` ELECTRICAL SAFETY RAZOR.

Application led November 20, 1925. Serial No. 70,255.

This invention relates to razors, and more particularly to electrically operated razors of the Safety variety, and the primary ob- 'ect of the invention comprehends a means y which a reciprocal action is imparted to the cutting element ofthe razor by electrical energy, whereby to obtain a greater degree of cutting efficiency by effecting a mechanical lateral action aswell as the vertical action of the blade, by manual manipulation of the instrument over the surface of the skin.

The invention further provides a razor of such form and shape as to afford a convenient hand hold for efficient manipulation to obtain effective results, as well as'to alford a neat appearing instrument of such character as to enable the same to be readily vassembled and dismantled for cleaning and other purposes.

Of particular importance among the objects of the invention, is the one piece safety guard, forming a part of the razor structure and which permits of the minute edge of the cutting element to contact with the iiesh without danger of abrasion or injury thereto.

With the foregoing and other objects and advantages in view, the invention has particular reference to certain novel features of construction and arrangement of parts,

which will reveal themselves as the description proceeds, taken in connection with the accompanying drawings, wherein:

Figure 1 represents a side elevational view of the invention assembled.

Figure 2 is a similar view in front elevation.

Figure 3 is an elevational view of the invention in vertical cross section.

Figure 4 is a rear view of the invention in vertical elevation with portions cut away showing the manner o'f'securing the safety guard thereon.

Figure 5 is a detail view of the safety guard in perspective2 and Figure -6 is a detall view of the preferred form of blade used in connection withl the razor herein.

In proceeding more in detail, the invention- 'consists primarily of a hollow handle ,50 portion 1, composed of any suitable nonconducting material. Within the hollow portlon of the handle is disposed a small coil 2 of the usual 110 volt variety, to which the wires 3 are applied as illustrated, and through which the instrument is furnished with the required electrical current.

The handle port-ion l is interiorly threaded at its upper end to receive a cover Li, which latter is in turn interiorly threaded to receive a small tubular member 5, having a shoulder 00 thereon and acting as a housing through which a plunger 6 reciprocates. In contact with the coil 2, a small metal disc 7 is threaded upon the end of the plunger 6, and between the said disc and cover 4, a small eX- e5 pansion spring 8 is interposed to aid in maintaining the disc in intermittent cont-act with the coil, as in Figure 3. l

- Upon the upper end of the plunger 6 and integral therewith is a small cap 9, arranged to conformably lit over the upper end of the tubular member 5, while a small spring 10 surrounds the said member 5 to engage with the cap 9 and an adjusting nut l1 direct-ly therebelow, threadedly movable upon the body of the tubular member 5. It will be observed by reference to Figure 3 of the drawings that the urge of the spring 8 is adverse to that of the spring 10, situated interiorly of the handle 1, such arrangement adding materially to the sensitiveness of the plunger 6. v

A shield 12, the construction of which member is detailed in Figure 5, is provided, which obviates the necessity of employing a as conforming member to-cover the blade, commonly used in the construction of safetyv razors generally.v This shieldcomprises a member preferably as shown, one end of which is bent upon itself and turned outwardly at right angles to the shield proper, at which point it is apertured to receive the tubular member 5, the shoulder of the latter holding the shield from displacement when screwed into position within the cover 4. 05

Particularly in Figures 2 and 5, it will be observed that the shield 12 is longitudinally channeled to receive a slide 13, in which the latter is adapted to actuate longitudinally of the shield, such actuation being imparted thereto through a pin 14, extending through a slot longitudinally cut inthe shield 12, and engaging in an indentation" or aperture in the cap 9. Position of the slide as described is maintained by a bifurcated clip 16, engagingv in slots cut into opposing sides of the pin 14, and is so constructed as to springingly bear against the under side of the shield 12.

A double edged blade 17, illustrated in detail in fFigure 6 is provided, and is -equipped with oppositely directed, semiare shown as being tapered inwardly toward4 the base thereof, whereby one of the apertures of the blade 17 may receive one of the protuberances, while the opposite end of the blade is firmly presseddown upon the opposite protuberance to'snap the blade into rigid position thereon. l

In assembling the instrument for use, the coil 2 is properly connected up with 'the wires 3,I after which it is placed within the body 1. The tubular member 5 is threaded into the cover 4 and the adjusting nut 11 is mounted in its proper place thereon. The

l small spring 10 `is then mounted upon the tubular member 5, and the `plunger 6 inserted therethrough, thence through the cover 4. The spring 8 is then placed around the plunger 6,'after which the disc 7 is threaded upon theA end of the plunger as shown.' After this assemblage is completed,

the' cover 4 is threaded into the handle portion 1, whereby the disc 7 will normally contact with the coil 2.

In assembling the bladeand shield, the slide member 13 is placed within the channel in the shield 12 in such a manner as to per- ;mit the pin 14 to enter the slot 15, and its extremity to lie Within the indentation or aperture in the cap 9, as shown. The bifurcated clip 16 is pressed into position upon the Ipin to prevent dislocation thereof and to hold the slide in perfect alignment with the channel and to eliect its smooth movement therein. The blade 17 is then mounted as previously set forth to complete the assembly.

When electrical current is established Within the coil 2, the intermittent magnetic contact of the disc 7 with the coil obviously imparts a minute reciprocal action to the plunger 6, which, in turn, by reason of the ed rearwardly of said shield having `rocally mounted on said shield, a plungr v pin 14, moves the blade 17 at a high velocity longitudinally through the channel of the shield 12. The adjustment to alter the stroke of the blade 17 is made through the nut 11, which moves 'upon the threads arranged upon the periphery of the tubular member 5, and upon which the spring 10 rests, as previously described.

Certain elements employed herein have been described as being the preferred form .to complete the structure, but it should be understood that equivalent partsmay be substituted in carrying out the invention t0 obtain the best results, without departingfrom the spirit or intent of the invention as set forth in the following claims:
