SAFETY-RAZOR.

Specification of Letters Patent.

Patented May 15, 1917.

Application filed August 28, 1915. Serial No. 47,779.

To all whom it may concern:

Be it known that I, CARL O. ENGSTROM, a citizen of the United States, residing at Sacramento, in the county of Sacramento and State of California, have invented certain new and useful Improvements in Safetyazors, of which the following is a specification.

The present invention relates to improvements in razors, and more particularly to that typ of razor wherein the cutting edge of the blade is protected by a guard.

The invention has for its principal objects to provide a razor wherein the angle of the blade is capable of being varied to regulate the position of the cutting edge thereof relatively to the blade support, whereby the beard may be out at various distances from the skin surface; to provide a razor having a pivotal connection between the handle and the blade holder, the ful crum point of which is approximately on a line parallel with the cutting edge of the blade, thereby enabling the blade cutting edge to follow the contour of the face; to provide a blade guard which is spaced from the cutting edge of the blade, thereby adapting the blade to cut along its entire cutting edge.

With the above mentioned and other obthe invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in the claims hereto appended; it being understood that various changes in the form, pro portion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

To more fully comprehend the invention, reference is directed to the accompanying drawings, wherein-- Figure 1 is a view in plan of an embodiment of my improved razor.

Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is a plan view of removed from the handle.

Fig. 4 is an enlarged sectional view in detail, disclosing the blade adjusted at different inclinations in the blade support.

Fig. 5 is an enlarged detail view of one the blade support of the blade holding fingers disclosing the rolling action of the blade thereover.

Referring more particularly to the several views of the drawings, wherein like charucters of reference designate corresponding parts throughout the several views, 1 indicates a suitable flat plate bent upwardly at its opposite side edges as at 2. From each end of the front edge 3 of the plate 1 extend the blade holding fingers 4 having upturned points 5 and upwardly projecting rounded shanks 6. The side edges 2 of the plate ex tend outwardly beyond the front edge 3 of the plate and are connected by a transverse member 7 downwardly from which project the inwardly curved spaced guard fingers or teeth 8 which terminate on a line slightly in advance of the blade holding fingers a. The cutting edge 9 of a blade 10 is received in the curved portion of the blade holding fingers 4: and the rear edge of the blade is received in the notches'll of a yieldable rctaining arm 12, preferably positioned centrally of the rear portion of the plate 1 and secured thereto.

The adjustment of the rear edge of the blade 9 in the notches 11 of the arm 12 causes the front portion of the blade to roll on the rounded shanks 6, which will cause the cutting edge 9 to be raised or lowered relatively to the front edge 3 of the plate 1. The spacing of the guard in front of the cutting edge enables the blade to perform a cutting action for its full length.

Fulcrumed in the upwardly bent side edges 2 of the plate 1, with their pivotal axis in a plane approximately parallel with the cutting edge 9 of the blade, are the bent ends 13 of the handle members 14, twisted together as at 15 forming a handle to be grasped by the operator.

spring 16 is carried by one of the side edges 2 and engages one of the handle mem bers let and maintains the blade holder in a plane with the handle 15.

After adjusting the blade for the proper cut of beard, the operator grasps the handle 14 and placing the underside of the plate 1 to the flesh draws the razor downwardly, which causes the guard to first pass over the beard followed immediately by the cutting edge of the blade, which, owing to the arrangement of the guard capable of a cutting action for its full length. By ful- CJI cruming the blade holder and handle together on a line approximately parallel with. the cutting edge of the blade, the overhang or rear portion of the holder forms a guiding or directing surface, which, during the movement over the flesh causes the cutting edge of-the blade to follow the contour of the flesh, the spring 16 serving to normally maintain the plate 1 in a plane parallel with the handle.

By withdrawing the bent ends 13 of the members lis from their fulcrum seats, the handle and blade supporting portion are capable of being easily separated.

"he blade holder is capable of being shaped or folded from a single piece of metal when desired which enables the same to be easily and cheaply manufactured, and the forming of the handle from a single piece of material enables this part to be manufactured at little cost, and it will be apparent that the invention is capable of being manufactured at little cost, contains but few parts and is capable of being quickly taken apart and assembled when desired.

Having thus described my invention what I claim is 1. A safety razor comprising a blade holder, a blade for'positioning therein, a guard in advance of the cutting edge of the blade and in spaced relation thereto, and a handle pivotally connected to said blade holder and permitting a movement of the holder independently of the handle when the holder is being drawn across the face, the pivotal axis of which is above the cutting edge of the blade and adjacent the front edge of the holder.

2. A safety razor comprising a blade holder, a blade for positioning therein, a guard for the blade, and an operating handle pivotally connected to said blade holder, the fulcrum point of which connection is located above the cutting edge of the blade holder, whereby the blade holder is permitted to have a movement independently of the handle to allow the same to follow the contour of the face.

3. A safety razor comprising a blade holder, a blade for positioning in the holder, a guard for the blade, means for adjusting the rear edge of the blade to vary the angle of the cutting edge thereof, and an operating handle fulcrumed to the blade holder at a point above the cutting edge of the blade and near the forward edge of the holder, permitting the blade holder to have a movement independently of the handle to allow the same to follow the contour of the face.

1. A safety razor comprising a blade holder, a. blade for positioning therein, a guard for the blade, an operating handle fulcrumed to the blade holder above the cutting edge of the blade, said holder being capable of a movement independently of the handle whereby the blade follows the contour of the face, maintaining said blade holder in a plane parallel with said handle.

5. A safety razor comprising a blade holder, a blade removably positioned therein, a guard for the blade, an operating handle extending in a plane at substantially right angles to the cutting edge of the blade and fulcrumed to the blade holder above the cutting edge of the blade and near the forward portion of the holder, permitting a movement of the holder independently of the handle to allow the same to follow the contour of the face, and means for normally maintaining said blade holder in a plane parallel with said handle.

6. A safety razor comprising a blade holder, a blade removably positioned therein, a guard for the blade, an operating handle extending in a plane at substantially right angles to the cutting edge of the blade and fulcrumed to the blade holder near its forward end on an axis approximately parallel with the cutting edge of the blade and capable of a movement independently of the handle when the holder is drawn across the face, and a spring cooperating with the blade holder and handle for normally maintaining the same in a parallel plane.
