Application May 2, 1947, Serial No. 745,477

2 Claims.

This invention relates to safety razors and has for one of its objects to provide a novel construction by which the assembling of the blade with the guard and clamping member and the clamping of the blade between these parts, as well as the unclamping of the blade when it is to be removed, is facilitated.

Other objects of the invention are to provide novel constructional features which will be more fully hereinafter set forth and then pointed out in the appended claims.

In the drawing wherein I have illustrated a selected embodiment of my invention,

Fig. 1 is a view of a safety razor embodying the invention.

Fig. 2 is a section on the line 2-2, Fig. 1.

Figs. 3 and 4 are fragmentary sectional views showing difierent embodiments of the invention.

Fig. 5 is an enlarged perspective view of the head or guard member.

Fig. 6 is a section through the razor on the line 66, Fig. 5, showing the backing or clamping member in its raised position.

Fig. '7 is an enlarged view through the as sembled head and clamping member on the line 1--'!, Fig. 2.

Fig. 8 is a section on the line 8-8, Fig. 2.

Fig. 9 is a perspective view of a double-edged razor blade such a adapted for use in my improved razor.

In the drawings l indicates the head or guard member, 2 the blade-backing or clamping member, and 3 is the blade which is clamped between the head or uard member and the clamping member 2; these being the parts usually found in double-edged safety razors. The handle for the razor is indicated generally at 1. It is provided with a stem section 5, the end portion 6 of which is screw threaded and has screw threaded engagement with the'clamping member 2, the

head or guard member I having an openin '3 through which the screw-threaded portion 6 of the stem passes and said stem having a shoulder 8 to engage the back face of the guard.

-the section !3 of the handle and is preferably adjustable in said section in an axial direction. The side walls of the tubular sections I2 and I3 are preferably of some opaque material through 2 which light will not b transmitted. The front end of the handle section 62 is closed by a disk or head member 2i which makes a water tight joint with the side wall of said section 12 and which is of some translucent or transparent material through which light may be transmitted. Said disk 2! may be of glass or may be of some transparent plastic material, of which the material sold under the trade name ,Lucite is an example. The head 2! i preferably provided with a plurality of recesses 22 which form thin places 23 thereby to facilitate the transmission of light through the head 2i if it is made of material which is more or less translucent.

Inasmuch a the side walls of the tubular sections 32 and 83 do not have light-transmitting lqualities, the light from the bulb it will be projected through the disk or head member 2! only,

and thus the illumination provided by the bulb is limited to a small area immediately circumjacent the head or guard member.

The stem 5 of the handle extends from the head 2| and if said head is made of Lucite or some other similar plastic material, the stem and head may be made as an integral one-piece element, the end of the stem being provided with the screw-threaded portion 5. as above described.

The circuit wires leading to the terminals of the socket ie are indicated at It and I1 respectively and are shown as connected to a plug terminal 6i adapted to be plugged into any suitable outlet. The circuit wire ll has therein a switch 7 iii of any usual type which is provided with a thumb piece Ed by which it can be operated. The Switch l8 herein shown is of the type having a screw-threaded stem is which has screw threaded engagement with an opening in the end of the handle section it, the thumb piece !9 proecting through the casing and thus being accessible for manipulation,

As stated above the lamp socket is is capable of adjustment axially of the handle so as to position the light H nearer to or further from the r head 2| thereby providing for varying the size be understood that there is sufficient slack in the cords it, I! to permit such adjustment of the lamp socket.

24 indicates a sleeve of rubber or other yielding material which surrounds the bulb and provides tending pin 31.

a cushion therefor thus reducing or eliminating the danger of breakage.

The head I and the clamping member 2 are designed to take any double-edged flexible blade now on the market, and for this purpose the head I is provided with two ribs 25, one on either side of its central hole I, which ribs are of a size to fit the central slot 6| with which double-edged razor blades are usually provided. The clamping member 2 is provided on its under side with recesses 26 to receive the ribs 25 when the razor blade is tightly clamped to the head.

The clamping member 2 is shown as having on its under side two transverse ribs 2'0 which are engaged in the transverse slots 28 with which double-edged razor blades are commonly provided, the head I having transverse recesses 29 to receive said ribs 21.

The head I is provided adjacent each guard edge 30 with a groove or gutter 3! which extends the full length of the head and which is located directly underneath the cutting edge of the blade 3, the purpose of this gutter being to receive the lather and cuttings and also to provide a construction by which such lather and cuttings can be readily flushed from the razor by simply holding the razor head under a stream of water from the faucet or agitating the head in a body of water. These grooves or gutters 3I are open at the ends so that any accumulation therein is easily washed out.

