No. 779,233.Patented Jan. 3, 1905.
United States Patent Office.

Lingue S. Morgan, of Kendall, Kansas. Razor.
SPECIFICATION forming part of Letters Patent No. 779,233, dated January 3, 1905. Application filed August 29, 1904. Serial No. 222,616.

To all whom it may concern:

Be it known that I, Lingue S. Morgan, residing at Kendall, in the county of Hamilton and State of Kansas, have invented a new and Improved Razor, of which the following is a specification.

My invention seeks to provide a new and improved razor which includes a peculiar design or form of a cutting-blade, together with other details of structure, all of which will be hereinafter fully described, specifically pointed out in the appended claim, and illustrated in the accompanying drawings, in which—

Figure 1 is a side view of my improved razor with the blade opened. Fig. 2 is a similar view, the blade being closed.

In the drawings, A designates the blade, which is pivotally mounted in the combined handle and casing B in the usual manner and which comprises a shank a and a cutting-blade member a′, the peculiar form of which forms the essential feature of my invention. The cutting edge of the blade a′ at the heel is curved abruptly upwardly and convexedly, as at 1, and over the said abruptly-curved portion 1 the cutting edge curves gradually and continuously in a convexed manner toward the front or toe end of the blade, at which point (designated 2) it curves upwardly substantially in the arc of a circle, as at 3, with respect to the extreme outer end 4 of the back of the blade, with which the extreme end 3a of the curved portion of the said outer end merges, that portion between the parts 3a and 4 being concaved, as indicated by 5, whereby to produce the toe extension that terminates in a rounded projection x, the purpose of which will presently appear. The handle or casing B has its lower end b curved inwardly, as at b′, in approximately the same angle that the forward end of the blade is curved, whereby to properly receive the blade, as shown in Fig. 2.

By reason of the peculiar formation of the cutting edge of the blade a more perfect shearing action is effected on the beard during the act of shaving, for the reason that during a straight pull on the blade over the face a running cut is produced—that is, the cutting edge of the blade travels or constantly changes, as it were, in the longitudinal direction of the blade, thereby effecting a more perfect and safe cutting of the beard in the hollow places of the face and neck, and, furthermore, since the curvature of the cutting edge terminates in an abrupt circular line ending at the small protuberance or toe projection x the forward end of the blade can be the more freely rocked during the operation of shaving and which also permits the blade being handled in such manner that the hand will not throw a shadow over that part of the face being shaved, especially while trimming the face above the ear.

I am aware that razors having convexed cutting edges and curved toe ends have heretofore been provided; but my invention, so far as I know, differentiates from what has heretofore been provided in the peculiar continuous curvature of the cutting edge and the exact formation of the different parts thereof, all of which will be pointed out in the appended claim.

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

A razor having a blade whose cutting edge comprises an abruptly-curved portion that merges with the shank, a convexed curved portion that extends from the abruptly-curved portion to a point near the forward end of the blade from which point the cutting edge curves in an arc of a circle with the extreme outer edge of the razor-back as the axis, the extreme outer edge of the said cutting edge terminating in a narrow projection, said projecting end being connected with the extreme outer end of the back by a concaved portion, substantially as shown and described.

Lingue S. Morgan.
