ELECTRIC RAZOR HAIR CUTTING ATTACHMENT Filed April 12, 1954 United States Patent ELECTRIC RAZOR HAER CUTTING ATTACHMENT Albert S. Haislip, Fredericksburg, Va.

Application April 12, 1954, Serial No. 422,375

14 Claims. (Cl. 34)

The present invention relates to certain new and useful improvements in an attachment for so-called electric razors, or dry shavers, as they are sometimes called, that is, an attachment which is expressly and therefore properly designed and constructed to enable one to cut his own hair.

It will be clear, having read the preceding general statement of the invention, that the art to which the invention relates teaches that it is possible and practicable to provide an appropriately constructed device or attachment which enables users to frequently trim and cut the hair at the temples and above the nape of the neck, thus keeping these marginal areas neat and presentable.

An object of the instant invention is, therefore, to structurally, functionally and otherwise improve upon similarly constructed and performing prior art hair cutting attachments and, in doing so, to provide a novel and distinct construction in which manufacturers and users will find their respective requirements and needs acceptably met.

Although it is within the purview of the inventive concept to provide an attachment which lends itself to cooperative use with various makes of electric razors, the attachment herein disclosed is especially, but not necessarily, adapted to be used in conjunction with a Remington dry shaver. To this end, it is therefore another object of the invention to provide a hair cutting attachment which is characterized, in part, by a specially designed holder which takes the form of a tray-like receiver into which a half-portion of the body of the electric razor is placed, the receiver conforming to the contour of the coacting portion of the body and thus effecting intimate conformation and making it possible to hold the razor and receiver as a unit and to move the razor up and down in vertical paths with the utmost of ease and for adequate guidance in attaining end results with precision and reliability.

Briefly summarized, and regardless of the type of electric razor mentioned, the invention has to do with a hair cutting attachment comprising an adapter which conformably fits itself to and is handily retained on the body of the razor, means including at least one toothed comb which assumes operative relation to the existing or stock cutter means of the usual cutter head of the razor, and additional means for retaining said first named means on said adapter.

Then, too, novelty is predicated on the construction described wherein said first named means embodies two combs, one which travels with an up stroke in a vertical path of movement to collect and cut the hair-ends, and the other which serves to straighten and comb the hairs back to desired place during the down stroke.

More explicitly, the attachment is characterized by a substantially rectangular plate having a lengthwise central bend defining complemental flat half-portions, the respective outer longitudinal edges thereof being toothed and providing progressively and selectively usable combs,

2,?15,Z66 Fatented Aug. 16, 1955 said half-portions being in slight divergent relation in respect to said bend, one of said half-portions having key-hole slots therein, and the combination therewith of a tray-like razor receiver and holder, the latter open at one end and provided with a lateral support flange, said flange having headed retainer-studs and the latter serving to accommodate said key-hole slots, whereby said plate is detchably connectible with said flange.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying sheet of illustrative drawings.

In the drawings:

Figure 1 is a perspective View showing a hair trimming or cutting attachment constructed in accordance with the principles of the present invention and illustrating the manner in which it is fitted for use on an electric razor;

Figure 2 is a perspective view of the adapter with the comb means removed;

Figure 3 is a view in section and elevation based on Figure l and which shows, in dotted lines, how the comb means may be adjusted to bring the comb closer to the cutter head of the razor;

Figure 4 is an enlarged fragmentary sectional and elevational view taken on the approximate line 44 of Figure 1, looking in the direction of the arrows;

Figure 5 is an elevational view of the readily applicable and removable plate or dual comb means by itself; and

Figure 6 is an elevational view showing in full and phantom lines how the attachment is used in cutting the hair by way of an upstroke and combing the hair back down and smoothing it by way of a downstroke.

It is, of course, obvious that the particular make or kind of electric razor is no part of the invention. It has been found, however, that the particular adapter used lends itself admirably well for employment in connection with a Remington electric razor, the same being denoted in the drawings generally by the numeral 8. The usual reciprocating cutter head construction is denoted at It The adapter will vary in construction according to the kind of razor with which it is to be employed. Therefore, an essential part of the over-all attachment is an appropriate adapter and this is generally denoted by the numeral 12. As perhaps best shown in Figure 2, it not only is such that it conformingly fits the razor, it provides a holder for the razor and makes it possible to actually clamp the razor therein so that the two may be used in firm relationship to insure precision results. Specifically, the adapter takes the form of a receptacle-like receiver which is perhaps best referred to as a tray-type receiver and it therefore is characterized by a bottom 14, which is shaped up to fit the razor 8. Incidentally, the razor may be placed in from either side with the adapter being approximately of a depth equal to one-half the thickness of the razor body. Then, too, the bottom 14 conforms to the coacting surfaces of the razor body. The receiver is open at one end, the top in Fig. 2. It is provided on opposite sides with outstanding and suitably shaped flanges, called

