the sleevej portion 46 of the holder over the end of the tool and release the sleeve 35 as will be understood froin'th'e foregoing description.

Due to the circular shape of the end of the cylindrical buffer 51, allportions of the nail to the extremeedges thereof may be reached to be buied and polished and the buffer may rhave applied thereto polishing material as will be understoodrby those skilled in this art. ,The ease of mountinga buffer' 51vin the tool and of re'- moving Ait therefrom and the relatively small expense' of the buffer due to the simplicity of its construction, permits the use of a fresh buifer for each manicuring-operation for sanitary vand like purposes. l f

In Figs..10 and 1l is illustrated a nail cleaning tool and a method of operation thereof. The tool as shown in Fig. l0 comprises a holder'63 gener-ally similarV to the holder 45 abovende-l scribed having an axial bore 64 in whichV is rotatably mounted 'a shaft B5 having a collar/66 abutting against an linternal shoulder 81 ofthe holder and an outer shoulder 68 abutting against the outer end of the holder. The shaft |55 is preferably formed from two pieces 69and`10 telescopically threaded together, a chuck jawengaging shank 1| extending inwardly from the pieceSS. Both pieces 69 and 'lunare axially bored as at 12 to receive the stem 'I3 of the nail clean-- ing tool, the inner end of the stem being threaded as at 14 into the shaft piece 89. f v

The outer end of the stem 13 has mounted thereon a plurality of bristles 15,`the outer ends of which are disposed in a plane 1B at right angles to the rotary axis; and inwardly of vtheir ends, the bristles 15 are disposed to define a frustrum of a cone, and inwardly, toward the .apex of the cone, the bristles are' 'clamped as at 11 be-Y tween a pair of frustoconical outer and'ihner sheet metal *stamping elements 1li-'and 19. 'Preferably the outer element 18 has a tubular extension 'surrounding the stern 13 and abuttingl 2 inwardly upon a shoulder 8|v thereof.- The stem;V

outwardly of the shoulder,- extends through the tubularlportion 80, and through a suitableperforation in the inner rclamping element '|22 v and is riveted over as at zexerting a clamping and supporting action on the bristles. 'f Y l.

Upon mo -ting the tool of Fig. l0 upon the handle by inserting the shank "1|fin the chuck:

jaws, the bristlesv15 may bev rapidlyy rotated and may be presented to the finger to ber cleaned by grasping thetool handle and the tool holder 63, the latter not rotating as will nowbe understood, and as illustrated in Fig. 1l. Thebristles may be presented .to thenails to clean any. desired portion thereof on the outer .or on the under-v side thereof and by virtueof disposing-the holder 63 adjacent therotating bristles, their position maybe delicately controlled l.to avoid directingv the bristles against .'ser'isitiv'e*portionsl 'of the flesh such as that under the nails, dr ,at the cuticle.:

A Inasmuch 'as the stem 13 is removable from the `tool together with `the-bristles thereon, the same may bereadily .disinfected if desired. i

In Figs. 6, 7, 8, 15'and`16 is illustr'atedlaltool for trimmingfth'e fingernails. r As shown'in Fig. '1, the tool comprisesa'holder comprising a sleeve portion 86 for telescop-ing over the end of the tool handle anda shank 81 to be Agripped by the chuck; l'A head 88 a cylindrical bearing stem portion 89 'telescoped' into a corresponding bore 90 vof the holder 85 and is rotatable therein. Y The head hasl a ange of iny creased diameter 9| outwardly 'thereon'in the outer end of which-isL formed an oblong recess 92. The peripheryofthe ange 9| -is'p'referably frusto-conical in form div/erging outwardly and is substantially surrounded by a `skirt193 on the holder 85, `internally frus'to-conical to'substantially t with small clearance the flange '3 I The edge 94 of 'the skirt projects beyond the outer end of the flangeSi. The shank 31 on theen'd opposite the chu'cking portion thereof is enlarged to provide a head 95 terminating outwardly"` in an enlarged flange 96. `A sandpaperor' Yemery` disc 91 having a perforationr 98 therein substantially the same size and shape as the ,head 95 isy disposed between the flange 9| and the flange 95.

