This invention consists in an improved rotary magazine for safety razor blades, including a holder constructed and arranged to be detachably secured to a safety razor when it is desired to deliver a blade thereto and to be detached so that the razor may be used for shaving without the obstruction and added weight of the magazine.
The attempt has been made heretofore to combine a rotary magazine with a safety razor as part of the permanent razor organization, but this combination has not been successful because the weight and bulk of the magazine has proved an intolerable annoyance to the user in manipulating the razor for shaving. Moreover, in such a permanent organization the blades in the magazine are likely to become wetted in flushing the razor. An important feature of the present invention consists in a rotary magazine structure, constructed and arranged to be temporarily secured to the safety razor only during the operation of supplying a fresh blade and to be entirely removed so that it thereafter has no connection with the safety razor. One object of the invention is to provide an improved magazine and holder which may be used in this manner and the various mechanical features of my invention hereinafter pointed out contribute to that desirable end.
As herein shown the body of the magazine consists in a cylinder of wood or other suitable material provided with radial slots opening through the end walls of the cylinder so that the individual blades may be delivered to and withdrawn from the cylinder by endwise movement. The holder for the magazine cylinder is preferably provided with indexing means for locating the cylinder with one or another of its blade-containing slots in line with the blade seat of the razor and if desired for separating the blade-clamping members of the razor itself so that a used blade may be conveniently ejected and a new sharp blade supplied without danger either to the user or to the keen edge of the blade.
Another feature of the invention consists in a holder having a movable blade-feeding device and a rotatable magazine, together with indexing means operative to lock the magazine in any desired angular position for the delivery of a selected blade by endwise movement and simultaneously to register the magazine properly with reference to the blade-feeding device so that the particular blade selected may be engaged and advanced. The invention contemplates a novel relationship between a cylindrical magazine and a blade-feeding device movable in a fixed path, the construction and arrangement being such that when one compartment of the magazine is indexed to register with the blade seat of the razor the same compartment is indexed to register with the said blade-feeding device.
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 cylindrical body
The shape and arrangement of the slots may be adapted to the type of blade which is to be handled. As herein shown the blade is a flat single-edged blade in an order of
The magazine holder, as best shown in
The magazine body
The right-hand ends of the blade seat
The feed slide
When it is desired to rotate the cylinder the feed slide
In this movement the rear projection
An im portant feature of the invention consists in the combination of the narrow inner slots
Having thus disclosed my invention and described in detail an illustrative embodiment thereof, I claim as new and desire to secure by Letters Patent:
1. A magazine for thin sharp-edged blades, comprising a holder, a cylinder mounted for rotary movement in the holder and having a plurality of radial slots opening through the ends of the cylinder, each slot adapted to hold a blade, and means guided by the holder for removing a blade from the cylinder by endwise movement.
2. A magazine for thin sharp-edged blades, comprising a holder having a projecting member for insertion between the blade-clamping members of a safety razor, a magazine cylinder mounted in the holder, and feeding means carried by the holder independently of the safety razor for advancing a selected blade from the cylinder to the razor, the holder thereupon being detachable with the magazine cylinder as a complete unit leaving the blade in the safety razor.
3. A magazine for thin sharp-edged blades, comprising a holder having a longitudinally slotted cylinder rotatably mounted therein, a longitudinal guide member adjacent to one side of the cylinder, a blade-feeder mounted thereon, and means for locking the cylinder in predetermined blade-delivering position and with one of its slots in alignment with the blade-feeder.
4. A magazine for thin sharp-edged blades, comprising a holder having a longitudinally slotted cylinder rotatably mounted therein, a longitudinal guide member extending along and beyond one side of the cylinder, a blade-feeder movable on the guide member in engagement with the cylinder and to a disengaged position beyond the cylinder, and means for temporarily locking the cylinder with a slot in one end of the cylinder in predetermined angular position and at the same time with the circumferential opening of the same slot opposite the said blade-feeder.
5. A cylinder magazine for sharp-edged blades having radial blade slots opening through both ends of the cylinder with each slot merging into a wider channel at the side of the cylinder, each slot adapted to hold a blade which projects therefrom into said channel in combination with a guided blade-feeding device filling said channel and movable endwise therein to advance the blade that projects into said channel.
6. A magazine for thin sharp-edged blades, comprising a holder having upstanding arms, a slotted cylinder journaled to turn between the arms of the holder, one of said arms being slotted and provided with an external finger for temporarily connecting the magazine to a safety razor, and a blade-feeding device movable in the holder to advance any selected blade from the magazine through the said slotted arm and into a safety razor engaged by said finger.
7. A magazine for thin sharp-edged blades, comprising a holder having spaced arms, a spindle therein, a slotted cylinder journaled on the spindle, one of the arms having a blade opening opposite the end of the cylinder, a detent on said arm, a spring tending to move the cylinder and detent into engagement, and a feed slide movable in the holder and simultaneously in one of the cylinder slots.
8. A magazine for thin sharp-edged blades, comprising an elongated holder with angular arms supporting a spindle therebetween, a cylinder mounted for rotary and longitudinal movement on the spindle, an external finger projecting from one of the holder arms, and a slide movable endwise in the holder only when the cylinder is turned to register one of its slots therewith, and means independent of the slide for locking the cylinder in position to deliver a blade in a path substantially parallel to the said external finger.
9. A magazine for safety razor blades having unsharpened end edges recessed in diagonally opposite corners, com prising a radially slotted cylindrical body, each slot adapted to hold a blade, each blade being disposed with the recess in the same end adjacent to the axis of the said body, and feeding means movable in contact with the unrecessed corner of one blade after another.
10. A magazine for sharp-edge blades, comprising a holder and a rotatable cylinder therein; the holder including an elongated longitudinally slotted frame with parallel outturned arms, a spindle removably mounted in said arms, and a detent and an external locating finger carried by one of the arms; the said cylinder being rotatable on the spindle and radially slotted to provide blade pockets, each slot widening into a channel in the surface of said cylinder for receiving said detent, said cylinder being recessed in one end to provide a concentric chamber, and a spring in said concentric chamber tending always to move the said cylinder on its spindle into engagement with said detent.
11. A blade magazine comprising a solid cylindrical body provided with narrow blade-receiving slots radially disposed therein, each slot widening into a channel in the surface of said body.
