This invention relates to safety razors and has for its primary object the provision of a frame, comprising a handle and a holder, for pivotally supporting the blade for honing and stropping operations, and adapted to reeei ve a detachable guard plate for supporting the blade during the shaving operation.

Another object of the invention is the arrangement of a resilient clamp for detachably securing the blades in correct position for honing. stropping and shaving, the clamp being mounted upon a pivoted carrier adapted to engage the surface of a hone or strop and guide the blade for eitlcient sharpening, the carrier holding the clamp at an angle rendering it possible to strop the blade upon a soft leather strop with the edge of the blade 'l'oremost against the strop the same as in honing.

A further object of the invention is the provision of a detachable guard member adapted to lit over the blade and be secured upon the frame in varying positions to control the angular relation of the blade to the handle.

A further object of the invention is the provision of a guard member having means for adjustably controlling the clearance space between the blade edge and the adjacent surface of the central teeth of the guard member;

whereby the closeness with which the razor will shave may be varied at will.

A further object of my invention is the provision of a guard member which may be very quickly and easily attached to and detached from the luade by means of resilient portions of said guard adapted to frictionally engage about portions of the blade and its supporting clamp when manually placed thereon, without thereby interfering with the free rotatability of the blade about its axis of support, said guard also having means for adju'stably connecting it with the frame at a point spaced from the axis of the blade, whereby said adjustment will. move the blade and guard about their common axis.

Other objects and advantages will be apparent from the following description wherein reference made to the accompanying drawings illustrating preferred embodiments of my invention, and wherein similar reference numerals designate similar parts throughout the several views.

Figure XIX is a plan view from above, of the top of the razor with the blade and bladeclamp removed, intended to bring out particularly the construction of the guard teeth in the adjustable embodiment of my invention, and the relation of the central to the endmost teeth.

Referring now to the drawings, the numeral 5 designates a handle and 6 a holder rigidly secured thereto in any expedient manner, as by the threaded stem 7, the whole comprising the frame. The holder is substantially U- shaped and provided with threaded apertures 6 adjacent the ends of its tines for the reception of fulcrum screws 8 (see Figure VI), the inner extremities of the fulcrum screws being rounded and adapted to fit Within the apertured ends of the blade carrier 9 to permit ready rotation of the carrier, as herein after described. Encircling the carrier 9 is a clamp 10 of resilient metal, the ends of which extend radially from the carrier 9 and are adapted to securely hold a razor blade 11 during the honing or stropping operations as well as during the shaving operation. To co-operate with blades that have notches adjacent their side edges, as do many of the single edged blades now in general use, I preferably form the clamping jaws 10 of the clamp with inturned projecting portions adjacent their sides, (see Figures III and VII) the projecting portions fitting within the notches of the blade and serving to position the blade within the clamp. This pre vents accidental movement of the blade within the clamp, and renders it easy to recognize when the blade is correctly positioned. Upon the ends of the carrier 9 are provided cylindrical nuts 12 (note Figure VI) which serve the purpose of retaining the clamp 10 in correct position upon the carrier 9 and also serve to provide a. broader tractive surface upon the strop or hone.

The external diameter common to both the clamp 10 and the cylindrical nuts 12 is so related to the blade carried in the clamp 10, that if a line or plane were extended from the beveled cutting edge of the blade, back as a continuation thereof toward the clamp, the projected line or plane would be precisely tangent the periphery of the clamp and/or of the cylindrical nuts. Thus when resting upon the surface of a hone or strop the beveled edge of the blade lies fiat thereon, while the surface of the strop or hone represents the projected extension of the beveled edge above referred to, and is tangent to the periphery of the clamp and nuts. By virtue of this construction it is possible to move the blade over the surface of the hone or strep with its edge foremost without cutting the strop or hone, even though flexible strops be used.

This is the correct position for sharpening razor blades and has been heretofore used in honing, but never in strapping, owing to the difficulty of moving a razor blade edge foremost over a flexible strop without cutting into the surface of the etrop. The beveled edges of razor blades are ordinarily slanted substantially equally from the sides of the blade, and with such blades the movement of the blade over the strop or hone can be made in either direction.

The operation of honing or stropping would accordingly be carried out by merely resting the carrier upon the surface of the hone or strop, which is preferably kept in a substantially horizontal position, and the frame alternately pushed and pulled by pressure on the handle 5. The first movement of the carrier upon the surface of the hone or strop serves to turn the clamp and blade to bring the beveled edge of the blade into frictional contact with the hone or strop. This position is then maintained during the remainder of the stroke in one direction, the friction of the carrier against the strop or hone serving to maintain the edge of the blade in close contact with the surface. As soon as the handle is moved in the opposite direction the friction on the periphery of the carrier serves to rotate the clamp and blade until the opposite side of the beveled edge of the blade is in frictional contact with the strop or hone, whereupon further movement in that direction may be made with the beveled edge in engagement with the surface. These alternate movements over the strep or hone can be continued as long as desired.

