SAFETY RAZOR Filed March 11, 1946 2 SHEETS--SHEET 2 WTTO RNET Patented Oct. 23, 1951 UNITED STATES PATENT OFFICE" I SAFETY RAZOR. V William L. Mills, Waco, Tex. Application March 11, 1946, Serial No. 653,546 soiaiins. (or. 30-69) This invention relates to razors and more particularly to a safety razor including separable plates between which a blade is mounted and a handle threaded to a stem carried by one plate and passing through an opening in the other plate, it being one object of the invention to provide the razor with plates so formed that a narrow blade may be firmly clamped between the plates and prevented from slipping out of a position in which its cutting edge will be held parallel to front edges of the plates and also parallel to a bar constituting a portion of a guard which is pivoted to one plate and yieldably held against swinging movement so that it will assume a position allowing the blade to cut a beard while shaving but not cut a persons face.

Another object of the invention is to provide a safety razor wherein the blade has end tongues by means of which it may be readily held and inserted or removed from between the plates.

Another object of the invention is to so form the guard and so form one plate that swinging movement of the guard towards a protruding sharpened edge of the blade will be limited and the blade prevented from assuming an angle in which it may cut a persons face while shaving.

Another object of the invention is to provide the razor with a spring mounted longitudinally of the front plate with its ends projecting therefrom for engagement with arms of the guard to urge the guard towards the front plate.

Another object of the invention is to provide a safety razor consisting of plates and a handle so formed that while the razor may be taken apart for thorough cleaning and drying 'the plates will be firmly held together for clamping a blade between them when the handle is applied and screwed along the stem into contact with the front plate.

The invention is illustrated in the accompanylng drawings wherein:

The razor illustrated in Figures 1 through 9 has a front plate I, a rear plate 2, and a handle 3 which is screwed upon a threaded stem 4 carried by the rear plate 2 and removably engaged through an opening 5 formed midway the length of the front plate I. The rear plate 2 also carries pins 6 located near its end and passing through openings 1 formed in thefront plate. Ends of the pins are upset to limit movement of the plate 2 away from the plate I, but the pins are of such length that plate 2 may be shifted away from the plate i when the handle is loosened upon the stem 3 and thus provide space between the two plates. The lower edge portion of the front plate is smooth and at its ends this plate is provided with tongues or fingers 8 which project downwardly and are of such length that they project beyond the sharpened edge of a blade 9 when the blade is fitted into the space between the plates and the handle then tightened upon the stem 3 to move the plate 2 towards the plate I and into clamping engagement with the blade. This blade 9 is formed as shown in Figure 9 and has its rear edge formed with recesses H] and II to receive the stem 4 and the pins 6 which serve to prevent the blade from slipping longitudinally out of its proper position between the plates. This also assures parallel relation of the cutting edge of the blade with lower edges ofthe plates and causesthe sharpened edge of the blade to protrude from the plates the same distance throughout its length. Tongues l2 project from ends of the blade and are of such length that they protrude from ends of the two plates; Therefore the blade may be held by its tongues l2 and readily slid into place between the plates, and by grasping these tongues a blade may be easily withdrawn from between the plates.

In order to prevent the blade from cutting a 3 persons face while shaving there has been provided a guard I3 consisting of a bar of stiff metal having arms M at its ends. The bar 13 is of greater length than the plates and its arms I4 of such length that pins l5 projecting from ends of the upper edge of the front plate I may engage through openings formed in the arms and pivotally mount the guard for swinging movement from the position shown in full lines in Figure 1 towards the -p'osition indicated by dotted lines. The tongues B and the tongues l2 overlap the upper faces of the bar and the arms of the guard and serve to limit rearward swinging movement of the guard beyond the position shown full lines in Figure 12. In order to normally hold the guard in abutting engagement with the tongues 8 and I2 and yieldably resist forward-'m'ovement plate I 'and'exteriding longitudinally thereofwith its free'end portions 16' projecting from ends of this plate and extending across the armsef-the guard as shown in Figure 3. The spring urges the guard rearwardly but allows it to'be swung forwardly. Therefore whenthe raz'or is in use the guard and the blade may havemove'inent'relative to each other and the blade maybe disposedin such an- 'angularly adjusted position that its sharp edge may cut through whiskers withoutcutting a persons face while shaving. When the handle is unscrewed from the stem 4 the "plates-may be separated and the blade removed so that therazor may be thoroughly cleaned and'drie'd and then reassembled. v

In Figures through 18 there has beer'rillustrated' a modified construction. In this embodiment of'the-invent'ion the front and rear plates H and I8 clamp a blade I9 between them with tongues 20 of the blade projecting frem ends of the plates and the sharpened edge of the blade projecting from the teeth 2| alongthefront edge of the platel8 between the tongues 22. A recess 23 is formed'm'idway the length of the rear edge of the blade to receive a portion 'of the stem or post 24 which is carried by the plate [8' and passes through the opening 25 of front plate I! for engagement inthe threaded socket of the handle 26. A rib 28 formed along the inner face of the plate lflengages in a groove 29 formed in the'inner face of the plate I! and'serves to hold the two plates against turning movement about the post. The rear edge of the blade bears against the rib and-causes the blade to be held against tilting and maintains its sharpenededge parallelto frontedges of the plates.

A'guard'is-pr'ovidedto prevent cutting of a ersons face due to improper engagement 'o'f'ithe sharpened edge of the'b'lade with the skin. This guard 30 consists of a bar of stiff metal whichfis of greater length than the jaws or plates 11 and I8 and is formed at its ends with arms 3i having openings near their ends to receive the pins 32 at ends of the plate I! and pivotally mount the guard for swinging movement from the position shown in full lines in Figure 11 towards the position indicated by'dotted lines. This guard isto bear against the skin while'sh' ving and serve'as a-fulcrum across which-the razoris'ro'cked ta dis'-' pose the blade'in proper angular relation to the skin so that it may cut the beard without cutting the skin. It is necessary that the guardbe urged to the position shown in full linesin-Figures' 1'1 and 13 but allowed to swing'about th'e pins -32 during use. of the razor and-in order to urge-the thoroughly cleaned and dried and then reassembled for use.
