GUARD FOR RAZORS AND HAIR CLIPPERS Filed May 25, 1956 IlllllllllllllllllllllII"gm INVENTOR;

BY GEORGE PHIL/P sum/7r A ORNEY.

Patented June 15, 1937 UNITED STATES PATENT 'OFFlCE 3 Claims.

This invention relates generally to guards for razors and hair clippers and particularly to guards for razors and clippers of the power-driven class. i

Power-driven shaving or clipping devices in vogue today usually employ a skin-engaging plate or member having a series or plurality of slots forming blades between the slots and a cutter having a plurality of cutting edges, located at the rear of said slotted member. The blades of the slotted member and the cutting edges of the cutter cooperate to do the cutting or nipping of the hairs without the use of soap or a beard softener. The operating power is usually supplied to the cutter by means of an electric motor or coil and through intermediary connection or connections. I I 1 Amongst the prior art are to be found, in particular, two types of power-driven razors. In

both these types the cooperating cutting members comprise a skin-engaging slotted shear plate and a slotted cutter. In one of these types the skinengaging surface of the shear plate is flat or substantially so, and in the other type the skinengaging surface is arcuate. Both these types have certain desirable featuresbut are encumbered with grave disadvantages resulting in a lack of utility and of efllciency to bring about the desired result, namely, to accomplish a very close cutting of the hairs without discomforture and pulling of hairs and without subjecting the skin to scraping action or irritation when the fin-engaging shear plate is moved along the n. v For example, a skin-engaging slotted shear plate of arcuate or cylindrical form presents a smooth, non-irritating surface for engagement with the skin but has not the cutting hair-guiding qualities of a flat surfaced slotted shear plate, especially of the typ having the ends of the slots open for hair admission purposes; whereas, the fiat surfaced slotted shear plate lacks that smooth, gliding effect upon the skin, and in fact, -irritates and sort of "digs into" the skin and causes pulling of the hairs upon manipulation of the instrument.

My invention, among other important features, supplies the aforementioned advantageous feature of the arcuate surfaced skin-engaging shear plate to the flat surfaced one to produce a very efficient, comfortable and effective hair cutter."

This is accomplished by providing a pair of guards having arcuate surfaces and between which the flat surfaced shear plate is disposed.

The advantageous features of this invention are attained by the novel design, construction and arrangement of parts, as hereinafter described and illustrated in the accompanying drawing, constituting a feature of this disclosure, and in which: 1

Fig. 1 is a perspective view of a razor or hair clipper guard embodying the invention.

Fig. 2 is a perspective view of a razor or hair clipper guard embodying the invention in a somewhat modified form and showing the position of the guard with respect to the cutter head, the latter and handle being shown in phantom outline.

Fig. 3 is a top view of Fig. 2.

Fig. 4 is a fragmentary perspective view of a guard in a still further modified form.

Figs. 5 and 6 are end views of respective razor cutter heads showing the guards as being joined to the stationary plate housing.

In Figure 1 of the drawing numeral I0 represents in general a preferred construction of a guard member capable of being applied to, for example, a form of power razor or hair clipper having a hollow, stationary member or housing II provided with a flat skin-engaging slotted shear plate I2 and which houses a reciprocable slotted cutter element I3 having the usual cutting edges (not shown); The shear plate I2 has a plurality of alternately arranged transverse slots and blades I4, I5, respectively, the cutter being located in the rear of plate I2. Each blade is provided with end projections I6, usually tapered, the slots I4 having open ends so that the hair is guided by projections I6 for reception or admission within slots I4 as the device is moved overthe skin for the cutting operation. The hairs are admitted through the open ends of the slots between projections I6 and are cut or clipped by the cutter as the latteris made to reciprocate by any suitable means, such as an electric motor or coil (not shown) usually housed within handle I1.

The above general description is merely explanatory and does not form part of the invention.

The guard member may comprise generally a standard or frame having a base upon which are secured end brackets or supports carrying the preferably arcuately-sectioned guard ele I 'ments. Figure 1 shows a preferred construction of guard member I0 having the base I8 with upturned ends I9 and brackets or supports 20 secured to ends I9 in any suitable manner, such as, for example, solder 2|. Each support 20 has crossing legs 22, the upper ends 23 of which are bent substantially at a right angle and parallel with respect to each other. Carried by the upper ends 23 of supports 20 are the spaced and parallelly disposed longitudinal guards 24.

These guards 24 are preferably rollers rotatably mounted on ends 23, but may be curve-surfaced elements, such as, for example, tubular or cylinder-like elements fixed to ends 23.

The brackets or supports 20 may beseparate parts or may form an integral unit. Instead of the legs of the supports being crossed they may be parallel as indicated by the number 28' in Figure 2. Base It has an opening 25 through which the conventional lever or eccentric pin.

26 may pass for engagement with the movable cutter I3 to cause reciprocation of the latter.

Base l8 may be also'provided with a smaller opening 2? for extension or" the conventional lo eating pin 28.

Figure i shows the base as being a fiat plate 08' having the substantially iJ-shaped end supports 253', secured thereto. in this case the end supports 26' are joined together by the spaced parallel sections 29 upon which are mounted the individual beads or rollers The supports 2d and sections 2? may be formed out of a single piece of wire.

The top of handle it is usually channelled or grooved to receive the cutter head which com 39 prises the housing it and cutter element i8. When the guard device is in position, base 08 or it'is located between the bottom of the cut= ter head and the bottom of the channel, the top M of the cutter head extending slightly above the W guards 2 3.

It can readily be seen that as the razor is moved over the skin, the guards 2G or 3t) present a smooth, sliding or rolling surface in con- A tact with the skin and prevent any possibility of the projections i6 scraping or irritating the skin during the shaving operation.

Figure 5 is an end view of a razor cutter head I showing guards 30. These guards are prefer- 45 ably made of plastic composition molded onto the stationary shear plate housing ii in any suitable manner. In Figured the guards 532 may be rollers orstationary rods secured in any Although I have described my improvements with respect to certain particular forms of my invention, I do not desire to be limited to such details since many changes and modifications may-well be made without departing from the spirit and scope oi! my invention in its broadest aspect.

Having thus described the invention, what is claimed as new and desired to secure by Letters Patent, is:

1. The combination with a power razor having a handle and a slotted cutter head carried by the handle, said cutter head having a movable cutter therein, of a guard device comprising a pair of parallel longitudinal guard members, and a frame carrying said guard members, said frame including a base interposed between the cutter head and the handle, said guard members being spaced apart and receiving the cutter head therebetween.

2. The combination with a power razor hav ing a handle and a slotted cutter head carried by the handle, said cutter head having a movable cutter therein, of a guard device for said razor comprising a pair of parallel longitudinal guard members having smooth surface skinengaging peripheral surfaces, a base interposed between the cutter head and the handle and carried thereby, and means supported by opposite ends of said base and carrying the guard members in laterally spaced relation on opposite sides of the cutter head and adjacent the cutter to prevent the cutter head from irritating the skin during the cutting operation.

3. The combination with a power razor having a handle and a slotted cutter head carried by the handle, said cutter head having a movable cutter therein, of a, guard device for said razor comprising a base interposed between the cutter head and the handle and carried thereby,

and a longitudinal guard member carried by said base and disposed beside the cutter head and