The blade can now be used for shaving without detaching it from the clamp 10, by the positioning of a guard structure substantially as shown in Figures I to V. The guard structure in the form there illustrated, comprises a guard member 14 having rounded and downturned teeth 15 at one end, and a securing member 13 of resilient material adapted to snap into position against the clamp and the inner face of the holder 6. The guard member 14,- and securing member 13 are preferably welded or otherwise suitably united so as to form a substantially integral piece. The angle at which the blade 11 is held relatively to the handle 5 may be adjusted in various ways to suit the convenience, but in this instance I have shown a plurality of aligned apertures 17 and 17 in the securing member 13, the central apertures 17 being adapted to fit over the threaded stem 7 of the handle 5, and the side apertures being adapted to it over studs 16 extending from the inner surface of the holder 6, substantially as shown in Figures I and V. The endmost guard teeth 15 are preferably bent upwardly and over the sides of the blade to serve in positioning the blade upon the guard member and aid the projecting portions of the clamping jaws in preventing lateral movement of the blade within the clamp. The free extremity of the securing member 13 is preferably curved to facilitate the posi tioning of the guard structure within the holder.

In Figures VIII to XI inclusive is shown a slightly modified embodiment of the guard structure whereby the razor blade is positioned within the frame for shaving. This form of guard structure comprises substantially the same guard member 14 welded or otherwise secured to a metallic strip 130 curved at its upper extremity to snugly fit over the clamp, and formed with apertured cars 1531 for the reception of a pivot pin 132 upon which is pivot-ally connected a positioning strip 133 by apertured ears 134. A coil spring 135 is mounted upon the pivot pin 132 with its ends engaging the strips 130 and 133 respectively to normally force them apart. The positioning strip 133 is provided with a plurality of spaced aligned openings 136 for adjustment relatively to the holder 6. As illustrated in Figure XI the adjusting openings 136 may be arranged adjacent each side of the strip 133 to co-operate with pins 137 on the holder, a central slot 138 being utilized to enable adjustment relatively to the threaded stem 7 whereby the handle 5 secured to the holder.

In Figures XII to XIV inclusive is shown an embodiment of the invention whereby double edged blades of the Gillette type may be employed. Substantially the same frame, guard member and carrier are employed as illustrated in Figures I to VII inclusive, but the clamp is formed with one of its jaws 101 of greater length than the other jaw and provided with spaced raised portions 102 to fit within the apertures in the blade 103. The raised portions 102 correctly position the blade 103 within the clamp and are spaced a sufficient distance from the carrier 9'to prevent the edge of the blade within the clamp from contacting the carrier.

The portion of the guard member comprising the central teeth 15 is preferably arranged parallel with the blade adjacent the cutting edge thereof and in spaced relation thereto, as is clearly shown in the enlarged Figure XVII, thereby providing a slight clearance space between the blade and the adjacent surface of said teeth. If desired, provision may be made for slightly moving the blade toward or away from the central teeth of the guard member, thus varying the extent of this clearance space to suit the preference of the user. This may be accomplished in various ways. but in Figures XV to XVIII I have shown means for adjustably warping or flexing portions of the guard member, thereby causing movement of the cutting edge of the blade relatively to the guard in a direction substantially perpendicular to the adjacent surface of the central teeth of the guard member, thus varying the extent of the clearance space between them. For this purpose, the guard member is preferably made of resilient material, and is designed in such manner that a line of cleavage is established be tween the endnio-st teeth 15 and the central portion of the guard carrying the teeth 15. asshown in Figure XIX; thus the endmost teeth constitute arms which may be flexed or warped relatively to the central portion of the guard. 'To this end the arms carrying the cndmost guard teeth 15 are provided with downturned apertured ears 150 for the reception of the stub shaft 151 on which are eccentrically mounted the adjusting members or rollers 152, which constitute in effect enlarged portions of the stub-shaft and which. obviously, if preferred, might be formed as a single member or roller which might be positioned near the center or run substantially the entire length of the stub-shaft. These members are preferably constructed with a plurality of like faces spaced at different distances from the stub shaft 151, whereby, when the several faces are brought into contactwith the lower surface of the central portion of the guard carrying the teeth 15, the endas most teeth 15 are flexed relatively thereto, substantially as shown in Figure XVII, the flexing 9f the endmost teeth serving to move the blade slightly about its pivotal mounting on the carrier, thus increasing or decreasing, as the case may be, the clearance space hetween the'cutting edge of the blade and the adjacent surface of the central teeth 15 of the guard member. It will be understood that the arms carrying the cndmost teeth 15 are normally flexed beyond or above the position corresponding to the least elfective face of the members 152, that is, the face of the adjusting rollers 152 nearest the center of the stub-shaft, so that the resiliency of the arms will hold the members 152 firmly in contact with the underneath surface of the guard member. A knurled handle 153 is provided for ready rotation of the adjustinginember 152. The adjusting device is carried by the guard member 14 and may be removed with the guard member when it is desired to strop or hone the blade. While this construction as herein shown may be considered as a preferred form, similar results may be satisfactorily obtained with other forms without departing from the principle of warping a portion of the guard member to vary the clearance space between the blade edge and the central teeth of the guard member. After the desired adjustment of the clearance space between the cutting edge of the blade and the central guard teeth is once secured it may be held indefinitely, even though new blades be utilized with the guard member.

While it will be apparent that the illustrated embodiments of my invention herein disclosed are Well calculated to adequately fulfill the objects and advantages primarily stated, it is to be understood that the invention is susceptible to variation, modification and change Within the spirit and scope of the subjoined claims.
