MEANS FOR MAINTAINING THE CUTTING EDGES OF SAFETY RAZOR BLADES Filed June 21. 1927 a j h ja Patented Apr. 19, 1932 UNITED STATES PATENT GFFIE MEANS FOR MAINTAINING THE CUTTING- EDGES OF SAFETY RAZOR BLADES Application filed June 21, 1927, Serial No. 200,441, and. in Great Britain September 15, 1926.
This invention relates to a means for maintaining the cutting edges of safety razor blades of the wafer type, for instance, that known under the registered trade mark Gillette.
Blades of this type very rapidly become dull or blunt, owing to the steel particles forming its edges becoming interlocked, twisted or bent in the process of shaving. This bluntness necessitates frequent stropping and honing the blades.
The object of my invention is to obviate this frequent stropping and honing, and to this end I employ a magnet, preferably a permanent magnet, shaped substantially like the letter C, having the terminal portions of the pole pieces extending inwardly in op posite directions, and provided with the opposed end faces substantially perpendicular to the terminal portions of the pole pieces between which the razor blade to be treated is placed, the said pole-pieces being at such a distance apart that the cutting edges of the blade are almost in contact with them. By this means, I find that the magnetic effect to which the edges of the blade are subjected, restores them to good cutting condition.
It is necessary to determine the correct position of the blade which may be for example of the Gillette type, with respect to the pole pieces so that the cutting edges of the blade shall occupy the proper position with regard to the opposed end faces of the terminal portions of the pole pieces of the magnet. It is preferable that one pole-piece of the magnet and one edge of each blade should be distinctly marked so that the blades may be placed always in position on the magnet, with the same edge to the same pole-piece.
To obviate the necessity of taking a safety razor of the described type to pieces when requiring to restore the cutting edges of the blade, I place the whole razor with the blade clamp resting on the base or back of the magnet in such a position that the razor guard, which is usually serrated, is lodged between and against the magnet pole-pieces, so that each edge of the blade is brought into the proper position between the opposed end faces of the terminal portions of the said pole-pieces.
To maintain the blade in this position, I preferably form rims, studs or the like on the upper part off-the pole-pieces so that the razor guard fits below them. This construction necessitates the engagement of the said guard with the magnet pole-pieces by movement through either end of the gap between the said pole-pieces.
To enable the invention to be fully understood I will describe it by reference to the accompanying drawing in which the single figure shows one form of a device in accordance with my invention for maintaining or restoring the cutting edges of safety razor blades of the Gillette or perforated wafer type, adapted for the reception of a complete safety razor.
Referring to the drawing, a indicates the base or body of the magnet which is substantially of C-form provided with perpendicularly disposed pole portions, a, a, having terminal portions, (0 a extending inwardly toward each other from portions, a, a, and provided with opposed end faces, Z), 6, which are spaced a distance apart slightly greater than the width of the blade to be treated, in this instance a Gillette blade, said faces being disposed substantially perpendicular to the edges of the blade adjacent thereto. Rims, g, g, are formed on the opposed end faces, Z), 6, of the pole pieces beneath which the edges of the usual serrated guard, 72,, of the razor or blade holder. G, fit by movement through either end of the gap between the end faces of the said pole pieces, the clamp, 2', of the razor or blade holder resting on the base or body portion of the magnet. In this arrangement, owing to the slight curvature imparted to the blade f, by the clamp 2', the end faces I), b of the polepieces are relatively inclined so that each is substantially at right angles to the adj acent edge of the blade 7, when in position between the end faces of said pole-pieces.
Claims 1. A device for maintaining or restoring the cutting edges of safety razor blades of the Gillette or wafer type, comprising a magthe terminal portions of said net having its pole pieces provided with terminal portions extending inwardly toward each other and having opposed end faces, separated at a distance slightly greater than the width of the blade to be treated, the terminal portions of the pole pieces being provided with guard engaging portions for engaging a razor guard and holding a blade in operative engagement with said guard, in position to present the opposite edges of the blade in proper relative position with respect to the said end faces of the pole pieces.
2. A device for maintaining or restoring the cutting edges of safety razor blades of the Gillette or wafer type, comprising a magnet having its pole pieces provided with terminal portions extending inwardly toward each other and havingopposed end faces, separated at a distance slightly greater than the width of the blade to be treated,
pole pieces being provided with inwardly extending projections to engage a razor guard having a blade in operative relation thereto, and hold said guard between said projections and the inner face of the body of the magnet, with the opposite edges of the blade in proper relative position With respect to the said opposed end faces of the pole pieces.