The shank a1 may beY inserted into the chuck jawsv andv withl the end of thehandleas at 99 disposedadjacent the inner endof the head 89; Rotation of the shankfl will rotatablydrivethe head 9| and the disc 91.' The disc may be readilyr renewed byrernoving the shank from the chuck jaws as will `be understood from the foregoing description and from the drawings-v A Whenthe -tool as shown in Fig'. '7 is secured to the handle as described; the holder 85 may be graspedby the hand as illustratedin Fig".` 8 to effect delicatecontrol of the positionof the disc 91 and the disc may be presented to' the fingers to trim and shape the Vsame as desired. Thovery.

lappir'igskirt` 93 permitsit to restV against/the iiesh adjacent the nail edge so as to ,avoid any Vpossibility that the rotating. emery disc may contact with the flesh, and to further assist the operator in directing the movement and posi tion 'of the f Preferably a slot or recess |00 is provided in `the skirt 93 extending part way thereenound and on a portion whichv may be disposed remote from the finger being operated'upon to facilitate the removal, by centrifugal forceyof dust. and the particles of emery `which are freed from the nger nail and from the trimming disc during lthe operation thereof and to prevent the. same fromworking inwardly to the bearing surfaceS. l

In Figs. l2, 13 and 14 is shown a tool for treating the cuticle at the base of the finger nail by compressing or'compacting the sameqtoward the base of the nail. The tool comprises a holder |02 generally of sleeve form adapted 'to'be :telescoped over the end of the tool handle andlhaving screW-threadedly vtelesco'ped into its outer end a guide |03 tapering outwardly and having an axial lbore |05 therein. f The chuck jaw` engageable shank |06 is provided with a collar |01 disposed against the inner side of a flange |08 and forwardly ofthe collar projects through a perforation |09 in the flange and terminates in a threaded portion ||0.

Acam is rigidly threaded upon the threaded portion and isgenerally of hollow cylindrical form, the outer-end of which is provided with a camming surface H2. 1

A sleeve ||3 is disposed in the bore |05 above referred to and'on its inner end has an enlargement ||4 of hollow cylindrical form provided on its inner'end with a .cam surface l5. A pin I6 is projected vthrough the cam 4 and opposite ends are disposedin axially extending parallel slots l1 ln a tubular extension |8 of the head |03, and within which tubular extension the cams ||2 and H4 are disposed. A compression spring ||8' abuts at one end upon a shoulder 9 of thesleeve 3 and upon a shoulder |20 of the guide |03 whereby the sleeve I3 and its cam I |4 is resiliently thrust inwardly'to maintain the cam faces in engagement. f

In the outer end of the sleeve ||3, a tool tip |2| is telescopically inserted @terminating outwardly inga preferably wedge-shaped end |22.v The tip |2| may be formed from any suitable material but orangewood or the like is preferred.

By the foregoing construction as will nowr appear, when the shank 06 is gripped by the chuck and is rotated, rotating the cam'l I la', its cam face reacting on the cam face of the cam I I4 will transmit thereto a reciprocating movement, one complete reciprocation for each revolution, and giving to the tool tip at |22 a rapid reciprocatory movement. The holder |02 is. unmoved during this operation and the tool handle may be gripped by the operators hand, and with the holder |02 between his fingers ask illustrated in Fig. v13, and the tip |22 may lbe'applied to the cuticle at the base of the nails tocompressv and compact the same for the well known purposes. Y

The tool tip 2| may be readily removed for renewalfor sanitary purposes or the like.

As will now be apparent from the above description, I have provided by my invention, not only improved apparatus by which manicuring operations may be performed, but apparatusperforming these operations in an improved manner. The various tools are constructed to facilitate the performanceof the various operations by the manicurist, and the operations are performed without discomfort or danger to the fingers being manicured; and the tools for the variousopera` tions may be mountedin a common handlefor power 4drives by'simple movements or removed therefrom Without the necessity of acquiring skill; and the portions of the tools coming in contact with the fingersbeing operated upon may be renewed or disinfected for sanitary purposes or the like; and the apparatus is adapted foruse by a professional manicurist or by the user himself upon his own fingers. All of the necessary operations are performable by the apparatus above described and therefore a complete manicuring operation may be effected in the minimum of time.

VThe tool case of Fig. 3 preferably comprises a base |25 supporting a rotatable head |26 having spaced vertically disposed bores |21 therein in which the Shanks 5|, 1|, 8l and 06 of the several tools may be inserted vwhen not in use and from which they may easily be reached and removed for mounting in the tool handle 8. A cover |28 having a handle |29 is provided for the tool supporting base to cover the tools when not in use.

'I'hus by constructing the motor housing of Figs. 1 and 2 and the tool case of Fig. 3 tohave ornamental aesthetic appearance, the entire outt may be made aesthetically beautiful to harmonize with decorations of professional manicuring establishments or to suit the personal taste of individual purchasers and users for installation in the home.
