Further detail objects of the invention will be apparent from the following specification and set forth in the appended claims.
In the drawings: Figure 1 is a perspective view of a well I known type of safety razor having my invention applied thereto. Figure 2 is a transverse section through the tame. Figures 3, 4, and
ing diflerent forms of rollers. v
Figure 6 is a fragmentary view showing a difierent means for holding the roller in position. v i
Figure 7 is a detail view showing the roller mounted in a support which is adjustably carried by the guard.
Figure 8 is a section on the line v8-8 of Figure 7. Figure 9 is a view showing a modified form of roller.
The invention is illustrated in Figure 1 as being applied to the well known Gillette safety razor, employing a double edged blade and therefore necessitating two rol ers, but itis to be understood that the invention is applicable to other forms of safety razors employing a single edged blade which necessitates only a single when It is to be understood, therefore, that the illustration is not to be regarded as limiting the invention in this respect.
There is shown a safety razor having the usual handle A, clamping member and guard plate C, the clamping member havin a projecting-arm D which is screw threade at its end to engage a screw threaded mem- 5 are detail views show i is provided her E carried by the handle A. The guard member is provided with theusual guide lugs F which pass through holes in the razor blade G and this latter is clamped between the member B and the guard C in the usual 'way. whatever may be the type of razor to which the invention'ls applied, there will be found members which correspond to the clamping member B and the guard member C. ,The guard member C is provided at its edge wlth serrations'l which lie slightly in the rear of the edge of the blade. At each sldethe guard is provided with outwardly extending lugs 2 in which is journaled a roller 3. This roller lies outside the ends of the serrations 1 and is of a size to project beyond the ends of the lugs-2.
This roller maybe of diderent forms. As
shown in Figures 6 and 7 and in one of the rollers of Figure 1, this maybe a simple cylindrical roller. As shown in the other guide roller of Figural and as indicated in Figure 3, the roller may have a spiral groove or grooves running from one end to the other. As indicated in Figure 4, these spiral grooves may run in opposite directions, thus providing the roller 5 with a plurality of diamond shaped projections upon its surface. As shown in Figure 5, the roller with a plurality of circumferential grooves 6, while Figure 9 shows a form in which the roller 15 may taper slightly from one end to the other.
The ends of the roller may be journalled in the lugs 2 in any desired manner and in general the roller will lie with its axis parallel to the edge of the razor blade. It has been found, however, that it is highly advantageous to place the roller with its axis at. a slight angle to the edge of therazor blade as indicated in Figure 3. In this form one of the lugs 2 is made somewhat longer than-the other so that the roller will lie at the desired angle. In using the razor the same will be naturally drawn across the face in a direction perpendicular to the axis of the roller and if the latter lies at an angle to the edge of the blade this .will produce the desired shearing out which is much more efiective than if the razor is moved directly at right angles to the edge of the blade. It will be found in this form of roller that it is also desirable to use the spiral "may be of the usual form as ures 5 to 7, but I prefer to construct these roller to the guard and in this case there is provided at each edge a spring'member.
7, one end of which is fastened to the guard by fastening means 8 of any desired character and the outer end 9 of which is enlarged and provided with a depression adapted to engage a pintle 10 on the end of the roller.
t is, of course, evident that any form of roller may be employed in this form and it is also apparent that one of the spring arms 7' may be .longer than the other in order to mount the roller with its axis at an angle to the edge of the blade.
In the modification shown in Figures 7 and 8 the lugs2 are omitted and the roller which may be of any desired form is journalled in arms 11 which are connected by a groove member 12 having an enlarged portion provided with. a slot 13 in which passes the screw 14 or similar fastening member. The'end of thisscrew is threaded into the guard member so that by loosening the screw, the position of the roller relative to the edge of the blade may be adjusted. Not only may the roller be brought closer to the edge of the blade, but by providing a slight lost motion at the edges, it is possible to adjust the roller so that its axis lies parallel with the edge of the blade or at an angle thereto.
The serrations on the guard member C shown in Figin the form shown at 1 in Figures 3 and 4. In this form the serrations lie almost entirely on the under side of the guard plate and are hardly visible upon a direct view of the top thereof. They lie in the rear of the edge of the plate and as indicated in Figures 3 and 4, there is a space between the edge of the blade and the guard roller. In this construction the serrations hold the lather and distribute it so that particularly when used in connection with a guard roller having a corrugated surface it is not necessary to apply fresh lather to the face when going over the same a second time.
It is found that a razor equipped with a roller of the type shown, particularly with the corrugated rollers 4 or 5, is very efficient as a massaging device and it therefore has the double auction of acting as a guard for the edge of the razor blade and massaging the flesh. over which it passes. Moreover,
rollers of this type tend to retain and distribute a portion of the lather when it is desired to pass the razor over any portion of the face a second time, thus avoiding the necessity of using additional lather when said second shave is desired. Particularly Where a roller 4 is mounted with its axis at an angle to the edge of the razor blade, it is found that the action of a razor thus equipped is very satisfactory In addition to acting as above described, the roller facilitates the movement of the razor and does not cause any scraping movement which tends to irritate the skin.
When the rollers of 'the types shown in Figures 4-, 5 and 6 are employed, it is found that the massaging effect is very appreciable and if desired the razor may be used without the blade as a simple massaging implement. When so used it has been found to be very efficient.
It is obvious that various detail changes may be made and that the invention may be applied to safety razors of widely va ing types without in any way departing rom the spirit of the invention, which is to be regarded as limited only by thescope of the appended claims. s
I claim as my invention:
1. In a safety razor, the combination with a guard having a serrated edge, of a blade mounted on said guard and having its cutting edge disposed forward of said serrated edge and in parallelism therewith, and a roller journaled on said guard and disposed in front of the cutting edge of the blade and in spaced relation to the serrated edge of the guard for cooperation therewith to retain lather.
2. In-a safety razor, the combination with a guard having a serrated edge, of a blade mounted on said guard and having its cutting edge disposed forward of said serrated edge and in parallelism therewith, and a spirally grooved roller journaled on said guard and disposed in front of the cutting edge of the blade and in spaced relation to the serrated edge of the guard for cooperation therewith to retain lather.
3. In a safety razor, the combination with a guard having a serrated edge, of a blade mounted on said guard and havin its cutting edge disposed forward of sai serrated edge and in parallelism therewith, and a roller journaled onsaid guard and disposed in front of the cutting edge of the blade and edge and in parallelism therewith, a. grooved frame adjustebl fitted over the serrated edge ortion of t e guard, a roller journaled on said frame and disposed in front of the cutting edge of the blade and in spaced relation to the serrated edge of the guard for cooperation therewith to retain lather, and
means for securing the frame to the guard whereby the roller maybe secured in any position of adjustment relative to the cut- 10 ting edge of said blade.
In testimony whereof, I have hereunto subscribed my name. 7
