The object of my invention is to provide a safety razor in which a guard member is provided with blade guarding means along a substantially medial portion of said member and with means to detachably retain one or more blades with the cutting edge extending inwardly in relation to the guarding means, whereby when blades are used in the razor with their cutting edges extending inwardly either cutting edge may be used according to the direction of travel of the razor along a face to be shaved.
In carrying out my invention I provide a guard member having guarding means for a blade edge located along a medial or substantially central portion of the member, means to support one or more blades on said member with their cutting edge in shaving relation to said guarding means, and means to detachably retain said blades in shaving position.
A further embodiment of my invention includes a resilient blade retainer carried by the guard member and having edge portions normally bearing against the blades to retain them in shaving position, said retainer being adapted to be flexed or bent from the normal position to release the blades for removal and replacement.
My invention also comprises novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims.
Reference is to be had to the accompanying drawing, wherein
Similar numerals indicate corresponding parts in the several views.

I provide means to bear against the blades to keep them in shaving position against the blade supports including the stops or abutments
With the parts as shown in
With the cutting edges of the blades facing the centrally disposed guard teeth one blade may be used for shaving with the razor head or holder moved in one direction along a face, and by reversing the direction of movement of the razor the other blade may be used for shaving, the razor thus being capable of shaving when moved on opposite directions. By tilting the blade holder from one position to another, as in
My improvements are simple and cheap to manufacture, and are easily manipulated for removal and replacement of blades in the holder without requiring any parts to be detached.
Having now described my invention what I claim is:—
1. A safety razor comprising a guard member having guarding means located along a medial portion of said member, a series of spaced projections on said member for supporting a pair of blades with their cutting edges in shaving relation to said guarding means, and means to detachably retain said blades in shaving position on the guard member, the blade retaining means including a piece of metal having sides embracing the guard member and having edge portions extending inwardly over the blades to retain them in shaving position.
2. A safety razor comprising a guard member having guarding means located along a medial portion thereof, means to support blades on said member with their cutting edges in shaving relation to said guarding means, and means for detachably retaining said blades in position including a piece of metal extending along the outer sides of the guard member, the mid-portion of said piece being spaced from the guard member to permit bending and outer portions of said piece bearing against marginal portions of the guard member, edge portions of said piece extending inwardly over the blades.
3. A safety razor comprising a guard member having guard teeth between its marginal portions, means to support blades on opposite sides of said guard teeth with their cutting edges adjacent to said teeth, and a retainer for the blades comprising a piece of resilient metal having a portion located along the side of the guard member opposite the guard teeth, said retainer having marginal portions enclosing marginal portions of the guard member and having inwardly extending edge portions to engage the blades to retain them on the supports.
4. A safety razor as set forth in claim 3 provided with means loosely attaching the retainer to the guard member.
5. A safety razor as set forth in claim 3, in which the retainer is provided with holes and the guard member is provided with rivets located in said holes to keep the retainer in position on the guard member and permit the retainer to bend.
6. A safety razor comprising a guard member having guard teeth, means to support a blade with its cutting edge adjacent to said teeth, the guard member having a handle, and a blade retainer having a mid-portion provided with a hole receiving said handle, side portions of the retainer bearing against marginal portions of the guard member, an edge portion of the retainer being extended over the guard member to retain a blade on said support.
7. A safety razor comprising a guard member having guard teeth along a mid-portion of the member, blade supports on opposite sides of said teeth, the guard member having a handle, a blade retainer having a mid-portion spaced from the guard member and provided with a hole receiving the handle, said retainer having portions bearing against the guard member and having side portions extending around marginal portions of the guard member and edge portions extending over the guard member to retain blades on said supports.
8. A safety razor as set forth in claim 7 in which the mid-portion of the retainer extends away from the guard member to be bent toward the latter to cause the edge portions of the retainer to move away from blades on the guard member.
