COMBINED SAFETY RAZOR AND SHARPENING DEVICE Louis V. Aronson, Newark, N. 1., assignor to Art 3 I I Metal Works, Inc., a. corporation of New Jersey Application December 15, 1931, Serial No. 581,132

8 Claims. (01. 30-12) This invention relates to improvements in combined safety razorsand sharpening devices.

The features of this invention include certain improvements which have been shown for the purposes of illustration as applied to the type or" razor shown in my copending application Ser. No. 552,843 filed July 24,1931. In thistype of razor a sharpening device, such as an abradant roller or other means which may be conveniently operated by the hand, is attached to the head of the razor and is intendedto form a permanent part of the device, and a double-edged razor blade is so mounted on the device that either of the two blade edges may be brought into contact with the razor guard for shaving, or with the sharpening device for sharpening, without removing the blade from its clamping means. The razor shown in said application is provided with improved. means for moving the razor blade into a position in which it may be turned about its longitudinal axis as well as about an axis at right angles to its plane, together with improved means holding the razor blade in a position outside of the razor head for facilitating cleaning and replacement of the blades, and improved means for aligning the razor blade with respect to the razor head. 1

. Among the objects of this invention are the pro vision of a honing roller, or otheriorm of honing device, and. a stropping roller or other form of stropping device, together with means for.

mounting them on the razor head so that either or" the rollers or devices may be brought into cooperative position with one of the edges of the razor blade.

Another object of the invention is the provision of means whereby either face of either edge of a double-edged razor blade maybe brought into cooperative position with either ahoning roller or other form of honing device, or a stropping roller or other form of stropping device, without dismountingeither the rollers or the razor blade from the razor. 7

Another object of the invention is the provision of means whereby either a honing roller or other form of honing device, or a stroppingroller or other form of stropping device, may be moved into cooperative position with an edge of a razor blade while supported on the razor.

Still another object of theinventon is the provision of an improved'honing roller.

Still another object of theinvention is the provision of a common support for a honing roller and a stropping roller or other forms of honing and stropping devices movably and rotatably r cs mounted on the razor head so that the support may be moved to carry said rollers or devices into and out of cooperative position with respect to a razor blade supported on the razor by any suitable means.

My improved razor includes a razor head 10 which is of general box-like formation with the upper end open and which may be formed of apiece of sheet metal. A suitable guard 11- have ing raised end guard teeth 12 may be formed on or suitably secured to one side of said head by any suitable means. The end walls of the head are preferably provided with slots 13 in which operate closely fitting pins 14 carried on a frame member 15 which is of general U-shapc, as shown, and which pivotally supports a moiuiting 16 for a razor blade 17 which is held on the mounting by an outer clamping member 18 secured in position by a thumb bolt 19, as indicated in Fig. 3. The mounting 16 may be provided with raised lugs 20 at its ends which enter correspondingly shaped notches in the razor blade and the outer clamping member to align the razor blade with its mounting, as is well understood.

In the application referred to, mechanism is provided sfor presenting either face of either edge of a double-edged razor blade into cooperative position with a sharpening roller. This mechanism includes, in addition to the means for pivotally supporting the blade on the U shaped member 15, means for raising the ilshaped member 15 to carry the blade beyond the roller into a position where the blade may be rotated about the pivot on the U-shaped frame member, and where the U -shaped member may be rotated to move either edge of the blade into cooperative position with the sharpening roller. This means includes a plunger 21 non-rotatably secured to the U-shaped frame member 15 and slidably mounted within a handle section 22 which is rigidly secured to the razor head 10. The plunger extends beyond the handle section 22 and has secured to its lower end a manipulative member 23 which is provided with a skirt portion 24 slidably engaging on the outer face of the handle section 22. The blade 17 is moved into cooperative position with respect to the guard and sharpening roller by means of a spring 25 which is seated on a shoulder within the handle section 22 on the bottom of the recess in the manipulative member 23. For the purpose of facilitating the movement of the blade out of cooperative position with the guard and the sharpening roller, and for rotating the blade about an axis through the plunger 21, the handle section 22 is provided with a finger engageable portion 26, and the manpulative portion 23 is provided with a smooth end portion 27 and a fluted outer surface 28, as indicated in the drawings.

In the construction shown in Figs. 1, 2, 3 and 4, I have shown two sharpening devices in the form of rollers, one of which is indicated at 30 and may be used for honing operations, and the other of which is indicated at 31 and may be used for stropping operations. As shown in these figures, these rollers are rotatably supported on ears 32 which are formed on the end walls of a plate 33 which is provided with a centrally located hub portion 34 bearing on an internally threaded stud 35 which is secured rigidly to the side of the razor head 10 by any suitable means. The roller supporting plate 33 is held on the P stud 35 by means of a screw bolt 36, as indicated in Fig. 3. By means of this construction, when the razor blade is moved into the position shown by broken lines in Fig. 4, the

rollers

30 and 31 may be rotated as indicated in said figure so as to present either roller into cooperative relation with the edge of the razor blade which is in position to be sharpened.

