4 Claims.

My invention pertains to improvements in safety razors and more particularly to an improved safety razor for using conventional double edged blades.

It is an object of my invention to provide an improved safety razor of a simple and durable construction which will safely and accurately re-' ceive and hold a conventional double edged safety razor blade.

It is also an object of my invention to provide an improved safety razor which will by a simple sliding movement receive and hold a conventional double edged safety razor blade accurately positioned in the razor head.

It is a further object of my invention to provide improved loading and holding means for accurately positioning and holding a. conventional double edged blade in a predetermined position adjacent the guard surfaces in the safety razor head.

Another object of my invention is to provide an improved safety razor of a construction which may be conveniently and economically made from sheet metal.

Further objects and advantages are within the scope of the invention, such as relate to the arrangement, operation and function of the related elements of the structure, to various details of construction and to combinations of parts, elements per se, and to economies of manufacture and numerous other features as will be apparent from a consideration of the specification in conjunction with the drawings disclosing specific embodiments of the invention, in which:

Fig. 1 is an end elevational view of my improved safety razor;

Fig. 2 is a side elevational view thereof;

Fig. 3 is a. plan view of the razor blade loader and holder, per se;

Fig. 4 is a side elevational view of the loader;

Fig. 5 is an end elevational view of the loader;

Fig. 6 is a plan view of the safety razor head showing the ends of the blade with the loader and holder exposed in the normal manner in full lines and the dotted lines representing how the assembly of blade and holder is inserted or removed;

Fig. '7 is a plan view showing a blank of sheet metal before it has been bent to form the razor;

and Y Fig. 8 is a plan view showing a blank for form'- ing the loader and holder.

Referring more specifically to Figs. 1 and 2 of the drawings, showing the razor on asubstantially enlargedscale, itwill beseen that ,my 'improved safety razor comprises a hollow head II which is open at both ends and suitably conformed for receiving a conventional double edged razor blade l3 inserted from either end. The head is adapted at one side for attachment to the end of a handle l5 of a suitable convenient shape and preferably having the outer surface knurled or roughened for the convenience of the shaver in firmly gripping and holding the razor.

From the hollow of the head a guide groove I! opens outwardly along the median line extending from one end to the other in the outer side of the head away from the handle. As Figs. 3, 4 and 5 show, for loading and holding a conventional double edged safety razor blade I3 in the head, I provide a loader member l9 comprising a base 2| having a. pilot flange 23 of a length and thickness suitable for fitting into the central slot usually provided in double edged razor blades, a blade so installed being represented dotted in Figs. 3 and 4. Then the holder is slidably inserted into the head, from either end thereof, with the pilot flange 23 sliding along in the guide groove H. The loader is also provided with feet 25 projecting from the base in the opposite direction from the pilot flange, and preferably resilient, for snugly engaging the opposite side of the head as the loader is pushed into the head. Fig. 4 shows how a finger 21 of the shaver may be applied to push the loader into the razor head without pressing on the end of the blade. With its pilot flange 23 sliding along in the guide groove H in the head and the feet 25 sliding firmly against the opposite side of the head, the loader holds the blade 13 accurately in a predetermined position relative to the head so that the sharp edges of the blade do not engage the sides of the head.

For exposing the sharp edges of the double edged razor blade l3, the razor head is provided with two elongated slots, or open areas 29, in parallel spaced relations on opposite sides of the guide groove or median line. These two slots, or open areas 29, are of suitable widths and suitably positioned for exposing either sharp edge of the double edged blade and for permitting the skin of the shaver to sweep past and impinge the beard upon the sharp edge of the blade at the most effective angle for shaving, as the adjacent surface 3| of the razor head, on either side of the slot is passed over the face of the shaver. The blade exposing slot 29 adjacent one edge of the blade, ,may be seen in the broken away and sectioned portion of Fig. l, where also it is shown that the head is provid ed with an outwardly projecting ridge or bead 33 so that the sharp blade edge is exposed in a free open space in the head adjacent and slightly inside of the slot.

Finger notches or scallops 35 are preferably provided opening into ends of the razor head at opposite ends of the guide groove 11 to permit insertion of a, finger tip from either side of the razor head to push the blade and its holder into final position or to quickly and conveniently remove it therefrom, as may be seen from Figs. 2 and 6. Additional openings 31 are preferably provided in the head to make it lighter and for washing out the razor under a water faucet, as well as conserving the material of which the razor is made.

The razor and the blade holder and loader, may be made of any suitable material either metallic, or non-metallic, such as plastic composition, which may be cast or molded in accordance with usual practice, as will be readily understood. However, the design of my razor is such that it may be very advantageously made by stamping out a blank 3'!- from sheet metal in the general form represented in Fig. '7. In the same operation the blank may be provided with the blade exposing open areas or slots 29, as well as the finger scallops 35, and other openings 39. Such a blank is then readily formed into the razor head shown in Figs. 1, 2 and 6 in accordance with usual practice in sheet metal working. The blank sheet. is bent along a median line X-X, to form an outwardly projecting fold 40 enclosing the inwardly open and outwardly projecting guide groove 11. The sheet is formed to present the razor head with the two surfaces 3| spaced on opposite sides of the guide groove l1 and oppositely directed at suitable angles for engaging the face of the shaver. These face engaging surfaces include the elongated slots 29 which expose the sharp blade edges and, in order that the blade edges will be exposed in free open space in the head, the sheet is provided with an outwardly bulged bead or flute 33 along the outer margin of each face engaging surface strip, as may be seen most clearly in Fig. 1. The downturned ends of the piece of sheet metal are then conveniently secured to the end of the handle l5, in any convenient manner, or by welding, brazing, or the like. To facilitate this operation,

a slot may be provided in the end of the handle to receive the down-turned end edges of the piece of sheet metal. If the head is formed of plastic composition material, it may be vulcanized or cemented to the handle in accordance with the usual practice in working such materials.

Fig. 8 shows a blank 41 of sheet material of a shape which may be advantageously utilized to form the blade holder and loader of a light sheet construction. This blank may be folded up along the center line X"-X' to form the pilot flange 23, shown in Figs. 3, 4 and 5, and adapted to slidably enter the guide groove I! in the head, after having the center slot ofa double edged blade placed thereon, as shown in Figs. 1 and 6. The sheet is bent laterally from the two opposite sides of the flange 23' to provide a pair of plates'42 which comprise the base for supporting the razor blade. Two strips 43 extending one from each end of the base plates 42 are folded up to form the re- "pilot flange of the holder snugly into the guide groove I! in the head. The areas of the blank 4| which eventually form the pilot flange 23 are enclosed by dotted lines on Fig. 8, as also are the areas which subsequently form the base plates 42.

It is apparent that within the scope of my invention modifications and different arrangements may be made other than herein disclosed, and the present disclosure is illustrative merely, the invention comprehending variations thereof.
