It is'also an object of thisinvention to provide a manicuring machine in which a plurality of rotatable tools may be used, said tools being easily and "quickly interchangeable forperforming the'various operations toolfor use in other of Other and further important objects of this'invention will beapparent from the'disclosures in'the accompanying drawing and the following specification.

The invention (in a preferred form) is illustrated on the drawing and hereinafter more fully described. d

On the drawing:

In the illustrated embodiment of this in- I vention, there is shown a casing formed of a 0 top portion 1 and a bottom portion 2 which are held together'in operative relation by bolts 3 and 4. The top and bottom portions of this casing are'formed with depressions 5 and 6 respectively, which are in confronting relationship and form an enlarged section in the container for receiving the marginal portions of an energizing coil 7 The energizing coil is disposedaround one leg of a U-shaped core 8 and held against a 17 of the screw head bearing against the spring 14. It is therefore obvious that by tightening or loosening the screw 15 the pressure on thespring 14 may be varied to regulate the vibration of'the armature 1.3.

A pole piece 18 is secured to the armature in position to be influenced by the magnetizing forces set up in the core 8 when the coil 7 is energized. The free end of the armature 13 is bent at anangleto form a portion 19'which projects through an aperture 20 of the casing 2 and carries at its outer end a rubber tip 21 which serves as a cuticle set orpusher, when the .arm 13 is vibrated. A rubber stopmember 22 which is positioned near the free end of the armature 13, serves to cushion said armature when moved, outwardly bythe spring-14, and also prevents it from striking the casing'2.

- Adouble-pawl ratchet mechanism is. provided fortransforming the vibratory motion of 'the'armature 13 into'a rotary motion, stub shaft 23 is-secured to an upwardlyoflset portion 24 at one end of. the plate 9, and projects outwardly through an aperture 25 in the top portionl of the casing. tubular sleeve 26 havingla ratchet wheel 27 secured to oneend thereof is. rotatably mounted upon the stub shaft .23, the ratchet wheel being positioned adjacent the inner end of said shaft and the outer end of. the sleeve projecting to the outside of the casing. The sleeve I 26' isprovided with apair of parallel apertures f28 which' penetrate the inner wall of the sleeve and communicate with a'circumfer'ential groove 29 formed in the stub shaft 23. -A U-shaped pin having each leg thereof disposed in one of said apertures prevents the removal of the ratchet wheel'and sleeve fromthe: stub shaft, but permits the same to rotate freely thereon. Intermittent rotary motion is imparted to the ratchet wheel 27 by'mean's of a pair ofpawls 30 and 31 which are .pivotally mounted between the arms of "a yoke member 32 carried by the armature 13,

saidpawls being secured by a U-shaped pin 33 each leg. of which extends through the yoke arm and flange 33 formed at the end 'of'each pawl, A spring 34 which is also secured to the yoke member is provided'with curved ends which bear against the pawls 30. and 31 and hold the free ends thereof in engagement with the toothed periphery of the ratchet wheel 27.

The free end of the pawl 30 terminates in a hook 35 which will engage the toothed periphery of the ratchet wheel and pullthe same in a clockwise direction when the armature 13 moves away from the ratchet wheel.

The pawl 31 is formed so that the free end thereof engages the toothed periphery of the ratchet wheel 27' and pushes it in a clock' wise direction when the armature moves toward the ratchet wheel. Since each pawl is designed so as to slide overthe teeth when the other pawl is functioning to advance said ratchet wheel, .it is apparent that, as long as the armature 13 vibrates back and forth, an'intermittent rotarymotion will be imparted to the ratchet wheel. I

A variety of interchangeable rotary tools is provided for performing the various operations required in manicuring. Thesev tools may be providedwith filing surfaces, buffing surfaces, and the like as required; means being provided for quickly and easily attach ing any desired tool." To illustrate the con struction and means for attaching the tools,

a rotary file 36-is shown; The file 36 comprises ;'a disc portion 3'? having cutting grooves 1n the outer surface thereof, and