By means of the construction so far described, the razor blade may be moved into the position shown by broken lines in Fig. 4 by pressure on the end 27 of the manipulative portion 23, after which the razor blade may be turned about an axis through the plunger 21 so as to reverse the position of the edges of the razor blade with respect to the sharpening rollers and the guard. This movement is facilitated by the fluted skirt portion 28 of the manipulative member 23. By this operation one face of either edge of the razor blade may be presented into cooperative relation with the sharpening rollers, and for the purpose of presenting the other face of the corresponding edge to the sharpening rollers the razor blade is again elevated and turned through an angle of 180 about an axis through the plunger 16 and also turned through an angle of 180 about an axis through its length, as is obvious.

When it is desired to hone the razor blade the roller 30 is moved into the position shown in Fig. 3. Each face of each edge of the razor blade may be, as stated above, brought into cooperative relation with the honing roller. After this operation is completed the razor blade may be moved into the position shown in Fig. 4 and the sharpening rollers may be rotated as indicated in Fig. 4 until the stropping roller 31 oocupies the position in which the honing roller 30 is shown in Fig. 3, after which the pressure on manipulative 23 may be removed and the razor blade returned into its normal position, indicated in Fig. 3, by the spring 25.

By means of this construction the razor blade may, because of the necessary working clearance between the movable and stationary parts, adjust itself so that the edge of the blade in shaving position will properly align with the guard teeth, this movement being facilitated by the fact that the rollers are mounted so that they may adjust themselves to the other edge of the blade. The pivoted mounting of the roller supporting plate on the razor head also facilitates the sharpening operation in that the rollers may adjust themselves to properly cooperate with the edge of the blade as the blade is drawn inwardly by the spring in the handle.

In the modification shown in Figs. 5, 6 and '7, I have provided means for moving the rollers laterally away from the head so that during the operation of reversing the position of the rollers with respect to the face of an edge of the razor blade, it will only be necessary to hold the razor blade in its normal position or, if desired, raise the razor blade a short distance away from the face of the cooperating roller. In this construction the plate which carries the rollers is provided with a laterally projecting manipulative member 3'? by means of which the rollers may be moved laterally and rotated, as described with reference to Fig. 4. Said operating member includes a partition 33 dividing the interior hollow portion into two sections, the inner one of which slidably receives a diametrically slotted hollow projection 39 which may be formed on a plate 40 secured to the side of the razor head. The manipulative member 3'7 is provided with a pin which may engage either of these slots in the projection 39 when one of the rollers is moved into cooperative position with respect to the razor blade. For the purpose of retaining the parts in position on the razor head I preferably employ a screw bolt 41 threaded into the plate 40 and which provides a seat for one end of the spring 42, the other end of which is seated against the partition 38 in the manipulative member 37.

When it is desired to move either roller into cooperative position with respect to the razor ll'il blade, the rollers are moved to the right, as indicated by broken lines in Fig. 5, by pulling on the manipulative member 37, after which the manipulative member is rotated 180 and the spring 42 is allowed to move the manipulative member inwardly, the pin in said manipulative member controlling the correct position of the rollers with respect to the edge of the razor blade. It is preferable, however, to allow for slight movement between the pin on said manipulative member and the slots on said projection on the plate in order that there may be a slight adjustment between the roller and the blade, as referred to in connection with the first modification described.

As shown in Figs. 8, 9, 10 and 11, the honing roller 30 is preferably provided with a single continuous helix comprising a single coil 44. This roller may be made of any suitable material, such as bakelite, molded on to a core or sleeve which is preferably roughened, as is indicated at 46, to prevent relatively longitudinal and rotational movement between the roller and the sleeve. The end of the sleeve may be provided with a notch, as indicated, by means of which the roller may be rotated for the purposes of grinding or smoothing its surface, if this should become necessary. As shown in Fig. 11, the outer face of the rib may be straight, in which case the edges of the rib operate as honing surfaces, as indicated.

If desired, the rib may be made of the shape shown at 30a in Fig. 12 in which the central portion of the rib operates as a honing surface under greater pressure than the lateral portions, the operation of said lateral surfaces having a stropping effect.

The use of a single helical rib comprising a single coil insures a honing operation at each point along the edge of the razor blade, this operation being facilitated by the pivoted roller support.

While the invention has been described in detail with respect to preferred examples thereof which give satisfactory results, it will be understood by those skilled in the art after understanding this invention, that various changes and modifications may be made without departing from the spirit of this invention and it is intended therefore in the appended claims to cover all such changes and modifications.
