This invention relates to that class of magazine razor in which the magazine of blades is temporarily attached to the razor for the purpose of supplying a fresh blade, the razor being used for shaving apart from the magazine.
The present invention is directed to a razor in which the blade is held in proper shaving position to the guard by a movable part of the shaving head that is provided with a tapered portion that exercises a wedging action against the back edge of the blade. The movable part is preferably made slidable in the shaving head and is held in normal clamping position by a spring. The spring not only holds the movable part in contact with the blade but also holds the movable part against lateral movement.
The invention relates, further, to a co-operation between the movable part and a top plate over the blade that causes the said part to raise the top plate slightly thus relieving the pressure on the top of the blade when the wedge is moved out of contact with a blade in the razor and also out of the path of travel of an incoming blade which latter blade is fed into the razor in rear of its position and is in turn moved forwardly to proper position when the wedge pushes it forwardly on the removal of the blade magazine.
The invention is illustrated in the accompanying drawing in which
The shaving head comprises a blade platform
The magazine is in the main not new and comprises a casing
Various details may be varied without departing from the scope of the invention as set forth in the claims.
1. A safety razor comprising a holder for maintaining a blade in shaving position, a slidable part in the holder, said part including a wedge for yieldingly maintaining the blade by engagement with its back edge, a blade magazine having means for ejection of a blade, and a finger on the magazine and insertable in the holder and having a surface for moving the slidable part out of engagement with the blade.
2. A safety razor comprising a blade holder having a blade platform, a back piece spaced from the blade platform, a slidable part in the space, the part having a wedge for engaging the back edge of a blade, a spring for moving the part, in combination with a blade magazine, means for ejecting a blade endwise from the magazine, and a finger on the magazine adapted for entry into the holder and for positioning the holder and magazine relative to each other, the slidable part and the finger having co-acting surfaces for moving said part out of contact with the blade when the holder and magazine are assembled.
3. A safety razor comprising a shaving head having means for grasping a blade and adapted to receive a blade endwise, the shaving head including a slidable part having a wedging portion for engaging the back edge of the blade, a magazine, a slide on the magazine for ejecting a blade from the magazine endwise into the shaving head, and a finger on the magazine for engaging the shaving head and so positioning the magazine relative to the shaving head, said finger when engaged contacting the slidable part to move the wedging portion out of the path of the ejected blade, and a spring for moving the slidable part into contact with the blade.
4. A safety razor comprising a shaving head including a blade platform and a back plate, said back plate having a forwardly extending top plate to hold a blade on the blade platform, a movable part between the blade platform and the back plate, a wedging portion on the movable part for engaging the back edge of a blade, a spring to hold the movable part in normal position in engagement with a blade, the blade platform and the movable part being recessed on opposed faces, a magazine for blades, means on the magazine for feeding blades therefrom, and a finger in the magazine and adapted to enter the recesses for positioning the magazine on the razor and moving the movable part out of normal position.
5. A safety razor comprising a shaving head including a blade platform and a back plate, the back plate having a forwardly extending top plate to engage the blade on the blade platform, a movable part between the blade platform and the back plate and having a wedging portion, the shaving head having a recess adjacent the movable part, a magazine for blades, a finger on the magazine for entering the recess for positioning the magazine on the razor and moving the movable part out of normal position, the movable part having a portion to engage the top plate whereby the top plate is raised by said movable part when the magazine and razor are assembled.
6. A safety razor comprising a shaving head including a blade platform, a top plate for engaging the top of a blade on the platform, a slidable part having a wedging portion for engaging the back edge of a blade in the shaving head and positioning it in shaving position, a magazine for blades, a finger adapted to engage the shaving head for positioning the magazine in position for feeding a blade to the shaving head, said finger also engaging the slidable part to disengage it from the blade, said slidable part also contacting the top plate to raise it slightly when the blade is not engaged by the slidable part.
