HAIR TRHHMING A'ITACHMENT FOR ELEC- TRIC RAZORS Leon' M. Coles, Port Chester, N. Y. Application January 19, 1939, Serial No. 251,672

v 4 Claims.

This invention relates to new and useful improvements in electric razors or socalled dry shavers and has particular relation to a hair trimming attachment for such razors or dry shavers.

The objects and advantages of the invention will become apparent from a consideration or the following detailed description taken in connection with the accompanying drawing wherein satisfactory embodiments of the invention are shown. However, it is to be understood that the invention is not limited to thedetails disclosed but includes all such variations and-modifications as fall within the spirit of the invention and the scope of the appended claims.

In the drawing:

Fig. 2 is an enlarged plan view of the attachment;

Fig. 3 is an enlarged plan view of the razor head;

Fig. 5 is a view similar to Fig. 4 but showing a slight modification;

Fig. 6 is a view at right angles to Fig. 5;

Fig. '7 is a view similar to Fig. 1 but showing the application of the invention to a slightly different type of razor, the handle of the latter being broken away;

Fig. 8 is an enlarged transverse sectional view of the attachment t Fig. 7; v

Fig. '9 is an enlarged top plan view of the attachment;

Fig. 10 is an enlarged top plan view of the head of the razor of Fig. 7; and

.Fig. 11 is an enlarged transverse sectional view of said head.

Referring in detail to the drawing and at first to the form of the invention shown in Figs. 1

through 6, at I0 is generally indicated an electric razor or dry shaver including a handle I I Cutter 12 includes an outer stationary element l4 and an inner movable element I5, the latter during use of the razor,'being reciprocated in the well known manner by a power means (not shown) within the handle ll:

Each of the elements l4 and I have teeth along their opposite longitudinal edges and the' teeth on the respective elements are designated 16 and [1 respectively. In the use of the razor the other of the razor is cut ofi as the element I5 is reciprocated. Obviously the foregoing briei. description relates to 'a well known construction of electric razor.

The attachment of the invention is generally designated l8 and is shown complete in Fig. 1. Such attachment is preferably made of stainless spring steel and includes a pair of arms l9 and a connecting portion 20 extending between said arms. Arms l9 are arranged at opposite transverse edges or sides of the handle ll while connecting portion 20 spans the cutter means, being disposed across the outer side of cutter element IQ.

Arms I! each include extensions or lugs 2| located to engage the front and rear or the wide sides of the handle ll whereby to hold the attachment on the razor against movement of portion 20 back and forth across the cutter element 12. It will be apparent that the arms l9 will prevent movement of the attachment in a direction cross wise of the cutter teeth of the razor.

When the attachment is made of spring steel the arms I9 and the lugs 2| are to tightly embrace the razor handle whereby to keep the attachment in place on the razor. However, if desired an elastic band 22 is provided to encircle the razor handle and the said arms l9 and lugs 2| and to clamp them against the handle whereby to keep the attachment in the desired position on the handle the adjustment made possible by the construction described being for a purpose to appear.'

As herein suggested (see Figs. 1 and 4) the sides of the handle II are provided with vertically extending slots 23 receiving lugs 24 carried by the arms IS. The elastic band 22 keeps the arms l9 against the sides of the handle and the said lugs 24 are thus kept in the slots. Obviously the lugs and slots provide for adjustment to dispose the attachment portion 20 in more or less spaced relation tothe cutter element 14, as may be desired.

Along its opposite longitudinal edges the attachment portion 20 is provided with teeth 25 and 26. Teeth 25 are much finer than are the teeth 26 and the purpose of this construction will appear. The outer end portions of both sets of teeth are tapered to facilitate the entrance of hair between the teeth but the extreme outer ends of the teeth are rounded or at least blunted so as not to readily prick the skin of a user.

Teeth 26 in their edges are notched as at 21.

hair entering between the teeth at one side or Preferably the notches in the teeth are of such shape as to result in the formation oi. straightment I4.

Figs. 5 and 6 show another arrangement whereby the attachment may be secured to the razor for adjustment relative thereto. In these figures the arms l9 of the attachment are provided with slots 30 extending vertically of the arms and set screws 3| or the like passing through such slots are threaded into the handle. Obviously on loosening of the screws 3| the attachment may be adjusted to position its connecting portion 20 in the desired relation to the cutter element I4. Thereafter the screws willbe tightened. i

In using the device the operator when he wishes to trim the hair from the back of his neck securesthe attachment to the razor with the ,portion 20 against the cutter element l4. This positioning is also suitable for use in the trimming of the sideburns. To trim his hair the. operator adjusts the attachment to have its connecting portion 20 disposed about one-.- eighth of an inch from the element I4.

The device is preferably used with an up and down motion, the coarse teeth 26 being drawn through the hair as the device is moved upwardly and then the device is tilted in the opposite direction and the fine teeth 25 passed through the hair to comb it as the device is drawn downwardly. The coarse teeth 25 should not be more than one thirty-second inch wide and the notches are as deep as may be made without unduly weakening the teeth. The fine teeth may be one-' half the width of the coarse teeth. 1

During the use of the device as a trimmer the teeth 25 and 26 direct or guide the hairs to be cut to the cutter means of the razor. The notches 21 in the teeth serve to hold the hairs to the cutter means. That is, the hairs against the shoulders of said notches cannot spring away from the cutters. Further the notches permit the hairs to spread along the cutters so that the hairs while held are not held in bunches and may enter between the teeth of the cutters. Therefore the cutting operation is facilitated.

