W. L. MILLS SAFETY RAZOR Nov. 14, 1944.

Filed March 16, 1944 gnaw/M300 W. L. HILLS Patented Nov. 14, 1944 UNITED STATES PATENT 1 OFFICE SAFETY: RAZOR l William L. Mills, Waco, Tex. Application March 1.6, 1944, Serial No. 526.72g I 6 Claims. (01. 30:-63)

This invention relates to ,a safety. razor and it is one object of the invention to provide a safety razor having a frame and embodying improved means for detachably holding a blade in engagement with the frame, said means consistfaces for engaging across the upper edge of the blade.

Another object of the invention is to provide" the razor with a guide roller rotatably mounted along the lower edge of the frame in cooperating relation to the sharpened edgeof a blade carried by the frame, the roller being rotatably mounted between arms carried by end flanges of the frame and spaced a predetermined distance from the cutting edge of the blade.

Another object of the invention is to provide a safety razor wherein the guide roller is rotatably carried by arms which straddle end flanges of the frame and are held to the flanges by bolts which create frictional binding between the flanges and inner and outer leaves of the arms and serve as pivots so that the armsmay be swung about the bolts to move the roller toward and away from the blade.

Another object of the invention is to provide a safety razor whichis simple in construction, capable of having a blade very easily applied or removed, and so formed that it may be quickly cleaned and its roller set in desired spaced relation to the blade.

The invention is illustrated in the accompanying drawing, wherein:

Fig. 1 is a side elevation of the improved safety razor.

Figure 2 is a front view thereof.

Figure 3 is a sectional view on the line 3-3 of Fig. 2.

Figure 4 is a top view of the safety razor.

Figure 5 is a fragmentary sectional view on the line 5-5 of Figure 4. I

This improved safety razor has a frame formed of metal or other suitable material'and having a front plate I which may be of double thickness, as shown in Fig. 3, or of single thickness. Flanges 2 and3' extend rearwardly along the upper edge andopposite ends of the front plate and, at its oppositeends, the front plate carries lips 4 which overlap the front face of the front plate in spaced relation thereto and are in such angular relation to the frame plate that when a blade 5 of the type which is sharpened along one edge is thrust into place, its end portions will have wedging fit between the front plate and the lips. This blade has its sharpened lower edge projecting from the front plate and, in

order to guide the blade when shaving, there has been provided a guide roller 6 which extends longitudinally .of the front plate downwardly therefrom and rotatably mounted between arms 1. These arms are formed from folded strips of sheet metal or other suitable material and each arm has inner and outer leaves 8 and 9 formed with alined openings l0 near their integrally united lower ends to rotatably receive pintles II at ends of the roller. The roller may be formed with a spirally extending rib I 2, as shown, or may be smooth. The leaves. of the arms are resilient and mounted at opposite'side faces of the end flanges 3 by bolts l3 which pass through alined openings formed in the flanges and the leaves, as shown in Fig. 5. Referring'to this figure, it will be seen that when the-nut of a bolt is tightened, the leaves-will be drawn toward the end flange and have frictional gripping engagement therewith. Threfore, by loosning the bolts, the arms may be swung about the bolts as pivots or slid along the bolts to move the roller toward or away from the loweredge of the front plate and dispose it inpredetermined spacedrelation to the cutting edge of the blade and after the roller has been disposed in the desired position, the bolts .may be tightened to firmly hold the arms in set position. This also permits, the roller to be thoroughly cleaned and, in addition, permits re.- moval of the roller from the arms if necessary.

A shank I4, formed of sheet metal and carrying a handle li, is fixedly carried by the upper flange 2 of the frame and, since the shank is located midway the width of the upper flange and extends rearwardly from the same at a downward incline, the handle may be conveniently held during use of the razor.

A post or stem l6 extends upwardly from the flange andshank midway the widthpf the upper,

flange and this post carries a blade fastener I! which is rotatable about the post. portion of the fastener is enlarged to form a turning head or foot l8, which projects from, opposite sides of the fastener and has flat sides so that it maybe readily grasped when'thefastener is to The lower I be turned to the operative position shown in the drawings or to an inoperative position at right angles to the operative position. The under face of the head or foot has its end portions curved longitudinally to form cam surfaces I9 and when the fastener is turned to-the operative position, one of these surfaces rests upon the upper surface of the shank while the other extends across the upper edge of the blade and exerts pressure to force the blade downwardly into tight wedging engagement with the lips 4. The blade will then be firmly held in place and the razor is then ready for use. If it is found that the roller is not in proper spaced relation to the cutting edge of the blade, the bolts l3 may be loosened, the arms 1 swung toan adjusted position, and the bolts tightened again to firmly hold the arms in the adjusted position.

Having thus described the invention, what is claimed is:

1. A safety razor comprising a frame having afront plate and flanges extendin rearwardly along the upper edge and opposite ends thereof, lips at opposite ends of said front plate overlapping the front face thereof, a blade disposed against the front face of said front plate with the ends fitting under said lips and. its lower sharpened edge projecting from the front plate, arms having inner and outer leaves extending longitudinally of the end flanges with the end flanges between their leaves and lower portions of the arms projecting from the flanges, a roller rotatably mounted between the projecting ends of the arms, bolts passing through the end flanges and upper portions of the arms to pivotally mount the arms and hold their leaves in frictional gripping engagement with the end flanges with the roller extending along the sharpened edge ofthe blade in desired parallel spaced relation thereto, a handle extending from the upper flange midway the width thereof, a portion extending upwardly midway the width of the upper flange, and a blade fastener rotatably mounted about said post and having a turning head at its lower end projecting, from the post in opposite directions and having under faces of its projecting portions formed with cam surfaces for extending forwardly and engagin across the upper edge of the blade to hold. the blade firmly in place when the fastener is turned about the post to operative position.
