To all whom it may concern:
Be it known that 1, Arthur J. H. Lefebvre, a subject of the King of Great Britain, residing in the city and district of Montreal, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Safety-Razors; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to new and useful improvements in razor-guards adapted to be applied to form so-called “safety-razors” and it consists in certain features of novelty in the detail construction and arrangement of the clamping means therefor, all as hereinafter more fully described, and specifically pointed out in the claims.
The object of the invention is to provide a razor-guard which may be adapted for application to any ordinary razor without special fittings and adjustments of the parts thereof, whereby the guard may be quickly applied and as quickly removed from an ordinary razor-blade to form a safety-razor.
Referring to the drawings, in which similar numerals of reference indicate corresponding parts in all the views,
Referring to the parts,
The upper portion of the guard-plate
When it is desired to place the razor-blade in position, all that is necessary is to throw the tongues
In use the razor may be manipulated in the ordinary manner common to razors of this class.
While I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myself to the precise form shown, for many of the details may be changed in form or position without affecting the operativeness or utility of my invention, and I therefore reserve the right to make all such modifications as are included within the scope of the following claims or of mechanical equivalents to the structures set forth.
Having described my invention, what I claim, and desire to secure by Letters Patent, is—
1. A razor-guard comprising a guard-plate, blade-clamps thereon, a laterally-projecting ledge on said guard-plate, a spring extending longitudinally thereof, and a locking-tongue pivotally mounted between said spring and said ledge.
2. A razor-guard comprising a guard-plate, blade-clamps thereon, a laterally-projecting ledge on said guard-plate, a spring extending longitudinally thereof, and a cam-shaped locking-tongue pivotally mounted between said spring and said ledge.
3. A razor-guard comprising a guard-plate, blade-clamps thereon, a laterally-projecting ledge on said guard-plate, a spring extending longitudinally thereof, and a plurality of tongues each of which has integral pintles and cam extensions, said tongues being mounted between said spring and said ledge.
In witness whereof I have hereunto set my hand in the presence of two witnesses.
Arthur J. H. Lefebvre.
