LEON M.COLES BY 1 r Y Y ITTURIVEY Patented July 15, 1947 UNITED STATES PATENT OFFICE ATTACHMENT Eon POWERRAZORS To FACILITATE HAIR TRIMMING 6 Claims. 1

This invention relates to new and useful improvements in electric razors or dry shavers and has particular relation to a combination of an electric razor or dry shaver and a hair trimming attachment therefor.

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

In the drawing:

Fig. 1 is an elevational view of the upper portion of a dry shaver having the attachment of the invention applied thereto and showing the attachment in its upper or outer position;

Fig. 2 is a similar view showing the attachment in its inner position;

Fig. 3 is a plan View of the blank prior to the bending up of the same to fOrm the attachment;

Fig, 4 is a view similar to Fig. 1 but showing a slight modification; and

Fig. 5 is a front elevational view of the razor and attachment of Fig. 4 but with the attachment in its innermost position.

Referring in detail to the drawing, and at first more particularly to Figs. 1 through 3, at In is generally indicated an electric razor or dry shaver including a handle I I and a cutter head I2 at one end of such handle. The construction of the cutter head is not of particular interest here but generally the cutter means of these devices includes an outer stationary element and an inner movable element, which latter, when the razor is in use, is reciprocated in a well known manner by power means (not shown) located within the handle II.

The teeth of the cutter means are generally located at opposite longitudinal edges of the head so that in either direction of movement of the razor hair to be cut will enter through the cutter means and be cut off as the inner cutting element is reciprocated. All of the foregoing description relates to well known structures of electric razors and is given merely by wayof setting forth general constructionof such devices in order that the operation and use of the attachment of the present invention will be fully understood. U

The attachment of the invention is generally designated I3 and is shown as of a one piececone str'uction including a pair of arms I4 and I5 and an elongated part I6 connecting said arms. The blank from which the attachment is formed is shown in Fig. 3 and there it will be seen that the elongated part I6 is provided in one longitudinal edge with relatively fine teeth IT and in its other longitudinal edge with coarser teeth I8, the formation of each such set of teeth providing openings for guiding hairs to a cutter head as will become apparent. Between its edges portion I6 is provided with close together, narrow slots! adapted to function with the type of razor shown in Figs. 4 and 5. When forming the device of the invention the generally U-shaped contour of the attachment is obtained by bending the blank of Fig. 3 along the dotted lines I9 and 20.

The razor handle II in its edges 2| and 22 is provided with concave portions 23. Attachment arms I4 and I5 are also bent to a concavo-convex shape so that when the connecting part I6 of the attachment is in an outer position, as in Fig.1, the arms I4 and I5 fit snugly into the concave portions 23 in the edges 2| and 22 of the handle II. On their front and rear edges the arms I4 and I5 are provided with upper and lower lugs 24 and 25 respectively and the lugs of one arm extend toward those of the other arm so that when the attachment is on the razor the lugs from the forward edges of the arms are against the front side of the razor handle while the lugs on the rear edges of the arms are against the rear side of the razor handle, the arms themselves being against the edges of such handle.

The entire device I3 or at least the arms I4 and I5 thereof are of spring metal whereby such arms, when the attachment is positioned as in Fig. 1, closely embrace the edges of the handle I I. The curve of the arms is such with respect to the curve 23 of the edge portions of the handle that the arms are constantly tending to shift the entire attachment to the position of Fig. 1 so that said arms may follow the curvature 23 0f the handle.

The device is shiftable from the position of Fig. 1 where part I6 is substantially spaced from the cutter means I2 to the position of Fig. 2 where the part I6 is substantially against said cutter means. This shifting of the attachment results in a forcing or spreading of the arms I4 and I5 with respect to the edges of the handle so that immediately the attachment is released, when positioned as in Fig. 2, the spring arms act to shift the attachment to the position of Fig. 1.

When trimming the hair the operator places his index and meme fingers on slight u s it formed on the upper edges of the upper lugs '25.

