menses.

Application filed. February 10,1922.

To all whom it may concern:

Be it known that we, MILTON H. BURK- and Eorrrr MAY Gunman, citizens ofthe' ing instruments of this character, such as the ordinary finger nail buffer.

As generally stated, the object of the invent-ion is to provide a buffing tool which can be held in the hand and caused to operate without the necessity of any back and forth motion of the hand, the, under portion of the tool or instrument being adapted to reciprocate relatively to the handle or upper portion of the instrument, and means being pro *ided within the instrument for rapidly vibrating said reciprocating por tion, on the finger nail, or on the object to be smoothed or polished.

It is also an object to provide certain details and features of construction tending to increase the general. efficiency and the desirability of a vibrating buffer of. this particular character, and whereby the tool or instrument may be operated electrically, by an electric buzzer or other suitable means, as will. hereinafter more fully appear.

To these and other useful ends the invention consists in matters hereinafter set forth and claimed and shown in the accompanying (rawings in which- Figure 1 is a side elevation of a manicuring instrument in the form of a finger nail buffer embodying the principles of the invention.

Figure 2 is a view looking down on said instrument. a

Figure 3 is an end view thereof.

Figure 4 is plan view of one portion of the instrument.

Figure 5 is a cross section on line 5 in Figure 2.

Figure 6 shows some of the small parts or details of the construction.

As thus illustrated, the invention comprises a top plate 1 having a handle 2 rigid therewith. The under side of this top plate is preferably provided with longitudinal grooves 8, two at one end and one at the other, formed in any suitable or desired Specification of Letters Patent. P tta a Aug, 8, 1922,

manner. The bottom plate l is formed with longitudinally disposed knife edges 5 to slide longitudinally in said grooves, the buffer proper 6 being suitably attached to or carriedby this bottom plate, and being covered with suitable material for polishing the nails. Said handle 2 is hollow and forms a housing for the electro-magnetic mechanism employed to vibrate the buffer. Said mechanism comprises a magnet 7 for operating the vibratory armature 8'into and. out of engagement with the screw ,9, said armature being subject to the action of coil spring 10, whereby the magnet draws the armature out of engagement with the contact screw 9, while said spring then draws the armature back into engagement with said screw. In this way a buzzer is formed, it being understood that the current, from any suitable source, passes through the coils or convolution of the electro-magnet 7, then through the armature 8, then to the contact 9, and then back to'the source of current, whereby the circuit is opened. when the armature is pulled over by the magnet, and. is again closed when the armature is retracted or returned to normal position against the screw 9 by the tension of the said spring. It will be 11.11 derstood, of course, that suitable insulation is employed wherever necessary to ensure against short eircuiting of the current, and to ensure the desired operation of the mechopened and closed in the manner explained.

.The lower end portion of the armature 8 passesthrough a slot 11 in the bottom plate 4: and down into-the buffer where it is pivotally connected. by a single screwlQ,

\vhereby said armature supports the buffer and its plate at in sliding contact with the under surface of the top plate 1, in a manner that will be readily understood. The grooves 3 and the edges 5 form guides to keep the buffer in position while rapidly reciprocating endwise in the desired manner. The plates can be made of sheet metal, such as aluminum or any other suitable metal, and the entire operating mechanism is preferably mounted on a supplemental frame 13 which is inserted in the hollow handle 2 and which isheld in place therein by a single screw 14 inserted through the side of said handle. By removing this screw 14:, the entire mechanism and the bottom plate 4 can be removed downwardly from the handle and the upper plate, and by removing the screw 12 the. electro-magnet buzzer mechanism can be disconnected from the buffer. As shown, the armature 8 is in the nature of a flat spring having its lower portion twisted one quarter around for attaehment to the buffer, but it will be under- I stood that either a spring flexible armature or a pivoted armature can be employed for this purpose, for the tension of the spring 10 can be regulated by the screw adjusting means 15 in a manner that will be readily understood, thus ensuring the desired make and break action in the circuit of the magnet, whereby the latter is alternately energized and de-energized in the ordinary and well known manner. It will be understood, of course, that the circuit wires may enter the handle or any other portion of the structre, in any suitable or desired manner. For example, in use, the circuit Wires may be embodied in an ordinary flexible cord which leads to the handle and which has its other end provided with a plug or other device for connection with a socket or other terminal connected to the source of current. Means will be provided, of course, for controlling the current, so that the operation of the instrument can be started and stopped at will. When the instrument or tool is held in the hand, and the current is turned on, the mechanism then causes the bufier to reciprocate rapidly, whereby the desired polishing of the nails is accomplished without the necessity of moving the arm back and forth. In other words, the hand grasping the handle is held stationary, and the mechanism reciprocates the buffer in a rapid manner to produce the desired result, thus relieving the operator oruser of the necessity of moving the arm back and forth in order to polish the nails. It will be understood, of course, that the construction shown anddescribed is merely illustrative of the invention, and that the invention is not limited to the exact construction shown and described, inasmuch as the broad idea of automatically reciprocating the buffer can be accomplished in any suitable or desired manner,-very obviously, without departing from, the spirit of the invention.

What we claim as our invention is: 1. In a manicuring instrument having a handle for the manipulation thereof, a finger nail buffer and means therein for rapidly vibrating the under portion thereof on the finger nail and means to detach said under portion to afford access to said means within said handle.

2. A manieuring instrument as specified in claim 1, the said vibrating means comprising an electro magnet and an armature therefor, and means to removably support the magnet and its armature as a unit in operative position in said handle.

3. A manicuring instrument as specified in claim 1, the'top thereof having said handle in which said vibrating means are entirely enclosed, the under portion of the instrument being supported entirely by said means and mounted to reciprocate relatively to said handle.

1-. A manicuring instrument as specified in claim 1, the said vibrating means comprising an electric buzzer in the upper portion of the instrument, said under. portion being supported entirely by said buzzer to reciprocate relatively to said upper portionby straight sliding motion thereon.

5. In a buiiing tool, the combination of a reciprocating portion for frictional engagement with the object to be smoothed by the bufiing action, a handle, and means in said handle to both support and rapidly vibrate said reciprocating portion relatively to said handle.

6. A structure as specified in claim 5, said vibrating means being electrically operated.

7. A buffing or polishing device adapted for use as a manicuring instrument, comprising a top plate having a hollow hand e, on the upper surface thereof, an elongated buffer slidable endwise back and forth on the bottom of said plate, provided with a surface covering adapted for polishing the finger nails, the buffer being rounded and shaped substantially like that. of an ordinary manicuring instrument, and means enclosed the necessit of reciurocatin the bufferi is manually during the manicu'ring of the nails.

in claim 7, said operating means comprising 8. A manicuring instrument as specified an clectromagnet armature supported at its upper end in said handle and extending downward into the buffer to both support and operate said reciprocating buffer in the 1 desired manner.

9. A manicuringinstrument as'specilied in claim 7, said reciprocating buiferhaving a edges, substantially as shown and described.

10. A in claim 7, said operating means serving to entirely support said reciprocating buffer against the bottom of said top plate.
