MANIGURIN G IMPLEMENT.
Application filed September 20, 1926. Serial No. 136,474.
This invention relates to manicuring devices, and more particularly to a power driven instrument of this class, and its principal objects are to provide a manicuring machine or implement that is especially suitable for use in public parlors, where speed, as well as neatness and accuracy, is essentlal; to PI'OVldQ a device of the foregoing character that greatly expedites the operation of 1 trimmin and polishing the nails; that protects the gers that are being manicured from injury; that insures neat and even trimming of the nails and that is very convenient of use.
The complete machine involves a stand, a motor supported by the stand for universal .movement with respect thereto, a flexible shaft leading from the motor, and a, manicuring instrument in the nature of a rotary tool that is carried by the end of the flexible shaft. A further object of the invention is the production of a machine of the foregoing nature that is neat and attractive of appear ance and is very compact so that'it mayoccupy a position on the average small manicuring stand and not be in the way of the opera tor or patron and leave ample room for the tray, basin, etc. I
These and other objects appearing hereinafter are attained in the embodiment of the invention illustrated in the accompanying drawings wherein Fig. 1 is an elevational view of the manicuring machine; Fig. 2 is an enlarged longitudinal section through the manicuring instrument; Fig. 3 is a fragmentary elevational view of the instrument. as though taken from the underside of Fig. 2; and Fig. 4 is a front view of the instrument? I Describing the parts by reference characters 1 denotes a base of wood or other suitable material upon which is mounted a metal, boxlike casing 2 from the rear side of which rises an upwardly and forwardly curved bracket 3 that terminatesin a boss 4 having bore.
with an annular a vertical Within this bore is journa ed a pin 5 having a head 6 whose underside is provided '00've for the accommodation of balls 7 t at travel on a hardened washer 8 that is applied to the upper end of theboss4.: I I
A yoke 10 is suitably secured to the lower end of the pin 5, and plivotally supported by and between the brane es of the yo e 10 is a motor 11 of suitable construction to the driving shaft of which is fastened one end of a flexible shaft 12 that is housed within a' sheath 13. The driving shaft of the motor and its connection with the flexible shaft 12 are not illustrated,as these features are in accordance with common practice.
To the end of the sheath 13 opposite the motor 11 is attached a ferrule 14 which has a threaded extension 15 adapted to be screwed into one end of an internally threaded fitting 16. The opposite end of said fitting receives the reduced, externally threaded end of a stock 17 that is knurled throughout its body portion to provide a suitable grip 18. The stock 17 has a bore 20 which is reduced in diameter adjacent itsinner end and is counterbored at its outer end to provide a shoulder 22. The forward end of the stock is enlarged to provide a crown 23 that is recessed in its front face as shown at 24.. 4
J ournaled within the bore of the stock 17 is a mandrel 25 the bod portion of which has a running fit within the larger section of the bore 20 while the rear end of the mandrel is of a diameter to have'a similar fit Within the reduced corresponding end of the bore, and
the for-ward end of the mandrel is enlarged to provide a head 26 that occupies the counterbored portion of'the bore. Interposed between the rear side of the head 26 and the shoulder 22 is a washer'27 of suitable material. 'The mandrel is held rearwardly within the bore with thehead 26 en agement with 26 is clamped a grinding disk or element 32 of suitablecharacter. This disk'may be constructed of abrasive material of a proved nature. vThe screw 31-.is shown as hol ow and internally threaded'for the rece tion of the threaded shank of a spindle 33 which carries, at it's forward end, a olishing head 34. Proj'ectingfrom one side of the crown 23 for- 'wardly a suitable distance beyond the front face of the guard 35.- tant part of the invention as it makes grinding disk or element 32 is a his guard constitutes an impor ssible the use of a power driven grinding or a rasive nail trimmer without the slightest danger of injury to the fingers operated upon.
In the use of the device, current is turned into themotor which drives the grinding element or disk 32 through the intervention of the flexible shaft 12 and the mandrel 25. The operator holds the instrument by the grip portion 18 of the stock 17 and the guard 35 is inserted beneath the nail that is to be trimmed in the manner illustrated in Fig. 2, where the end of the finger is shown in dot-and-dash lines at A. By drawing the instrument across the finger with much the same movement as is used when cleaning the nail, the grinding element is caused to trim the end of the nail from one side to the other, the guard 35 preventing the grinding element from engaging the fleshy portion of the finger beneath the nail or about the side edges thereof and at the same time prevents the nail from being trimmed too close. After the nail has been trimmed it may be polished by the polishing head 34 to which may be applied suitable polishing paste and powder such as are ordinarily used for the purpose.
The casing 2 contains a drawer 38 for the accommodation of various manicuring appurtenances.
Having thus described my invention, what I claim is:
1. A power driven manicuring instrument comprising a stock having a longitudinal bore, a mandrel journaied within said bore, a grinding disk secured to one end of the mandrel, the stock having a crown portion which surrounds the disk, and a guard projecting from one edge of the crown portion beyond the nail engaging surface of the disk and designed to project between the underside of the nail and the adjacent portion of the finger.
2. A power driven manicuring instrument comprising a stock having a longitudinal bore that is counterbored at one end to provide a shoulder, a mandrel journaled within said bore and having a head occupying the counterbored portion of the bore, a grinding disk applied to the face of said head, the stock terminating at one end in a crown which surrounds the periphery of the grinding disk, and a guard projecting from one side of the crown beyond the nail engaging surface of the disk and designed to project between the underside of the nail and the adjacent portion of the finger.
3. A power driven manicuring instrument comprising a stock, a mandrel rotatably supported thereby, an abrasive member carrie by the mandrel and adapted for operation up- I on the edge of a nail, a polishing head carried by the mandrel beyond said abrasive member,
