To all whom it may concern:
Be it known that I, James Hartness, of Springfield, in the county of Windsor and State of Vermont, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.
This invention has relation to safety-razors, and has for its object to provide certain improvements therein, among which may be noted the following:
One of the primary objects of the invention is to provide a safety-razor with a miniature blade which may be used so long as it is sharp or keen, and then discarded and thrown away. Preferably, the blade is made of wire. Instead of being formed of sheet metal, the blade, while extremely small in cross-section, is so constructed as to be as rigid as possible, said blade having faces converging at the proper angle to form a sharp cutting edge.
Another object of the invention is to provide certain improvements by means of which the blade may be clamped to a suitable holder, and to leave sufficient clearance for the reception of lather when the razor is in use. This is accomplished, in the present embodiment of the invention, by so forming the clamp that a space is left adjacent the projecting edge of the blade. The clamp in said embodiment is constructed to coöperate with the handle of the razor, so that by moving the handle, the clamp member may be locked in position or unlocked, as desired.
Referring to the accompanying drawings, which illustrate one embodiment of the invention,—
The holder comprises a base member
The blade itself, as previously stated, is made of wire. It is very small in size, being not more than one eighth of an inch wide and one sixteenth of an inch, or less, thick, at its back. The two faces
The base member a may have the approximate shape of a triangle, as shown in
It will be seen from
The movable clamp
It will be noted from
By reason of the construction thus illustrated and described, the base member, the handle, and the blade may all be easily detached by rocking the handle to the dotted position
It should be noted that since the beveled front wall
The parts are all designed to fit accurately together, so that the blade will be held tightly in upright position relatively to the base member and against the backing
The flange or backing
It will be apparent that the razor as a whole is of the simplest possible construction and possesses the smallest possible number of parts.
The terms “upper,” “under,” “rear,” “front,” “inner,” “outer,” “lower,” etc. are relative, and I use them in no limiting sense, but simply to aid in the description of the razor,
Having thus explained the nature of the invention, and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the modes, of its use, I declare that what I claim is:—
1. A normally flexible blade wedge-shaped in cross-section.
2. A normally flexible blade of drawn steel wedge-shaped in cross-section.
3. The combination with a normally flexible blade wedge-shaped in cross-section, of a holder having clamping members for stiffening said blade for use.
4. A safety razor comprising a holder having a base member, a blade standing upright therefrom, and clamping members for holding said blade in upright position relatively to said base member, one of said clamping members having a guard or comb.
5. A safety-razor comprising a holder with a substantially flat base member having an upturned end to form a backing, a clamp resting upon the face of said base member and having a wall opposing the backing, and a blade interposed between the said wall and the said backing.
6. A safety razor comprising a substantially flat base member, a blade having its back bearing against the face of the base member and standing upright therefrom so that the edge projects at an angle to said face, and clamping means for engaging the faces of said blade and securing it to said base member.
7. A safety razor comprising a holder with a base member having a projecting flange for engaging the skin, a clamp opposing said flange and having a comb for engaging the skin, said comb and flange being separated to provide a lather receiving space, and a blade backed by the base member and secured in place by said flange and clamp, said blade having its edge projecting into said lather receiving space.
8. In a safety razor, a holder comprising a base member and clamp members having adjacent walls which form a substantially triangular space, one of the walls being movable to widen the space, and a normally flexible blade triangular in cross section adapted to be arranged in said space with its edge projecting outside of said space with a clearance adjacent both faces of the projecting edge.
9. In a safety razor, a holder having a base member provided with two walls at an angle, one for the back of the blade, and one for one face of the blade, a slidingly-supported clamp having a wall to engage the other face of the blade, and means for forcing the clamp towards both the said walls of the base member of the holder.
10. In a safety razor, a holder consisting of a base member having an upturned wall, a clamp slidingly supported on the base member and having a wall confronting the upturned wall, a blade adapted to be arranged between said walls with its back against said base member, and means for holding said clamp against said blade.
11. In a safety razor, a holder having a base member and clamp members provided with confronting converging walls at an angle to said base member, one of said clamp members being movable, a wedge-shaped blade adapted to be clamped between said walls, and a handle having means for positively moving and operating the clamp.
12. In a safety-razor, a holder comprising a base member and a clamp having confronting walls, a blade arranged between said walls and projecting therefrom at an angle to the said base member, and a guard on the clamp having its teeth recessed to form clearances between the rear of the blade and said teeth.
13. In a safety-razor, a holder comprising a flat plate having at its end a flange to provide a flat inner wall at an angle to its face, a blade adapted to be arranged in said angle with one face against said wall and to project beyond said flange, a flat clamp on the face of the holder having an outer wall to engage the other face of the blade, and a guard on the face of the said clamp.
14. In a safety razor, a holder having a base member and a fixed clamp member, a clamp slidingly supported on the base member, a blade between the two clamp members, and a rotatable handle having a cam for operating the slidingly-supported clamp.
15. In a safety-razor, a holder having a base member formed with a slot, a handle having a shouldered or flanged stud to project through said slot and to attach the holder thereto when the handle is rotated to normal position, and means for clamping a blade.
16. In a safety-razor, a holder having a base member formed with a slot, a handle having a shouldered or flanged stud to project through said slot and to attach the holder thereto when the handle is rotated to normal position, a clamp on the holder, and a cam on the handle for operating the clamp when said handle is in said normal position.
17. In a safety-razor, a holder having a base member formed with an upturned flange or backing, a blade, a clamp on the face of the holder, a handle adapted to be rotatively engaged with the base member with its axis of rotation transverse to the faces of the clamp and the holder, and means on the handle for operating the clamp and locking it in position on the holder.
18. In a safety-razor, a holder having a base member formed with an upturned flange, the inner wall of which forms, with the upper face of the holder, an acute angle, a clamp resting on said face and having a beveled front wall likewise at an acute angle to said face, a blade adapted to be inserted between said inner wall of the flange and the outer beveled wall of the clamp, and means adapted to engage the rear end of the clamp to force it toward the flange.
19. In a safety-razor, a holder having a base member, a blade, a handle adapted to be rotatively engaged with the base member and having a cam, a clamp for clamping the blade against the holder, said clamp having a spring arch adapted to be operatively engaged by said cam.
20. In a safety-razor, a holder having a base member and a clamp formed of plates, or sheet metal, with the under face of the clamp adapted to rest upon the upper face of the base member, said base member having a flange confronting the front end of the clamp, a blade adapted to be inserted between the clamp and the flange, and a handle adapted to be inserted through an aperture in the base member in the rear of the clamp, said handle having means for binding the clamp and base member together and for forcing the clamp operatively against said blade.
In testimony whereof I have affixed my signature, in presence of two witnesses.
