This invention consists in an improved magazine safety razor in which by simple manipulation of a feeding device the user may at any time present in shaving position a fresh blade from a magazine located in the razor head. The razor is designed to receive a magazine or clip containing a supply of blades in which the blades, if desired, may be dispensed for sale to the public. The blade magazine is arranged to be dropped into the head of the magazine instead of having to be pushed in endwise as heretofore, this being a particularly convenient mode of replenishing the blade supply and requiring little or no mechanical skill on the part of the user.
With this end in view an improved feature of the invention consists in a safety razor having in its head a guard and an open channel adjacent to the guard, in combination with a magazine shaped to fit freely into the channel so that it may be dropped directly in place therein and be positioned or registered by fitting in the channel for supplying blades directly in shaving position above the guard.
Another feature consists in a detachable or removable magazine having a feeding device movably mounted thereon and assembled with the magazine, that is to say, the feeding device is an adjunct of the magazine and remains with it rather than with the razor frame. The magazine with or without the feeding device in some embodiments of the invention may be used as a dispensing receptacle comprising with its enclosed blades an article of commerce.
Means may be provided for locating the magazine in place when it has once been inserted in the channel of the razor head and such means serve to retain the magazine in operative position until the supply of blades contained therein has been exhausted. Preferably and as herein shown the locating means may have the further function of clamping the feeding device to prevent chance or accidental ejection of a blade or other displacement of the parts during the shaving operation.
These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof, selected for purposes of illustration and shown in the accompanying drawing, in which:—
The razor illustrated herein comprises a frame consisting of a handle having a knurled barrel
The bottom plate
The magazine comprises a rectangular enclosure
The blades
Associated with the magazine is a feed member comprising a rectangular shell of thin sheet metal having a back wall
The bottom plate
Assuming that the razor contains a blade in shaving position, as shown in
It will be seen that the entire operation of replacing one blade for another involves two complete reciprocations of the feeding device and that the old blade is completely ejected from the razor before a new blade is advanced from its completely guarded position in the magazine.
A fresh blade may be advanced into operative position at any time before or during the shaving operation, that is, if the user finds a blade to be unsatisfactory while shaving
The feeding device is movably retained on the magazine by the free travel of the projections
If desired, the recesses
