The present invention relates to safety razors of the type in which new blades are adapted to be fed into the head of the razor from a separable blade-filled magazine.
The principal object of the invention is to provide an improved safety razor of the type described, which razor is of new and simplified construction and has but a minimum number of relatively movable parts, which parts are so associated with each other as to function effectively in receiving a blade and in positioning and supporting the blade in shaving position.
Other more specific objects and advantages of the invention will be apparent to those skilled in the art from an understanding of the construction, arrangement and operation of the component razor parts.
For purposes of illustration one embodiment of the invention is presented herein, but it will of course be appreciated that the invention is capable of being incorporated in other structurally modified forms coming equally within the spirit of the invention and the scope of the appended claims.
In the drawings:
The new razor includes a substantially rigid handle
The head
The frame
The head
The plate
The two laterally spaced downwardly tapering end portions
The seat clamping spring
The upper portion
The front cutting edge
With the blade
In order to insert a new blade into the head of the razor, the key
I claim:
1. In a safety razor of the type in which new blades are adapted to be fed into the head of the razor from a separable blade-filled magazine, a substantially rigid sheet metal main frame which is provided at its upper end with a forwardly projecting cap against the underside of which a blade is adapted to be clamped in shaving position, a movable plate in front of the frame, which plate includes a forwardly projecting seat beneath the cap for clamping the blade against the cap and a downwardly extending flange at the rear edge of the seat, said downwardly extending flange provided with a centrally arranged downwardly opening recess the upper edge of which is spaced a substantial distance below the upper edge of said flange and also a substantial distance above the lower edge of said flange, and a leaf spring in front of the frame, the lower portion of said spring rigidly secured against the frame with the upper portion of the spring freely nested within the recess in said flange, and with the upper extremity of the upper portion of the spring bent forwardly out of said recess and positioned in front of said flange, in vertically spaced relation to said seat, and in vertically lapped, rearwardly biased, resiliently yieldable fulcrumming abutment with the upper edge of said recess.
2. In a safety razor of the type in which new blades are adapted to be fed into the head of the razor from a separable blade-filled magazine, a substantially rigid sheet metal main frame which is provided at its upper end with a forwardly projecting cap against the underside of which a blade is adapted to be clamped in shaving position, a movable plate in front of the frame, which plate includes a forwardly projecting seat beneath the cap for clamping the blade against the cap and a downwardly extending flange at the rear edge of the seat, said downwardly extending flange provided with two laterally spaced downwardly extending terminal portions which form between the same a centrally arranged downwardly opening recess the upper edge of which is spaced a substantial distance below the upper edge of said flange and also a substantial distance above the lower edge of said flange, said plate spaced forwardly with respect to the frame except at the lower extremities of the said laterally spaced downwardly extending portions of said flange, where the plate fulcrums against the frame when the blade is in shaving position, and a leaf spring in front of the frame, the lower portion of said spring rigidly secured against the frame with the upper portion of the spring freely nested within the recess in said flange, and with the upper extremity of the upper portion of the spring bent forwardly out of said recess and positioned in front of said flange, in vertically spaced relation to said seat, and in vertically lapped, rearwardly biased, resiliently yieldable fulcrumming abutment with the upper edge of said recess.
3. In a safety razor of the type in which new blades are adapted to be fed into the head of the razor from a separable blade-filled magazine, a substantially rigid sheet metal main frame which is provided at its upper end with a forwardly projecting cap against the underside of which a blade is adapted to be clamped in shaving position, said frame tapering downwardly below the cap and provided along its side edges with downwardly converging forwardly projecting edge flanges which form between the same a shallow forwardly opening pocket, a movable plate in front of the frame, which plate includes a forwardly projecting seat beneath the cap for clamping the blade against the cap and a downwardly extending flange at the rear edge of the seat, which flange is provided with two laterally spaced downwardly tapering portions which are nested snugly but freely between the upper portions of the edge flanges of the frame, said laterally spaced downwardly tapering portions forming between the same a centrally arranged downwardly opening recess, the upper edge of which recess is spaced a substantial distance below the seat and also a substantial distance above the lower extremities of said downwardly tapering portions, and a leaf spring in front of the frame, the lower portion of which spring tapers downwardly, is nested within the pocket formed by the lower portions of the edge flanges on the frame, and is rigidly secured flatwise against the frame, and the upper portion of which spring nests freely within said recess, with the upper extremity of the upper portion of the spring bent forwardly out of said recess in front of the downwardly extending flange of the plate in vertically lapped, rearwardly biased, resiliently yieldable fulcrumming abutment with the upper edge of said recess.
