This invention relates to safety razors and particularly to a safety razor utilizing the same mechanical principle and having the same general construction as that set forth in my prior application bearing Serial No. 422,798.
The objects of the invention are to provide improved means for holding the device in the hand, which means will tend automatically to direct its shaving action most effectively, and to provide for simple and quick assembly and permanent connection of related parts.
In achieving these objects, in place of the usual handle with a straight axis, I employ a handle of rectangular section whose front and rear faces present compound curves, whereby important practical advantages are gained in use of the device, and I so form related portions of the blade receiving head and of the handle as to obviate the use of screw threaded or riveted connection such as has heretofore been expedient.
The specific nature of my improvements and the practical advantages resulting therefrom will be made evident by reference to the accompanying drawing and the following description and claims.
In this drawing:
In making an upward stroke in shaving beneath the chin or upon the neck, the fingers naturally assume a position substantially similar to that indicated in
It is to be noted that various relative proportions of the handle and modifications of its curvature have been tested in shaving use and that the relative proportions of the handle in relation to the average size male hand as indicated in
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. A safety razor including a blade receiving head and a handle, said head having a channel portion with the outer edges of its side walls flanged inwardly, said handle having an end portion with a
2. A safety razor including a blade receiving head and a handle, said handle having a flat end wall and opposed grooves adjacent thereto, said head having a projection with a flat wall for engagement with said end of the handle, side walls for engagement with portions of the side walls of said handle and flanges penetrating said grooves in the side walls of the handle, said flanges having teeth for biting into the material composing said handle whereby the engaged parts are retained in fixed relation.
3. A safety razor including a blade receiving head and a handle with one end connected to said head and a butt end opposite said head end, said handle having flat side faces of sufficient width to form a broad bearing surface for the fingers to prevent twisting in use, a curved front face and a curved rear face, said front face being concave adjacent said butt end and convex adjacent said head end and said rear face being convex adjacent said butt end and concave adjacent said head end.
4. A safety razor blade holder comprising a blade-holding head having a guard, and a handle which adjacent its head is at the rear bowed toward the guard, and adjacent the butt bowed in the opposite direction, with a forwardly-extending heel, and having lateral faces of sufficient width to form a broad bearing surface for the fingers to prevent twisting in use.
