MANICURING DEVICE Filed Oct 16. 1958 John N. Jones John H Pr/ce INVENTORS BY -MW MANICURING DEVICE John N. Jones, San Diego, and John H. Price, La Jolla, Calif.

Application October 16, 1958, Serial No. 767,617

1 Claim. (Cl. 132-736) This invention relates generally to new and useful improvements in manicuring devices and has for its primary object to provide, in a manner as hereinafter set forth, an electric power driven fingernail file which is self-contained.

Another important object of the present invention is to provide, in a self-contained power driven manicuring device of the aforementioned character comprising a hollow handle or housing enclosing a battery operated motor driving a reciprocating file, novel means for slidably mounting said file in said housing and operatively connecting said motor thereto.

Other objects of the invention are to provide a power operated fingernail file of the character set forth which will be comparatively simple in construction, strong, durable, compact, of light Weight, attractive in appearance and which may be manufactured at low cost.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof; where-in like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of a manicuring device constructed in accordance with the present invention;

Figure 2 is a detail view in perspective of the file;

Figure 3 is an enlarged view in vertical longitudinal section through the device, taken substantially on the line 3-3 of Figure 1;

Figure 4 is a view in transverse section, taken substantially on the line 4-4 of Figure 3;

Figure 5 is a cross-sectional view, taken substantially on the line 55 of Figure 3; and

Figure 6 is a view in horizontal section through the device, taken substantially on the line 6-6 of Figure 3.

Referring now to the drawing in detail, it will be seen that the embodiment of the invention which has been illustrated comprises an elongated hollow handle or housing 7 of suitable metal. The housing 7, which may also be of any desired dimensions is substantially oval in transverse section, as shown to advantage in Figure 4 of the drawing.

Mounted longitudinally in the lower front portion of the housing 7 and projecting through the forward end 8 thereof is a substantially C-shaped guide 9. Mounted for reciprocation in the guide 9 is a file 10 which projects forwardly from the housing 7. The rear or inner end portion of the file 10 has formed therein a transversely elongated opening 11.

Mounted vertically in the forward portion of the housing '7 is an electric motor 12. The motor 12 is secured at 13 on one of the side walls of the housing 7. The shaft ited States Patent 0 14 of the motor 12 has fixed thereon an eccentric 15 iwhich is engaged in the opening 11 for actuating the The rear portion of the housing 7 is internally enlarged as at 16 to provide a shoulder 17. Removably mounted in the portion 16 of the housing 7 is a case 18 of suitable insulating material. The case 18 is for the reception of a pair of batteries 19. The case 18 abuts the shoulder 17. A removable cap 29 of insulating material closes the rear end of the housing 7 and the case 18. Suitable fasteners 21 secure the cap 20 in position on the case 7. Mounted on the cap 20 is a resilient conductor strip 22 which electrically connects the batteries 19. At its forward end, one of the batteries 19 is electrically connected to the case 7 at 23. The corresponding end of the other battery 19 is electrically connected to a resilient contact or finger 24 which projects forwardly from the case 18 for engagement with a fixed contact 25 on the motor 12, A switch button 26 is slidably mounted in the housing 7 and engaged with the contact or finger 24 for engaging the same with the contact 25.

It is thought that the operation of the device will be readily apparent from a consideration of the foregoing. Briefly, to energize the electric motor 12, the resilient contact 24- is engaged with the contact 25 through the medium of the push-button 26. The button 26 may be conveniently operated with the thumb of the hand which grips the handle or housing 7. With the motor 12 operating the eccentric 15 reciprocates the file 10 in the guide 9 in an obvious manner. Access may be readily had to the case 18 by removing the cap 20. Then, access may be had, if desired, to the motor 12 in the forward portion of the housing 17 by removing the case 18.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

A manicuring device comprising an elongated housing providing a handle, a file slidably mounted in the forward portion of the housing and projecting forwardly therefrom, said file having an opening in its rear end portion, an electric motor, including a rotatable shaft, mounted in the housing, an eccentric fixed on said shaft and engaged in the opening for operatively connecting the motor to the file, said housing including an internally enlarged rear portion providing a shoulder at an intermediate point, an electric power unit for the motor removably mounted in the housing, said unit including a case slidably inserted in said enlarged rear portion of said housing in abutting engagement with the shoulder, batteries removably mounted in said case, means electrically connecting the batteries to the motor for energizing same, and common means closing the rear end of the housing and the case and securing said case in position in said housing in engagement with the shoulder.
