To all whom it may concern.
Be it known that I, King Camp Gillette, a citizen of the United States, and a resident of London, England, have invented new and useful Improvements in Razors, of which the following is a specification.
My invention relates to safety-razors of that type in which the blade is provided with perforations or equivalent openings and is held between a backing and a guard-piece, with respect to which it is positioned by means of pins or the like passing through the perforations in the blade, such a razor being described and claimed in my application for United States Letters Patent, Serial No. 84,552, filed December 3, 1901, of which application this present application is a division.
The razor specifically shown and described in my said prior application has a thin flexible blade provided with two opposite cutting edges, and the two sides of the holder are made alike, the handle being symmetrically disposed midway between them, so that either edge of the blade can be used without altering its position in the holder; and my present improvements are herein shown and described as embodied in a razor has the same general characteristics—that is to say, a double-edged flexible blade, a double guard, and a symmetrically-disposed handle; but it is to be understood that this particular construction and arrangement of these parts is not essential to the main features of my present invention.
Referring to the drawings,
For securing the backing and guard together I provide a pin or bolt
When the parts are assembled, the blade
When the blade and guard are double-edged, as shown, the sleeve
In the construction illustrated the adjacent surfaces of the guard and backing conform in area and contour, or substantially so, thus providing rigid supporting-surfaces for the blade throughout practically the entire area I of the latter when clamped between said parts, and in order to utilize the flexibility and elasticity of the thin blade for the purpose of obtaining an adjustment of its cutting edges toward and from the edges of the guard these conforming-surfaces of the guard and backing are somewhat curved transversely, so that the blade is bent transversely and its cutting edges are caused to approach closer and closer to the notched edges of the guard as the guard and backing are drawn together or permitted to spring away from said notched edges as the guard and backing are separated. In
In order that the blade may be readily grasped by its ends when it is desired to remove it from the holder, I prefer to construct these parts in such manner that the ends of the blade at and near its longitudinal center will project slightly beyond the ends of the backing at the corresponding points, which may be done by forming a suitable recess
It is one of the features of my present improvements that after the guard and handle have been detached from the backing the blade may still be held in place on the backing by means of the positioning-pins and may be grasped by its ends and readily applied or removed without having to be slid laterally between the sides of a supporting framework, as has been practice heretofore.
I claim as my invention—
1. In a razor, the combination with a perforated blade, of a holder comprising a handle, a backing provided with positioning-pins arranged to pass through the perforations in the blade, a guard, and means for clamping said blade between the backing and the guard.
2. In a razor, the combination with a perforated flexible blade, of a holder comprising a handle, a rigid backing forming a support for said blade and provided with positioning-pins arranged to pass through the perforations therein, a guard, and means for clamping said blade between the backing and the guard.
3. In a razor, the combination with a perforated blade, of a holder therefor comprising a backing having positioning-pins secured thereto and adapted to pass through the perforations in the blade, a screw-threaded bolt secured to said backing and passing through a perforation in the blade, a guard arranged to engage the opposite side of the blade and having perforations adapted to receive said pins and bolt, a handle having one end internally screw-threaded to receive said bolt.
4. In a razor, the combination of a transversely-curved rigid backingprovided with inwardly-pointing positioning-pins and a central screw-threaded bolt, a guard curved transversely to correspond with said backing and having its opposite longitudinal edges notched, a flexible blade having two opposite cutting edges and provided with perforations arranged to receive the bolt and positioning-pins, and a handle having its inner end internally screw-threaded to receive said bolt.
5. In a razor, the combination with a perforated blade of a holder comprising a guard, a handle, a backing, and clamping means passing through the blade, said blade and backing being so formed that the ends of the former project beyond the ends of the latter.
6. In a razor, the combination with a perforated blade having two opposite cutting edges, of a holder comprising a double guard having perforations corresponding to those in the blade, a backing provided with positioning-pins passing through the blade and guard, a handle, and means for detachably clamping the blade between said backing and guard.
7. In a razor, a holder comprising a backing provided with positioning-pins and with a central screw-threaded bolt, a double guard provided with perforations adapted to receive said positioning-pins and bolt, and a handle provided with an internally-screw-threaded nut adapted to receive said bolt.
8. In a razor, a holder comprising a transversely-curved, rigid backing provided with positioning-pins and with a screw-threaded bolt, a guard curved transversely to correspond with said backing and perforated to receive said positioning-pins and bolt, and a handle provided with an internally-screw-threaded nut adapted to receive said bolt.
9. A safety-razor comprising a back plate, a clamping-plate, a handle projecting from said plates at substantially a right angle, a sleeve connected to said clamping-plate and mounted on the handle, and means for adjusting said plates toward and from each other.
10. A safety-razor comprising a back plate having lugs, a blade, a guard, both the blade and guard having openings for said lugs, and means for securing the plate, blade and guard together.
In testimony whereof I have hereunto subscribed my name this 10th day of May, 1904.
King Camp Gillette.