terminating'in a circumferential flange 38 which-is similarly' groovedupon its outer surface, The central portion of the disc ter- Inmates in a sleeve 39. which fits coaxially over the sleeve 26 and is held against 'longi- .tudinal movement by an inwardly project- 1ng n1b 40. which engages a circumferential groove 41 in the sleeve 26 The sleeve 39 is also vprovided with a longitudinally extending slot 41 at one end for receiving a pin 42 carried by the'ratchet wheel 27, thereby causing, the sleeve 39 and ratchet wheel to rotate as a unit. The rotary tool is prevented accidentally disengaged from thefsleeve 26 by means of a guard plate 42 which is pivotally .secured by a from becoming screw 43 to the casing 1'. This guard plate is provlded with a depression 44 for receiving the end offlthe stub shaft'23, thereby latchmg the guard i'n'position over the rotary tool. The free end ofthe' guard plate 42 projects past the edge of the rotary tool and terminates 1n a curved edge 45, which serves as an upper finger rest. A lower nail rest is formed by a lug 46 on the top portion 1 of the casing, said lug being positioned on the opposite side of the'rotary tool from the upper finger rest. When it is desired to remove a rotary tool from the device, the guard 42 is swung to the position shown in dotted lines in Figure'1. 1

The casingis narrowed at one end so that the rotary tool 36 will overhang the edge 47 the casing thereby in no way interfering with the application of the rotary tool in the manicuring operation.

A make and break device comprising an arm 48 and an arm 49 is secured to one of the lateral projections ll by means of a screw 50 which threadedly engages a platesuitably 51. Separating blocks 52 are placed'for insulating the arms 48 and '49.

The'arm 48 carries a contact point 53 and r thearm 49 a contact point 54, said points rection, the pawl sliding over the teeth of norm-ally being in *"engagement.. The arma-' ture;13 carries a, pair. of's'paced arms of insulating material which 1' are disposed onv either. side j'oftheprojecting end of the armv '49 of the make and break device to-open or providedwithythree'prongs A, B, and C which are formed so as to make contact with mating members in the insertable plug. When the two-point plug is disposed in the socket 56 so as to make contact with the prongs A and Qelectrical connection is established directly to the coil 7 7 through conductors'58 and This connection should only be used'when operating the device from an alternating current supply.

When it is desiredto operate the device from adirect current'su-pply, the plug is inserted in the socket 56 so as to make contactwith the prongs A and B, which establishes one connection directly to the coil 7 through conductor 59. The other side of the circuit whereupon the coil 7 is alternately energized and deenergized. When the coil is energized, the armature 13 will be attracted and moved downwardly against the pressure of the spring 14. This downward motion of the .rarmature 13 will cause the pawl 31 to advance the ratchet wheel 27 in a clockwise dithe ratchet wheel. Upon the deenergizing of coil 7, the spring 1% will cause-the armature 13 to move in the opposite direction. This movement will cause the pawl 30 to advance the sprocket wheel 27 in a clockwise direction, and at the same time the pawl 31 will slide overthe teeth of the sprocket wheel and assume a position for its next operation in advancing the sprocket wheel as before. So long as the armature 13 continues to vibrate, the sprocket wheel will rotate and drive the rotary tool connected thereto. The cuticle pusher 21 may also be used to stop the rotation of the rotary tool. Since the cuticle pusher is in direct connection with the armature 13, it is evident that the advancement of the ratchet wheel may be prevented by the V operator of the device pushing against the cuticle pusher so that the armature will not be able to vibrate. This is an advantage in that the operation of the rotary tool may be temporarily stopped without electrically disconnecting the device.

The operation of the device from a direct current supply will be the same as when operating from an alternating current source, except that the plug is inserted in the socket so as to make connection with the prongs A and C. This connection inserts the make and break device in one side of the circuit to the coil, so that, when the coil is energized, the

armature 13 will be attracted as before and move against the resistance of the spring 14.

This movement of the armature will cause the to the coil, which now becomes deencrgized.

The coil being deenergized, the armature will be moved upwardly by the spring 14, contact 54 will engage contact 53 and reestablish the circuit through the coil, which being again energized will attract the armature 13 as before. This operation will continue so long as direct current is supplied to the device, or until the device is stopped by the operators pressing upon the cuticle set 21-. The operation of the ratchet mechanism will be the same as whenoperating from an alternating current.

This invention, therefore, provides a power manicuring device which is compact in construction, easy to use, which may be operated either from direct or alternating current, and which uses a rotary tool, said tool being easily and quickly detached from the device for replacing with a tool for performing some other operation incident to manicuring.
