No. 793,410.Patented June 27, 1905.
United States Patent Office.

Ernst Julius Bell, of Foche, near Solingen, Germany. Safety-Razor.
SPECIFICATION forming part of Letters Patent No. 793,410, dated June 27, 1905. Application filed February 21, 1905. Serial No. 246,711.

To all whom it may concern:

Be it known that I, Ernst Julius Bell, a citizen of the German Empire, residing at Hauptstrasse 15, Foche, near Solingen, Germany, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to a safety-razor where the blade is secured to the end of a flat-handled bar, on which it can be turned and adjusted to assume any desired angle therewith; and its object is to provide a safety-razor provided with a guard, as usual, but offering additional advantages over similar devices heretofore in use. One of these advantages is that it can be used either as a safety-razor or adjusted as an ordinary razor; and another benefit is the great convenience with which it can be handled, permitting a convenient shaving even of those places of the human face the access to which was rather difficult for the devices heretofore employed.

In describing my invention I refer to the drawings herewith, in which—

Figure 1 is a side view of my safety-razor so adjusted as to be ready for use for shaving the right side of a face. Fig. 2 is another side view of my device with the blade adjusted in transverse position. Fig. 3 is a side view of the guard; Fig. 4, a transverse section through a nut and a spring to go on the screw projecting from the guard illustrated in Fig. 3. Fig. 5 shows the handle consisting of two parts—viz., a flat bar f and the handle g; and Fig. 6 is a side view of the said handle, to which is secured the blade of the razor.

My device comprises a blade a, over the back of which is, as usually, drawn a guard b, carrying a safety device d, adjustable by means of screws c, sliding in suitable slits. From the back of the said guard projects a male screw e to receive a flat bar f, provided for the purpose with a suitable perforation and being fastly secured by a female nut and a cylindric spring h. This arrangement permits the placing of the blade in lengthwise position to the said bar and handle or across the same or in any desired angle. To adjust the blade in the position first mentioned, there are provided on the back of the guard b wedged projections k, engaging in corresponding recesses l of the said flat bar f, while the fixing of the blade in transverse position or in any other angle is done by the construction of the said flat bar f, by which it grips the back of the said guard and is pressed against the same by the aforesaid spring h. To the said flat bar f may be secured the handle g, for which purpose it is equipped with a box m, into which fits the shank n of the said handle g, provided with a longitudinal groove, into which engages a key end of the guard as a means for preventing an overturning.

My contrivance may be taken apart and adjusted for use as an ordinary razor. With this object in view the aforesaid shank n of the handle g is provided with a threaded end o and the blade with a corresponding female bore q, into which it may be screwed. This arrangement permits a convenient removal of the guard from the blade, as well as an easy cleaning and honing of the same.

What I claim as my invention, and desire to protect by Letters Patent, is—

A safety-razor comprising the combination of a razor-blade provided on the ends with a female screw-bore, a safety-guard b ending in a key end, a perpendicular male screw e and wedged prominencies projecting from the back of the said guard, a flat bar provided with perforations corresponding to the said male screw and prominencies, a cylindric spring and a female nut to go on the said male screw, a handle with a shank provided with a longitudinal groove to correspond with the key end of the aforesaid guard and a male screw corresponding to the aforesaid female bores in the end surfaces of the blade, substantially as described and for the purposes set forth.

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

Ernst Julius Bell.
