To all whom it may concern:
Be it known that I, Leonidas H. Cress, a citizen of the United States, residing in West Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.
My invention relates to that class of safety razors in which the blade is detachably connected with its holder in order that it may be readily resharpened or replaced by a new one. In this class of razors the blades are now commonly made thin to economize metal and to facilitate manufacture and thus render the cost of production so low that a blade after having been used a few times may be thrown away.
The primary object of my invention is to provide a blade holder which is simple in construction, easily manipulated and so inexpensive to manufacture that the razor may be sold at a small retail price and thus come within the reach of those who have not heretofore been able to procure a safety razor of good quality at a reasonable cost. According to my invention I employ a thin steel blade of an improved form and I provide a holder comprising two plates rigidly connected together at their rear edge and having a space between them for the blade. One of the plates carries a guard of the usual kind and the lower plate is provided with a threaded socket to receive the threaded end of the handle which threaded end extends entirely through the lower member of the holder and bears upon the under side of the blade when the latter is positioned. The space between the two members of the holder is shallow, being sufficient only to permit the blade to be slid into place from the front rearward, and the blade is formed with laterally projecting and rearwardly extending ears which serve to position it in the holder and prevent side- wise movement therein. When the blade is secured in the holder by the handle its front portion is raised very slightly from contact with the under member of the holder and when the blade is withdrawn after use any soap or lather which may have found its way between the members of the holder will be drawn out in the act of removing the blade.

As so few parts are involved in the construction of my razor and as each part is plain and simple it may be manufactured at small cost, and the manner of manipulating it is so obvious that no one will have the slightest trouble in using it properly.
I claim as my invention:
1. A safety razor, comprising a thin blade and a blade-holder, consisting of upper and lower plates of substantially the same area rigidly and permanently connected at their rear edges by a flange which extends from side to side of the holder and having a shalow blade space between them large enough only to admit the blade, the lower plate being provided with a threaded socket extending through it at an acute angle to the plane of the blade and a handle having a threaded shank extending through the socket at an acute angle to the plane of the blade and the front portion only of which engages the blade and holds it firmly against the rear flange of the holder.
2. A safety razor consisting of a holder, comprising two members rigidly connected at the rear by a flange extending the full width of the holder and having a blade space between them, a blade having front and rear edges of substantially the same length formed on its opposite side edges below its rear edge with laterally projecting lugs having portions extending rearwardly beyond the rear edge of the blade adapted to engage the opposite ends of the rear flange of said holder to prevent lateral movement of the blade, and means for clamping the blade in the holder.
In testimony whereof, I have hereunto subscribed my name.
