To all whom it may concern:
Be it known that we, Malcolm T. Heil and Clifton T. Heil, citizens of the United States, residing at Allentown, in the county of Lehigh and State of Pennsylvania, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.
This invention comprehends certain new and useful improvements in safety razors, and the invention has for its primary object an improved device of this character which will possess to a marked degree the characteristics of simplicity and durability of construction, and efficiency of operation, in that the blade and guard are of elongated diamond shape with a handle rigidly, though detachably secured thereto and extending at right angles therewith, the shape of the blade affording a maximum shaving surface as well as affording means whereby an effective shearing cut may be secured without changing or adjusting the position of the handle, whereby a portion of the edge passing over the face will be followed by other portions of such edge in a shearing stroke, so as to practically go over the face a number of times with the one and same operation, and whereby, by a simple axial movement of the handle without any adjustment thereof, the said blade may be turned or rocked on the face from one edge to an adjacent edge forming an obtuse angle therewith, so as to effectively change the position of the blade in passing from one portion of the face to another, as from the cheek, around the cheek bone to the neck, without removing the razor from the face.
Our invention also has for its object an improved safety razor in which the parts are rigidly, though detachably connected together in such a manner that none of the fastening means are exposed or in the way, which will permit the parts to be readily cleansed and easily assembled without danger of breaking any of the parts or of cutting one's hand with the blade in applying the same.
A further object of the invention is a device of this character which is so arranged that any desired thickness of blade may be employed, from a wafer blade to a comparatively heavy one, the blades being secured in place and held in a rigid position relative to the guard or body portion of the device.
The invention has for its object an improved construction of safety razor, which, owing to the shape of the blade and guard as above described, with its acute points renders it peculiarly adaptable for shaving certain parts of the face, such as under the nostrils and around the ears and neck, which would be impossible with a safety razor of other shape. And a further object of the invention is a device of this type provided with an improved construction of strop device whereby a section of the handle may be removed from the body portion or guard and secured to a blade holder so that the blades may be resharpened by stropping or honing, and thereby increase their usefulness.
With these and other objects in view as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that we will hereinafter fully describe and then point out the novel features thereof in the appended claims.
For a full understanding of the invention and the merits thereof, reference is to be had to the following description and accompanying drawings, in which:
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
Referring to the drawing, the numeral
In order to hold the cap plate in position to clamp the blade solidly upon the plane surface of the guard plate
From the foregoing description in connection with the accompanying drawing, it will be seen that we have provided a very simple, durable and efficient construction of safety razor; owing to the diamond-like formation of the guard plate and blade, a maximum cutting surface is afforded, while at the same time, a shearing cut may be secured without any necessity of adjusting the blade to different inclinations or angles relative to the handle, the blade being at all times held in a plane at right angles to the length of the handle and being secured firmly in place by fastening means that are not exposed. The construction at the same time enables the parts to be readily detached one from the other and cleansed, and as readily reassembled, it being only necessary, in assembling the parts, to hold the blade fist in the palm of one hand, without any danger of cutting one's hand and to then apply the guard plate by holding it by its handle section
Having thus described the invention, what is claimed as new is:
1. A safety razor, comprising a guard plate formed on its upper side with studs, and an opening between and in alinement with said studs, a hollow handle section secured to said plate in registry with said opening, a blade adapted to rest on said plate and formed with openings adapted to receive said studs, and with an intermediate opening adapted to register with the opening in the plate, and a cap plate adapted to rest upon the upper surface of the plate and formed with sockets receiving the ends of said studs, said cap plate being provided with a stem designed to extend through the opening in the plate and through the hollow handle section and designed to hold the blade upon the guard plate, and a complementary handle section, adapted to slip over the end of the first mentioned handle section and arranged for engagement with the said stem whereby to draw it firmly upon the blade and clamp the latter between the cap plate and guard plate.
2. A safety razor, comprising a guard plate formed on its upper side with studs, a perforated blade arranged to rest upon said guard plate, with the studs passing through the perforations, a cap plate adapted to rest upon the blade and formed in its lower face with sockets terminating short of the upper face of the cap plate, and receiving the studs, means for clamping the cap plate upon the blade, and a handle.
3. A safety razor comprising a guard plate, a blade adapted to rest upon said guard plate, a cap plate adapted to rest upon the blade, a handle section secured to said, guard plate, a stem secured to the cap plate and passing through the blade and guard plate and through the handle section with a lower threaded extremity protruding from the lower end of the handle section, said handle section being provided at its lower end with a reduced neck and a complementary handle section provided with a slip socket by which it is adapted to be slipped over the reduced neck, and formed below said socket with interior threads designed to engage the threaded extremity of the stem as and for the purpose set forth.
In testimony whereof we affix our signatures in presence of two witnesses.
