Claims.

This invention relates to improvements in razors.

The main objects of this invention are:

First, to provide a safety razor which is efiicient and very convenient to use, and at the same time economical in itsparts both as to the blade holder and the blade.

Second, to provide a safety razor in which the blade may be quickly inserted into or removed from the holder and is securely clamped without the necessity of screws or adjustable parts.

Third, to provide an improved blade for use in this relation.

Objects pertaining to details and economies of the invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure which embodies the features of the invention is clearly illustrated in the accompanying drawing in which:

Fig. 1 is 'a perspective view "of our improved razor with the blade in position.

Fig. 2 is an enlarged longitudinal section on a line corresponding to'line 2-2 of Fig. 3, the parts being shown in 'full lines for convenience in illustration.

Fig. 3 is an enlarged transverse section on line 3-3 of Fig. 2.

Fig. 4 is a plan view of a blank from which the holder is formed. 7

The embodiment of our invention illustrated comprises an inner holder member i of angled cross section and an outer holder member 2, also of angled cross section joined at one end, preferably by the integral strip 3 which holds the outer member under spring tension so that the blade 4 may be inserted between the members. The holder parts are formed as a sheet metal stamping, the inner member part 5 of the blank being somewhat wider than the outer member part B so that it may project beyond the same when the parts are conformed to angular shape and arranged in spaced nesting relation as shown in Fig. 3.

; The edges of the inner member are curved inwardly to provide guards l and preferably have longitudinal clearance slots 8 which are overhungby the cutting edges 9 of the blade. 7

The blade is of angled cross section and is provided with an upturned fingerpiece or lug ii) at one end by means of which it can be conveniently manipulated to insert into or withdraw from the holder. The outer holder member has a portion struck up therefrom to provide an inwardly facing keeper recess l I while the blade has a detent I 2 struck up therefrom engaging this recess when the blade is in assembled relation. There is sufficient resiliency to the blade and to the outer holder member so that the blade is securely retained when it is assembled with the holder as illustrated.

The blade in the embodiment illustrated is beveled at l3 on its inner side onlyso that its cutting edges 9 lie in the planes of the outer sides of the blade. same as the blade of our co -pending application filed April 27, 1936, Serial No. 76,522.

The edges H of the outer member lie adjacent the cutting edges of the blade and serve to effectively support the same, the blade being clamped between the two holder members and supported well to the edge thereof, and this in addition to the angular shape oi" the blade provides a blade which is rigidly supported and does not vibrate or chatter in use; at the same time it is not put under bending stress in the holder so there is no danger of fracturing the metal or distorting or throwing its cutting edges out of position and proper relation to the guard.

It will be understood that in the drawing we have not attempted to show the parts in their exact relation, the cross sectionof the blade being much exaggerated and the dimensions of the other parts being increased in proportion. One of the objects sought and accomplished is to provide a holder and blade with a minimum of stock and at the same time to secure the desired strength and rigidity.

In the embodiment illustrated the handle I5 is of U-sh'a'pe or looped and its arms l'6 terminate in laterally turned lugs 'II which lie within the inner member and are clamped therein by the lugs i8 struck inwardly from the sides of the inner holder member. These lugs are preferably pressed u on the lugs of the holder so that they are partially embedded therein as indicated at l9, Fig. 2.

With this arrangement of parts we provide a safety razor comprising a holder and a blade therefor, both of which may be produced very economically, the blade having cutting edges as described and. claimed in our joint application above referred to. 7

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

1. In a safety razor, the combination of a blade holder comprising inner and outer members of angled cross section spaced to receive a blade between them, the sides of the inner member termi- The blade in this respect is the i nating in inwardly curved guards and having longitudinal slot-like clearance opening above said guards and also having inwardly struck opposed handle engaging lugs, the outer member being integrally connected at one end to one end of said inner member and having a struck-up portion at its apex providing a keeper, a double edged blade of angled cross section slidably engageable between said holder members and having a lug-like finger piece at one end and a detent portion struck up therefrom engageable with the keeper of said outer member, and a U-shaped handle, the arms of which terminate in outwardly directed lugs upon which said handle lugs of said inner holder member are clamped.

2. In a safety razor, the combination of a blade holder comprising inner and outer members of angled cross section spaced to receive a blade between them, the sides of the inner member terminating in inwardly curved guards and having longitudinal slot-like clearance opening above said guards, the outer member being integrally connected at one end to one end of said inner member and having a struck-up portion at its apex providing a keeper, and a double edged blade of angled cross section slidably engageable between said holder members and having a luglike finger piece at one end and a detent portion struck up therefrom engageable with the keeper of said outer member.

3. In a safety razor, the combination of a blade holder-comprising inner and outer members of angled cross section spaced to receive a blade between them, the sides of the inner member terminating in inwardly curved guards and having longitudinal slot-like clearance opening above said guards, the outer member being integrally connected at one end to one end of said inner member and having a struck-up portion at its apex providing a keeper, and a double edged blade of angled cross section slidably engageable between said holder members and having a luglike finger piece at one end and a detent portion struck up therefrom engageable with the keeper of said outer member, the edges of the blade being beveled on its inner side only providing cutting edges substantially in the plane of the outer sides of the blade, the edges of the outer holder member being adjacent to but spaced from the edges of the blade.

l. In a safety razor, the combination of a blade holder comprising inner and outer members of angled cross section spaced to receive a blade between them, the sides of the inner member terminating in inwardly curved guards and having longitudinal slot-like clearance opening above said guards and also having inwardly struck opposed handle engaging lugs, the outer member being connected at one end to one end of said inner member, a double edged blade of angled cross section slidably engageable between said holder members, and a handle having outwardly directed lugs engaged with said lugs of said holder.

5. In a safety razor, the combination of a blade holder comprising inner and outer members of angled cross section integrally connected at one end and spaced to receive a blade between them, the sides of the inner member terminating in guards and having inwardly struck handle engaging lugs, the outer member having a struck-up portion at its apex providing a keeper, a double edged blade of angled cross section slidably engageable between said holder members and having a lug-like finger piece at one end and a detent portion struck up therefrom and having yielding engagement with the keeper of said outer member, and a handle having outwardly directed lugs engaged with said handle lugs.

6. In a safety razor, the combination of a blade holder comprising inner and outer members of angled cross section spaced to receive a blade between them, the sides of the inner member terminating in guards, the outer member having a struck-up portion at its apex providing a keeper, and a double edged blade of angled cross section slidably engageable between said holder members and having a lug-like finger piece at one end and a detent portion struck up therefrom and having yielding engagement with the keeper of said outer member.