In connection with the feature of the shoulders of the notches holding the hairs to the cutter it will be apparent. that (see Fig. 2) the shoulders 29 of the intermediate set of notches will be particularly effective with the razor shown. Such shoulders are located just beyond the outer ends of the teeth of the guard or element l4, the ends of the teeth being in the line 32 and the teeth being shown in dotted lines. The ends of the teeth I5 being slightly short of the shoulders the hairs held by the shoulders may move into the slots or spaces between the teeth. The purpose of the various sets of notches is to have at least one set of shoulders located for cooperation with the teeth of the razor. Where several closely located sets of shoulders are provided as shown one set will be properly located after anyadjustment of the attachment'and should the attachment change position slightly due to wear or the like.

Referring now to theform shown in Figs. 7 through 11 at 40 is generally indicated another type of electric razor or dry shaver including a handle 4i and a cutter means generally indicated at 42. Means 42 includes an outer stationary element 43 and an inner movable element 44 adapted to be reciprocated by a power means (not shown) within the handle 4| as is well understood in the art. Element 43 and 44 are oi substantially the same cross sectional configuration and a cross section of the element 43 is shown in Fig. 11.

Each element is provided with slots 45 in the Aorgn 0! an inverted U opening through both the top and the sides of the elements, the slots being best shown in Figs. 10 and 11. In the use of the device the hairs to be cut enter into the slots 45 in the element 43 and the corresponding slots (not-shown) -in the element 44 and are cut oil 1 as the element 44 is reciprocated in element 43.

This is a well known razor now on the market.

' formation of teeth 52 which are of inverted U- shape. Teeth 52 are tapered toward their outer ends as viewed in plan (Fig. 9) to facilitate the entrance into the slots of the hair to be cut. The teeth guide or direct the hair into the cutter means of the invention.

As clearly shown in Fig. 9 the teeth 52 are notched in the sidesof their connecting portions to-provide shoulders 53' which, during use of the device, serve to hold the hairs to the cutter and yet to permit the hairs to spread along the cutter means whereby the hair 'is not presented in bunches to the cutter. Thus it will be seen that the purpose of the notches in the teeth 52 is the same as that above fully described whe considering the notches in teeth 25.

Handle 4i is provided with a recess 54 into" which snugly fits the attachment extension 50.

when the attachment is applied to the razor. .At such time the connecting portion 41 of the attachment is disposed over the cutter means'oi the razor and the attachment may be described as straddling the cutter head. Thus the teeth 52 of the attachment serve to guide to the cutter teeth of the razor the hairs which are to be cut. Further teeth 52 serve to hold such hairs to the cutters while yet permitting them to spread along the cutter.

The extension 50 is bifurcated as best shown in Fig. 7 and straddles the screw 55 in the recess 54. Obviously the screw serves to clamp the extension against the body of the razor handleand the extension having a snug fit in the recess the attachment is held against turning movement relative to the razor. On loosening of thescrew the position of the attachment may be adjusted or the attachment may be removed from the razor if the latter is to be used for shaving. In making the adjustment with either form of the attachment the connecting portion thereof is brought closer to or moved outwardly from the cutter means of the razor.

Having thus set forth the nature of my invention, what I claim is:

1. In combination with a power razor comprising a handle having acutter means at one end thereof and a power means in the handle for operating said cutter means, said cutter means including an outer stationary element and an inner movable element, each of said elements elongated and having teeth opening along its op-.

strokes, and resilient means encircling the razor handle and clamping the arms of the attachment against the handle.

2. In combination with a power razor comprising a handle having a cutter means at one end thereof and supporting a power means for operating said cutter means, said cutter means including an outer stationary element and an inner movable element, each of said elements elongated and having teeth opening along its opposite longitudinal edges, a hair trimming attachment for said razor, said attachment including arms against the transverse sides of said handle, an elongated part extending over said outer cutter element, said part having teeth opening through its opposite longitudinal edges for guiding hairs to said elements whereby to have the razor cut on the up and on the down stroke, and lugs on the edges of said arms and clampingly engaging the longitudinal sides of the handle whereby endwise and transverse movement of said part relative to the cutter means is prevented.

3. In combination with a power razor comprising a handle having a cutter means at one end thereof and power means in the handle for operating said cutter means, said cutter means including an outer stationary element and an inner movable element, each of said elements elongated and having teeth opening along its opposite longitudinal edges, a hair trimming attachment on said razor, said attachment including arms against the sides of the handle, an elongated part extending over said outer stationary element, said part having teeth opening through its opposite longitudinal edges for guiding of hairs to said elements whereby to have the razor cut on up and on down strokes, and said teeth along one longitudinal edge of said attachment having rows of notches in their edges to hold the hairs to be cut to said cutter means and to permit the hairs to spread along the cutter.

4. A hair trimming attachment for an electric razor comprising an elongated piece of sheet metal bent transversely at a pair of spaced points into a generally inverted U-shape whereby the attachment includes a pair of arms and a connecting portion between said arms, said connecting portion including a solid intermediate portion, rows of fingers on the opposite tree edges of said portion and in the plane thereof with the fingers of one edge separated from those of the other edge by said intermediate portion, integral lugs on the opposite edges or each of said arms, and

' said lugs 01 each arm extending toward those 01' the other arm.