Then by flexing his fingers he may draw the attachment inwardly so as to dispose the part l6 close against the cutter head 12 or as close to the cutter head as he may desire. Occasionally by straightening his fingers he permits the attachment to move to the position of Fig. 1 where tapping the device will serve to discharge all cut hairs therefrom.

From this it will be seen that while holding the razor the user simply by bending his index and middle fingers shifts the attachment so as to dispose the elongated part IE in the desired relation to the cutter means l2 and that by simply permitting his fingers to straighten the device is permitted to move to an open position so that out hairs may be readily knocked from the device. The lips 26 are not essential but are provided as a convenient means to eliminate any sharp edges which might otherwise be engaged by the operators fingers.

Figs, 4 and are for the purpose of showing how the attachment may be applied toa razor having a different shape of handle and a different construction of cutter head. In. such figures the razor is generally designated 36 and the same includes a handle 3! which is reduced in width towards its outer end at which cutter head 32 is located. This type of handle is provided with a suitable stop means here shown as a pair of beads 33 arranged one on each edge of the handle adjacent the cutter means.

In the modification, the attachment is generally designated 34 and the same includes side arms 35 and 35 and an elongated part 3'! connecting such arms and of the construction of the part it of the figures first described. That is, the part 3? is provided in its longitudinal edges with teeth I1 and it! and intermediate such edges with the slots 40. Further, the arms of the attachment 34 are provided with lugs 24a and 25a corresponding with the lugs 24 and 25 previously described. In this case, the lugs 25a are provided with,the slight lips 25a corresponding with the lips 26 of the figures previously described.

Intermediate their ends, the arms 35 and 36 are provided with offset portions 38 and 3S respectively and which portions are adapted to engage with the beads or other stop means 33 when the attachment is in an outer or released position as in Fig. 4. Arms 5 and 35 are of spring metal and are so set as to substantially constantly hug the edges of the handle 3! and owing to their spring action and the shape of the handle the spring action of the arms constantly tends to shift the entire attachment to the outer or released position of Fig. 4.

In using the device, the operator engages a pair of the lugs 26a with his index and middle fingers and holds the. device inwardly with the elongated part 3'! in the desired relation to the cutter means 32. Simply by releasing the attachment the spring action of its arms cooperating with the shape of the handle shifts the attachment to the position of Fig. 4 so that cut hair may readily be knocked from the device. As the device is used hair entering through the slots 69 passes into the cutter head 32 (Schick type) and is cut. In this connection it is noted that the slots are preferably of lengths greater than the width of the cutter head 32 so that some hair entering the slots may enter the side openings of the razor head.

It is believed that the construction and operation of the present hair trimming device will now be fully understood but here it is pointed out that owing to the construction of the side armsof-the two attachments shown and their shape together with that of the shape of the razor handles the arms are constantly tending to cause the entire attachment to ride outwardly on the razor, as to the position of Figs. 1 and 4. In Figs. 1 and 2 the shape of the arms together with the shape of the razor handles limits this outward movement to approximately that shown in Fig. 1, and in Figs. 4 and 5 the beads or other stop means 33 together with the oiTsets 38 and 39in the attachment arms limit outward movement of the attachment approximately to the position shown in Fig. 4.

The device is easily moved inwardly from this outward position either to the positions of Figs.-

2 and 5 or to any intermediate positions as may be desired by the operator. Since the arms of each of the attachments are, in effect, springs constantly pressing against the razor handle the movement of the attachments by the operator as described is always with ease and smoothness. Further, the spring or resiliency of the arms enables the device or attachment to be easily sprung over the end of the razor, off and onto the razor. Thus the attachment may easily be removed from the razor for cleaning of the shearing head and may be easily replaced.

When the device of the invention is used on the type of razor of Figs. 1 and 2 the teeth l! or I8 serve to guide the hairs to the cutter head and to raise the hairs into the cutter head. On the type of razor of Figs. 4 and 5 the teeth raise the hairs, moving them out from the head and combing them backwards. These raised hairs spring into the openings or slits 40 and thus are presented to the cutter.

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