SAFETY-RAZOR.

sem s.

Be it known that I, CHARLES R. RAGSDALE, a citizen of the United States, residing at St. Louis and State of Mlssouri, have invented certain new and useful Improve-- ments in Safety-Razors, of which the following is a'specification.

My invention relates to safety razors of that type in which a blade is provided which is held between a backing and a guard piece, the guard piece being provided with a handle whereby the razor may be manipulated.

.The object of my invention is to provide a very simple, effective and relatively cheap construction, wherein the use of means mounted on the handle for adjusting the guard plate relatively to the blade is eliminated, and wherein the blade may be positively held for any length of time in fixed relation to the guard.

\ My invention is shown in the accompanying drawings in which Figure 1 is a perspective view showing my improved razor assembled. Fig. 2 is a perspective view showing the parts of the razor disassembled; and Fig. 3 is a view showing the three different sizes of caps used for clamping theguard, blade and back plate of the razor together. a

Referring to these drawings, 5; designates aguard plate which is oblong. in form and which is laterally curved, and 3 designates the handle of the razor which is rigidly attached to the guard plate in any suitable manner. The side edges of the guard plate for a portion of their length are formed with projecting fingers 4. The blade 5 of the razor is slightly narrower than the guard plate 2, but is of the same length as the guard plate. The extremities of the blade are cut away at each end as at 6, and the middle portion 7 at each end of the blade has the same width as the ends of the guard plate, the main portion of the blade having a width slightly less than the distance between the extremities of the fingers 4. It

will thus be seen that registering shoulders are provided upon the guard plate and upon the blade. The back plate 8 is rectangular in shape and is laterally curved, the curve of the back plate corresponding to the curve of the guard plate. The back plate is not cut away at its ends, but the side edges of the back plate are entirely straight from one end to the other, the back plate having the same length as the guard plate and as the Specification of Letters Patent.

blade. The back plate has a width equal to the width of the portion 7 of the blade, and equal to the width of the guard plate at its extremities. Thus it will be seen that when the blade is placed upon the guard plate and the back plate placed thereon, the side edges of the ends of the guard plate, of the blade and of the back plate, will all register. F or the purpose of holding the guard plate and the back plate in position against each other and the blade in place between the .two and preventing any shifting of the blade, I provide the caps 9, these caps being either open or closed at their ends and laterally curved so as to fit over the extremities of. the guard plate, the blade and the back plate. It will be seen that these caps when pushed home fit against the shoulders formed by the cutaway portions of the guard plate and blade, and hold these three parts in rigid relation. It will also be seen that the distance between the opposite sides of the caps 9 will regulate the distance between the guard plate and the edge of the blade. By using different size caps for the ends I can adjust the razor for close, light or medium shaving, the thinner and tighter fitting the cap is, the closer the blade will be set to the the shave. The larger the caps are, the farther away the blade will be from the guard, thus giving a close shave. In order to assemble the razor with the blade in place, it is only necessary to take the back plate, the blade and the guard, in one hand with the blade between the guard plate and the back plate, press all three of the parts together so that the blade is bent between the two plates, and then place the caps one over each end until the caps rest against the shoulders formed by the cut away portions of the blade and guard plate. The razor is then in condition for use. In order to remove the blade,'it is only necessary to pull the two caps off the ends and the parts are disassembled and ready to be cleaned.

It will be seen that my invention is Very simple, cheap to manufacture, easily manipulated, and in practice it has been found to be thoroughly effective. Further it will be seen that by adjusting the blade, guard plate and back plate by means of the caps 9, I do away with the necessity of using the handle as an adjusting means. Where the handle is used as'the means for clamping the blade between the back plate and guard, and therefore the lighter caps, the blade will always have its proper adjustment in relation to the guard and back plate.

What is claimed is:

1. In a safety razor, a transversely curved guard-plate, a handle attached to the guardplate, a transversely curved back-plate, a blade disposed between the guard-plate and the back-plate, and laterally curved clips extending transversely across the ends of the guard-plate engaging over the side edges of the guard-plate, blade and back-plate at the corners thereof holding the three in rigid engagement with each other.

2. In a safety razor, a'guard plate having "laterally disposed shoulders at its opposite ends, a blade having laterally disposed shoulders at its opposite ends registering with the shoulders on the guard plate, and a back plate, a handle attached to the guard plate, and caps fitting over the ends of the guard'plate, blade and the back plate and against saidshoulders, and holding the'parts in rigid relation to each other.

3. In a safety razor a guard plate rectangular in plan and laterally curved, a handle attached to the guard plate, the opposite extremities of the guard plate being formed with laterally disposed shoulders, a blade formed at its opposite ends with laterally disposed shoulders and resting against the guard plate, and a back plate resting against the blade and having a width equal '45 to the narrowest portion of the blade and a length equal to the blade, and caps fitting over the ends of the black plate, blade and guard plate, and holding the same in rigid relation to each other.

4:. In a safety razor, a guard plate laterplate being provided with outwardly projectlng fingers, the side edges of the ends of the guard plate being straight, a blade of the same length as the guard plate and having laterally disposed cut away portions on its corners registering with the ends of the ally curved, the middle portion of the guard guard plate, and a back plate laterally",

curved and having a width equal to the width of the ends bf the blade, and a length equal to said blade and guard plate, and hollow caps laterally curved fitting over the endsof the guard plate, blade and back plate, and holding the parts in rigid relation to each other.

In a safety razor, a laterally'curved guard plate, the middle portion of both edges of the guard platebeing provided with projecting guard fingers, the side'edges of the ends of the guard plate beyond said fingers being straight and parallel to each other, a blade of the same length as the guard plate and of a width slightly less than the distance between the extremities of the guard fingers, the corners of the blade being cut away to form oppositely disposed shoulders at the ends of the blade, the extremities of the blade having a width equal to the width of the extremities of the guard plate, a laterally curved back plate having a width along its whole extent equal to the width of the ends of the blade and a length equal to said blade and guard plate, a handle projecting from the face of the guard plate, and hollow caps laterally curved and fitting snugly over the ends of the guard plate, blade and back plate and hold the parts in rigid relation to each other. e

In testimony whereof, I afiix my signature in presence of two witnesses.
