MANICURING DEVICE Original Filed Nov. 6, 1929 IZTLTEW H1255 HEaZ-Zagher Patented June 27, 1933 UNITED STATES PATENT OFFICE MILES I-I. GALLAGHER, OF CHICAGO, ILLINOIS MANICURING DEVICE Application filed. November 6, 1929,=Seria1 No. 405,222. Renewed August 25, 1932.

My invention relatesin general to manicuring devices, and the object of the invention, briefly stated, is the production of an improved device of this character which is .5. rapid in operation, safe to use, and inexpensive to manufacture.

The construction of the device and its advantages will be pointed out hereinafter with reference to the accompanying drawing, in 1 which Fig. 1- is a side view of the device assembled on an ordinary dentists hand piece or drill chuck; I

Fig. 2 is an end view of the same;

Fig. 3 is a bottom View of the device, detached from the hand piece; while Fig. 1 is a perspective view illustrating how the device is used.

Referring to the drawing, the reference character 2 indicates a guard of the form shown, made preferably of sheet metal and nickel plated or otherwise made proof against rust, as are the other parts of the de-v vice. The guard 2 is attached to a rod 3 of heavy wire which has a number of laterally extending coils 4, which slip tightly over the hand piece 6, thereby supporting the guard in position.

The reference character 5 indicates a shaft or mandrel similar to those used by dentists for driving grinding tools. It extends through an opening in the guard 2. Inside the guard, the buffer wheel 7 and the steel grinding disc 8 are secured to the mandrel in a manner similar to the way in which dentists grinding tools are secured, being clamped between the cone shaped end 9 of the mandrel and the head of screw 10. The

screw 10 engages a threaded hole in the end 7 seen in 2. ably made with different curvations to adapt the device for use on both large and small finger nails. spaced farther from the center than the other so as to. utilize a different portion of .the grinding surface of the disc 8. The reference character 13 indicates a projec'tion at the end of the guard, which may be formed by an upsetting operation.- This projection is suitable foruse as a means of pressing back the cuticle. V The operation of the device will, no doubt, be sufliciently apparent from What has been said, but may be briefly explained nevertheless. The operator will hold the device in one hand by means of the hand piece and will grasp onefinger of the customer in the other hand. The Imotor may then be started by means of the usual foot pedal, thus rotating the buffer wheel and grinding disc. The device is then brought into position against the end of'the finger, the fingernail projecting These openings are prefer- One opening is also preferably through one of the openings 11 or 12 in contact withthe grinding disc 8, as shown clearly in Fig. 4. Then by suitable manipulation of the devicethe finger nail is rapidly shaped up as desired. After a nail has been trimmed in the proper manner it may be finished by polishing with the buffer.

It will be seen that I have produced a highly efficient manicuring device, which has numerous advantages. The abrasive surface of the disc 8 outs very fast, and thus a finger nail may be trimmed very much more rapidly than in the case when the ordinary file is used. At the same time the rapidly rotating disc, which might be more or less dangerous otherwise, is rendered entirely safe by the guard in which it is substantially It will be observed also that the enclosed. combination of the grinding'or cutting ele ment with the bufiing'or polishing element makes a very' eflicient device, combining in one too]. all the principal functions which a device of this character is required to perform. From the mechanical standpoint'also the combination is very effective. The buffer wheel, being qu te substantial, serves as a support for the rather flexible grlnding dlsc and renders it possible. to use the latter as pointed out, while the 'disc' does duty as a washer under the head of screw 10 for securing the buffer wheel to the mandrel, thus imaking for a maximum simplicity.

It will be understood that although. I have shown my improved m'anicuring device in the form of an attachment for use in connecable to provide a simpler form of hand piece to which the guard may be permanently attached. with the mandrel more or less permanently connected with the flexible shaft. This eliminates-the expensive drill chuck which in fact is unnecessary when the device is used solely for manicuring purposes.

Having described my invention, what I consider to be new and desire to have proin the appended claims I What is claimed is: V I

1. A manicuring device comprising a hand piece, a buffer wheel and a grinding disc rotated by the shaft terminating in said handy-piece, said buffer wheel servingias a support toprevent lateral bending of said disc, and a guard substantially enclosing said wheel anddiscbut having openings through which the same may be appliedto a finger nail. v

I 2. In a manicuring device, a dischaving a grinding surface on one side thereof, a guard tected by Letters Patent will be pointed out I substantially enclosing the disc andhaving an opening through which a finger nailmay be brought in contact with said disc, and means for continuously rotating said disc comprising a shaft extending outside said guard.

3. In a manicuring device, a rotatable shaft, a bufier wheel secured to said shaft, a grinding, disc secured to said shaftagainst said wheel, and a guard enclosing said wheel and disc, there being an opening insaid guard to exposethe vbuiiing'surface of said wheel and a second opening to expose the grinding surface of said disc.

4. In a manicuring device, a compound grinding-and buffing-wheel having a grinding surface on one side and a buffing surface around the periphery,together witha guard havingan opening through which a finger nail may be trimmed bythe grindingsurface and another opening through which a trimmed nail may be polished by the buffing surface.

5. In a manicuring device, a hand piece, a rotatable shaft projecting from said hand piece, an abrasive wheel secured to the end piece, a disc secured to the end of said shaft,

said disc having abrasive material forming a flat cutting surface on the side thereof remote from said hand piece, a housing substantially enclosing said disc, supporting means connecting said housing with said hand piece, and an opening in the end of said housing through which a finger nail may be brought intoworking engagement with said cutting surface. V

In witness whereof, I hereunto subscribe my name this 4th day of November, A. D.

MILES r1. GALLAGHER.
