Amos H. Jackson, of Fremont, Ohio. Safety-Razor
No. 807,172. Specification of Letters Patent. Patented Dec. 12, 1905.
Application filed August 7, 1905. Serial No. 807,172

To all whom it may concern:

Be it known that I, Amos H. Jackson, a citizen of the United States, residing at Fremont, in the county of Sandusky and State of Ohio, have invented certain new and useful Improvements in Safety-Razors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to that class of razors commonly known as “safety-razors;” and it consists of the general arrangement of the several parts and their novel combination, as will be hereinafter fully described in this specification and briefly stated in the claims.

Many of the so-called “safety-razors” are composed of numerous parts and are quite complicated in their construction, in consequence of which great difficulty is experienced in keeping them clean and free from rust, it requiring considerable time after each shaving operation to take the implement apart, clean the several parts, and put it together again. This requirement has been found to be very objectionable in this class of razors; and one of the principal objects of this invention is to overcome this very serious objection, and I accomplish it by producing an implement composed of as few parts as possible and of the simplest and cheapest form of construction, but while composed of only two parts great care has been exercised to make these parts durable and have them effective in operation.

In the drawings, Figure 1 is a side elevation of my improved implement; Fig. 2, a central transverse section; Fig. 3, a perspective view of the guard detached, and Fig. 4 a modification.

Referring to the several views, the numeral 1 indicates the razor-blade, 2 the guard, and 3 the handle. The blade may be of any suitable or required length and is of the hollow-ground variety of type.

The guard and handle are preferably composed of a single piece of metal, said guard being provided at its lower edge with teeth or fingers 4, which curve slightly outward away from the blade and extend a slight distance beyond the cutting edge thereof. The teeth by means of their outward curvature and extension beyond the cutting edge of the blade serve as a guide for the blade as it passes over the face. The upper part of the guard is formed with clasps 5 integral with the guard, and between said clasps and the inner face of the guard the blade is adjusted, the blade being held in position by means of a set-screw 6, passing through the guard.

The handle is flat and is curved upwardly and outwardly to form a proper and convenient grasp for the thumb and fingers.

In the modification shown in Fig. 4 the set-screw is dispensed with and the blade is held in position by means of spring-clamps 10 10, cut from the face of the guard.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is—

1. A safety-razor consisting of a blade, a guard constructed of a single piece of metal and having its lower edge provided with outwardly-curved teeth, extending slightly beyond the cutting edge of the blade, said guard being slitted at two points to form a handle and end clamping or gripping lips or flanges, and means for holding the blade in adjusted position.

2. A safety-razor consisting of a blade, a guard constructed of a single piece of metal and having its lower edge provided with outwardly-curved teeth, extending slightly beyond the cutting edge of the blade, said guard being slitted at two points to form a handle and end clamping lips or flanges, said handle being bent in reverse direction to the lips, and means for holding the blade in adjusted position.

In testimony whereof I affix my signature in the presence of two witnesses.

Amos H. Jackson.
