To all whom it may concern:
Be it known that I, Herman Herder, a citizen of the United States, residing in the city of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Safety-Razors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
My invention relates to safety-razors. Such devices consist of a short razor-blade supported directly in a blade-holder in such manner relatively to one side of the blade edge that the latter cannot bear against the skin to cut it, while being free to contact with the beard, and such blade and its holder are usually mounted in a handle portion to enable the device to be conveniently held in the hand and applied to the face of the operator.
As is well known, the effectiveness of any kind of a razor to shear the beard without a painful pulling effect is due to a manual holding of the blade at a longitudinal incline. In all safety-razors the short blade employed in such devices must be supported in a holder or casing which is usually fastened rigidly to a handle and substantially at right angles thereto, and although it has been suggested to pivot a curved arm on the holder or casing and rigidly fasten the upper end of the handle to this arm that method of securing an inclination of holder to handle is inadequate to properly support the blade-holder during use or to fixedly maintain it at any degree of inclination relatively to the handle. The pivoting means must to be effective form a part of the handle and not of the blade-holder. It must also be movable relatively to the handle in addition to being pivotally connected to the blade-holder and must also independently support the opposite ends of the blade-holder.
The single object of my invention in safety-razors is to effect an adjustable longitudinal incline of the blade relatively to the handle in order that such razors may be used as effectively and without pulling on the beard as the ordinary razor manually operated directly. To that end my invention consists, broadly, in the combination, with a blade-holder for a safety-razor blade, of a divided handle constructed with a single grasping portion, but with a pair of oppositely-disposed and independently-movable forked arms, with pivot connections directly between said arms and the opposite ends of the blade-holder, whereby said arms are movable relatively to each other and to the grasping portion of the handle and whereby the opposite forks of the handle independently support and control the inclination of each side of the blade-holder, operating to adjustably change the angle of the blade to the handle.
In the drawings illustrating an embodiment of that principle of construction constituting my invention,
It is obvious that various forms of combining means between the blade or the blade-holder and the operating-handle to effect an adjustable change of the blade to any incline relatively to the handle may be devised, and hence involve my invention. I have shown in the drawings and will now describe a simple and effective form of device embodying means involving that principle.
The blade holder and guard are shown as consisting of the rear plate 2, curved upward and connected by rivets
Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is—
1. In a safety-razor the combination with a safety-blade and with means constituting a holder therefor as well as a guard for its knife-edge, of an operating-handle provided with a pair of oppositely-disposed forked arms independently movable relatively to each other and to the handle proper, with pivot connections between each of said arms and the blade-holder adapted to adjustably shift the blade-holder longitudinally to an incline relatively to the grasping portion of the operating-handle.
2. In a safety-razor, the combination with a blade-holder, of a divided handle therefor having a single grasping portion, each division of the handle being independently movable and provided with a pair of forked arms disposed opposite to each other in parallel planes, and with means to pivotally mount the blade-holder longitudinally between said arms and laterally between the forks of each of said arms.
3. In a safety-razor the combination with a razor-blade holder consisting of two opposite inclined walls, one of which is provided with guiding-supports for the blade and also with a guard edge, and the other of which is provided with a locking device operating to maintain a razor-blade in suitable relation to the front wall, a detachable razor-blade adapted to be so held in said holder, and an operating-handle consisting of two tubular parts arranged sleeve-like one within the other, the upper end of each tubular portion having projecting arms, those of one tube being connected to the front and rear walls of the blade-holder at one end thereof, and those of the other tube being connected to the opposite front and rear walls of the blade-holder.
4. In a safety-razor the combination with a razor-blade holder consisting of two opposite inclined walls, one of which is provided with guiding-supports for the blade and also with a guard edge, and the other of which is provided with a locking device operating to maintain a razor-blade in suitable relation to the front wall, a detachable razor-blade adapted to be so held in said holder, and an operating-handle consisting of two tubular parts arranged sleeve-like one within the other, the upper end of each tubular portion having projecting arms, those of one tube being connected to the front and rear walls of the blade-holder at one end thereof, and those of the other tube being connected to the opposite front and rear walls of the blade-holder; the periphery of the outer of said tubes being longitudinally slotted, and a set-screw passing through said slot with its screw end entering the periphery of the inner tube of the operating-handle.
In testimony whereof I have hereunto affixed my signature this 11th day of December, A. D. 1903.
