SAFETY-RAZOR..

Specification of' Letters Patent.

Patented Jan. 22, 1907.

Application filed January 17, 1905. Serial No. 241,446.

To all whom, it may concern:

Be it known that I, CHARLES F. SMITH, a citizen of the United States, residing at New Britain, Hartford county, and State of Connecticut, have invented certain new and useful Improvements in Safety-Razors, of which the following is a full, clear, and exact descri tion.

lV y invention relates to'razors, and particularly to safety-razors.

Among the objects of my invention are simplicity of form and economy of manufacture.

Anotherobject of my invention is to so connect the operating-handle to the bladesupportthat the blade may be employed after the manner of the ordinary razor-blade, which permits the use of the desirable drawstroke."

In the drawings, Figure 1 is a perspectivev view of my invention. Fig. 2 is a longitudinal sectional view. Fig. 3 is a cross-sectional view. Figs. 4, 5, and 6 are plan views of detached details: l

1 is a base having securely connected thereto atl one end edge a handle 6. This handle 6 is arranged in a plane fparallel to the plane of the base 1, but is pre e the same. To that end I have provided an u turned connecting-piece 1b at one end edge ofJ said base. The opposite. end of the b ase 1 may also be raised, as at 1a, to provide a rounded end. Between these raised ortions 1a and 1b is located a blade 3, W 'ch preferably has clearance recesses or notches in the ends thereof to permit the blade to .be of `the greatestpossible length relatively to the base 1. The blade 3 maybe sharpened at one or both edges and overstands the adjacent edges of the base 1. 4 is a spring arra ed to rest on top` of the blade.' 5 -is a bac 'ng member resting above the sprin .'4.

.Thfe length ofthebacking member prefere IY corresponds to the length of the blade 3. Mounted on the base 1 is a stump 2, screwthreaded and provided with a thumb-nut 2a. The blade 3, s ring 4, and backing-plateI 5 should obvious y be perforated to permit the passage of the stump 2.v -The op osite edges of the backing member 5, which ie adjacent to theshar ened edge. or edges of the blade 3, are note ed or recessed to form tongues 5a. These tongues project beyond the edge rably elevated above or edges of the blade 3 toY act as guards. The blade 3 rests upon the'base 1, and the latter is immovable relatively thereto .when the parts are assembled. The backing member 5, however, may be raised or lowered to any desired extent, so that the guards .5a will stand nearer to or farther fromthe cutting edge or edges of the blade, whereby the operative cutting angle of the blade relatively -to the face of the user may be varied at will.

The spring 4 performs the double function of holding the blade 3 firmly down toits seat on the base 1 and of holdin the backing member 5 firmly up against t 1e under side of the adjusting thumb-nut 2a in its various ositions of adjustment. To prevent disp acement of the parts, the lower side of the backihg member 5 may be recessed to a width vcorresponding to the width of the spring 4, as

best seen vin Figs. 1, 2, and 3. When the s ring stands in this recess, its longitudinal alinement with the backing member is preserved. This also permits the backing member to be moved down into closer proximity tothe blade 3. i

In'the foregoing it will be seen that the user may grasp the handle 6, and the latter, being elevated relatively to the base 1, will afford sufficient space between said handle and the face to prevent the fingers of the user from interfering with the free actionr'of'l the instrument.

By means of the foregoing arrangement thel user may readily remove the. blade for the purpose of honin or for the purpose of permitting another b adeto be substituted. By havingl the handle arranged longitudinallyof t e base and'by having theblade two-edged the instrument may be used with either hand with equal facility.`

I am aware, of course, t at .two-edged:

blades have been known Ifor many years,and therefore make no claim of novelty .to this feature broadly. y 'us' a two-edged blade in a safety-razor proied with mynew handle -a new and useful combination results. The instrument may be `used with either hand, and the work is necessarily divided e ually between the' two sharpened ed es, w ereby one edge will not become du led unduly in advance of the other.

. 'Ehe base v1 has on its lowe'rside a smooth and vunbroken bearing-surface .with the.

edges'and ends rounded, so that the instrument maybe applied to the face at any angle Without danger of injury thereto.

What I claim is-- 1. A safety-razor comprising a base member having a smooth bearing area with substantially parallel edges, a handle rigidly secured to said base member extending lon itudinally thereof and in a line substantia ly parallel with the edges of said base member, a detachable backing member having guardteeth on its opposite edges, and having a central perforation and a screw stump or post passing through said perforation and secured to said base member, and provided With an adjusting-nut, the axis of said stump being substant1ally at right angles to the axis of the i handle.A

2. In a device of the character described, a supporting-base having a smooth unbrbken contact or bearing surface on its lower side, a blade supported on the upper side thereof, one edge of said blade projecting beyond one side edge of said supporting-base,"1neans for holding said blade in place comprising an independently-movable 'backing member -arranged above said blade and a spring arranged between said backing member and said blade, and a handle connected to one end edge of said base and projecting longitudinally thereof.

3. In a device of the character describedl a base having a smooth unbroken bearing or contact` surface on its lower side, a blade supported on the upper side of said base, one edge of said blade `projf'ecting beyond one side edge of said base, a backing member arranged above said blade, a spring arranged between said backing member and said blade, means for adjusting said backing member relatively to said blade, guard-tongues carried by'said backing member at one edge thereof and overstanding the sharpened edge of the blade, and a handle secured to said base at one end edge thereof and arranged to project longitudinally of said base. f

4. I n a device of the character described, a base havin a lsmooth rounded bearing or contact su ace on its lower side, a blade supported upon the upper side, the opposite edges of said blade being sharpened and projecting beyond the side edges of said base, an

` adjustable backing member arranged above said blade, a spring arranged between said blade and said backing member, guardn tongues arranged at each edge of said backing member and overstandingboth edges of said blade and a handle secured to one end edge of said base and thereof.

5. In a safety-razor, a base, a blade, auletachable backing member, a stump passing projecting longitud inally clamp-nut therefor, an upturned portion at one end of said base, a handle secured to said upturned portion, the axis of the handle extendinglongitudinally of the base and in' a plane above the base and said blade.

In a safety-razor, a base, a blade, a detachable backing member, `a stump passing through said blade and backing member, a clamp-nut therefor, an upturned portion at one end of said base, a-handle connected thereto, the-axis of said handle being arranged in a plane above said base and blade and parallel thereto.

7. VA safety-razor comprising a base member having a smooth bearing area and substantially parallel opposite edges, a handle member secured rigldly to one end of said base member, and extending longitudinally i therefrom, with its axis substantially parallel to the edges of said base member, a blade centered and supported on said base member having oppositely-disposed cutting edges, a detachable backing member having oppositely-disp'o'sed guard-teeth arranged along its edges and adjustable means independent of the handle for clamping said backing member to said base member.