side flanges

16, 16 and these are duplicates and also have duplicated

clearance notches

18, 18 for the switch button 20 on the margin of the razor. The intervening end flange is denoted at 22. At the open end 24 there is a laterally bent support flange 26. This is provided with studs (see Fig. 4) denoted by the

numerals

28, 28, said studs passing through the flange and providing

headed retainers

30, 30. Also shown in Fig. 4, the

central portion of the flange has a tapered hole 32 therein to accommodate a ball-detent 34 which is yieldably held in the opening or hole 32 by way of a coacting portion 36 at the center of a leaf spring. The spring 38 has appropriate bends to impart the necessary ten- 3 sion on the ball-detent. The

end portions

40, 40 of the springs are secured in place by the studs 28'; 281

The adjustable and detachable comb means is denoted as a unit by thenumeral 42.. This; comprises a. substantially. rectangular plate which. as.- shown in. Fig, 5" hasxa central". lengthwise bend. 44 which transforms. the plate into substantially fiatj rectangular half-

portions

46 and 48. These half portions are. providedwith. teeth 50'formingone comb on one side oftheplateand additional teeth 52 providing. the comb. on. thefother side of the plate. It is: alsdevident. from, Fig. 5 that the half-portion 48 is provided. with longitudinally spaced key-hole shaped" slots 54' which are. located. to. accommodate the retainer heads 30 in the, manner; i1: lustrated in Fig. 4; Opposite side surfacesofthi'shalf portion 48 are provided withsmall depressions 56'. which constitute selectively usabl'e keeper seatsfor, the balldetent 3.4 in the manner also illustrated in Fig. 4.. The spring thrustball-detent serves. to make sure that. the dual comb plate 42' is eflectively maintained imposition. It' is easy to actually snap the plate on and off inv a rather obvious manner. That is to say, the larger. ends of the key-hole slots are placed over. the heads'30 andthen the plate is slid endwise bringing the heads into the narrow ends of the slot and holdingtlie plate in position. Sliding of the plate accidentally in an opposite releasing direction is resisted by the ball-detent 34" engaging in the cooperating keeper seat 56; It is also to be noted that the respective combs 5.0 and 52 are at slight divergent angles and. therefore converging toward the bend 44. The purpose of this slight slanting is to permit the plate to be readily applied and removed and the comb 50 turned over or. reversed and in this manner is adjusted so that the teeth are farther away from the cutterhead' 10; as shown in Fig 3 in full lines, or closer to'the cutter head, as shown in dotted lines.-

It is also within the purview of the invention to either increase or decrease the angularity of the respective combs so that itis possible to get several spacing ad+ justments between the cutter head and' comb whichv is then inuse. This means that the comb plate. 42 may be described as adjustable in the sense that it is reversible simply by taking it off and putting it back. on. with the desired combin place either close to or far from the'cutterhead.

In practice, the razoris seated in the receptacle portion of the tray-like adapter-so that the adapter virtuallybecomes a part of the razor'and the. two may be grasped and used in a solid properly associated relation as" brought out in the drawing particularly in. Fig. 6.

In'full lines in Fig. 6 one sees how the device isheld and moved on an upstroke in avertical path to. allow thehair ends to be distributively collected between the slots inthe teeth 50; Thetips' of the hair ends come into cutting relation with the cutter head and thus are clipped an obvious manner. The upstroke is the hair cutting stroke and the downstroke is the combing' stroke, and at this time, as shownin Fig; 6 in dottedlines the lower comb, here described with the teeth 52 isdragged down as any comb would be to straighten out and smooth the hair for the next cutting stroke. Instead of having to hold a. comb in one hand the hair cutter-with a single comb in the other hand, both combs are-on the one plate making it an unusuallyhandy and reliable construction to attain the desired ends to the utmost in satisfaction.

From the foregoing, the construction and operation of thedevice will be readily understood and further explanation is believed tobe unnecessary. However;

since numerous modifications and changes will readily" occur to those skilled in the art, it is not desired to limit the invention to-theexact construction shown and described, and accordingly all suitable-modificationsand equivalents may be resorted to, fallingwithiirthe scope of the appended claims.
