To all whom it may concern:
Be it known that I, James T. McCann, a citizen of the United States of America, residing at Greensburg, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to safety-razors; and its primary object is to provide a device of this character of simple and inexpensive construction in which the corners of the razor-blade as well as the cutting edges thereof are protected to prevent injury to the user.
A further object of the invention is to provide a safety-razor the parts of which may be readily assembled or taken apart.
The construction of the improvement will be fully described hereinafter in connection with the accompanying drawings, which form part of this specification, and its novel features will be set forth in the appended claims.
In the drawings,
The central portion
The end teeth
For the purpose of adjusting the edges of the blade with relation to the teeth of the shield I provide at either side of the shield an adjusting-screw
It will be apparent that the blade
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is—
1. In safety-razors, a shield and a blade having the same transverse curvature to conform to each other, teeth formed on the longitudinal edges of said shield, a guard formed on each corner-tooth to receive the corners of said blade, the two corner-teeth of one longitudinal edge being extended beyond the remainder of the teeth of said edge, a roller journaled in said two projecting teeth, and end lugs carried by the shield to engage in notches provided therefor in the ends of the blade.
2. In safety-razors, a shield member and a blade member having the same transverse curvature to conform to each other, end lugs formed on one of said members to engage in notches provided therefor in the other of said members, teeth carried by the longitudinal edges of the shield member and having the two corner or end teeth of one edge projecting beyond the remainder of the teeth of said edge, and a roller journaled in said two projecting teeth.
3. In safety-razors, a shield member and a blade member transversely curved in the same manner to conform to each other, centrally-disposed end lugs carried by one member to engage in notches formed in the other member, teeth formed on the longitudinal edges of said shield member, the end teeth of one longitudinal edge being extended beyond the remainder of the teeth on the same edge, a roller journaled in said extended teeth, and guard-flanges carried by the end teeth of each edge to receive the corners of said blade member.
4. In safety-razors, a transversely-curved shield having teeth on both longitudinal side edges and having the end teeth on one longitudinal side edge projecting beyond the remainder of the teeth on the same edge, a roller journaled in said two projecting teeth, and a transversely-curved blade fitting on the shield the blade and shield having the same transverse curve, whereby the inner face of the blade contacts throughout its surface with the shield.
5. In safety-razors, a toothed shield longitudinally concaved centrally of its upper face and reversely curved at each side of the concave portion, a blade conforming in curvature to the shield and closely fitting on the upper face thereof, and means for securing the blade and shield together.
In testimony whereof I affix my signature in the presence of two witnesses.
