Robert W. McGarvey, of Sparrows Point, Maryland. Safety Razor.
1,418,191. Specification of Letters Patent. Patented May 30, 1922.
Application filed November 7, 1919. Serial No. 336,349

To all whom it may concern:

Be it known that I, Robert W. McGarvey, a citizen of the United States, and residing at Sparrows Point, Baltimore County, State of Maryland, have invented certain new and useful Improvements in Safety Razors, of which the following is a specification.

Numerous attempts have heretofore been made to provide a safety guard for razors which is as efficient in operation as the old-fashioned unguarded razor and which has at the same time the additional features of increased safety to the user, decreased bulk and cheapness. The general objects of this invention are to produce a razor which is simple, may be rapidly and easily stropped, and which allows a perfect control of the cutting edge of the razor in shaving.

The present invention provides a safety razor which has all the advantages of the unguarded razor and many advantages not realized by safety razors which have heretofore been constructed. It is simple, the blades may be easily stropped in the holder by even an inexperienced operator, and there is little danger of the strop being cut, the blades are quickly insertable and removable, a perfect control on the cutting edge is realized by the operator in shaving, and by the provision of two blades in the holder instead of a single blade the razor is rendered particularly useful to persons having tough beards who ordinarily must stop to replace a blade in the guard or holder before completing a shave, due to the fact that the first blade has become dull. The design of the frame or holder of this razor is such that in shaving it is gripped over a flat surface with the finger tips almost at the cutting edge of the blade, allowing a cutting stroke that cannot be equaled with safety by any other razor, especially razors having long handles giving a long leverage.

The blades can be not only conveniently stropped when in the holder but can be honed without removal therefrom simply by working them over a honing stone, and neither in stropping or honing is the skill required which is necessary in sharpening the old straight unguarded blade razor. One embodiment of the invention is disclosed by way of example in the following description when taken in connection with the accompanying drawings in which:

Figure 1 is a top plan view of the safety razor;

Figure 2 is an end elevation of the same;

Figure 3 is a section along 3—3 of Figure 1;

Figure 4 is a perspective view showing one of the blades in cutting position and one in stropping position;

Figure 5 is a side view of the razor in stropping position in the hand of a user;

Figure 6 illustrates the manner in which the razor is grasped for shaving.

The frame of the razor comprises two similar plates 10 disposed at substantially a right angle to each other, and suitably secured together or formed integral, the common edge of the two plates forming the safety guard 11, which is toothed or serrated in the usual manner. Each of the plates 10 is cut away at 12 leaving a tongue or bar 13 on either side of this recess. A bar 14 slotted at its ends to fit around guide bars 13 of each plate 10 is slidably mounted thereon parallel to the safety guard 11, and projections 10a on the outer ends of guide bars 13 prevent the bar 14 from slipping off. Journaled on each of the bars 14 is a razor blade carrying member 15.

Each member is rotatable around one of the bars 14 and is adapted to hold between its two parallel side portions 15a and 15b the razor blade 16. The razor blades are notched at 17 at their opposite ends and into these notches the lugs 18, which are integral with portions 15b of the members 15, are adapted to enter to prevent the blade from slipping from the holder. The portion 15a of the member 15 in reality comprises a latch cooperating with the edge 10b of the plate 10 to hold the blade carrying member 15 with the blade held thereby, in position for shaving. In Figures 2 and 3 the razor blades and their supporting members 15 are shown in shaving position with the blades lying flat against the plates 10 and firmly held in such position by latches 15a which have slipped over and engaged the edges 10b of the plates 10, the members 15 being made of springy material, and the parts will remain in this position until the bars 14 have been pulled outwardly, disengaging members 15a and 10b and rendering the blade holding portions free to rotate through an angle of 180°, about the bars 14. Projections 19 of small size are also provided on the guide members 13 and the sliding bars 14 must be forcibly moved over these stops in shifting from one position to another.

In inserting the blade into member 15 its ends must be bent upwardly somewhat to bring the notches 17 into engagement with the lugs 18, and in removing the same one end must be bent until the notch has been disengaged from the lug 18.

In Figure 4 the razor is shown with one blade in stropping position except that the bar 14 has been moved downwardly along guides 13 to show the stops 20. These stops 20 serve to position the blade in both stropping and shaving as, in performing either function, the bar 14 is moved upwardly (Figure 4) until it reaches the position indicated by the dotted line, the shoulders 20 preventing further movement and determining the relative positions of the edge of the blade and the guard edge 11. In stropping, however, the blade is free to rotate through nearly 180° about the bar 14, the motion in one direction being limited by the member 15a striking the plate 10 and in the other direction by the ends of the member 15b striking the outer ends of the guide bars 13. In Figure 5 the razor is shown positioned on a strop S and the operator's fingers in proper position. When at the end of the stroke the blade is quickly rotated about the bar 14 into position (doubled under plate 10) for a return stroke, by exerting a small tangential force with the middle finger of the hand on the rounded part of member 15. As the razor is being drawn along the strop a considerable downward pressure is exerted by the hand and the rounded part of member 15 and the edge of the blade are tightly pressed against the strop. The blade may be honed when in the same position and without removing the same from the holder.

In Figure 6 the manner of holding the razor when shaving is illustrated. Here the vertical blade is the cutting blade and the horizontal blade holding portion serves as a handle. It should be noted that the operator's fingers are within a very short distance of the cutting edge of the razor whereby the “feel” of the operator is rendered more sensitive and the liability of his cutting or scraping his face greatly decreased. The frame is preferably stamped from sheet metal, and also the blade holding members, but other material may be utilized if desired. Obviously many changes and alterations in the specific features of the invention may be made and I do not limit myself to the exact embodiment described and illustrated.
