To all whom it may concern:

Be it known that I, Morris S. Jacobson, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Safety-Guards for Razors, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to safety-guards for razors; and the object thereof is to provide a device of this class which is simple in construction and operation and which may be connected with an ordinary razor-blade; and with this, and other objects in view the invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed.

The invention is an improvement on that described and claimed in United States Pattent No. 570,598, granted to me November 3, 1896, and is fully disclosed in the following specification, of which the accompanying drawings form a part, in which—

Figure 1 is a side view of a razor-blade provided with my improved guard and showing a portion of the handle; Fig. 2, an end view looking in the direction of the arrow a in Fig. 1; Fig. 3, a section on the line 3 3 of Fig. 1; Fig. 4, a view similar to Fig. 1, showing a modification; Fig. 5, an end view looking in the direction of the arrow a³ of Fig. 4, and Fig. 6 a section on the line 9 9 of Fig. 4.

In the drawings forming part of this specification the separate parts of my improvement are designated by letters of reference in each of the views.

In the drawings, A represents an ordinary razor-blade having a shank a, and B a portion of the handle, and in the practice of my invention I provide a guard D, the outer end of which is bent inwardly or transversely of the end of the blade to form an arm d, and I also provide a clamp G, which is oblong in form and which is adapted to be placed upon the back of the blade A and to clamp the same throughout its length, said clamp being provided with spring sides g, which press upon the sides of the blade.

It will be understood that the back of the blade is thicker than the body portion thereof, and the sides g of the clamp G are inwardly-curved or bent so as to grasp the same, as shown in Figs. 2 and 5. The upper portion of the clamp G, at the outer end thereof, is bent downwardly, as shown at g², and the arm d of the guard projects into the end of the clamp and is pivoted therein, as shown at g³. The inner end of the guard D is also curved upwardly to form a supplemental arm d², which is provided with a loop d³, through which the shank a of the blade A passes, and the upper portion of the loop d³ is pivotally connected with the end of the back of the clamp G, as shown at d⁴. As thus constructed the guard D is free to swing transversely of the edge of the blade A, but only to a slight extent, the limit of the movement of the guard being determined by the sides of the clamp G, which are struck by the arm d of the guard, and also by the side loop d³, which are struck by the sides of the shank a of the blade. This movement, however, is sufficient to permit of the free operation of the blade, and at the same time the guard is held in such position with reference to the edge of the blade that the cutting of the face in the operation of shaving is practically impossible. This movement of the guard is effected by slight pressure on the face in the opera. t;on of shaving, and when one side of the blade is placed against the face the guard swings past the edge and to the opposite side of the blade.

The same movement of the guard takes place when strapping or honing the razor, and this movement allows the razor to be cleaned or sharpened without removing the guard; but one feature of this invention consists in the fact that the guard may be quickly and easily detached whenever necessary for sharpening or honing the blade.

In Figs. 4 to 6, inclusive, I have shown a modified form of construction, in which the arm d of the guard, is passed upwardly through the end of the clamp G and pivoted thereto, as shown in Fig. 1, by means of the pivot-pin g³, and the arm D is provided with a plurality of perforations through which said pivot-pin may be passed, and thus the position of the guard D may be adjusted with reference to the edge of the blade. The arm d² is formed into a loop or yoke d³, as in Figs. 1 and 3, and the sides of said loop or yoke are projected upwardly and provided with transverse perforations through which the pivot-pin or bolt d⁴ is passed, and the end of the clamp G is provided with an upwardly-directed shoulder d⁶, through which said pivot-pin or bolt also passes, and the sides of the loop or yoke d³ are also provided with a plurality of perforations, and this end of the guard may also, therefore, be adjusted with reference to the edge of the blade. The operation of this form of construction will also be similar to that shown in Figs. 1 to 3, inclusive, as hereinbefore described, and it will be seen that the principle of the construction and operation in each of the modifications herein described and illustrated is the same.

Having fully described my invention, I claim as new and desire to secure by Letters Patent—

1. A guard for the blade of a razor adapted to be detachably connected therewith and consisting of a rod or bar which extends longitudinally of the edge of the blade, and a clamp which is adapted to be connected with the back of the blade, said clamp being provided with side plates which are adapted to grasp the side of the blade, the outer end of said rod or bar being provided with an angular arm which extends into or through the outer end of said clamp, and is pivotally connected therewith, and the end of said rod or bar adjacent to the shank of the blade being also provided with an arm which is provided with a yoke or loop through which the said shank passes, said loop or yoke being pivotally connected with the back of the said clamp at the end thereof, substantially as shown and described.

2. A guard for the blade of a razor adapted to be detachably connected therewith and consisting of a rod or bar which extends longitudinally of the edge of the blade, and a clamp which is adapted to be connected with the back of the blade, said clamp being provided with side plates which are adapted to grasp the side of the blade, the outer end of said rod or bar being provided with an angular arm which extends into or through the outer end of said clamp, and is pivotally connected therewith, and the end of said rod or bar adjacent to the shank of the blade being also provided with an arm which is provided with a yoke or loop through which the said shank passes, said loop or yoke being pivotally connected with the back of the said clamp at the end thereof, and said rod or bar being also adjustable toward or from the edge of said blade, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 5th day of May, 1807.