In order to provide a proper support for the razor when it is clamped between the body I and the head, I will preferably provide one or more bridge portions 32 which extend across the mouth of the gutter or groove.

In my improved razor the blade-backing or clamping member 2 is permanently connected to the head I, and spring means are provided whereby when the handle is unscrewed from the clamping member, the latter will be raised from the head thus allowing the blade 3 to be removed. For assembling the blade with the head, it is only necessary to insert the blade between the head and the raised backing member and then to press the clamping member into engagement with the head and to screw the handle into the aperture of the backing member thereby closing said clamping member solidly against the blade and clamping the latter in position.

The spring means I have herein shown for this purpose comprises two helical spring elements 35 which are anchored both to the head I and the clamping member 2. The head I is made relatively thick as shown in Figs. and 6, and each corner on one side is provided with a recess 36 to'receive one end of the corresponding spring 35,

said spring being anchored in the recess in any suitable way as by means of a transversely ex- The upper end of each spring 35 is received in a recess 38 formed in a corner of the clamping member 2, said spring being anchored in the recess 23 by means of an anchoring pin 39.

When the clamping member 2 is clamped against the blade as shown in Fig. 2, the springs 35 are compressed within the recesses 35 of the head I, the latter being thick enough to accom modate the compressed springs.

When the handle is unscrewed, the springs expand and raise the clamping member as shown in Fig. 6, and said springs are stiff enough to hold raised the clamping member in a position substantially parallel to the head I. When the clamping member has thus been raised, the blade can be readily removed from the side of the head opposite to that carrying the springs 35.

' Similarly, when the blade is to be introduced into the head, it is slipped into position from the left, Fig. 6, until it is properly positioned by the ribs 25 and then the handle is screw threaded to the clamping member and the latter is clamped against the blade.

Double-edged blades for razors of this type are usually made with recesses or notches 48 at the corners, and the springs 35 are located so that when the blade is in position, they occupy the notches at the corners of the blade.

In the construction shown in Figs. 2 and '7, the stem 5 of the handle is provided with an exteriorly screw-threaded end portion 6 which has screw threaded engagement with a tapped hole in the clamping member 2.

There are many safety razors adapted for use with a double-edged blade in which the clamping member has a screw-threaded stem that extends through an opening in the head I, and the handle has an interiorly screw-threaded socket at its end adapted to screw on the stem of the clamping member.

In order to enable my improved handle with its light attachment to be used with a razor of this type, I have provided an adapter 4| in the form of a sleeve having interior screw threads adapted to receive both the screw-threaded stem of the clamping member 2 and the screwthreaded end 6 of my improved handle. Such an adapter is shown in Fig. 3 as being mounted on the screw-threaded end 6 of the handle embodying my invention and as having screw threaded engagement with the stem'% of the clamping member 2a.

In Fig. 4 I have shown my improved handle as applied to a safety razor having the single edged type of blade. In said figure, 43 indicates the head of the razor which is provided with the usual screw-threaded stem 44 onto which the razor handle is usually screwed. In applying my improved handle to this type of razor, an adapter II will be used which is screw threaded onto the stem 43 and which provides an interiorly screw threaded socket to receive the exteriorly screwthreaded portion 6 of the stem 5 of my improved handle.

I claim: 1. A safety razor comprising a head elemen having a guard portion at each side and also having a central aperture, a blade-clamping member for clamping a blade against the head element, said blade-clamping member having a centrally located tapped hole, a handle provided with a shoulder to engage the head element and a screw-threaded portion to screw into said tapped hole, helical springs situated between the head element and the blade-clamping membenmeans connecting one end of each spring to the bladeclamping member and means connecting the other end of each spring to the head element, said springs serving to separate the blade-clamping member from the head element when the handle is unscrewed and also serving as means for connecting said blade-clamping member and head when they are so separated.

2. A safety razor comprising a head element having a guard portion at each side and also having a central aperture, a double edged razor blade having a notch in each of its four corners, a blade-clamping member for clamping said blade against the head element, said blade-clamping member having a centrally located tapped hole,

a handle provided with a shoulder to engage the head element and a screw threaded portion to screw into said tapped hole, two helical spring elements, one located at each end of the head element and both being on the same side of the head, means connecting one end of each spring element to the head, means connecting the other end of each spring element to the blade-clamping member, said spring elements being situated to occupy the notches in the corresponding corner of the blade when the latter is clamped between the head and the blade-clamping member, whereby when the handle is unscrewed from the bladeclamping member the springs operate to separate the latter from the head and support it in its separated position.
